Objective To explore the potential clinic value of NSE and S-100 in the serum as early diagnosis in the Bilirubin Encephalopathy(BE)of newborns.Methods 46 neborns were choosed as group A with TSB≥342μmol/L;48 with TSB(256-342)μmol/L as group B;and 30 full term deliveries newborns as normal control group C.Their TSB,NSE and S-100 in the serum were measured.Meanwhile,the BAEP scores were carried out.Results The concentrations of NSE,S-100 and the BAEP scores in newborns of group A and B had significant differences as compared with group C (P <0.05 ).Correlation analysis showed that there was a significant positive correlation between serum NSE,S-100 protein and TSB(P <0.05),while there was a negative correlation between serum NSE, S-100 protein and BAEP scores(P <0.05).Conclusion Serum NSE and S-100 protein can use as early diagnosis targets for the the Bilirubin Encephalopathy(BE)of newborns clinically.

[ ABSTRACT] AIM: To study the autophagy of prostate cancer PC-3 cells induced by CD147 in vitro.ME-THODS:Themethod of amino acid starvation to induce autophagy was used.The expression of CD147 was detected by Western blotting.To study the functional effects of CD147 on autophagy in prostate cancer PC-3 cells, the down-regulation of CD147 expression was induced by the technique of RNAi.The conversion of autophagic marker protein LC3-I to LC3-II was determined by Western blotting.The cell death after starvation-induced autophagy was analyzed by trypan blue exclu-sion assay.RESULTS:The CD147 expression gradually increased in starvation-induced autophagy.The down-regulation of CD147 significantly increased the expression of autophagy-related protein LC3-II compared with control group.Mean-while, the cell death rates increased from (19.3 ±3.1)%and (22.3 ±3.5)%in control groups to (38.4 ±3.1)%in si-lencing the expression of CD147 in the PC-3 cells (P<0.05).CONCLUSION:CD147 inhibits starvation-induced auto-phgy and autophagy death in the prostate cancer PC-3 cells.

Objective To compare the clinical efficacy and the adverse reaction of transcatheter arteri-al chemoembolization( TACE)alone and combined with stereotactic body radiation therapy( SBRT)in patients with primary hepatic carcinoma by a Meta-analysis. Methods PubMed,Cochrane Library,EMBase,Ovid, MEDLIN,CNKI,CBMdisc,VIP and Wanfang were searched to identify the controlled clinical trials of TACE and SBRT for primary hepatic carcinoma. The obtained data were analyzed using Review Manager version 5. 2 provided by Cochrane Collaboration. To analysis the short-term effect of TACE alone or combined with SBRT, the rate of local tumor control and the difference of one,two,three and five-year survival rate. Results A total of 1 143 patients from 10 controlled clinical trials were involved according to the inclusion criteria. The Meta-analysis showed that TACE and SBRT group significantly increased the short-term effective rate,the rate of local tumor control,l-,2-,3-and 5-year overall survival rates(RR=1. 43,95%CI:1. 32-1. 56,P﹤0. 000 01;RR=2. 09,95%CI:1. 63-2. 69,P﹤0. 000 01;RR=1. 31,95%CI:1. 21-1. 42,P﹤0. 000 01;RR=1. 46, 95%CI:1. 23-1. 72,P﹤0. 000 01;RR=1. 76,95%CI:1. 14-2. 71,P=0. 01;RR=2. 29,95%CI:1. 22-4. 32, P=0. 01). There was no statistically significant difference between the two groups on adverse events such as leucopenia(RR=0.97,P =0. 61),thrombocytopenia(RR =0. 99,P =0.85),hemoglobin decrease(RR =0. 95,P=0. 63),nausea and vomiting(RR=1. 00,P=0. 98),liver function damage(RR=0. 98,P=0. 87). Conclusion Compared with TACE,TACE combined with SBRT can increase the short-term effective rate,the rate of local tumor control,the 1-,2-,3-and 5-year overall survival time of the patients,and does not increase the incidence of adverse reaction. However high-quality trials with large sample sizes are still needed to verify the long-term efficacy and safety.

Objective: To estimate the epidemic threshold and graded intensity thresholds of influenza in Zhejiang Province from 2012 to 2023 using the moving epidemic method (MEM), and evaluate the intensity of influenza epidemics, so as to provide the reference for influenza prevention and control in Zhejiang Province. Methods: The positive rates of influenza virus per week during the influenza epidemic seasons (from 40th week to 20th week of the following year) in Zhejiang Province from 2012 to 2022 were collected through the Chinese Influenza Surveillance Information System. A MEM model was established and optimized using cross-validation. The maximum accumulated rates percentage was used to divide the epidemic into pre-epidemic, epidemic, and post-epidemic periods, and to estimate the epidemic thresholds and graded intensity thresholds. The intensity of influenza epidemics in Zhejiang Province during the 2022-2023 epidemic season were assessed. Results: The positive rates of influenza virus in five epidemic seasons from 2012 to 2022 were included in the model. The MEM model performed best when the parameter δ was set to 1.5, with a sensitivity of 0.971, a specificity of 0.745, and a Youden's index of 0.716. According to the model analysis, the epidemic beginning and ending thresholds of influenza in Zhejiang Province during the 2022-2023 epidemic season were 19.32% and 10.92%, respectively, and the medium, high, and extremely high intensity thresholds were 48.65%, 63.49%, and 68.47%, respectively. During 2022-2023, the influenza epidemic was in the pre-epidemic period from the 40th week in 2022 to the 7th week in 2023; the epidemic period was from the 8th to the 18th week, the epidemic intensity was low in the 8th week and increased to a high level in the 9th week, and reached to a extremely high level from the 10th to the 13th week, then fell to the high and the medium level in the 14th week and 15th week, respectively, and fell to a low level from the 16th to the 18th week; the influenza epidemic entered the post-epidemic period since the 19th week. Conclusion MEM could be applied for evaluation of influenza epidemic intensity, providing the reference for early identification and taking graded preventive and control measures.

Objective To analyze the long?term efficacy of intensity?modulated radiotherapy (IMRT) with or without chemotherapy in treatment of 454 patients with nasopharyngeal carcinoma (NPC) and its influencing factors. Methods A retrospective analysis was performed on the clinical data of 454 patients with non?metastatic NPC who received IMRT with or without chemotherapy in our center from 2007 to 2012. Prescribed doses of 69. 96?73. 92 Gy in 33 fractions, 69. 96 Gy in 33 fractions, 60. 06 Gy in 33 fractions, and 50. 96 Gy in 28 fractions were applied to nasopharyngeal gross tumor volume, cervical metastatic lymph nodes, high?risk drainage area, and low?risk drainage area, respectively. In all patients, 438 received induction chemotherapy, 420 concurrent chemotherapy, and 216 adjuvant chemotherapy, most of which were based on cisplatin and taxol. The Kaplan?Meier method was used for calculating survival rates and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox model was used for the multivariate prognostic analysis. Results The 3?year sample size was 210. The 3?year overall survival ( OS ) , local recurrence?free survival, nodal relapse?free survival, progression?free survival, and distant metastasis?free survival ( DMFS) rates were 88. 1%, 91. 0%, 90. 7%, 80. 5%, and 85. 1%, respectively. Age, T stage, and N stage were influencing factors for the OS rate ( P=0. 011;P=0. 005;P=0. 033);T stage and N stage were influencing factors for the disease progression?free survival ( P=0. 017;P=0. 005) and DMFS ( P=0. 012;P=0. 019) . The grade≥3 acute and late adverse reactions included hematological toxicity , oral mucositis , xerostomia , dysphagia , and brain injury . Conclusions IMRT promotes the long?term survival rates in patients with NPC. The distant metastasis is the major reason for treatment failure. The adverse reactions induced by IMRT combined with chemotherapy are tolerable.

A 57-year-old man was admitted to hospital with diarrhea for 10 months and dizziness for 4 months. The patient had 1-2 liters watery stool per day, without pyogenic blood or abnormality in gastroenteroscopy examination. The level of hemoglobin and albumin was generally normal, and fasting test was positive. At the same time, he was accompanied with hyperalgesia of lower limbs and orthostatic hypotension. After the discussion of multiple disciplinary teams, the patient was diagnosed with amyloidosis by sural nerve biopsy, myocardial MRI, and the assays of urine immunoelectrophoresis and serum free light chain. Light chain amyloidosis was confirmed after excluded the diagnosis of familial amyloidosis. The patient was improved after courses of chemotherapy with melphalan and dexamethasone.

Objective To investigate the relationship between polymorphisms of N-acetyltransferase 2(NAT2)genes and anti-tuberculosis drug induced hepatic-injury(ADIH).Methods A 1:1 matched case-control study was conducted.One hundred and six cases fulfilling the criteria of ADIH were selected as ADIH group from the patients who received anti-tuberculosis therapy.whereas those patients without any hepatic inj ury related elinical symptoms during three months of follow-up period were selected as control.The genetic polymorphisms of the loci,NAT2481C/T,NAT2-590G/A and NAT2-857G/A,were determined by polymerase chain reaction and restriction fragment length polymorphism technique(PCR-RFLP)in patients who received antituberculosis therapy.The major environmental factors and genotypes were analyzed by univariate and multivariate conditional Logistic analyses.Results The T,AA allele frequencies of NAT2-481C/T,NAT2-590G/A and NAT2-857G/A were 7.5%,28.8%and 17.9%respectively in ADIH group,and 6.6%,18.9%and 17.5%,respectively in the control group.Univariate analysis demonstrated that the frequency of NAT2 slow acetylation genotype in ADIH group was significantly higher than that in control group with a crude OR(95%CI)of 2.250(1.140-4.441).Among 6 potential risk factors,i.e.education level,occupation,body mass index(BMI),smoking,drinking and the type of tuberculosis,the low BMI and drinking were two risk factors for ADIH.In multivariate analysis,ADIH remained associated with acetylation genotype after adjusting for BMI and drinking status.The adjusted OR(95%CI)was 2.246(1.086-4.644).Conclusion NAT2 slow acetylation genotype may be associated with the occurrence of ADIH.

Estrogen is an important hormone secreted by the female reproductive system. Its main function is associated with reproduction, growth and development. Studies have shown that estrogen has biological functions such as regulating vasoconstriction, antioxidant stress, anti-inflammatory and neuroprotection, and also affects brain structure and network. Studies have shown that estrogen is closely associated with the occurrence and development of white matter hyperintensities (WMHs). This article reviews the relationship between estrogen and menopausal hormone replacement therapy and WMHs, and their possible pathophysiological mechanisms.

Carotid atherosclerosis (CAS) is closely associated with the decline of cognitive function in the elderly, which can lead to persistent or progressive cognitive function and neurological dysfunction. Vascular cognitive impairment (VCI) is considered to be an intervenable disease. Studies have shown that CAS is one of the main causes of VCI. Further study on the relationship between CAS and VCI will help to better prevention and treatment of VCI.
