Objective To observe he effects of new Tangshenkang on α-SMA and E-cadherin of human renal tubular epithelial cell HK-2 in high concentrations of glucose; To explore the mechanism of new Tangshenkang on the prevention and treatment of diabetic renal fibrosis. Methods The HK-2 cells were cultured and divided into control group, high glucose group, animal serum control group, new Tangshenkang low-, medium-, and high-dosage group. After medicine intervention, cell proliferation was tested by MTT assay, and contents of α-SMA and E-cadherin were observed by ELISA assay. Results Compared with control group, α-SMA of HK-2 cultured with high glucose was much notable, but the content of E-cadherin significantly decreased, with statistical significance (P<0.05). The content of α-SMA of HK-2 cultured with new Tangshenkang decreased, and the content of E-cadherin increased; cell proliferation was markedly inhibited in culture medium supernatant of HK-2 cells cultured with high glucose plus new Tangshenkang compared with only high glucose, with statistical significance. Conclusion New Tangshenkang can inhibit cell proliferation and epithelial-myofibroblast transdifferentiation of HK-2 cell induced by high glucose, and prevent the development of diabetic renal fibrosis to a certain extent.

OBJECTIVE: To investigate the liver T1rho values for detecting fibrosis, and the potential impact of fatty liver on T1rho measurements. MATERIALS AND METHODS: This study included 18 healthy subjects, 18 patients with fatty liver, and 18 patients with liver fibrosis, who underwent T1rho MRI and mDIXON collections. Liver T1rho, proton density fat fraction (PDFF) and T2* values were measured and compared among the three groups. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the T1rho values for detecting liver fibrosis. Liver T1rho values were correlated with PDFF, T2* values and clinical data. RESULTS: Liver T1rho and PDFF values were significantly different (p < 0.001), whereas the T2* (p = 0.766) values were similar, among the three groups. Mean liver T1rho values in the fibrotic group (52.6 ± 6.8 ms) were significantly higher than those of healthy subjects (44.9 ± 2.8 ms, p < 0.001) and fatty liver group (45.0 ± 3.5 ms, p < 0.001). Mean liver T1rho values were similar between healthy subjects and fatty liver group (p = 0.999). PDFF values in the fatty liver group (16.07 ± 10.59%) were significantly higher than those of healthy subjects (1.43 ± 1.36%, p < 0.001) and fibrosis group (1.07 ± 1.06%, p < 0.001). PDFF values were similar in healthy subjects and fibrosis group (p = 0.984). Mean T1rho values performed well to detect fibrosis at a threshold of 49.5 ms (area under the ROC curve, 0.855), had a moderate correlation with liver stiffness (r = 0.671, p = 0.012), and no correlation with PDFF, T2* values, subject age, or body mass index (p > 0.05). CONCLUSION: T1rho MRI is useful for noninvasive detection of liver fibrosis, and may not be affected with the presence of fatty liver.

OBJECTIVETo evaluate the clinical efficiency and safety of two-micron laser resection of the prostate-tangerine technique (TmLRP-TT) for the treatment of large-volume ( > 70 ml) prostate in patients with benign prostatic hyperplasia (BPH).

METHODSThis retrospective analysis included 80 BPH patients with the prostatic volume larger than 70 ml, all treated by TmLRP-TT. We comparatively analyzed the levels of hemoglobin and serum sodium before and after surgery, recorded intra- and post-operative com- plications, and followed up the patients at 6 and 12 months after operation for International Prostate Symptom Score (IPSS), quality of life (QOL), maximum flow rate (Qmax), and postvoid residual urine volume (PVR).

RESULTSAll the operations were successfully completed. The mean hemoglobin decreased (0.68 +/- 0.43) g/dl intraoperatively, but no apparent reduction was observed in serum sodium. Lower urinary tract symptoms were relieved significantly in all the cases. At 12 months after surgery, IPSS was decreased by 73.89% as compared with the baseline (20.03 +/- 6.9 vs 5.23 +/- 3.59), QOL by 64.55% (4.09 +/- 1.19 vs 1.45 +/- 1.36), and PVR by 79.30% (97.31 +/- 57.90 vs 20.14 +/- 24.20 ml), while Qmax increased by 140.42% ([8.04 +/- 3.62] vs [19.33 +/- 3.28] ml/s). The incidence of complications was low either intraoperatively or during the 12 months after operation.

CONCLUSIONTmLRP-TT is a safe and effective surgical endoscopic approach to the treatment of large-volume prostate in BPH patients.

Objective To assess the income status of primary care providers and to explore the determinants of income in a county of Dali. Methods In August 2016, the questionnaire was employed to collect the data of income status of 191 rural health workers and 217 village doctors in the county. Results Through the study, we found that the income of rural health workers in the county was 34, 000 (26, 000, 46,000) yuan with a satisfaction rate of 62.3% (95% CI 55.4%～69.2%) and no change (74.7%) was seen in the income among majorities after implementing the Zero Mark-up Policy for essential medicines. For the village doctors, the income was 20,000 (15,000, 24,000) yuan with a satisfaction rate of 40.6% (95% CI 34.0%～47.1%) and a fall of the income was found in more than half of the doctors after the implement of the policy. Conclusion Health care workers in towns are quite satisfied with their income whereas those in health stations of villages are not content, compared with the average income at the national level. We should increase government's investments on grass-root healthcare team, improve the incentive pay plans and promote the integrated management of health facilities in towns and villages.

Paf1 complex was identified in yeast and characterized to function in transcription and its related events. We identified the Drosophila homological components of paf1, CDC73 and RTF1 of paf1 complex. The genes encoding Drosophila paf1, CDC73 and RTF1 were cloned and expressed. With the purified recombinant proteins of truncated components of paf1 complex, antibodies against the Drosophila paf1, CDC73 and RTF1 were generated. These antibodies have been shown to be able to detect the endogenous paf1 subunits as well as their human counterparts in the HeLa extract. On Drosophila polytene chromosomes, these antibodies have been demonstrated to locate the paf1 complex at actively transcribing sites, which co-localized with phosphorylated RNA polymerase II, indicating that paf1 complex in Drosophila is involved in transcription or the events coupling with transcription.

OBJECTIVETo explore the efficacy on knee osteoarthritis (KOA) treated with different acupuncture methods at different stages.

METHODSOne hundred and eighty cases of KOA were divided into stagnation stage, fascia cramp stage and tendon lesion stage according to the condition of disease, 60 cases in each stage. Each stage was randomized into a staging treatment group and an electroacupuncture (EA) group, 30 cases in each one. In the staging treatment group, acupuncture at the tendon points of meridians and electric thermal needling method were adopted for the cases at the stagnation stage; the small needle-knife therapy and bleeding method were used for the cases at the fascia cramp stage; and the electric thermal therapy with thick silver needles was applied for the cases at the tendon lesion stage. In the EA group, EA was applied for the cases of all the three stages at Liangqiu (ST 34), Xuehai (SP 10), Yanglingquan (GB 34), etc.

RESULTSThe total effective rate was 96.1% (87/90) in the staging treatment group and was 91.1% (82/90) in the EA group, without significant difference in comparison (P > 0.05). The controlled and remarkably effective rate (88.9%, 80/90) in the staging treatment group was higher apparently than (62.2%, 56/90) in the EA group (P < 0.001). And in the EA group, with the disease progression and the further disease stages, the controlled and remarkably effective rate was reduced. After treatment, the scores of symptoms and signs were decreased in both groups (both P < 0.001), the improvement in the staging treatment group was superior to that in the EA group (P < 0.001).

CONCLUSIONThe different acupuncture methods at the three stages improve obviously the clinical effect and are highly targeted. The mechanism of the three stages on "meridian muscle region pathology" and the treatment based on the disease stages can be the effective approach to KOA.

OBJECTIVETo investigate the major risk factors for congenital heart disease (CHD) in Chinese neonates and to provide a reference for the prevention of CHD.

METHODSA literature search was performed to collect the case-control studies on the risk factors for CHD in Chinese neonates published in 2001-2016. The relevant data were extracted accordingly. The quality of included studies was assessed by Newcastle-Ottawa Scale. Sensitivity analysis was conducted using different models to analyze the same data. The publication bias was assessed by Egger's test.

RESULTSA total of 17 case-control studies involving 2 930 cases and 4 952 controls were included. The Meta analysis showed that the major risk factors for CHD in Chinese neonates were as follows: mother with advanced age (OR=2.649, 95%CI: 1.675-4.189), cold or fever (OR=4.558, 95%CI: 2.901-7.162), medication use in early pregnancy (OR=3.961, 95%CI: 2.816-5.573), passive smoking (OR=2.766, 95%CI: 1.982-3.859), abnormal childbearing history (OR=2.992, 95%CI: 1.529-5.856), noise exposure (OR=3.030, 95%CI: 1.476-6.217), radiation exposure (OR=2.363, 95%CI: 1.212-4.607), decoration (OR=4.979, 95%CI: 3.240-7.653), gestational diabetes (OR=5.090, 95%CI: 3.132-8.274), and pet raising (OR=2.048, 95%CI: 1.385-3.029).

CONCLUSIONSMothers with advanced age, cold or fever, medication use in early pregnancy, passive smoking, abnormal childbearing history, noise exposure, radiation exposure, decoration, gestational diabetes, and pet raising may increase the risk of CHD in Chinese neonates.

OBJECTIVETo investigate clinicopathologic features of solitary plasmacytoma of bone (SPB) and the role of immuno-phenotype and immunoglobulin gene rearrangement detection in the diagnosis and differential diagnosis of SPB.

METHODSA total of 21 cases of SPB were selected during a period from 1990 to 2008. A retrospective clinicopathologic study and immunohistochemistry (EnVision or EliVision methods) of 17 antigens were performed. In addition, universal IgH (FR3A/LJH/VLJH) primers and BIOMED-2 PCR multiplex tubes were used for IgK and IgL rearrangement analysis.

RESULTSThe age of patients ranged from 36 to 72 years with a media of 50 years. Axial skeleton was the most common site of involvement, accounting for 66.7% of the cases (14 of 21), followed by the extremities of 33.3% (7 cases). Low serum level of M-components was found in 5 cases, including two of IgG type (21.4 g/L) and three of IgA type. Clinical manifestations were closely related to the anatomic sites involved, such as pain due to bone destruction, symptoms and signs caused by compression of spinal cord or nerve root, and pathological fracture. All cases presented as a solitary osteolytic lesion. According to the histological grading criteria, grade I tumor was seen in 12 of 21 cases (57.1%). The remaining were grade II (5 cases, 23.8%) and grade III (4 cases, 19.0%). Immunohistochemically, the neoplastic cells expressed two or more plasma cell antigens, including CD138, CD38 and PC, but no CD19 and CD20. CD79a expression detected in 23.8%(5/21) of the cases. Expression of CD56, CD27 and CD44v6 were 57.1% (12/21), 15.0% (3/20) and 23.8% (5/21), respectively. Follow-up data were available in 12 of the 21 patients (57.1%). Five patients were alive and 7 died. Three patients developed multiple myeloma (MM) and died of the tumor.

CONCLUSIONSSPB is a rare tumor with bone pain as the most common presenting symptom due to bone destruction. The diagnosis of EMP can only be established after exclusion of an extramedullay invasion by MM. Immunophenotype and IgH gene rearrangement analysis play important roles in the diagnosis of SPB.

OBJECTIVETo evaluate the clinical effects of Chinese medicine (CM) on acute myocardial infarction (AMI) with a prospective cohort study.

METHODSA total of 334 AMI patients from January 2007 to March 2009 were consecutively enrolled, and were assigned to a treatment group (169 cases) treated with combined therapy (CM for at least one month and Western medicine) and a control group (165 cases) with Western medicine alone. Clinical data including age, gender, smoking, medical history, infarction area, heart functional classification, CM syndrome scores, blood-stasis syndrome score, primary end-point (death, nonfatal myocardial infarction, and revascularization) and secondary end-point (ischemic stroke, rehospitalization due to angina, heart failure and shock), were collected. CM syndrome scores, blood-stasis syndrome score, primary end-point and secondary end-point were collected during the 6-month follow-up. Kaplan-Meier method was used for the survival analysis. The multifactor analysis was analyzed by Cox proportional hazards regression.

RESULTSAt the end of 6-month the CM syndrome score and bloodstasis syndrome score in the treatment group were lower than those in the control group (P<0.01), especially the symptoms of chest pain, spontaneous perspiration and insomnia. Rehospitalization rate due to angina during the 6-month follow-up in the treatment group (2.96%) was lower than that in the control group (7.88%, P<0.05). Kaplan- Meier survival curve showed that event-free cumulated survival of rehospitalization due to angina during the 6-month follow-up in the treatment group was higher than that in the control group (Log rank 4.700, P=0.03). Cox regression analysis showed that heart dysfunction [hazard ratio (HR)=1.601, 95% CI=1.084-2.364, P=0.018] and diabetes mellitus (HR=1.755, 95% CI=1.031-2.989, P=0.038) were hazard factors to end-point, whereas CM (HR 0.405, 95% CI=0.231-0.712, P=0.002), percutaneous coronary intervention (PCI, HR=0.352, 95% CI=0.204-0.607, P<0.001) and angiotensin converting enzyme (ACE) inhibitors (HR=0.541, 95% CI=0.313-0.936, P=0.028) were protective factors.

CONCLUSIONSCM therapy could decrease CM syndrome scores and blood-stasis syndrome score, reduce the rehospitalization rate during 6-month follow-up due to angina. Heart dysfunction and diabetes mellitus were hazard factors to end-point, whereas CM, PCI and ACE inhibitors were protective factors.
