Abstract: TGF-β/Smad signaling pathway has a wide range of biological activities and plays an important roles in regulating cell growth, adhesion, differentiation, cell dynamic balance, and immune responses. The higher activity of TGF-β/Smad signaling pathway may promote scar formation, organ fibrosis, immunosuppression, and late-stage cancer progression, while low activity may lead to inflammation, dysplasia, poor healing and oncogenesis. The function of the TGF-β/Smad signaling pathway is extremely complex and can exhibit inhibitory or enhancing effects on immunity and inflammation under different circumstances, but immunosuppressive and anti-inflammatory effects are dominant. During HIV infection, the TGF-β/Smad signaling pathway interacts with HIV in a complex manner as HIV proteins tat and gp120 can induce TGF-β expression. Meanwhile, this signaling pathway may also play a role in HIV infection and replication, latent virus reservoir, host immune deficiency and HIV-related inflammation. It is worth noting that even though TGF-β, which mainly exhibits anti-inflammatory effects, is induced by HIV, high levels of TGF-β do not seem to inhibit HIV-related inflammation. So far, the relationship between TGF-β/Smad signaling pathway and HIV infection has not been elucidated, and its role and mechanism in HIV infection and related illnesses need further exploration and validation. This review summarizes the relevant research progress on the TGF-β/Smad signaling pathway and HIV infection, and provides a reference for further understanding of HIV pathogenesis and exploring strategies of AIDS treatment.

Objective To observe the effects of dexmedetomidine on inflammatory responses and insulin resistance during cardiac operations with cardiopulmonary bypass(CPB).Methods Fifty patients scheduled for elective cardiac valve replacement with CPB were equally and randomly divided into two groups using a random number table:observation group and control group(n =25).A loading dose of dexmedetomidine 1.0 μg/kg was injected intravenously over 1 5 min after induction,followed by continuous infusion at 0.4 μg·kg-1 ·h-1 until the end of CPB in doservation group.While the e-qual volume of normal saline was given in control group.After induction(T1 ),at 30 min after the be-ginning of CPB(T2 ),at the end of CPB(T3 ),and at 2 h after the end of CPB(T4 ),the jugular venous blood samples were taken for determination of serum concentrations of TNF-a,IL-6,insulin and blood glucose.The insulin sensitivity index (ISI ) = 1/(glucose × insulin )was obtained. Results Compared with control group,the serum TNF-a and IL-6 concentrations at T2-T4 were sig-nificantly decreased in observation group(P <0.05),the serum insulin and blood glucose concentra-tions at T2 ,T3 were significantly decreased in observation group(P <0.05 ),the ISI at T2 ,T3 were significantly increased in observation group(P <0.05).Conclusion Dexmedetomidine can reduce in-flammatory responses,thus reducing insulin resistance and blood glucose during cardiac operations with CPB.

OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

BACKGROUND:Previous studies have found that cyclic tensile stress can induce the proliferation of human periodontal ligament fibroblasts in a certain time. OBJECTIVE: To observe the effect of cyclic tensile stress on the expression of connective tissue growth factor in human periodontal ligament fibroblasts, and to clarify the role of JNK, p38MAPK, PI3K pathway in the cyclic tensile stress-induced expression of connective tissue growth factor in human periodontal ligament fibroblasts. METHODS:Human periodontal ligament fibroblasts culturedin vitro were given stimulation of cyclic tensile stress in vitro for 1, 6, 12, 24 hours using multi-channel cel stretch stress loading system (experimental group). Control group was set up and not given any stimulation at the same time. The cels under stress application for 12 hours were given specific inhibitors of JNK, p38MAPK, PI3K respectively at the beginning, and were compared with those with no inhibitors. The concentrations of connective tissue growth factor in the culture supernatant were measured by ELISA. The mRNA expression of connective tissue growth factor in human periodontal ligament fibroblasts was detected by real-time RT-PCR. RESULTS AND CONCLUSION:Compared with the control group, the expression of connective tissue growthfactor in human periodontal ligament fibroblasts under cyclic tensile stress began to increase at 1 hour, increased manifestly at 6 hours, reached the peak at 12 hours, and then decreased at 24 hours. The expression of connective tissue growth factor was reduced by the specific inhibitors of JNK, while the specific inhibitors of p38 MAPK, PI3K had not the same effect. In a certain time, the cyclic tensile stress can induce a time-dependent increase in mRNA and protein levels of connective tissue growth factor. Along with the extending of time, the expression of connective tissue growth factor begins to decrease. Cyclic tensile stress can regulate expression of connective tissue growth factor in human periodontal ligament fibroblasts via the JNK pathway.

[Objective]Electrophoretic analysis of rat chemically extracted acellular nerve allograft(CEAN) protein was performed to investigate the protein of CEAN.Dorsal root ganglia of chicken were cultured onto the surface of CEAN slice to observe the effect of CEAN structure on the fiber regeneration.[Method]The CEAN were perpared according to Sondell method and electrophoresed to observed whether the electrophoresis strip of 28-30kDa(Myelin Protein) exited or not.Dorsal root ganglia of chicken were cultured onto thc surface of CEAN slice and dyed with nerve fiber fluorescence to observe the orientation of nerve fiber growth on the surface of CEAN slice.[Result]Electrophoretic analysis of rat CEAN protein showed that the electrophoresis strip of 28-30 kDa totally disappeared.A large number of nerve fibers grew from DRG along the basement membrane of CEAN.[Conclusion]No myelin protein remained in the CEAN,while the basement membrane structure of CEAN can induce the nerve fiber to grow.

[Objective] To investigate the biological characteristics of Wharton’[KG-38x]s jelly-derived mesenchymal stem cells (WJMSCs) and their differentiation into Schwann cell-like cells, and to provide a new cell seed source for nerve tissue engineering or cell therapy. [Methods]Umbilical arteries, veins and umbilical cord tunica externa were removed , and the remaining tissue (Wharton’[KG-38x]s jelly) was harvested.The umbilical cord was cut into small fragments and cultured with DMEM in orderto gather. Cultured WJMSCs were confirmed by the detection of MSC-specific cell-surface markers. WJMSCs were differentiated along a glial cell lineage using an established cocktail of growth factors. Immunocytochemical staining and Western blot were used to evaluate the characteristics of differentiated WJMSCs.[Results]WJMSCs were immunonegative for the haemopoietic cell-surface markers (CD34 and CD45) and neural stem cell marker (nestin), and immunopositive for MSC surface markers CD44, CD105, Stro-1 and vimentin. WJMSCs treated with a mixture of glial growth factors adopted a spindle-like morphology similar to Schwann cells. Immunocytochemical staining and Western blot analysis revealed that the treated cells expressed the glial markers p75 and glial fibrillary acidic protein indicative of differentiation.[Conclusion]WJMSCs can be differentiated into the cells that are Schwann-like in terms of morphologic features and phenotype and may be suitable as Schwann-cell substitutes for nerve repair in clinical application.

and each of the resistant strains was resistant at least to 5 antibiotics.13 strains out of the 28 harbored plasmids ranging from 1 to 6 in number and 105 Md to 2.7 Md in molecular weight.The plasmid with 50 Md was the most popular one in this study,which may be the epidemic plasmid in the urologic unit.It was also found that 2 different species of bacteria isloated from the patients with infection of the urinary tract showed identical plasmid profile,which indicates that these 2 patients may be associated with each other.
