[Objective] To investigate the value of HBV-M and HBV DNA of newborns born to HBsAg-positive mother, which were tested before combined immunization of hepatitis B. [Method] A total of 420 infants born to HBsAg-positive mothers delivered in Obstetric Department of the Third Affiliated Hospital of Sun Yat-Sen University from June 2006 to February 2008 were followed up at least 6 months and rechecked HBV-M to confirm the diagnosis of HBV intrauterine infection, which included 33 HBsAg or HBV DNA positive newborn babies and 6 newborns with both HBsAg seropositive and HBV DNA seropositive. [Result] HBV intrauterine infection rate was 0.95%. Using newborn both HBsAg positive and HBV DNA positive as diagnostic criterion to diagnose HBV intrauterine infection, the positive likelihood ratio was 208.3, while using newborn HBsAg positive or HBV DNA positive as diagnostic criterion, it was 14.3. [Conclusion] Newborn both HBsAg positive and HBV DNA positive obtained before combined immunization of hepatitis B may predict HBV intrauterine infection, and it may play as a clinical index of preliminary diagnosis of HBV intrauterine infection.

Objective To investigate the clinical characteristics of alcoholic severe acute pancreatitis (SAP). Methods Clinical data of 166 cases of SAP in Fujian Provincial Hospital from January 2001 to December 2008 were collected and analyzed retrospectively. Cases were divided into alcoholic SAP group (43cases) and control group ( 123 cases) depending on deoholic intake volue whithin 12～48 hours. Age, gender,CT scores, APACHE Ⅱ score, serum glucose, serum triglyceride (TG), serum calcium, serum albumin,morbidity, later infection rate and mortality rate of the two groups were compared. Results There was no significant difference in terms of age, but the proportion of male in alcoholic SAP group (39/43) was higher than that in control group (58/123, P<0.01 ). CT score, serum glucose and calcium were not significantly different between the two groups. The APACHEⅡ score and serum TG in alcoholic SAP group [19.16±5.38,(5.06±4.03)mmol/L] were significantly higher than those in control group [16.02±5.09, (3.12±2.95)mmol/L]. The albumenjolevel in alcoholic SAP group (25.23±7.12)g/L) was lower than that in control group [(30.68±8.35 ) g/L, P<0.01]. The incidences of ARDS and upper gastroenterologic bleeding were not significantly different between the two groups. But the incidences of acute kidney failure (44.2%), liver failure (41.9%), heart failure (37.2%), shock (39.5%), infection (27.9%) and mortality (30.2%) in alcoholic SAP were significantly higher than those in control group (26.0%,30.9%, 20.3%, 16.3%,16.3%, 7.3%, P<0.05 or<0.01). Conclusions Males predominates alcoholic SAP patients with high mortality and morbidity. Alcohol abstinence is effective to prevent alcoholic SAP ocurrence.

BACKGROUND:Interlocking intramedul ary nail complications contain nail bent or broken, exit, re-fracture at spiketail or nail hole. Thus, our team designs a novel intramedul ary control ed dynamic nail.
OBJECTIVE:To evaluate the rationality and safety of intramedul ary control ed dynamic nail design and strength, and to give rational proposal for its clinical application.
METHODThe three-dimensional finite element models of composite femur, transverse fractures of the femoral shaft were constructed with intramedul ary control ed dynamic nailing. The stress and strain were detected under vertical loads and gait cycle.
RESULTS AND CONCLUSION:The maximum stress of the intact femur under the compression load was at femoral neck and the medial and lateral aspects of the femoral shaft;while the stresses of fractured femur were at the interface between screw and screw hole. In gait cycle, in case of intact bone, large stresses were found in the distal 1/2 of anteriomedialis of femoral shaft;while the stress distribution in fractured femur was similar with the 
former. Intramedul ary control ed dynamic nailing has the ability of generating compression between fragments. These suggest that intramedul ary control ed dynamic nailing is rational and good at design and biomechanical properties.

OBJECTIVE: To explore the effection of the pulmonary function of patients of chronic rhinosinusitis (CRS) with asthma which treated with endoscopic sinus surgery (ESS) based comprehensive treatment. METHOD: There were 50 cases of chronic rhinosinusitis with asthma whom met the study criteria. 35 cases enrolled in the tri al group, which treated with endoscopic sinus surgery, and routine perioperative tratment. Another 15 cases as control group which underwent conservative treatment. Both groups underwent the rule treatment of asthma. The main monitoring indexes, which included visual analogue scale (VAS) score, endoscopic Lund-Kennedy score, control of asthma symptoms, the pulmonary function which involved forced expiratory volume in first second (FEV1), forced vital capacity (FVC), the ratio of forced expiratory volume in first second and forced vital capacity (FEV1/FVC) and peak expiratory flow (PEF), were measured in the patients of each groups before surgery, follow-up for 1 year and 3-year. RESULT: Our study found that the VAS score of CRS with asthma was significantly negatively correlated with FEV1 and PEF (P < 0.05), endoscopic Lund-Kennedy score was significantly negatively correlated with PEF (P < 0.05); After the trial group underwent ESS based comprehensive treatment, the improvement of VAS score and endoscopic Lund-Kennedy score of postoperative compared with preoperative and the same period in the control group were significantly (P < 0.05). The difference of the postoperative asthma control rate of trial group after 1 year and after 3 years, respectively, compared with the same period control group were statistically significant (P < 0.05). The preoperative FEV1, FVC, FEV1/FVC and PEF of trial group compared with preoperative were significantly (P < 0.05). Even the difference of them compared with the same period control group were significantly (P < 0.05), except the FVC in the follow-up 3 years (P = 0.088). CONCLUSION The CRS may aggravate asthma symptoms and affect negatively the pulmonary function, and poor asthma control or aggravate may exacerbate the CRS in the course of CRS with asthma patient. With ESS based on combined therapy, it can improve the condition of CRS significantly and improve the control of asthma symptoms and pulmonary function else.
