Endometrial receptivity is the key for embryo implantation. Improving the receptivity of the endometrium so that the endometrium and the embryo tend to synchronize is the key research field of reproductive medicine in recent years. Traditional Chinese Medicine could improve endometrial receptivity from the aspects like morphology, ultrasound, hormone and receptor expression, molecular biology level, and gene level. It plays a unique role in enriching the expression of pinocytosis, improving uterine artery blood flow, and increasing sensitivity of female progesterone receptor, adjusting related factors and gene expression.

Psoriasis is a non-infectious chronic inflammatory skin disease. It′s acknowledged that interleukin (IL)-17 signaling pathway dominantly drives the development of psoriasis. Recently, the role of neuro-immune axis in psoriasis has attracted widespread attention. Lidocaine, a local anesthetic, has ability to block the conduction of nerve impulses, while its therapeutic efficacy on psoriasis remains to be confirmed. Here, we evaluated the therapeutic efficacy of topical application of compound lidocaine cream (LIDO) on imiquimod (IMQ)-induced mouse psoriasis model. Animal welfare and experimental procedures follow the regulations of the Ethics Committee of China Pharmaceutical University. The psoriasis area and severity index (PASI) scoring was used to evaluate the severity of psoriasis-like symptoms. Hematoxylin-eosin staining was used to examine histopathological changes and epidermal thickness was measured. Ki67 immunofluorescence staining was used to evaluate the proliferation of keratinocytes. The relative mRNA expression of inflammatory cytokines (including Il17, Il22, Il23 and Il36) in skin was measured by real-time quantitative PCR. Results show that IMQ-induced increases in the PASI score, epidermal thickness, number of Ki67⁺ cells and the mRNA expression of inflammatory cytokines are significantly alleviated by topical application of LIDO, whose therapeutic efficacy is also better than that of the positive control drug calcipotriol. Our study suggests that LIDO could be used for psoriasis treatment.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel, located on cell membranes. TRPV3 is extensively expressed in various organs such as skin, brain, dorsal root ganglia, heart and colon. It's reported that TRPV3 involves in many physiological processes including sensation, skin barrier formation, hair growth and vasodilatation, and pathological processes like pruritus, cutaneous inflammatory disease and cancer. TRPV3 can respond to innoxious warm stimulation (≥ 33 ‍℃‍), endogenous substances (e.‍g., farnesylpyrophosphate) and exogenous small molecules (e.g., carvacrol, camphor and 2-APB). Recently, several natural or synthetic small molecules (e.g., osthole, 74a and dyclonine) have been shown to suppress TRPV3 activity, accompanying with therapeutic efficacy in animal models of diseases, which suggests the potential of TRPV3 as drug target. This paper reviews the research progress on the structure, physiological functions, related diseases and modulators of the TRPV3 channel to provide theoretical references for the future study on TRPV3 channel.

Objective: To investigate the relationship between Bilirubin blood lipid comprehensive index and ifbrinogen (FIB) to severity of coronary lesions in patients with coronary artery disease (CAD).
Methods: A total of 324 patients with angiography (CAG) conifrmed diagnosis were divided into 2 sets of groups.①By CAG examination, the patients were divided into 2 groups: CAD group,n=262 and Non-CAD group,n=62.②By Gensini scoring system, the patients were divided into 4 quartile groups: 1st quartile group,n=58, 2nd quartile group,n=110, 3rd group, n=80 and 4th quartile group,n=76. The blood levels of total bilirubin (TBIL), total cholesterol (TC), LDL-C, HDL-C, TG and ifbrinogen were measured and bilirubin blood lipid comprehensive index, TC/(HDL-C+TBIL) and LDL-C/(HDL-C+TBIL) were calculated respectively.
Results:①By CAG examination, compared with Non-CAD group, CAD group had increased TC, LDL-C, ratios of TC/(HDL-C+TBIL), LDL-C/(HDL-C+TBIL) and FIB,P<0.05; decreased TBIL and indirect bilirubin (IBIL),P<0.05.②By Gensini scoring system, the level of TBIL, IBIL, ratios of LDL-C/(HDL-C+TBIL), TC/(HDL-C+TBIL), HDL-C and FIB were different among 4 groups,P<0.05.③ Logistic regression analysis indicated that with excluded interactional factors, the bilirubin blood lipid comprehensive index was the independent risk factor for CAD[TC/(HDL-C+TBIL): OR: 1.668, 95% CI:1.065~2.784,P=0.028; LDL-C/(HDL-C+TBIL ): OR: 1.786, 95% CI: 1.021~2.879,P=0.030].④Correlation analysis presented that TC/(HDL-C+TBIL), LDL-C/(HDL-C+TBIL) and FIB were positively related to Gensini scoring system (r=0.423,P<0.01), (r=0.417,P<0.01) and (r= 0.293,P <0.01) respectively.
Conclusion: Bilirubin blood lipid comprehensive index and ifbrinogen were positively related to severity of coronary lesions in CAD patients.

Objective To define the indications and evaluate the results of various surgical treatment options in patients with nonparasitic hepatic cysts. Methods The clinical data of 284 patients with nonparasitic hepatic cysts treated in our hospital from January 1995 to December 2005 were retrospectively analyzed. Results Percutaneous aspiration and sclerotherapy were performed in 161 cases and complications occurred in 9 (5.59%), recurrence in 53 (32.92%) and the mortality was 0%.Open surgery was conducted in 71 cases and the complications occurred in 16 (22.54%), recurrence in 8 cases (11.27%) and the mortality was 2.82%. Laparoscopic surgery was employed in 52 cases and complications occurred in 7 ( 13.46%), recurrence in 6 (11.54%) and the mortality was 1.92%.Conclusion There is currently no general agreement in the literature concerning when nonparasitic hepatic cysts should be treated. Laparoscopic surgery was more favorable than other therapeutic options.However, we should choose individually suitable methods according to different clinical symptom of patients.

Objective To establish an expression system of TCRγ9/δ2-Fc protein by baculovirus vector ex-pression system and identify biological function of expressed TCRγ9/δ2-Fc protein. Methods γ9Fc and 82 (OT3) Fc gene fragments were amplified by overlap PCR and inserted into expression vector pBACp10ph. The recombinant plasmid pBACp10ph-γ9/δ2(OT3)-Fc and the baculovirus DNA were co-transfected into st9 cells. The expression position of TCRγ9/δ2 (OT3)-Fc was identified by Western blot and the expression efficiency of γ9Fc and δ2 (OT3) Fc was tested by flow cytometry (FCM). Furthermore, the binding activity of TCRγ9/δ2 (OT3)-Fc protein with SKOV3 ceils and MNS protein was evaluated with laser scanning confocal microslopy and surface plasmon resonance (SPR). Results The recombinant vector pBACp10ph-γ9/δ2(OT3)-Fc was constructed and TCRγ9/δ2(OT3)-Fc protein was expressed in sf9 ceils. However, the expression efficiency of γ9Fc and 82 (0T3) Fc was quite differ-ent. It was proved that purified TCRγ9/δ2 (OT3)-Fc protein can bind with SKOV3 cell and MNS protein. Conclu-sion TCRγ9/δ2-Fc protein is successfully expressed in baculovirus vector expression system and TCRγ9/δ2-Fc protein can simulate the binding activity of TCR in vitro.

T_4 was coupled to human serum albumin(HSA)to make the conjugate T_4-HSA,a polyvalent T_4 analogue rather than monovalent T_4 per se alone.A new strategy for sandwich enzyme immunoassay model system of small molecular hapten hormones FT_4 was developed,such as intra-assay CV,inter-assay CV,average recovery, normal and abnormal values were fit for clinical application.The sensitivity was as much as 10 times higher than conventional competitive enzyme immunoassay.

Objective To explore the protective effect and mechanism of astaxanthin (AST) on the acute kidney injury induced by iohexol in rats.Method Thirty rats were randomly divided into five groups:control group (Ctrl);iohexol group (CM);astaxanthin group (AST,100 mg/kg),low astaxanthin dose group (LAST+CM,50 mg/kg) and high astaxanthin dose group (HAST+CM,100 mg/kg),6 in each group.The rats in AST,LAST+CM,HAST+CM groups were administrated with AST by oral gavages using an intubation needle for 10 consecutive days.The rats in Ctrl and CM groups rats in Ctrl,CM groups were given with dissolvant instead in equal volume.Except for the Ctrl and AST groups,on day 8,rats were given indomethacin,L-NAME and iohexol in their femoral vein under chloral hydrate anesthesia to build a contrast induced-nephropathy (CIN) model.At the end of the experiment (72 h after CIN induction),all rats were sacrificed.The Scr level,BUN level,renal histology,renal tissue activities in superoxide dismutase (SOD),catalase (CAT),glutathione peroxidase (GPx),Glutathione (GSH) and level of malondialdehyde (MDA) were performed.Apoptosis of renal cells was detected by Bcl-2,Bax and Caspase-3 p17 with Western blot.Results Compared with Ctrl group,the levels of Scr,BUN were significantly increased in CM group (all P ＜ 0.01);while compared with CM group,the indicators were decreased in treatment groups (P ＜ 0.01).Renal tubular structure damage,medulla congestion,loss of brush border,vacuolar degeneration,apoptosis and proteinaceous casts were observed in the CM group,and the renal injury scores were higher compared with Ctrl group (P ＜ 0.05),however,administrated with AST could significantly improve the changes (P ＜ 0.05).Oxidative stress indicators showed that MDA level were increased while SOD,GPx,GSH activities were significantly decreased at CM group (all P ＜ 0.05),and the indicators above were ameliorated in treatment groups (all P ＜ 0.05).Western blot showed that the expression of Bcl-2 was down-regulated while the Bax,Caspase 3 p17 was up-regulated respectively at CM group (P ＜ 0.05),while the HAST+CM group could prevent the changes.Conclusions Iohexol can results in oxidative stress increased in kidney,which activate Caspase-3 p17 signal path,down-regulated Bcl-2 expression,up-regulated Bax expression respectively,and lead to cell apoptosis.AST can ameliorate the changes,especially with high AST dose,which suggest that the possible protection mechanism is by ameliorating oxidative stress and inhibiting apoptosis pathways.

Objective To explore the relationship between serum tumor markers and cervical cancer by using Logistic regression, and to further establish the diagnosis model of squamous cell carcinoma antigen (SCC) in cervical cancer by using chi-squared automatic interaction detector (CHAID) analysis of decision tree.Methods Total of 581 cases of cervical cancer,342 cases of cervical benign diseases and 341 cases of healthy controls who detected tumor markers in Taizhou Hospital of Zhejiang during 2010-2013, were retrospectively studied.The test results of carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), SCC, and alpha fetoprotein (AFP) were reviewed.The Logistic regression were firstly used in screening the related tumor markers of cervical cancer, and then the CHAID method of decision tree was used in determining the values of the related tumor markers on the diagnosis of cervical cancer.The SCC elevated cases of uterine disease from January 2014 to December 2014 were collected to verify the diagnostic value of SCC in cervical cancer patients.Results Logistic regression analysis showed that among the 5 tumor markers which might be associated with cervical cancer, SCC was the only one which had statistical significance between cervical cancer and cervical benign diseases (Wald x2 =22.120,P =0.000), the OR and its 95％ CI was 1.900 (1.454-2.483).With the SCC numerical increases, the proportion of patients with cervical cancer also gradually increased, when SCC ＞ 2.20 μg/L, the positive predictive value was 94.7％.In 284 cases of SCC higher than 2.20 μg/L who considered as uterus related diseases, there were 270 cases (95.1％) who were eventually confirmed as cervical cancer.Conclusion There was a good diagnostic value of SCC for cervical cancer patients.
