Objective To analyze the clinical efficacy of pre-extensive drug resistant tuberculosis (pre-XDR-TB), and to explore the feasibility of using the standard multidrug resistant tuberculosis (MDR-TB) therapeutic regimen to treat the patients with pre-MDR-TB. Methods A retrospective analysis was made for 126 cases of the MDR-TB patients who were received the treatment in Guangzhou chest hospital from 2009 to 2013. It was divided into MDR-TB group, pre-XDR-TB group and XDR-TB group according to the drug sensitive test (DST) of quinolone(levofloxacin, moxifloxacin) and aminoglycoside (amikacin). All patients were treated for 6-months with the standard therapeutic regimen including Am(Cm), Lfx(Mfx), Pto, PAS and PZA. Results (1) There were 126 cases of the MDR-TB patients in the study, 31 cases (24.6%) complicate with aminoglycosides-resistance, 69 cases (54.7%) complicate with quinolone-resistance. (2) The negative rate of MDR-TB group, pre-XDR-TB group and XDR-TB group was 82.0%, 55.8% and 29.2% respectively (χ2 = 20.110, P < 0.001). (3)The negative rate of pre-XDR-TB group significantly lower than MDR-TB group (χ2 = 8.146, P = 0.004). The negative rate of pre-XDR-TB group higher than XDR-TB group (χ2= 4.661, P = 0.031). Conclusions The situation of quinolone and aminoglycoside resistance was high in the patients with MDR-TB. We should carry out the detection of quinolone and aminoglycoside resistance in clinical treatment. The clinical efficacy for the patients with pre-XDR-TB was significantly poorer than the patients with MDR-TB using the standard MDR-TB therapeutic regiment treated.

Objective To investigate the effects of 14-3-3 phosphorylation (p-14-3-3) induced by C-Jun N-termi-nal kinase (JNK) on ischemic brain injury in rats. Methods Twenty rats were divided into 4 groups:sham operation group, ischemia-reperfusion group, SP600125 group and solvent control group. The rat model of cerebral ischemia was established. The p-14-3-3, the binding of 14-3-3 and Bax and the protein expression of Bax in cytoplasm and mitochondria in hippo-campal CA1 region were detected by immunoprecipitation (IP) and immunoblotting 12-hour after ischemia-reperfusion in four groups. Results Compared with the sham operation group, protein expression levels of p-14-3-3 in cytoplasm and Bax in mitochondria were significantly increased, the binding of 14-3-3 and Bax was significantly decreased in ischemia-re-perfusion group, solvent control group and SP600125 group. The protein expressions of p-14-3-3 and Bax were significantly lower in SP600125 group than those of ischemia-reperfusion group and solvent control group. The binding of 14-3-3 and Bax was significantly higher in SP600125 group than that of ischemia-reperfusion group and solvent control group (P <0.05). Conclusion 14-3-3 phosphorylation induced by JNK plays important effects on ischemic brain injury in rats.

Objective To investigate the effects of different liver protective drugs on preventing liver injury induced by anti-tuberculosis drugs. Methods Retrospective analysis was made on 355 patients with primary pulmonary tuberculosis during intensified time. The patients received silibinon and bicyclol to prevent liver injury. 82 patients with TB were treated as control group during the same time. Results The number of patients with liver injury in silibinon group and bicyclol group were 16 cases (14.7%) and 55 cases (22.4%) respectively. The number of control group with liver injury was 9 cases (11.0%) (χ2 = 3.627,P > 0.05). The liver injuries within 4 weeks were mainly counted in. There is no difference between intervention and control groups(χ2 = 0.414,P > 0.05). There is no difference between three groups in liver injury degree (U = 0.288,P> 0.05). Conclusion Without high risk factors, anti-inflammatory and enzyme reduction drugs have no significant protective effects on liver injury caused by anti-tuberculosis drugs.

Objective To study the correlation of PAZ with anti-tuberculosis treatment regimen and drug-induced liver injury in tuberculosis patients with HBV-DNA positive in order to provide an optimized treatment regimen. Methods from Jan 2013 to Dec 2014, 199 pulmonary tuberculosis with HBV-DNA positive patients and 103 pulmonary tuberculosis patients without HBV in our hospital were collected. They were assigned as follows:122 cases were anti tuberculosis treatment with antiviral therapy,64 cases were A(HRZE),58 cases were B (HRE). 77 cases were anti tuberculosis treatment but not antiviral therapy , 41 cases were C (HRZE), 36 cases were D(HRE) and 103 patients without HBV were E (HRZE, the contrast group). We had observed the liver injury for 2 months after the treatment. Results 1.Incidence of liver injury was 34.38% in group A , higher than the cases in group B(20.69%,P > 0.05). 2.Incidence of liver injury in group C was apparently higher than in group D (73.17% vs. 30.56%,P < 0.05). 3.Incidence of liver injury in group B was lower than group D (20.69% vs. 30.56%,P > 0.05)4.Incidence of liver injury in group A was lower than group C (34.38% vs. 73.17%,P < 0.05).5. Incidence of liver injury in group A was higher than group E (34.38% vs. 17.48%,P< 0.05)and there was no difference between group B and group E (20.69% vs. 17.48%,P> 0.05). Conclusion Although anti tuberculosis treatment combined with antiviral therapy can be partially reduce the incidence of liver injury and relieve the severity of liver injury in tuberculosis patients infected with HBV , but PZA toxicity to hepatocytes is a major risk factor for liver injury , and we need to change the treatment plan to reduce the occurrence of liver injury.

OBJECTIVETo compare the clinical characteristics of rifampin-dependent (R-dependent Mycobacterium tuberculosis) and rifampin-resistant (R-resistant Mycobacterium tuberculosis) patients with pulmonary tuberculosis.
METHODSThe clinical data including the demographic data, age groups, course of disease, history of chemotherapy with anti-TB drugs, and results of drug susceptibility test were collected from 61 cases of R-dependent pulmonary tuberculosis and 148 cases of R-resistant pulmonary tuberculosis treated between October, 2008 and January, 2012.
RESULTSMost of the R-dependent and R-resistant patients were between 30 and 44 years of age. The R-dependent patients included 12 receiving the first treatment patients and 49 with previous treatments, and the R-resistant patients included 11 without and 137 with previous treatments. The multi-drug resistant rate was 80.3% in R-dependent group, as compared to 92.6% in R-resistant group.
CONCLUSIONMost of the patients infected with R-dependent Mycobacterium tuberculosis are young or middle-aged, often having serious disease conditions. Detecting rifampin dependence is important for patients with initial treatment failure. Multi-drug resistance therapy guideline should be applied to patients infected with R-dependent Mycobacterium tuberculosis to improve the cure rate.

Objective:To investigate the application value and treatment opportunity of single balloon enteroscopy in children with Peutz-Jeghers syndrome(PJS).Methods:A retrospective analysis was conducted on 33 children diagnosed with PJS in Hunan Children′s Hospital from January 2011 to September 2021.The patient′s age, gender, family history, clinical symptoms, enteroscopy examination and treatment, number of polyps, intraoperative and pos-toperative complications, surgical treatment, recurrence of surgery, and follow-up data were analyzed, and the chi- square test was used for statistical analysis. Results:A total of 33 PJS children aged (9.00±3.13) years, including 21 males and 12 females, were included.All of them received at least once single balloon enteroscopy test.The main manifestations of the children were black spots (33 cases) and multiple polyps in the digestive tract (31 cases). In all the 33 cases, black spots were distributed on lips.Some black spots were also found at the end of fingers (3 cases), at the end of foot toes(2 cases), and at the end of finger toes (6 cases). During the operation, 391 polyps were removed, most of which were jejunum polyps (37.08%, 145/391 polyps). Eleven children with PJS has intussusception, of which intestinal intussusception accounted for 90.91% (10/11 cases). Ten cases (30.30%, 10/33 cases) received surgical treatment, and 72.73% (8/11 cases) underwent surgery for acute refractory intussusception.One case had intestinal perforation and 2 cases were bleeding during the operation, and the 3 cases recovered completely after hemostatic clip sealing and surgical treatment.The incidence of hollow ileum polyps and giant polyps in children aged >8 years was higher than that in children aged ≤8 years[92.55% (149/161 polyps) vs.7.45%(12/161 polyps), 96.20%(76/79 polyps) vs.3.80% (3/79 polyps)]. The differences were statistically significant ( χ2=9.854, 8.711, all P<0.05). There was no significant difference in the incidence of intussusception among different age groups ( P>0.05). Among the 33 children with PJS, 57.58% (19/33 cases) had recurrence 1-3 years after operation, and no cases of cancer have been followed up so far. Conclusions:Intestinal polyps are common in children with PJS, and the application of single-balloon enteroscopy in children with PJS is reliable and safe.Children over 8 years old are more vulnerable to empty ileum polyps and giant polyps.Therefore, it is advised that children aged above 8 years with PJS should undergo at least once enteroscopy.
