Objective:The recent therapeutic effects and safety profile of pemetrexed plus cisplatin as first-line chemotherapy in advanced lung adenocarcinoma were evaluated. Methods:A total of 41 chemotherapy-naive locally advanced or metastatic non-small cell lung cancer patients, who were diagnosed with adenocarcinoma by pathological examination, were included. All patients received 500 mg/m2 pemetrexed on day 1. A total dose of 75 mg/m2 cisplatin was divided into three daily doses administered over 3 d. Treat-ments were repeated every three weeks. The therapeutic efficiency and safety profile were evaluated every two treatment cycles. Re-sults:All 41 patients were eligible for the evaluation of therapeutic efficiency. Seventeen patients showed partial response, 20 patients showed stable disease, and four patients showed disease progression. The overall response rate (ORR) was 41.5%and the disease con-trol rate (DCR) was 90.3%. Subgroup analysis showed that the ORR in males was significantly higher than that in females (63.1%vs. 22.7%, P=0.009). The median progression-free survival of all patients was 11.0 months, whereas the median overall survival was 12.6 months. The intracranial lesions of six patients with brain metastases were well controlled after chemotherapy and palliative whole brain radiotherapy. The ORR and DCR for these patients were 83.3%and 100.0%, respectively. In terms of safety, only 4.8%of the pa-tients showed gradesⅢandⅣneutropenia, nausea, or vomiting. Conclusion:Pemetrexed plus cisplatin is an effective and well-tolerat-ed regimen as first-line therapy for patients with lung adenocarcinoma. According to subgroup analysis, efficacy in males was signifi-cantly better than that in females. Good efficacy was observed in patients with brain metastases treated with chemotherapy and pallia-tive whole brain radiotherapy. No additional adverse effects were observed.

BACKGROUND: Logistic analysis of multi-ordered response-variable is used to probe into from another view the interrelationship between lead content in fetus faeces and neurobehavioral development under exposure to low-level lead in uterus.OBJECTIVE: To probe into multi-factors of neurobehavioral development in neonates and the sensibility.DESIGN: The total score of neurobehavior in neonates was taken as dependent variable and 24 indexes were as independent variables, such as induced factors, lead in umbilicus blood and lead in fetus faeces in questionnaire. Logistic progressive regression of multi-ordered response-variables was used in analysis and corresponding factors were screened at level of P=0.10.SETTING: Wuhan University of Science and Technology, Laboratory Room of Occupation Disease and Epidemic disease in Tongji Medical College of Huazhong University of Science and Technology and Occupation Hospital of China First Metallurgical Construction General Company.PARTICIPANTS: Totally 103 full-month borne and healthy neonates were randomized in Department of Gynecology of one occupation hospital in Qingshan District of New-type Industry Area of Huanhan City from January to October 1999 as the objects. The relatives agreed with topic research and questionnaire investigation and they provided neonatal faeces and received neonatal tests on time.off the umbilicus and preserved in freezing in refrigerator at -4 ℃. The faeces in 24 hours after birth was collected and the lead contents of umbilicus blood and faeces were assayed with graphite furnace atomic absorpBehavioral Neurological Assessment (NBNA) was used in examination on the 3rd day after delivery. Simultaneously, the self-designed questionnaire was adopted in the investigation for parturients. The questionnaire involved other possible factors of neonatal neurobehavioral development, including dependent variables, concerning to states of family, society, environment and health that affected neurological development in neonates and lead contents in umbilicus blood and faeces. Scores of neonatal neurobehavior were taken as response variables. Finally, the corresponding factors were screened.MAIN OUTCOME MEASURES: To screen the factors of neurobehavioral development of neonates.RESULTS: Totally 103 cases entered result analysis. Six factors were selected in the model, named pregnant weeks, the month of drug administration in pregnancy, hemoglobin, emotions in pregnancy, lead level in fetus faeces and drug administration.CONCLUSION: Neonatal neurobehavioral development was related to multiple factors. Good nutrient in pregnancy, long pregnant weeks and good emotions in pregnancy benefit neurobehavioral development of neonates. Drug administration during pregnancy is disadvantageous in neonatal neurobehavioral development, especially the medication at the early phase of pregnancy. The increased lead content in neonatal faeces does not benefit neonatal neurobehavioral development.

BACKGROUND: In the past, a lot of researches used one-time lead level in umbilical cord blood at birth for investigations,however, one-time lead level in umbilical cord blood at birth can not represent lead caused cumu lative injury to neonatal nervous system during the whole period of preg nancy. Lead in meconium is mainly from digestive juice secreted by fetal alimentary tract, exfoliative epithelia from neonatal intestinal tract and am niotic fluid and sebum cutaneum swallowed by fetus, which is excreted from the very start of pregnancy to 24 hours after birth of neonates and re flects the lead deposit in neonatal intestinal tract during the whole period of pregnancy. OBJECTIVE: To explore the relationship between neurobehavioral devel opment in neonates with intrauterine exposure to lead at low level and the lead level in umbilical cord blood (CBPb) and meconium (MPb). DESIGN: Take lead levels in umbilical cord blood and meconium as neonatal intrauterine exposure indicators and scores of neonatal neurobe havioral development as effect indicators, and descriptive analysis is used to evaluate the correlativity. SETTING: Wuhan University of Science and Technology; Laboratory of Occupation Disease and Epidemiology, Tongji Medical College, Huazhong University of Science and Technology; Wuhan First Metallurgical Con struction Company Hospital for Workers and Staff. PARTICIPANTS: A total of 103 cases of full-term and healthy neonates were selected as objects of observation. The neonates were born in Depart ment of Gynecology and Obstetrics, Wuhan First Metallurgical Constrction Company Hospital, Qingshan District of New Industrial District of Wuhan from January to October 1999. Their parents were agreed to participate in the study and filled in the questionnaire, and provided neonatal meconium and performed neonatal tests on schedule. METHODS: ① Collection and assay of sample: 5 mL umbilical cord blood were collected and reserved in refrigerator at -4 ℃. Meconium with in 24 hours after birth, with dry weight between 5 to 10 g was collected, the lead levels in umbilical cord blood and meconium were assayed with the method of graphite furnace atomic absorption spectroscopy. ② Group ing: The neonates were divided into two groups with high and low-exposure to lead based on the cutoff value of CBPb of 0.483 μmol/L and MPb of 127.78 mg/kg. ③ Neonatal neurobehavioral development examination: Neonatal neurobehavioral development examination method was used for examination 3 days before delivery. Meanwhile, self-designed questionnaire was used to conduct a survey in puerperas. MAIN OUTCOME MEASURES: ① Lead levels in neonatal umbilical cord blood and meconium. ② Scores of neurobehavioral development of neonates with different lead levels of umbilical cord blood and meconium. RESULTS: All the 103 cases of neonates entered results analysis. ①There was significant difference only in scores of neonatal behavioral neurological assessment (NBNA) and biological visual and auditory orientation reaction (BVAOR)between groups with high and low-exposure to lead in umbilical cord blood (P ＜ 0.05). However, there was no rank correlativity between lead level in umbilical cord blood and scores of NBNA,non-biological auditory orientation reaction (NBAOR), non-biological visual orientation reaction (NBVOR) and biological visual and auditory orientation reaction (NBVOR). ②here was significant difference in scores of NBNA,NBAOR, NBVOR and BVAOR between groups with high and low-exposure to lead in meconium (P ＜ 0.05-0.01). The lead level in meconium clearly correlated reversely with scores of NBNA, NBVOR and BVAOR.CONCLUSION: Lead level in meconium is more sensitively related to the scores of neonatal neurobehavioral development, which could be used as indicator for lead deposit in the fetal body during the period of pregnancy.

Objective To evaluate the feasibility and safety of prostatic artery embolization (PAE)via transradial approach in treating prostatic hyperplasia.Methods The clinical data of 18 patients with prostatic hyperplasia,who received C-arm CT-guided PAE via left or right radial artery access,were retrospectively analyzed.The following indexes were recorded:arterial spasm and injury of upper limbs,incidence of puncture point bleeding,postoperative radial artery pulse and congestion,blood supply and nerve injury of fingers,the surgical success rate,incidence of perioperative cerebral vascular complications,operation time,radiation dose and clinical curative effect.Results Among the 18 patients,PAE via left radial artery access was employed in 14,and PAE via right radial artery access was performed in 4.Bilateral PAE was carried out in 16 patients,and only unilateral PAE was able to be successfully accomplished in 2 patients as the prostatic artery opening of the other side was tortuous with stenosis.After PAE,decreased radial pulse was observed in one patient and ultrasound examination revealed decreased blood flow.The operation time ranged from 96 min to 245 min.The radiation dose received by the patient varied from 2435 mGy to 4958 mGy with a mean of (3342±156) mGy,which was not significantly different from the radiation dose received by the patients who underwent PAE via femoral artery access during the same study period (P=0.1167).Conclusion In treating prostatic hyperplasia,PAE by using transradial approach is clinically safe and technically feasible.

Objective To prepare and identify rabbit anti-cyclin dependent kinase 6 (CDK6) antibody. Methods The recombinant pET21a (+)/CDK6 was successfully constructed, then the recombinant plasmid was transformed into E.coli BL21 (DE3) competent cells and was induced by isopropyl-β-D-thiogalactopyranoside (IPTG) for protein expression, which was detected by SDS-PAGE and Western blot analysis. The expressed protein was purified by nickel-chelating nitrilotriacetic acid (Ni-NTA) agarose and then analyzed by SDS-PAGE. Japanese white rabbits were immunized with purified CDK6 protein for many times every two weeks. The blood was collected at 0, 2, 4 and 6 weeks after immunization, and serum was separated from blood. The titer was detected by indirect ELISA. Western blot analysis, immunofluorescence assay and immunohistochemistry were employed to determine the specificity. Results High purity CDK6 protein and high specificity of rabbit anti-CDK6 antibody were successfully prepared. The titer of CDK6 rabbit serum antibody reached 1:30 000 after immunization, which could specifically recognize the CDK6 protein expressed in cervical cancer cell line and cervical cancer tissues. Conclusion The high titer and specificity of rabbit anti-CDK6 antibody is successfully prepared.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.
