Objective To study the predictive value of high-sensitivity C-reactive protein (hs-CRP) to perineonate mortality in early onset severe pre-eclampsia (EOSPE) pregnant women. Methods Seventy-five pregnant women with EOSPE (EOSPE group) and 75 pregnant women with gestational hypertension (control group) were selected. The serum tumor necrosis factor (TNF)-α, interleukin (IL)-2 and hs-CRP levels were detected. The data of perineonate death in EOSPE group were recorded, then the pregnant women were divided into death subgroup and survival subgroup. Results The hs-CRP, TNF-αand IL-2 levels in EOSPE group were significantly higher than those in control group:(7.2 ± 2.1) mg/L vs. (2.5 ± 1.0) mg/L, (28.9 ± 5.3) ng/L vs. (12.4 ± 3.5) ng/L and (134.3 ± 34.6) ng/L vs. (104.2 ± 28.5) ng/L, and there were statistical differences (P<0.05). In EOSPE group, 18 perineonates died (death subgroup), and 57 perineonates were survival (survival subgroup). The hs-CRP in death subgroup was significantly higher than that in survival subgroup: (8.9 ± 1.3) mg/L vs. (7.1 ± 1.2) mg/L, and there was statistical difference (P<0.05). But there were no statistical differences in TNF-αand IL-2 between death subgroup and survival subgroup (P>0.05). Receiver operating characteristic curve analysis result showed that the best threshold of hs-CRP for predicting the perineonate mortality caused by EOSPE was 7.98 mg/L, and the area under the curve was 0.779 (95％CI 0.637 to 0.922), with a sensitivity of 0.83 and a specificity of 0.68. Conclusions Inflammatory reaction is involved in the pathophysiological process of EOSPE, and hs-CRP is a good index to predict perineonate death in EOSPE pregnant women.

The aim of this study was to figure out the predictors of early postoperative catheter-related bladder discomfort (CRBD) after urological surgery. We designed a prospective observational study in our hospital. Consecutive adult patients undergoing surgery under general anaesthesia or epidural anaesthesia necessitating urinary catheterization were included during a 3-month period. severity of bladder discomfort was assessed on a 4-point scale: (1) no pain, (2) mild pain (revealed only by interviewing the patient), (3) moderate (a spontaneous complaint by the patient of a burning sensation in the urethra and/or an urge to urinate and/or sensation of urethral foreign body without any emotional agitation) and (4) severe discomfort (agitation, loud complaints and attempt to remove the bladder catheter associated with a burning sensation in the urethra). Predictors of CRBD were identified by univariate and multivariate analysis. Totally, 116 patients were included, of which 84.5% had CRBD (mild CRBD: 40.5%; moderate or severe CRBD: 44.0%) at day 1, while 31.9% developed CRBD (mild CRBD: 29.3%; moderate or severe CRBD: 2.6%) at day 3. We evaluated 9 potential forecast factors of CRBD, and univariate Chi-square test showed male gender [OR=2.4, 95%CI (1.1-5.6), P<0.05], abdominal open surgery compared with transurethral surgery [OR=0.3, 95%CI (0.1-0.6), P<0.05], abdominal surgery compared with laparoscopic surgery [OR=3.3, 95%CI (1.2-8.9), P<0.05] and history of catheterization [OR=0.5, 95%CI (0.2-0.9), P<0.05] were independent predictors of moderate or severe CRBD in the patients after surgery. While multivariate logistic regression analysis showed that the abdominal open surgery [EXP(B)=3.074, 95%CI (1.3-7.4), P<0.05] and the history of catheterization [EXP(B)=2.458, 95%CI (1.1-5.9), P<0.05] might contribute more to the occurrence of moderate or severe CRBD. In conclusion, this observational study identified that the type of surgery and the history of catheterization might be predictive factors of moderate and severe CRBD after urological surgery.

Objective To establish a simple , practical , highly-effective and stable method for the isolation and cultivation of rat hair follicle cells. Methods Under sterile condition, single hair follicle was taken out after the skin around the barbel of SD neonatal rats was sheared off. And then the hair follicles were digested with two-step method with Type Ⅰcollagenase and trypsin. The obtained cell suspension was planted into the culture plate which was covered with extracellular matrix, and then was cultivated with K-SFM culture medium containing fetal bovine serum with volume fraction of 1%. On the next day, K-SFM culture medium was replaced with serum-free culture medium. The remaining tissues were cut into pieces and spread out in the culture flask, and then were cultivated with HG-DMEM culture medium containing serum. Two kinds of cells were harvested and then were identified by immunofluorescence. The hair follicle epithelial cells were tested by flow cytometer. Results The hair follicle epithelial cells obtained through the above methods showed rapid adherence, and were round or polygon-like , with typical cobblestone-like morphology. The long spindle-shaped cells were seen around the tissues cultivated, having many protrusions on the surface of the cells, and they were interconnected into reticular structure. The expression of cytokeratin 15, cytokeratin 19 and β1 integrin in epithelial cells were positive. Most of the epithelial cells were in the G1 phase, accounting for 75.6%. The expression of laminin ( LN), fibronectin ( FN) and vimentin in the connective tissue sheath cells were also positive. Conclusion The cells harvested by modified two-step enzyme digestion method have confirmed as hair follicle cells and fibroblasts, and the obtained cells are of rapid adherence, good homogeneity, and active proliferation.

Objective To explore the feasibility of repairing skin defect with Pelnac tissue engineering skin and cultured epidermal stem cells ( ESCs) and fibroblasts. Methods ESCs and fibroblasts in SD rats were isolated and cultured in vitro, and then were detected by immunohistochemistry. Fibroblasts were seeded in Pelnac material to construct dermis, and ESCs were seeded on the surface of dermis to construct tissue engineering skin. Thirty BALC/c nude mice were randomly divided into groups A, B and C. After mouse back skin defect model was established, group A was transplanted with Pelnac material, group B was transplanted with compound of Pelnac and fibroblasts, and group C was transplanted with Pelnac tissue engineering skin. The wound healing was observed after operation. The wound tissues were sampled for pathological histology test on the 5th and 7th day after transplantation. Results The expression of cytokeratin 15 and β1 integrin in ESCs was positive, and the expression of laminin ( LN) and fibronectin ( FN) in fibroblasts was positive. In group C, the wound healing of nude mice was the best, characterized by the proliferation of fibroblasts, obvious new capillaries and regularly arranged epidermal cells at the transplantation sites. Conclusion Pelnac tissue engineering skin has good effects on promoting repair of skin defect of nude mice.

Methods A total of 80 patients with early diabetic nephropahy were randomly divided into two groups.The patients in control group(n=40)received valsartan at a dose of 80rag/day ,while in treated group(n=40)on the base of the same treatment as control group, added simvastatin 20 mg/everyrfight. To compare the differences of lipids,urine albumin excretion rate(UAER) and C-reactive protein(CRP) before or after treatments through 12 weeks. Re-sults The UAER of two groups decreased obviously after therapy,especially the treated group(P<0.01) ;the lipids and CRP also decreased evidently in the treated group (P<0.05). Conclusion The lipids, UAER, CRP of patients in early diabetic nephropathy could be down-regulated,with combined medication of the simvastatin and valsartan, and the injury of renal alleviated.

Objective:To evaluate the efficacy and safety of continuous intrathecal morphine infusion system for patients with refracto-ry cancer pain. Methods:Seventeen patients with refractory cancer pain were implanted with intrathecal catheters and connected with a continuous external electronic patient-controlled analgesia (PCA) pump for intrathecal morphine analgesia. Visual analogue scales (VAS) score, the dose of routine opioids, and the score for quality of life before and after intrathecal analgesia were recorded. Adverse reactions were observed. Results:After the application of continuous intrathecal morphine analgesia, the VAS score of pain was 2.9±1.8, which is lower than 7.2±2.5 before intrathecal analgesia (P<0.001). Moreover, the dose of routine opioids (i.e., equianal-gesic dose of morphine) was 42.1 ± 7.5 mg/day, which is significantly lower than 282.9 ± 95.5 mg/day before intrathecal analgesia (P=0.004). The scores of general activity, mood, and sleep after intrathecal analgesia were significantly lower than those before intrathe-cal analgesia (P<0.05). However, the analgesic satisfaction of patients considerably increased after intrathecal analgesia (P<0.001). Ad-verse reactions included withdrawal syndrome, headache, urinary retention, and intrathecal infection. Conclusion:The continuous in-trathecal morphine infusion with PCA is effective and safe on analgesic treatment for patients with refractory cancer pain.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.
