Objective To investigate the influence of multi-drug resistant mycobacterium strain tuberculosis (MDR-TB) on the clinical outcomes and its countermeasures in the treatment of bone and joint tuberculosis. Methods From December 1993 to June 1999, 250 revised cases were admitted in our hospital, which were 143 males and 107 females aging from 2 to 72 years with an average of 25.44 years. The most of lesions were located at spine, then the hip, knee and small joints. The specimens were harvested via need biopsy or operation from the lesion. Specimens were examined by Bactec TB 460 to identify tuberculosis mycobacterium and non tuberculosis mycobacterium strain, and drugs-sensibility test to INH(0.2 ?g/ml), SM (6.0 ?g/ml), RFP (2.0 ?g/ml) and EMB (7.5 ?g/ml) respectively. Results Of 250 patients, Mycobacterium were positive in 48 by Bactec measurement, which were tuberculosis mycobacterium strain in 46 with 18.4% positive rate, and non tuberculosis mycobacterium strain in 2(1 mycobacterium avium intracellulare complex, the other unkown). Of the 46 positive specimens, 27 were sensitive to all of 4 drugs(58.7%), however, 3 were resistant to 1 drug(6.5%), 1 was resistant to 2 drugs(2.1%), 4 were resistant to 3 drugs (8.7%), and 11 were resistant to 4 drugs(24%). In 11 patients resistant to 4 drugs and 2 patients with non tuberculosis mycobacterium strain, 8 were complicated with sinuses after the first operation, in which 7 healed after 2 to 3 re-operations and 1 died of secondary infection. 1 M. avium intracellulare complex and 1 unidentified mycobacterium were multi-drug resistant strains( INH,RFP, SM, EMB) and found with poor clinical results.Conclusion Those cases with MDR-TB in lesions can influence the curative effect of bone and joint tuberculosis significantly. Based on the drug-sensibility, the chemotherapy regimen should be modified and individualized, and requires several operations to cure.

Abstract Social network of adolescents is one of the important factors affecting the initiation and development of their unhealthy eating behaviors, and different types of social networks shows varied influences on adolescents eating behaviors through divergent mechanisms. In the context of the new media era, social networks of adolescents establish via social media appear more complex and extensive. Based on relevant previous literature, the paper explores the impact and possible mechanisms of social network on eating behavior of adolescents, as well as its development and application in the new media era to provide references for better intervention strategies and healthier eating behaviors among adolescents from the perspective of social network.

Objective This study was to develop a"Spleen Deficiency Certificate Scale for County Residents"and test its reliability.It was then developed as an objective tool for Chinese medicine evidence and symptoms for the prevention and control of chronic diseases among county residents.Methods The scale was compiled based on the team's previous foundation.The reliability of the scale was evaluated using internal consistency reliability and split-half reliability,while its validity was evaluated using structural validity,content validity,calibration validity,and discriminant validity.Results The study included 213 adults from Lanxi,of whom 155 were tested for intestinal flora.Seven scale entries were identified:Fatigue,fear of cold,bland mouth,loss of appetite,diarrhea,weak bowel movements,and tooth-marked tongue.In the reliability test,Cronbach's alpha coefficient was 0.828 and McDonald's ω coefficient was 0.825.The"stomach pain"and"bloating"entries did not meet the inclusion requirements and were recommended to be deleted.The Spearman-Brown coefficient was 0.839.The exploratory factor analysis of the two common factors explained 61.6%of the cumulative variance.The calibration validity indicated that the ratio of salivary amylase activity before and after acid stimulation was 0.826±0.253 in the group with spleen deficiency.Significant differences(P<0.05)in the genera Dialister,Shigella,Leuconostoc,Photobacterium,Trabulsiella,and Parvimonas between the spleen deficiency group and the non-spleen deficiency group.Conclusion The Spleen Deficiency Scale for County Residents demonstrates good reliability and validity.

OBJECTIVETo observe the clinical efficacy of acupuncture and moxibustion periodic therapy on folli-cular maldevelopment differentiated as spleen and kidneydeficiency.

METHODSSixty patients of follicular maldevelopment differentiated as spleen and kidneydeficiency were randomized as an observation group and a control group, 30 cases in each one. The conventional acupuncture-moxibustion therapy was used in the control group and the acupuncture-moxibustion periodic therapy was applied to the observation group. In the control group, the acupoints were selected in terms of spleen and kidneydeficiency, such as Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Xuehai (SP 10) and Zigong (EX-CA 1). In the observation group, the acupoints were selected in terms of the physiological characteristics of follicular phase, ovulatory phase, luteal phase and menstrual phase. The main acupoints were Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3) and Xuehai (SP 10). The acupoints for benefiting kidneywere added in the follicular phase, such as Guanyuan (CV 4) and Dahe (KI 12), etc. The acupoints for regulatingand activating blood circulation were added in the ovulatory phase, such as Hegu (LI 4) and Taichong (LR 3), etc. The moxibustion was added for tonifying kidneyin the luteal phase, such as Qihai (CV 6) and Guanyuan (CV 4). The treatment was discontinued during the menstrual phase in the two groups. In the rest phases, acupuncture and moxibustion were given once every two days, 30 min each time. The overall efficacy, basal body temperature (BBT), follicular development, the average endometrial thickness and morphology as well as TCM syndrome score of spleen and kidneydeficiency were observed in the patients after 3-month menstrual periods. The adverse reactions were recorded in the two groups.

RESULTSIn the observation group, one case gave up the treatment due to the personal reason and another one stopped the treatment due to suffering from another kind of disease. 28 cases were included totally. In the control group, 3 cases were dropped out since attempting to receive in vitro fertilization-embryo transfer (IVF-ET) and 27 cases were finally included. The total effective rate was 92.9% (26/28) in the observation group, better than 85.2% (23/27) in the control group (<0.05). Except the endometrial morphology in the control group, after treatment, BBT, follicular development, the average endometrial thickness and morphology as well as TCM syndrome score were all improved apparently after treatment in the two groups (all<0.05). The improvements in follicular development, endometrial morphology and TCM syndrome score in the observation group were more obvious as compared with those in the control group (all<0.05). The incidence of the adverse reaction was 7.1% (2/28) in the observation group and was 3.7% (1/27) in the control group, indicating mild adverse reaction that could be relieved naturally.

CONCLUSIONSThe treatment with acupuncture and moxibustion achieves the significant efficacy on follicular maldevelopment differentiated as spleen and kidneydeficiency. Compared with conventional acupuncture-moxibustion therapy, the periodic therapy of acupuncture and moxibustion achieves the much better clinical efficacy.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective: To investigate the migration and invasion behaviors of Hep-2 after the targeted knockdown of yes-associated protein (YAP). Methods: Hep-2 cells were knock-downed for YAP by shRNA as YAP-shRNA group, Hep-2 treated with non-specific shRNA as YAP-NC group, and Hep-2 with no treatment as control. Glucose uptake and lactate production in the cells were examined to assess Warburg effect. The migration and invasion behaviors of cells in three groups were observed. The expressions of vimentin and E-cadherin were detected by RT-PCR and Western Blot. The statistical software GraphPad Prism 7.0 was used to analyze significance of data. Two tailed Student′ s t-tests was used to determine significance when only two groups were compared. P values of less than 0.05 was considered statistically significant. Results: Downregulation of YAP led to a obvious decrease in glucose uptake [(18.51±1.72)%] and lactate production [103.40±8.32] in Hep-2 cells compared with control [(41.20±1.11)% and 743.69±19.49, t=19.20 and 52.33, respectively, both P<0.01] and YAP-NC group [(39.60±0.78)% and 705.22±17.20, t=19.34 and 54.56, respectively, both P<0.01]. Compared with the control group (78.32±4.04) and YAP-NC group (77.28±3.11), the scratch healing ability of Hep-2 cells was significantly decreased in YAP-shRNA group (44.71±4.68). The P value was less than 0.01 (t=9.42 and 10.04). The number of cells with YAP-shRNA (33.30±4.19) passing through compartments was remarkable fewer than the control group (133.71±6.72) and YAP-NC group (126.32±4.21). The P value was less than 0.01 (t=21.96 and 27.13). The expression of E-cadherin protein in cells of YAP-shRNA group (6.16±0.11) was up-regulated compared with control (0.97±0.10, t=35.70, P<0.01) and YAP-NC group (1.13±0.09, t=36.28, P<0.01), while the expression of vimentin protein in cells of YAP-shRNA group (1.08±0.09) was down-regulated compared with control (5.67±0.12, t=29.91, P<0.01) and YAP-NC group (5.51±0.12, t=29.04, P<0.01). Conclusions The down-regulation of YAP in Hep-2 inhibits the migration and invasion of cells via suppressing Warburg and EMT program.
