Objective To investigate the prevalence of mutation in the locus 306 of embB gene in multi-drug resistant (MDR) Mycobacterium tuberculosis (TB) and evaluate the prospects for using it as a molecular marker to detect MDR-TB.Methods The 291 strains enrolled in this study were from the reference laboratory of Shanghai municipal centers for disease control and prevention, all of which had been tested for drug susceptibility.Mutation in embB 306 was screened both by amplification refractory mutation system (ARMS) and DNA sequencing.The mutation frequencies of embB 306 in the sample groups varied in drug resistance were statistically analyzed.Results 38(51.4% ) of the 74 MDR-TB were embB 306-mutant (X2 =93.8,P＜0.01).Of the 24 TB resistant to at least two drugs but not MDR, 9(37.5% ) were embB 306 mutant (X2 =60.1 ,P＜0.01 ).But only two(4.9% ) embB 306-mutant strains were found in 41 strains resistant to only one drug (X2 =6.8,P=0.0093).None embB 306-mutant strains were found in 152 pansensitive strains.The specificity of using embB 306 as a molecular marker for detecting multi-drug resistant TB was 94.9% (206/217).Conclusions As a molecular marker for screening drug resistant TB,especially MDR-TB, the gene locus embB 306 shows a relatively high sensitivity and specificity, promising a sound future for its application in clinics to realize fast screening of patients infected with MDR-TB and to provide evidence for appropriate medication.

Objective: To summarize the peri-operative management experience of pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A total of 56 CTEPH patients received PEA in our hospital from 2015-01 to 2016-11 were retrospectively analyzed. Our study was focused on the medication in respiratory and circulatory system during ICU stay, peri-operative application of vasoactive drug and target drug to pulmonary hypertension (HP), usage of ventilators, mechanical assisted devices and other management experiences. Results: No peri-operative death occurred. There were 2/56 (3.6%) patients with lung reperfusion, 2 (3.6%) with PH crisis. Compared with pre-operation, the post-operative pulmonary artery hemodynamics parameters were improved as right heart catheter measured pulmonary artery systolic pressure (PASP) decreased from (85.05±22.40) mmHg to (36.83 ±17.21) mmHg and pulmonary vascular resistance decreased from (773.84±342.95) dyn·s·cm-5 to (293.59±214.95) dyn·s·cm-5. Post-operative oxygen saturation was maintained at (95-100) % in all patients. Echocardiography found that PASP from pre-operation (85.03±25.78) mmHg decreased to (39.44±19.24) mmHg at follow-up period, P<0.01.Conclusion: A comprehensive peri-operative management of PEA was helpful to improve pulmonary hemodynamics in CTEPH patients; meanwhile, effective prevention and treatment of severe complication could obviously reduce peri-operative mortality.

Objective To analyze the predictive value of dynamic changes in key factors of the toll-like receptor(TLR)/nuclear factor-κB(NF-κB)signaling axis during the perioperative period for bone infection inpatients with open fractures.Methods A total of 55 patients with open fractures who developed bone infections during the perioperative period were selected as infection group,and 110 patients with open fractures who did not develop infections during the same period were selected as non-infection group.Clinical data,pre-and post-operative serum levels of routine inflammatory markers[C-reactive protein(CRP),interleukin-6(IL-6)and procalcitonin(PCT)]and key factors of the TLR/NF-κB signaling axis(TLR4,NF-κB)were compared between the two groups.Logistic multivariate regression analysis was used to identify risk factors for bone infection during the perioper-ative period in patients with open fractures.Receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value of the absolute change(the absolute value of the changes was expressed as △)in the levels of key factors of the TLR/NF-κB signaling axis before and after surgery for bone infection,and these results were compared with the predictive value of routine inflammatory markers.A nomogram prediction model was developed based on the identified risk factors,and its value in predicting perioperative bone infection was analyzed.Results The time from fracture to surgery and the duration of surgery were significantly longer,and the proportion of Gustilo type Ⅲ fractures and wounds with a depth ≥2 cm was significantly higher in the infection group compared to the non-infection group(P＜0.05).At 24 h after surgery,serum CRP,IL-6,PCT,TLR4 and NF-κB levels in two groups were significantly higher than before surgery,and serum CRP,IL-6,PCT,TLR4 as well as NF-κB levels and their changes in bone infection group were significantly higher than those in the non-infection group(P＜0.05).Logistic regression analysis indicated that time from fracture to surgery,surgical duration,Gustilo type Ⅲ and wound depth ≥2 cm,and △ CRP,△ IL-6,△ PCT,△TLR4 as well as △NF-κB were risk factors for perioperative bone infection in patients with open fractures(P＜0.05).ROC results showed that the area under the curve(AUC)of △CRP,△IL-6,△PCT,△TLR4 and △NF-κB for predicting bone infection were 0.786,0.833,0.772,0.826 and 0.736,respectively.ROC curve showed that the AUC of the nomogram prediction model for periop-erative bone infection was 0.893(95％CI,0.834 to 0.952),indicating high predictive efficacy.The decision curve showed that the nomogram prediction model had a significant positive net benefit,and it had good clinical utility in predicting the risk of bone infection.Conclusion The dynamic changes of key factors of TLR/NF-κB signal axis in perioperative period of patients with open frac-ture have certain predictive value for postoperative bone infection.The nomogram prediction model based on the above influencing factors has good predictive value and positive clinical net benefit.

Objective To compare the efficacy and safety of 3 rivaroxaban regimen in patients with venous thromboembolism (VTE).Methods This is a retrospective study.Thirty three inpatients with VTE received rivaroxaban were divided into 3 groups,in which 16 patients were treated with 15 mg rivaroxaban twice daily for 21 days then followed by 20 mg once per day till 3 months (group 1),9 patients were treated with 20 mg rivaroxaban once daily for 3 months (group 2),8 patients were treated with 10 mg rivaroxaban once daily for 3 months.The reduction rate of D-Dimer on the third therapy day,the duration of D-Dimer normalization and hospital stay as well as symptom remission,the imaging assessment results after three months treatment,rate of recurrent VTE,bleeding,liver and kidney function were compared among the 3 groups.Results The reduction rates of D-Dimer on the third therapy day were significantly higher ((46.12±15.42)％ vs.(26.59±8.11)％ and(25.55 ± 14.00)％,P =0.02,P=0.01),and the duration of D-Dimer normalization was significantly shorter ((17.9 ±7.7) days vs.(24.1 ±5.1) days and (26.3 ± 6.2) d,P =0.03,P ＜ 0.01) in group 1 than in group 2 and 3.There was one recurrent deep-vein thrombosis in group 3,one non-major bleeding in group 1 and group 3.Major bleeding or liver and kidney dysfunction were not observed in these patients.Conclusions Venous thromboembolism can be safely and effectively treated by rivaroxaban,and does of 15 mg twice daily for 21 days followed by 20 mg once daily for 3 months are superior to the other 2 tested therapy regimen in this patient cohort.

AIM: To observe the effects of rapamycin pregnancy intervention on cognitive function of autism model in rat offspring. METHODS: Fourteen pregnant rats were randomly divided into normal group (n = 3), model group (n = 4), rapamycin (RAPA) control group (n =3) and intervention group (n = 4). The model group and intervention group were i.p. injected with sodium valproate 600 mg/kg at embryonic day (E) 12.5 to establish autism model in rat offspring. RAPA control group and intervention group were i.g. given RAPA 4 mg/kg every day from the 13th day of gestation until the offspring rats were weaned at 23 days. After the birth of the above four groups of pregnant rats, 15, 27, 21 and 26 offspring male rats were selected to conduct behavioral tests to identify the model. Then, paw withdrawal mechanical threshold (PWMT), tail flick latency (TFL) evoked under different light intensity and learning and memory function of offspring rats were further detected. RESULTS: Rat offspring in the model group had lower growth and development indexes and exploratory behavior ability, but stronger repetitive stereotyped behavior compared with the normal group (P < 0.05), while the indexes between the intervention group and model group were reversed (P < 0.05). The model group had higher PWMT than normal group (P < 0.01) and the PWMT of intervention group was lower than that of model group (P < 0.01). The TFLs of rats in 4 groups showed a timed dose-response relationship (TDRR, P < 0.01), that is, TFLs were shortened with the increase of light intensity. The TDRR curve of model group shifted to right compared with normal group (P < 0.01) and intervention group shifted to left compared with model group (P < 0.01). At the light intensity of Focus 34, 51 and 76, the TFLs of model group were longer than those of normal group (P < 0.01) and intervention group had shorter TFLs compared with model group (P<0.01). In spatial probing trial of Morris water maze test, the platform crossover number in model group was less than that in normal group (P<0.01) and that in intervention group was more than model group (P < 0.05). CONCLUSION: RAPA intervention during pregnancy may alleviate behavior disorder, pain tolerance and memory function of autism model in rat offspring to some extent.

With the aging of the global population， osteoporosis （OP） is becoming a major public health concern worldwide. Currently， the commonly used anti-osteoporosis drugs in clinical practice have limited application due to many side effects. Therefore， developing more effective and safer strategies for the prevention and treatment of OP has become a research focus in this field. In recent years， the clinical efficacy and advantages of traditional Chinese medicine （TCM） in treating OP have been gradually recognized. With the deepening pharmacological research on TCM for OP prevention and treatment， it is found that the active ingredients of Scutellaria baicalensis can promote bone formation or inhibit bone resorption by regulating signaling pathways， including Wnt/β-catenin， osteoprotegerin （OB）/receptor activator of nuclear factor-κB ligand （RANKL）/RANK （OPG/RANKL/RANK）， and bone morphogenetic protein 2 （BMP-2）/Smad， mitogen-activated protein kinase （MAPK）， and mammalian target of rapamycin （mTOR）. However， existing research on active ingredients of S. baicalensis for OP treatment is scattered， making it difficult for scholars to gain a systematic understanding of its research and application. This review summarized the literature on the active ingredients of S. baicalensis in OP treatment worldwide， clarified their mechanisms of action， and explored some issues， providing references for the integration of TCM in OP prevention and treatment.
