Result Working condition, staff-member constitution, and finical investment were unoptimistic. However, the community health service centers consider the outcomes of community rehabilitation and management were satisfactory. Conclusion It should be necessary to facilitate the development of community mental health service system, achieve various community rehabilitation and health care, and improve social security system of community healthcare providers.

Objective To investigate whether recombinant human endostatin can create a time window of vascular normalization prior to vascular pruning to alleviate hypoxia in Lewis lung carcinoma in mice. Methods Kinetic changes in morphology of tumor vasculature in response to recombinant human endostatin were detected under a confocal microscope with immunofluorescent staining in Lewis lung carcinomas in mice. The hypoxic cell fraction of different time was assessed with immunohistochemical staining . Effects on tumor growth were monitored as indicated in the growth curve of tumors . Results Compared with the control group vascularity of the tumors was reduced over time by recombinant human endostatin treatment and significantly regressed for 9 days. During the treatment, pericyte coverage increased at day 3, increased markedly at day 5, and fell again at day 7. The vascular basement membrane was thin and closely associated with endothelial cells after recombinant human endostatin treatment, but appeared thickened, loosely associated with endothelial cells in control tumors. The decrease in hypoxic cell fraction at day 5 after treatment was also found. Tumor growth was not accelerated 5 days after recombinant human endostatin treatment. Conclusions Recombinant human endostatin can normalize tumor vasculature within day 3 to 7, leading to improved tumor oxygenation. The results provide important experimental basis for combining recombinant human endostatin with radiation therapy in human tumors.

Objective To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF)and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF.Methods One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF(the main stem of portal veins are visible).However,there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible).After the embolization,all of the 26 patients who have severe HAPVF stopped bleeding.Among them,the main stem of hepatic arteries are occluded in 2 patients. Conclusion The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients,and it can be diagnosed through hepatic artery DSA.Orifice embolization is the most effective method for such kind of hemorrhage.

The biological artificial liver(BAL) can offer reliable artificial liver support for the patients with hepatic failure.All BAL devices contain hepatocytes as their biological component,whose specific biological characteristics contribute to the function of the BAL.During the past two decades,various cells including human hepatocytes,heterogeneous hepatocytes and liver cell lines have been used and different culture methods have been studied to optimize the activity of the biological component.However,both functionality and safety of these cells should be improved before successful use in BAL. This paper summarizes the latest progress on it.

OBJECTIVETo deal with the correlation between phylogeny, chemical constituents and pharmaceutical aspects of Ranunculaceae, namely a pharmaphylogenic study of this taxon.

METHODBased on chemical, pharmaceutical (both ethnopharmacologic and pharmacological) information, linking with different plant systems of Ranunculaceae.

RESULTChemical constituents of this taxon included several natural groups: benzylisoquinoline alkaloid, ranunculin, triterpenoid glycoside and diterpene alkaloid etc. Ranunculin and magoflorine were found to present simultaneously in some plants of this taxon.

CONCLUSIONCombining with therapeutic information, pharmaphylogenic research were in accordance with the phylogenetic system presented by Tamura that Ranunculaceae was proposed to be divided into six sub-families: Helleboroideae, Ranunculoideae, Cimicfugoideae, Isopyroideae, Thalictroideae and Coptidoideae. Results also supported the establishment of Cimicifugoideae.

OBJECTIVETo study the pharmaphylogenetic of medicinal plants of Isopyroideae (Ranunculaceae).

METHODComprehensively analyze the correlation between phylogeny, chemical constituents and pharmaceutical aspects of Isopyroideae plants, based on chemical, pharmaceutical (both ethnopharmacologic and pharmacological) information, linking with different plant systems of Ranunculaceae.

RESULTPlants from Aquilegia mainly contain flavonoids constituents while the major chemical constituents of Isopyrum are bisbenzylisoquinoline alkaloids. Chemical characteristics also support that this taxon should be separated from Thalictrodeae, and constituted an independent subfamily, namely, Isopyroideae.

OBJECTIVETo investigate the effect of heat exposure during the second week of pregnancy on placental development and intrauterine growth of fetal rats.

METHODS24 pregnant rats were either exposed or not to a temperature of 35∓1 degrees celsius; during the second week of pregnancy. The body weight gain of the pregnant rats was measured regularly, and in late pregnancy, the pregnant rats were dissected and the number, weight, length, tail length, appearance of the offspring rats, number of live and still births, and the placental weight were recorded. The expressions of HSP70, Bax and Bcl-2 in the placenta were determined.

RESULTSCompared with the control group, the pregnant rats in heat exposure group had significantly lower body weight at the end of pregnancy and gestational weight gain, and the body weight, body length and tail length of the offspring rats were also significantly lower or smaller (P<0.05). The placental weight was comparable between the two groups. The placental expressions of HSP70,Bax,and Bcl-2 were significantly higher in the heat exposure group than in the control group (P<0.05).

CONCLUSIONHeat exposure during the second trimester of pregnancy has adverse effects on placental development and intrauterine growth of the fetal rats by inducing heat shock response of placental tissue and apoptosis of the placental cells.

OBJECTIVETo summarize the change of bladder tumor cells in irrigating solution after partial cystectomy by 2 microm continuous wave laser.

METHODSFrom May 2008 to December 2008, a total of 30 patients of bladder cancer, the diameters of tumors from 0.5 to 3.0 cm. The diameter being regarded as the standard, patients were divided into two groups, 10 cases in group A (diameter < 2.0 cm) 20 cases in group B (diameter >or= 2.0 cm). The pre-operative pathologic histology diagnoses of all patients by biopsy were bladder urothelial carcinoma. Partial cystectomy by 2 microm continuous wave laser was given in operation. Due to the patients in group a with smaller tumors, the tumors were washed out of the bladder through the sheath of cystoscope directly. In group B, the larger tumors were cut into blocks by laser in the bladder, and washed out. After removing the tumors and debris, bladder irrigation was performed with about 150 ml solution for 5 times, then irrigating solution was centrifuged and numbered respectively before cellular pathology examination.

RESULTSIn group A, there were no tumor cells but epithelial cells and red blood cells could be seen in 8 cases. In the other 2 cases, a small amount of integrity and shape broken tumor cells could be seen in the No.1 and No.2 piece. There was no tumor cell in No.3, No.4, and No.5 pieces. In group B, tumor cells can be seen in No.1, No.2 and No.3 pieces in 14 cases, but cell density decreased gradually. There was no tumor cell in No.4, No.5 pieces, and tumor cells can be seen in No.1 to No.4 pieces for another 6 cases, and cell density also decreased gradually, there was no tumor cell in No.5 piece.

CONCLUSIONAfter the surgery, 5 times of bladder irrigation in all cases of partial cystectomy by 2 microm continuous wave laser can reduce the remnants of the bladder tumor cells effectively.
