Objective To evaluate the clinical efficacy and safety of combination treatment with clofazimine ( Cfz ) and other antituberculosis drugs for patients with multidrug-resistant tuberculosis(MDR-TB).Methods 32 cases of MDR-TB patients were treated with combination regimens that included clofaziminefrom October 2011 to September 2016 in our hospitol,according to the history of drug use and drug susceptibility test results using individualized chemotherapy,the starting dose of clofazimine was 0.1 g/day,oral,some patients with adverse reactions and tolerance adjusted to 0.05 g/day,treatment for the last 12 months for three consecutive sputum mycobacterium tuberculosis culture and sputum smear acid-fast bacilli were cured,observe the clinical efficacy and safety.Results After treatment with the combined regimen,56.2%(18/32) of patients were cured,43.8%(14/32) of patients failed treatment, there was no statistically significant difference in the number of drug-resistant patients before and after CFZ treatment,there was no statistically significant difference between the time of failure and the time of CFZ treatment,after taking CFZ combined with anti-tuberculosis program,the number of drug users was statistically significant of patients cured and failed (P<0.05).The average time of sputum culture inversion was 16w.90.6% (29/32) of patients with adverse reactions,mainly including skin color change,ichthyosis and gastrointestinal tract and other adverse reactions, through dose adjustment and symptomatic treatment to continue treatment.The average duration of treatment with clofazimine was about 13 months.ConclusionClofazimine was welltolerated,combination treatment with Clofazimine and others for patients with MDR-TBhave better efficacy .

Aim To confirm the inhibitory effect of chronic intermittent hypobaric hypoxia ( CIHH) on my-ocardial apoptosis induced by metabolism syndrome ( MS) , and to investigate its mechanism. Methods A rat model of MS induced by fructose was used. The blood pressure and the plasma content of glucose, tri-glyceride, cholesterol, and insulin after 12 h fasting were detected. HE stain were used to detect the cardi-ac structure. The TUNEL staining and activity of caspase-3 were used to detect the apoptosis of myocar-dium. The protein expression of Bcl-2 and Bax was detected by Western blot . Results Compared with the control rats, the blood pressure and the plasma content of glucose, triglyceride, cholesterol, and insu-lin were all increased in rats with MS. In rats with MS, the impairment of cardiac structure and the increase of apoptosis were also observed. The protein expression of Bcl-2 was significantly down-regulated, and that of Bax was significantly up-regulated in MS rats. The ratio of Bcl-2/Bax was also significantly decreased. Interest-ingly, CIHH could ameliorate all of the above issues. There was no significant difference between control group and CIHH group. Conclusion CIHH may im-prove the increased apoptosis in rats with MS via inhib-iting the mitochondrial pathway of apoptosis. This stud-y might provide new targets for therapy and the preven-tion of MS patients.

Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

BACKGROUND:Large numbers of experimental data have confirmed that bone marrow mesenchymal stem cel s have a positive therapeutic effect on cerebral ischemia-reperfusion injury, but there are few reports about intravenous administration of bone marrow mesenchymal stem cel conditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the effects of the conditioned medium of rat bone marrow mesenchymal stem cel s on the recovery of neurological function in rats after cerebral ischemia-reperfusion injury.
METHODS:The bone marrow mesenchymal stem cel s were isolated from rat bone marrow. When cel s at passage 2 or 3 reached 90%confluence, the original culture medium was removed. Then the cel s were cultured in serum-free DMEM for 18 hours. After that, the culture solution was col ected as the conditioned medium of rat bone marrow mesenchymal stem cel s. Adult rats were subjected to 2 hours of right middle cerebral artery occlusion. Ischemia-reperfusion injury rats were randomly assigned to three groups:control group, simple culture medium group and conditioned medium group, and respectively given injection of normal saline, DMEM, conditioned medium (10 mL/kg) via the tail vein at 2, 24, 48 hours after operation.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperative 2 hours (P>0.05). Compared with the control and simple culture medium group, neurological impairment was significantly improved in the conditioned medium group at postoperative 1, 3, 5 days (P<0.05), but there was no significant difference between the control and simple culture medium groups. At postoperative 5 days, brain edema was significantly eased in the conditioned medium group in comparison to the control and simple culture medium groups (P<0.05), and there was also no difference between the latter two groups (P>0.05). These results suggest that rat bone marrow mesenchymal stem cel s-conditioned medium via intravenous administration can significantly ease brain edema and improve the neurologic function after cerebral ischemia-reperfusion injury.

OBJECTIVETo evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS).

METHODSSixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0. 33 g/capsule, 3 times per day) and Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day) , while those in the control group only took Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day). The therapeutic course for all was 6 weeks. IBS symptom score questionnaire, IBS-Quality of Life (IBS-QOL) , Self-Rating Depression Scale (SDS) , and Self-Rating Anxiety Scale (SAS) were assessed before and after treatment. Adverse reactions were also observed.

RESULTSThe improvement of abdominal pain, stool frequency, and stool properties, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of dysphoria, body image, concerns for health, and dietary restriction of IBS-QOL, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of SDS and SAS, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). No severe adverse reaction occurred in either group.

CONCLUSIONCombination therapy of wuling Capsule and Pinaverium Bromide could improve abdominal pain and defecation, attenuate depression and anxiety of IBS patients with higher safety.

Objective:To explore clinical application value of immediate breast reconstruction with silicone prosthesis after nipple areolar sparing mastectomy for breast cancer.Methods:The clinical data of 30 breast cancer patients underwent immediate breast reconstruction with the silicone prosthesis after nipple areolar sparing mastectomy from January 2016 to January 2018 were collected. In the observation group, 15 patients underwent immediate breast reconstruction with the silicone prosthesis after nipple areolar sparing mastectomy. In the control group, 15 patients underwent conventional modified radical mastectomy only. The differences of operation indicator and postoperative complications between the two groups were compared, and the postoperative cosmetic effects were evaluated.Results:The patients successfully completed prosthetic breast reconstruction in the observation group. The surgical time and indwelling time of the drainage tube in the observation group were both increased compared with the control group, and the difference was statistically significant ( t=118.8 and t=23.9, P<0.05). There were no statistically significant differences between the two groups in the complications of postoperative flap necrosis, subcutaneous hematoma, intraoperative infection and incision dehiscence ( P>0.05). The total complications rate of the observation group was 40%, compared with the control group (20%), there were not statistically significant differences ( P>0.05). The postoperative aesthetic effect evaluation showed that the reconstructed breast was full in shape and basically symmetrical to the contralateral side, with an excellent and good rate of 83.3%. The patients were satisfied with the appearance of the breast. All patients were followed up for 12 to 36 months with the average time of 24 months, and local recurrence and distant metastasis were not observed. Conclusions:In the modified radical mastectomy for breast cancer with preserved nipple and areola, the immediate application of silicone prosthesis for breast reconstruction has the advantages of less trauma, faster postoperative recovery and better cosmetic effect, which is worthy of clinical application.

The aim of this study is to investigate the effects of chronic intermittent hypobaric hypoxia (IHH) and chronic continuous hypobaric hypoxia (CHH) on hemodynamics under basic normoxia and acute hypoxia conditions and to find the difference of two types of chronic hypoxia. Forty adult male Sprague-Dawley (SD) rats were randomly divided into 5 groups: Control group (CON), 28 days IHH group (IHH28), 42 days IHH group (IHH42), 28 days CHH group (CHH28) and 42 days CHH group (CHH42). The rats in IHH groups were treated with intermittent hypoxia (11.1% O2) mimicking 5 000 m altitude in a hypobaric chamber for 28 or 42 d, 6 h a day, respectively. The rats in CHH groups lived in the hypobaric chamber with the same degree of hypoxia like IHH rats except half an hour in normoxia each day for feeding and cleaning. The body weight of rats was measured once a week. The parameters in hemodynamics, such as mean artery blood pressure (MAP), heart rate (HR), left ventricular systolic pressure (LVSP), maximum change rate of left ventricular pressure (+/-LVdP/dt(max)) were recorded under basic normoxia and acute hypoxia conditions through catheterization technique. The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardium of rats were measured by biochemical method. The weights of whole heart, left and right ventricles were measured separately. The results showed: (1) The basic HR and MAP in CHH42 rats were lower than those in CON, IHH and CHH28 rats (P<0.05). (2) IHH showed a cardioprotection against acute hypoxia and reoxygenation injury, manifested as the result that the changes of HR, MAP, LVSP, and +/- LVdP/dt(max) were smaller than those in CON rats during acute hypoxia and reoxygenation. CHH showed a rather strong cardioprotection during acute hypoxia, manifested as the result that the decreases of HR, MAP, LVSP, and +/- LVdP/dt(max)were much smaller, but it did damage during reoxygenation, manifested as the result that the recovery of hemodynamics was the worst among three groups (P<0.05). (3) The antioxygenation of heart was increased in both IHH and CHH rats compared with that in CON rats manifested by the increased SOD activity and decreased MDA content (P<0.05, P<0.01). (4) IHH had no effect on heart weight, but CHH rats showed an obvious right ventricular hypertrophy compared with CON and IHH animals (P<0.01). The result indicates that IHH can induce a more effective cardioprotection with no much side effect, which might have a potential value for practical use.

Objective:To analyze the relationship between serum antibody titers, clinical characteristics, and prognosis in patients with encephalitis induced by anti leucine-rich glioma inactivated 1 (LGI1) antibody.Methods:Clinical data of 20 patients diagnosed with encephalitis in the Department of Neurology, First Hospital of Shanxi Medical University from February 2015 to February 2021 were collected and retrospectively analyzed. Patients were divided into 2 groups based on their serum anti LGI1 antibody titers, namely the high titer group (1∶100, 1∶320) and the low titer group (1∶10, 1∶32). The clinical characteristics, laboratory test results, and prognosis of the 2 groups of patients were compared. Relusts The age of the 20 patients with anti LGI1 antibody encephalitis ranged from 27 to 69 (53.5±11.2) years, with a male to female ratio of 1∶1. There were 9 patients in the low titer group and 11 patients in the high titer group. There was no statistically significant difference in the types and quantities of clinical symptoms between the 2 groups. Patients in the high titer group were more prone to abnormal lesions on cranial magnetic resonance imaging (10/11 vs 3/9, P=0.014). There was no statistically significant difference between the 2 groups in the presence or absence of cerebrospinal fluid anti LGI1 antibodies (9/11 vs 4/9, P=0.160). During the follow-up, it was found that 1/20 patient died of pulmonary embolism, 7/20 of patients were able to recover to their predisease state, and 9/20 of patients had residual memory impairment. In the high titer group, 3/11 of patients experienced recurrence, while there was no recurrence in the low titer group. There was no statistically significant difference in the neurological prognosis between the 2 groups at 3 months of discharge and follow-up (the number of patients whose modified Rankin Scale score≤2: 10/10 vs 8/9, P=0.474). Conclusions:Patients with high serum anti LGI1 antibody titers are more likely to develop intracerebral lesions. Higher antibody titers may be associated with a higher risk of disease recurrence. There was no significant correlation between serum antibody titers and neurological outcomes.

Objective:To clarify the influence and influence paths of stigma on the time of the healthcare-seeking decision in caregivers of elderly patients with dementia, and to provide a theoretical basis for the construction of corresponding humanistic care strategies.Methods:A total of 176 caregivers of elderly patients with dementia who visited the Affiliated Hospital of Xuzhou Medical University and Xuzhou Oriental People ′s Hospital from February 2021 to February 2022 were selected as the study subjects. The General Information Questionnaire, self-designed Scale of Stigma for Caregivers of Senile dementia patients, Multidimensional Scale of Perceived Social Support, self-designed Elderly Dementia Caregivers′ Perceived Barriers Scale for Healthcare-seeking Decision, and self-designed Scale of the Intention to Seek Healthcare for caregivers of senile dementia patients were used in the survey. AMOS 20.0 was used to establish a structural equation model for path analysis. Results:The higher the stigma of caregivers, the longer the time of the healthcare-seeking decision ( β=0.05, P<0.05). Social support, perceived barriers to the healthcare-seeking decision, and the intention to seek healthcare were the mediating variables of caregivers ′ stigma affecting the time of the healthcare-seeking decision, with a total effect of -0.04, 0.14, and 0.36, respectively, and all P<0.05. Conclusions:The stigma in caregivers of senile dementia patients is an important factor affecting the time of the healthcare-seeking decision. By improving mediating factors including social support, perceived barriers to the healthcare-seeking decision, and the intention to seek healthcare, the implementations of targeted humanistic care strategies are expected to help shorten the time of the healthcare-seeking decision.
