Objective To explore the value of laparoscope in the treatment of biliary leak after laparoscopic cholecystectomy (LC). Methods 16 cases of biliary leak after LC from August 1996 to May 2001 were reviewed retrospectively. Results 14 patients with biliary leak without bile duct injury were operated on under laparoscope. 2 patients with biliary leak and bile duct injury were converted to open operation. Conclusions Laparoscope can confirm reasons of biliary leak and shorten hospitalization time of patients with biliary leak without bile duct injury.

Objective: To examine the frequency and timing of inpatient engagement in meaningful activities within rehabilitation (within and outside of structured therapy times) and determine the associations between activity type, goal awareness, and patient affect. Methods: This prospective observational study performed behavioral mapping in a 42-bed inpatient brain injury rehabilitation unit by recording patient activity every 15 minutes (total 42 hours). The participants were randomly selected rehabilitation inpatients with acquired brain injury; all completed the study. The main outcome measures included patient demographics, observation of activity, participation, goal awareness, and affect. Results: The inpatients spent 61% of the therapeutic day (8:30 to 16:30) in their single room and were alone 49% of the time. They were physically socially inactive for 76% and 74% of their awake time, respectively, with neutral affect observed for about half of this time. Goal-related activities were recorded for only 25% of the inpatients’ awake time. The odds of physical activity were 10.3-fold higher among in patients receiving support to address their goals within their rehabilitation program (odds ratio=10.3; 95% confidence interval, 5.02–21.16). Conclusion Inpatients in a mixed brain injury rehabilitation unit spent a large amount of their awake hours inactive and only participated in goal-related activities for a quarter of their awake time. Rehabilitation models that increase opportunities for physical, cognitive, and social activities outside of allied health sessions are recommended to increase overall activity levels during inpatient rehabilitation.

Objective To investigate the application value of enhanced recovery after surgery with no gastrointestinal decompression tube and with early postoperative oral feeding in minimally invasive radical resectionof esophageal cancer.Methods The retrospective cohort study was conducted.The clinicopathological data of 126 patients who underwent minimally invasive McKeown surgery in the General Hospital of Southern Theatre Command of PLA between March 2016 and October 2017 were collected.There were 80 males and 46 females,aged from 52 to 82 years,with an average age of 64 years.Of 126 patients,82 undergoing "li's anastomosis" with no gastrointestinal decompression tube and receiving early postoperative oral feeding were allocated into non-tube no fasting group,and 44 undergoing end-to-side gastroesophageal anastomosis with tubular stapler,conventionally indwelling gastrointestinal decompression tube,and beginning oral feeding at 1 week after surgery were allocated into traditional treatment group.Observation indicators:(1) surgical and postoperative recovery situations;(2) results of pathological examination;(3) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative tumor recurrence and metastasis up to October 2018.Measurement data with normal distribution were represented as Mean ± SD,and comparison between groups was analyzed using independent sample t test.Measurement data with skewed distribution were expressed as M (range),and comparison between groups was analyzed by rank sum test.Count data were described as absolute number or percentage,and comparison between groups was analyzed using chi-square test.Ordinal data were analyzed by rank sum test.Results (1) Surgical and postoperative recovery situations:patients in the two groups underwent minimally invasive McKeown surgery successfully.Operation time,volume of intraoperative blood loss,incidence of anastomotic fistula,incidence of pulmonary complications,and duration of postoperative hospital stay were respectively (326±41) minutes,(225±96) ml,7.3 ％ (6/82),24.4％ (20/82),and 10 days (range,6-90 days) in the non-tube no fasting group and (317± 37) minutes,(214 ± 66) mL,9.1％ (4/44),20.5％ (9/44),and 14 days (range,10-42 days) in the traditional treatment group;there was a statistically significant difference in duration of postoperative hospital stay between the two groups (Z =-7.129,P ＜ 0.05) and no statistically significant difference in operation time,volume of intraoperative blood loss,incidence of anastomotic fistula,and incidence of pulmonary complications between the two groups (t =1.311,0.703,x2 =0.000,0.077,P＞0.05).(2) Results of pathological examination:the number of lymph node dissected,cases in postoperative TNM stage Ⅰ,Ⅱ and Ⅲ were respectively 27±5,12,55,15 in the non-tube no fasting group and 26±5,9,28,7 in the traditional treatment group,with no statistically significant difference between the two groups (t =0.549,Z =-0.747,P＞0.05).(3) Follow-up:of 126 patients,116 were followed up for 12-31 months,with a median time of 20 months,including 76 in the non-tube no fasting group and 40 in the traditional treatment group.During the follow-up,no tumor recurrence or metastasis was found in the 116 patients.Conclusion The enhanced recovery after surgery with no gastrointestinal decompression tube and with early postoperative oral feeding is safe and feasible in the McKeown surgery,which can significantly shorten the postoperative hospitalization time compared with the traditional treatment.

OBJECTIVE:To investigate the status quo of knowledge-attitude-practice(KAP)of medication in residents,and to explore potential risk factors that may affect medication. METHODS:By approximate random sampling,online(wenjuanxing)and offline method (5 communities of Chengdu city) were used to collect general information (gender, age, monthly income, residence,medical insurance,education level,working condition,occupation)of the residents aged 19 year-old above and conduct KAP investigation during Jul.-Aug. 2017. Multiple linear regression analysis was used to analyze the influence of residents'general information on KAP. RESULTS:A total of 517 online and offline valid questionnaires were obtained, including 200 offline questionnaires were sent out and 184 valid questionnaires were returned with recovery rate of 92％. Average scores of medication knowledge,attitude and practice were (71.4 ± 32.3),(33.7 ± 14.0),(60.7 ± 19.4),which all reached"good"in the evaluation standard of questionnaire results. The results of multiple linear regression showed that elderly and low education level were the significant influential factors of residents'lack of medication knowledge. The male,elderly,low income and low education level were the influential factors of poor drug use behavior. The residents with poor attitudes towards medication were low income and low educated population. CONCLUSIONS:The average risk of residents'medication in China is low,but it is still necessary to strengthen medication education for special people. It is requisite to focus on the elderly,the low education level,the low income population and the male residents.

Objective To investigate the application prospect of the most extensive genome engineering pig internationally in preclinical xenotransplantation. Methods Porcine endogenous retrovirus (PERV) knockout combined with 3 major heterologous antigen gene knockouts and 9 humanized genes for inhibition of complement activation, regulation of coagulation disorders, anti-inflammatory and anti-phagocytosis were transferred into a pig (PERV-KO/3-KO/9-TG) as a donor, and the heart, liver and kidney were obtained and transplanted to 3 Rhesus macaque recipients respectively to establish a preclinical research model of pig-to-Rhesus macaque xenotransplantation. The functional status of xenografts after blood flow reconstruction was observed and the survival of recipients was summarized. The hemodynamics of xenografts were monitored. The change of hematological indexes of each recipient was compared. The histopathological manifestation of xenografts was observed. Results After the blood flow was reconstructed, all xenografts showed ruddy color, soft texture and good perfusion. The transplant heart, liver and kidney showed full arterial and venous blood flow and good perfusion at 1 d after operation. The postoperative survival time of heart, liver, and kidney transplant recipients was 7, 26, and 1 d, respectively. The levels of creatine kinase, creatine kinase isoenzyme, and lactate dehydrogenase increased in heart transplant recipient at 1 d after operation, and gradually recovered to near normal levels at 6 d after operation. All indexes increased sharply at 7 d after operation. The level of aspartate aminotransferase increased in liver transplant recipients at 2 d after operation, and the alanine aminotransferase basically returned to normal at 10 d after operation, but the total bilirubin continued to increase. Both aspartate aminotransferase and alanine aminotransferase increased at 12 d after operation, and reached a peak at 15 d after operation. The kidney transplant recipient developed mild proteinuria at 1 d after operation, and died of sudden severe arrhythmia. Histopathology showed that the tissue structure of cardiac and renal xenografts was close to normal, and liver xenografts presented with patchy necrosis, the liver tissue structure was disordered, accompanied by inflammatory damage, interstitial hemorrhage and thrombotic microangiopathy. Conclusions PERV-KO/3-KO/9-TG pig shows advantages in overcoming hyperacute rejection, mitigating humoral rejection and coagulation dysregulation. However, whether it can be used as potential donor for clinical xenotransplantation needs further evaluation.

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

OBJECTIVE To evaluate the effectiveness of Polyene phosphatidylcholine capsules （PPC） as adjuvant therapy for chronic hepatitis B （CHB）. METHODS Retrospective data were collected from the patients diagnosed with CHB， treated with hepatoprotective drugs combined with antiviral drugs or antiviral drugs alone， and underwent long-term follow-up in the outpatient department of Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital from January 1， 2017 to December 31， 2022. After balancing confounding factors through propensity score matching， the effectiveness of PPC combined with antiviral therapy versus antiviral therapy alone （PPC+antiviral group versus antiviral group） and PPC+Diammonium glycyrrhizinate enteric- coated capsules （DGC） combined with antiviral therapy versus DGC combined with antiviral therapy （PPC+DGC+antiviral group versus DGC+antiviral group） as therapy for CHB were compared under real medical conditions. RESULTS Totally 382 patients with CHB who received hepatoprotective agents based on antiviral therapy （221， 63 and 98 patients who received DGC， PPC and combination therapy， respectively） and 400 patients who received antiviral therapy alone were ultimately included. After propensity score matching， there were 47 patients each in the PPC+antiviral group and the antiviral group， respectively； after treatment， the alanine transaminase （ALT） levels in the PPC+antiviral group were significantly reduced compared to before treatment and the antiviral group at the same time （P＜0.05）， while there was no statistically significant difference in the ALT normalization rate between the two groups （P＞0.05）. There were 74 patients each in the PPC+DGC+antiviral group and the DGC+antiviral group， respectively； after treatment， the ALT levels of patients in both groups were significantly reduced compared to before treatment， the ALT levels of PPC+DGC+antiviral group were significantly lower than those in the DGC+antiviral group at the same time， and the ALT normalization rate was significantly higher in the PPC+DGC+antiviral group than that in the DGC+antiviral group （P＜0.05）. CONCLUSIONS Based on using antiviral drugs to treat CHB， adjuvant therapy combined with PPC has a significant advantage in reducing liver enzymes； in addition， compared with the DGC combined antiviral regimen， the dual hepatoprotective drug of DGC and PPC combined with an antiviral regimen has better effects on liver protection and reduction of liver enzymes.
