OBJECTIVETo assess the clinical value ofprocalcitonin in cirrhotic patients with severe infection by comparing the serum procalcitonin levels in those patients with and without liver cirrhosis when suffering from sepsis.

METHODSA total of 225 septic patients were included in the study,including 91 patients without hepatopathy, 80 patients with cirrhosis, and 54 patients with chronic liver disease. The serum procalcitonin level was measured in all patients and statistically assessed for correlation with relevant clinical biochemistry indicators. The t-test, ANOVA test, Mann-Whitney U test, chi-square test and Spearman's correlation analysis were used for statistical analyses.

RESULTSThe patients with cirrhosis showed significantly lower serum procalcitonin levels (0.84 (0.32-3.44) ng/ml) than the patients with no hepatopathy (2.17 (0.70-9.18) ng/ml) or the patients with chronic liver disease (2.12 (0.33-13.61) ng/ml) (both P less than 0.05); the patients in the no hepatopathy group and the chronic liver disease group showed statistically similar levels of serum procalcitonin (P=0.616). The patients with cirrhosis of Child-Pugh grade C showed significantly higher level of serum procalcitonin (1.25 (0.54-4.61) ng/ml) than those patients with Child-Pugh grade B (0.33 (0.14-1.31) ng/ml; P=0.026), suggesting that patients with Child-Pugh C stage cirrhosis may be more susceptible to gram-negative bacterial infection. In the cirrhosis group,serum procalcitonin level was positively correlated with white blood cell (WBC) count (r=0.312) and percentage of neutrophils (N%) (r=0.228) (both P less than 0.05). Correlation analysis of the no hepatopathy group and the chronic liver disease group showed no correlation between serum procalcitonin level and either WBC or N%.

CONCLUSIONUnder the sepsis condition, cirrhotic patients have lower serum procalcitonin level than patients without cirrhosis, and the serum procalcitonin level is positively correlated with WBC count and N%.

OBJECTIVETo compare the effects of Bushen Jiedu Recipe (BJR) and Jianpi Jiedu Recipe (JJR) containing plasma on dendritic cells (DCs) of chronic hepatitis B virus (HBV) infection patients under different immune states.

METHODSRecruited were 36 chronic HBV infection outpatients from First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from April 2010 to January 2011. They were assigned to the immune tolerance group (18 cases) and the immune clearance group (18 cases).Another 10 healthy subjects were recruited as the healthy control group. Their anticoagulated peripheral venous blood was respectively collected. The peripheral blood mononuclear cells (PBMCs) were isolated and further extracted for incubating DCs. The DCs were intervened by BJR and JJR containing plasma. The morphology of DCs was identified. The expressions of CD1alpha, CD80, CD86, and HLA-DR were detected. The level of interferon-alpha (IFN-alpha) in the supernatant was observed by ELISA.

RESULTSThe CD80 expression level was lower in the immune clear group than in the healthy control group before intervention (P < 0.05). The expression levels of CD80, CD86, and HLA-DR were lower in the immune tolerance group than in the healthy control group before intervention (P < 0.05).The IFN-alpha expression level was lower in the immune tolerance group and the immune clearance group than in the healthy control group before intervention (P < 0.05). The expression levels of CD80, HLA-DR, and IFN-alpha were lower in the immune tolerance group than in the immune clearance group before intervention (P < 0.05). Compared with the same group before intervention, the CD80 expression significantly increased in each treatment group (P < 0.05). After intervention the expression levels of CD80 and HLA-DR were higher in the immune tolerance group than in the immune clearance group in the same time phase, and the CD86 expression level was higher in the BJR group than in the immune clearance group in the same time phase, showing statistical difference (P < 0.05).

CONCLUSIONSThe middle dose BJR and the small dose JJR both could promote the recovery of DCs in chronic HBV infection patients. Besides, BJR showed more prominent effects on the function of DCs in chronic HBV infection patients in the immune tolerance stage.

OBJECTIVETo study the prevalence of hepatitis B virus (HBV) genotype in 5 cities of Fujian province and the clinical implications of distinct genotypes in HBV-related liver diseases.

METHODSHBV genotype was determined by the restriction fragment length polymorphism analysis in patients with chronic HBV infection in 5 cities of Fujian province. The relationship between HBV genotype and its clinical implications was studied by multinomal logistic regression and correspondence analysis.

RESULTSOf the 431 HBV DNA positive patients detected by PCR, 275 (63.8%) belonged to HBV genotype B, 100 (23.2%) to genotype C, 51 (11.8%) to genotype D and D-mixed genotype. Genotype A, E and F were not found. Multinomal logistic regression showed that genotype B was more prevalent in Quanzhou and Sanming cities than in Fuzhou (P = 0.002, P = 0.006), and genotype B appeared significantly more common in asymptomatic carriers (ASC), chronic hepatitis B (CHB) and severe hepatitis (SH). Genotype C was most prevalent in patients with liver cirrhosis (LC) (47.0%) than in those with ASC (14.5%) and SH (14.7%) (P = 0.009, P < 0.001). The positive rate of hepatitis B e antigen was higher in patients with genotype C than in those with genotype B and genotype D (56.0% vs. 52.4%, P = 0.008, and 56.0% vs. 30.8%, P = 0.051, respectively). By correspondence analysis, genotype D and D-mixed genotype seemed to be correlated with hepatocellular carcinoma (HCC).

CONCLUSIONS(1) The major popular genotypes of HBV were B, C and D in Fujian. (2) Data of our study suggested that the geographic distribution of genotype B and C might be different in some cities of Fujian. (3) Genotype B might have a tendency to lead to SH in younger patients with chronic hepatitis B and the development of LC might be associated with genotype C among the elder patients. (4) Genotype D appeared to associate with development of HCC, which called for further study to confirm.

BACKGROUNDThe surgical management of the absence of the vagina is a complex problem and constitutes a significant technical challenge. As the laparoscopy has been an important tool for the treatment of uterovaginal anomalies, we evaluated the feasibility of laparoscopic vaginoplasty using an ileal segment retrospectively.

METHODSTotally 86 patients who underwent laparoscopic vaginoplasty using an ileal segment in Beijing Anzhen Hospital during February 2004 to July 2007 were enrolled in this study. Of the 86 patients, 70 (81.4%) underwent primary operations and 16 (18.6%) secondary operations. Nineteen (22.1%) patients underwent total laparoscopic vaginoplasty and 67 (77.9%) patients underwent laparoscope-assisted vaginoplasty. The operation time, cost of hospitalization, and hospital duration were compared between the two laparoscopic groups. The Student's t test and the Mann-Whitney test were used to examine the differences.

RESULTSAll the surgeries were successfully completed with no any intraoperative complication. There were three major surgical complications in the postoperative period: one case of intra-abdominal hemorrhage, one case of meatal stenosis, and one case of intestinal obstruction. The mean follow-up period of this series was 18 months. Seventy-eight patients were satisfied with their sexual lives after the surgeries except 5 women complaining of vaginal stenosis and 3 with no sexual partner during the follow-up. Significant differences were obtained between total laparoscopic and laparoscope-assisted vaginoplasty groups, such as the operation time, cost of hospitalization, and hospital duration (P < 0.01). There were no significant differences in sexual function between the two groups.

CONCLUSIONSThe laparoscopic vaginoplasty using an ileal segment is satisfactory for cosmetic, functional, and anatomic results. Vaginoplasty with an ileal segment, performed by either total laparoscopic or laparoscope-assisted techniques, has a high success rate for a functional vagina.

OBJECTIVETo explore the "hemi-clamshell" approach to the resection of the apical chest tumors, and to evaluate its advantages of operative safety and completeness.

METHODSWe conducted a retrospective review of the records of 27 patients undergoing resection of the primary apical chest tumors from January 1995 to January 2001. Tumor type included NSCLC, sarcoma, neurofibromatosis, esophageal carcinoma. Data collected included clinical presentation, tumor type and involvement, type of resection, complication, and survival.

RESULTSA clinical operation for gross-total resection of tumors and invaded structures was performed on six patients by means of a successful anterior approach. Among other 21 patients on whom a clinical operation was performed by posterior approach, only 13 patients obtained gross-total resection. There were significant difference between the two groups (P < 0.01). The mean duration for follow-up was 29 months, and the overall median survival was 21 months. Median survival in patients undergoing gross-total resection was 29 months, and this is significantly better than in incomplete resection group (P < 0.01).

CONCLUSIONSThe anterior "hemi-clamshell" approach is a successful technique for the exposure and resection of these tumors and invaded structures. Release of symptoms and long-term survival is acceptable if complete resection can be performed.

BACKGROUNDOsteogenesis imperfecta (OI) is a rare bone disease and its effective treatment is relatively deficient. We tried to assess the effects of new bisphosphonate, ibandronate on children with OI.

METHODSIn this open-label, prospective, controlled study, 30 children with OI were enrolled. They received either infusions of ibandronate (2 mg) in every three months or oral calcitriol 0.25 µg daily for 24 months. All patients took 500 mg calcium plus 200 U vitamin D daily together. The endpoints were the change of annual new fracture rate (observed by case history and X ray films of spine), bone mineral density (BMD, measured by dual energy X-ray absortiometry), serum concentration of carboxy-telopeptide cross-links of type I collagen (CTX, bone resorption marker) and alkaline phosphatase (ALP, bone formation marker) during the follow-up.

RESULTSAfter the cyclic infusions of ibandronate, the annual new fracture rate was significantly decreased from 1.9 to 0.13 time, obviously lower than that of calcitriol group, which decreased from 1.8 to 1.0 time after the treatment (P < 0.001). The significant increase of BMD at the lumbar spine, femoral neck, trochanter, total hip was found in the group of ibandronate by 59.0%, 42.0%, 47.5% and 36.6% in time dependent manner (compared with the baseline, P < 0.001). The increase of BMD in ibandronate group was greater than that of calcitriol group (P < 0.001). The concentrations of ALP and CTX were obviously decreased in ibandronate group, and the reduction of CTX was more significant than that of ALP (P < 0.001). The tolerance of the children to ibandronate was quite well. Mild fever and muscle pain were found in 9 cases within 1 - 3 days after the first infusion of ibandronate, which could relieve after 1 - 2 days without special management.

CONCLUSIONSThe benefits of cyclic infusions of ibandronate to children with OI are significant because ibandronate could significantly reduce annual bone fracture rate, increase lumbar and hip BMD, preserve vertebral morphometry of patients through inhibition of bone resorption.

This study was purposed to evaluate the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on hematopoietic reconstruction and survival in beagles exposed to mixed fission neutron and γ-ray. 13 beagles were unilaterally exposed to single dose of 2.3 Gy 90% neutrons. The experiments were divided into 3 groups: irradiation control group (no any treatment, n = 4), supportive care group (n = 5) and rhG-CSF plus supportive care group (n = 4, abbreviated as rhG-CSF group) in which the beagles were subcutaneously injected with 200 µg/kg of rhG-CSF early at half an hour and 24 hours post-irradiation respectively. The results showed that 2.3 Gy 90% neutron irradiation induced a severe acute radiation sickness of bone marrow type. The administration of rhG-CSF increased the survival rate from 60% in supportive care group to 100%. Twice injection of rhG-CSF in the first 24 hours reduced duration of neutropenia, enhanced neutrophil nadir and promoted neutrophil recovery when compared with control cohort administered clinical support. The number of colony-forming cells (CFU-GM, CFU-E, and BFU-E) in peripheral blood of rhG-CSF treated canines increased 2-to 5-fold relative to those of the supportive care group on day 3. All canines treated with rhG-CSF achieved hematopoietic reconstruction as evidenced by the pathological section of sternum while severe shortage of hemopoietic cells remained in the cohorts given supportive care alone. It is concluded that the combination of supportive care and high-dose rhG-CSF can accelerate hematopoietic recovery and enhance survival of dogs exposed to 2.3 Gy mixed neutron and gamma ray.

Objective: To investigate the safety and efficacy of pulmonary vein deployment technique for percutaneous closure of atrial septal defects (ASD) solely under echocardiography guidance. Methods: A total of 38 ASD patients received pulmonary vein deployment in our hospital from 2012-10 to 2016-09 since the conventional method could not deliver the occluder to correct place. The patients were with the mean age at (16.0±15.6) years, body weight at (37.2±22.9) kg and ASD diameter at (17.1±4.2) mm. Operative effect was assessed by echocardiography. Follow-up study was conducted at 1, 3, 6, 12 months post-operation and at each year thereafter. Results: 37 patients were successfully finished pulmonary vein deployment for percutaneous closure of ASD solely under echocardiography guidance. One patient was successfully treated by a controlled steerable sheath. The mean operative time was (25.2±5.1) min and mean diameter of ASD occluder was (22.9±5.6) mm. 2 patients had trivial residual shunt at the early post-operative stage. No peripheral vascular injury, pulmonary vein and cardiac perforation occurred. All 38 patients were recovered and discharged. The average in-hospital time was (2.9±0.7) days. The patients were followed-up for (23.9±15.4) months, without complications of residual shunt, pericardial effusion, aortic regurgitation and pulmonary vein stenosis. Conclusion: Pulmonary vein deployment technique for percutaneous closure of ASD solely under echocardiography guidance was safe and effective; it can avoid radiation damage and provided a simple and practical method for ASD patients who failed to conventional method under echocardiography guidance.
