Objective To study the use of early bile duct to bile duct end-to-end(side) anastomosis for extrahepatic bile duct injuries.Methods The clinical data of 25 patients with extrahepatic bile duct injuries with early bile duct to bile duct end-to-end(side) anastomosis were retrospectively analyzed.Results Bile duct injuries happened in laparoscopic cholecystectomy (n=17),laparoscopic exploration of common bile duct (n=1),laparotomy (n=5),and knife wound (n=2).All of the repairs were successfully carried out.Except for one patient who was lost to follow-up,the other patients were followed for over 2 years.There was no bile duct stenosis.One patient died after 5 months of repair in other hospital because of a recurrent bile duct calculus.Conclusions Early bile duct to bile duct end-to-end(side) anastomosis had a good long-term results.The operation needs to be done by a good surgeon or supervised by an experienced specialist in biliary surgery.A prolonged period of T tube stenting is a prerequisite for success.

Objective To investigate the influencing factors for post-discharge treatment compliance of patients with multidrug-resistant tuberculosis (MDR-TB).Methods MDR-TB patients who were hospitalized in a tubercu-losis hospital between November 2011 and January 2013 were chosen,post-discharge follow-up was conducted regu-larly through telephone call.Medicine-taking and re-examination of patients was inquired,factors influencing pa-tients’treatment compliance were analyzed.Results 299 patients were included in the study,the total treatment compliance rate was 81 .94% (n=245);249(83.28%)patients regularly took medicine,50(16.72%)didn’t regu-larly take medicine;254 (84.95%)were re-examined on time,45 (15.05%)were not re-examined on time;37 (12.37%)discontinued treatment,260 (86.96%)continuously treated till the survey deadline.Univariate analysis revealed that treatment compliance (including regular medication rate,timely re-examination rate,interrupted treat-ment rate,and total compliance rate)was significantly different among MDR-TB patients of different ages,education levels,treatment time,and with or without adverse reactions(all P <0.05 ).Logistic regression analysis revealed that treatment compliance of MDR-TB patients was negatively correlated with treatment time(β=-1 .47,Wald χ2=24.28,P <0.05)and adverse reactions(β=-2.02,Waldχ2 =24.24,P <0.05 ),while positively correlated with education levels(β=0.79,Wald χ2 =6.50,p <0.05 ).Conclusion Prolonged treatment time and adverse reactions can reduce the treatment compliance of MDR-TB patients,the higher education levels of MDR-TB patients have, the better treatment compliance they implement.

Objective To investigate the prevalence of tuberculosis (TB) in human immunodeficiency virus (HIV) positive population and explore its influencing factors.Methods Cluster sampling was used,continuous 205 cases who were diagnosed as HIV positive from December 16,2002 to June 30,2012 in Zhuhui district and Yanfeng district of Hunan province and could be followed up and traced were enrolled in the study.All patients were screened after informed content through questionnaire,sputum smear examination,chest X-ray examination,liquid culture (BACTECTM MGITTM 960 operating system),mycobacterium species identification (for liquid culture positive) and CD4 testing.Univariate and multivariate analyses were conducted to identify the impacts of different sex,age,and TB suspect syndromes,etc.Results Of 205 cases,19 were diagnosed as tuberculosis.The rate of TB/HIV was 9.3％.Univariate analysis showed that age,annual household net income,being acquired immunodeficiency syndrome (AIDS) patients and with TB suspect syndromes had significant impacts on tuberculosis combining (P ＜ 0.05).While multivariate analysis showed that age (OR =1.443) and TB suspect syndromes (OR =3.124) were risk factors influencing TB combining in people living with HIV (PLHIVs).Conclusions TB prevalence in HIV positive population was higher in Zhuhui district and Yanfeng,those aged and with TB suspect syndromes cases had higher risk to develop tuberculosis.TB screening should be reinforced in HIV positive population.

Objective To analyse the effect of mobilization and collection's time of peripheral blood stem cells(PBSC) from 8 cases of healthy donors. Methods The 10 donors were studied by self-control design.The number of aphereses was two times every donors. Healthy donors received rhG-CSF according to two different PBSC collection starting time: group 1:PBSC collection was starts 2 hours(2 h) after the fourth day or the fifth day of rhG-CSF. group 2:PBSC collection was starts 4 hours(4 h) after the fourth day or the fifth day of rhG-CSF.(The first dose of rhG-CSF was given on day 1, considering day 0 as the day before starting mobilization). In this study we have compared with two groups of apheresis product. Results The MNC count was significantly higher for donors 4 h collection (groups 2) then 2 h. ( groups 1)(P

Objective:To analyze the factors affecting the disappearance time of airway necrosis and repair time of airway scar stenosis in patients with ulceration necrosis tracheobronchial tuberculosis (TBTB Ⅱ) after standardized chemotherapy and bronchoscopic intervention.Methods:The clinical data of 222 TBTB Ⅱ patients admitted to Hunan Chest Hospital from January 2015 to December 2018 were collected, bronchoscopic interventional treatment was performed on time. The texture, blockage of lumen, granulation proliferation, airway stenosis of TBTB patients before treatment, the disappearance time of airway dead objects, scar repair time and stenosis degree after treatment were followed up. The disappearance time of airway necrosis and repair time of airway scar stenosis and its influencing factors were recorded and analyzed.Results:In 222 patients, 508 ulceration necrosis airway lesions were found under bronchoscopy, with a median of 2(1-6); 170(76.6%) cases of airway lesions had different degrees of stenosis before treatment. 79(35.6%) patients had tough necrosis, and 86(38.7%) patients had necrosis blocking the lumen; 132(59.5%) patients had granulomatosis. The disappearance time of airway necrosis after treatment was 1 to 32 weeks, and M( Q1, Q3) was 6(3, 9) weeks; the repair time of airway scar stenosis was 2 to 73 weeks, and M( Q1, Q3) was 14(10, 19) weeks; after treatment, there were 90.5%(201/222) patients with different degrees of scarring in the airways. Cox multiple analysis showed that the risk factor for the disappearance time of airway necrosis was tough tough necrosis ( HR=1.52, 95% CI: 1.10-2.10); the risk factor for the repair time of airway scar stenosis was the disappearance time of airway necrosis 6-9 weeks ( HR=2.73, 95% CI: 1.84-4.05). Conclusions:90.5% of patients with type Ⅱ TBTB developed airway scar stenosis after treatment. The median time for the disappearance of airway necrosis was 6 weeks, and the median time for the repair time of airway scar stenosis was 14 weeks. In the interventional process, attention should be paid to the removal of tough necrosis and the efficiency of necrosis removal to reduce the risk of airway scar stenosis.

Objective:To observe and compare the changes of pulmonary function in patients with pulmonary tuberculosis regular treatment for 3 months.Methods:From April 2018 to June 2019, 500 tuberculosis patients who received regular anti tuberculosis treatment in our hospital were selected.The pulmonary function of patients with pulmonary tuberculosis was measured before treatment and at the end of three months; the results of pulmonary ventilation function, lung volume, diffusing capacity, and the value of forced vital capacity (FVC), maximum expiratory volume in 1 second (FEV 1), maximum expiratory volume in 1 second/forced vital capacity (FEV 1/FVC), total lung volume (TLC), residual volume (RV), carbon monoxide diffusing capacity (D LCO) were compared. Results:252 patients with pulmonary tuberculosis were included. Before treatment and at the end of three months, the abnormal pulmonary function results were 204 cases (80.95%) and 193 cases (76.59%), respectively, and the difference was not statistically significant ( P>0.05). Among them, abnormal pulmonary ventilation function is the most common, especially with obstructive, followed by abnormal diffusing capacity. At the end of three months, the proportions of patients with normal pulmonary ventilation function and normal lung volume were higher than that before treatment ( P<0.05), but there was no significant difference in the proportion of normal diffusing capacity before and after treatment ( P>0.05). The values of FVC, FEV 1, TLC and D LCO at the end of three months were higher than those before treatment, and the difference was statistically significant ( t=-6.414, -6.754, -3.863, -3.311, all P<0.01). Conclusions:Most patients with pulmonary tuberculosis have abnormal pulmonary function. At the end of the three months treatment, the normal rates of the pulmonary ventilation function and lung volume as well as the values of FVC, FEV 1, TLC and D LCO in patients with pulmonary tuberculosis were significantly improved compared with those before treatment.

BACKGROUNDThe Xpert MTB/RIF showed high sensitivity and specificity in previous studies carried out in different epidemiological and geographical settings and patient populations in high-burden tuberculosis (TB) countries. However, there were little data obtained by validation or demonstration study of the assay in China. In this study, the performance of Xpert MTB/RIF was investigated in two county-level laboratories in Hunan Province, China.

METHODSConsecutive patients with suspected pulmonary tuberculosis (PTB) and suspicion for multidrug-resistant tuberculosis (MDR-TB) were enrolled. For each patient suspected to have PTB, three sputum specimens (one spot sputum, one night sputum, and one morning sputum) were collected and each sputum was tested with smear microscopy, Löwenstein-Jensen (LJ) culture, and Xpert MTB/RIF test. For comparison across subgroups and testing methods, 95% confidence intervals were calculated. All analyses were done with SPSS 16.0, and P < 0.05 was regarded as significant.

RESULTSFor case detection, the sensitivity of Xpert MTB/RIF was 100% for smear- and culture-positive TB and 88.6% for smear-negative and culture-positive TB; the overall sensitivity was 94.5% for all culture-positive patients. The specificity was 99.8%. The sensitivity of Xpert MTB/RIF assay was 22.0% in clinical TB patients and the specificity reached 100.0% in the group of patients who are infected with nontuberculous mycobacteria. For the detection of rifampin resistance, the sensitivity of MTB/RIF RIF-resistance detection was 92.9%, and the specificity was 98.7%. Of the 26 Xpert MTB/RIF-positive and RIF-resistant patients confirmed by LJ proportion tests, 20 (76.9%) patients were infected by MDR-TB.

CONCLUSIONSThe Xpert MTB/RIF assay is a highly sensitive and specific method for diagnosis of TB and RIF resistance, which will enable it to have the potential to be used in county-level laboratories and lead to the reduction of the infectious pool and improvements in TB control in China. Further evaluations in county-level laboratories for implementing the assay are still required.
