Objective To evaluate the value of serum procalcitonin (PCT) in antibiotics used for the treatment of acute exacerbation of asthma. Method From February 2007 to July 2009, a total of 158 patients with asthma were randomly (random number) assigned to PCT group ( n = 77) or to control group ( n = 81 ). The PCT levels of all patients were measured. On the bases of routine treatment, the employment of antibiotics in control group was determined by the guidebook, and patients in the PCT group were treated with antibiotics guided by the levels of serum PCT. The antibiotics treatment was employed as PCT level ＞0.25 ng/mL, and was not employed as PCT level ＜ 0.25 ng/mL. The rates of antibioties employment were observed. Results The rate of antibiotics employment in PCT group (45.4%) was lower than that of the control group (77.8%) (x2 = 17.15,P =0.000). Conclusions PCT could be used safely as guidance of antibiotics employment for the treatment of patients with acute exacerbation of asthma, leading to appropriate use of antibiotcs.

Objective To investigate the influence of age on liver histopathological feature of patients infected with chronic hepatitis B. Methods Liver biopsies were performed on 114 patients with chronic hepatitis B. The biochemical tests were measured by routine automated techniques. Serum hepatitis markers including HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc were assayed by using a microparticle enzyme linked immunosorbent assay. HBV-DNA was measured with quantitative polymerase chain reaction assay. The grades of liver necrosis/inflammation and fibrosis were compared between four groups with different age: younger than 20years, 20 ～ 30, 31 ～40, and older than 40 years. Results All 114 patients had liver histological changes with different degree. 75.4 percent (89/114) of cases had 2/over 2 grades of liver necrosis/inflammation, and 47.4 percent (54/114) of cases had 2/over 2 stages of liver fibrosis.There was no significant relation between the level of ALT and age or between the level of ALT and the grades of liver necrosis/inflammation and fibrosis( P ＞0. 05 ). The significant difference in degrees of liver inflammation and fibrosis was found among three age groups ( x2 = 30. 86, P ＜ 0. 01; x2 = 21.17; P ＜0.05 ). The grades of 1 iver inflammation and fibrosis increased with the increased age of the patients. Conclusion These results suggested that age was an independent factor for the disease progression. It was very important to undertake liver biopsy for patients with CHB more than 30 years to reveal the liver histopathological characteristics and guide the treatment.

Objective To investigate the changes of clinical and laboratory manifestations of rheumatic fever (RF) in recent ten years by reviewing the medical data of 315 patients with RF. Methods Three hundred and fifteen in-patients and out-patients with RF during 1985-1995 (group A) and 1997-2007(group B) were selected. Their manifestations were compared. Results Male/female ratio was about 1:2. Carditis and polyarthritis were common manifestations. Compared with group A, the rate of low-grade fever and carditis increased and the rate of heart failure, positive rate of C reaction protein and antistreptolysin O decreased in group B. In group B, 61.4% patients fulfilled the updated Jones diagnostic criteria. 76.2% fulfilled the 2002-2003 WHO criteria. The sensitivity and specificity of peripheral blood lymphocyte procoagulant activity (PCA) for the diagnosis of rheumatic carditis was 79.1% and 71.4% respectively. That of the anti-streptococcal group A polysaccharide (ASP) antibodies was 70.3% and 70% respectively. Five to ten years follow-up clinical data were available for 35 cases since Dec. 1997. The recurrent rate of RF was 62.8%. Only 1/3 cases received regular secondary prevention. Recurrence rate of patients with regular secondary prevention was significantly lower than that of patients without regular secondary prevention. Conclusion Mild earditis has been increasing during last ten years. PCA and ASP are valuable tests for diagnosing rheumatic carditis. More emphasis should be paid to atypical cases, early diagnosis and regular secondary prevention in order to improve prognosis.

Objective To investigate the impact of different kinds of laparoscopic surgery including conventional blunt elimination and modified acute elimination on sex hormone, antral follicle count and ovarian volume of patients with endometriosis (EMs). Methods 100 patients with EMs were chosen from January 2013 to April 2016 and randomly divided into control group (50 patients) with conventional blunt elimination and observation group (50 patients) with modified acute elimination; and the thickness of elimination lesion, the removal rate of ovary cortex, the thickness of ovarian cortex, the level of serum sex hormones, the AFC number of affected side and the volume of ovary before and after operation of the two groups were compared. Results There was no significant difference in the thickness of lesion elimination, the removal rate and removed thickness of ovarian cortical between the two groups (P > 0.05). The thickness of lesion elimination and the thickness of ovarian cortex in middle position of observation group were significantly lower than that in control group (P < 0.05). The thickness of lesion elimination, removed thickness of ovarian cortical and the removal rate of ovary cortex in hilus ovarii in observation group were significantly lower than that in control group (P < 0.05). There was no significant difference in the levels of serum sex hormones before and after treatment between the two groups (P > 0.05). There was no significant difference in the levels of AFC number of affected side before and after treatment (P > 0.05). The levels of AFC number of affected side in hilus ovarii of control group after treatment were significantly lower than that before treatment (P < 0.05). The volume of ovary of both groups after treatment were significantly lower than that before treatment (P < 0.05). The volume of ovary of observation group after treatment were significantly higher than that in control group (P < 0.05). Conclusion Compared with conventional blunt elimination, modified acute elimination in the treatment of patients with EMs can efficiently shorten the operation time, reduce the surgical trauma degree, speed up the recovery process after operation, regulate the level of FSH and AMH and be helpful to protect the ovarian reserve function.
