Objective: To observe the clinical efficacy of acupuncture and moxibustion for functional dyspepsia (FD) due to Yang deficiency of the spleen and stomach.Methods: A total of 90 patients meeting the inclusion criteria of FD due to Yang deficiency of the spleen and stomach were randomized into an acupuncture-moxibustion group, an electroacupuncture (EA) group, and a mosapride group by the random number table method, with 30 cases in each group. The mosapride group was treated with mosapride citrate dispersible tablets. The EA group was treated with EA treatment. The acupuncture-moxibustion group was treated with additional moxibustion therapy based on the treatment in the EA group. All three groups took 10 d as one treatment course and 2 courses in total, with a 2-day interval between two courses. The traditional Chinese medicine (TCM) symptoms score, functional digestive disorder quality of life questionnaire (FDDQL) score, oral-colon transit time (OCTT), and serum glucagon-like peptide-1 (GLP-1) level was compared before and after treatment among the three groups. And the clinical efficacy was evaluated.Results: The total effective rate in the acupuncture-moxibustion group was 96.7％, which was higher than 86.7％ in the EA group and 73.3％ in the mosapride group, and the total effective rate in the EA group was higher than that in the mosapride group; the inter-group differences were all statistically significant (P<0.05). After treatment, the TCM symptom score in the three groups was lower than that before treatment (P<0.05), and the FDDQL score was higher than that before treatment (P<0.05). The change after treatment in the TCM symptom score in the acupuncture- moxibustion group and the EA group was more significant than that in the mosapride group, and the change in the acupuncture-moxibustion group was more significant than that in the EA group; the inter-group differences were statistically significant (P<0.05). The change after treatment in the FDDQL score in the acupuncture-moxibustion group and the EA group was greater than that in the mosapride group, and the change in the acupuncture-moxibustion group was larger than that in the EA group; the inter-group differences were all statistically significant (P<0.05). After treatment, the OCTT in all three groups was lower than that before treatment (P<0.05), and the serum GLP-1 level was higher than that before treatment (P<0.05); the change after treatment in the OCTT in the acupuncture-moxibustion group and the EA group was more significant than that in the mosapride group, and the change in the acupuncture- moxibustion group was more significant than that in the EA group; the inter-group differences were statistically significant (P<0.05). The change after treatment in the serum GLP-1 level in the acupuncture-moxibustion group and the EA group was greater than that in the mosapride group, and the change in the acupuncture-moxibustion group was larger than that in the EA group; the inter-group differences were statistically significant (P<0.05).Conclusion: Acupuncture and moxibustion can improve the clinical symptoms in patients with FD and enhance their quality of life, producing better effects than EA or mosapride alone. Shortening gastrointestinal movement time and increasing gastrointestinal hormone levels may be its mechanism.

Objective:To investigate the training status of robotic-assisted surgery nurses in hospitals with robotic-assisted surgery system in China, and to provide reference for the training and management of robotic-assisted surgery nurses.Methods:From August to December in 2021, hospitals with robotic-assisted surgery system in China were surveyed by a self-designed questionnaire distributed online.Results:The participants in the survey of 111 hospitals in 30 provinces, cities, autonomous regions and municipalities directly under the central government, nurses cooperated with robotic-assisted surgery exist the phenomenon of their own training was up to 96.40% (107/111) of hospital, 47.75% (53/111) of the hospital said the current training content also need to add other aspects of the course. Training duration of theoretical courses was 0-13 (2.86 ± 3.03) periods arranged by hospitals, and the training duration of practical courses was 1-60 (8.38 ± 9.91) d. 35.14% (39/111) of hospitals set up regular assessment after training, and the assessment cycle of them was 1-12 (4.08 ± 3.31) months. Many hospitals put forward suggestions on strengthening English training and attaching importance to team cooperation and so on.Conclusions:In our country, Robotic-assisted surgery nurses′ training has turned to that training themselves in operating rooms, the training time, form, content and other aspects have no uniform standard, strict admittance, standardization of specialist training , these are questions need to solve.

The patients in the observation group was taken folic acid combined with vitamin , the control group only was given vitamins, in all patients on admission and at discharge on the plasma levels of Hcy, D-two dimer, fibrinogen, three glycerol, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol level, the effect of folic acid combined with the vitamin was observed. Results No significant differences between the two groups before treatment, plasma Hcy levels (P>0.05) in different ways, the observation group after treatment, the plasma Hcy levels were significantly lower than the control group , with significant difference ( P<0 . 05 ) . Two groups by different ways of treatment, the observation group was best accounted for 70% (35/50), the excellent and good rate was as high as 98% (49/50), significantly higher than the control group 44% (22/50) and 74% (37/50), with significant difference (P<0.05). On two groups of different ways of treatment of cerebral was stroke recurrence and score in patients with SIAS were compared, the recurrence rate of the observation group was lower than the control group, with significant difference (P<0.05), the SIAS score was significantly higher than that of the control group, with significant difference (P<0.05). Conclusion For the patients with stroke, should the use of folic acid combine with vitamin two level of prevention. The combine uses of folic acid and vitamin , can effectively reduce the incidence of stroke and recurrence rate.

Objective:To explore the establishment and application of ovarian cancer organoids.Methods:Fresh ovarian tumor tissues, obtaining from patients underwent surgery in the First Affiliated Hospital of Nanjing Medical University between October 2021 and March 2022, were collected, enzymatic degraded, digested, and embedded into matrigel to establish organoids. A total of 32 ovarian cancer samples were collected. Hematoxylin eosin (HE) staining and immunofluorescence (IF) procedure were used to verify the morphological structure of organoids and their expression of molecular markers. 3D cyto-live or dead assay was used to detecte the live or dead cells in organoids. Carboplatin with a concentration ranging from 5 to 80 μmol/L (5, 10, 20, 40, 80 μmol/L) was added to organoids to calculate the 50% inhibitory concentration (IC 50) in different organoids. Results:(1) Organoids from a total of 32 patients were established, of which 18 cases could be passaged stably in the long term in vitro, while 14 could be passaged in the short time. The average amplification time of long-term passage in vitro was over 3 months, and the longest reached 9 months. (2) In HE staining, significant nuclei atypia and local micropapillary structures were observed in organoids. IF staining revealed that ovarian cancer organoids expressed molecular markers similar to primary tumor tissues, such as Pan cytokeratin (Pan-CK), p53, paired box gene 8 (PAX8), and Wilms tumor gene 1 (WT1). (3) In 3D cyto-live or dead assay, a large number of apoptotic cells were observed inside and around the organoids after added carboplatin. The sensitivity to carboplatin varied in 18 organoids could amplify in the long term, with an average IC 50 of (29.5±15.8) μmol/L. Moreover, IC 50 values of 4 organoids derived from patients received neoadjuvant chemotherapy were much higher than the 14 organoids which did not received neoadjuvant chemotherapy [(48.7±11.3) μmol/L vs (24.0±12.1) μmol/L; t=3.429, P=0.022]. Conclusions:Organoids recapitulate ovarian cancers in vitro and could be stably passaged. Organoids derived from patients received neoadjuvant chemotherapy have higher resistance to carboplatin.

Objective To explore the interaction between family history of diabetes and hyperlipidemia on the risk of diabetes in population with normotension.Methods A multistage stratified probability random sampling was conducted to select a representative sample of urban residents aged 20-74 years in Harbin.A total of 376 diabetes patients with normotension and 3 692 residents with normal blood pressure,normal fasting glucose,and normal 2 hours glucose from OGTT were surveyed.The interaction was evaluated by using crossover analysis and additive model.Results Multivariate logistic regression analysis indicated that there was a possible additive interaction between family history of diabetes and hyperlipidemia on the risk of diabetes.The relative excess risk due to the interaction,the attributable proportion due to the interaction,and the synergy index were 1.97 (95％CI:-0.32-4.26),0.30 (95％CI:0.03-0.57),and 1.54 (95％CI:0.96-2.47),respectively.There were significant combination effects between family history of diabetes and high both total cholesterol and triglyceride,isolated high total cholesterol,and isolated high triglyceride levels;the ORs were 10.55 (95％CI:5.62-19.80),7.81 (95％CI:3.65-16.71) and 5.13 (95％CI:3.22-8.16),respectively.Conclusion There might be synergistic effect between family history of diabetes and hyperlipidemia on the risk of diabetes in population with normotension.

Objective The objective of this study was to investigate the relationship between the methylation of phosphodies-terase 4C(PDE4C)gene in peripheral blood leukocytes,and its interaction with environmental factors and the pathogenesis of breast cancer. Methods A case-control study was conducted to select 402 cases of breast cancer and 470 cancer-free controls from Octo-ber 2010 to December 2014. The specific DNA methylation-modified quantitative PCR method was used to detect the methylation of PDE4C gene. The use of crossover analysis and multivariate logistic regression was used to analyze the relationship between the level of gene methylation and its interaction with environmental factors and the pathogenesis of breast cancer. Results PDE4C methylation was not found to be significantly associated with the onset of breast cancer. High-frequency/high-intake of whole grains,vegetables, onion-based plants,poultry,milk,and regular exercise could reduce the risk of breast cancer;high-frequency/high-intake of pork, irregular menstrual cycle,and a high psychological stress index could increase the risk of breast cancer. PDE4C hypermethylation had a significant combining effect with edible onion-producing plants greater than 3 times/week,with an OR of 0. 373(95% CI:0. 208~0. 668,P=0. 001). Conclusion Hypermethylation of PDE4C is not an independent risk factor for breast cancer,and its combination with environmental factors affects the risk of breast cancer.

Objective The aim of this study was to investigate the relationship between STAT1,STAT3 gene promoter CpG island methylation status and prognosis of patients with colorectal cancer(CRC)and the prognostic factors of CRC patients. Methods The cohort study was conducted to biosamples and follow up 239 patients with primary colorectal cancer pathologically diagnosed in Cancer Hospital of Harbin Medical University(Tumor Hospital). The methylation status of STAT1,STAT3 gene promoter CpG island was analyzed by methylation specific high-resolution melting curve(MS-HRM). Results The survival rates of 239 patients with colorectal cancer at 1 year,3 years and 5 years were 94. 90% ,86. 00% and 67. 20% ,respectively. The methylation status of STAT1 and STAT3 genes was not associated with postoperative survival in colorectal cancer patients( STAT1:HR=0. 85,95% CI:0. 55 ~1. 30,P=0. 44;STAT3:HR=0. 75,95% CI:0. 36~1. 58,P=0. 45). Dukes stage(HR=1. 31,95% CI:1. 14~1. 51,P<0. 01)and intraoperative intestinal stapler use(HR=1. 98,95% CI:1. 25 ~3. 14,P<0. 01) were important factors affecting the prognosis of colorectal cancer patients. The risk of death in patients with stage D and Dukes was significantly higher than that in stages A and B (HR=1. 31,95% CI:1. 14~1. 51,P<0. 01). Intestinal anastomosis was used during operation. The patient′s prognosis was better than that of patients without an intestinal stapler. However,gender,age,tumor location,gross tumor type,histological classification and postoperative chemotherapy were not associated with the prognosis of colorectal cancer. Conclusion Dukes stage is an independent factor affecting the prognosis of colorectal cancer. The prognosis of patients with intestinal stapler is better than that of non-users. The methylation status of STAT1 and STAT3 in peripheral blood is not a biomarkers for the prognosis of patients with colorectal cancer.

Objective:To describe the COVID-19 epidemic and its characteristics in Heilongjiang province, and provide evidence for the further prevention and control of COVID-19 in the province.Methods:The information of COVID-19 cases and clusters were collected from national notifiable disease report system and management information system for reporting public health emergencies of China CDC. The Software’s of Excel 2010 and SPSS 23.0 were applied for data cleaning and statistical analysis on the population, time and area distributions of COVID-19 cases.Results:On January 22, 2020, the first confirmed case of COVID-19 was reported in Heilongjiang. By March 11, 2020, a total of 482 cases domestic case of COVID-19, The incidence rate was 1.28/100 000, the mortality rate was 2.70% (13/482) in 13 municipalities in Heilongjiang. There were 81 clusters of COVID-19, The number of confirmed cases accounted for 79.25% (382/482) of the total confirmed cases and 12 cases of deaths. The family clusters accounted for 86.42% (70/81). Compared with the sporadic cases, the mortality rate, proportion of elderly cases aged 60 or above and severe or critical cases of clinical classification were all higher in the clusters especially the family clusters, but the differences were not significant ( P>0.05). There were 34 clusters involving more than 5 confirmed cases accounted for 41.98% (34/81) of the total clusters, the involved cases accounted for 68.31% (261/382) of the total cases of clusters. There were significant differences in age distribution of the cases among the case clusters with different case numbers. In the clusters involving 6-9 cases, the proportion of cases aged 65 years or above was more (26.53%, 39/147). Conclusions:The incidence rate of COVID-19 was relatively high and the early epidemic was serious in Heilongjiang, The number of cases was large in clusters especially family clusters.
