Chinese Journal of Primary Medicine and Pharmacy 2012;19(16):2437-2438
ObjectiveTo study the relationship between serum-asicites albumin gradient(SAAG) and the portal hypertensive ascites in order to appreciate the value of SAAG on the prediction of esophageal-gastric fundus variceal bleeding.Methods34 patients with cirrhotic ascites were examined with endoscopy.The patients were classified as high-gradient group and low-gradient group by the SAAG value of 11g/L.The relationship between SAAG and esophageal-gastric fundus varices was studied by Pearson correlation analyasis.Among the 34 patients studied,10 patients had esophageal-gastric fundus variceal bleeding and 24 patients had no esophageal-gastric fundus variceal bleeding.ResultsIn the 30 patients classified as high-gradient group,22 patients had esophageal-gastric fundus variceas.In the 4 patients classified as low-gradient group,no patient had esophageal-gastric fundus variceas.The results showed the direct correlation between the level of SAAG and the degree of esophageal-gastric fundus variceas ( r =0.81,P <0.01 ).The mean level of SAAG in bleeding group,consisting 10 patients,was (24.18 ±7.36) g/L.The mean level of SAAG in non-bleeding group,consisting 24 patients,was ( 18.19 ± 6.18)g/L.The results showed sig nificant difference between the bleeding group and non-bleeding group(P <0.05).ConclusionThere is correlation between the level of SAAG and the portal venous pressure.The level of SAAG is valueable on the prediction of esophageal-gastric fundus variceal bleeding.

Objective To investigate the association between apolipoprotein E (apoE) genotype polymorphism and cerebral palsy (CP) in Han Chinese children. Methods Two hundred and forty Han Chinese children were selected, including 120 children with cerebral palsy (CP group) and 120 normal children (control group).Polymerase chain reaction-restricted fragment length polymorphism analysis was used to determine the genotype and alleles of apoE genotype in the two groups. Results The genotype distributions of apoE in the two groups were consistent with the existence of a Hardy-Weinberg equilibrium. There were significant differences in the distributions of allelic frequency and apoE genotype between the two groups. Carrying the ε4 allele was related to cerebral palsy, and the overall risk for cerebral palsy was elevated about 5.5-fold among children carrying the ε4 allele.Conclusions There is an association between apoE genotype and cerebral palsy, and apoE's ε4 allele is the associated risk factor.

Objective To analyze the incidence of hospital-acquired infection and the distribution of pathogens through data from the hospital infection surveillance networks in Shandong. Methods A meta-analysis was made of the data submitted by the hospitals involved in the provincial surveillance networks from August 2001 to July 2004. Results The surveillance data involved 1 776 030 hospitalized patients, of whom 43 355 had a hospital-acquired infection, the incidence of hospital-acquired infection being 2.44‰. Respiratory-tract infections were most frequent, followed by gastroenteric-tract infections, urinary-tract infections and surgical-site infections. A total of 6 251 strains of pathogens were isolated, the most commonly identified pathogens being Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Candida albicans and Staphylococcus epidermidis. Conclusion It is imperative to reinforce the sterilization of air and medical instruments, strictly abide by aseptic manipulation, and promote the rational use of antimicrobials. Hospital infection surveillance ought to be conducted by the combined method of prevalence surveys and the targeted surveillance of key sectors.

Objective To study if tumor retraction assessed by endiscopic uhrasonography (EUS) during radiotherapy has prognostic value in esophageal carcinoma, which may further predict the radiosensi-tivity. Methods The maximal tumor thickness was measured by EUS before radiotherapy and at 40 Gy in patients with esophaged carcinoma. Response was defined as at least 50% reduction in tumor thickness. Re-suits A total of 51 patients were included. The median follow-up time was 28.5 months. The median sur-vival time was 24.3 months. The treatment was radiotherapy alone, concurrent chemoradiotherapy and pre-operative treatment in 35, 10 and 6 patients, respectively. Tumor response was assessed by EUS in 18 pa-tients (34%). The 2-year overall survival (OS) and progression-free survival (PFS) were 69% and 59% for responders, comparing with 37% and 29% for non-responders (χ~2= 5.78, P = 0.016 and χ~2= 3.97, P =0.046, respectively). In radiotherapy alone group, the 2-year OS and PFS were significantly higher in responders (n = 11) comparing with non-responders (n =24)(60% vs 44% ,χ~2 =5.84,P =0.016 and 20% vs 10% ,χ~2 =4.20, P =0. 040). In preoperative radio (chemo) therapy group (n =6), pathological-ly complete response, partial response and minimal response were observed in 4, 1 and 1 patients, respec-tively. EUS detected tumor response in 4 of 5 (80%) patients with tumor regression, and non-response in 1 of 1 patient without tumor regression. Conclusions The prognosis is better in patients with esophageal car-cinoma responding to neoadjuvant treatment identified by EUS than that of non-responders.

Objective To study the effect of acute hypervolemic hemodilution on expression of serum chemokine interferon-inducible protein 10 in patients undergoing total hip replacement.Methods Twenty ASA Ⅰ or Ⅱ patients undergoing elective total hip replacement were randomly divided into 2 groups (n=10 each):HES group and LR group.The patients in HES group received 6% HES 20 ml/kg in rate of 30 ml/(kg·h) after anesthesia.The patients in LR group received Ringer's solution 20 ml/kg in rate of 30 ml(kg·h) after anesthesia.The blood loss,blood transfusion and the time of operation were recorded.Venous blood samples were taken before anesthesia (T0),at the begining of operation (T1),30 min after operation (T2),and at the end of operation (T3),in determination of serum chemokine interferon-inducible protein 10.Results The blood loss and the blood transfusion in HES group were (560±90)ml and (200±100) ml,those were significantly lower than that in LR group[(810±110)ml and (600±200)ml].The IP-10 concentrations were significantly increased at T2~T3 as compared to baseline value at T0 in both groups,but were higher in LP group[(77.3±13.8) ng/L and (89.9±15.1) ng/L]than those in HES group [(62.8±13.6) ng/L and (65.4±10.2) ng/L,P<0.05].Conclusions Acute hypervolemic hemodilution can abate blood loss and blood transfusion during total hip replacement operation.Preoprative infusion with hydroxyethyl starch can attenuate the immunological depression during operation and anesthesia.

Objective To study the effect of acute hypervolemic hemodilution on expression of plasma bac-tericidaL/permeability-increasing protein (BPI) in patients undergoing total hip replacement. Methods Twenty ASA Ⅰ-Ⅱ patients undergoing elective total hip replacement were randomly divided into two groups (n=10 for thesia. The blood loss,blood transfusion and the time of operation were recorded. Venous blood samples were taken before anesthesia (T0) ,at the begining of operation (T1) ,30 min after operation (T2) ,and at the end of operation (T3) for determination of plasma bactericidal/permeability-increasing protein. Results The blood loss and the blood transfusion in HES group were significantly lower than that of LR group[blood loss: (560±90)ml vs (810±110) ml and blood transfusion: (200±100) ml vs (600±200) ml,t=5.562 and 5.657,P<0.001]. The plasma BPI concentrations in HES group were significantly increased at T2~T3 as compared to baseline value at T0 [(8.9±1.6)μg/L,(13.4±1.2)μg/L and (4.9±1.2)μg/L,P<0.05]. The plasma BPI concentrations in LR group were significantly increased at T2~T3 as compared to baseline value at T0 [(7.3±1.2)μg/L,(9.9±0.8) μg/L and (5.0±1.1)μg/L,P<0.05],but were lower than those in HES group (t=2.530 and 7.674,P=0.021 and 0.001 ). Conclusion Acute hypervolemic hemodilution with 200/0.5 hydroxyethyl starch can reduce blood transfusion during total hip replacement operation and also can increase the BPI level which would beneficial for the immunological function.
