Objective To investigate the relationship between C-peptide and artherosclerosis in lower ex-tremity in patients with type 2 diabetes. Methods Two hundred and fourteen type 2 diabetic patients were included in this retrospective study. They were divided into two groups:type 2 diabetes with artherosclerosis in lower extremi-ty in 123 cases and type 2 diabetes without artherosclerosis in lower extremity in 91 cases. Their medical history and the laboratory data were collected such as fasting serum C-peptide levels and postprandial serum C-peptide levels of 1 hour, 2 hours and 3 hours, glycated hemoglobin (HbA1c) and so on. Results Compared with artherosclerosis group in lower extremity, the age, duration of diabetes, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), glycated hemoglobin and smoking rate were significantly higher in type 2 diabetes without artherosclero-sis in lower extremity (P < 0.05). However, the high density lipoprotein cholesterol (HDL-C) was much lower in the last group (P<0.05). There were no significant differences in the other indicators between the two groups (P>0.05). Logistic regression analysis showed that fasting and postprandial (1 hour, 2 hours and 3 hours)serum C-pep-tide levels were all negatively related to artherosclerosis in lower extremity (OR 0.524,P = 0; OR 0.440, P = 0;OR 0.688, P=0;OR 0.795, P=0). Conclusions Serum C-peptide level may be an independent associated fac-tor with artherosclerosis in lower extremity in type 2 diabetes.

Objective To investigate the expression of matrix metalloproteinase-2(MMP-2) in the VX2 hepatic tumor.Methods 30 New Zealand white rabbit VX2 liver carcinoma models(all the tumors were verified by histopathology)were set up.The expressions of MMP-2 in 30 cases of VX2 tumor tissues and their pericarcinomatous tissues and normal hepatic tissues in 20 cases were detected by immunohistochemical staining with SP method at 2.5 weeks after implantation.The cell number of MMP-2 positive expression was counted by immunohistochemical stain.Results According to immunohistochemical results,the positiveness of MMP-2 was 86.7%(26/30) in tumor tissues and 53.3%(16/30) in pericarcinomatous tissues and no expressions of MMP-2 in normal hepatic tissues.The expression of MMP-2 were mainly in the tumor cytoplasm and intercellular substance,and also in the part of the tumor thrombi,the bile vessel epithelial cell and vascular endothelial cell.Conclusion The features of the expression of MMP-2 are similar to that of human HCC,and this model is a real animal model for clinical MMP-2 study of human HCC.

Objective To explore the effect of transcatheter arterial chemoembolization ( TACE ) on the apoptosis proteins fas,bax,and bcl-xl in hepatocellular carcinoma ( HCC ) . Methods Sixty-three cases with HCC proved by histopathologically were studied, which included 42 cases treated with surgical resection alone,and 21 cases underwent TACE . The expressions of fas,bax,bcl-2 and bcl-xl were detected with immunohistochemical SP method .Results The positive rate of fas was 47.62% ( 10/21 ) in HCCs treated with TACE,and 21.43%(9/42) in those treated with surgical resection alone, there was significantly difference between the two groups(?0.05). Conclusion TACE can increase the expression of fas and decrease the expression of bcl-xl, it can increase the rate of apoptosis of HCC, make HCC lesion contract. The effect of TACE to bax need more research.

Objective To identify mutations in the OSMR gene in a pedigree with familial primary cutaneous amyloidosis (FPCA).Methods Clinical data were collected from a pedigree with FPCA.Peripheral blood samples were obtained from the proband,his 19 relatives,and 50 unrelated healthy human controls.Genomic DNA was extracted from these blood samples,and subjected to PCR for the amplification of 18 encoding exons and their flanking sequences of the OSMR gene followed by DNA sequencing.Results A heterozygous missense mutation c.2081C ＞ T,which leads to the substitution of proline by threonine at position 694,was detected in the OSMR gene of the proband and his affected relatives,but not in unaffected relatives or healthy controls.Conclusion The heterozygous mutation p.P694L in the OSMR gene may cause the clinical phenotype of FPCA in this family.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

The paper is a systematic review on the efficacy of acupuncture manipulation on primary dysmenorrhea. Ten medical literatures database at home and abroad were retrieved, including CNKI, VIP, CBM, WANFANG, MEDLINE, Cochrane, CENTRAL, CINAHL PLUS, EMBASE, AMED and PsycINFO, as well as 6 clinical trial registration platforms. All of randomized controlled trials (RCTs) on primary dysmenorrhea treated with different acupuncture manipulations were collected. The data were extracted by two persons. Finally, RevMa 5.3 software was used for statistical analysis. Totally, 5 148 pieces of literature were retrieved and 8 pieces on RCTs were screened with 644 cases included. According to the results of statistical analysis on the total effective rate and other indicators of pain degree, it was showed that the effects of the manipulation with filiform needle, deep puncture with strong stimulation, and specific reinforcing and reducing needling technique were better than those without manipulation applied or with shallow puncture and weak stimulation and even needling technique in the treatment of primary dysmenorrhea. It is believed initially that acupuncture manipulation contributes to the improvement of the therapeutic effects of primary dysmenorrheal, but much higher quality studies are required for the further confirmation. Protocol registration number:PROSPERO:CRD42016038515.

OBJECTIVETo evaluate the effects of needling depth on clinical efficacy of lumbar disc herniation (LDH).

METHODSTen electronic databases, including China National Knowledge Infrastructure (CNKI), VIP Database, Chinese Biomedical Literature Database (CBM), Wanfang Database, MEDLINE, CENTRAL, CINAHL PLUS, AMED, Embase, PsycINFO, and 6 registry platforms of clinical trials were searched. All randomized controlled trials (RCTs) that compared the effect of needling depth on clinical efficacy of LDH were collected; in addition, the reference lists of the studies included were hand searched. Data were extracted independently by two reviewers. RevMan 5.3 was applied to carry out statistical analysis.

RESULTSTotally 8 716 articles were retrieved, and 10 RCTs were included after screening, involving 1 116 patients. The results showed the effects of deep acupuncture onrelievingpain, reducing the Oswestry disability index (ODI), improving total effective rate and Japanese Orthopaedic Association (JOA) were superior to those of shallow acupuncture in patients with LDH.

CONCLUSIONIt is preliminarily indicated that deep acupuncture is helpful to improve the therapeutic effect of LDH; however, due to the low research quality and small sample size, the evidence is insufficient, and more high-quality researches are needed to further confirm the results.

The effects of(arrival of) on acupoint effects in patients with primary dysmenorrhea (PD) were evaluated.Ten literature databases,including China National Knowledge Infrastructure (CNKI),VIP Database,Wanfang Database,Chinese Biomedical Literature Database (CBM),Cochrane Library CENTRAL,MEDLINE,Embase,AMED, CINAHL Plus,PsycINFO were selected.In addition,5 registers of ongoing trials,the reference lists of included articles and grey literature website OpenGrey were added.The search time was from date of database establishment to August 2016;no restrictions were made on language or status of publication.All randomized controlled trials (RCTs) and quasi-randomized controlled trials (q-RCTs) which compared the effects ofand non-on PD or compared the effects of differentelements on PD were included.The research quality was assessed according to Cochrane bias risk evaluation tool 5.1.0.The RevMan 5.3.5 was applied for quantitative analysis if insignificant clinical heterogenicity with≤ 75%,otherwise the results was summarized by qualitative analysis.As a result,6 RCTs involving 645 patients were included.Because of considerable clinical heterogeneity,only qualitative analysis was performed,which indicated ① acupuncture could reduce pain and anxiety regardless of,and the effects ofon pain relief were superior or equivalent to that of none-,and the effects ofon anxiety relief were similar to that of none-;② the more intensity ofand higher number of acupoints selected,the better effects on pain alleviation,symptom relief and pain duration;③ the higher rate ofhad a better acupoint effect on alleviating anxiety,but was not on pain relief;④appeared early and propagated to affected area could lead to faster onset on pain relief;⑤ the effects on relieving pain and symptoms was better when warm sensation inorreaching affected area.Due to the few number,low quality and potential bias of included studies,it was not sufficient to draw clear conclusion regarding the effects ofon PD patients.This study protocol was registered in PROSPERO (CRD42016038518).
