Objective: Many physicians and patients still have concerns about the safety of breastfeeding in mothers infected with hepatitis B virus; we evaluate the safety of the newborn and the women with HBeAg positive and high viral load, who received nucleoside analogues to block maternal to child transmisssion and selected postpartum breastfeeding after drug discontinuance. Methods: This prospective, observational study enrolled 60 HBeAg positive patients and HBV-DNA >2*10E+ 5 IU/ml, all patients started antiviral treatment for blocking maternal to child transmission at 24-28 weeks of pregnancy. All the newborns received the active-passive immunization therapy with hepatitis B immunoglobulin (HBIG) and HBVac. After the delivery, patients with normal liver function discontinued the antiviral drug and selected breastfeeding voluntarily. The safety of breastfeeding were compared with patients selected artificial feedings, they were followed up for 7 months. Primary measurements were the proportion of mothers with abormal liver function after stopping the drug and the level of newborn’s anti-HBs at 6 months of age; secondary measurements were the positive rate of neonatal HBsAg and the HBV-DNA value of the patients at 6 weeks postpartum. Results: From December 1, 2015 to May 1, 2017, 415 patients were enrolled in Beijing You’an Hospital Affiliated to the Capital Medical University and all these patients were born following full-term single-child pregnancy. After the delivery and drug withdrawal, there was no significant difference in the incidence of ALT elevation between the breast fed group and the artificially fed group: 29 /220 versus 30/195, (χ²=0.411, P=0.521). Patients continued to take the antiviral medicines between the breast feeding group and the artificial feeding group: 15 /220 versus 20/195, (χ²=1.487, P=0.223), there were no significant differences between them (P> 0.05). At the month 7, there were no significant difference between the breast fed group and the artificially fed group (747.62±374.08 mlU/ml versus 709.76±374.32 mlU/ml, t-value: 0.309, P-value>0.05). At birth, hepatitis B surface antigen (HBsAg) was detected in 15/220 and 20/195 of newborns in the breast feeding and artificially fed groups, respectively. At month 7, an intention-to-treat analysis indicated 0/220 of HBsAg infants from the breast fed versus 0/195 in the artificially fed group (P>0.05) and no significant difference was found in the rate of positive HBsAg between the two groups. In the breast fed group, the mean HBV DNA at baseline was significantly higher than that of the artificially fed group: (1.17±1.82) E+ 8 IU/ml versus (1.12±0.39)E+ 8 IU/ml, and the difference was statistically significant. Conclusions We have not found the relationship between the rate of neonatal infection and the increase of maternal abnormal liver function in HBeAg positive and high viral load patients, who chose breastfeeding after drug discontinuance.

OBJECTIVE: Distal pancreatectomy with splenectomy may be required for optimal cytoreductive surgery in patients with epithelial ovarian cancer (EOC) metastasized to splenic hilum. This study evaluates the morbidity and treatment outcomes of the uncommon procedure in the management of advanced or recurrent EOC. METHODS: This study recruited 18 patients who underwent distal pancreatectomy with splenectomy during cytoreductive surgery of EOC. Their clinicopathological characteristics and follow-up data were retrospectively analyzed. RESULTS: All tumors were confirmed as high-grade serous carcinomas. The median diameter of metastatic tumors located in splenic hilum was 3.5 cm (range, 1 to 10 cm). Optimal cytoreduction was achieved in all patients. Eight patients (44.4%) suffered from postoperative complications. The morbidity associated with distal pancreatectomy and splenectomy included pancreatic leakage (22.2%), encapsulated effusion in the left upper quadrant (11.1%), intra-abdominal infection (11.1%), pleural effusion with or without pulmonary atelectasis (11.1%), intestinal obstruction (5.6%), pneumonia (5.6%), postoperative hemorrhage (5.6%), and pancreatic pseudocyst (5.6%). There was no perioperative mortality. The majority of complications were treated successfully with conservative management. During the median follow-up duration of 25 months, nine patients experienced recurrence, and three patients died of the disease. The 2-year progression-free survival and overall survival were 40.2% and 84.8%, respectively. CONCLUSION: The inclusion of distal pancreatectomy with splenectomy as part of cytoreduction for the management of ovarian cancer was associated with high morbidity; however, the majority of complications could be managed with conservative therapy.

Traditional Chinese medicine considers that the final purpose of acupuncture treatment for disease is to harmonize yin and yang. Acupuncture redresses a balance between yin and yang by transmitting information to acupoints and then to corresponding visceral tissues and organs and the brain through the meridian system or the nervous system. In recent years, scholars at home thoroughly studied heart rate variability (HRV) analysis for acupuncture treatment of diseases and found that the regulating effect of acupuncture on visceral organs was closely related to autonomic nerves and acupuncture could restore a balance between sympathetic and parasympathetic nerves. Many scholars explored the effect of acupuncture on diseases related to autonomic nervous dysfunction by HRV frequency domain or time domain analysis and gained a certain achievements. This article summarizes recent years’ domestic studies on HRV-based analysis of acupuncture for diseases with autonomic nervous dysfunction and reviews the close relationship between autonomic nerves and diseases and the related mechanism of acupuncture action.

Objective The aim of this study is to evaluate the safety and efficacy of partial pancreatectomy as part of primary cytoreductive surgery in advanced epithelial ovarian cancer (EOC). Methods A total of 8 patients were recruited in this study who underwent partial pancreatectomy during the primary cytoreductive surgeries for advanced EOC in Fudan University Shanghai Cancer Center from April 2009 to July 2015. Their clinicopathological characteristics, diameter of metastatic tumors, the scope of cytoreductive surgeries, residual diseases after cytoreductive surgeries, postoperative complications and survival situation were retrospective analyzed. Results (1) Clinicopathological characteristics:the median age of these patients was 58 years old(range: 39-63 years old). The median value of preoperative serum CA125 was 1 688 kU/L(range: 119-5 000 kU/L). The median diameter of metastatic tumors involved in pancreatic body or tail was 4.5 cm (range:3-10 cm). All the tumors from the 8 patients were confirmed to be high-grade serous carcinoma. Four patients were staged as International Federation of Gynecology and Obstetrics (FIGO)Ⅳ, and the other 4 patients were staged as FIGOⅢc. (2) Tumor metastases and the scope of cytoreductive surgeries:all of these 8 patients had widely disseminated ovarian cancer, with involvement of upper abdominal, middle abdominal and pelvic cavity. Each patient underwent extensive intra-abdominal cytoreductive surgeries, including hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic periton-ectomy, splenectomy, partial pancreatectomy. Each patient had cytoreductive surgeries of 9.6 different sites on average. Of all 8 patients who underwent partial pancreatectomy, 7 patients had pancreatic tails removed;the other 1 patient had pancreatic body and tail removed. The median volume of blood loss during surgery was 1 350 ml(range:300-3 500 ml), blood transfusion was performed in 7 patients with the median volume of 1 150 ml (range: 500-1 800 ml). (3) Residual diseases after cytoreductive surgeries: optimal cytoreduction was achieved in all patients, with microscopic residual disease in 3 patients, residual tumors diameter < 0.5 cm in 3 patients, and residual tumors diameter between 0.5 and 1 cm in 2 patients. (4) Postoperative complications: 4 patients suffered from complications including pancreatic leakage (2/8), intraperitoneal hemorrhage (1/8) and pancreatic pseudocyst accompanied by infection (1/8). These complications were treated successfully by conservative managements. (5) Survival situation: during the median follow-up duration of 17 months (ranged from 2 to 46 months), 5 patients were still alive until the end of follow-up, including 4 cases under treatment and 1 case survived 29 months without relapse after treatment. Three patients were respectively died in 5, 20 and 46 months after surgery. Conclusion There is a higher risk of postoperative complications of pancreas resection as part of primary cytoreductive surgery in advanced epithelial ovarian cancer, but the resection of pancreatic metastases and part of the pancreas is feasible and necessary.

OBJECTIVETo explore the common causative genes and mutation sites for hereditary non-syndromic deafness in Shanxi.

METHODSPeripheral blood samples were collected from regional schools for children with deafness. The samples were analyzed by matrix-assisted laser desorption ionization of flight mass spectrometry, and the results were verified by DNA sequencing.

RESULTSFor all samples, the 20 mutational sites of the 4 common causative genes were tested. As revealed, c.235delC of GJB2 gene has the highest mutational rate (13.67%). c.IVS7-2A>G of SLC26A (PDS) gene has a mutation rate of 17.67%, and c.1555A>G of mitochondrial 12S rRNA has a mutation rate of 2.00%. No mutations have been found with GJB3 gene. Sequencing analysis has suggested that the above results have a consistency rate of 99%.

CONCLUSIONAnalysis of mutations of the 4 common deafness-related genes can facilitate early diagnosis and treatment for the disease. Matrix-assisted laser desorption ionization time of flight mass spectrometry is a reliable method for such a task.

Purpose To investigate the role of SOCS3 on diabetic renal injury. Methods Male CD-1 mice were randomly divided into four groups:control group, diabetic group, empty plasmid vector transfection group and SOCS3 plasmid transfection group. The diabet-ic mice were induced by intraperitoneal injection of STZ at a dose of 150 mg/kg body weight. The mice of transfection group were re-ceived an injection of SOCS3 plasmid or empty vector at every 7 days thereafter. Specimens were collected at 12 week after STZ injec-tion. The morphological changes of tubular epithelial cells were observed by transmission electron microscope. RT-PCR and immuno-histochemistry were used to determine the mRNA and protein expression of CK18 and α-SMA. Western blotting analysis was used to determine the protein expression of SOCS3, p-STAT3, CK18 and α-SMA. Results SOCS3 overexpression in kidney down-regulated the levels of p-STAT3 andα-SMA but up-regulated the expression of CK18. Conclusion Overexpression of SOCS3 can ameliorate the tubular epithelial-mesenchymal transdifferentiation of diabetic mice via inhibiting the phosphorylation of STAT3.
