Objective To evaluate the therapeutic effect of vitrectomy on bullous retinal detachment. Methods The clinical data of 7 patients (9 eyes) with bullous retinal detachment who had undergone vitrectomy due to useless photocoagulation were retrospectively analyzed. Bullous retinal detachment of the patients had been diagnosed by examination of slit-lamp microscope, three-mirror gonioscope, indirect ophthalmoscope, B-mode ultrasound, and fundus fluorescein angiography. All of the affected eyes underwent vitrectomy with closed triple incisions through the pars plana after release of subretinal liquid under the local anaesthesia. The cortex of vitreous body was taken out, and exsuction of subretinal liquid was carried out via retinal incision. Photocoagulation closed the incision and the effusion area of the retina, and intraocular filling matter was injected after exchange of air and liquid. The follow-up period lasted 3 months to 8 years with the average period of 47 months. Results Reattached retina was found in all of the affected eyes during the follow-up period. One eye underwent a second vitrectomy due to local retinal redetachment caused by a new retinal hole formed by the pull of pre-retinal proliferative membrane and a silicon vesicle entered the subretinal space, but the retina reattached after 1-year follow-up examination. The visual acuity impr oved in different degree after the operation in 8 eyes, but remained unchanged in 1 eye. Conclusion Vitrectomy for terminal bullous retinal detachment may promote the reattachment of retina safely and effectively, and save partial visual acuity of the affected eyes.

Objective To explore the association between triglyceride glucose-waist circumference (TyG-WC) index and the risk of stroke among the middle-aged and older people, and compare the differences among TyG-WC, triglyceride glucose (TyG), and waist circumference (WC) in the prediction of stroke. Methods The data of adults aged 45 years or older enrolled in the China Health and Retirement Longitudinal Study registry in 2011 were collected, and the endpoint was self-reported or physician-diagnosed new stroke event by 2015. According to the baseline TyG-WC tertile, individuals were divided into three groups: TyG-WC tertile 1, tertile 2, and tertile 3 groups. Multiple logistic regression analyses were performed to analyze the associations of TyG-WC, TyG, and WC with the risk of stroke. The area under the curve (AUC) of receiver operating characteristic (ROC) curve, integrated discrimination improvement (IDI) score, and net reclassification improvement (NRI) score were calculated to evaluate the predictive value of TyG-WC, TyG, and WC in stroke. Results A total of 5847 participants were finally included, with 1949 in each group. After 4 years of follow-up, there were 252 cases of new stroke. There was significant difference in the incidence of stroke among the three groups (TyG-WC tertile 1 group: 2.57%, TyG-WC tertile 2 group: 4.16%, TyG-WC tertile 3 group: 6.21%; P<0.05). The results of multiple logistic regression analyses showed that the risk of new stroke in the third tertile group of TyG-WC and WC was higher than that in the first tertile group, respectively [TyG-WC: odds ratio (OR)=1.465, 95% confidence interval (CI) (1.033, 2.078), P=0.032; WC: OR=1.717, 95%CI (1.190, 2.478), P=0.004], while TyG was not the risk factor of stroke (P>0.05). The ROC curve analysis showed that the AUC of WC (0.566) was slightly higher than that of TyG-WC (0.556) and TyG (0.527). The IDI of TyG-WC (0.25%) was slightly higher than that of WC (0.22%), and the both were higher than that of TyG (0.07%). The NRI of WC (25.04%) was slightly higher than that of TyG-WC (19.68%), and the both were high than that of TyG (12.02%). Conclusions Compared with TyG, higher TyG-WC and WC are associated with the increased risk of new stroke among the middle-aged and older people. The predictive value of TyG-WC and WC for the risk of new stroke in the middle-aged and elderly is similar, and is better than that of TyG.
ObjectiveTo explore the appropriate method of biventricular repair and analyze the risk factors for reoperation, by summarizing the 15-year treatment experience of biventricular repair for double outlet right ventricle with non-committed ventricular septal defect (DORVncVSD).MethodsClinical data of 162 consecutive patients with DORVncVSD who had biventricular repair from 2005 to 2019 in our center were retrospectively analyzed. The children were divided into two groups according to the path of intracardiac tunnel: 110 patients with ventricular septal defect rerouted to the aorta were recruited into a group A (75 males and 35 females aged 3.6±3.2 years); 52 patients with ventricular septal defect rerouted to the pulmonary artery were into a group B (30 males and 22 females aged 2.8±2.7 years). In order to establish a smooth intracardiac tunnel, enlargement of VSD, the resection of conus muscle and the transfer of tricuspid tendon or papillary muscle, etc were performed at the same time.ResultsIn the patients with biventricular repair, there were 9 (5.6%) early deaths and 6 (3.7%) early intracardiac baffle obstructions. During the follow-up of 7.5±7.0 years, and 8 (4.9%) late deaths occurred. The 1-year, 5-year, 10-year and 15-year survival rates of the group A were 92.7%, 91.1%, 91.1%, 85.4%, respectively and those of the group B were 92.2%, 85.2%, 85.2%, 85.2%, respectively. The difference between the two groups was not statistically significant (P=0.560). The follow-up results showed that 10 (6.2%) patients had late-onset intracardiac tunnel obstruction, and 8 patients underwent reoperation. There were more late-onset intracardiac tunnel obstruction patients and overall intracardiac tunnel obstruction patients in the group A than those in the group B (9 patients vs. 1 patient, P=0.017; 15 patients vs. 1 patient, P=0.001). No significant difference of early mortality and late mortality was noted for the group A (P=0.386) and the group B (P=0.223). Also it was noted that performing tricuspid valve operation at the same time in the group A had a significant impact to reduce the occurrence rate of intracardiac obstruction (1/46 vs. 15/64, P=0.004), without any tricuspid regurgitation or stenosis. The reoperation rate of patients with Rastelli after right ventricular outflow tract lesions was significantly higher than that of REV surgery and double root replacement surgery (5/14 vs. 0/38, P<0.001).ConclusionThe effect of biventricular repair for DORVncVSD is satisfactory. And concomitant tricuspid procedures can help reduce the occurrence of intracardiac obstructions. Reconstruction of right ventricular outflow tract with biological valved conduit is a risk factor for reoperation.
Objective To explore the clinical value, latest research progress, and clinical controversy of total neoadjuvant therapy (TNT) in locally advanced rectal cancer (LARC). Method We searched and reviewed on the latest literatures about studies of the clinical research of TNT in LARC. Results TNT could make the tumor downstage rapidly and improve the patients’ treatment compliance. In terms of organ preservation rate, 3-year disease-free survival and pathological complete remission rate, TNT had advantages and was a especial potential treatment strategy compared with traditional methods. Conclusions TNT decreases local recurrence rate and improves the long-term survival. For LARC patients with strong desire for organ preservation, TNT is a good treatment choice and has the value of clinical promotion.
Objective To construct a multi-dimensional risk assessment system and scale for the prevention and control risk of respiratory infectious diseases in general hospitals, and make evaluation and early warning. Methods Through the collection of relevant literature on the prevention and control of respiratory infectious diseases during the period from January 1st, 2020 to December 31st, 2022, the articles related to the risk assessment of respiratory infectious diseases such as severe acute respiratory syndrome, COVID-19 and influenza A (H1N1) were screened, and the Delphi method was used to evaluate the articles and establish an indicator system. The normalized weight and combined weight of each item were calculated by analytic hierarchy process. The technique for order preference by similarity to the ideal solution method was used to calculate the risk composite index of 38 clinical departments in a tertiary general hospital in Jiangxi Province in December 2022. Results A total of 16 experts were included, including 4 with senior titles, 8 with associate senior titles, and 4 with intermediate titles. After two rounds of Delphi consult, a total of 4 first-level indicators, 11 second-level indicators, and 38 third-level indicators of risk assessment for the prevention and control of respiratory infectious diseases were determined. The reliability and validity of the scale were good. The top three items with the largest combined weights in the scale were spread by aerosol, spread by respiratory droplet, and commonly used instruments (inspection instruments and monitoring equipment). After a comprehensive analysis on the 38 departments, the top 10 departments in the risk index were the departments of medical imaging, pediatrics, ultrasound, cardiac and vascular surgery, infection, emergency, respiratory and critical care, general medicine, otolaryngology and neck surgery, stomatology, and obstetrics. Conclusions This study constructed the risk assessment scale of respiratory infectious diseases in general hospitals, and the scale has good reliability and validity. The use of this scale for risk assessment of general hospitals can provide a theoretical basis for the risk characteristics of prevention and control of respiratory infectious diseases in general hospitals.
ObjectiveTo investigate the effectiveness on the distal radius deformity and bone defect after trauma by using Ilizarov external fixator.MethodsThe clinical data of 9 patients of post-traumatic distal radius deformity with bone defect treated by Ilizarov technique between January 2012 and December 2016 were retrospectively analyzed. There were 7 males and 2 females with an average age of 25.6 years (range, 11-46 years). Of the 9 cases, 4 were radial baseball hand deformity with large bone defect, 4 were short deformity of distal radius, 1 was distal radius deformity with radial deflection and pronation deformity, all with distal dislocation of the distant radial-ulnar joint. The time from injury to operation was 6 months to 6.2 years (mean, 1.5 years). The bone defect was 1.4-6.8 cm (mean, 3.6 cm). After complete debridement, the forearm was fixed with Ilizarov external fixator. At 7 days after operation, bone transport or bone lengthening was performed at the rate of 0.8-1 mm/d, 4 times a day, the deformity was slowly corrected and the bone defect was repaired. According to the loss of palmar tilt angle and ulnar tilt angle measured before operation, the position of distal radial articular surface was gradually adjusted in the course of moving or prolonging, so as to restore palmar tilt angle and ulnar tilt angle as far as possible.ResultsAll wounds healed by first intention and no leakage or rupture occurred. All the 9 patients were followed up 15-36 months (mean, 23 months). All the radius defects healed and the distal deformity was corrected, the healing time was 92.4-138.6 days (mean, 104.7 days); the external fixation index was 32.6-51.1 days/cm (mean, 40.2 days/cm). After 2 months of external fixator removal, the wrist joint flexion was (42.6±3.1)°, the wrist dorsum extension was (48.5±4.7)°, the palm inclination angle was (11.5±1.3)°, and the ulnar deviation angle was (21.2±3.7)°; the elbow flexion was (128.2±6.4)°, the elbow extension was (3.2±2.1)°, the forearm pronation was (71.5±4.3)°, and the forearm rotation was (38.2±6.5)°; the wrist and elbow joint extension and forearm rotation were significantly improved when compared with preoperative values (P<0.05). At last follow-up, wrist function was assessed according to Gartland-Werley standard, the results were excellent in 3 cases, good in 5 cases, and fair in 1 case. Four cases had pinhole infection, and were cured after anti inflammatory dressing change or replacement of needles; 3 cases did not heal at the bone junction, and were healed after bone grafting; 4 cases deviated from the radial force line, and the deformity was corrected after adjusting the needle.ConclusionIlizarov technique can correct deformity and reconstruct bone defect of the post-traumatic distal radius simultaneously, so it is a good method to treat this kind of disease.
ObjectiveTo assess mid-term outcomes of reduction ascending aortoplasty (RAA) in adult patients undergoing aortic valve replacement (AVR).MethodsWe retrospecctively analyzed clinical data of 30 adult patients with aortic valve diseases and ascending aortic dilatation in Fuwai Hospital from 2010 to 2019. There were 20 males and 10 females with an age of 38-72 (55.73±9.95) years. All patients received AVR+RAA using the wedge resection technique. Ascending aorta diameter (AAD) was measured by echocardiography or CT scan preoperatively and postoperatively.ResultsThere was no perioperative death. The mean preoperative and postoperative AAD in all patients were 48.23±3.69 mm and 37.60±5.02 mm, respectively. And the mean AAD of follow-up was 40.53±4.65 mm. There was a statistical difference in AAD between preoperation and postoperation, postoperation and final follow-up, preoperation and final follow-up. The median follow-up time was 28.50 (12-114) months. The median rate of increase in AAD postoperatively was 0.76 mm per year. And the rate of increase was ≥3 mm per year in 5 patients, while ≥5 mm per year in 4 patients with indications for reoperation. ConclusionMid-term outcomes of RAA in adult patients undergoing aortic valve replacement using the wedge resection technique are satisfying and encouraging. However, some patients still need surgical re-intervention.
Objective To review the research progress of pubic symphysis diastasis and provide effective reference for orthopedic surgeons in the diagnosis and treatment of pubic symphysis diastasis. MethodsThe anatomy, injury mechanism, treatment, and other aspects of pubic symphysis diastasis were summarized and analyzed by reviewing the relevant research literature at domestically and internationally in recent years. ResultsThe incidence of pubic symphysis diastasis is high in pelvic fractures, which is caused by the injury of the ligaments and fibrocartilage disc around the pubic symphysis by external force. The treatment plan should be individualized according to the pelvic stability and the needs of patients, aiming to restore the stability and integrity of the pelvis and improve the quality of life of patients after surgery. ConclusionAt present, the research on pubic symphysis diastasis still needs to be improved. In the future, high-quality, multi-center, and large-sample studies are of great significance for the selection of treatment methods and the evaluation of effectiveness for patients with pubic symphysis diastasis.
Objective To reveal the significance of D2-40/CK19 dual immunohistochemistry for micrometastasis of peripancreatic neural plexus in patients with pancreatic cancer. Methods Between January 2006 and January 2007, 44 patients with pancreatic duct adenocarcinoma underwent extended radical resection. Conventional hematoxylin/eosin staining and double immunohistochemical staining using CK19 and D2-40 were used to determine peripancreatic neural invasion and lymphatic vessel invasion (LVI) in peripancreatic neural plexus tissues. Results D2-40 immunohistochemistry showed brown-yellow tube-like lymph vessels. The lymph vessel of peripancreatic nerve plexus followed vascular and perineurium, and the lymph vessel adjacent to peripheral nerve fascicles owned tube-like structure. CK19 immunohistochemistry showed cytoplasm of pancreatic cancer cell was red. The LVI was observed in lymphatic capillaries. Peripancreatic neural plexus invasion was found in 30 cases (68.2%), tumor cell invading presented in lymph vessels of peripancreatic neural plexus in 21 patients (47.7%) with pancreatic cancer. The peripancreatic neural plexus invasion was associated with LVI (P=0.003). The plexus of pancreatic capitalis and celiac plexus were respectively confirmed to be the spot with the highest lymphatic vessel density and the maximal incidence of neural plexus invasion simultaneously. Conclusions Patients with pancreatic cancer should be given the opportunity of radical operation combining related peripancreatic neural plexus as far as possible. The dual immunohistochemical staining with anti-CK19 and anti-D2-40 monoclonal antibodies should be a new method in research of perineural invasion of pancreatic cancer, exhibiting both the pancreatic cancer cells and lymph vessels clearly and distinctly.
