As a classic cerebral revascularization procedure, carotid endarterectomy (CEA) has been widely used in the treatment of high-grade extracranial carotid artery stenosis. In recent years, carotid artery stenting (CAS) has a trend to replace CEA gradually. A large number of clinical studies have found that in addtion to perioperative complications, carotid restenosis after CEA and CAS also has important influence on the prognosis of patients. This article reviews the current status of diagnosis and treatment of restenosis after CEA and CAS.

Objective:To explore the protective effect of the water-soluble total flavonoids from Isodon lophanthoides var.gerardia-nus (Benth.) H.Hara on LO2 cells damage.Methods:The cytotoxicity was evaluated by MTT cell viability determination to confirm the concentration range .Hepatocyte damage model was established by H 2 O2 treatment.After the oxidative stress hepatocyte was coin-cubated with WSTF at different concentrations for various times , the protective effect of WSTF on H 2 O2-induced hepatocyte damage was evaluated by MTT cell viability determination and the content determination of ALT , AST and MDA in cell supernatant .The inhibition of WSTF against H 2 O2-induced LO2 cells apoptosis was evaluated by the quantitative determination of Rhodamine 123 fluorescence and intracellular ROS.Results:The LO2 cells injured by 0.3 mmol· L-1 H2 O2 treatment for 4 h were used as the hepatocyte damage model.The concentration range of WSTF was 0.0312-0.125 mg· ml-1.WSTF could inhibit H2O2-induced injury in LO2 cells and obviously reduce ALT, AST and MDA.Moreover, WSTF could reverse mitochondrial membrane potential depolarization and decrease the amount of intracellular ROS .Conclusion:WSTF exhibits notable protective and curative effects on hepatocyte damage in vitro.

Objective　To explore the role of the allelic deletion and mutation of FHIT gene on the carcinogenesis and development of lung cancer. Methods　The allelic alterations of FHIT gene and microsatellites D3S1300, D3S1312,D3S1313 were detected in 35 cancer samples of NSCLC, their corresponding normal tissues, and 4 lung cancer cell lines, and 10 lung tissues of benign pulmonary lesions as control by PCR-SSCP and DNA sequence. Results　Loss of heterozygosity (LOH) affecting at least one locus of FHIT gene was observed in 22 out of 35 tumors, with a LOH rate of 62.86％. LOH of FHIT gene in squamous cell carcinoma (88.24％) was significantly higher than that in adenocarcinoma (38.89％) (P＜0.01). The LOH rate of FHIT gene in smoking patients (76.19％) was also significantly higher than that in non-smoking patients (42.86％)(P＜0.05).No significant relationship was found among the LOH of FHIT and cell differentiation, P-TNM stages, size of primary tumor, location of cancer and age of the patients (P＞0.05). LOH of FHIT was also detected in Lewis lung cancer and A549 cell lines. Mutation of microsatellite D3S1312 was observed in 4 lung cancer tissues. DNA sequence showed that CT mutation occurred in the 87 codon of microsatellite D3S1312. Conclusion　The alteration of FHIT gene is mainly allelic loss and the frequency of allelic mutation is rare. FHIT gene alterations preferentially occur in squamous cell carcinoma patients and smokers, and FHIT gene may be a candidate molecular target of carcinogenesis in tobacco smoker. Allelic deletion of FHIT gene might be an early molecular event in smoking-related lung cancer.

OBJECTIVETo study the prevalence of cerebral palsy (here in after referred to CP) in children aged 1 - 6 in Guangxi, China, and its epidemiologic characteristics and relevant risk factors.

METHODSInvestigations on the prevalence and etiology of CP in children at ages of 1 - 6 were conducted in Nanning, Hengxian and Qinzhou of Guangxi from June to December in 1998, with a cluster sampling.

RESULTSTotally, 150 806 children aged 1 - 6 were investigated in Nanning, Hengxian and Qinzhou of Guangxi, with 89 418 boys and 61 388 girls. Among them, 193 children were diagnosed as CP, with a prevalence rate of 1.28 per thousand, higher in boys (136 cases, 1.52 per thousand ) than in girls (57 cases, 0.93 per thousand ), with statistical significance (chi(2) = 9.536 7, P = 0.02). Logistic regression analysis showed that risk factors for CP were children who could not cry after birth (neonatal asphyxia), Apgar score less than eight, delivery at lower level of maternity hospital, number of mother's gravidity, no prenatal checks for mothers, and taking antipyretics and preserved food with salt during pregnancy.

CONCLUSIONSPrevalence of CP in children of Guangxi was at a lower level in comparison with that in other areas at home and abroad, which, maybe, was related with the lower neonatal survival and higher infant mortality.

Objective To investigate the emotional memory changes in patients with thalamic infarction on different laterals and explore the impact of different emotional valence pictures on the thalamic infarction(TI) patients' memory.Methods 28 patients with thalamic infarction (TI group)and 28 patients who were hospitalized without TI during the same period (control group) were given emotional memory test,a test where they use their emotional memory to evaluate and recognize pictures with different emotional valence,including positive,neutral,and negative valence.Results (1) At the stage of evaluating emotional images,there were no significant difference between patients with TI and control group in positive evaluation (P＞0.05).Compared with control group (neutral(12.96±1.62),negative(13.57±1.37),respectively),neutral and negative recognition scores for emotional pictures of patients with TI (neutral (10.79±2.07),negative (10.96±2.05),respectively) were decreased significantly (positive t =-4.5 and negative t=-5.6,both P＜0.05).(2)At the stage of emotional images memorizing tests,TI group's total scores on re-accessing total emotional pictures were significantly lower than those in control group ((36.14 ± 3.24) vs(41.89 ± 3.43) respectively)) (t=-6.44,P＜0.05).Compared with control group (positive (14.04± 1.29),neutral (13.68±1.56)),patients with TI (positive (10.93± 1.96),neutral(11.25± 1.67)) were decreased significantly in the emotional pictures memorizing tests (t=-7.00,5.61,P＜0.05).But there were no difference in negative stimulus between the two groups (P＞0.05).(3)The score of emotional pictures recognition in patients with LTI (34.43 ± 3.48) were decreased significantly than that in patients with RTI (37.86± 1.83) (t =3.26,P＜ 0.05).The score in recognizing neutral valence images in patients with LTI(10.43± 1.55) were significantly decreased than those in RTI (12.07± 1.38) (t=2.95,P＜0.05).Conclusion Patients with TI may rely on different neural mechanisms to affect the different valence of the emotional memory loop process.The emotional memory impairment in patients with TI at different sides is different.The left thalamus has a greater influence on memory.

Objective:To investigate the relationship between the dose of preoperative neoadjuvant radiotherapy and the pathologic complete response (pCR) rate in patients with locally advanced squamous cell esophageal cancer (ESCC).Methods:Clinical data of 116 patients with ESCC who received neoadjuvant chemoradiotherapy followed by esophagectomy in our cancer center from July 2017 to December 2019 were retrospectively analyzed. The radiation doses were divided into 2 ranges based on Grays (Gy) received: 40-45 Gy and 45 Gy or more.Results:The overall pCR rate was 38. 8%(45/116). pCR was observed in 35 out of 80(44%) patients treated with 40-45 Gy and 10 of 36(28%) patients treated with 45 Gy or more. The pCR rate did not significantly differ between two groups [(40-45 Gy) vs.( ≥ 45 Gy), P=0.105)]. Conclusions:Preoperative neoadjuvant radiotherapy with a higher dose (≥ 45 Gy) fails to increase the pCR rate in patients with locally advanced ESCC. Prospective randomized trials are required to determine the optimal dose of preoperative adjuvant radiotherapy.
