hMSH6 is one of the most important members in the mismatch repair family. Its polymorphism is closely related to the pathogenesis and development of neoplasm, particularly in colorectal cancer and endometrial cancer. Moreover, it has been suggested to play a more important role in endometrial cancer compared with hMLH1 and hMSH2.

With depth understanding of the mechanism of human leukocyte antigen G (HLA-G) protein,more and more studies have found that HLA-G is closely related with tumor immune escape.Numerous studies have shown that the expression of HLA-G protein and mRNA could be detected in patients with cancer.

Objective To investigate the relationship between the C161T polymorphisms in peroxisome proliferators-activated receptor γ (PPARγ) gene and atherothrombotic infarction (ATI) in a Chinese Han population.Methods The patients with atherothrombotic infarction and controls,who without histories of stroke,transient ischemic attack and myocardial infarction were enrolled.Genotypes of the PPARγ C161T polymorphisms were determined using the polymerase chain reaction-restriction fragment length polymorphism.The frequencies of genotype and allele in patients with ATI and controls were compared.Results A total of 112 ATI patients and 112 controls were enrolled.There were no significant differences in the age (67.9± 11.73 years vs.66.5 ± 10.35 years; t =0.386,P =0.701) and the proportion of male (61.61％ vs.58.04％ ;x2 =0.297,P =0.586) in the ATI group and the control group.The proportions of hypertension (59.82％ vs.44.62％ ;x2 =5.171,P =0.023),type 2 diabetes mellitus (26.79％ vs.9.82％;x2 =10.778,P =0.001) in the ATI group were significantly higher than those in the control group.Body mass index (25.13±1.86 kg/m2 vs.24.11 ± 1.81 kg/m2; t =3.543,P=0.001),systolic pressure (158.84 ± 20.15 mm Hg vs.135.82 ± 19.58 mm Hg; t =7.350,P =0.000),diastolic pressure (76.90 ± 13.64 mm Hg vs.68.90 ± 8.52 mm Hg; t =4.374,P =0.000) and the level of fasting blood glucose (6.523 ± 2.831 mmol/L vs.5.706 ± 2.177 mmol/L; t =2.026,P =0.044) in the ATI group were significantly higher than those in the control group.The genotype frequencies of CC,CT and TT in the ATI group were 77.7％,17.0％ and 5.4％,respectively,and in the control group were 69.6％,22.3％ and 8.0％,respectively.There were no significant difference between the two groups (x2 =1.909,P =0.385).The allele frequencies of C and T in the ATI group were 86.2％ and 13.8％,respectively,and in the control group were 80.8％ and 19.2％,respectively.There were no significant difference between the two groups (x2 =2.331,P =0.127).Conclusions PPARγ C161T polymorphisms may be not associated with the onset of ATI in a Chinese Han population.

Objective To explore the clinical efficacy and safety of closed negative pressure drainage(VSD) in the treatment of elderly patients with abdominal trauma and infection.Methods 82 elderly patients with abdominal trauma and infection were selected into clinical research,they were divided into two groups according to the treatment time number.41 cases of odd numbers were in the control group,they were given conventional dressing change and antibiotic therapy.41 cases of double numbers were in the observation group,they were given VSD therapy and antibiotic therapy.The clinical efficacy and safety after treatment was evaluated.Results The daily volume of the observation group [(48.67 ± 3.87) mL] was significantly increased compared with the control group,the dressing times [(8.59 ±1.04) times],hospitalization time [(18.33 ± 1.50) d] were significantly reduced compared with the control group,the differences were statistically significant(t =8.56,7.88,6.74,all P ＜ 0.05).The VAS score after treatment of the observation group was (3.38 ± 0.51)points,which was significantly lower than those before treatment and of the control group,the difference was statistically significant (t =8.06,7.56,all P ＜ 0.05).The infection control rate of the observation group was 92.68％,which was higher than that of control group,and the incidence of adverse reactions of the observation group was 4.88％,which was lower than that of the control group,the differences were statistically significant(x2 =6.87,7.69,all P ＜ 0.05).Conclusion The effect of vacuum sealing drainage technique in the treatment of elderly abdominal trauma and wound infection is significantly,it can effectively control the infection,reduce the number of dressing,relieve the pain of patients,and has the advantages of simple operation,high safety,which is suitable for promotion and application.

Results There were 300 cases of malignant tumor and 23 cases of benign tumor respectively. Non oncologic malady and benign tumor misdiagnosed as tumor or malignant tumor were 40 cases. The two leading malignant tumors were retinoblastoma and melanoma. Conclusion The clinical and pathological analysis of intraocular tumor is beneficial to the correct clinical diagnosis and treatment.

Theory of Shen-Xu Pang-Guang-Re (SXPGR) is an important part of the theory of zang-fu in traditional Chinese medicine (TCM). And it is the generalization for etiology and pathogenesis of Lin-Zheng (LZ). In immunology, mucosal immune system is composed of mucosal-associated lymphoid tissues and immune cells, which can resist the invasion of microorganisms. Mucosal immune plays an important role in the occurrence of urinary tract infection. This paper, which was based on SIgA and homing mechanism, was to investigate the relevance between mucosal immunity and the theory of SXPGR, in order to study the connotation of SXPGR in TCM.

Objective:To investigate the effect of arterialised Flow-through venous flap with palmaris longus tendon in repairing dorsal digit composite tissue defect.Methods:From March, 2010 to December, 2018, 23 cases (23 digits) of dorsal digit composite tissue defect were repaired with arterialised Flow-through venous flap with palmaris longus tendon. There were 17 males and 6 females aged between 23 to 53 (average, 37.2) years old. Causes of injury: 15 cases of strangulation, 5 of electric plane and 3 of thermal crush. Number of injured digit were 1 thumb, 11 index fingers, 9 middle fingers and 2 ring fingers. All of the injured digits had skin and extensor tendon defects with an area of 2.0 cm×1.8 cm-4.2 cm×2.6 cm, and the length of extensor tendon defect was 1.6-2.6 cm. One case had terminal and central tendon insertion defects and 5 suffered with terminal tendon insertion defect. Three cases were repaired by emergency surgery, and 20 were repaired by sub-emergency surgery. All donor sites were directly sutured. The shape, colour, texture, sensation, recovery of digit function and donor site appearance were followed-up at outpatient clinic.Results:The patients were followed-up for 8 to 23 (average, 11) months. The flap was soft, with mild pigmentation and recovery of protective sensation. The range of motion of the proximal and distal interphalangeal joints was 145°-170° (average,162.6°). According to Strickland hand function evaluation method, the results were excellent.Conclusion:The arterialised Flow-through venous flap with palmaris longus tendon is an ideal method in repair of the dorsal digit composite tissue defect.
