AlM:To investigate biological measurement parameters of anterior segment in acute angle- closure glaucoma ( AACG) .METHODS:Forty-six eyes of 46 patients with AACG and 52 eyes of 52 patients with shallow anterior chamber and 50 eyes of 50 normal individuals were examined. The parameters of anterior segment including chamber crowd rate (CCR), lens thickness (LT), lens position (LP) and anterior chamber depth ( ACD ) were measured by A-ultrasound according to different ages in each group. The data were performed statistical analysis in three groups.RESULTS: ln each age range group (≥50 ~ 59 years old, ≥60 ~ 69 years old, ≥70 years old ) , statistically significant differences in three groups ( AACG, shallow anterior chamber group and the controls ) were found in CCR, LT, LP, ACD (P<0. 01). There were statistically significant differences only in CCR (P<0. 01) but not in LT, LP and ACD ( P > 0. 05 ) between AACG and shallow anterior chamber group in each age range group.CONCLUSlON: CCR can be used as the index of evaluating crowding state of anterior segment in AACG patients and the sensitivity is better than LT and LP.

Cinobufacino injection is a significant anti-tumor medicine for the treatment of various tumors in clinic, which was made from water extraction of the skin of Bufo bufo gargarizans. In present paper, HPLC-DAD-FT-ICR-MS method was used to identify the major bufadienolides in cinobufacino for the first time. Solid-phase extraction with dichloromethane and silica was used to enrich the total bufadienolides in cinobufacino. Based on the UV and high resolution MS/MS data, 33 bufadienolides were analyzed and characterized. Among them, eight compounds were identified by comparing with standard references unambiguously. This study elucidated the major bufadienolides in cinobufacino, which provided material foundation of cinobufacino and will be benefit for the further pharmacological research.

Objective: To observe the clinical effect of treating remission-stage cerebral infarction with mind-refreshing and orifice-opening needling method. Method: Six hundred cases of cerebral infraction were randomized on the basis of disease phase. The 234 cases in remission stage were randomized into treatment group (116 cases) and control group (118 cases). Besides routine Western therapies, the cases in the treatment group were combined mind-refreshing and orifice-opening needling method and the cases in the control group were combined with conventional needling method. The treatment was done once every day for 4 weeks. The follow-up was done for six months. Result: the baseline material in the two groups has good compatibility (P>0.05) and the treatment group is better than the control group (P<0.05). Conclusion: the mind-refreshing and orifice-opening method is safe and act to improve symptoms of patients during remission stage, reduce disability, prevent disease progression and improve quality of life.

OBJECTIVETo investigate the relationship between beta-catenin and matrix metalloproteinase-7 (MMP-7) expression and development/biologic behavior of human colorectal cancer.

METHODSImmunohistochemical study for beta-catenin and MMP-7 was carried out on colorectal adenoma-carcinoma tissue microarrays and results analyzed.

RESULTSThe nuclear beta-catenin expression rate was 35.9% in adenoma with malignant transformation, significantly higher than that in adenoma (16.7%) and carcinoma (19.7%) (both P < 0.05). The cytoplasmic and nuclear beta-catenin expression rate in adenoma with severe dysplasia was significantly higher than that in adenoma with mild dysplasia (both P < 0.05). The nuclear beta-catenin expression rate in adenocarcinomas of the ulcerative type, with lymph node metastasis and in the late tumor stages were all significantly higher than that in adenocarcinomas of the polypoid type, with negative lymph node and in the early tumor stages (P < 0.05 or P < 0.01). The MMP-7 expression rate in adenocarcinoma (69.2%) was significantly higher than that in normal colorectal mucosa (15.0%), adenoma (35.0%) and adenoma with malignant transformation (46.2%, P < 0.05 or P < 0.01). The MMP-7 expression rate in ulcerative type adenocarcinoma with lymph node metastasis and in late tumor stages was significantly higher than that in polypoid type adenocarcinoma with negative lymph node and in early tumor stages (all P < 0.05). The cytoplasmic and nuclear beta-catenin expression was thus in positive correlation with the expression of MMP-7 (both P < 0.01).

CONCLUSIONSThe cytoplasmic and nuclear beta-catenin expression, probably an early event, was related to the development of colorectal cancer. beta-catenin may enhance the degradative function of the target gene MMP-7 through nuclear translocation and may further facilitate local invasion and metastasis by the colorectal cancer cells.

Objective To understand the current status of the prevention and control of endemic fluorosis in the southwestern area of Shandong province. Methods In 2007, the progress of water-improving defluoridation, the operating state and water fluoride content of the water-improving project, which was determined by fluorosis selective ion electrode, and the inhabitant related indexes of endemic fluorosis were extensively surveyed in the three main fluorosis counties-Jiaxiang, Yuncbeng and Liangshan of the southwestern area of Shandong province. Results Among 1371 fluorosis villages in the 3 counties, 53.61%(735/1371) of which had undergone water-improving defluoridation, the rate in Jiaxiang, Yuncheng and Liangshan being 38.0% (220/579),65.51% (378/577) and 63.72% ( 137/215 ) respectively; the normally functioning rate of this project was 76.73% (564/735), projects out of order accounted for 23.27% (171/735). Among 263 well-functioning projects from the three counties, the rate with water fluoride higher than 1.0 mg/L was 35.36%(93/263), the maximum value being 4.17 mg/L. The urine fluoride content of 440 children aged 8 - 12 years and 484 adults over 30 years old were examined in 13 fluorosis villages of the three counties, the geometric mean was 2.98,3.06 mg/L respectively; the individual maximum was 12.83,14.49 mg/L respectively; the detectable rate of dental fluorosis among children aged 8 - 12 was 84.28% (649/770) ,17.66%(136/770) had defect and the index of dental fluorosis was 1.89; the rates of the clinical and X-ray skeletal fluorosis of the adults aged more than 30 were 44.40%(234/527) and 24.67%(130/527) respectively, and the abnormal electrocardiography rate was 32.43% (168/518) in the adult, mostly T-wave abnormality. Conclusions The progress of the water-improving defluoridation in the southwestern area of Shandong province was relatively slow, the water fluoride content of the water-improving projects seriously exceeded standard, and the condition of the fluorosis had not been effectively controlled.

Objective To understand the fulfillment of control measures of endemic fluorosis and find out the prevalent trend of this disease in Shandong Province from 1992 to 2006 in order to provide a scientific basis for the set up of control strategies. Methods According to "the National Survey Scheme of Endemic fluorosis", Huantai County in 1992-1996 and Liaagshan County in 1997-2006 were selected, where water-improving defluoridation and the contents of water fluoride were searched in two counties; dental fluorosis and urine fluoride in children aged 8-12 years old, clinical and X-ray skeletal fluorosis in adult over 16 years old were searched respectively in Lijia Village of Huantai County and Dongxu Village of Liangshan County. Results One hundred percent(304/304) high-fluoride villages of Huantai County in 1992 and 63.72% (137/215) villages of Liangshan County in 2006 had finished the project of water-improving defluoridation; the rate of high-fluorine water(>1.0 mg/L) in normal operation projects was 5.00%(5/100)-17.14%(18/105) in Huantai County from 1992 to 1996, and 18.97%(11/58)-45.61%(26/57) in Liangshan County from 1997 to 2006. The water fluoride of Lijia Village was<1.0 mg/L from 1992 to 1996, the water fluoride of Dongxu Village was<0.5 mg/L from 1997 to 2006. The detection rate of dental fluorosis of children aged 8-12 years at Lijia Village dropped from 30.86%(25/81) in 1992 to 10.13%(8/79) in 1996(χ2=12.41, P<0.05), and the Dongxu Village dropped from 68.95%(151/219) in 1997 to 0(0/38) in 2006(χ2=222.04, P<0.01). In the Lijia and Dongxu Villages, urine fluoride in children aged 8-12 years old was lower than 1.40 mg/L. In the adults over 16 years of the two villages, the positive rate of X-ray skeletal fluorosis of Lijia Village dropped from 30.0%(15/50) in 1992 to 13.95%(6/43) in 1996(χ2=3.41, P>0.05), and all the cases were in degree I, the rate of Dongxu Village dropped from 64.58%(31/48) in 1997 to 16.67% (4/24) in 2006(χ2=14.71, P<0.01), and no eases of degrees Ⅲ was detected. Conclusions The progress of water defluoridation was uneven in 2 counties, slow in Liangshan County; and the water fluoride in part of the project exceeded standard; the water fluorid of 2 surveyed villages was normal and the endemic fluorosis was under control. More financial input is requested to accelerate the process of water defluoridation and to reinforce the management of the projects and illness monitoring, thus to reduce the harm of fluorosis to the limit.

OBJECTIVE To observe renal protective effect and possible mechanism of absorbed bioactive compounds (ABCs)of Danggui Buxue Decoction on GK rats.METHODS The qualitative and quantitative analysis of ABCs of Danggui Buxue Decoction were performed by UPLC-MS/MS and the composition of ABCs were determined.Then the ABCs concentra-tion of 1 g mother decoction was quantified.GK rats were randomly divided into model group,decoction group and ABCs group (n=10).Treatment groups were administered Danggui Buxue Decoction(4 g/kg)or ABCs(equal to the content of decoction, caffeic acid 5.36 mg/kg,formononetin 2.68 mg/kg,calycosin 2.56 mg/kg,ferulic acid 1.36 mg/kg,astragaloside 0.45 mg/kg,butyphthalide 0.16 mg/kg,ligustilide 0.16 mg/kg),once a day for 28 d.10 Wistar rats were chosen for control group and treated with vehicle(saline).Observation index:urinary total protein and urinary albumin,oxidative stress in kidney and the pathological observation of kidney.RESULTS Danggui Buxue Decoction and ABCs significantly decreased urinary total pro-tein,urinary albumin of GK rats and the level of MDA of kidney(P<0.05),significantly increased the activity of SOD of kid-ney(P<0.05)and displayed a protective effect on kidney pathomorphology.CONCLUSION ABCs can represent Danggui Buxue Decoction play a renal protective effect on GK rats,the mechanism involving oxidative stress.However,except for ABCs,the trace elements,amino acids,polysaccharides and other ingredients in mother decoction also play significant roles.

OBJECTIVETo investigate the effect and safety of zoledronic acid (Zoledex) in patients with cancer-induced hypercalcemia.

OBJECTIVETo investigate the safety and feasibility of testis-sparing surgery (TSS) in the treatment of testicular tumor.

METHODSWe retrospectively analyzed the clinical data of 8 cases of benign testicular tumor treated by TSS in our hospital from October 2005 to March 2012.

RESULTSThe 8 patients, aged 18-67 (mean 45) years, were preoperatively diagnosed with benign testicular tumor and all underwent partial testis resection. Rapid intraoperative pathology showed the incisal margins to be negative. Postoperative pathological examination confirmed Sertoli cell tumor in 3 cases, adenomatoid tumor in another 3, and mature teratoma in the other 2. The patients were followed up for 6 months to 7 years (mean 4 years), which revealed no relapse and metastasis, nor significant differences from the baseline in the testosterone level, IIEF score, and routine semen parameters.

CONCLUSIONTestis-sparing surgery is one of the effective options for the management of benign testicular tumor, which can maximally preserve the testis tissue and protect the patient's sexual function.
