Objective To investigate the effects of mesenchymal stem cells (MSCs) transplantation combining with vascular endothelial growth factor (VEGF) gene therapy on myocardium rebuilding,angiogene- sis,and heart function improvement in rats with myocardial infarction.Methods SD rat MSCs were isola- ted,cultured in vitro,labeled with BrdU and transfected by Ad.VEGF gene.Four weeks after left anterior descending artery was ligated to created rat myocardial infarction,cardiac function was examined with echocar- diography,rats were randomly divided into four groups (n=10 in each group):GroupⅠ:MSCs/Ad.VEGF implantation;GroupⅡ:MSCs implantation;GroupⅢ:Ad.VEGF injection;GroupⅣ:Control.MSCs dif- ferentiation was observed 4 weeks after transplantation.Immunohistochemistry and angiogenesis were observed. Echocardiography was performed to detect the effects on heart function.Results MSCs labeled with BrdU could be identified in host hearts in groupⅠandⅡ,most of them positively stained with cTnT antibody. Echocardiography indicated that the improvement of the LVEF value in groupⅠwas more significant than that in the other three groups (P＜0.01,respectively).Some cells were incorporated into the coronary capillaries in the infarcted region.The capillary density in groupⅠwas higher than that in the other three groups (P＜0.01,respectively).Conclusion MSCs implantation combining with VEGF gene therapy can obviously re- pair damaged myocardium and enhance the angiogenesis in ischemic heart tissue.

Objective To observe the steps of vascular smooth muscle cells (VSMCs) calcification induced by high phosphate enviroment in vitro. Methods VSMCs were incubated with high phosphate (2.5 mmol/L or 3.5 mmool/L) medium for different times. Expression of core binding factor α1(Cbfα1), osteopontin(OP), collagen type Ⅰ(Col Ⅰ), osteocalcin(OC) and α-smooth muscle actin (α-SMA) was investigated by Western blot, immunofluorcscencc staining and real time PCR. Mineral deposition was assessed by von Kossa aad Alizarin red staining. Ultrastructure of VSMCs calcification was observed by electron microscopy (EM). Results Up-regulated expression of osteoblast-specific transcription factor Cbfα1 in the nuclei oceured at as early as 12 hours. The protein of Col Ⅰ and OP was up-regalated when VSMCs were incubated in high phosphate medium for 3 days, and content of OC increased at the time of 6 days. When cultured in 2.5 mmol/L phosphate medium for 15 days, VSMCs lost their lineage marker α-SMA, developed granular calcium deposits. Moreover, the results of real time PCR indicated mRNA level of OP and Col Ⅰ increased at day 1, OC increased at day 5 and α-SMA level decreased at day 10, respectively. Ultrastructural analysis also confirmed the presence of collagen and matrix vesicles in the cells. Conclusion VSMCs phenotype transformation induced by high phosphate enviroment is an orchestrated, highly regulated process.

Human beta defensin 2 (HBD-2) may play an important role in human defense against infection. Its antimicrobial capacity has been fully documented in in vitro study. In order to evaluae its in vivo effects, we developed an HBD-2 transgenic mouse model. The HBD-2 minigene containing CMV promoter, full length of HBD-2 cDNA and BGH polyA tail was generated by PCR amplification and introduced into the fertilized oocytes of C57 X ICR hybridized mouse by microinjection, and offspring were produced. DNA was isolated from the tails of the mouse pups, and the HBD-2 minigene incorporation was analyzed by PCR using HBD-2 specific primers. The HBD-2 gene expression in the multi-tissues of transgenic mice was determined at mRNA level by RT-PCR and at peptide level by immunohistological staining with the use of HBD-2 monoclonal antibody. The results showed that among 17 F0 transgenic mice, HBD-2 positive signal was determined by PCR in 4 mice, suggesting that HBD-2 minigene has been incorporated into the offspring mice. Meanwhile, a widespread expression of HBD-2 mRNA and peptide was detected in the F1 transgenic mice's multi-tissues such as trachea, lung, intestine, esophagus, testis, spleen, skin, endothelium and brain.

AIMAnnonaceous acetogenin 89-2 was obtained from atemoya plant. To investigate the effect of 89-2 on experimental chemotherapy against xenografts derived from multidrug resistant KBv200 cells and parental drug-sensitive KB cells.

METHODSCytotoxicity was determined by tetrazolium (MTT) assay. The models of KB and KBv200 xenografts in nude mice were established to investigate the effect of 89-2 on experimental chemotherapy against cancer in vivo. Mechanistic experiments were conducted to examine the function of P-gp by Fura 2-AM assay.

RESULTSThe compound 89-2 showed potent cytotoxicity in KBv200 and KB cells, and the mean IC50 of 89-2 to KBv200 and KB cells was 48.7 and 64.6 nmol.L-1, respectively. The IC50 of 89-2 to multidrug resistant (MDR) cells was similar to that to the parental drug-sensitive cells (P < 0.05). In the models of KBv200 and KB cell xenografts in nude mice, 89-2 (0.90 mg.kg-1, q2d x 6) exhibited 52.3% and 56.5% in inhibiting the growth of xenografts, respectively. The toxicity was endurable. The intracellular accumulation of Fura-2 in KBv200 cells increased to 1.66, 2.03, and 2.74-fold, respectively, by addition of 12.8, 64 and 320 nmol.L-1 of 89-2.

CONCLUSIONBoth MDR KBv200 cells and parental drug-sensitive KB cells were sensitive to the treatment of 89-2 in vitro and in vivo. The mechanism of overcoming MDR was associated with the decrease of P-gp function MDR cells.

Objective To investigate the effects of Yiqi Huoxue Xiaozheng Formula on cell apoptosis in rats with benign prostatic hyperplasia (BPH); To preliminarily explore its mechanism of action. Methods Totally sixty 8-week-old male SD rats were randomly devided into normal group, positive control group, Yiqi Huoxue XiaozhengFormula low-, medium-, and high-dose groups, with 10 rats in each group. Except for the rats in normal group, rats in other groups were treated with castrate and testosterone propionate injection to replicate BPH model. The normal group and the model group were given normal saline for gavage; Yiqi Huoxue Xiaozheng Formula low-, middle-, and high-dose groups were given Yiqi Huoxue Xiaozheng Formula 10, 20, 40 mg/100 g for gavage, respectively; rats in positive control group were given Longkai Granule suspension 11 mg/100 g for gavage, once a day, for 30 d. Twenty-four hours after the last administration, the rats were sacrificed by cervical dislocation. The prostate tissue was taken. The protein expressions of Bcl-2 and Bax in the prostate tissue were detected by immunohistochemistry. Results Compared with the normol group, the expression of Bax in the prostate tissue of the model group decreased significantly, while the expression of Bcl-2 increased significantly; Compared with the model group, the expression of Bax in the prostate tissue of rats in administration groups increased significantly, while the expression of Bcl-2 was significantly reduced, and Yiqi Huoxue Xiaozheng Formula high-dose group was superior to other groups. Conclusion Yiqi Huoxue Xiaozheng Formula can improve benign prostatic hyperplasia by promoting the apoptosis of rat prostate tissue, and its mechanism is related to the increase of the expression of Bax protein and the decrease of Bcl-2 protein expression in prostate tissue.

Postpartum visits (PPVs) are still underutilized in rural China, and identification of factors that influence PPV use is important in ensuring the utilization of maternal health services and for wellbeing of women. A cross-section study was undertaken to collect related data from 347 rural women interviewed six weeks or more after delivery, and an ANOVA was performed to find whether there were significant differences in the number of PPVs among different rural areas in China. According to Andersen's socio-behavioral model of health service use, factors were divided into equitable and inequitable ones. Chi-squared test, univariate and multiple analyses were used to determine the equity of PPV use by identifying factors that were most strongly associated with the use of a PPV. The results showed that 20.2% of the respondents (n=70) did not receive any PPVs, and 62.5% (n=173) of those who had PPVs (n=277) did not receive standard PPVs (referring to at least 3 visits). There was no significant difference among different rural areas in terms of the number of PPVs (F=1.514, P=0.211). Multiple regression analyses revealed that enabling factors such as compensation for delivery expense [OR (95% CI)=2.825 (1.331, 5.995)], village type [OR (95% CI)=1.802 (1.021, 3.182)] and service quality [OR (95% CI)=1.847 (1.074, 3.176)] were strongly associated with PPV use. Both enabling factors such as home visits [OR (95% CI)=1.855 (1.085, 3.174)], service quality [OR (95% CI)=1.993 (1.155, 3.439)] and need factors such as low birth weight [OR (95% CI)=4.424 (1.482, 13.203)] were significantly associated with standard PPV use. Our results suggested that the equitable access to PPVs has been considerably improved in rural areas in China. The associations between inequitable factors and PPV use warrant further exploration, and policies aimed at improving quality and patterns of service supply are needed in order to ensure a full equitable access to maternal health services.

OBJECTIVETo evaluate clinical efficacy of holmium laser enucleation of the prostate in the treatment of benign prostatic hyperplasia (BPH) and overactive bladder (OAB).

METHODSFrom May 2007 to May 2010, a total of 37 patients diagnosed BPH and OAB were treated by holmium laser enucleation of the prostate. After a mean follow-up of 4.9 months postoperatively, indices such as International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), residual urine volume and video urodynamics were monitored and statistically analyzed.

RESULTSThe mean preoperative IPSS and QOL score were 29.6 ± 5.2 and 4.3 ± 0.9, and decreased to 4.6 ± 1.2 and 1.2 ± 1.0 postoperative. The mean Qmax was (6 ± 3) ml/s preoperative and increased to (21 ± 5) ml/s postoperative. Preoperative average residual urine volume was (167 ± 11) ml, decreased to (41 ± 18) ml after operation. During follow-up, 86.5% patients' symptoms and quality of life improved continuously, however 13.5% patients existed residual postoperative OAB symptoms.

CONCLUSIONSWhen BPH with OAB patients exist bladder outlet obstruction, bladder outlet obstruction should be relieved first then OAB symptoms can be relieved in majority of patients, but some patients have residual symptoms.

Objective:To investigate the clinical effect of flow-through anterolateral thigh perforator flap with fascia lata for repairing dorsal wounds of the hand and foot with extensor tendon defects.Methods:A retrospective case series study was conducted to analyze the clinical date of 14 patients with hand and foot wounds associated with extensor tendon defects admitted to Ruihua Affiliated Hospital of Soochow University from January 2015 to December 2019. There were 13 males and 1 female，aged 10-57 years［（39.2±13.4）years］. The wounds were all single with the area of 10 cm×4 cm to 23 cm×12 cm，including 8 wounds on the back of the hand and 6 wounds on the back of the foot. There was 1 patient accompanied with 1 tendon defect，10 with 4 tendon defects and 3 with 5 tendon defects，with the length of tendon defects ranging from 2.0 to 6.0 cm［（3.8±1.4）cm］. The dimension of flaps ranged from 12 cm×5 cm to 23 cm×13 cm，with the fascia lata from 11 cm×5 cm to 20 cm×7 cm. The deficient extensor tendons were repaired with the fascia lata and vascular pedicles were anastomosed by flow-though. A bilobed flap was harvested in 3 patients and a single flap in 11 patients. Donor sites were sutured directly. The survival of the flap and healing of the donor area were detected after operation. The extremity revascularization and shape and sensation recovery of the flap were measured at the last follow-up. The upper extremity functional evaluation standard set up by Hand Surgery Society of the Chinese Medical Association and Maryland foot functional score were used to evaluate the hand and foot function before operation and at the cast follow-up，respectively. The donor site complications and performance of tendon release or flap thinning in the second stage were recorded.Results:All patients were followed up for 8-30 months［（15.3±6.2）months］. All flaps survived successfully，with wounds and thigh donor areas healed by first intension. No significant effect of revascularization was observed on recipient sites，and acceptable cosmetic outcomes and sensation recovery of the flap were achieved at the final follow-up. For patients with dorsal wounds of the hand，the extensor function recovered in different degrees，and the flexion activities of the fingers were not limited. The total active movement was 180°-250°［（226.3±21.7）°］at the last follow-up，compared to preoperative 110°-170°［（145.6±13.2）°］（ P<0.01）. According to the upper extremity functional evaluation standard，the function was excellent in 4 patients，good in 2 and fair in 2. For patients with wounds of the foot，the flexion and extension function was good，with no obvious deformity of toes，and the Maryland foot functional score ranged from 60 to 92 points［（76.0±12.7）points］at the last follow-up，significantly improved from preoperative 18-45 points［（27.4±7.8）points］（ P<0.01），including excellent results in 2 patients，good in 3 and fair in 1. Only linear scars were left in the thigh donor area，and there was no discomfort such as scar contracture or pain. Four patients underwent skin flap thinning at 4-8 months after operation and none underwent a tenolysis. Conclusion:Repair of dorsal wounds with extensor tendon defects of the hand and foot by flow-through anterolateral thigh perforator flap with fascia lata can reduce interference to recipient sites and repair wounds and extensor tendons simultaneously，which can obtain good flexion and extension function and minor damage to the donor area.
