Objective To explore the relationship between serum adiponectin (APN) concentration and insulin resistance(IR) in elderly pregnancy patients(GDM) with gestational diabetes mellitus.Methods Data of 120 cases of elderly pregnancy patients with gestational diabetes mellitus admitted from Jan.2011 to Dec.2016 were retrospective analyzed.The relationship between serum APN concentration and IR was assayed.Healthy subjects and normal pregnancy patients in our Department were taken as the control.Results The concentration of APN was lower while the CysC,BNP,IGF1,IGF2 and IGFIR were higher in elderly pregnancy patients with gestational diabetes mellitus than those in the control group with a significant difference (P＜0.05).At the same time,Spearman analysis results showed that the serum APN was negatively related with IR while CysC,BNP,IGF1,IGF2 and IGFIR were positively related with IR (P＜0.05).Conclusion Theserumconcentrationofadiponectin and visfatin were negatively related with insulin resistance in elderly pregnancy patients with GDM.

Objective To investigate the phenotypes and genotypes of extended -spectrum β-lacta-mases (ESBLs) and AmpC β-lactamases produced by cefoxitin-resistant Shigella strains isolated from Zhe-jiang province and the virulence of those strains .Methods Kirby-Bauer antibiotic testing was performed to screen cefoxitin-resistant strains from 356 Shigella isolates.The serotypes of the cefoxitin-resistant strains were detected .The phenotypes of ESBLs and AmpC β-lactamases from cefoxitin-resistant strains were detec-ted by ESBLs confirmatory test and AmpC-three-dimensional test ,respectively .The genotypes of ESBLs and AmpC β-lactamases were analyzed by PCR and sequence analysis .The virulence genes ( virA, ial, iapH, set1A, set1B and sen) in the cefoxitin-resistant strains were screened by PCR .Results Eight cefoxitin-re-sistant strains were identified from 356 Shigella isolates.Among them,six strains were identified as Shigella flexneri (S.fleaneri) strain (four F2a,one F2b and one F2c),and the rest were identified as Shigella sonnie (S.sonnei) strain.Among all eight cefoxitin-resistant strains,five strains showed positive results for ESBLs confirmatory test and two strains showed positive results for AmpC-three-dimensional test .Seven out of the eight strains harbor ESBLs genes (CTX-M-14,15,57 and/or OXA-30),two of which were positive for AmpC genes (DHA-1 and CMY-2).Five out of the eight cefoxitin-resistant strains carried all of the six tested viru-lence genes,while the other three strains possessed four virulence genes except for set1A and set1B.The two strains producing both ESBLs and AmpC β-lactamases were susceptible only to imipenem .Conclusion ESBLs positive isolates are prevalent strains of cefoxitin-resistant Shigella with potential high virulence .Some of them also produce AmpC β-lactamases ,and the DHA-1 type of AmpCβ-lactamase is identified for the first time in China .

Abstract] Objective To study the roles of IL-12 and IL-23 in the development of protective im-munity and pathological changes during chlamydial urogenital infection.Methods C57BL/6J wild type (wt) mice and mice deficient in IL-12p35 (IL-12p35 KO) or IL-12p40 (IL-12p40 KO)were inoculated in-travaginally with 1×104 IFU of live Chlamydia muridarum ( C.muridarum) organisms.Half mice of each group were reinfected on day 114 after primary infection.Vaginal swabs were taken every 3 or 4 days to mo-nitor live organism shedding.The mice were sacrificed after 114 or 143 days of primary infection and the va-ginal tract and kidney samples were collected for pathological analysis.The numbers of chlamydial inclusion bodies and bacteria in kidney homogenates were titrated after 100 days of primary infection.Results The infection time courses of mice deficient in either IL-12p35 or IL-12p40 were similar after primary infection, but were prolonged as compared with the wild type mice.All mice regardless of genotypes developed severe pathological damages in upper genital tracts with no significant difference among different groups.Almost all IL-12p40 KO mice and some IL-12p35 KO mice showed pathological changes in kidney samples.No obvious abnormality was observed in any of the kidneys from wild type mice.Neither the age-matched IL-12p35 KO nor IL-12p40 KO mice developed any gross pathological changes in kidney in the absence of chlamydial in-fection.C.muridarum inclusions were detected in kidney samples with gross pathological damages from IL-12p35 KO mice and IL-12p40 KO mice.No inclusions were ever detected in kidneys from the wild type mice.The numbers of chlamydial inclusions in the IL-12p40 KO mice were much higher than those of the IL-12p35 KO mice.Live bacteria were detected in mice deficient in either IL-12p35 or IL-12p40, but not in the wild type mice.No significant difference with the number of live bacteria was found between IL-12p35 KO mice and IL-12p40 KO mice.Conclusion IL-12 and IL-23 could inhibit the spread of C.muridarum in-fection from genital tract to kidney.The deficiency of IL-12 or IL-23 might relate to the renal lesions induced by Chlamydia infection.

Objective To investigate the roles of SENP1 in regulation of biological characteristics of NK cells.Methods Lentivirus-mediated-Senp1-small-hairpinRNA (shRNA) transduction was applied to NK92 cells.The expression of SENP1 in NK92 cells was determined by real-time PCR and Western blot.The proliferation of NK92 cells was detected by CCK-8 assay.The apoptosis of NK92 cells was determined by Annexin Ⅴ and PI labeling.The cytotoxicity of NK92 cells against K562 cells was evaluated by luciferase reporter assay.Results Treatment of NK92 cells with IL-21 resulted in SENP1 upregulation.Lentivirus mediated SENP1 knockdown reduced proliferation and increased apoptosis in NK-92 cells,but SENP1 inhibition had slight impact on the cytotoxic ability of NK92 cells to kill K562 cells.Conclusion SENP1 mediates the regulatory effect of IL-21 on the proliferation and survival of NK92 cells.

Objective: To research the anti-inflammatory and anti-allergic effects of Qifangbimin particle.Methods: The anti-inflammatory effects were observed by the methods of xylene-induced ear-swelling in mice and cotton-ball induced granuloma in rats.The anti-allergic effects were evaluated by the method of passive skin allergy model in rats and ear-heterogeneous passive skin allergy model in mice.Results: In the treatment groups with Qifangbimin particle, the swelling degree of ear edema induced by dimethylbenzene in mice was significantly suppressed when compared with that in the control groups (P<0.01 or 0.05) , however, the particle had no significantly inhibitory effect on granulation tissue hyperplasia induced by cotton-ball in rats.The Qifangbimin particle groups obviously decreased the absorbance value of locus coeruleus on rats' back (P<0.01 or 0.05), and Qifangbimin particle at high dose significantly reduced the absorbance value of locus coeruleus of auricle in mice (P<0.01 or 0.05).Conclusion: Qifangbimin particle has significant anti-inflammatory and anti-allergic effects.

A survey on professional knowledge levels was conducted from April to October 2019 among 388 general practitioners (GPs) from 46 community health service centers and 30 township health centers of 6 provinces selected by stratified random sampling method. The overall knowledge test score was 31.82—84.09(56.94±9.19) points, and the pass rate was 36.3% (141/388). There were significant differences in test scores among participants with different types of work units, regions, provinces, marital status, educational background, professional titles, types of employment, length of service, and training status (all P<0.05). Multivariate regression analysis showed that educational background ( B=-2.835), professional title ( B=-8.867), and participation in professional course training ( B=2.214) were the influencing factors of knowledge level (all P<0.05). The pass rates in knowledge of prevention/health management (13.7%, 53/388) and policies and regulations (12.1%, 47/388) were low. The results show that the levels of professional knowledge among GPs working in grassroots health institutions are relatively low, and suggest that continuing education should be strengthened to improve the professional knowledge level of GPs in primary care institutions, particularly, knowledge of health policies and regulations, disease prevention and health management.

Objective To establish a simple animal model of cough variant asthma(CVA)through sensitizing Brown-Norway(BN)rats with ovalbumin(OVA). Methods A total of 36 BN rats were randomly divided into three groups, including the normal control group,the model control group and the montelukast group. BN rats in the model group and the montelukast group were intraperitoneally administered with 2.0 mg of OVA and 100 mg of Al(OH)3,and the same volume of sterile saline was given to the normal group by intraperitoneal injection. Boosting was carried out by intraperitoneal administration with 0.01 mg of OVA and 100 mg of Al(OH)33 weeks later,and the rats in the normal group were injected with the same dose of physiological saline. Three weeks later,the actively sensitized BN rats were challenged with aerosolized OVA for 7 times on alternative days,and the rats in the normal group were treated with sterile saline instead of OVA. At the same time, the montelukast group was given 1.3 mg/kg of montelukast 30 minutes before atomization by intragastric administration once a day for 2 weeks,and the normal group and the model group were given the same volume of water. The tests of cough sensitivity to capsaicin and bronchial responsiveness were performed 24 h after the last administration. Results Compared with the normal group, the times of coughing(P< 0.01)and the lung resistance(RL)(P< 0.05)in the model group were significantly increased,while the lung compliance(Cdyn)was significantly decreased(P< 0.05). There was a significant difference(P < 0.05)in the times of coughing caused by capsaicin between the model group and the montelukast group. Compared with the model group,RLin the montelukast group was decreased significantly(P< 0.05), and Cdynwas increased significantly(P< 0.05). Conclusions This rat model of CVA is similar to a variety of clinical features of CVA and is easy to operate. Thus it can be used as an effective animal model of CVA.

OBJECTIVE: To explore the genetic characteristics of a child with Focal segmental glomerulosclerosis and neurodevelopmental syndrome (FSGSNEDS). METHODS: A child with FSGSNEDS who had visited Shengli Oilfield Central Hospital on September 15, 2019 was selected as the study subject. Clinical data of the child was collected, and trio-whole exome sequencing (trio-WES), Sanger sequencing, chromosomal karyotyping analysis, and copy number variation sequencing (CNV-seq) were used to analyze the child and his parents. RESULTS: The child, a 3-year-old boy, had manifested developmental delay, nephrotic syndrome, and epilepsy. Trio-WES and Sanger sequencing showed that he has carried a heterozygous c.1375C＞T (p.Q459*) variant of the TRIM8 gene, for which both his parents were of the wild type. Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic. No abnormality was found in the chromosomal karyotyping and CNV-seq results of the child and his parents. CONCLUSION The child was diagnosed with FSGSNEDS, for which the c.1375C＞T variant of the TRIM8 gene may be accountable.

Background: At present, clinical dilemma remains to be solved in terms of therapy-choices for specific locally advanced cervical cancer (LACC) patients: 1) Although concurrent chemoradiotherapy (CCRT) is recommended as the first choice for them, many patients, influenced by the Chinese culture, prefer to choose radical surgery (RS) as their primary treatment. The difference between the 2 therapies in improving patient prognosis is still unknown. 2) Laparoscopy has been questioned since the noted Laparoscopic Approach to Cervical Cancer trial. Nevertheless, clinical research on laparoscopic surgery under the strict tumor-free principle is still underway globally, therefore whether laparoscopic surgery can be used for specific LACC is also an urgent issue to be explored. Methods A multi-center, randomized controlled study is designed to investigate the effect of different treatment strategies on the prognosis and quality of life (QoL) in patients with specific locally LACC. A total of 402 patients will be enrolled over a period of 3 years. Eligible patients will be randomized (3:1) to either RS group or CCRT group. Patients assigned to RS group will be randomized (1:2) to the abdominal RS group or laparoscopic RS group. All patients will then be followed-up for 5 years. The primary end point is the 2-year progression-free survival (PFS). The secondary end points include 5-year PFS, 2-year overall survival (OS), 5-year OS, adverse events caused by RS or CCRT and QoL.
