Objective The objective of this study was to investigate the clinicopathological features and rational treatment of primary fallopian tube cancer(PFTC).Methods The clinical and pathological data of 39 patients with primary fallopian tube cancer from January 2006 to July 2016 in Beijing Tongren Hospital of Capital University were retrospectively analyzed.Results There were 39 cases of undifferentiated carcinoma,including 1 case of undifferentiated and transitional cell carcinoma,37 cases of undifferentiated adenocarcinoma,or 29 cases of simple adenocarcinoma and 10 cases of mixed type.Among them,7 cases were treated with clear cell carcinoma,endometriosis in 2 cases,combined with transitional cell carcinoma in 1 case.Extra-pelvic metastases were the most common site of the omentum with 17 cases.The preoperative test CA125 was increased in 13 cases and 38 patients received postoperative chemotherapy.The 5-year overall survival rate of 39 patients was 51.3%.Univariate analysis showed that postoperative pathologic stage(Ⅰ~Ⅱ vs.Ⅲ,P<0.001),intraoperative residual lesion size(P<0.001),omentum metastasis(P<0.001),ovarian metastasis(P=0.034),retroperitoneal lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were associated with prognosis,while age(P=0.310)and pathological grade(P=0.663)were not associated with prognosis.Multivariate analysis showed that the number of patients with postoperative lymph node metastasis(P=0.018)and preoperative CA125 elevation(P=0.002)were correlated with prognosis(HR=1.202,95% CI:2.354~63.290,P=0.003) and pathological stage(HR=3.810,95% CI:1.202~12.079,P=0.023).They were associated with prognosis as independent prognostic factors.Conclusion Tumor pathologic staging and omentum metastasis are important prognostic factors influencing the prognosis of patients with primary fallopian tube cancer.Early diagnosis and complete operation can improve the prognosis of patients.

OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.

METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.

RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.

CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.

The gene encoding the phosphatidylserine synthase in Escherichia coli K12 Sgal-(ExPASy P23830) was amplified by PCR. After DNA sequence analysis, it was inserted into the inducible expressive shuttle vector pBES of Bacillus subtilis, which was constructed in the lab, and the recombinant plasmid pBES-pss was transformed into competent cells of the Bacillus subtilis strain DB104. The positive transformant DB104 (pBES-pss) was grown on Bacillus subtilis common fermentation medium, which contained 30?g/ml kanamycin. After 2 hours cultivation, sucrose was added and increased to the final concentration of 2% for induction and this phosphatidylserine synthase was secreted into the medium. The result of SDS-PAGE showed that the molecular weight of the protein was 52kDa and the result of enzyme coupling colorimetric method showed that the enzyme activity was 1.50U/ml. The recombinant Bacillus subtilis has increased the yield of phosphatidylserine synthase which will be used for industrial biosynthesis of phosphatidylserine.

The infection process of Exserohilum monoceras and alteration of cellar ultrastructure in infected barnyardgrass were observed by using scanning electron microscope and transmission electron microscope. The observation showed that the hypha began to form from the basal point of the conidia 8 hours after inoculation (HAI) and then penetrated barn-yardgrass leaves through stornata 13 HAI. The infection process finished from 24 to 26 HAI. After infected, cell membranes of the host were dramatically changed; starch particles disappeared in chloroplasts and lots of phenolic compounds occurred in the infected cells.

Methods　According to the requirements of the Final Evaluation Plan of the National Plan for the Prevention and Control of Hydatid Disease and Other Major Parasitic Diseases (2016-2020), a retrospective survey method was adopted to collect relevant data on the implementation and safeguard measures of the prevention and control of major parasitic diseases, and population infection status in Hubei Province in 2016-2019. Results From 2016 to 2019, We carried out 2 920 992 person times of publicity and education, 209 times of prevention and control technology training, 7 680 person times of business training, with an average of 52 sessions and 1 920 person times per year. We have allocated 3.445 2 million yuan for the prevention and control of parasitic diseases, including 1.722 2 million Yuan froom provincial government, to achieved full coverage of safe drinking water in rural areas under the current national standards, and 7.687 9 million harmless toilets have been built in rural areas. From 2016 to 2019, we carried out 39 658 person times of monitoring and disease investigation, the infection rate of human liver fluke was 0, and the infection rate of soil transmitted nematode was 0.42%. While the annual infection rates varied, there was no statistically significant difference in infection rate between years (χ2＝2.276, P>0.05), but there were statistically significant differences in the infection rates between various soil nematodes (χ2=112.807, P<0.01). From 2016 to 2019, a total of 5 393 people were detected at 17 monitoring points, with the serum positive rate of 3.93% for paragonimiasis, there was a statistically significant difference in serological positive rate between years (χ2=146.011, P<0.01); a total of 738 stream crabs were collected, and the infection rate of intermediate host was 16.26%, wtih a statistically significant difference in the infection rate of stream crabs between years (χ2=49.731, P<0.01). Conclusions　From 2016 to 2019, we adhered to the prevention and control strategy of "prevention first, prevention and control combined", implemented comprehensively various prevention and control measures, and achieved remarkable results in Hubei Province. The key parasitic diseases have been in a low epidemic situation, meeting the requirements of the prevention and control objectives. But the transmission risk still exists, the next step is to continue to strengthen security and monitoring and consolidate the achievements of prevention and control.

Objective To propose an Alzheimer's disease(AD)classification method based on deep learning and multimodal physiological data.Methods Multimodal data from the Alzheimer's Disease Neuroimaging Initiative(ADNI)database of AD patients,early mild cognitive impairment(EMCI)patients,late mild cognitive impairment(LMCI)patients and normal cognition(NC)subjects were selected.Three networks were used for AD classification,of which an improved New_ResNet50 network extracted the features of MRI images of the subject's brain to realize AD classification,a 3D-Unet-Attention network segmented the hippocampus images and implemented residual network-based AD classification,and a multi-layer perception(MLP)network carried out AD classification based on patient physiological data and hippocampus size,and the final classification results were determined with the voting method.Comparison analyses were performed on the classification results by the improved New_ResNet50 network model,3D-Unet-Attention network model or traditional network models,and the improved New_ResNet50 network model,3D-Unet-Attention network model and MLP network model were all compared with the fusion network model involving in the three networks model above.Results The improved New_ResNet50 network model and 3D-Unet-Attention network model both had the classification accuracy enhanced when compared with the traditional network models,and the fusion network model had a classification accuracy of 97.99％for AD patients and control normal,which was higher by 1.51％,1.51％and 14.62％than those by the improved New_ResNet50 network model,3D-Unet-Attention network model and MLP network model respectively.Conclusion The classification method proposed behaves well for AD classification,and can be used for auxiliary diagnosis of AD.[Chinese Medical Equipment Journal,2023,44(11):1-8]

Objective To investigate and analyze consistency in attitudes toward advance directive and life sustaining treatments between cancer patients and their family members.Methods Totally 242 pairs of cancer patients and family members were involved in the research through convenience sampling from two tertiary hospitals.We investigated consistency in attitudes toward advance directive and life sustaining treatments between cancer patients and their family members using questionnaire of attitudes toward advance directive.Results After explanation of advance directive,51.65％ of cancer patients would like to make advance directive.Most of the family members(89.26％) said they would like to follow patients' wishes if they made advance directive.The consistency in attitudes toward advance directive between cancer patients and their family members were "willing" accounting 48.35％,and "not willing" accounting for 1.65％,with weak consistency(Kappa value was 0.05,P＞0.05).The consistency in attitudes toward life sustaining treatments between cancer patients and their family members were "willing" accounting for 16.94％～38.84％,"not willing" accounting for 1.65％～4.96％,and "never considered" accounting for 9.92％～17.77％,with weak consistency(Kappa value was 0.09-0.18,P＜0.05).Conclusion Cancer patients and their family members show positive attitudes toward advance directive without too many differences.Family members' choices on life sustaining treatments cannot fully represent patients' wishes.

Huperzine A is a potent,reversible,and blood-brain barrier permeable acetylcholinesterase irhibitor.The aim of this study was to compare the pharmacokinetics,tolerability,and bioavailability of two formulations with the established reference formulation of huperzine A in a fasting,healthy Chinese male population.This was a randomized,single-dose,3-period,6-sequence crossover study.The plasma concentrations of huperzine A were determined by liquid chromatography tandem mass spectrometry.Tolerability was assessed based on subject interview,vital sign monitoring,physical examination,and routine blood and urine tests.The mean (SD) pharmacokinetic parameters of the reference drug were Cmax,1.550 (0.528) ng/mL;t1/2,12.092 (1.898) h;AUC0-72h,17.550 (3.794) ng.h/mL.Those of the test formulation A and test formulation B were Cmax,1.412 (0.467),1.521 (0.608) ng/mL;t1/2,12.073 (2.068),12.271 (1.678) h;AUC0-72h,15.286 (3.434) ng.h/mL,15.673 (3.586) ng.h/mL.The 90％ confidence intervals for the AUC0-72h and Cmax were between 0.80 and 1.25.No adverse events were reported by the subjects or found with results of clinical laboratory test.The test and reference products met the regulatory criteria for bioequivalence in these fasting,healthy Chinese male volunteers.All three formulations appeared to be well tolerated.

OBJECTIVE: To study the correlation of Mycoplasma pneumoniae DNA (MP-DNA) replication level in throat swab and bronchoalveolar lavage fluid (BALF) with disease severity in children with severe Mycoplasma pneumoniae pneumonia (SMPP). METHODS: A total of 44 children with SMPP who underwent bronchoalveolar lavage were enrolled as subjects. The serum levels of cytokines and MP-DNA replication times in throat swab were measured in the acute stage and the recovery stage, and the levels of interleukin (IL)-8 and MP-DNA replication times in BALF were measured in the acute stage. According to whether mechanical ventilation was needed for respiratory failure, the children were divided into a mechanical ventilation group (n=19) and a non-mechanical ventilation group (n=25), and the two groups were compared in MP-DNA replication times in BALF. RESULTS: For the children with SMPP, serum levels of C-reactive protein, erythrocyte sedimentation rate, lactate dehydrogenase, IL-1, IL-6, IL-8, and IL-18 in the acute stage were significantly higher than those in the recovery stage (P<0.05). In the acute stage, MP-DNA replication times in throat swab were positively correlated with those in BALF (r=0.613, P<0.05), and MP-DNA replication times in BALF were positively correlated with IL-18 levels in peripheral blood and BALF (r=0.613 and 0.41 respectively, P<0.05). Compared with the non-mechanical ventilation group, the mechanical ventilation group had significantly higher MP-DNA replication times in BALF, a significantly longer duration of systemic hormone treatment, significantly higher serum levels of lactate dehydrogenase and IL-18, and significantly higher white blood cell count and IL-18 level in BALF (P<0.05). CONCLUSIONS In children with SMPP, MP-DNA replication level in throat swab and BALF can be used as a reference index for the assessment of disease severity.

Objective · To investigate the prevalence of smoking and awareness of smoking hazards in a community-based elderly population in Changning District, Shanghai. Methods · A total of 1809 subjects were randomly selected from 18 communities based on the chronic non-communicable diseases cohort in an elderly population aged 65 and over in Changning District, Shanghai. Information on smoking status, health condition and awareness of smoking hazards were obtained through face to face interviews. Chi-square tests and non-conditional Logistic regression analyses were used to evaluate the risk factors of the awareness of smoking hazards and current smoking status. Results · The overall prevalence of current smoking was 15.6% among the investigated elderly population. Smoking prevalence was significantly higher in men than that in women (30.0% vs 2.1%, P=0.000). Also, it was higher in the men aged 65-69 than that in those aged 70 and over (34.3% vs 20.4%, P=0.000). The participants with middle school education had the highest prevalence (19.1%) in the population. Overall, the proportion of participants who knew "smoking causes heart disease" "smoking causes stroke"and "smoking causes cancer" was 45.1%, 43.3% and 64.4%, respectively. Among the participants, 36.4% knew all the three smoking hazards. With the confounders such as age and gender being adjusted, current smoking behavior was associated with the participants' awareness of smoking hazards (OR=0.74,P=0.000). Conclusion · Currently, the awareness of smoking hazards is generally low in Shanghai elderly population, especially in those with lower education level and current smoking behavior. More targeted educational interventions are necessary in specific population.
