Objective To investigate the variation of total hospitalization cost for single-diagnosed disease of different types of acute appendicitis in a three-A hospital, so as to provide evidence for the reimbursement amount of social medical insurance. Methods All patients with acute appendicitis who had surgery treatment during January-April 2011 (before implementing the fee system for single-diagnosed disease) and January-April 2012 (after implementing the fee system for single-diagnosed disease) were collected in this study for analysis. According to the types of acute appendicitis, the patients were stratified into the low risk group (simple, suppurative and gangrenous) and the high risk group (perforative, abscess-formed and pregnancy-combined). The correlation between total hospitalization cost and types of acute appendicitis, as well as the changes of total hospitalization cost after implementing the fee system for single-diagnosed disease were analyzed. Results A total of 90 eligible patients were included. The disease types were positively correlated with hospital stays and total hospitalization cost. All three types in the low risk group could control the average total hospitalization cost within RMB 10 000 yuan. The results of sensitivity analysis showed that, before implementing the fee system for single-diagnosed disease, the total hospitalization cost up to RMB 6 000 yuan could be positively correlated with the above risk stratification (r=0.442, P=0.003). After implementing the fee system for single-diagnosed disease from January to April 2012, the constituent ratio of hospital stays, compared with that in the same period of 2011, had no significant difference (P=0.108) between the two groups; but the ratio of hospital stays (less than 5 days) increased from 45% to 64%, and the ratio of hospital stays (greater than or equal to 10 days) decreased from 17% to 4%, indicating a tendency of shortening hospital stays. Also, the constituent ratio of total hospitalization cost had no significant difference (P=0.114) between the two groups; but the ratio of total hospitalization cost (greater than or equal to RMB 9 000 yuan) decreased from 32% to 13%, indicating a tendency of lowering total hospitalization cost. Conclusion The low risk group of acute appendicitis, RMB 6 000 yuan should be rated as the rational reimbursement amount of social medical insurance. The total hospitalization cost for the high risk group is quite various, so the further studies are needed to investigate the feasibility of the fee system for single-diagnosed disease as well as the rating amount of total hospitalization cost. The implementation of the fee system for single-diagnosed disease is helpful to shorten hospital stays and reduce total hospitalization cost.
Forty-five pancreatoduodenectomies had been performed in our hospital from 1981 to 1994, of which 35 cases were diagnosed as carcinomas of Vater’s ampulla or pancreatic head, and 10 (cases) as benign lesions. Through analysis of misdiagnosed cases, the authors emphasize that it is important to take correct history of jaundiced patients in detail according to the character of the jaundice and associated symptoms before any operation done. Secondly, all clinical materials must be thoroughly collected and special examinations for diagnosis should be chosen scientifically to avoid relying only on one sort of examination result as diagnostic standard. Thirdly, during operation the area of pancreatic head should be explored carefully and any lesions in doubt should be examined pathologically by puncture biopsy and frozen section to avoid misdiagnosis and thus performing pancreatoduodenectomy.
Objective?To compare the effect of continuous subcutaneous insulin infusion (CSII) with that of multiple daily insulin injections (MDI) in the patients with newly-diagnosed type 2 diabetes, and to provide evidence for clinical treatment. Methods?We searched MEDLINE and Chinese Science and Technology Full-text Database up to Dec. 2009 to identify randomized controlled trials (RCTs) that had been conducted with patients with newly diagnosed type 2 diabetes mellitus. The selection of studies, data extraction and assessment of methodological quality were performed independently by two reviewers. Meta-analyses were performed using RevMan 5.0.23 software. The following outcomes were assessed: glycaemic control, insulin requirements, HOMA-IR, HOMA-β, hypoglycaemia and diabetic remission after follow-up. Results?Eight RCTs involving 597 newly-diagnosed type 2 diabetic patients were included. The methodological quality of the most studies was lower. The funnel plot comparing insulin requirement of CSII therapy with that of MDI therapy showed asymmetry, indicating that there was publication bias. The results of meta-analyses showed that: CSII had the same effect on improving fasting blood glucose (WMD= –0.21, 95%CI –0.42 to 0.00, P=0.05) and postprandial blood glucose (WMD= –0.24, 95CI% –0.57 to 0.08, P=0.14) as MDI in newly-diagnosed type 2 diabetes. CSII therapy took 2.74 days fewer than MDI therapy (WMD= –2.74, 95CI% –3.33 to –2.16, Plt;0.000 01) and needed lower insulin requirements (reducing 7.78 units per day) (WMD= –7.78, 95CI% –9.25 to –6.31, Plt;0.000 01) to get target glucose control. The rate of hypoglycaemia of CSII therapy decreased 69% (OR= 0.31, 95%CI 0.12 to 0.80, P=0.01) compared with that of MDI. The rate of diabetes remission after short-term intensive insulin therapy increased 46% (OR=1.46, 95%CI 1.01 to 2.10, P=0.04) in CSII therapy compared with that in MDI therapy. Conclusion?In newly-diagnosed type 2 diabetes, CSII therapy is better than MDI therapy. But because of the low quality of the included studies, the conclusion should be combined with patients and physicians’ experience, advantages and disadvantages in the clinical application.
Acquaintance of the lymph node is very important to evaluate whether the tumor is malignant or benign and therefore to the treatment of the tumors. Lymphography is now considered the gold standard for this purpose. Many computer aided diagnose (CAD) technologies have been developed to help radiologists to diagnose the tumor by the lymphography cases. In this paper, a computer aided diagnose model is constructed by Semi-naive Bayes Classification. The experiments carried out in our laboratory validated the Semi-Naive Bayes Classification on lymphography case. The result of experiments showed that Semi-Naive Bayes Classification could classify lymphography case effectively.

MethodsTo collect the clinical data of newly diagnosed adult epilepsy from October 2016 to February 2017, and to follow up 6 months. ResultsA total of 81 patients were included. At the last clinic visit, 73 cases origined from focal, 74 cases were positive in EEG examination, 56 cases were unknown etiology, 12 cases had hippocampal sclerosis, 48 cases were mildly declined cognitive function, and 30 cases were poor compliance. ConclusionThe newly diagnosed epilepsy were focal origin, delayed treatment, mildly declined cognitive function and poor compliance.
Objective The study was performed to compare the efficacy and effect on quality of life of sodium valproate (VPA) sustained-release tablets versus topiramate (TPM) in newly diagnosed adult symptomatic epilepsy. Methods This is aprospective, randomized controlled trial on 200 patients newly diagnosed as adult symptomatic epilepsy in Sichuan Province People’s Hospital druing September 2014 to December 2016. The patients were randomly divided into VPA group (n=110) and TPM group (n=90). Then we evaluated the efficacy, retention rate, adverse reactions, and quality of life of the two groups after one year of treatment. Results The total effective rate of VPA group was 69.1%, and the rate of no seizures was 38.2%; the total effective rate of TPM was 62.2%, and the rate of no seizures was 42.2%. No statistically significant difference in the effective rate and no seizure rate was found between the two groups. There was no statistical difference in the retention rate between the two groups(69.1% vs. 65.6%, P>0.05) . The incidence of adverse reactions of VPA was significantly lower than that of TPM (9.1%vs. 20%, P<0.05). The quality of life of the two groups was significantly improved from baseline before treatment. VPA group showed significantly better performance than TPM group on mood and cognitive improvement (P<0.05). Conclusion ① There was no significant difference in efficacy and retention rate between VPA sustained-release tablet and TPM on adult patients with symptomatic epilepsy after one year's treatment; ② The incidence of adverse reactions of TPM group was significantly higher than that of VPA group; ③ VPA sustained-release tablets and TPM can significantly improve the overall quality of life of patients, and VPA sustained-release tablets is significantly better than topiramate on the improvement of emotional and cognitive function.
ObjectiveTo study the efficiency and difference of the artificial intelligence (AI) system based on fundus-reading in community and hospital scenarios in screening/diagnosing diabetic retinopathy (DR) among aged population, and further evaluate its application value. MethodsA combination of retrospective and prospective study. The clinical data of 1 608 elderly patients with diabetes were continuously treated in Henan Eye Hospital & Henan Eye Institute from July 2018 to March 2021, were collected. Among them, there were 659 males and 949 females; median age was 64 years old. From December 2018 to April 2019, 496 elderly diabetes patients were prospectively recruited in the community. Among them, there were 202 males and 294 female; median age was 62 years old. An ophthalmologist or a trained endocrinologist performed a non-mydriatic fundus color photographic examination in both eyes, and a 45° frontal radiograph was taken with the central fovea as the central posterior pole. The AI system was developed based on the deep learning YOLO source code, AI system based on the deep learning algorithm was applied in final diagnosis reporting by the "AI+manual-check" method. The diagnosis of DR were classified into 0-4 stage. The 2-4 stage patients were classified into referral DR group. ResultsA total of 1 989 cases (94.5%, 1 989/2 104) were read by AI, of which 437 (88.1%, 437/496) and 1 552 (96.5%, 1 552/1 608) from the community and hospital, respectively. The reading rate of AI films from community sources was lower than that from hospital sources, and the difference was statistically significant (χ2=51.612, P<0.001). The main reasons for poor image quality in the community were small pupil (47.1%, 24/51), cataract (19.6%, 10/51), and cataract combined with small pupil (21.6%, 11/51). The total negative rate of DR was 62.4% (1 241/1 989); among them, the community and hospital sources were 84.2% and 56.3%, respectively, and the AI diagnosis negative rate of community source was higher than that of hospital, and the difference was statistically significant (χ2=113.108, P<0.001). AI diagnosis required referral to DR 20.2% (401/1 989). Among them, community and hospital sources were 6.4% and 24.0%, respectively. The rate of referral for DR for AI diagnosis from community sources was lower than that of hospitals, and the difference was statistically significant (χ2=65.655, P<0.001). There was a statistically significant difference in the composition ratio of patients with different stages of DR diagnosed by AI from different sources (χ2=13.435, P=0.001). Among them, community-derived patients were mainly DR without referral (52.2%, 36/69); hospital-derived patients were mainly DR requiring referral (54.9%, 373/679), and the detection rate of treated DR was higher (14.3%). The first rank of the order of the fundus lesions number automatically identified by AI was drusen (68.4%) and intraretinal hemorrhage (48.5%) in the communities and hospitals respectively. Conclusions It is more suitable for early and negative DR screening for its high non-referral DR detection rate in the community. Whilst referral DR were mainly found in hospital scenario.
Objective To observed and analyze the clinical features of patients with nonarteritic anterior ischemic optic neuropathy (NAION) causes of misdiagnosis. MethodsA retrospective case study. From November 2014 to July 2022, 49 NAION patients with 49 eyes diagnosed in Department of Ophthalmology, The First People’s Hospital of Lanzhou were included in the study. All patients were misdiagnosed with other eye diseases at first diagnosis. All eyes were examined by best corrected visual acuity (BCVA), relative afferent pupil defect (RAPD), orbital magnetic resonance imaging (MRI), visual field, optical coherence tomography (OCT), and graphic visual evoked potential (P-VEP). Fluorescein fundus angiography (FFA) was performed in 32 eyes. Clinical and MRI, visual field, P-VEP、FFA features of the patients were retrospectively analyzed. ResultsThere were 31 males and 18 females among the 49 patients. All cases were monocular. Age was (59.3±7.8) years. All of them complained of painless visual acuity loss or occlusion sensation in one eye. There were 12 (24.5%, 12/49) and 37 (75.6%, 37/49) cases with disease duration ＞2 months and ≤2 months, respectively. In 49 eyes, misdiagnosed as optic neuritis, normal tension glaucoma (NTG) or suspected glaucoma, optic disc vasculitis, cataract, diabetic retinopathy, traumatic optic neuropathy and toxic optic neuropathy were 28 (57.1%, 28/49), 11 (22.4%, 11/49), 5 (10.2%, 5/49), 2 (4.1%, 2/49), 1 (2.0%, 1/49), 1 (2.0%, 1/49), 1 (2.0%, 1/49) eyes. 24 (49.0%, 24/49), 16 (32.7%, 16/49) and 9 (18.4%, 9/49) eyes had BCVA＜0.1, 0.1-0.5 and＞0.5, respectively. RAPD was positive in 45 eyes (91.8%, 45/49). There were 37 (75.6%, 37/49) and 12 (24.5%, 12/49) eyes with and without optic disc edema, respectively. Bleeding was observed on and around the optic disc in 15 eyes (30.6%, 15/49). MRI examination showed no obvious abnormality in the optic nerve segments of all affected eyes. OCT showed an increase in retinal nerve fiber layer thickness (307.1±62.1) μm in 37 patients with optic disc edema. The visual field examination showed that 24 eyes (49.0%, 24/49) had typical lower visual field defect connected with the physiological blind spot and circumvented the central fixation point, 6 eyes (12.2%, 6/49) had limited visual field defect connected with the physiological blind spot, and 19 eyes (38.8%, 19/49) had diffuse visual field defect. By P-VEP examination, the amplitude of P100 wave decreased moderately to severely in all affected eyes. There were 24 eyes (49.0%, 24/49) with mild peak delay and 11 eyes (22.4%, 11/49) with moderate peak delay. In 32 eyes examined by FFA, the arteries had early peridisk limitation or diffuse delayed filling, and mid-course fluorescein leakage in the corresponding area. ConclusionsThe main symptoms of NAION patients are painless visual acuity loss in one eye or occlusion of vision. The main clinical features of NAION patients are visual field defect, retinal nerve fiber layer thickening and visual electrophysiological abnormalities. NAION patients with acute or subacute visual loss accompanied by optic disc edema and/or bleeding are often misdiagnosed as optic neuritis, optic neurovasculitis and other types of optic neuropathy. NAION patients with a disease course of ＞2 months are easily misdiagnosed as NTG.
Objective To report the clinical characteristics and treatment analysis of 3 cases of congenital ulnar collateral flexor contracture of the forearm and take a reference for clinic. Methods A total of 3 patients with congenital ulnar collateral flexor contracture of the forearm were admitted between February 2019 and August 2021. Two patients were male and 1 was female, and their ages were 16, 20, and 16 years, respectively. The disease durations were 8, 20, and 15 years, respectively. They all presented with flexion deformity of the proximal and distal interphalangeal joints of the middle, ring, and little fingers in the neutral or extended wrist position, and the deformity worsened in the extended wrist position. The total action motion (TAM) scores of 3 patients were 1 and the gradings were poor. The Carroll’s hand function evaluation scores were 48, 55, and 57, and the grip strength indexes were 72.8, 78.4, and 30.5. Preoperative CT of case 2 showed a bony protrusion of the flexor digitorum profundus tendon at the proximal end of the ulna; and MRI of case 3 showed that the ulnar flexor digitorum profundus presented as a uniform cord. After diagnosis, all patients were treated with operation to release the denatured tendon, and functional exercise was started early after operation. Results The incisions of 3 patients healed by first intention. Three patients were followed up for 12, 35, and 12 months, respectively. The hand function and the movement range of the joints significantly improved, but the grip strength did not significantly improve. At last follow-up, TAM scores were 3, 4, and 4, respectively, among which 2 cases were excellent and 1 case was good. Carroll’s hand function evaluation scores were 95, 90, and 94, and the grip strength indexes were 73.5, 81.3, and 34.2, respectively. ConclusionCongenital ulnar collateral flexor contracture is a rare clinical disease that should be distinguished from ischemic muscle contracture. The location of the contracture should be identified and appropriate surgical timing should be selected for surgical release. Active postoperative rehabilitation and functional exercise can achieve good hand function.
