Hereditary nonpolyposis colorectal cancer (HNPCC) is a distinct autosomal dominant syndrome, accounting for 5%-10% of the total colorectal cancer population. To date, we have noticed that patients with HNPCC inherit a germline mutation in one of the genes responsible for repair of DNA mismatch errors. Tumors of HNPCC show a high frequency of microsatellite instability. Identifying individuals afflicted with HNPCC has implications for surgical management, prognosis, follow up, and surveillance of HNPCC patients and family members at risk.

Objective To investigate the clinicopathologic features of sporadic colorectal cancers with CpG island methylator phenotype. Methods The methylation of the promotors of the five genes including p14, hMLH1, p16, MGMT and MINT1 were detected using methylation specific PCR in 71 patients to determine the clinicopathologic characteristics of sporadic colorectal cancers with CpG island methylator phenotype. Results Fifteen out of 71 (21. 1%) patients were positive for the CpG island methylator phenotype. The proportion of the right-sided colonic cancers(40. 0% vs. 12. 5% , P

Purpose:To explore the clinicopathologic features of sporadic colorectal cancer patients with microsatellite instability(MSI) and the correlation between the microsatellite instability and the DNA ploidy.Methods:Detecting microsatellite instability with two sites(BAT25 and BAT26),conduct flow cytometry to analyze the DNA ploidy among 71 sporadic colorectal cancer patients and probe into the relationship between the microsatellite instability phenotype and the clinicopathologic characteristics as well as the DNA ploidy.Results:The positive rate of the microsatellite instability among sporadic colorectal cancer patients was 9.86 percent.The microsatellite instability phenotype was correlated with the tumor site and the histopathologic type and the differentiation grade with the P value less than 0.05,while it was independent of the gender,age,lymph node metastasis and Dukes' stage.The proportion of right colon cancers and poorly-differentiated adenocarcinomas of sporadic colorectal cancers showing microsatellite instability was higher than that of microsatellite stable ones.18 and 50 cases showed diploidy and aneuploidy respectively.5 cases of MSI were diploid,There was statistically significant correlation between the microsatellite instability phenotype and the DNA ploidy(P=0.012).Conclusions:Sporadic colorectal cancers with microsatellite instability were prone to occur in the right colon and to be poorly-differentiated adenocarcinomas and inclined to be diploid.

Stroke is one of the most common diseases among middle and senior - aged people,and depressive disorder,which hinders severely recovery and prognosis,is one of the complications of stroke.This paper analyzes the efficiency of social intervention mode on patients with post - stroke depressive disorder,and comes up with the conclusion that social intervention mode can not only help to ameliorate the occurrence of post - stroke depressive disorder,but also promote the recovery of patients' nervous function.Therefore,the social intervention mode can be regarded as an effective means for medical treatment.

Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

Objective To evaluate the clinical outcomes of intravesical instillation of resiniferatoxin (RTX) for the treatment of overactive bladder(OAB). Methods 30 patients (28 females and 2 males) included in the study.The mean age was 39 years (range,21 to 60 years).The mean course of the illness was 6.9 years (range,2 to 30 years).The voiding diaries of pretreatment showed that frequency at day time varied from 9 to 26 times with a mean of 15.0 times;frequency at night ranged from 3 to 13 times with a mean of 6.4 times.Of the 12 patients undergoing cystoscopy 10 had chronic inflammation in both mucous and submucous.Based on biopsy 1 case was pathologically diagnosed as glandulous cystitis,2 as interstitial cystitis,and others as chronic inflammation.100 ml of RTX at a concentration of 100 nmol/L was intravesically instillated in all the patients and was retained within the bladder for 30 minutes. Results RTX instillation had no vesical irritation and other adverse effects,and no local anesthesia was required.The symptoms were improved immediately in all the patients after 1 day of RTX intervention.The decreases in both diurnal (5 to 15 times,mean 8.9 times) and nocturnal (0 to 5 times,mean 3.0 times) frequencies were significant(P

OBJECTIVETo compare the efficacy between moxa salt packets at acupoints combined with tropisetron hydrochloride and single use of tropisetron hydrochloride for cisplatin chemotherapy-induced gastrointestinal reaction.
METHODSSixty patients with malignant tumor who met inclusive criteria and received chemotherapy for the first time were recruited and randomly divided into an observation group and a control group, 30 cases in each one. Between the first days and fifth day into the chemotherapy, the patients in the control group were treated with daily intravenous injection of tropisetron hydrochloride (5 mg), while patients in the observation group, based on the treatment of control group, were treated with moxa salt packets at Zhongwan (CV 12). The nausea and vomiting between the first days and fifth day into the chemotherapy were compared in the two groups, and the occurrence rates of adverse reactions within the first week into chemotherapy were recorded.
RESULTSBetween the second day and fifth day into the chemotherapy, the effective rate for nausea in the observation group was higher than that in the control group (all P < 0.05); between the third day and fifth day into the chemotherapy, the effective rate for vomiting in the observation group was higher than that in the control group (all P < 0.05); one week into the chemotherapy, the occurrence rate of constipation in the observation group was lower than that in the control group (P < 0.05).
CONCLUSIONThe moxa salt packets combined with tropisetron hydrochloride can effectively reduce the cisplatin chemotherapy-induced nausea and vomiting as well as the occurrence rate of delayed-type vomiting, and improve the constipation, which is superior to single use of tropisetron hydrochloride.

Objective To understand the RHD gene profiles of RhD negative individuals in Hainan Han population,and provide reference to establish the right method for RHD genotyping.Methods RhD was tested by anti-globulin test, and RhDel and genuine RhD-negative phenotype were identified by absorption/elution method. RhD negative samples were further tested for RHD exons by PCR-SSP.The RhD negative samples with intact RHD genes were further analyzed by PCR-SSP for RHD introns 2, 10 and RHD?gene. Results Thirty-one (29.25%)cases of RhDel individuals were identified among 106 apparent RhD-negative individuals. All RhDel samples had RHD genes;67 cases of genuine RhD-negative had no RHD genes and 8 cases were partial D. All 31 RhDel samples had Din2 and Din10 but none had RHD?. Additionally, We detected exons 1,3,4,6,7,9 and 10 in one case of ccdEe sample. Conclusion The proportion of RhDel phenotype is high among apparent RhD-negative Hainanese, and total RHD exons can be detected in all RhDel samples. Polymorphisms of RHD gene are present among genuine RhD-negative Hainanese. There is no exon 5 in all 8 cases of partial D, which suggests that exon 5 specific amplification may be very important in RHD genotyping for Hainan Han population.
