Methods Ninty patients scheduled for laparoscopic cholecystectomy between october 2009 to Jannary 2010 were randomly assigned to three groups (n=30). Group K was administrated with 0. 5 mg/kg ketamine intravenously before skin incision, and Group K1 were administrated with 0. 5 mg/kg ketamine intravenously before abdominal closure, while Group C received nothing. The recovery and the side effects were recorded, the VAS at two, four, eight and 24 hours after surgery, and the use of anodyne were recorded. Results The incidence of restlessness in Groups K and K1 was remarkably lower than that of Group C (Plt;0. 05). The analgesic effects two, four, eight and 24 hours after surgery were obviously better in group K than those of Group C and Group K1 (Plt;0. 05). Conclusion Ketamine can produce preemptive analgesia to relieve remifentanil-induced acute pain, and it would not increase incidence of side effects.
目的 探讨孤立肾肾结石经皮肾镜取石（PCNL）术并发感染性休克的护理。 方法 回顾性分析2010年3月－2012年10月5例孤立肾肾结石患者行PCNL术后并发感染性休克的临床资料，对患者术后出现的休克及时补足血容量，使用有效的抗生素，早期足量应用激素、血管活性药物，同时加强心理疏导、健康教育等护理措施。 结果 5例患者体温均在3 d内降至正常；血管活性药物平均使用时间为1.8 d （2～4 d）；1例因血氧饱和度＜80%，血压＜85/50 mm Hg（1 mm Hg=0.133 kPa）转往重症监护病房行呼吸机辅助呼吸2 d后呼吸循环功能改善；另1例同时出现少尿无尿，及时行血液透析，第4天尿量逐渐恢复；5例患者均痊愈出院。 结论 感染性休克是PCNL术后最危险的并发症之一，对其采取积极预防、及早发现、及时有效的治疗和护理等措施，可有效促进患者康复。

Methods We retrospectively analyzed the MSCT manifestations of 32 cases of GIST confirmed by operation and pathology between March 2000 and October 2010. Comparative study was then carried out between MSCT manifestations and patho-physiological risks. Results Of the 32 GIST lesions, 15 presented with high biological risks, six moderate risks, seven low risks and four very low risks. The MSCT results manifested the following main features. Exophytic growth was predominating; Most lesions were with well-defined margins, and were rotund or lobular in shape with homogeneous or heterogeneous density. Three lesions manifested calcification. The enhancement degree of GIST in portal vein phase was more obvious than in arterial phase. There was no metastasis to local lymph nodes. Hepatic metastasis occurred in four cases, one of which was accompanied with anterior abdominal wall metastasis. Of the 15 lesions with maximal diameter longer than 5 cm, MSCT showed obvious cystic changes, necrosis or hemorrhage within the mass most of which was in heterogeneous density, and heterogeneous enhancement; Eleven out of the 15 lesions were at high risk. Among the 17 lesions with maximal diameter shorter than 5 cm, MSCT showed homogeneous enhancement, and 13 of them were at moderate risk or below. Conclusion The MSCT imaging of GIST manifests some certain characteristics. It is valuable in locating the lesion precisely, estimating the risk level of the tumor, and postoperative follow-up for patients with GIST.
Objective To investigate the prevalence of anxiety and depression in patients with epilepsy (PWE) in West China, and to explore the related risk factors. Methods The Chinese version of Generalized Anxiety Disorder (GAD)-7 and Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) scales were used to evaluate the anxiety and depression in 176 PWE patients between December 2016 and February 2017. Univariate analysis was used to screen the factors that may cause anxiety and depression in PWE, and then logistic regression analysis was performed on the possible risk factors. Results In the 176 PWE, about 27.3% had anxiety, and about 28.4% had depression. Multivariate logistic regression analysis showed that seizure occurrence in the recent six months [odds ratio (OR)=3.481, 95% confidence interval (CI) (1.292, 9.380),P=0.014], seizure occurring more than once in a month [OR=3.231, 95%CI (1.468, 7.111),P=0.004], and focal seizures with conscious disorders [OR=2.416, 95%CI (1.082, 5.397),P=0.031] were risk factors for anxiety in PWE. Unmarried status [OR=0.428, 95%CI (0.195, 0.940),P=0.035], seizure occurring more than once in a month [OR=2.685, 95%CI (1.206, 5.979),P=0.016], focal seizures with conscious disorders [OR=2.541, 95%CI (1.112, 5.808),P=0.027] and seizure occurrence in the last six months [OR=7.582, 95%CI (2.416, 23.794),P=0.001] were risk factors for depression in PWE. Conclusions Anxiety and depression are common comorbidities in PWE. For patients with risk factors, early identification and intervention should be performed.
Objective To explore the strategies of improving the teaching quality of complete physical examination in diagnostics. Methods A total of 314 medical students' surveys relating to contents and skills of complete physical examination in Diagnostics were accomplished. Problems in the teaching quality of the complete physical examination were selected and countermeasures were determined by analyzing scores and performance of students. Results Among 192 items in a complete physical examination, students mastered poorly in 77 (40.1%) items, and especially poorly in 14. Skills of a comprehensive physical examination, including examination without repetition, inversion, omission and skills of palpation and percussion, were difficult to acquire. Conclusion It is helpful to improve the teaching quality of a complete physical examination by analyzing the problems in the physical examination to formulate the teaching objectives and optimize teaching methods.
Objective To explore the relationship of self-efficacy and coping styles with parenting styles in patients with schizophrenia, and provide the theory and practical basis for family-interventions of rehabilitation of patients with schizophrenia. Methods From January to June 2015, General Self- Efficacy Scale, Simplified Coping Style Questionnaire and Egma Minnen av Bardndosnauppforstran were used to evaluate 60 inpatients with schizophrenia and in good rehabilitation in a grade A tertiary general hospital. Results The scores of self-efficacy, parental emotional warmth and father’s over protection were lower in patients with schizophrenia than the norms (P<0.01). The scores of parental punishment and rejection and father’s over intervention were higher in patients with schizophrenia than the norms (P<0.01). In patients with schizophrenia, the active coping domain was positively correlated to parental emotion warmth (P<0.05); the negative coping domain was positively correlated to parental rejection, father’s over protection and mother’s over intervention (P<0.05); self-efficacy was positively correlated to father’s emotion warmth and preference of parents (P<0.05). Conclusions Active family-interventions is important in the rehabilitation of patients with schizophrenia. The parents should be instructed to correctly educate the children, to improve the patients’ general self-efficacy, and help the patients successfully solve the problem with good coping style.
ObjectiveTo systematically review the influence of dexmedetomidine on early postoperative cognitive dysfunction (POCD) and serum inflammatory factors in elderly patients.MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases from inception to April 2017, to collect randomized controlled trials (RCTs) about dexmedetomidine for early POCD in elderly patients. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 23 RCTs, including 2 026 patients were enrolled. The results of meta-analysis showed that, the incidence of POCD in the dexmedetomidine group was lower than that in the control group (the first day: RR=0.40, 95%CI 0.30 to 0.53, P<0.000 01; the third day: RR=0.33, 95%CI 0.23 to 0.48,P<0.000 01; the seventh day: RR=0.42, 95%CI 0.22 to 0.78,P=0.006). Meanwhile, compared with the control group, the dexmedetomidine group significantly decreased the serum levels of TNF-α (immediately after operation: MD=–5.43, 95%CI –7.44 to –3.42, P<0.000 01; 1 h after operation: MD=–4.64, 95%CI –6.92 to –2.36,P<0.000 1; 24 h after operation: MD=–3.27, 95%CI –4.92 to –1.63,P<0.000 1) and IL-6 (immediately after operation: MD=–30.69, 95%CI –41.39 to –20.00,P<0.000 01; 1h after operation: MD=–20.84, 95%CI –28.87 to –12.80,P<0.000 01; 24 h after operation: MD=–13.42, 95%CI –19.90 to –6.94,P<0.000 1).ConclusionCurrent evidence indicates that dexmedetomidine could relief early POCD in elderly patients, in which the reduction of serum inflammatory factors alleviate inflammation response may play a vital role. Due to the limited quality and quantity of included studies, more high quality RCTs are required to verify the above conclusion.
ObjectiveTo summarize the application of magnetic resonance imaging (MRI) in the evaluation of pancreatic exocrine function.MethodIn this paper, we reviewed and summarized the related literatures about the application of MRI in the field of pancreatic exocrine function evaluation in recent years.ResultsA variety of MRI techniques could be used to detect the pancreatic exocrine function. In addition to conventional MRI techniques, there were also MRI stimulated by pancreatic secretions, cine (dynamic) cholangiopancreatography based on space selective reverse recovery pulse, and so on.ConclusionThe new MRI techniques have potential for semi-quantitative and quantitative evaluation of pancreatic exocrine function.
ObjectiveTo systematically evaluate the effect of high-flow nasal cannula in immunocompromised patients with acute respiratory failure.MethodsRandomized controlled trials (RCT) or cohort studies on the efficacy of high-flow oxygen therapy in immunocompromised patients with acute respiratory failure were reviewed by computer in PubMed, EMBASE, Cochrane Library, and China Knowledge Network, Wanfang and VIP databases. The group used HFNC and the control group used a mask or a nasal catheter to give oxygen-based conventional oxygen therapy (COT) or noninvasive ventilation (NIV). Two investigators conducted quality assessments and data extractions based on the Cochrane Collaboration Risk Assessment Manual and the Newcastle-Ottawa Scale. Meta analysis was performed using RevMan 5.3 software. The main outcome measures included tracheal intubation rate, and intensive care unit (ICU) mortality. The secondary outcomes included ICU hospitalization time.ResultsThe study included 13 articles (4 RCTs, 9 cohort studies), a total of 1133 subjects, with 583 in the HFNC group and 550 in the control group (280 in the COT and 270 in the NIV). Meta-analysis showed that HFNC was significantly different from COT in reducing tracheal intubation rate in immunocompromised patients with respiratory failure (OR=0.49, 95%CI 0.33 - 0.72, P=0.0003), but no statistical significance compared with NIV (OR=0.73, 95%CI 0.52 - 1.02, P=0.07); two-combination analysis showed that HFNC had a significant advantage in reducing tracheal intubation rate compared with COT/NIV (combined OR=0.61, 95%CI 0.47 - 0.79, P=0.0002). In terms of ICU mortality, there was a statistically significant difference between HFNC and COT (OR=0.59, 95%CI 0.35 - 1.01, P=0.05) or NIV (OR=0.63, 95%CI 0.44 - 0.91, P=0.01). The results of the two subcombinations and analysis did not change (combined OR=0.62, 95%CI 0.46 - 0.83, P=0.002). In terms of ICU hospital stay, there was no statistically significant difference between HFNC and COT (MD=−4.52, 95%CI −9.43 - 0.39, P=0.07), but the difference was statistically significant compared with NIV (MD=−1.46, 95%CI −2.41 - −0.51, P =0.003); the two sub-combinations and analysis results showed significant difference (combined MD=−3.41, 95%CI −6.16 - −0.66, P=0.01). According to different research types, after subgroup analysis, the analysis results were not different from the combined results. Sensitivity analysis revealed that HFNC could significantly reduce the patient's ICU hospital stay compared with the control group oxygen therapy. The results of the funnel chart analysis show that there were publication offsets in the studies on tracheal intubation rate and ICU mortality included in the literature; studies on ICU hospital stays had a smaller publication offset.ConclusionsCompared with COT, HFNC can reduce the tracheal intubation rate of patients, but there is no significant difference compared with NIV; HFNC can reduce the ICU mortality of patients compared with COT/NIV. However, due to the high heterogeneity between the studies, whether HFNC can reduce ICU hospital stay remains to be further explored.
Objective To summarize the clinical characteristics of pneumocystis pneumonia (PCP) secondary to interstitial lung disease (ILD) to improve the prophylaxis and management level of clinicians. Methods The clinical data of 50 patients with PCP secondary to ILD in the Department of Respiratory and Critical Care Medicine of Nanjing Drum Tower Hospital from January 2015 to December 2022 were collected. SPSS 26.0 software was used for statistical analysis. Results A total of 50 patients with PCP secondary to ILD were screened. Among the 50 patients, there were 23 males and 27 females, with a median age of 64 years old. Forty-eight cases (96%) had a history of glucocorticoid therapy with the median duration of 3 months; 31 (77.5%, 31/40) cases developed PCP in the first 6 months after glucocorticoid therapy; 34 cases had a history of glucocorticoid and immunosuppressants at the same time. None of the 50 ILD patients used drugs for PCP prophylaxis before developing PCP. The major clinical manifestations of PCP secondary to ILD were worse cough and shortness of breath or fever. Laboratory results showed 38 cases (76.0%) had peripheral blood total lymphocyte count <200/µL, 27 cases (54.0%) had CD4+ T cell count <200/µL, 34 cases (68.0%) had CD4+ T cell count <300/µL, 37 cases (74.0%) had CD3+ T cell count <750/µL, 34 cases (68.0%) had β-D-glucan test >200 pg/mL, 35 cases (70.0%) had lactic dehydrogenase > 350 U/L and 41 cases (82.0%) had type Ⅰ respiratory failure. High resolution computed tomography showed added ground-glass opacity and consolidation on the basis of the original ILD. Thirty-six cases were detected the Pneumocystis jirovecii by metagenomic next-generation sequencing with broncho-alveolar lavage fluid as the main source, and 2 cases by smear microscopy. All patients were treated with trimethoprim-sulfamethoxazole. After treatment, 29 cases were discharged with a better health condition, 10 cased died, and 11 cases left hospital voluntarily because of treatment failure or disease deterioration. Conclusions After the use of glucocorticoid and immunosuppressants, ILD patients are susceptible to life-threatening PCP. It is particularly important to make an early diagnosis. Attention should be paid to integrate the symptoms, levels of peripheral blood lymphocyte count, β-D-glucan test, lactic dehydrogenase and imaging findings to make an overall consideration. It is suggested to perform next-generation sequencing with broncho-alveolar lavage fluid at an early stage when patients can tolerate fiberoptic bronchoscopy to avoid misdiagnosis and missed diagnosis. ILD patients often develop PCP in the first 6 months after using glucocorticoid and immunosuppressants. During follow-up, peripheral blood CD4+ and CD3+ T cell count should regularly be monitored so as to timely prevent PCP.
