Paclitaxel is a kind of monomer diterpene compound extracted from the taxus chinensis, which has good anti-cancer activity. It is widely used in the treatment of breast cancer, ovarian cancer, lung cancer and other cancers. It also has been listed as the first-line chemotherapy medicine on breast cancer and ovarian cancer. However, the drug resistance is the main obstacle to clinical application similar to other kinds of chemotherapy medicine. The low toxicity and high efficient traditional medicine monomer, represented by curcumin, has become the research focus on reversing paclitaxel resistance. This article summarized the research on synergy between curcumin and paclitaxel, with a purpose to provide references for finding clinical assistant chemotherapeutic medicine.

Objective To investigate the antibiotic resistance trend of commonly used antibiotics of Helicobacter pylori (H.pylori) in Huzhou district,and to summarize the efficacy of eradication in related digestive diseases.Methods In year 2009,2013,2014 and 2015,8 139 gastric mucosa samples of patients undergoing gastroendoscopy examination were collected and H.pylori strains were isolated and cultured.The situation of resistance to levofloxacin,clarithromycin,metronidazole,amoxicillin,tetracycline and furazolidone was analyzed.The infection and antibiotics resistance of H.pylori were analyzed in 11 digestive diseases including functional dyspepsia,chronic gastritis,acute gastritis,duodenitis,gastric ulcer,duodenal ulcer,gastrointestinal dysfunction,gastric cancer,residual gastritis,reflux esophagitis and gastric lymphoma.The eradication schemes and eradication rate of H.pylori was reviewed in six digestive diseases including functional dyspepsia,chronic gastritis,duodenitis,gastric ulcer,duodenal ulcer and reflux esophagitis.Fisher's exact test was performed to compare the differences among the groups.Results A total of 3 263 H.pylori strains were obtained and the infection rate of H.pylori was 40.09％ (3 263/8 139).The H.pylori infection rates of 11 digestive diseases were from 0 to 57.89％,and which was high in duodenal ulcer,gastric ulcer,duodenitis,chronic gastritis and functional dyspepsia (57.89％,726/1 254;49.83％,301/604;42.91％,118/275;37.45％,1 518/4 053 and 36.78％,146/397;respectively).The results of single antibiotic resistance analysis in six digestive diseases needed or planed for H.pylori eradication indicated that resistance rate of H.pylori to levofloxacin and clarithromycin reached 23.09％ (663/2 871) and 17.87％ (513/2 871),respectively.The resistance rate tolevofloxacin dramatically increased from 5.03％ (8/159) in 2009 to 28.24％ (586/2 075) in 2015;the resistance rate to clarithromycin increased from 12.58％ (20/159) in 2009 to 21.78％ (452/2 075) in 2015;meanwhile,the resistance rate of H.pylori to metronidazole was nearly 100.00％.However,the resistance rates to amoxicillin,tetracycline and tetracycline were all zero.The results of double antibiotic resistance analysis in six digestive diseases needed or planed for H.pylori eradication indicated that the rate of both levofloxacin and clarithromycin resistance was 7.73 ％ (222/2 871).The double antibiotic resistance rate of levofloxacin and clarithromycin in different diseases fluctuated between 4.82 ％ and 10.96 ％.Totally 1 479patients of six digestive diseases were treated with quadruple therapy,and 1 363 patients were followed up after eradication therapy,with the eradication rate of 85.99％ (1 172/1 363).Conclusions In Huzhou district,for six common digestive diseases needed or planed for H.pylori eradication,any combination of two drugs in all three drugs including amoxicillin,tetracycline and furazolidone is the first choice for treatment.Only when patients are allergic to penicillin or furazolidone and tetracycline can not be obtained,will levofloxacin and clarithromycin be chosen.A high eradication rate can be achieved by choosing eradication schemes according to the results of H.pylori drug sensitivity test in local region.

OBJECTIVETo describe trends of changes in blood lead levels in children aged 1 - 6 years during the time period before and after introducing lead free gasoline in Shanghai 1997 and 1999.

METHODSBlood lead levels of 1 969 children aged 1 - 6 years were determined by a sampling survey in five districts of Shanghai in August and September, 1997. Blood lead levels of the same population were re-determined by the same method from April to June in 1998 and from August to September in 1999. Filter paper blood lead test was carried out monthly using the filter paper blood lead proficiency testing program of Centers for Disease Control in the United States. The results from blood lead samples were under acceptable ranges during the study.

RESULTSThe geometric means of blood lead levels were 83 microgram/L in 1997, 80 microgram/L in 1998 and 76 microgram/L in 1999, respectively. The prevalence rates of childhood lead poisoning (blood lead level was equal or more than 100 microgram/L) were 37.8% in 1997, 25.7% in 1998 and 24.8% in 1999. The amounts of decrease on average blood lead levels in the five districts between 1997 and 1999 were 10 microgram/L, 11 microgram/L, 6 microgram/L, 4 microgram/L and 2 microgram/L, respectively.

CONCLUSIONLead poisoning is a preventable disease. The average levels of lead in young children in Shanghai decreased significantly after the introduction of lead free gasoline to Shanghai. Lead emissions from vehicles running on leaded gasoline was one of the important contributors to increase the children's blood lead levels in Shanghai. Lead poisoning is not evenly distributed among children in Shanghai, resulting in the different levels of decline.

Objective:To study the correlation between circulating tumor cells (CTC) and the degree of pathological invasion, recurrence and metastasis of urothelial carcinoma, and so to explore the clinical value of CTC detection in bladder cancer.Methods:A total of 142 patients with urothelial carcinoma in Huadong Hospital Affiliated to Fudan University were enrolled as cancer group from July 2016 to January 2018. According to the degree of tumor invasion, cancer group was divided into the non-muscle-invasive group (49 cases) and the muscle-invasive group(93 cases). In addition, 52 patients with benign urinary tract lesions admitted were selected as the benign group and 56 patients with non-urinary tract diseases and non-tumor as the control group. A total of 3.2 ml of venous anticoagulant blood from each subject was collected. CTC was enriched by negative enrichment using the magnetic beads coated with monoclonal antibody Cluster 45 of differentiation (CD45) to capture and remove white blood cells, and identified by chromosome 8 probe(CEP8) fluorescence in situ hybridization (FISH) technique. CD45-/4′,6′-diamidino-2-phenylindole+/CEP8>2(CD45-/DAPI+/CEP8>2) cells were judged as CTC. SPSS22.0 statistical software was used for statistical analysis.Results:≥2 CTCs/3.2 ml in blood was set as cutoff value. CTC positive rates in bladder cancer group, benign group and control group were 70.42%(100/142), 28.85%(15/52) and 8.93%(5/56), respectively, and there was a significant difference (χ 2=70.496, P=0.000). There was a statistically difference ( U=2 863.5, P=0.011) in the mean count of CTC(2 CTCs/3.2 ml vs 4 CTCs/3.2 ml) between the two groups. The proportion of≥5 CTCs/3.2 ml in the muscle-invasive group was 40.86% (38/93), which was significantly higher than that in the non-muscle-invasive group, 18.37% (9/49) (χ 2=7.330, P=0.007). Cystoscope follow-up of 65 patients treated with transurethral resection of the bladder tumor showed that the recurrence and metastasis rate in patients with≥5 CTCs/3.2 ml was as high as 47.62% (10/21), compared with 11.36% (5/44) of patients with<5 CTCs/3.2 ml (χ 2=10.530, P=0.001). Among 59 patients undergoing radical cystectomy, no significant difference was found in tumor diameter >3 cm, positive surgical margins and positive lymph nodes among all groups according to CTC negative or positive and CTC number ( P>0.05). But the recurrence and metastasis rate of patients with ≥5 CTCs/3.2 ml (59.10%) was significantly higher than that of patients with <5 CTCs/3.2 ml (6/30)(χ 2=8.364, P=0.004). Conclusion:The number of CTC increased with the deepening of tumor invasion; Tumor recurrence and metastasis increased significantly in the patients with ≥5/3.2 ml CTCs in blood.
