Objective:To observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

Objective To examine whether Tim-3 plays a protective role in paraquat poisoning induced excessive immune response and tissue damage based on the critical roles of Tim-3 controlling inflammatory response.Methods A paraquat poisoning model was established in wild type and in Tim-3 transgenic C57BL/6 mice by intraperitoneal injection of paraquat (40 mg/kg) .In addition, C57BL/6 mice with paraquat poisoning were injected with Tim-3 soluble protein( sTim-3) or control protein to see the effect of Tim-3 blocking on the progression of paraquat poisoning.Samples were collected at 6 and 24 h after paraquat injection respectively and were examined for tissue damage, cytokine expression and paraquat metabolism.Results After paraquat poisoning, there was significantly attenuated tissue damage in the lungs and kidneys and decreased TNF-α,IL-6 and IL-1 beta expression in the PBMCs or in the serum from Tim-3 transgenic mice compared to wild type mice.The serum concentration of paraquat in Tim-3 transgenic mice was also significantly decreased.However, in sTim-3 treated paraquat poisoning mice, there was significantly increased cytokine expression and tissue damage compared to control protein treated mice.The in vitro data showed that Tim-3 signaling negatively regulated macrophages mediated inflammatory response.Conclusion Tim-3 plays a critical role in maintaining the homeostasis after paraquat poisoning. Further investigation on the regulatory roles of Tim-3 in inflammation will shed new light on the pathogenesis of paraquat poisoning and provide new therapeutic strategies.

Objective To study the epidemiology of hand,foot,and mouth disease (HFMD) and the spectrum of serotypes in the other enterovirus (EV) (non-EV-A71 and non-Coxsaekievirus group A 16,CV-A 16) from 2016 to 2017 in Guangzhou,to provide the basis for its treatment,prevention and control.Methods Enteroviruses universal type,EV-A71 and CV-A16 were detected by real time reverse transeription-polymerase chain reaction in the specimens from HFMD suspected patients from 2016 to 2017.The positive specimens of non-EV-A71 and non-CV-A16 were amplified and sequenced based on 5'-untranslated region (UTR) region.The spectrum of serotypes was analyzed with BLAST in NCBI on the basis of 5'-UTR region.Results A total of 25779 specimens from HFMD patients were collected during 2016-2017,16 300 (63.23 ％) of which were positive.The positive rates of EV-A71,CV-A16,non-EV-A71 and non-CV-A16 were 4.57％ (1 178/25 779),12.70％ (3 274/25 779) and 45.96％ (11 848/25779),respectively.The average positive rate of non-EV-A71 and non-CV-A16 in 2017 was 55.68％,which was higher than that in 2016.Sequence analysis showed that there were 16 genotypes in 95 non-EV-A71 and non-CV-A16 positive specimen,including CV-A6,CV-A10,CV-A4,CV-A2,CV-A8,CV-A12,CV-A9,Coxsakievirus B5 (CV-B5),CV-B2,CV-B4,CV-B3,Echovirus 1 (E1),E16,E30,E2 and E18.CV-A6 (26.32％),and CV-A10 (15.79％) were the most common genotypes,followed by CV-A4 (6.32％)、CV-A8(4.21％),and CV-A2 (4.21％).Conclusions The infection rate of EV-A71 is very low during 2016-2017.From April to July 2016,there is a small peak of CV-A16 infection.The non-EV-A71 and non-CV-A16 enterovirus becomes the main causative agent of HFMD during 2016 to 2017.CV-A6 and CV-A10 are the most prevalent pathogens of non-EV-A71 and non-CV-A16 enterovirus.Research and monitoring of CV-A6,CV-A10 as the main non-EV-A71and non-CV-A16 virus should be strengthened.

Objective To understand the status quo of nutrition working ability in primary medical and health institutions of Chongqing City.Methods Three primary medical institutions were randomly extracted from each of 39 districts and counties of Chongqing City,and Primary Nutrition Service Capacity Survey Form and Nutrition Work Capacity Survey System were adopted to conduct the questionnaire survey.Then the sur-vey results were analyzed.Results A total of 117 primary medical institutions were surveyed,in which 86 in-stitutions(73.50％)undertook the nutritional work.The number of engaging the nutrition full-time work in the units was 0(0,0).Among the nutritional staff,the age in 164 persons was 30-＜40 years old,accounting for 48.38％,180 persons(53.10％)had the primary title,232 persons(68.44％)had the bachelor degree,287 persons(84.66％)had the medical related background,but only 2 persons had the nutritional related profes-sional background.There were 57(48.72％),75(64.10％),77(65.81％)primary medical institutions in carry-ing out the nutrition and health management of pregnant women,children aged 0-6 years old and elderly peo-ple,34 institutions(29.10％)in carrying out nutritional monitoring,and 17 institutions(14.50％)had the clinical nutrition work ability.Compared with the villages and towns,the proportion of urban area primary medical institutions in carrying out the blood routine items in children aged 0-6 years old,hemoglobin,blood routine and urine routine items in elderly people was higher,the number of published popular science works on nutrition was more,and the differences were statistically significant(P＜0.05).Conclusion The nutrition work system of primary medi-cal institutions in Chongqing City is temporarily imperfect,the specialized persons still lack and the nutritional health service level needs to be further strengthened.

Objective:To understand the infection status, epidemiological characteristics and drug resistance of Diarrheagenic Escherichia coli (DEC) in Shanghai and provide evidence for the disease surveillance. Methods:The epidemiological data of diarrhea cases in Shanghai from 2016 to 2022 were collected from Shanghai Diarrhea Comprehensive Surveillance System, and stool samples were collected from the cases for DEC detection. The drug resistance data was obtained from Chinese Pathogen Identification Network. Statistical analysis was conducted by using χ2 and fisher test. Results:In 24 883 diarrhea cases detected during 2016-2022, the DEC positive rate was 9.13% (2 271/24 883), the single DEC positive rate was 8.83% (2 197/24 883) and the mixed DEC positive rate was 0.30% (74/24 883). The main type of DEC was Enterotoxigenic Escherichia coli (ETEC) [4.33% (1 077/24 883)]. The DEC positive rate was highest in people aged ≤5 years 18.48% (22/119). The annual peak of DEC positive rate was observed during July - September [5.91% (1 470/24 883)]. The DEC positive rate were 9.47% (554/5 847) and 9.02% (1 717/19 036) in urban area and in suburbs, respectively, Enteroaggregative Escherichia coli (EAEC) [3.98% (233/5 847)] and ETEC [4.56% (868/19 036)] were mainly detected. From 2016 to 2019, the DEC positive rate was 9.42% (1 821/19 330), while it was 8.10% (450/5 553) from 2020 to 2022, the main DEC types were ETEC (4.87%, 941/19 330) and EAEC (4.70%, 261/5 553). The multi-drug resistance rate was 40.21% (618/1 537). The top three antibiotics with high drug resistance rates were ampicillin [64.74% (995/1 537)], nalidixic acid [58.49% (899/1 537)] and tetracycline [45.09% (693/1 537)]. Conclusions:Compared with 2016- 2019, a decrease in DEC detection rate was observed during 2020-2022, and the main type of DEC detected shifted from ETEC to EAEC. The prevalence of multi-drug resistance was severe. Therefore, it is necessary to further strengthen the surveillance for DEC drug resistance and standardize the use of clinical antibiotics.

OBJECTIVE To evaluate the effect and safety of ciprofol combined with local anesthesia on elderly patients undergoing hemorrhoidectomy. METHODS A total of 108 elderly patients who underwent hemorrhoidectomy at the Department of Proctology， Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from February 2023 to June 2024， were included. The patients were randomly divided into the etomidate group （54 cases） and the ciprofol group （54 cases） based on a computer-generated random sequence. One patient with intraoperative bleeding and one who refused postoperative examination were excluded， resulting in a final total of 106 patients completing this trial （52 in the etomidate group and 54 in the ciprofol group）. The two groups of patients underwent hemorrhoidectomy under local anesthesia with sedative assistance， receiving either etomidate at 0.2 mg/kg or ciprofol at 0.3 mg/kg combined with sufentanil at 0.1 μg/kg. The sedation success rate， induction time， recovery time， operation time and hemodynamic parameters [heart rate （HR）， mean arterial pressure （MAP）， pulse oxygen saturation （SpO2） and respiratory rate （RR）] were observed at baseline （T0）， after successful induction of anesthesia （T1）， 10 minutes after the start of surgery （T2）， and awakening （T3）. Additionally， the levels of oxidative stress markers [malondialdehyde （MDA） and superoxide dismutase （SOD）] were measured at T0， T2 and T3. The occurrence of adverse reactions was also recorded. RESULTS The induction time of the ciprofol group was significantly shorter than that of the etomidate group （P＜0.05）， while the recovery time was significantly longer in the ciprofol group compared to the etomidate group （P＜0.05）. AtT1 and T2， HR， MAP and RR of two groups were significantly lower compared to the same group at T0 （P＜0.05）. However， no significant differences were observed in the hemodynamic parameters at each time point between the two groups （P＞0.05）. At T2 and T3， the MDA levels in both groups were significantly higher than at T0， while the SOD levels were significantly lower than the same group at T0； the ciprofol group showed significantly better outcomes than the etomidate group at the same time points （P＜0.05）. The proportion of patients with intraoperative somatic movements was significantly lower in the ciprofol group compared to the etomidate group （P＜0.05）. CONCLUSIONS When ciprofol is used in elderly patients undergoing hemorrhoidectomy， it demonstrates certain advantages over etomidate in maintaining hemodynamic stability and reducing oxidative stress. Additionally， ciprofol has higher safety.
