A total of 166 women with intrahepatic cholestasis in pregnancy (ICP) participated in the study. Serum levels of thyroid stimulating hormone (TSH), free thyroxine 4 (FT4) and thyroid peroxidase antibody (TPOAb) were quantified for all of them with electrochemiluminescence (ECL) technique, and compared with those in normal pregnant women. Results showed that serum TSH and TPOAb [22. 9%(38/166)] increased significantly, but no significant change in serum level of FT4 was observed in women with ICP, as compared to those in normal pregnant women. Overall prevalence of thyroid diseases in ICP women was 35.5% (59/166), significantly higher than that in normal population screened for thyroid disease (17. 1%, 143/837) at the same time period. It suggests that thyroid dysfunction may be involved in pathogenesis of ICP.

Objective:To investigate the expression of human epidermal growth factor receptor 2 (HER2) in pancreatic ductal adenocarcinoma(PDAC) and its relationship with the prognosis of patients with PDAC.Methods:From January 2001 to December 2012, 109 paraffin embedded PDAC tissue samples and 27 normal pancreatic tissue samples were collected from the Department of Pathology, Huadong Hospital Affiliated to Fudan University. The expression of HER2 protein in pancreatic tissue was detected by immunohistochemical Envision two-step method. HER2 expression was evaluated according to Hercept test, and its relationship with clinicopathological features and survival time was analyzed.Results:The expression of HER2 protein was negative (-) in 29.4% of PDAC tissues, weakly positive (+ ) in 35.8%, positive (+ + ) in 25.7% and strongly positive (+ + + ) in 9.2%, respectively, and the overexpression rate (+ + , + + + ) was 34.9%; the negative (-) and weakly positive (+ ) expression of HER2 protein in normal pancreatic tissues accounted for 88.9% and 11.1% respectively. There was no expression with positive (+ + ) or strongly positive (+ + + ), therefore, the overexpression rate was 0. The overexpression rate of HER2 protein in PDAC and normal pancreatic tissues was significantly different ( P=0.000). The expression of HER2 protein was significantly correlated with age, and the expression of HER2 protein in patients with PDAC over 65 years old was significantly higher than that in patients with PDAC under 65 years old ( P=0.043), but not with gender, tumor location, tumor grade, T stage, N stage and nerve invasion (all P>0.05). Univariate Cox proportional hazards analysis showed that HER2 expression was associated with postoperative survival time of patients with PDAC ( P=0.032). Multivariate Cox proportional hazards analysis showed that HER2 expression was an independent prognostic factor for survival of patients with PDAC ( P=0.040). The median survival period of patients with HER2 expression + + + was significantly longer than that of patients with HER2 expression -~+ + (128.4 months vs 21.5 months), and the difference was statistically significant ( P=0.038). Conclusions:The overexpression of HER2 in PDAC tissue was related to the age of patients. The survival time of patients with HER2 strongly positive PDAC was significantly longer. HER2 can be considered as an index to evaluate the biological behavior and prognosis of PDAC.

INTRODUCTIONWe studied the automated intraretinal segmentation on Fourier domain optical coherence tomography (OCT).

MATERIALS AND METHODSThirty eyes from 30 normal subjects were studied using the RTVue-100. Both radial and raster scan protocol were performed 3 times on each subject. The OCT software performs automated intraretinal segmentation and provides macular thickness measurements.

RESULTSBoth scanning protocols provide reproducible inner, outer and full retinal thickness measurements. The inner, outer and full retinal thicknesses at the foveal central subfield were 67.31 +/- 12.27 microm, 151.67 +/- 12.96 microm, 219.33 +/- 23.19 microm, respectively by the raster scan, and 63.27 +/- 10.37 microm, 147.07 +/- 14.54 microm, 209.89 +/- 21.80 microm, respectively by the radial scan. Macular regional variations were consistently observed. The raster scan protocol gives greater retinal thickness measurements than the radial scan protocol (P <0.05), but the latter yields slightly more reproducible results.

CONCLUSIONSFourier domain OCT equipped with the ability to perform automatic intraretinal segmentation is a convenient tool in studying diseases that may differentially affect various parts of the retina. However, the establishment of normative values can be complicated by different scanning protocols, devices used, methods of data presentation and definition of intraretinal boundaries.

Objective: To analyze the clinical and laboratory abnormalities of two patients with α1-antitrypsin (α1-AT) Pittsburgh in a family and review the literatures. Methods: Both plasma clotting time and factor activities were performed using clotting or substrate methods. Platelet aggregation was evaluated using an optical aggregometer. The serum protein electrophoresis was performed on Sebia HYDRASYS by using Agarose gel. The exons of α1-AT were amplified by using polymerase chain reaction (PCR) and then sequenced and compared with NCBI GenBank records. Results: The proband had several ruptures of corpus luteum and bleeding after operation, while her daughter had no bleeding history. Both of them showed prolonged coagulation tests which could not be corrected by mixing with the normal plasma. They also showed low levels of plasma coagulation factors, undetected protein C and S activity and abnormal bands of α1-globulin. The results of gene sequencing demonstrated that they were heterozygous for g.T17132G (p.Met358Arg) mutation of α1-antitrypsin gene (NG_008290.1) . Conclusions Comparing with the data of previously reported cases, our results confirmed the obvious abnormality of coagulation test and the discrepancy of bleeding tendency of α1-antitrypsin Pittsburgh patients, and suggested that the rupture of corpus luteum would be a specific characteristic in women of child-bearing age.

In the past 30 years, with the advancement of functional neurosurgery, neuroelectrophysiology and neuroimaging, deep brain stimulation (DBS), as a new tool for the treatment of dyskinesia, has been considered to have underwent the fastest development in this field.Many patients with dyskinesias have significantly improved their main clinical symptoms after treatment with DBS, some of the improvement are even dramatic.Due to its minimally invasive characteristics, reversibility and adjustability, DBS therapy has been increasingly used in the treatment of dystonia in children.Hereditary dystonia is the most common type of dyskinesia in children, and there is no effective treatment yet.Recently, some dyskinesia at home and abroad centers have carried out DBS treatment for pediatric hereditary dystonia and achieved some encouraging results.Now, the effect of DBS in the treatment of hereditary dystonia in children and the main process of DBS treatment were mainly discussed, and shared the experience based on the clinical practices of Multidisciplinary Collaborative Diagnosis and Treatment Center for Children′s Motor Disorders, Peking University First Hospital.

Objective: To observe the material basis and mechanism of action of Kai-Xin-San (KXS) in regulating antidepression of neurotrophic factors. Methods: KXS eluted by ethanol on macroporous resin was prepared. The antidepressive effect of different components was compared by tailing suspension test and forced swimming test of mice. The levels of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in hippocampus were determined by ELISA. The rat astrocyte glioma C6 cell line and the rat adrenal pheochromocytoma PC12 cell line were used to evaluate the effects of different ethanol elution sites on the expression of NGF and BDNF and the differentiation of PC12 cells.Results: All of the ethanol elution components from KXS exerted anti-depressive effects by shorting the immobile time of tailing suspension and forced swimming of mice and 70％ ethanol elution components exerted best efficacy. This site also could increase expressions of NGF and BDNF on C6 glioma cell line. The 10％ ethanol elution site had the strongest ability to promote PC12 cell differentiation. Ginsenosides were the main effectuve ingredients for promoting the expression of neurotrophic factors. Conclusion: Regulation of neurotrophic factors might be the prominent action mechanism of KXS exerting anti-depressive effects.

Objective:To analyze the clinical characteristics of novel coronavirus (COVID-19) infection in liver transplant recipients.Methods:Clinical data of 130 liver transplant recipients with COVID-19 infection followed in Hebei Medical University Third Hospital from November 2022 to January 2023 were retrospectively collected, including 103 males and 27 females, aged (53.6±11.4) years. The severity of COVID-19 infection, its clinical symptoms, and negative conversion time for each recipient were analyzed and compared.Results:For the disease severity, 121 (93.1%) were mild, 5 (3.8%) were moderate, 3 (2.3%) were severe, and 1 (0.8%) was critically severe. The most common symptoms in the 126 patients with mild to moderate COVID-19 infection were successively fever, fatigue, cough and myalgia, with a negative conversion time of (10.1±4.5) (3.0-29.0)d. In those who underwent transplantation less than 12 months ( n=28), those who were taking mycophenolate mofetil ( n=53) and those who were taking methylprednisolone ( n=10), the negative conversion time was (11.6±5.1) d, (11.4±5.4) d, and (13.4±6.4) d, respectively, longer compared to those who underwent transplantation more than 12 months (9.7±4.2 d, n=98), and who were not taking mycophenolate mofetil (9.2±3.4 d, n=73) or methylprednisolone (9.8±4.2 d, n=116, all P<0.05). The negative conversion times were longer in recipients with symptoms (eg. fatigue and cough) than those in asymptomatic recipients (11.0±5.1 d vs. 9.0±3.3 d, t=2.64, P=0.009, and 11.4±5.2 d vs. 9.0±3.4 d, t=2.92, P=0.004). Conclusion:The COVID-19 infection in liver transplant recipients was mainly mild and moderate. The most common symptoms are fever, fatigue, cough and myalgia. The short time (less than 12 months) after liver transplantation, oral mycophenolate mofetil and methylprednisolone, with symptoms (fatigue and cough) could be associated with a prolonged negative conversion time.
