Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Radiotherapy is one of the most important treatment method for esophageal cancer. Cene expression profile of cancer cells may be one of key factors in determining the effectiveness of radiation therapy To provide guidance for individual therapy, research advances in gene expression involved in radiosensitivity of esophageal cancer are discussed from three aspects: radiation damage repair, cell cycle distribution and signal traneduetion.

Polycystic ovary syndrome (PCOS) is a common syndrome in adolescent women and women of reproductive age. Main manifestations are oligomenorrhea, anovulation, polycystic ovarian, and hyperandrogenism with metabolic abnormalities such as dyslipidemia, insulin resistance, and glucose intolerance. PCOS can lead to type 2 diabetes mellitus, cardiovascular diseases, and endometrial cancer, which seriously threat the health of women. The pathogenesis of PCOS is not clear. Over 60% of women with PCOS are obese or overweight. Appetite and energy intake regulation plays an important role in body weight management. Nutrients are mainly digested and absorbed in gastrointestinal track, which is also one of the largest endocrine organs in human body. Special endocrine epithelial cells in stomach, proximal small intestine, and distal small intestine can secrete ghrelin, CCK, GLP-1, and PYY, which involve in the regulation of appetite and are also known as appetite regulating hormones. This review focuses on changes in the secretion of gastrointestinal hormones and related weight loss treatment in patients with PCOS.

The esophageal cancer mouse models have three categories:chemical carcinogenesis model,xenograft tumor model and genetic engineering model.Chemical carcinogenesis model can simulate well the pathological processes of human esophageal cancer and is prepared simply.Xenograft tumor model is currently the most commonly used esophageal cancer animal model,which has advantages of rapid tumor formation,higher tumor formation rate and lower cost.Genetic engineering model involves mainly p53,Cyclin D1,Brca1 and p120ctn,and it helps to understand the biological characteristics of tumors,but it is expensive and the preparation time is long.

OBJECTIVETo observe the therapeutic effects of steel plate fixation after the failure of arthrodesis of ankle by screw fixation.
METHODSFrom August 2001 to October 2011, 15 patients were with steel plate fixation after failure of arthrodesis of ankle by screw fixation. Among patients, 9 cases were males and 6 cases were females,ranging age from 40 to 65 years old with the average of 56 years old. Ten cases were in left and 5 cases were in right. Screws were removed and steel plate was fixed intraoperatively, and plaster external fixation for postoperation. Clincal effect were evaluated according to AOFAS scoring system from pain, waliking ability and aligment before and after operation, and X-ray was used to evaluate joint fusion after operation.
RESULTSAll patients were followed up, and the duration ranged from 4 months to 4 years with an average of 2 years. The incison were healed in stage I. No ankle pain,injury of blood vessel and nerve,infection and farilure of internal fixation occuerred. The AOFAS score increased from 36.86 +/- 8.32 preoperatively to 85.09 +/- 4.65 (t = -26.366, P = 0.000).
CONCLUSIONSteel plate fixation after the failure of ankle arthrodesis of screw fixation has the advantages of rigid stability, simple manipulation and high success rate, less pain, perfect recovery.

Objective The current study was designed to investigate the inhibitive effect of celastrol on the proliferation of acute myelogenous leukemia (AML) cells. Methods The effect of celastrol on AML cells in vitro was examined by MTT assay and flow cytometry (FCM). Results After the AML primary cells were treated with different concentrations of celastrol, the results were analyzed by MTT. The growth of the cells were significantly inhibited compared with the control group (P <0.01). The results detected by FCM showed that the apoptosis was seen after treated with celastrol with different concentration for different times.The apoptotic rates were significantly higher than that in the control group with statistical significance (P< 0.01).Conclusion Celastrol could inhibit the proliferation of AML cells in vitro, which may be associated with inducing cell apoptosis.

Objectives To observe the effect of Suanzaoren Decoction on the expression of NMDAR1, NMDAR2A and NMDAR2B RNA in cortex and hippocampus of depression model rats, and explore the mechanism of treating depression. Methods Ninty SD rats were randomly divided into blank group, model group, western medicine group, Suanzaoren Decoction high, medium and low dose group. Except the blank group, the other groups were replicated the rat model of depression in chronic stress. The treatment groups were given corresponding drugs by gavage. The expression of NMDAR1, NMDAR2A and NMDAR2B genes in cortex and hippocampus were detected by RT-PCR. Results Compared with the model group, the positive expression of NMDAR in cortex and hippocampus decreased in Suanzaoren Decoction high and medium dose group (P<0.01). The positive expression of NMDAR2A in cortex and hippocampus of Suanzaoren Decoction high, medium dose group and western medicine group decreased (P<0.05, P<0.01), the expression of NMDAR2A in hippocampus increased in Suanzaoren Decoction low dose group (P<0.05). The positive expression of NMDAR2B in cortex decreased in western medicine group, Suanzaoren Decoction high, medium and low dose group (P<0.01). The expression of NMDAR2B in hippocampus increased in Suanzaoren Decoction medium and low dose group (P<0.01). Conclusion Suanzaoren Decoction can play the role of treating depression by decreasing the expression of NMDAR1, NMDAR2A and NMDAR2B RNA in cortex and hippocampus.

Objective To evaluate the role of transient receptor potential ion channel 1 (TRPA1) in the spinal dorsal horn neurons in maintenance of neuropathic pain in rats.Methods Fifty-six adult male SpragueDawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =14 each):sham operation group (group S); chronic compression of dorsal root ganglia (CCD) group; CCD + dimethyl sulfoxide group (group D); and CCD + TRPA1 blocker HC-030031 group (group H).CCD was produced by infiltrating the L5 intervertebral foramen with 50 μl of a hemostatic matrix (SURGIFLO) in anesthetized rats in CCD,D and H groups.In D and H groups,10% dimethyl sulfoxide 20 μl and HC-030031 50 μg were injected intrathecally at 7 days after CCD operation,respectively.Paw withdrawal threshold to mechanical stimulation (PWMT) was measured at 1 day before operation (T0),at 1 h before intrathecal administration (T1),and at 1,2,4,6,8,and 24 h after intrathecal administration (T2-7).Six rats in each group were sacrificed at T4 and T7,the L3-5 segments of the spinal cord were obtained for determination of TRPA1 expression in the spinal cord by Western blot.Results Compared with group S,PWMT was significantly decreased at T1-7,the expression of TRPA1 in the spinal cord was up-regulated at T4 and T7 in CCD and D groups,and the PWMT was decreased at T1 and T5-7 and the expression of TRPA1 was up-regulated at T7 in H group (P < 0.05).Compared with CCD group,the PWMT was significantly increased at T2-5 and the expression of TRPA1 was down-regulated at T4 in H group (P < 0.05).Conclusion TRPA1 in the spinal dorsal horn neurons is involved in the maintenance of neuropathic pain in rats.
