Objective To investigate the efficacy of transcranial direct current stimulation(tDCS)on sleep disorder in patients with Parkinson's disease(PD).Methods From July 2021 to July 2023,patients with PD and sleep disorders in the Department of Neurosurgery of the Second People's Hospital of Guangdong Province were selected.The enrolled patients were divided into sham stimulation group(n=28)and true stimulation group(tDCS)(n=29)according to the inclusion and exclusion criteria.MDS-UPDRS,PDSS and other rating scales were used to evaluate the patients.Before and after tDCS treatment,MS-11 was used for intelligent sleep monitor-ing.The baseline and improvement of sleep disorders in the two groups before and after treatment were analyzed.Results Before tDCS treatment,there was no significant difference in general conditions and scale scores between the two groups(P＞0.05).There was no significant difference in polysomnographic monitoring results between the two groups before treatment(P＞0.05).Compared with pre-treatment,there was no significant difference in sleep monitoring results in the sham stimulation group(P＞0.05),while the sleep duration and sleep efficiency signifi-cantly increased,the nighttime awakening duration,nighttime awakening frequency,MDS-UPDRS-Ⅲ score,and LEDD dose significantly decreased in the true stimulation group,with statistical significance(P＜0.05).Conclusion Pharmacological treatment combined with tDCS treatment is effective for sleep disorders and motor function in patients with PD,which could increase the sleep duration and sleep efficiency of PD patients with sleep disorders to a certain extent,reduce the nighttime awakening duration and frequency,thereby improving the fatigue symp-toms during the daytime,and improving the efficacy of conventional pharmacological treatment for PD.

Objective:To screen the differentially expressed genes(DEGs)under high phosphate-induced calcification in the vascular smooth muscle cells(VSMCs)by mRNA high-throughput sequencing technology,and to analyze the key genes and signaling pathways involved in the VSMCs calcification.Methods:The human VSMCs were divided into control group and model group.The cells in model group was exposed to the high-phosphate medium,while the cells in control group were cultured in DMEM supplemented with 10%fetal bovine serum under the same conditions.The VSMCs in two groups,stably transfected,were cultured for 12 d.The morphology of the cells in two groups were observed and photographed under inverted microscope.The DEGs were selected by Hisat2 software,and Gene Ontology(GO)functional and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were performed by Stringtie software from three aspects,such as biological processes(BP),molecular functions(MF),and cellular components(CC).The calcification of the cells in two groups was observed by Von Kossa staining method.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to analyze the expression levels of alkaline phosphatase(ALP),bone morphogenetic protein 2(BMP2),alpha-smooth muscle actin(α-SMA),tumor protein 53(Tp53),glutathione peroxidase 4(GPX4),ferritin light chain 1(Ftl1),and glycosylphosphatidylinositol-specific phospholipase D1(GPLD1)mRNA in the cells in two groups.Results:Compared with control group,there were 2 524 DEGs in the cells in model group,and there were 1 368 upregulated DEGs and 1 156 downregulated DEGs.Clustering of DEGs between the cells in two groups was distinct.The GO functional and KEGG pathway enrichment analysis results showed that the upregulated DEGs were primarily involved in regulating the microtubule cytoskeleton,cell polarity,protein localization,and cell cycle regulation among BPs;in constructing cell membrane,microtubule organization,chromosomes,and kinetochore among CCs;and functioning in phosphatidylinositol phosphate,Rho GTPase protein binding,transmembrane transport,and protein kinase regulatory activity among MFs.Downregulated DEGs were mainly involved in cytoplasmic translation,protein membrane localization,mRNA metabolism,and protein endoplasmic reticulum localization among BPs;in forming ribosome subunits,cell membrane,and autophagy among CCs;and functioning in single-stranded DNA,ribonucleoprotein complex,growth factor binding,regulating protein kinase activity,and catalytic activity among MFs.Seven signaling pathways were significantly enriched in upregulated genes,most notably in the biosynthesis of glycosylphosphatidylinositol(GPI)anchors;whereas 18 signaling pathways were significantly enriched in the downregulated genes,most notably in ferroptosis.The RT-qPCR results showed that compared with control group,the expression levels of GPX4,Ftl1,and Tp53 mRNA in the cells in model group were significantly decreased(P<0.01),while the expression level of GPLD1 mRNA was significantly increased(P<0.01);compared with control group,the expression level of α-SMA mRNA in the cells in model group was significantly decreased(P<0.01),and the expression levels of ALP and BMP2 mRNA were significantly increased(P<0.01).Conclusion:The VSMCs underwent calcification and normal cells exhibit the DEGs.The key signaling pathways in the calcification induced by high phosphate in the VSMCs include ferroptosis and GPI anchor biosynthesis,mediated primarily through GPX4,Ftl1,Tp53,and GPLD1.

Objective:To discuss the long-term survival and risk factors of thyroid cancer in the real world in China.Methods:The clinical data of thyroid cancer patients who underwent initial surgery from Apr. 1998 to Dec. 2018 were retrospectively analyzed, including patients’sex, age, surgical records, pathology, hospitalization records and follow-up. According to the prognosis, the patients were divided into disease-free survival group and recurrence/metastasis/death group. Univariate analysis and multivariate regression analysis were conducted to analyze the risk factors affecting the prognosis of thyroid cancer. The clinical features and prognostic risk factors of thyroid cancer patients were investigated.Results:A total of 2038 cases were collected, and the longest follow-up time was more than 20 years. A total of 1876 cases were included in the study, 162 cases were lost, and the rate of follow-up was 7.9%. Among them, 1858 survived, the overall survival rate was 99.04%; 18 died, and the overall mortality rate was 0.96%. According to the prognosis of thyroid cancer, the patients were divided into 2 groups, including 1808 cases in the disease-free survival group and 68 cases in the relapsed-metastatic-death group. The study found that there were statistical differences between the two groups in terms of patients’age [ (45.40±11.016) vs (51.53±15.199, P=0.000) , the male ratio (32.854%, 48.529%, P=0.001) , whether tumor breaks through capsule (20.077%, 33.823%, P=0.006) , central lymph node metastasis (48.834%, 70.588%, P=0.001) and lateral lymph node metastasis (31.084%, 55.882%, P=0.000) , and there was no difference between the number of tumor lesions. Conclusion:Thyroid cancer has a good prognosis, but according to the characteristics of patients with thyroid cancer in my country, it should still be treated early in the clinic, and the standardization and thoroughness of surgery should be adhered to during the treatment.

Objective:To assess the impact of timing of percutaneous catheter drainage (PCD) application (ANC and WON) on outcomes and complications in severe acute pancreatitis (SAP) treatment.Methods:The clinical data of 75 SAP patients treated with PCD from Jan. 1, 2018 to Dec.31, 2018 in Pancreatitis Treatment Center of Deyang People’s Hospital were retrospectively analyzed. The clinical manifestations, application period and curative effect of PCD were analyzed.Results:Among the 75 patients, 51 (68%) were ANC patients, (32%) were WON patients, 0 (0%) died, 70 (93.3%) were cured, and 5 (6.7%) underwent further surgical treatment. There was no significant difference between the average time of PCD application, or complications (such as pancreatic fistulae, catheter obstruction or falling and haemorrhage) ( P>0.05) . Conclusion:Percutaneous catheter drainage in different stages of acute necrotizing pancreatitis does not affect its safety and efficacy, and delayed use don’t have better curative effect.

Objective:To explore the interobserver variabilities in the delineation of the target volume using simulation three-dimensional computed tomography (3DCT) between the supine and prone positions for external-beam partial breast irradiation (EB-PBI) after breast-conserving surgery (BCS).Methods:Twenty-seven breast cancer patients who were scheduled to receive EB-PBI after BCS from July 2016 to April 2017 were enrolled in this study. All patients underwent axial 3DCT simulation scanning in the supine and prone positions during free breathing. Based on two different simulation 3DCT acquired, the gross target volume (TB) formed by using surgical clips and the clinical target volume (CTV) were delineated by five radiologists using specific guidelines. The following parameters including the target volume, coefficient of variations (COV) and matching degree (MD) were calculated to analyze the interobserver variability. Twenty-seven breast cancer patients who were scheduled to receive EB-PBI after BCS from July 2016 to April 2017 were enrolled in this study.Results:Whether in the supine or prone position, the interobserver variabilities for TB and CTV were statistically significant ( P<0.001, P=0.001, P<0.001, P=0.001). And the intersection of CTV in the prone position was 5.79 cm 3 greater than that in the supine position ( P=0.011). The interobserver variability of COV CTV in the prone positionwas significantly lower than that in the supine position ( P=0.014). And the interobserver variabilities of MDTB TB and MDTB CTV in the prone positionwere statistically greater than those in the supine position, respectively ( P<0.001, P= 0.001). Conclusions:When delineating the target volume of EB-PBI in the prone position, the interobsever variability can be reduced compared with that in the supine position. Hence, it is more reasonable to carry out EB-PBI in the prone position in free breathing.

Objective To study the relationship between uridine diphosphate glucuronic acid (UGT1A1) gene polymorphism and unexplained neonatal unconjugated hyperbilirubinemia in Jinhua.Method Full-term infants with unidentified non-binding hyperbilirubinemia were selected as hyperbilirubinemia group from January 2016 to December 2017 in the obstetrics or neonatal intensive care unit of Jinhua Central Hospital,healthy full-term neonates and those with physiological jaundice admitted during the same period were selected as control group.Whole blood DNA was extracted and UGT1A1 was sequenced and then annotated with human gene mutation database.The distribution and frequency of UGT1A1 genotype were analyzed.The correlation between different genotypes and unexplained unconjugated hyperbilirubinemia in neonates was also studied.Result Two hundred and forty cases were enrolled in the hyperbilirubinemia group,and 216 cases were enrolled in the control group.Four single nucleotide variation (SNV) sites associated with the disease were found on UGT1A1,which were c.211G＞A (Gly71Arg),c.686C＞A (Pro229Gln),c.1091C＞T (Pro364Leu) and c.1456T＞G (Tyr486Asp),accounting for 83.9％(141/168),1.8％(3/168),8.9％(15/168) and 5.4％(9/168) in the experimental group respectively.The genotype frequency and allele frequency analysis showed that the distribution of the two SNV sites of c.211G＞A and c.1456T＞G were statistically different between the experimental group and the control group (P＜0.05),whereas there was no statistical difference of the other two SNV sites of c.686C＞A and c.1091C＞T between the two groups.Binary Logistic regression analysis showed that c.211G＞A and c.1456T＞G were related to the occurrence of unexplained hyperbilirubinemia,The OR values (95％CI) were 5.412 (3.567～ 8.212) and 8.377 (1.052～66.670) respectively,but no correlation was found of the other two polymorphic loci.At the different genotypes of c.211G＞A locus,the levels of total bilirubin and non-binding bilirubin in infants with homozygous mutant (AA) were higher than those in infants with heterozygous mutant (GA) and wild type (GG),which was statistically significant (P＜0.05).Conclusion The most common mutation site of the UGT1A1 gene in Jinhua is c.211G＞A.The mutations of c.211G＞A and c.1456T＞G are risk factors forunconjugated hyperbilirubinemia in neonates.Of the different genotypes of c.211G＞A locus,the serum bilirubin level of homozygous mutant group was significantly higher than heterozygous mutant group and wild type group.

Four cases of Pentalogy of Cantrell were diagnosed by prenatal ultrasonography and confirmed by autopsy after labor induction.There were 1 case of complete Pentalogy of Cantrell and 3 cases of incomplete Pentalogy.In 3 cases of incomplete Pentalogy of Cantrell,1 case presented with high umbilical cord prolapse,extraspectoral heart,partial defect of the lower part of the sternum,partial defect of the pericardium,single umbilical artery and cervical lymphatic cyst;1 case presented with high umbilical cord prolapse,extraspectoral heart,thoracic fissure and ventricular septal defect;and 1 case presented with umbilical cord,extraspectoral heart,partial inferior sternal segment defect,ventricular septal defect and bilateral clubfoot varus.In l case of complete Pentalogy of Cantrell,there were high umbilical cord bulge,extraspectoral heart,chest fissure and inferior segment defect,anterior diaphragm and pericardium defect,total forebrain deformity,right 12th ribs loss and ventricular septal defect.Ectopic heart and omphalocele are typical echographic features of Pentalogy of Cantrel and prenatal ultrasonography is of important value in early diagnosis of this congenital malformation.

Objective To investigate the therapeutic outcomes of unilateral adrenalectomy for Cushing syndrome in patients with adrenocorticotropic hormone (ACTH) independent bilateral macronodular adrenal hyperplasia.Methods 22 patients diagnosed with Cushing syndrome caused by ACTH independent bilateral macronodular adrenal hyperplasia from January 2005 to December 2015 were retrospectively concluded.There are 17 male patients and 5 female patients with the median age of 46.5 years.All patients were presented with Cushing syndrome such as moon face, buffalo hump and other typical symptoms of Cushing syndrome.The laboratory tests showed disappearance of cortisol rhythm, elevated 24-hour urinary free cortisol, suppressed or normal ACTH and unsuppressed low dose dexamethasone suppressing test.CT scan showed bilateral macronodular adrenal hyperplasia in all patients.Results All the patients received unilateral adrenalectomy.Pathological results showed adrenal cortex nodular hyperplasia.16 patients had reexamination in the endocrine department.The median follow-up time was 26 (17-118)months for these 16 patients.In the follow-up between 3 to 9 months after surgery, laboratory test showed serum and urinary cortisol level returned to normal range and Cushing syndrome also disappeared in these 16 patients.CT scan showed no recurrence.And no adrenal insufficiency occurred.One patient had recurrence one year after surgery and two patients turned better after surgery but had recurrence at 3 years and 10 years after surgery.Two patients received contralateral adrenalectomy and cortisol hormone replacement therapy after surgery.Another patient with recurrence refused second surgery.No recurrence was observed in other patients.Four patients were followed up by telephone, and all recovered well after surgery.18 patients had hypertension before surgery and their blood pressure significantly decreased after surgery.Among them 13 cases blood pressure returned to normal range.5 patients had elevated blood glucose before surgery, and 3 patients' blood glucose returned to normal range.Conclusions Unilateral adrenalectomy for Cushing syndrome in patients with ACTH independent bilateral macronodular adrenal hyperplasia is safe and effective.

Objective To provide evidence for the rational use of antibiotics.Methods Analyze on the results of pathogen detec-tion and antibiotic susceptibility tests for the patients in the hospital from January 2013 to December 2013.Results There were 2 111 strains of pathogenic bacteria detected in 2013,among which the Gram-negative bacteria accounted for 75.5%(1 594/2 111). The main species were Klebsiella pneumonia,Escherichia coli,Acinetobacter baumannii,Enterobacter cloacae,Pseudomonas aerugi-nosa,Klebsiella oxytoca.Gram-positive bacteria accounted for for 20.3%(428/2 111),the main species of which were Streptococcus pneumonia,Staphylococcus aureus,Staphylococcus aureus and Enterococcus faecalis.There were 89 strains of fungi,which accoun-ted for 4.2%(89/2 111).The antibiotic susceptibility tests showed that Klebsiella pneumoniae′s drug resistance to 13 kinds of anti-biotics were all less than 25.00%.Escherichia coli,Acinetobacter baumannii,Pseudomonas aeruginosa displayed highly resistance to cephalosporin antibiotics while sensitive to Cefperazone-Sulbactam.The antibiotic resistance of Gram-positive bacteria to macrolide were greater than 70% while that to Vancomycin was 0.0%.Staphylococcus aureus and Staphylococcus epidermidis were highly re-sistant to penicillin.Conclusion The monitoring of bacterial resistance in hospital contributes to the rational use of antibiotics and avoiding the formation and spread of drug-resistant strains.

Objective:To understand the patients'satisfaction on catastrophic medical insurance of New Rural Cooperative Medical Scheme ( NRCMS ) , and provide references for effective management and policy improvement. Methods:According to the principles of representative sampling, a questionnaire survey conducted. 484 patients got compensation for catastrophic insurance in 2013 were surveyed, and information of medical costs was analyzed. Re-sults:The average medical cost accounts for 84. 57% of total household expenditure. Mandatory medical expenditure is still high and economic burden of diseases is heavy. This policy has increased the compensation rate, and the actu-al compensation rate increases 4. 79% in three districts. The average score of patients' attitude toward catastrophic medical insurance is (3.95±1.05) points, 88. 43% of patients continue to participate in medical insurance. Con-clusions and suggestions:Patients' satisfaction on catastrophic medical insurance of NRCMS is high. It is suggested that the existing financing modes should maintain stability in the short term, and the compensatory rate should be im-proved reasonably.
