Purpose To investigate the clinicopathological features,immunophenotype,molecular changes,differential di-agnosis,treatment and prognosis of the micropapillary subtype of serous borderline tumor(MSBT)in the ovary.Methods The clinical and pathological data of 14 cases of ovarian MSBT.Im-munohistochemical EnVision staining was used to detect the ex-pression of IMP3.BRAF and KRAS mutations were detected by qRT-PCR and Sanger sequencing,respectively.Its clinical and pathological characteristics were analyzed with review of relevant literature.Results The age of the patients ranged from 27 to 56 years,with mean 41.7 years.Nine cases had bilateral ovari-an masses.Preoperative serum CA125 increased in 11 cases.On gross examination,the cut section was cystic and solid with intracystal papillae.Microscopically,all cases showed a papilla-ry structure,with the characteristic elongated micropapillae radi-ating directly from the cyst wall or large unbranched papillae.The length to width ratio of the papillae was greater than 5.The cells covering the papillae were cubic to polygonal.Mild to mod-erate atypia was noted with a range of＞5 mm in the micropapil-lary area.Five cases had microinvasion.Six cases had non-in-vasive peritoneal seeding.Five cases were accompanied by asci-tes,and atypical tumor cells were observed in ascites.Three ca-ses had lymph node involvement.Nine cases had psammoma bodies.Immunohistochemically,the tumor cells were positive for ER,PR,CA125,CK7 and WT-1;p53 was wild type,HER2 and IMP3 were negative,and Ki67 was positive in 5％to 30％.KRAS mutations were detected in 3 of 14 cases,inclu-ding G12C,G12D and Q70(nonsense mutation).No BRAF V600E mutation was detected,and 1 case had BRAF T559I mu-tation.Seven patients underwent radical surgery and 7 patients underwent conservative surgery without special treatment after surgery.Five patients had a history of recurrence,and the fol-low-up time ranged from 1 to 12 years.Conclusion MSBT has special morphology,often bilateral,and is prone to peritoneal implantation and recurrence.It should be distinguished from classical ovarian serous borderline tumor.

Purpose To investigate the expression and po-tential clinical value of heat shock protein 90α(Hsp90α)in co-lon adenocarcinoma.Methods The expression level of Hsp90αin colon adenocarcinoma and its relationship with clinicopatho-logical features,prognosis and immune cell infiltration were ana-lyzed by bioinformatics and immunohistochemistry.The prolifer-ation ability of colon cancer cells before and after Hsp90AA1 knockout was detected by CCK-8 cell proliferation assay and plate cloning assay.Results The bioinformatics tools showed that Hsp90AA1 was abnormally higher in colon cancer tissues than adjacent tissues,and the higher the expression level,the worse the prognosis of patients.The expression of Hsp90AA1 was positively correlated with the infiltration levels of CD4+T cells(Th2),CD8+T cells,myeloid inhibitory cells,Tregs cells,neutrophils,macrophages,M1 macrophages and M2 macropha-ges.Immunohistochemical results showed that the expression of Hsp90α in colon cancer tissues was significantly higher than in its adjacent tissues.The expression of Hsp90α was related to age(P＜0.05),not related to gender,tumor size,location,clini-cal classification,differentiation degree,tumor node metastasis,lympho-vascular invasion,perineural invasion(P＞0.05).The high expression of Hsp90α was an independent risk factor for the prognosis of colon cancer patients.The results of cell experi-ments showed that Hsp90AA1 knockout inhibited the growth and proliferation of colon cancer cells.Conclusion Hsp90α is highly expressed in colon adenocarcinoma,which may be a po-tential molecular marker for poor prognosis of colon adenocarci-noma.

Objective To investigate the effect of Zhuang medicated thread moxibustion on postherpetic neuralgia model rats,and to verify the mechanism of Th1/Th2/Th17 cytokine balance regulation in central nervous system.Methods 50 SD rats were randomly divided into blank group,model group,thread-moxibustion without drugs group,Zhuang medicated thread moxibustion group and pregabalin group,with 10 rats in each group.Except for blank group,the rat model of postherpetic neuralgia was induced by a single intrapitoneal injection of resin-toxin(RTX).After successful modeling,each group was given corresponding treatment for 21 days.The Mechanical Pain Threshold(PWT)and Thermal withdrawal latency(TWL)were detected 3 days before modeling,1,4 and 7 days after modeling,and 3,7,14 and 21 days after intervention.After the intervention,extract spinal cord tissue,Flow cytometry was used to detect changes in the proportion of Th1/Th2/Th17 cells;The mRNA expression levels of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were detected by qPCR;The positive expressions of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were observed by immunohistochemistry.The protein expressions of IFN-γ,IL-2,IL-4,IL-10,IL-17 and IL-22 were detected by Western blot to elucidate the regulation effect of this therapy on the equilibrium mechanism.Results After intrapitoneal injection of resin-toxin,the PWT of rats showed a downward trend,while the TWL showed an upward trend,showing the separation of heat and pain,which was consistent with the clinical manifestations of PHN.After Zhuang medicated thread moxibustion therapy,PWT increased and TWL decreased in PHN rats,which reduced the separation trend of heat and pain.Thread-moxibustion without drugs group,Zhuang medicated thread moxibustion group and pregabalin group can promote Th1 response in the central nervous system(spinal cord),increase the proportion of CD4+IL-2+cells and the contents of IFN-γ and IL-2 in the spinal cord tissue,and up-regulate the expression of IFN-γ and IL-2 mRNA and protein.Meanwhile,Th2 and Th17 responses in the central nervous system were inhibited,and the proportions of CD4+IL-4+and CD4+IL-17A+cells and the contents of IL-4,IL-10,IL-17 and IL-22 in the spinal cord tissue were reduced.The mRNA and protein expressions of IL-4,IL-10,IL-17 and IL-22 were down-regulated.In addition,Zhuang medicated thread moxibustion group and pregabalin group had similar efficacy in correcting Th1/Th2/Th17 lymphocyte imbalance in the central nervous system,and both were better than the Thread-moxibustion without drugs group.Conclusion Zhuang medicated thread moxibustion can improve the separation trend of heat and pain in postherpetic neuralgia rats,which may be achieved by regulating Th1/Th2/Th17 cell balance and related cytokine levels.

ACC oxidase (ACO) is one of the key enzymes that catalyze the synthesis of ethylene. Ethylene is involved in salt stress response in plants, and salt stress seriously affects the yield of peanut. In this study, AhACO genes were cloned and their functions were investigated with the aim to explore the biological function of AhACOs in salt stress response, and to provide genetic resources for the breeding of salt-tolerant varieties of peanut. AhACO1 and AhACO2 were amplified from the cDNA of salt-tolerant peanut mutant M29, respectively, and cloned into the plant expression vector pCAMBIA super1300. The recombinant plasmid was transformed into Huayu22 by pollen tube injection mediated by Agrobacterium tumefaciens. After harvest, the small slice cotyledon was separated from the kernel, and the positive seeds were screened by PCR. The expression of AhACO genes was analyzed by qRT-PCR, and the ethylene release was detected by capillary column gas chromatography. Transgenic seeds were sowed and then irrigated with NaCl solution, and the phenotypic changes of 21-day-seedings were recorded. The results showed that the growth of transgenic plants were better than that of the control group Huayu 22 upon salt stress, and the relative content of chlorophyll SPAD value and net photosynthetic rate (Pn) of transgenic peanuts were higher than those of the control group. In addition, the ethylene production of AhACO1 and AhACO2 transgenic plants were 2.79 and 1.87 times higher than that of control peanut, respectively. These results showed that AhACO1 and AhACO2 could significantly improve the salt stress tolerance of transgenic peanut.

ObjectiveTo analyze the epidemiological characteristics of senile dementia death in Jing’an District from 2016 to 2020， as well as the trends of mortality， standardized mortality， years of life lost （YLL） due to early death， years lived with disability （YLD）， and disability-adjusted life year （DALY）， and to provide scientific basis for the prevention and control of senile dementia. MethodsThe distribution of senile dementia in terms of gender， age， marital status and education level was investigated in the senile dementia death cases from 2016 to 2020 in Jing’an District. The YLL， YLD， DALY and their rates of the residents of Jing’an District from 2016 to 2020 were calculated by using Global Burden of Disease （GBD 2019） research method and results in combination with the corresponding population data. ResultsCompared to those without dementia， deaths with dementia were more likely to be female， more likely to be over 80 years old， less likely to be married， and more likely to have education level under middle school. Among the deaths with dementia， only 27.70% of the primary cause of death was dementia， and the other main causes were cerebrovascular disease， coronary heart disease and diabetes mellitus， which accounted for 25.54%， 17.81% and 7.28%， respectively. There was a significant gender difference in the burden of disease on senile dementia in Jing’an District. Mortality， standardized mortality， YLL， YLD and DALY rates of females were higher than those of males. The burden of disease on senile dementia increased with age. The change trend of mortality and YLL rate from 2016 to 2020 was not statistically significant， while the YLD rate and DALY rate showed an upward trend， which was statistically significant. ConclusionAs the life span of residents in Jing’an District increases and the population aging deepens， the burden of disease on senile dementia is still heavy. This requires extensive attention of the whole society， and active exploration of prevention and control strategies and measures for senile dementia， so as to improve the life quality of patients and reduce the burden of disease.

To present the clinical characteristics and the misdiagnosis rate of acute coronary syndrome manifested primarily as throat discomfort, we conducted a multicentric and retrospective study in the cardiology and otorhinolaryngology departments. Records of patients with primary complaint of throat discomfort, absence of chest pain at onset, and an ultimate diagnosis of acute coronary syndrome, as well as patients with pharyngitis (as controls) were collected from May 2015 to April 2016. The patients' main manifestations were compared. Logistic regression results showed that chest tightness, dyspnea, perspiring, and exertional throat symptoms were significantly associated with acute coronary syndrome, with odds ratios of 8.3 (95% CI 2.2-31.5), 10.9 (95% CI 1.8-66.9), 25.4 (95% CI 3.6-179.9), and 81.2 (95% CI 13.0-506.7). A total of 25 (56.82%) out of 44 acute coronary syndrome patients, who were first admitted to the otorhinolaryngology department, were misdiagnosed, with a 12% (3/25) mortality rate. Throat discomfort can be the principal manifestation of acute coronary syndrome. Such patients exhibit high misdiagnosis and mortality rates. Exertional throat symptoms, chest tightness, perspiring, and dyspnea were important indicators of acute coronary syndrome in patients whose main complaint was throat discomfort. The awareness of this condition will result in prompt diagnosis and reduce morbidity and mortality.

Objective:To estimate the healthy life expectancy (HALE) of registered residents in Jing′an District, Shanghai City.Methods:From June to August in 2017, 14 districts (towns) were selected as the research sites, and 4 159 registered residents were selected as the subjects. The health status data of subjects were collected by using the self-rated health scale, and the health rate of subjects was obtained by using the CHOPIT model. The health rate of residents under 18 years old was replaced by the parameters of 18-year-old group, and Sullivan method was used to calculate the HALE of registered residents in Jing′an District, Shanghai City.Results:The age of 4 159 subjects was (56.46±15.19) years old, ranging from 18 to 98 years old. There were 1 768 males (42.5%). The overall health rate of subjects was 74.96%, of which the health rates of male and female were 76.87% and 72.45% respectively. With the increase of age, the health rate decreased ( Z=265.51, P<0.001), and the health rate of male was higher than that of female (χ2=2 154.54, P<0.001). The HALE of the 0-year-old group was 64.29 years old, in which the male and female were 66.25 and 63.57 years old respectively. Among the 18-year-old group, the HALE was 48.18 years old, with 49.07 years old for male and 47.46 years old for female. The HALE of male was higher than that of female in all age groups. With the increase of age, the HALE decreased gradually. Conclusion:There are significant sex and age differences in HALE in Jing′an District, Shanghai City. The health issue of female and older people should be given more attention.
