Objective To analyze the clinical characteristics and therapy of levofloxacin-induced prolonged Q-T interval in patients with multi-drug resistant tuberculosis ( MDR-TB) . Methods Clinical materials of 6 patients with MDR-TB who developed prolonged Q-T/QTc interval caused by levofloxacin therapy were analyzed. Those cases were collected from the Tuberculosis Prevention and Control of Wuhan City form April 2010 to August 2014. Results The proportion of patients with levofloxacin-induced prolonged Q-T interval was approximately 3.0%.The condition occurred 2-8 months after the administration. The initial value of QTc interval ranged from 397 ms to 439 ms, while the average was (410.17±14.62) ms.The value of QTc interval was extended to 470-486 ms after treatment of levofloxacin, while the average was (476.33±6.16) ms.The increase of QTc interval was 47-85 ms, while the average was ( 66 ± 11. 48 ) ms. None of them developed Tdp. Conclusion The application of high dosage and long treatment course of levofloxacin in patients with MDR-TB could result in the extension of the Q-T/QTc interval, which should arouse our serious attention. In order to detect the abnormal Q-T/QTc interval in early stage, electrolyte level examination as well as ECG examination should be considered as routine tests before initiation of treatment and during the follow-up treatment.

Objective To compare the effect of general anesthesia and combined spinal-epidural anesthesia on short-term cognitive function in the elderly patients in the department of orthopedics.Methods Totally 60 elderly patients in the department of orthopedics were randomly divided into the general anesthesia group and the combined spinal-epidural group.The effect of anesthesia and the short-term cognitive function after operation were compared between the two groups.Results Before anesthesia induction and 6,12,72 h after anesthesia,there was no significant difference in the score of cognitive function between the two groups (P ＞ 0.05).24 h after anesthesia,the score of cognitive function in the general anesthesia group was significantly lower than that in the combined spinal-epidural anesthesia group (P ＜ 0.05).There was no significant difference in the postoperative heart rate and neuropsychosis between the two groups (P ＞ 0.05).Conclusion General anesthesia is easy to cause cognitive impairment,so it is recommended to give priority to combined spinal-epidural anesthesia.

Objective To explore the influence of acupuncture point massage combined with limb function exercise on ankle brachial index (ABI) and pulse wave velocity (PWV) in patients with coronary heart disease (CHD). Methods According to scores by grace score scale, 180 CHD patients were divided into three groups: low risk group (n=58), moderate risk group (n=68) and high risk group (n=54). Within the three groups, the patients were divided into the experiment group and the control group by using the random digital table. The control group was treated with routine nursing intervention , while the experiment groups accepted acupuncture point massage and limb function exercise training on the basis of control groups. We collected the values of ABI and PWV at four points-in-time: before intervention, 7 days after intervention, 30 days after intervention and 90 days after intervention. Results Repeated measurement data analysis of the experiment group and control group suggested that:in the moderate and high risk groups, there was statistically significant difference (P<0.05) in the data at the four time points. There was no statistically significant difference (P > 0.05) in time and group interaction effect. The difference between the experiment group and control group was statistically significant (P<0.05). Repeated measurement data analysis showed that there was no statistically significant difference (P>0.05) in ABI&PWV interaction effect at the four time points between the experiment group and control group. In the low-risk group,the differences in time points compared with the main effect were insignificant (all P>0.05). In comparison of main effect at all the four time points, there was significant different in the moderate and high risk group (P<0.05), And it suggested that time and group interaction, namely effect of time factor (1 d, 7 d, 30 d, 90 d), was not decided by the division of groups. In comparison of main effect, the difference was statistically significant (all P < 0.01) in the moderate and high-risk group, which indicated the main effect (intervention) playing main role. However, there was no statistically significant difference (P>0.05) of ABI&PWV before and 90-days after intervention. Conclusion Acupuncture point massage combined with limb function exercise can effectively improve the peripheral artery blood supply in CHD patients, lower ABI and promote PWV.

OBJECTIVETo study the biomass structure of Epimedium acuminatum Franch in the different ecological environments for the development and protection.

METHODThrough the scientific investigation in four typical habitats, the sampling spots were set up, the functional modules' biomass structure and relationship of E. acuminatum were researched.

RESULTThe average of rhizome, as the largest biomass, and the average total biomass had the same pattern: the open areas of forest edge > shrub lumber > shrub-weed > stream drains. The ratio of the functional modules' biomass had different rates under different habitat conditions. By analyzing and combining investigation, the aerial part of E. acuminatum in the shrub-weed were comparative advantage, and the roots of nutrient accumulation of E. acuminatum in the open areas of forest edge were the highest efficient. Under different ecological condition, the distribution of water metabolism was different strategies.

CONCLUSIONIn the open areas of forest edge, E. acuminatum growing well, followed by shrub-weed. These two habitats are the ideal ecological environments while the rhizome or the whole plant used as medicine, but also the protection of E. acuminatum.

Objective: To investigate the survival time of multidrug-resistant tuberculosis (MDR-TB) patients and the influential factors in Wuhan. Methods: The relevant information were collected from TB management information system, cause of death reporting system and medical records by trained doctors. The univariate and multivariate Cox proportional hazards model were applied to analyze the factors affecting survival time of patients. Results: A total of 552 patients with MDR-TB were included in the analysis. After the diagnosis of MDR-TB, the cumulative survival rates from the first year to the third year were 0.94, 0.88, and 0.80, respectively. The mortality density of MDR-TB patients was 6.52/100 person-years, and the median survival time was (89.52±1.85) months. Kaplan-Meier analysis showed that the cumulative survival rate of the standardized treatment group was significantly higher than that of the non-standardized treatment group (Log rank=101.070, P<0.001). Compared with the patients aged <30 years, the HR of the patients aged 30-years and ≥60 years were 2.987 (95%CI: 1.268-7.036), 4.957 (95%CI: 1.942-12.653). Compared with the patients with the education level of high school and above, the HR of the patients with education level of junior high school/primary school and below were 1.908 (95%CI: 1.152-3.160), 1.681(95%CI: 1.033-2.735). Compared with the patients without diabetes, the HR of the patients with diabetes was 1.961(95%CI: 1.347-2.854). Compared with the patients without other serious diseases, the HR of the patients with other serious diseases was 2.597 (95%CI: 1.820-3.706). Compared with the patients who had been treated less than one time, the HR of the patients having previous treatment with more than 2 times was 1.611 (95%CI: 1.077-2.409). Compared with patients receiving standard MDR regimen treatment, the HR of the patients receiving no standard MDR regimen treatment was 3.155 (95%CI: 2.132-4.670). Conclusions The cumulative survival rate of MDR-TB patients without standard treatment was significantly lower than that of patients with standard treatment. Older age, low educational level, diabetes mellitus, other serious diseases, more than two times treatment in the past, and receiving no multi-drug resistance regimen treatment were the risk factors affecting the survival of MDR-TB patients.

OBJECTIVETo study the relationship between the genetic diversity and chemical variation of Cinnamomum migao.

METHODISSR marker technique was used to research the genetic structure of 9 population, GC-MS was used to analyze the main ingredients of the volatile oil in C. migao.

RESULTThe analysis on the main ingredients of the volatile oil showed that there were significant or extremely significant differences in 9 populations. The minimum variation index of population was Yunnan Funing and the maximum variation index of population was Guangxi Yueye. ISSR marker analysis showed that the average of polymorphic loci percentage (P) was 42.41%, expected heterozygosity (H) was 0.181 0, Shannon's information index (I) was 0.293 8, the Nei's genetic diversity (H(s)) in the group was 0.188 9, genetic differentiation index (G(st)) was 2.269 1. The relationship between the genetic diversity and chemical variation showed that there was no significant correlation between the main ingredients of the volatile oil and 4 indexes of genetic structure of C. migao.

CONCLUSIONThe genetic diversity of C. migao was relatively high at the population levels, while it is low within the population levels, the relationship between chemical variation and genetic diversity was not obvious, that may indicate that other factors causes the chemical variation of C. migao.

Objective: To analyze the epidemiological characteristics of pulmonary tuberculosis among students in Wuhan from 2011 to 2020, and to provide a basis for the scientific development of interventions and strategies. Methods: Epidemiological distribution, time of onset and treatment, as well as treatment outcomes of student tuberculosis in Wuhan from 2011 to 2020 registered in the national tuberculosis information management system were described. Results: During 2011-2020, 4 337 student tuberculosis patients in Wuhan were registered. The average annual incidence rate was 22.44/10 million, and the annual decreasing rate of 7.86% The incidence of male and female patients was 1.76:1, and the incidence rate of male was higher than that of female( χ 2=184.18, P <0.01). Most of patients aged 19-22 years old, accounting for 47.89%; Tuberculosis reports were highest during March to May, and September to November, and lowest during January to February, and July to August. Student patients were mainly concentrated in Hongshan District, Jiangxia District and Wuchang District, where schools were more distributed in Hongshan District, Dongxihu District, Wuchang District and Xinzhou District. The median duration from tuberculosis onset to treatment was 9(3, 21) days, which varied significantly by region, age, nationality, and patient residence ( Z =-9.25, 47.14, 9.88,43.96, P <0.01). The treatment and outcome of student tuberculosis patients were varied significantly by year and nationality( P <0.05). Conclusion The incidence of student tuberculosis in Wuhan City showed a slow downward trend. Most of student tuberculosis are college and high school students. Time and place of case detection are relatively fixed. The time of treatment and the outcome of treatment vary significantly. Tuberculosis prevention and control strategies should be formulated according to the local conditions according to the tuberculosis distribution characteristics, as well as enhancing surveillance, health promotion, active discovery and supervision management of tuberculosis in school settings.

Objective: To study the efficacy, safety and long-term outcomes of integrated strategy of bortezomib-based induction regimens followed by autologous hematopoietic stem cell (ASCT) and maintenance therapy in Chinese multiple myeloma (MM) patients. Methods: 200 MM patients receiving integrated strategy of bortezomib--based induction regimens followed by ASCT and maintenance therapy were retrospectively and prospectively analyzed from December 1. 2006 to April 30. 2018. Results: The complete remission rates (CR) and better than very good partial remission rates (VGPR) after induction therapy, transplantation and maintenance therapy were respectively 31% and 75.5%, 51.8% and 87.7%,73.6% and 93.4%. There was no difference between 4 cycles and more than 5 cycles induction chemotherapy. The negative rate of MRD detection by flow cytometry was 17.6% and 38.2% respectively after induction and 3 months after transplantation. The negative rate of MRD gradually increased during the maintenance therapy. The success rate of high dose CTX combined with G-CSF mobilization was 95.5% and transplantation related mortality (TRM) was zero. The median time to progress (TTP) was 75.3 months and the median overall survival (OS) was 99.5 months. TTP of patients obtaining CR and negative MRD after induction were longer that those of no CR and positive MRD. TTP and OS of patients receiving triple-drug induction and ASCT in early stage were longer than those of double-drug induction and ASCT in late stage. LDH≥240 U/L, high risk cytogenetics, ISS II+III stage and HBsAg positive were prognostic factors at diagnosis. However, only MRD and high risk cytogenetics were independent prognostic factors after transplantation and maintenance therapy. The clinical characteristics of patients of TTP ≥6 years were listed below: light-chain type M protein, ISS I stage, normal level of hemoglobin and platelet, normal LDH, HBsAg negative, chromosome 17p-negative, good response and sustained good response. Conclusions Integrated strategy of bortezomib-based induction regimens followed by ASCT and maintenance therapy can significantly improve the short-term and long-term efficacy. The prognostic factors of TTP in different disease stages were different. Response to treatment, especially MRD, played a more important role in prognostic factors.
