With the combined applications of steam distillation, water extraction and alcohol precipitation, liquid-liquid extraction and column chromatography over macroporous resin, a splitted-fractions method of the chemical constituents of Poria cocos was established. The unoverlapping property of the fractions of P. cocos was qualitatively analysed by using principal component analysis and cluster analysis. With angle cosine, squared euclidean distance and the overlapping analysis of peak area of crude herbs, the unoverlapping property of the fractions of P. cocos was half-quantitatively analysed. The chemical components of P. cocos was divided into the fractions of polysaccharide, petroleum ether, ethyl acetate, alcohol eluate from macroporous resin and water eluate from macroporous resin. Non similarity degree among each chemical fraction was above 80% and main chemical components were identified. The established method for splitting fractions of P. cocos has good stability and repeatability and all chemical components in P. cocos could be completely divided into six fractions. It is the first time that the author half-quantitatively analyse the unoverlapping property of the chemical fractions of P. cocos.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

OBJECTIVETo explore the technique and clinical results of close reduction by manipulation and minimally invasive percutaneous osteosynthesis with intramedullary nail for the treatment of femur shaft fractures. methods: A retrospective study was conducted to analyze 96 patients with the femur shaft fractures who had been treated with close reduction by manipulation and minimally invasive percutaneous osteosynthesis with intramedullary nail. There were 67 males and 29 females. The average age of patients was 39 years old (ranging from 16 to 88). According to AO fracture classification for the femur shaft fractures,there were 29 cases of type A,46 type B,21 type C.

RESULTSAll the patients were followed up and the duration ranged from 12 to 24 months (averaged, 15 months). All the fractures showed union. The time required for the bony union ranged from 3 to 10 months (averaged,4 months). The clinical results were evaluated by Thorsen classification system. At the latest follow-up, 87 patients obtained excellent results, 7 good, 2 fair.

CONCLUSIONThis treatment method combines advantages of intramedullary nail with close manipulative reduction, so can get satisfactory clinical results for the treatment of femoral shaft fracture with minimal trauma.

OBJECTIVETo discuss the mechanism of scar hypertrophy in adenosine receptor A(2A) (A(2A) R) knockout mice.

METHODSAnimal models of hypertrophic scar were established in 12 A(2A) R knockout mice and 12 wild-type mice as control. The thickness and the size of transverse section of the hypertrophic scar were observed by H-E staining. The hydroxyproline (HYP) in the scar was measured colorimetrically. The TGF-beta expression was tested by Western blotting method.

RESULTSThe hypertrophic scar in wild-type mice was more severe than that in knockout mice. Compared with self-control, the increase of the thickness and the size of transverse section of hypertrophic scar was markedly higher in wild-type group than in the knockout group (P < 0.01). There was significant difference in HYP content between the two groups (P < 0.01). Compared with self-control, the increase of TGF-beta expression in wild-type group was much more than that in knockout group (P < 0.01).

CONCLUSIONSThe TGF-beta expression decreases in the A(2A) R knockout mice. The scar hypertrophy is also much less in the A(2A) R knockout mice.

OBJECTIVEDamage control surgery (DCS) deals with the complex surgical problems by stages. This study investigated the application of DCS in serious pediatric abdominal surgery.

METHODSThe clinical data of 49 children with serious abdominal diseases (age: 4 months to 10 years) were retrospectively studied. Of them, 32 children underwent damage control surgery (DCS) and 17 children underwent conventional operation. The preoperative critical severity score (CSS), postoperative temperature, blood pH and prothrombin time (PT), and the treatment outcome were compared between the DCS and the conventional operation groups.

RESULTSNo significant difference was found in the preoperative CSS between the two groups. There were significant differences in postoperative blood pH and PT values between the two groups (p<0.05). As for postoperative temperature, there was no statistical difference between the two groups, yet the tendency of temperature recovery in the DCS group was milder than that in the conventional operation group. Twenty-seven children (84.4%) were successfully cured in the DCS group, while 9 children (52.9%) in the conventional operation group (p<0.05).

CONCLUSIONSThe curative effect of DCS surpasses the conventional operation in children with serious abdominal diseases, suggesting that DCS is of value in the management of serious pediatric abdominal diseases.

Objective To discuss the changes and significance of interleukin-17 (IL-17) in perioperative period of congenital heart disease patients with pulmonary hypertension. Methods A total of forty patients with congenital heart disease underwent cardiopulmonary bypass (CPB) were included in this study. According to the pulmonary artery systolic pressure (PASP), patients were divided into non-pulmonary hypertension group (group Ⅰ, PASP < 30 mmHg) and pulmonary hypertension group (groupⅡ, PASP≥30 mmHg). Blood samples were taken before anesthesia (T1), start CPB (T2), 30 min after CPB (T3), 6 h (T4), 24 h (T5) and 7 d (T6) after operation. The concentration of IL-17 was detected by ELISA. Arterial oxygen partial pressure [p(O2)] and arterial carbon dioxide partial pressure [p(CO2)] during the first five time points were recorded. Oxygen index (OI) and alveolar arterial oxygen tension difference (AaDO2) were calculated. Results The plasma IL-17 levels in perioperative period were significantly higher in group Ⅱ than those of group Ⅰ (P < 0.05). The highest concentration of IL-17 emerged at T3, then decreased gradually in both groups. At this time point, the OI decreased, and AaDO2 increased significantly in both groups. Compared with groupⅠ, the OI decreased, while AaDO2 increased at T5 in groupⅡ(P<0.05). Conclusion The high level of IL-17 promotes the formation of pulmonary hypertension in congenital heart disease and leads to the lung injury during CPB, which can be used as a clinical monitoring indicator of evaluating severity.

OBJECTIVETo evaluate the clinical efficacy of bladder gasification and stasis dispersion combined with antibiotic therapy in the treatment of III A chronic prostatitis.

METHODSWe conducted a randomized controlled clinical study on 120 III A prostatitis patients that all met the diagnostic criteria. We divided the patients into groups A, B and C of equal number to receive oral medication of sparfloxacin, sparfloxacin + tamsulosin, and sparfloxacin + herbal decoction, respectively, all for a course of 4 weeks. We evaluated the primary therapeutic indexes according to the total scores of the patients on traditional Chinese medicine (TCM) syndrome and NIH-CPSI and the secondary therapeutic indexes based on the count of white blood cells (WBC) in the expressed prostatic secretion (EPS).

RESULTSAfter treatment, the total scores on TCM syndrome and NIH-CPSI were significantly reduced in groups B (42.15 +/- 10.29 and 13.25 +/- 6.04) and C (41.26 +/- 11.25 and 12.38 +/- 7.19) than in A (49.43 +/- 11.09 and 17.62 +/- 5.84) ( P < 0.05), and so was the WBC count in EPS in group C (7.76 +/- 15.73) than in groups A (11.45 +/- 10.33) and B (12.28 +/- 13.81) (P < 0.05). The difference between pre- and post-treatment scores on TCM syndrome was more significant in group C (12.65 +/- 11.76) than in B (8.55 +/- 10.15) (P < 0.05).

CONCLUSIONBladder gasification and stasis dispersion combined with antibiotic therapy is effective for the treatment of III A chronic prostatitis, and therefore deserves wide clinical application.
