1.A New Spot Test Method for Nitrite in Water
Journal of Environment and Health 1993;0(03):-
Objective To introduce a rapid spot test method for nitrite in water to meet the urgent need of nitrite monitoring during accidental pollution. Methods According to the drinking water legislation in Europe (threshold: 0.10 mg/L NO2-), a rapid spot test method for nitrite in water was established by using an optimized composition of reagent mixture and a binary positive/negative response, conducted as follows: a tablet of a mixture of solid reagents containing sulfanilamide, N-(1-naphthyl) ethylene diamine dihydrochloride and sodium chloride was put on a spot test plate of Teflon mould, then, a drop of 30%(V/V) HCl and a drop of water sample were added on the reagent material. Results Under these conditions, all the test samples containing ≥0.10 mg/L NO2- can produce a positive response of the characteristic red-purple color, whereas, the samples will produce a negative response when the level of NO2- was below the limit. The results of real water samples determined with this new method were confirmed by using the photometric method based on the use of the same reagents. Conclusion The method is simple, rapid , accurate, and suitable for field monitoring of nitrite in water.

Chinese Journal of Primary Medicine and Pharmacy 2013;20(14):2117-2118
Objective To study the clinical effect of surgery combined with antifungal drug in treatment of fungal nose-sinusitis.Methods The clinical data of 108 cases with fungal nose-sinusitis were retrospectively analyzed.All patients were treated with nasal endoscopic sinus surgery.According to whether the patients received antifungal drugs after low-temperature plasma-assisted surgery,the patients were divided into the treatment group and the control group.The treatment group(56 cases) was given antifungal fluconazole after low-temperature plasma-assisted endoscopic sinus surgery.52 cases in the control group were washed by 0.9% sodium chloride solution after conventional endoscopic sinus surgery.The patients were followed up for 6 months to 2 years,the therapeutic effect and recurrence were compared between the two groups.Results 56 patients of the treatment group,49 cases were cured,7 cases improved,no recurrence.52 cases in the control group,47 cases were cured,improved in 4 cases,ineffective in 1 case,3 cases of recurrence.The recurrence rate of the treatment group was significantly lower than the control group (x2 =4.82,P < 0.05).Conclusion The low-temperature plasma-assisted surgery combined with antifungal drug.in the treatment of fungal nose-sinusitis has exact efficacy,and has significant effect on the prevention and reduce the relapse rate,which worthy of clinical promotion.

6.Study on the relationship of omentin-1 in coronary heart disease patients with different glucose tolerance
The Journal of Practical Medicine 2014;(4):542-545
Objective To investigate the relationship between omentin-1 and Coronary heart disease in different glucose tolerance populations. Methods Serum omentin-1 levels were determined by ELISA in 143 subjects with normal glucose tolerance,impaired glucose tolerance with CHD, type 2 diabetes mellitus with CHD. The relationships between omentin-1 and waist- to-hip ratio, body mass index (BMI), blood Glucose, serum insulin,HOMA-IR and blood fat were also explored.Coronary artery stenosis was screnned by coronary interventional angiography and assessed by Gensini scoring system. Results Serum omentin-1 levels were all lower in T2DM and IGT subjects than those in control subjects (P<0.01). Serum omentin-1 was correlated positively with high density lipoprotein-cholesterol (P < 0.01),and inversely with body mass index,waist-hip ratio,diastolic blood pressure, triglyceride,fasting blood glucose,fasting insulin,HbA1c,[w1]and insulin resistance(HOMA-IR)(P<0.05 or P <0.01).Omentin-1 levels was negative related with Gensini coronary artery score (P < 0.01). Multiple linear regression showed body mass index,HOMA-IR,diastolic blood pressure were independently associated with omentin-1 levels (P<0.05 or P<0.01). Conclusions Serum omentin-1 levels, associated with fat,insulin sensitivity, are likely to play an important role in insulin resistance and the development of CHD in populations with different glucose tolerance.

Chinese Journal of cardiovascular Rehabilitation Medicine 2014;23(4):392-395
Objective:To explore the influence of diabetic self-management education on blood glucose control and inflammatory factor levels in inpatients with diabetes mellitus (DM).Methods:A total of 168 DM patients,who hospitalized in department of endocrinology in 163rd hospital of Chinese PLA from Jun 2012 to Jun 2013,were ran-domly divided into self-management education group (self-management group,n=88)and routine health education group (routine management group,n = 80).Self-management group received self-management education course namely AADE7TM ,provided by full-time DM health education staff,including healthy eating,being active,monito-ring,taking medication,problem solving,healthy coping and reducing risks,while routine management group re-ceived routine DM health education.Blood glucose control,changes of levels of myeloperoxidase (MPO),tumor necrosis factor-α(TNF-α)and intercellular adhesion molecule-1 (ICAM-1)were examined before and after interven-tion.Results:Compared with before intervention,there were significant reductions in levels of fasting blood glucose (FBG),postprandial blood glucose (PBG)and glycosylated hemoglobin (HbA1c)in both groups after interventions (P <0.05 all).Compared with routine management group,there were significant reductions in levels of FBG [(7.1 ±1.3)mmol/L vs.(6.0±1.1)mmol/L],PBG [(9.5±1.6)mmol/L vs.(8.8±1.4)mmol/L]and HbA1c [(7.9 ±1.5)% vs.(7.2±1.1)%]in self-management group,P <0.05 all.Before discharge,there were significant de-crease in inflammatory factor levels in both groups compared with before intervention (P < 0.05 all).Compared with routine management group after intervention,there were significant decrease in inflammatory factor levels [TNF-α:(201.0±57.3)pg/ml vs.(100.7±49.2)pg/ml,ICAM-1:(25.2±3.6)ng/ml vs.(18.2±2.9)ng/ml] in self-management group,P < 0.05 both.Conclusion:Self-management education provided by full-time diabetic health education staff is superior to routine diabetic health education method in controlling blood glucose and decrea-sing inflammatory factor levels,indicating it can improveβcell function and relieve insulin resistance.

China Pharmacy 2016;27(30):4212-4214
OBJECTIVE:To compare the efficacy and safety of Sodium hyaluronate versus Carbomer,Polyethylene glycol,To-bramycin and Dexamethasone in the treatment of glaucoma with cataract. METHODS:464 glaucoma patients with cataract were randomly divided into group A(116 cases),group B(116 cases),group C(116 cases)and group D(116 cases). All patients re-ceived intraocular lens implantation;1-1.5 cm to Tramycin and Dexamethasone eye ointment,3-5 times a day. Based on it,group A received 1-2 Sodium hyaluronate eye drops,4 times a day. Group B received 1 Carbomer eye drop,3-5 times a day. Group C re-ceived 1-2 Polyethylene glycol eye drops,3-5 times a day. Group D received Tobramycin and dexamethasone eye ointment,1-1.5 cm every times,1-3 times a day. They treated for 1 month. Clinical efficacy,recovery of visual acuity and ocular surface functions [dry eye symptom score,tear film break-up time(BUT),corneal fluorescein staining(CFS),basal tear secretion(SIt),ocular sur-face disease index(OSDI)] and the incidence of adverse reactions in all groups were observed. RESULTS:The total effective rate sorted,patients with visual acuity higher than 0.6,BUT,OSDI by group A>group B>group C>group D,with significant differenc-es (P<0.05). patients with visual acuity in 0.3-0.6,0.1-0.3 and lower than 0.1,drycye symptom score,CFS,SIt in group A was less than group B,which was less than group C and group D,with significant differences(P<0.05). The incidence of adverse re-actions in group A was lower than group B,C,D,with significant differences(P<0.05),but there was no significant difference in group B,C,D(P>0.05). CONCLUSIONS:Sodium hyaluronate shows superior efficacy and safety to Carbomer,Polyethylene glycol,Tobramycin and Dexamethasone in the treatment of glaucoma with cataract,it can significantly improve visual acuity and ocular surface function.
