Urinary tract infection (UTI)is a commonly encountered disease during routine clinical care. In the mean time, it is also a commonly encountered hospital acquired infection. UTI possesses various clinical symptoms, and usually the symptoms are atypical. The detection of leukocyturia and bacteriuria is an essential index for screening and confirmatory diagnosis of UTI. This article summarized the pathogenesis of UTI, diagnostic criteria, clinical significance and application evaluation of detection of the WBC and bacteria in urine.

Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.

Objective:To evaluate the application status and change trends of insulin and its analogs in Nanjing area during 2011 to 2013. Methods:The varieties, sales amount and DDDs of insulin and its analogs in 43 hospitals of Nanjing during 2011 to 2013 were analyzed. Results:The use of insulin and its analogs was increased year by year from 2011 to 2013 with the average annual growth rate of 16%. Glargine, pre-mixed insulin 30R, aspart 30, human insulin and aspart ranked the top five in the sum of money with the proportion above 80%. Pre-mixed insulin 30R, aspart 30, glargine, human insulin and common insulin ranked the top 5 in DDDs. Conclusion:The application of insulin and its analogs is wide in clinics, and the usage and sum of money both show rapid growth trend.

Autonomic nervous system(ANS) activity plays an important role in the pathogenesis of cardiovascular disease,including organic cardiovascular disease(such as hypertension,coronary artery disease,etc) and functional cardiovascular disease (such as vasovagal syncope,postural orthostatic tachycardia syndrome,etc).Many methods was used to evaluate ANS function.Heart rate variability is a widely accepted method to assess cardiac autonomic nerve function.Autonomic nervous affected cardiac action potential and let electrocardiogram changes.Through the sympathetic and parasympathetic neurotransmitters which acting on the corresponding receptors.Electrocardiogram changes reflects autonomic nervous function.Present researches suggest that electrocardiogram has an important significance in the evaluation of autonomic nerve function in functional cardiovascular disease.

Objective:To observe the therapeutic effect of the method of clearing lung and descending stomach and its mechanism on gastroesophageal reflux cough(GERC).Method:125 cases of GERC were divided randomly into the treatment group(n=65) treated by the therapy of clearing lung and descending stomach(with a self-designed decoction) and the control group(n=60) treated with Omeprazole and Domperidone,and they were all treated for 12 weeks.Results:The total effective rate was 92.3% in the treatment group and 78.3% in the control group,with a significant difference between the two groups(P

Objective To discuss the surgical skills and clinical value of laparoscopic splenectomy with a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen.Methods A total of 88 patients with hypersplenism secondary to liver cirrhosis who underwent laparoscopic splenectomy in our department from September 2015 to September 2016 were selected into this study.And these patients were divided into two groups based on whether to take the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The control group included 40 cases who underwent the traditonal laparoscopic splenectomy,while the observation group included 48 cases who took the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The clinical data were collected retrospectively by medical clinical records review.Results There was no mortality occurred in this study.The blood loss of the observation group was (247.50±135.89)mL,which was obviously lower than (361.75±144.43)mL of the control group,and the difference was statistically significant (P<0.05).The operation time of the two groups were (194.69±47.99)min and (232.75±45.26)min respectively,and the difference was statistically significant (P<0.05).No significant difference was found in terms of rate of conversion to laparotomy,rate of intraoperative blood transfusion,postoperative hospital stay and complications (P>0.05).Conclusion It is very crucial for a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen to establish a tunnel behind the splenic hilum in laparoscopic splenectomy.It is safe and feasible to perform a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The technique is generalized in clinics,especially for freshmen.

The researches on attention provide a promising framework for studying bipolar disorder pathophysiology and treatment.Previous findings have shown the negative attention bias maybe a risk factor for bipolar disorder.The current review discusses this issue in several aspects,including attention bias toward emotional information in bipolar disorder is state or trait,and whether shows mood-congruent bias;the character of attention bias in the different episodes of bipolar disorder.The article also puts forward an intervention of attention bias modification for treating bipolar disorder.

Sera were collccted from mice immunized separately with schizonts, merozoitcs or different parasite stages, or from mice which had been recovered from Plasmodium yoelii yoelii infection. The effect of protection of cach serum against P. y. infection was assayed by passivc transfer technique. It was shown that only sera collected from mice which either had been trcated with chloroquine or had been naturally recovcred from P. y. infections can transfer certain dcgree of resistance to normal mice. The cffectivc sera delayed the appearance and the peak of parasitemia, and prolonged the survival time of the challenged mice. After these sera were fractionatcd by 50%(NH4)2SO4 precipitation, the prccipitated fraction showed similar degree of protection as the non-fractionated sera. Chloroquine-treated serum was shown to be able to inhibit the invasion of new erythrocytes by marozoite in vitro. 35S-methionine-labelcd antigens were precipitated by protective or non-protective sera and the bands were compared on SDS-PAGE and autoradiogram. Since thc antigcn bands of 245, 210, 190, 156 and 130 KD can only bc precipitated by protective sera but not by non-protectivc sera, it is possible that the protection of chloroquine-treated serum is induced by the specific antibodies against the above antigens.

The configuration of the air cleaner and operating principle of high-voltage static electrical field (HVEF) are introduced. The primary bactericidal mechanism and broad-spectrum effect are also mentioned.

Abdominal drainage is the most common technique applied in the abdominal surgery. According to the aim of drainage, it can be divided into curative drainage and preventive drainage, but there is no obvious difference between the 2 drainages. Abdominal drainage is not necessary after parenchymal viscera operation, but necessary after spleenectomy in preventing infection. For cavity viscera operation, abdominal drainage is applied according to the infectious condition, but scholars at home and abroad have different opinions on this point. Surgeons should pay attention to the placement of the drainage tube in patients who received preventive drainage.
