Objective To assess the efficacy of subcutaneous tunnel and hepatocholangioplasty using the gallbladder (STHG) in the treatment of hepatolithiasis. Methods A retrospective analysis was done on 43 patients with hepatolithiasis who underwent STHG between June 2001 and May 2008. The strictured bile duct at the hilus was opened after removing the stones or cutting the damaged liver segments. The gallbladder was anastomosed to the widely opened bile duct in the hilus to form a widened pass way through the intrahepatic to the extrahepatic ducts. And the fundus of the gallbladder was mobilized and pulled to the abdominal wall to form a subcutaneous tunnel as a re-entry to the biliary tree. Results Totally 18 patients (41.9%) underwent resection of the liver,17 patients (39.5%) had residual stones. The rate of residual stone was 27.8% (5/18) in those treated by STHG combined with hepatectomy,and 48.0% (12/25) in those received STHG only. One patient developed biliary leakage and 1 patient had fungous infection after the operation. The 43 patients were followed up for a mean of 27.6 months (range,1-83). During the period,3 patients had recurrence of cholangitis and hepatolithiasis,1 showed cholangitis,and 1 had recurrent stones. The recurrent cases were cured by drainage or removing the stones through the subcutaneous tunnel. Conclusion STHG is safe,effective,minimally invasive and easy to manipulate for the treatment of hepatolithiasis.

Objective Brain metastasis(BM) is unusual in colorectal carcinoma(CRC) patients.This study was to evaluate the characteristics and prognosis of brain metastasis of colorectal carcinoma patients.Methods Twenty-eight consecutive CRC patients underwent surgical resection for BM between January 2001 and December 2008.The clinical data were analyzed by univariate (logrank) and Cox regression test.Results The median age at BM diagnosis from CRC was 57 years(41-75 years).Median survival after neurosurgical intervention was 9.4 months.The 1-year and 5-year survival rates were 28.9%and 7.1%,respectively.Seventeen patients(61%)had concurrent systemic metastasis.All patients were symptomatic with neurologic deficits and symptoms.On multivariate analysis,gender,infratentorial location of lesions and characteristics of primary CRC had no significant impact on survival.Two factors were signitlcandy associated with better survival:single brain metastases and absence of extracranial metastases.Perioperative mortality was zero.There were no difference of survival among patients undergoing resection alone and resection combined with whole brain radiotherapy (WBRT) or stereotactic radiosurgery(SRS). Conclusions Brain metastases from colorectal cancer is an evil omen of poor prognosis of CRC patients.Sursical resection of symptomatic brain metastases from colorectal cancer is relatively safe and provides the opportunity for prolonged survival.

Nucleobindin2protein(NUCB2)isanewlydiscoveredneuropeptideprecursorprotein, which has a comprehensive cytology function and is expressed in the hypothalamus nucleus and many peripheral tissues.There aren′t many studies about its signaling pathway,where neuroendocrine regulation,cell survival growth,tumor suppressor,cytokine secretion were found to involve in it.Besides,it has also been confirmed that breast cancer,lung cancer,ovarian cancer and prostate cancer are closely related to NUCB2.Therefore, several downstream pathways of NUCB2 may be related to the formation and progression of tumor.Further stud-ies are still needed to clarify the signal pathways of NUCB2 to provide a reliable basis for clinical cancer preven-tion.

Objective To investigate the hospitalized patients incidence of nutritional risk and nutritional support in six departments (general surgery, thoracic surgery, gastroenterology, neurology, urology and respirology) in a middle hospital and in the medical/surgical departments in a small hospital, so provide reference for rational nutritional support for patients. Method Nutritional Risk Screening 2002 was used to assess the existence of nutritional risk and the necessity of nutritional support. Results The overall prevalence of the nutrition risk was 25% in the six departments in the middle hospital; more specifically, the prevalence of nutrition risk arranged from 18% to 31% in these six departments: 31% in the department of respiratory medicine, 29% in the department of neurology, 27% in the department of urology, 23% in the department of thoracicsurgery, 22% in the department of gastroenterology, and 18% in the department of general surgery. For those at nutritional risk, the nutritional support rate was 24%. For non-risky patients, 9% received nutritional support. The overall prevalence of nutrition risk was 18% in the small hospital; more specifically, the prevalence of nutrition risk was 29% in the department of internal medicine and 7% in the department of surgery. For those at nutritional risk, the nutritional support rate was 24%.For non-risky patients, the nutritional support rate was 4%. Conclusions Certain nutritional risk and malnutrition exist in inpatients in the middle and small hospitals in Shijiazhuang. The applications of parenteral and enteral nutritions still have some problems. It is of particular importance to further promote the application of evidence-based parenteral/enteral nutrition guidelines in middle and small hospitals to standardize the application of nutritional support.

Objective To explore the role of 3D venous-fusion models in the resection of meningiomas.Methods The study included 19 patients with meningiomas,admitted to our hospital from March 2015 to July 2015.The preoperative and postoperative contrast enhancement MR venography (CE-MRV) data were imported into the neuronavigator system.The establishment of 3D venous-fusion models was performed;reconstruction,cropping,fusion of the intracranial venae and tumors were performed.3D venous-fusion models were used to evaluate the intracranial venous circulation,and the positions of venae and tumors were navigated in real-time.Results 3D venous-fusion models showed good results.The position relationship of tumors and their surrounding venous was perfectly assessed in operation.Nineteen patients underwent craniotomy using neuronavigator to locate venous position,and no postoperative venous complications occurred.The contrast of preoperative and postoperative 3D venous-fusion models prompted that the venous protection was in line with expectations.Conclusions The 3D venous-fusion models established by neuronavigator can accurately evaluate the relationship between cerebral venous and the tumors.These models help the operator making a better understanding of tumors and their peripheral venous imaging data from 3D perspective.It is benefit for the operator to make a more reasonable venous protect strategy.

OBJECTIVETo determine the nature of genomic copy number variations (CNVs) in two fetuses with congenital heart defects (CHD) and explore the correlation between 3q microdeletions and CHD.

METHODSGenomic DNA was extracted from fetal umbilical cord tissue, and chromosome copy number variations were detected by low coverage whole genome sequencing.

RESULTSBoth fetuses had microdeletions of the long arm of chromosome 3. Fetus 1 had ventricular septal defect, cleft lip and palate, and a 1.66 Mb deletion on 3q29. The deleted region encompassed all of the critical genes for 3q29 microdeletion syndrome. Fetus 2 had overriding aorta, ventricular septal defect, and a novel 240 kb deletion on 3q28.

CONCLUSION3q29 microdeletion may result in CHD in combination with cleft lip and palate. Genomic CNVs can be detected by low coverage whole genome sequencing.

Objective: To understand the possible transmission route of a family cluster of COVID-19 in Zhengzhou and the potential infectivity of COVID-19 in incubation period, and provide scientific evidence for the timely control of infectious source and curb the spread of the epidemic. Methods: Epidemiological investigation was conducted for a family cluster of COVID-19 (8 cases) with descriptive epidemiological method, and respiratory tract samples of the cases were collected for the nucleic acid detection of 2019-nCoV by RT-PCR. Results: Two primary cases, which occurred on 31 January and 1 February, 2020, respectively, had a common exposure history in Wuhan. The other six family members had onsets on 30 January, 31 January, 1 February (three cases) and 3 February, 2020. Conclusions In this family cluster of COVID-19, six family members were infected through common family exposure to the 2 primary cases. Five secondary cases had onsets earlier than or on the same day as the primary cases, indicating that COVID-19 is contagious in incubation period, and the home isolation in the early phase of the epidemic might lead to the risk of family cluster of COVID-19.
