To observe the therapeutic effect of acupuncture plus TDP irradiation on proliferative arthritis, 304 patients with proliferative arthritis were randomly divided into treatment group and control group, and treated by acupuncture plus TDP irradiation and routine Tuina respectively. The clinical cure rate and total effective rate in the treatment group were both superior to those in the control group. This therapy has good therapeutic effect and short course of treatment in treating proliferative arthritis, and is one of better therapeutic means in clinic presently.

Irritable bowel syndrome(IBS)is a commonly seen functional gastrointestinal disorder. Its main clinical manifestations were abdominal pain,abdominal distention and altered bowel habits. Currently,the pathogenesis of IBS has not been clarified. Studies showed that IBS was caused by many factors,including life style,gene polymorphism,food hypersensitivity,psychological factors,brain-gut axis abnormality and intestinal flora disorder. This article reviewed the advances in study on pathogenesis of IBS.

During L-lactic acid fermentation with Rhizopus oryzae,there existed a branch pathway by which pyruvate was transformed to eth- anol catalyzed by pyruvate decarboxylase(PDC)and alcohol dehydrogenase(ADH),thus decreasing the flux of pyruvate to lactic acid.In this study,the spores of Rhizopus oryzae AS3.3462 mutagenized with nitrosoguanidine(NTG),the appropriate dosage was 0.15 mg/mL and the lethal rate was 70%～80%.Two mutants,named mut-1 and mut-2,with decreased ADH activity were screened out by yeast peptone dextrose(YPD)agar medium containing allyl alcohol.These two mutants had decreased ADH activities of 41.63% and 50.29% compared with the parent strain.The fermentation behavior after 72h showed that the yields of ethanol produced by mut-1 and mut-2 were 4.87g/L and 6.56g/L respectively,while the wild type strain was 28.9g/L,and the lactate concentrations of mut-1 and mut-2 also increased from 40.31g/L to 54.45g/L and 44.07 g/L,respectively.It is also found that mut-1 and mut-2 had a high reducing sugar consumption rate and biomass accumulation than its present strain

Objective To study the pathological characteristics of allied Hirschsprung's disease (allied HD) by using NSE and S-100 protein immunohistochemical markers techniques,improve the early diagnosis rate. Methods 97 cases with HD were included in this study.The morphological and numeral change of the neuron and ganglion cell of the lesions was observed and compared with the normal controls.NSE and S-100 protein immunohistochemical markers were performed in 21 cases.Result The number of the neuron and ganglion cell of allied HD was statistically significantly higher than those in the normal control or HD group (P

AIM: To explore the effect of early posterior approach vitrectomy in the treatment of penetrating ocular trauma with intraocular foreign body.METHODS: Totally 10 cases of penetrating ocular trauma with intraocular foreign bodies(IOFB) in the past two years were included.Emergency vitrectomy, intraocular foreign body removal and silicone oil tamponade were performed by the same surgeon.Antibiotics and steroids were given after surgeries.Retinal photocoagulation was done according to fundus conditions after surgeries.RESULTS: One patient combined with preoperation endophthalmitis and severely damaged retina failed to recover, eventually came to phthisis bulbi.Vitrectomy and IOFB removal were all successfully performed in the other patients.The postoperation follow-up time was 3-18mo.Two of the patients received secondary vitrectomy and silicone replacement surgeries due to recurrent retinal detachment.The remaining patients had no further bleeding with intraoclar pressure(IOP) 8-21mmHg.At the last follow-up, three of them gained best corrected visual acuity better than 0.1, two patients had visual acuity of 0.01 to 0.1 and four patients had poor visual acuity of light perception to FC/50cm because of macular damage.The patient with phthisis bulbi had no light perception.CONCLUSION: Early vitrectomy, foreign body removal and silicone oil tamponade is an effective treatment for patients with penetrating eyeball injury with IOFB.

Good doctor-patient communication is the most effective way to build a harmonious doctor-patient relationship and reduce medical disputes, where the communication skill is the key. In communication with the hospitalized patients, it should pay attention to the communication object choice;the choice of the communicator;communication time, location and the form; pay attention to the communication protocol; using a comprehensible language communication;stand in the perspective of patients in order to enhance the doctor-patient trust and im-prove the doctor-patient relationship.

Objective To study the effects of different doses of UVA1 on the development of hypertrophic scar in rabbit ears induced by excision of full-thickness skin. Methods A hypertrophic scar model was established by excision of full-thickness skin (2 cm×5 cm) on the ventral surface of rabbit ears. A total of 18 New Zealand rabbits were randomly divided into 3 equal groups to receive UVA1 radiation on the left ears immediately, 1 month, and 2 months after the excision, respectively, and every group were classified into two subgroups to be irradiated with 60 and 110 J/cm2 of UVA1, respectively, for 30 sessions. The right ears served as control without irradiation. HE staining and Masson staining were used to examine the dermal thickness and collagen content in scar, respectively. Results Compared with pre-irradiation, the dermal thickness (t = 5.85, 4.94, respectively, both P＜0.05) and collagen content (t = 6.50, 8.02, respectively,both P＜0.05) significantly decreased in scar irradiated with UVA1 of 110 J/cm2 one and two months after the excision. The difference value in dermal thickness and collagen content at the beginning and at the end of the study significantly differed between irradiated and non-irradiated ears in the rabbits treated with UVA1 of 110 J/cm2 (P＜0.05). The effects of UVA1 on dermal thickness and collagen content were dose-dependent (P＜0.05). On the contrary, the dermal thickness and collagen content markedly increased in scars of rabbits irradiated with UVA1 immediately after the excision (P＜0.05 ). Conclusions To begin UVA1 exposure of hypertropic scar in rabbits after epithelialization may lead to the softening of scar, thinning of skin, and decrease of collagen content. However, immediate irradiation with UVA1 after wound could not prevent the development of hypertrophic scar in rabbits, in contrast, it exacerbated the severity of scar.

Stereotactic body radiation therapy (SBRT) adopts different tumor-killing mechanisms from the conventional fractionated radiotherapy.In SBRT,a single high-dose radiation can destroy the membrane of tumor cells and induce the release of tumor-associated antigen,also named in situ tumor vaccine,which stimulates the immune system to kill the residual tumor;a single-fraction radiation with a dose larger than 8-10 Gy can induce rapid apoptosis of vascular endothelial cells via the acid sphingomyelinase pathway at 1-6 hours after radiation,which causes tumor vascular occlusion and secondary tumor-killing effects.In order to understand whether SBRT improves the clinical treatment outcomes via the above mechanisms,this paper reviews the clinical research advances in SBRT for primary liver cancer.

Objective To study the epidemiological features of prevalence and distribution of diabetes mellitus (DM) and the injury glucose tolerance (IGT) in elder people in Beijing. Methods Cross over sectional epidemiological survey by random stratified sampling method in elder population was applied and the middle aged people was used as controls. The prevalent status of diabetes and IGT in the population more than 60 years old in urban area was compared with that in rural areas in Beijing in 1997. Results The aggregate age adjusted standardization prevalence of diabetes and IGT were 15 98% and 15 89% , respectively in old age population in Beijing in 1997. Diabetes prevalence in 60 69 years group (only comparable data) increased about 3 2 times from 4 27% in 1981 to 13 73% in 1997. Although it was no difference in IGT prevalence between urban and rural elders, there existed significant difference for diabetes standardized rates between them(17 74% vs 8 83%). The characteristics that diabetes occurrence increased with aging has been confirmed by the correlation of diabetes prevalence to the aging in both middle age( r =1 00, P
