Objective: To supply a scientific basis for standardizing the normal reference value of forced vital capacity (FVC) of Chinese younger women. Methods: We studied the relationship between the normal reference value of 21 767 samples of FVC of younger women and eight geographical factors in 157 areas in China. Results: It was found that the correlation between geographical factors and the normal reference value of FVC of younger women was quite significant (F = 5.884, P = 0.000). By adopting the method of mathematical regression analysis, one regression equation was inferred: Y = 3.146+0.00006919X1+0.01315X4-0.006966X6+0. 09524X8±0.254. In the above equation, Y is the normal reference value of younger women' FVC (L); X1 is the altitude (m); X4 is the annual mean air temperature (°C); X6 is the annual mean relative humidity (%); X8 is the annual mean wind speed (m/s); 0.254 is the value of the residual standard deviation. Conclusion: If geographical values are obtained in a certain area, the normal reference value of FVC of younger women in this area can be obtained by using the regression equation. Furthermore, according to the geographical factors, China can be divided into eight regions: Northeast China Region, North China Region, Shanxi-Shaanxi-Inner Mongolia Region, middle and lower reaches of the Yangzte River Region, Southeast China Region, Northwest China Region, Southwest China Region, and Qinghai-Tibet Plateau Region.

Objective To evaluate the usefulness of ultrasound during the operation of 125 I permanent brachytherapy for pancreas carcinoma.Methods According to the mass size,the total radiation dosage and the amount of radioactive seeds were calculated before operation.Then all needles were inserted evenly in the mass and radioactive seeds were implanted through the needles under ultrasonic guidance during the operation. At the end of operation,ultrasonography and/or abdominal radiography were applied to examine the distribution of seeds and to find if any place was left out. Results Thirteen patients were operated on successfully and the mass was displayed clearly with ultrasonography. Under the guidance of ultrasound,needles were exactly inserted in the mass and the whole process of implantment was easily observed. Locations were proved exactly by ultrasonography and abdominal radiography after operation. Conclusions Ultrasound has some important values in this procedure,such as precise orientation,real-time monitoring,follow-up evaluation,etc. Application of ultrasonography has the broad prospect in this field.

A research evaluation system was preliminarily established in a level-two general hospital.Conclusion The evaluation system is simple and practicable,and can reflect the main aspects of research in the leveltwo general hospitals.

Objective To study the effect of preoperative blood pressure control on postoperative cardiovascular events in patients with hypertension and gastrointestinal surgery. Methods A total of 238 hypertensive patients who underwent gastrointestinal surgery were selected and divided into control group (n =118)and non-control group (n =120)according to thehypotensor treatment.During the operation,the same anesthetic regimen was used.The use of vasoactive drugs was recorded during anesthesia.Bladder chalone C (Cys C)and cardiac troponin T (cTnT)were de-tected in blood before and after the operation,and so were N-terminal B type natriuretic peptide (NT-proBNP)level on the 1st and 5th day after the operation.The postoperative hospitalization time,fol-low-up of cardiovascular events 28 and 90 days after discharge were recorded.Results Compared with the non-control group,the total dosage of ephedrine in the control group was significantly re-duced [(3.41±1.04)mg vs (7.46 ± 3.29)mg,P <0.05 ],total dose of phenylephrinewas signifi-cantly reduced [(0.17±0.10)mg vs (0.46 ±0.16)mg,P <0.05],postoperative hospital stay was significantly shorter [(5.92±1.15)d vs (9.65±1.61)d,P <0.05],NT-proBNP level in the control group on the 1st day after the operation [(108.00 ± 47.11 )pg/L vs (250.38 ± 62.92 )pg/L,P <0.01]and 5 days after the operation [(62.07 ±25.31)pg/L vs (199.02 ± 60.32)pg/L,P <0.01 ] was obviously reduced.There was no statistical difference in Cys C andcTnT between the two group-safter operation.The incidence of cardiovascular adverse events in the control group was significantly lower than that in the non-control group (28 d:13.6% vs 62.7%,90 d:23.3% vs 23.3%,P <0.05).Conclusion Strict control of preoperative blood pressure control in patients with hypertension can significantly reduce the incidence of cardiovascular events.

Objective:To discuss the relationship between the geographic environment and blood urea nitrogen(BUN) reference values of the healthy people,and to explore the distributional rule of BUN reference values of the healthy people,and to provide the scientific foundation for establishing the BUN reference value standards of different areas.Methods:A total of 23 geographic factors and 33 521 BUN reference values of healthy adults measured by 403 medical facilities from 23 provinces,4 municipalities and 5 autonomous regions were collected.The spatial autocorrelation analysis was used to determine the spatial autocorrelation of the sample data;the correlation analysis was used to detect the factors which correlated significantly with the BUN reference values;the multiple linear regression,principle component analysis and ridge regression analysis were respectively used to construct the predicted models;the paired-sample t test was used to choose the optimal model;the distribution map of BUN reference values was built by geostatistic analysis.Results:There were 5 geographic factors,latitude(X2),altitude(X3),annual mean temperature(X5),annual mean relative humidity(X6) and annual precipitation(X7),correlated significantly with the BUN reference values.The regression equation of optimal model was Y^=5.112+0.000 127 1X2+0.000 094 61X3-0.000 140 5X5-0.000 136 8X6-0.000 139 1X7±0.531 0;the distribution map of predicted values of the BUN reference values was obtained.Conclusion:The overall trend of BUN reference values is low in the east and high in the west.The BUN reference value is negatively associated with the altitude.If the geographic data of a certain region could be obtained,the BUN reference value of this region will be predicted.

Abstract?AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.?METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.?RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P < 0. 05 ). The average lOP after treatment of 1d in the two groups were not statistically different (P>0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P<0. 05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference (P<0. 05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break- up time, was significantly superior to expose conjunctiva suture group (P<0. 05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group (P<0. 05).? CONCLUSlON: Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.
