We have investigated the situation about recent interdisciplinary construction for medical subject from several 985-project universities in China as well as the well-known overseas universities via internet. We also have analyzed the results and in mean time, put forward some related suggestions in order to probe an available strategy of interdisciplinary construction for medical subject in the universities of China.

In order to affirm the cardioactive components in Fuzi, we identified a group of aminoalcohol- diterpenoid alkaloids in Fuzi using ultra high-performance liquid chromatography coupled with electrospray ionization mass spectrometer (UPLC-ESI-MS) method. Among a total of forty-one isolated ingredients, thirteen major aminoalcohol-diterpenoid alkaloids were identified by comparing their retention times and MS spectra with those of the reference substances. Moreover, Fuzi samples from different places of origin and with different processing methods were examined and their components displayed a pattern of high similarity, though the relative abundance varies probably due to their different processing methods. Furthermore, the cardiac effect of each identified alkaloid was individually evaluated using the isolated bullfrog heart perfusion experiment. Among the thirteen aminoalcohol diterpenoid alkaloids tested, six of them significantly enhanced the amplitude rates. Taken together, we affirm that the cardioactive components in Fuzi are aminoalcohol-diterpenoid alkaloids, shedding light on future studies of the mechanisms and development of these cardioactive compounds.

Objective: To examine the association between sleep and frailty using the bidirectional two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and intervention of frailty. Methods: The data on single nucleotide polymorphisms (SNP) related to sleep duration, insomnia and morning chronotype were collected from genome-wide association studies (GWAS) and meta-analysis of GWAS, involving 446 118, 1 331 010 and 697 828 participants, respectively. The frailty was evaluated using the frailty index, and the relevant SNP data were collected from a meta-analysis of GWAS involving 175 226 participants. A bidirectional MR analysis was performed using the inverse-variance weighted method. Sensitivity analyses employed the weighted median method, the maximum likelihood-based method, the MR-Egger regression, and the MR-PRESSO test. Results: Forward MR analysis showed that longer sleep duration (β=-0.170, 95%CI: -0.255 to -0.085) and morning chronotype (β=-0.036, 95%CI: -0.058 to -0.014) decreased the risk of frailty, while insomnia increased the risk of frailty (β=0.167, 95%CI: 0.149-0.184). Reverse MR analysis showed that frailty increased the risk of insomnia (OR=1.645, 95%CI: 1.278-2.117). Both bidirectional MR results were robust, which excluded the impact of heterogeneity and horizontal pleiotropy. Conclusion Sleep duration, insomnia, and morning chronotype are associated with frailty.

Objective:To explore the effects of nutrition management based on Patient-Generated Subjective Global Assessment (PG-SGA) on nutritional idicators,quality of life and other indicators in patients with pancreatic cancer undergoing chemotherapy, to provide guidance for the implementation of the intervention plan for pancreatic cancer patients undergoing chemotherapy.Methods:This was a randomized controlled study. From January 2021 to December 2022, 96 patients with pancreatic cancer who received chemotherapy in Shanghai Changzheng Hospital and Affiliated Cancer Hospital of Fudan University were selected using convenience sampling method and divided into the observation group and the control group according to the random number table, with 48 cases in each group. The control group was given routine nursing intervention, and the observation group was given PG-SGA-based nutrition management intervention. Patients in both groups continued the intervention until discharge. Nutritional indexes, quality of life, the score of cancer-related fatigue, sleep quality and mental state before and after intervention, intervention compliance and satisfaction after intervention, and complications during intervention of both groups were compared.Results:There were 48 patients in each group ultimately. In the control group, there were 28 males, 20 females, aged (63.33 ± 4.31) years old; in the observation group, there were 27 males, 21 females, aged (63.15 ± 4.25) years old. After intervention, the PG-SGA score, serum triacylglycerol level, and scores of Revised Piper ′s Fatigue Scale and Arsens Insomnia Scale, Self-rating Anxiety Scale and Self-rating Depression Scale in the observation group were (3.87 ± 1.16) points, (1.35 ± 0.52) mmol/L, (3.79 ± 0.67) points, and (5.31 ± 2.05), (44.55 ± 5.14), (45.15 ± 5.08) points respectively, lower than the control group ′s (5.77 ± 1.58) points, (2.04 ± 0.35) mmol/L, (4.82 ± 0.88) points, and (7.29 ± 2.14), (51.74 ± 5.18), (52.26 ± 5.11) points, the differences were statistically significant ( t values were 4.63-7.63, all P<0.05); the serum levels of retinol binding protein and transferrin were (18.13 ± 2.41) mg/L and (61.25 ± 5.34) ng/L, respectively, higher than the control group ′s (15.29 ± 2.33) mg/L and (48.31 ± 5.28) ng/L, with statistical significance ( t=5.87, 11.94, both P<0.05). The symptom domain score in the observation group after intervention was (56.17 ± 5.25) points, lower than (66.22 ± 5.57) points in the control group, while the cognitive, social, emotional, role, and physical scores were (76.35 ± 5.71 ), (77.55 ± 6.51 ), (75.87 ± 6.45), (77.38 ± 6.61), (75.75 ± 6.37) points, higher than (66.29 ± 5.39), (65.74 ± 6.34 ), (64.22 ± 6.18), (66.56 ± 6.26), (65.74 ± 6.11) points in the control group ( t values were 7.86 to 9.10, all P<0.05). Conclusions:Nutritional management based on PG-SGA could reduce the degree of cancer-induced fatigue, relieve negative emotions, improve the overall nutritional status, improve intervention compliance, reduce the occurrence of complications; improve sleep quality, quality of life, and patient ′s satisfaction.

Objective:To analyze influencing factors of instant antiretroviral therapy (ART) and explore associution between strategies of ART and immunological effects among HIV/AIDS patients in Taizhou city during 2006-2019.Methods:A retrospective cohort study was conducted on HIV/AIDS patients under ART, and a logistic regression model was used to analyze factors of instant ART. The student t-test and chi-square test were used to compare immunological effect of different ART strategies while the Kaplan-Meier method was used to generate a survival curve. Results:A total of 2 971 HIV/AIDS patients were enrolled with 1 786 cases (60.1%) having instant ART strategy. The proportion of instant ART were 77.8% (1 170/1 504) during 2016 to 2019. The treatment success rate of the instant ART group (87.4%, 1 561/1 786) were higher than the delayed ART group (84.4%, 1 000/1 185). The results of multivariate logistic regression model indicated that male (a OR=1.28, 95 %CI: 1.03-1.59), married (a OR=1.71, 95 %CI: 1.33-2.19) and baseline CD 4+T lymphocyte cells (CD 4) counts ≤200 cells/μl (a OR=1.60, 95 %CI: 1.27-2.02) were factors positively related to instant ART while 31-40 years old (a OR=0.63, 95 %CI: 0.48-0.84), infected through heterosexual transmission(a OR=0.60, 95 %CI: 0.49-0.74) and diagnosed before 2015 (a OR=0.20, 95 %CI: 0.17-0.23) were inversely related to instant ART. The increase of the CD 4/CD 8 ratio was greater, and the cumulative ART success rate was higher each year in the instant ART group than in the delayed ART group ( P<0.05). Conclusions:The instant ART strategy has been well implemented in Taizhou city during 2006-2019, and the immunological effect was better in instant ART group. The proportion of instant ART were more than 60.0% among HIV/AIDS patients. Instant ART strategy needs to be strengthened for those who are 31-40 years old, women, unmarried, and infected through heterosexual transmission in an attempt to further increase treatment level and improve treatment effect.

Objective:To explore the dynamic change of platelet count and related factors in HIV-infected patients with access to antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefecture of Yunnan province.Methods:A longitudinal analysis was used to analyze the dynamic change of platelet count in HIV-infected patients with access to ART. Linear mixed model (LMM) was used to analyze factors associated with the dynamic change of platelet count. Stratified analysis and sensitivity analysis were also conducted.Results:A total of 761 HIV-infected patients were recruited and 608 cases had at least one follow-up record (80.0%,608/761). 374, 555 and 233 cases were investigated in follow-up visits at month 6, 12 and 24, respectively. The mean platelet count and the proportion of higher platelet count (>300×10 9/L) were significantly higher in women than in men at both baseline survey and each follow-up visit ( P<0.05). Among patients with no obvious liver fibrosis, the mean platelet count was significantly higher in women than in men at baseline survey and each follow-up visit; while in the patients with liver fibrosis, the mean baseline platelet count was still significantly higher in women than in men, but the difference had no significance at follow-up visits. Results of LMM revealed that follow-up platelet count was positively correlated with gender ( β=5.90, 95% CI: 1.09-10.70, P=0.016), baseline platelet count ( β=0.82, 95% CI: 0.79-0.86, P<0.001) and time ( β=1.76, 95% CI: 1.52-2.01, P<0.001). Sensitivity analysis among 220 cases who had both 12- and 24-month follow-up visits further confirmed that follow-up platelets count was still positively associated with gender ( β=10.50, 95% CI: 2.24-18.74, P=0.013), baseline platelet count ( β=0.71, 95% CI: 0.65-0.77, P<0.001) and time ( β=1.60, 95% CI: 1.20-1.99, P<0.001) but negatively associated with age ( β=-0.42, 95% CI: -0.78--0.06, P=0.021). Conclusions:The platelet count of HIV-infected patients gradually increased after ART. The mean platelet count was consistently higher in women than in men. Attention should be paid to the gender specific difference in platelet count in HIV-infected patients and timely intervention should be given to reduce the morbidity and mortality of platelet-related diseases.

OBJECTIVE：To compare the protective effects model mice between the aboveground and underground parts of Astragalus membranaceus on immunosuppression ，and to provide reference for further utilization and development of A. membranaceus. METHODS ：A total of 240 ICR mice were divided into 4 batches，60 mice in each batch ，with half male and half female. Each batch of mice were randomly divided into blank group ，model group ，A. membranaceus aboveground part and undergroud part low-dose and high-dose groups （3，6 g/kg，by crude drug ）according to body weight and sex ，with 10 mice in each group. Blank group and model group were given normal saline intragastrically. A. Membranaceus groups were given corresponding concentration of drug intragastrically ，10 mL/kg，once a day ，for consecutive 30 days. Except for blank group ， other groups were intraperitoneally injected with cyclophosphamide 40 mg/（kg·d）for consecutive 3 days，since 24th day of treatment，to establish immunosuppression model. The levels of serum immunoglobulin （IgG，IgM，IgA），inflammation factors [nitric oxide ，interleukin-2（IL-2），IL-6，tumor necrosis factor-α] and half hemolysis value were detected in each group. Body weight ，thymus index ，spleen index ，phagocytic index ，activity of natural killer （NK）cell，splenic lymphocyte proliferation ability，dinitrofluorobenzene-induced delayed metamorphosis reaction in mice （by weight difference between left and right ears ） and the number of hemolytic plaque were determined. RESULTS ： Compared with blank group ， the serum levels of immunoglobulin，body weight ，thymus index ，spleen index ，phagocytic index ，NK cell activity ，the proliferation ability of splenic lymphocyte，the number of hemdytic plaque and half hemolysis value were decreased significantly in model group （P＜0.05）， while inflammation factor level as well as weight difference between left and right ears were increased significantly （P＜0.05）. Compared with model group ，above indexes of mice in A. membranaceus groups were improved significantly ，in dose-dependent manner（P＜0.05）. Compared with A. membranaceus undergroud part group ，above indexes of A. membranaceus aboveground part group were improved significantly （P＜0.05）. CONCLUSIONS ：Aboveground and underground part of A. membranaceus both have pretective effect on immunosuppression model mice ，and the effect of aboveground part of A. membranaceus is stronger than underground part of A. membranaceus .

Objective:To evaluate the efficacy of long-pulsed 1 064-nm Nd:YAG laser combined with a topical emulsion containing Camellia reticulata and Radix Notoginseng in the treatment of melasma. Methods:A total of 80 patients with melasma were enrolled from Department of Dermatology, People′s Hospital of Ningxia Hui Autonomous Region from June 2019 to June 2020, and randomly and equally divided into control group and observation group by using a random number table: 40 patients in the control group were treated with long-pulsed 1 064-nm Nd:YAG laser once every 2 weeks for 6 sessions as a course of treatment; another 40 in the observation group were treated with the same laser therapy as the control group and a topical emulsion containing Camellia reticulata and Radix Notoginseng twice a day for 3 months as a course of treatment. Melasma area and severity index (MASI), clinical efficacy, patient satisfaction rate and safety were compared between the 2 groups before and/or after treatment. Results:After 4- and 8-week treatment, there was no significant difference in the MASI score between the observation group (14.57 ± 3.22 points, 10.00 ± 2.94 points, respectively) and control group (14.74 ± 3.11 points, 11.31 ± 3.00 points, respectively; both P>0.05). After 12-week treatment, the MASI score was significantly lower in the observation group (4.80 ± 2.78 points) than in the control group (7.07 ± 3.22 points, t = -3.38, P<0.01). After 3-month treatment, the response rate was significantly higher in the observation group (36 cases, 90%) than in the control group (31 cases, 77.5%; χ2 = 4.58, P < 0.001) ; however, there was no significant difference in the patient satisfaction rate between the observation group (87.5%) and control group (72.5%, χ2 = 7.26, P = 0.06). In addition, no significant difference in the occurrence of adverse reactions was observed between the observation group (5 cases, 12.5%) and control group (7 cases, 17.5%; P > 0.05) . Conclusion:Compared with the long-pulsed 1 064-nm Nd:YAG laser alone, the topical emulsion containing Camellia reticulata and Radix Notoginseng in combination with the long-pulsed 1 064-nm Nd:YAG laser is more effective for the treatment of melasma, with higher patient satisfaction and less adverse reactions.
