The younger groups scored higher in social stressor and SCL-90 than older group. Conclusion: The result showed the latter education can improve mental health.

In the structural determination of natural glycosides, nuclear magnetic resonance (NMR) is an important approach in determining the configuration of glycoside bond. The test of coupling constant of the anomeric proton and chemical shift of the anomeric carbon are two common methods, but these methods are not suitable for some sugars. For those sugars, detailed 13C NMR analysis is an alternative choice. This paper summarizes the characteristics of 1H and 13C NMR data of the common monosaccharides published in the literatures, in order to search an approach to determine the configuration of glycoside bond.

AIM:To study and compare the outcomes of coaxial 2. 2 mm phacoemulsiflcation with conventional coaxial 3 mm small-incision cataract surgery.
METHODS: A randomized prospective study was conducted on 100 patients with age - related cataract:coaxial 2. 2 mm micro - incision cataract surgery was performed in 50 cases (50 eyes), and coaxial 3 mm small incision cataract surgery was performed in 50 cases ( 50 eyes) . Statistical analysis was takenwith the data of the two groups. Visual acuity, VF and QOL were compared at intervals of 1wk and 3mo after surgery. In addition, surgically induced astigmatism ( SIA ) was analyzed. Statistic analysis was taken by Student's t-test and Chi-square test.
RESULTS:There was no significant difference on BCVA (t=-1. 366, -1. 688; P=0. 148, 0. 107) between these two groups. One week and 3mo after the surgery, SIA was (0. 46±0.29)D, (0. 43±0. 26)D in the 2. 2 group; and (1. 55±0. 59) D, (0. 89±0. 28) D, in 3. 0 group. The differences between these two groups were statistically significant ( t=-7. 348, -3. 788; P = 0. 000, 0. 000 ) There were no statistically significant differences on VF scores between two group, while it's got a better score in 2. 2 groups on vision adaptation. (t=-3. 348, P<0. 05).
CONCLUSION:Coaxial 2. 2mm micro-incision cataract surgery could significantly reduce SIA and obtain morestable status of VF and QOL. This suggests that the coaxial 2. 2 phacoemulsification surgery implanted AkreosMI60 intraocular lens could get earliervisual rehabilitation postoperation.

Objective The present study was designed to investigate the efficiency of simvastatin therapy for experimental pul‐monary hypertension (PH) in rat ,and the effects on the number and function of circulating endothelial progenitor cells (EPC) . Methods Twenty four Sprague Dawley rats were divided into 3 groups randomly :model group ,treatment group and control group , 8 rats in each group .Rats were treated with a single subcutaneous injection of monocrotaline to induce PH (PBS used as control) . The rats in the experimental group were administrated with simvastatin 3 days following subcutaneous injection of monocrotaline .In the 21st day ,the number of circulating EPC ,the right ventricle systolic pressure of rat ,pulmonary vascular structural changes and the quantity of cultured EPC were measured .At the same time ,EPC in each group were cultured in vitro ,then the ability of prolif‐eration and function were analyzed and compared .Results The number of circulating EPC in model group was decreased signifi‐cantly compared to both control and model groups (P< 0 .01) .Compared with model group ,simvastatin treatment markedly de‐creased the RVSP and the ratio of media thickness to eternal diameter (P<0 .01) ,but the ratio of vessel area to total arterial area (VA/TAA) was definitively increased(P<0 .01) .After 7 days of culture in vitro ,both the output of EPC and the ability of prolif‐eration ,conglutination and migration of EPC in treatment group were up -regulated compared with those in model group (P<0 .01) .Conclusion This study confirmed that simvastatin effectively treat experimental PH through improving quantity and func‐tion of circulating EPC .

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

Objective To investigate the distribution of water-borne fluoride and the current status of water defluoridation project by improving drinking water quality in endemic fluorosis areas in Shandong province,and to provide scientific basis for making strategies in prevention and control of the disease. Methods According to "the National Technical Scheme for Endemic Disease Control in 2004, 2005 and 2006", 113 endemic fluorosis diseased counties(cities, and districts) of the province's 17 cities were screened in order to investigate the fluoride level in drinking water in fluorosis villages, recheck the fluoride level after implementing the water defluoridation project, and investigate the current status of the water defluoridation project. The fluoride level in drinking water was determined by F-ion selective electrode. Results There were a total of 5816 water defluoridation projects in the province. Most of them were carried out by drilling a deep well to get under-ground water. The wells still in good condition were accounted for 72.80% (4234/5816). Intermittent operated wells were accounted for 3.11% (181/5816). Abandoned wells were accounted for 24.09%(1401/5816). Level of water fluoride was determined in 6940samples from fluorosis villages(villages that not carry out the water defluoridation project as well as villages carried out the water defluoridation project with abandoned wells were included) and the value that lower or equal to 1.00mg/L was determined in 2987 villages which accounted for 43.04% (2987/6940). Level of water fluoride that over 1.00 mg/L was found in 3953 villages which accounted for 56.96% (3593/6940), and the highest level of water fluoride was 11.33 mg/L. Level of water fluoride were determined in 4415 samples from water defluoridation project and the value lower or equal to 1.00 mg/L was in 2983 wells which accounted for 65.53%(2983/4415). The value over 1.00 mg/L was in 1522 wells which accounted for 34.47%(1522/4415), the highest value of water fluoride was 9.71 mg/L. Conclusions Level of water fluoride in up to 1/2 of the villages and 1/3 of the projects, is still higher than the standard in Shandong province. Nearly 1/4 of the project has been abandoned. The current situation for endemic fluorosis control is still not good in the province, countermeasures for endemic fluorosis must be carried out as soon as possible and surveillance of water defluoridation project must be strengthened.

Objective To discuss the value of moving darkroom and accompanying X-rays protective shield in endemic fluorosis areas.Methods Using moving and fixed darkrooms,the X-rays photos of the forearms and shanks of the 320 persons were developed in the endemic fluorosis areas,while the time for development and installing-uninstalling films was documented.The films develpoed in the darkroom were evaluated for the quality.Results Among the 320 films develpoed in the moving darkroom,the 268 had fingerprints,47 had scratches,298 were in good quality(93.13%),while in the fixed darkroom,the figure was correspondingly 735,384,227(70.93%);The moving darkroom increased excellent film rate significantly than fixed darkroom(χ2=53.43,P＜0.01),The detectable rate of skelelal fluorosis and degree Ⅰ skelelal fluorosis were highter than that in the fixed darkroom did (χ2=10.34,χ2=9.56,P＜0.01).Conclusions The films developed in moving darkroom have superior quality and higher diagnostic value,so it is important to use moving X-rays photographing in ecdemic fluorosis areas.

Background and purpose:Liver cancer resection and splenectomy are the main methods to treat hepatocellular carcinoma and hypersplenism. The aim of this study was to discuss the safety and feasibility of simultaneous radiofrequency ablation (RFA) and laparoscopic splenectomy (LS) for the treatment of small hepatocellular carcinoma with hypersplenism.Methods:Twenty-seven patients with small hepatocellular carcinoma and cirrhotic hypersplenism underwent RFA and LS. The clinical data were also analyzed.Results:The surgery was converted to an open surgery in 1 patient, while laparoscopic splenectomy in a hand-assisted manner was performed in 2 patients. There were 31 liver tumors treated with RFA. Blood loss were 110-900 mL (mean=320 mL). Operation time were 72-127 min (mean=107 min). Subcutaneous emphysema occurred in 1 patient, and pancreatic leakage in another patient. Nine patients developed ascites. one patient suffered from massive haemorrhage, and emergency operation was adopted to stop bleeding. This patient recovered well after operation. No death was found during the hospitalization. Conclusion:Combining RFA with LS for the treatment of liver cancer and hypersplenism is minimally invasive, safe, and feasible.

OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.

METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.

RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).

CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.
