Recently early noni-nvasive diagnostic techniques of bladder tumor are the hot resear- ches,which is significantly important for guiding clinical therapy and prognosis.This article will review the advancements of noninvasive diagnosis of bladder tumor in recent years and compare the new develop- ments with traditional exfoliative cytology test of urine,typical cystoscopy and improved cystoscopy.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective:To study the expression of coxsackievirus group B3 gene fragment encoding VP1 in procaryon and to explore its application.Methods:Stablie expression of VP1 gene of CVB3 in E.coli was obtained.The expressed protein was purified by NAT chromatography and its immunoactivity was identified by indirect ELISA.Results:The expressed product of VP1,similar to native protein antigen of CVB3,could strong bind with the mouse's antibody serum against CVB3(polyclonal antibody).Irrelevant monoclonal antibody as contrast presents negative activity. Using the expressed VP1 product,we have had a special IgM ELISA for the patient's serum of the clinical acute viral myocarditis.The result was same with the cellular protein antigens of the tissue-cultivated CVB3.Conclusion:The protein antigen CVB3-VP1 which is obtained by the method of gene engineering has character of high product, and its immunoactivity after being purified was basically unchanged. At present, this kind of antigen is difficult to be obtained from the viral cullture medium and a potent hazard for being infected by this virus may take place in such manipulateion. By the method of gene engineering we can obtain antigenic VP1 of CVB3 and use as immuneogen for the detection of serum antibody,by which to provide reliable test reference for the early-stage diagnosis and clinical therapy of the acute myocarditis.

OBJECTIVETo determine and evaluate the residuals of organochlorine pesticides and heavy metals in soil and in Pogostemon cablin in order to provide for GAP planting.

METHODGC method was applied to determine residuals of organochlorine pesticides, the contents of Pb, Cd, Cu, Cr, Hg and As were determined by IPC.

RESULTThe contents of residuals of organochlorine pesticides and heavy metals were different among three cultivars and planting bases clearly, but all of the residuals in soil from three planting bases were below the second standard of Environmental quality standard for soils (GB15618), and the residuals in P. cablin also meet the "Green standards of medicinal plants and preparations for foreign trade and economy".

CONCLUSIONResiduals of organochlorine pesticides and heavy metals in soil and P. cablin from three planting bases in Hainan province were conformed to GAP.

OBJECTIVE: To observe the origin, course and diameter of the metatarsal nutrient artery. METHODS: The metatarsaL nutrient in 90 feet, ranging in age from newborn to 87 years, were studied by perfusion method. The origin, course and diameter of these arteries were observed and measured. RESULTS: The diameter of the metatarsal nutrient artery was 0.24 approximate, equals 0.30 mm. The nutrient arteries of the first metatarsal bone originated from the deep plantar branch and the first metatarsal plantar artery in 59.6% of specimens, while the nutrient arteries of the other metatarsal bones mainly originate from the plantar metatarsal arteries, the plantar arch and its perfora-ting branches. The diaphysial nutrient foramina were situated in the middle third of the shaft over 90% of specimens. CONCLUSION: The metatarsal nutrient artery showes practical significance in clinic.

OBJECTIVETo explore the clinical and epidemiological characteristics of serious cases of hand-foot-and-mouth disease (HFMD) infected by EV71, in order to provide scientific evidence for prevention and control of HFMD.

METHODSInformation was collected by questionaires through consulting medical cases. Data was input by Epidata, and analysed by software SAS 9.13.

RESULT201 severe cases were investigated. 84.65% of the cases were below 3 years old. The youngest one was 5 months and the oldest one was 8 years old. The ratio for male and female was 2.2: 1.85. 08% of the cases were distributed sporadically. 51.74% of them lived in rural, 29.36% of them lived in urban and 19.9% of them lived at the fringe area of rural and urban. 81.59% of the cases became serious between 1 and 4 days after infected. 100% cases had fever and 99.95% of them had a rash. 96.52% of them had nerve system symptoms. The main complications were virulent spinal encephalitis, pneumonia and breathing exhaustion. 98.01% of the patients were recovered or cured.

CONCLUSIONThe cases aged below 3 years old are high risk persons. Rural area and the fringe area of rural and urban are the key area for disease control. 1-4 days after onset is the key period to prevent complications.
