Objective To explore the efficacy of hormone replacement therapy (HRT) for rheumatoid arthritis (RA).Methods The literature about HRT in the treatment of rheumatoid arthritis were searched.Eleven papers were subjected to a Meta-analysis and a heterogeneity test was conducted to evaluate the efficacy of HRT.Results HRT reduced the level of erythrocyte sedimentation rate (ESR) in RA patients (P=0.016),the SMD was-0.22(-0.40,-0.04); improved bone mineral density (BMD) in RA patients (P=0.022),the WMD was 2.83(0.41,5.26); decreased clinical parameters for disease activity evaluations of RA patients (P=0.048),the SMD was-0.19 (-0.38,0.00); decreased the level of C-reactive protein (CRP) in RA patients,the SMD was-0.08 (-0.37,0.21),but the difference was not statistically significant (P=0.591).Conclusion The findings from this Meta-analysis indicate that HRT can reduce the ESR level,improve clinical indexes and improve BMD level of RA patients.HRT may suppress disease activity and osteoporosis of RA patients,so it may be used as an auxiliary therapy in the treatment of RA.

For unresectable advanced hepatocellular carcinoma (HCC),besides sorafenib,alternative drugs and treatment modalities are required.Clinical studies of hepatic arterial infusion chemotherapy (HAIC),transcatheter arterial chemoembolization (TACE),and system chemotherapy have shown favorable efficacy and tolerance in advanced HCC patients.In addition,the potential efficacy of sorafenib combined with focal treatment is also an interesting issue.As more therapies become available,decision-making for treating advanced HCC becomes increasingly complex.In our opinion,diverse treatment modalities should be utilized for the best interest of patients.Based on predictive biomarkers,we should develop a precise patient stratification system to select suitable candidates for each treatment modality in future studies,as is useful for improving prognosis of patients with advanced HCC.

The establishment of quality evaluation of traditional Chinese medicine system that not only accords with Chinese medicine function characteristics but also is recognized as international medical circles, is an arduous task in urgent need of solving the current modernization of traditional Chinese medicine in the process of internationalization. It is difficult to evaluate atraditional Chinese medicine by detection of single active components in traditional Chinesemedicinewiththe western medicine quality controlmethod due to the overall effects of traditional Chinese drugs, the components of the overall diversity, targets, and the complexity of the interaction between components of unpredictable make the Long-term since, domestic and foreign scholars continue to explore and put forward a series of quality evaluation of traditional Chinese medicine to promote the development of traditional Chinese medicine. This article summarized the related academic ideas and developments to, providea new thought and perspective for the quality control of traditional Chinese medicine.

Objective To analyze the ultrasound features of ultrasonograpy-false-positive benign thyroid nodules in 37 cases. Methods With pathology results as the golden standard, thirty-seven patients with forty-six nodules were misdiagnosed as thyroid cancer by ultrasonography. The pre-operative diagnosis of ultrasonography were retrospectively reviewed and analyzed. Results Among forty-six thyroid nodules, twenty-one nodules had a diameter of 10.0 mm or smaller, while the other twenty-five nodules had a diameter of larger than 10.0 mm. In all forty-six thyroid nodules, the pre-operative ultrasonography found the majority of nodules with 3 or more than 3 malignant signs. The forty-six thyroid nodules showed solid (89.1%, 41/46), cystic-solid (10.9%, 5/46), marked hypoechogencity (87.0%, 40/46), ill-defined margin (56.5%, 26/46), calcification (76.1%, 35/46),microcalcification and macrocalcification), and taller-than-wide shape (30.4%, 14/46). The thyroid imaging reporting and data system (TI-RADS) lexicon was introduced to describe the lesions:forty-one nodules were categorized as TI-RADS 4c and 5 nodules were categorized as TI-RADS 5. On histology, these misdiagnosed thyroid nodules revealed severe fibrosis, hyalinization and calcification. The ultrasonic images were complicated and difficult to be differentiated from thyroid cancer. Conclusion Benign thyroid nodules with fibrosis, hyalinization, hemorrhage and calcification will lead tothe significant change on lesions' morphology, echo intensity and internal structure. When the benign and malignant signs ultrasound co-existed in a single thyroid nodule, benign thyroid nodules might be easily misdiagnosed as thyroid cancer.

Objective To evaluate the early effects on insulin resistance following sleeve gastrectomy with ileal interposition duodenojejunal bypass operation.Methods From Jun.2010 to Sep.2011,37 cases of type 2 diabetes mellitus patients [23 male,14 female; mean age (45.2 ± 2.4) years,mean BMI (21.7 ± 1.8) kg/m2] underwent sleeve gastrectomy with ileal interposition duodenojejunal bypass operation.Fasting plasma glucose(FPG),fasting insulin(FIns),body mass index(BMI),and homeostatic model assessment for insulin resistance (HOMAIR) were detected before surgery and on the 10th,20th,30th,and 60th day after surgery.Results The level of FPG was (6.8 ± 0.7) mmol/L,(7.2 ± 0.6) mmol/L,(6.9 ± 0.3) mmol/L respectively on the 10th,20th,and 30th day after surgery,significantly lower than that before surgery[(10.2 ±0.4)mmol/L].The difference had statistical significance (P ＜ 0.05).The level of Fins was (6.3 ± 1.1) mIu/L,(7.1 ± 1.3) mIu/L,and (7.3 ± 1.6) mIu/L respectively on the 10th,20th,and 30th day after surgery,significantly lower than that before surgery[(12.6 ± 1.4)mIu/L].The difference had statistical significance (P ＜ 0.05).The level of lnHOMA-IR was 0.7 ± 0.2,0.9 ± 0.5,and 0.8 ±0.4 respectively on the 10th,20th,and 30th day after surgery,significantly lower than that before surgery (1.8 ±0.6).The differenc had statistical significance(P ＜0.05).However,the change of BMI was not obvious between before surgery and on the 10th,20th,and 30th day after surgery.The difference had no statistical significance (P ＞ 0.05).on the 60th day after surgery,the level of FPG,Fins,lnHOMA-IR and BMI was significantly reduced compared with that before surgery.The difference had statistical significantce(P ＜0.05).Conclusion After sleeve gastrectomy with ileal interposition duodenojejunal bypass operation,the early improvement of insulin resistance occurs rapidly and it is iadependent of the loss of BMI.

Objective The expression of anti-inflammatory cytokine interleukin(IL)-10 in protrusion and extrusion tissue of intervertebral disc and its correlation with clinical features.Methods The specimens were from 30 cases of disc herniation in single level.The patients were enquired about the medical histories and evaluated by JOA index preoperation before operation,which were all completed by one trained doctor.The contents of IL-10 in the inter=43vertebral disc were detected by enzyme-linked immunosorbent assay after operation.Results The level of IL-10 had no statistical significance between protrusion and extrusion tissue of intervertebral disc (t =0.032,P =0.725).Patient's JOA index has negative correlation with IL-10(r =-0.377,P =0.040),and positive correlation with Patient's history (r =0.449,P =0.013).Conclusion Protrusion and extrusion tissue of intervertebral disc have abilities of excreting anti-inflammatory cytokine IL-10.The level of cytokine has correlation with patient's clinical features.
