OBJECTIVE:To understand the prophylactic antibiotics use in general surgeries performed in the hospital where the authors work.METHODS:500copies of discharge record of common surgical cases written between Jul.2005and Feb.2006were checked randomly,and the questionnaires about the general data and medication of the patients were filled out.Then the collected data were analyzed statistically.RESULTS:The prophylactic drug use rate in TypeⅠincision operations reached up to98.8%,of which58.5%cases lacked clear indications of medication.The high rate of prophylactic drug use,improper time of drug use,and the prolonged continuous drug use were among the problems that existed in TypeⅠand TypeⅡincision operation.CONCLUSION:There remain many problems in the use of prophylactic antibiotics in the general surgeries performed in our hospital,which requires the strengthening of standardized administration of prophylactic antibiotic use.

AIM:To asses the presence and clinical significance of metallothionein,(MT) in primary invasive ductal carcinoma of the breast. METHOD: 96 cases of routinely fixed and paraffin-embedded primary breast carcinomas were investigated with the labelled avidin biotin immunohistochemical method. RESULTS: The positive staining for MT observed was 52.1% (50/96). In most cases both nuclear and cytoplasmic staining was seen. A statistically association was found between MT positive staining and nuclear grade( P

ObjectiveTo compare the liver histopathological features of drug-induced liver injury (DILI) caused by Chinese herbal medicine (HM) and that caused by Western medicine (WM), and to investigate the pathological features of HM-DILI. MethodsA total of 50 patients with drug-induced liver injury(DILI) who were diagnosed and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from March 2014 to June 2019. All the patients with DILI were enrolled and divided into HM-DILI group and WM-DILI group. A retrospective analysis was performed for the clinical features and the pathological features of the two groups, including the clinical type of DILI, severity of liver injury, and liver histopathological features, especially location and grade of liver inflammation, type and degree of steatosis, and iron deposition. The t test and Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; the Mann-Whitney U test was used for comparison of ranked data. ResultsOf all 50 patients, 20 (40.0%) had HM-DILI and 30 (60%) had WM-DILI. There were no significant differences in sex, age, course of disease, and biochemical parameters of liver function between the two groups (all P>0.05). The main clinical types of the two groups were hepatocellular injury type and the degree of injury which was mainly grade l, and there were no significant differences in the clinical type of DILI and the severity of liver injury between the two groups (both P>0.05). As for liver histopathological features, both groups had varying degrees of focal necrosis of hepatocytes, steatosis (microvesicular, macrovesicular, and mixed), and fibrous tissue proliferation at the portal area, and compared with the WM-DILI group, the HM-DILI group had significantly greater lymphocyte/plasma cell infiltration in the portal area (χ2=3.860, P<0.05) and iron deposition in Kupffer cells (χ2=4787, P<0.05). ConclusionThere are no significant differences in clinical manifestations between HM-DILI and WM-DILI, but patients with HM-DILI have more obvious inflammation in the portal area and iron deposition in Kupffer cells than those with WM-DILI.

OBJECTIVETo confirm a new allele HLA-B*13:01:06 and analyze its nucleotide sequence.
METHODSGenomic DNA was extracted using a Qiagen DNA extraction kit. Nucleotide sequences of HLA-A, HLA-B, HLA-C and HLA-DRB1 were analyzed by polymerase chain reaction-sequence based typing (PCR-SBT). HLA high-resolution results were assigned, and the nucleotide sequences of HLA-B locus was compared with that of HLA-B*13:01:01.
RESULTSThe nucleotide sequence of the new allele shows a strong similarity to that of HLA-B*13:01:01. One nucleotide in exon 2 has changed from G to A at position 219 (codon 49 GCG>GCA), which however did not result in amino acid change.
CONCLUSIONThe novel allele verified by sequencing has been submitted to GenBank and officially named as HLA-B*13:01:06 by the World Health Organization HLA Nomenclature Committee.
