Clinical data of 289 patients aged 60 years old and above with acute intestinal obstruction operated in Drum Tower Hospital during June 2010 to December 2020 were analyzed retrospectively. Among 289 cases, 97 cases(33.6%)had tumor, 66(22.8%)had external hernias, 44(15.2%)had adhesions, 36(12.5%)had volvulus, 20(6.9%)had internal hernias, 8(2.8%)had intussusception and 18(6.2%)had other causes. Of 156 strangulated intestinal obstruction cases, 51 cases(32.7%)had external hernias,36(23.1%)had volvulus, 26(16.7%)had adhesions, 18(11.5%)had internal hernias, 14(9.0%)had tumor, 8(5.1%)had intussusception, and 3(1.9%)had other causes. There was a history of abdominal surgery in 88.6%(39/44)cases of adhesion, 85.0% (17/20) cases of internal hernia and 61.1%(22/36)cases of volvulus. For patients with acute intestinal obstruction caused by intestinal tumor, the cases of small bowel obstruction, strangulated intestinal obstruction and the strangulated large bowel were significantly less than those of large bowel obstruction, the non-strangulated intestinal obstruction and the non-strangulated large bowel obstruction (5 vs. 92, 14 vs. 80, 12 vs. 83, respectively; all P<0.05). For patients with strangulated intestinal obstruction caused by external hernias, volvulus, internal hernias and intussusception were significantly more than those with non-strangulated intestinal obstruction groups(51 vs.15, 36 vs. 0, 18 vs. 2, 8 vs. 0, respectively; P<0.05). The patients with strangulated large bowel obstruction caused by external hernias( n=4) and volvulus( n=9)were significantly more than those with non-strangulated large bowel obstruction( n=1 and 0, respectively; P<0.05). The patients with strangulated small bowel obstruction caused by adhesions( n=26)and volvulus( n=27)were significantly more than those with non-strangulated small bowel obstruction( n=18 and 0,respectively; P<0.05).The study showed that the principal causes of emergency operation for acute intestinal obstruction and strangulated intestinal obstruction are intestinal tumor and external hernias in elderly patients.

Objective To investigate the association between polymorphism of S1, S2 locus allele in ADAM 33 gene and chronic obstructive pulmonary disease (COPD) and lung function in Xinjiang Uygur population. Methods Blood sam?ples from 217 COPD patients and 218 healthy controls were collected. Samples of DNA was extracted, and S1, S2 single nu?cleotide polymorphism (ADAM 33) was detected by ABI SNaPshot SNP genotyping. Results There were no significant dif?ferences in the frequencies of S1 locus CC, CT, TT genotypes and C, T alleles between patient group and control group (P>0.05). There were no significant differences in the frequencies of S1 locus CC, CG, GG genotypes and C, G alleles between patient group and control group (P>0.05). In patient group, there were no significant differences in S1, S2 locus genotype and clinical indicators of lung function display, and in the FEV1%predicted and FEV1/FVC (P>0.05). Haplotype analysis showed that there were no significant differences in three kinds of haplotypes between patient group and control group ( P>0.05). Conclusion There is no significant difference in the polymorphism of S1, S2 locus allele in ADAM 33 gene and the susceptibility to COPD in Xinjiang Uygur population.

Influenza caused by influenza virus,seriously threaten human life and health.Drug treatment is one of the effective measurement. However, there are only two classes of drugs, one class is M2 blockers and another is neuraminidase (NA)inhibitors. The recent antiviral surveillance studies reported a global significant increase in M2 blocker resistance among influenza viruses, and the resistant virus strains against NA inhibitor are also reported in clinical treatment.Therefore thediscovery of new medicines with low resistance has become very urgent.As all known,traditional medicines with multi-target features and network mechanism often possess low resistance. Compound Yizhihao, which consists of radix isatidis,folium isatidis,Artemisia rupestris,is one of the famous traditional medicine for influenza treatment in China, however its mechanism of action against influenza is unclear. In this study, the multiple targets related with influenza disease and the known chemical constituents from Compound Yizhihao were collected, and multi-target QSAR (mt-QSAR) classification models were developed by Na?ve Bayesian algorithm and verified by various datasets. Then the classification models were applied to predict the effective constituents and their drug targets.Finally,the constituent-target-pathway network was constructed,which revealed the effective constituents and their network mechanism in Compound Yizhihao. This study will lay important basis for the clinical uses for influenza treatment and for the further research and development of the effective constituents.

This paper reported a new type of amylase (neoamylase) secreted by a Bacillus strain ZX99. The enzyme was a kind of ectoenzyme that could catalyze starch into isomalto-oligosaccharide effectively, but could not act on pullulan as substrate. The strain Bacillus ZX99 was mutated by ultraviolet ray and a mutant strain BS3.232 was screened. The activity of the neoamylase produced from BS3.232 increased by 60% over that from ZX99 under the same conditions. The results of thin-layer chromatography of products from starch and pullulan catalyzed by the enzyme demonstrated that the enzyme was different from neopullulanase and can be used to produce isomaltooligosaccharide from starch, including isomaltose, panose, isomaltotriose, isomaltotetose.

OBJECTIVET To explore the relationship between the expression of SOX4 gene and early recurrence of hepatocellular carcinoma (HCC) after curative resection.

METHODSSOX4 expression was detected immunohistochemically in 60 HCC patients including 30 with and 30 without early recurrence after curative resection, with 30 normal liver specimens as the control.

RESULTSThe expression of SOX4 was significantly higher in HCC than in normal liver (41.7% vs 16.7%, P<0.05), and in HCC tissues, the expression was significantly higher in early recurrent HCC after curative resection than in HCC without early recurrence (56.7% vs 26.7%, P<0.05). SOX4 expression was inversely correlated to the patients' gender, age, tumor size, HBsAg, and Edmonson grade (P<0.05).

CONCLUSIONSOX4 is closely associated with early recurrence of HCC after curative resection, and its overexpression may contribute to early recurrence of HCC. SOX4 may serve as a new molecular indicator for evaluating the prognosis of HCC.

A new method for the preparation of oligonucleotide microarray for gene expression detection was found. The key techniques and standards of quality controlling for preparation of oligonucleotide microarray was explored using gene of human 23 kD highly protein and Luciferase and mouse cytokine-associated genes. By the using of a software system MProbe, oligonucleotide probes were designed and BLAST. All the probes have a very high specificity, i.e. except target sequence, the similarity between the probe and non-target sequences is less than 70% and the hairpin structure are not exist in all probes. All the probes have the same length 40. GC contents in all probes are in a narrow scope (from 45% to 55%). All the probes are modified with amino at 5' or 3' terminal. The satisfied images with good sensitivity and very high specificity were obtained by the using of the methods above and also using of positive and negative controls and some internal controls(house keeping gene) to quantitate and balance expression of genes. High specificity, good sensitivity and stability have been verified by three continuous experiments using the oligonucleotide microarray to study gene expression profile of normal mouse breast grand tissue. The oligonucleotide microarray for expression detection prepared using our method have high specificity, good sensitivity and stability et al. It may be a more advanced method for analysis of gene expression profile.

OBJECTIVETo explore the expression of Survivin (SVV) protein in colorectal carcinogenesis and its clinical significance. METHODS Immunohistochemistry staining was performed by two-step EnVision technique for the paraffin sections, which included 90 adenomas, 25 ademomas with high-grade glandular intraepithelial neoplasia, and 108 colorectal adenocarcinomas.

RESULTSExpressions of SVV, P53, and Bcl-2 were observed in tumor cells of the sections. The positive rate of SVV in tubular adenomas, villous adenomas, and tubulovillous adenomas were 30% (12/40), 40.9% (9/22), and 35.8% (10/28), respectively. The positive rate of SVV in tubulovillous adenomas with high-grade glandular intraepithelial neoplasia were 68% (17/25). The positive rate of SVV in carcinomas of stage A, B, and C were 75% (27/36), 81.3% (26/ 32), and 95% (38/40), respectively. SVV expressions among the three types of adenomas without neoplasia were not significantly different (P > 0.05). SVV expression between each type of the above-mentioned ademoma and tubulovillous adenoma with high-grade glandular intraepithelial neoplasia or different Dukes stages of colorectal carcinoma was significantly different (P < 0.05). SVV expressions in adenocarcinomas and adenomas with high grade glandular intraepithelial neoplasia were significantly higher than those in adenomas (P < 0.01). The expressions of P53 and Bcl-2 had no significant difference among them. No association was noted between SVV expression and P53 or Bcl-2 expression (P = 0.487, P = 0. 437).

CONCLUSIONSSVV is abnormally expressed in the early stage of colorectal carcinogenesis, which may be correlated with the carcinogenesis of colorectal ademoma. SVV expression may be useful to distinguish adenocarcinoma from adenoma in colorectal carcinogenesis.

OBJECTIVETo establish a new method for the preparation of porcine acellular dermal matrix.

METHODSThe antigenicity of the porcine dermis was weakened by removing epidermal and dermal cells from the porcine skin through the digestion with low-concentration trypsin and repeated freeze-thaw cycles. Split thickness porcine skin was treated with 0.05% trypsin to remove the cells from the epidermis and dermis. Repeated freeze-thaw cycles were employed to further weed out the residual cells within the dermis. The prepared acellular dermis was then examined grossly, as well as histologically, and also by immunohistochemical method.

RESULTSNo cell could be identified in the prepared porcine acellular dermal matrix. The integral basement membrane was preserved on the surface of dermal matrix with compact dermal matrix collagen structure.

CONCLUSIONLow concentration trypsinization and repeated freeze-thaw cycles seemed to be a simple and effective method for the preparation of xenogeneic acellular dermal matrix.
