Objective: To evaluate the immunogenicity and safety of co-administration with bivalent human papillomavirus (HPV) vaccine and hepatitis E virus (HEV) vaccine, so as to provide reference for optimizing the vaccination schedule. Methods: Females aged 18 to 25 years were recruited from September to October 2021 in Hengdian College of Film & Television in Zhejiang Province and randomly divided into the HPV+HEV group, the HPV group, and the HEV group. The vaccination procedures were one dose each at 0, 1, and 6 months. Immunogenicity was evaluated by detecting the geometric mean titers (GMT) of HPV16 IgG, HPV18 IgG, and/or HEV IgG antibodies before the first vaccination and one month after the full course of immunization, and comparing the difference in seroconversion, and the GMT ratio. The non-inferiority margin was set at a seroconversion difference of ≤5%, and the lower limit of the 95%CI of the GMT ratio was >0.5. Safety was evaluated by collecting conjunctive local reactions/events and systemic reactions/events within 7 days after each dose, non-conjunctive adverse events within 30 days after each dose, and serious adverse events throughout the observation period (0 to 7 months). Results: A total of 240 females were included, among whom 236 completed the full vaccination program, including 79 in the HPV+HEV group, 77 in the HPV group, and 80 in the HEV group. One month after the full course of immunization, the seroconversion rates of HPV16 IgG and HPV18 IgG antibodies in both the HPV+HEV group and the HPV group were 100%, and the differences in seroconversion rates were 0 (95%CI: -3.39%-+∞). The seroconversion rates of HEV IgG antibodies in both the HPV+HEV group and the HEV group were 100%, and the difference in seroconversion rates was 0 (95%CI: -3.27%-+∞). The GMT of HPV16 IgG and HPV18 IgG antibodies in the HPV+HEV group was 393.88 and 284.86 IU/mL respectively, which was not inferior to 489.39 and 341.24 IU/mL in the HPV group, and the GMT ratios were 0.80 (95%CI: 0.66-+∞) and 0.83 (95%CI: 0.68-+∞), respectively. The GMT of HEV IgG in the HPV+HEV group was 13.55 U/mL, which was not inferior to 12.72 U/mL in the HEV group, and the GMT ratio was 1.07 (95%CI: 0.92-+∞). The incidences of pain, pruritus, and induration in the HPV+HEV group were 54.43%, 21.52% and 40.51% respectively, which were significantly higher than 10.39%, 0, and 0 in the HPV group (all P<0.05). The incidences of redness/swelling, muscle pain/general weakness in the HPV+HEV group were 2.53% and 0, respectively, which were significantly lower than 12.50% and 16.25% in the HEV group (both P<0.05). Conclusion The co-administration of the bivalent HPV vaccine and HEV vaccine is not inferior to individual vaccination in terms of immunogenicity and safety, and the vaccination plan can be optimized through co-administration.

Objective To investigate immunogenic and toxic effects of graphene oxide (GO) nanoparticles in mouse skeletal muscles and in human blood in vitro. Methods GO nanoparticles prepared using a probe sonicator were supended in deionized H2O or PBS, and particle size and surface charge of the nanoparticles were measured with dynamic light scattering (DLS). Different concentrations (0.5, 1.0 and 2.0 mg/mL) of GO suspension or PBS were injected at multiple sites in the gastrocnemius muscle (GN) of C57BL/6 mice, and inflammatory response and immune cell infiltrations were detected with HE and immunofluorescence staining. We also examined the effects of GO nanoparticles on human red blood cell (RBC) morphology, hemolysis and blood coagulation using scanning electron microscope (SEM), spectrophotometry, and thromboelastography (TEG). Results GO nanoparticles suspended in PBS exhibited better colloidal dispersity, stability and surface charge effects than those in deionized H2O. In mouse GNs, injection of GO suspensions dose- and time-dependently resulted in sustained muscular inflammation and myofiber degeneration at the injection sites, which lasted till 8 weeks after the injection; immunofluorescence staining revealed obvious infiltration of monocytes, macrophages, dendritic cells and CD4+T cells around the injection sites in mouse GNs. In human RBCs, incubation with GO suspensions at 0.2, 2.0 and 20 mg/mL, but not at 0.002 or 0.02 mg/mL, caused significant alterations of cell morphology and hemolysis. TEG analysis showed significant abnormalities of blood coagulation parameters following treatment with high concentrations of GO. Conclusion GO nanoparticles can induce sustained inflammatory and immunological responses in mouse GNs and cause RBC hemolysis and blood coagulation impairment, suggesting its muscular toxicity and hematotoxicity at high concentrations.

Objective : To investigate the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Dongyang City, Zhejiang Province from 2017 to 2022, so as to provide insights into SFTS prevention and control. Methods: Data pertaining to patients with SFTS in Dongyang City from 2017 to 2022 were collected from Notifiable Infectious Disease Reporting System of Chinese Disease Prevention and Control Information System. The epidemiological and clinical characteristics of patients with SFTS were descriptively analyzed, and the trends in incidence of SFTS was evaluated using annual percent change (APC). Results: A total of 32 SFTS cases were reported in Dongyang City from 2017 to 2022, with mean annual incidence of 0.63/105, and 8 cases died, with a fatality rate of 25.00%. The incidence of SFTS appeared a tendency towards a rise from 2017 to 2022 (APC=40.697%, P<0.05). The male to female ratio of SFTS cases was 0.78∶1, and farmer was the predominant occupation (31 cases, 96.88%). SFTS predominantly occurred among individuals at ages of 51 to 69 years (20 cases, 62.50%), and the incidence peaked during the period between March and May and between July and August (28 cases, 87.50%). SFTS cases were reported in 11 out of the 18 townships (streets) in Dongyang City, with the highest number found in Zuocun Township (8 cases, 28.13%), and had the lowest platelet count of (41.46±5.19)×109 platelets/L, with the lowest count of (3.00 to 67.00) ×109 platelets/L. All the SFTS cases had a history of mountain forest and farmland activities 2 weeks prior to onset of the disease, and 5 cases (15.63%) had a history of tick bites. Conclusions The incidence of SFTS appeared a tendency towards a rise in Dongyang City from 2017 to 2022, and SFTS was highly prevalent in spring and summer, with high incidence among farmers. Intensified health education of SFTS is recommended among residents in high-incidence areas.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.

Objective:To explore the trajectory of breast reconstruction in patients with breast cancer at different stages of treatment and to provide reference for medical staff to intervene in breast reconstruction and improve breast reconstruction rate.Methods:During February 2017-October 2017, 192 female patients with breast cancer (aged 20-64 years, mean 49.7 years) were selected by self-designed breast reconstruction demand questionnaire. They were checked up in the diagnosis period, after chemotherapy without chemotherapy, after chemotherapy, and after the completion of chemotherapy.Results:The demand rates for breast reconstruction during the diagnosis period, the period without chemotherapy after mastectomy, the middle period of chemotherapy and after chemotherapy were 10.4%, 13.4%, 16.7% and 17.7% respectively. The main reasons why patients were unwilling to choose breast reconstruction were that patients were worried that breast reconstruction would affect the integrity of cancer resection and worried about cancer recurrence and metastasis. Patients who were unwilling to breast reconstruction planned to choose breast prosthesis, and the difference was statistically significant ( P<0.05). Menopause was the influencing factor of breast reconstruction demand. Conclusions:After chemotherapy, patients have the highest demand rate for breast reconstruction, and more patients are willing to choose the breast reconstruction method of prosthesis implantation. This period is the best period for medical staff to recommend breast reconstruction treatment.

Objective To study the role of nursing risk management in prevention of pressure sores in stroke patients. Methods From January 2016 to December 2016,1,334 stroke patients from the third section,department of neurology of our hospital were assigned as the observation group,where the nursing risk management was applied and meanwhile,another 1,295 stroke patients from the second section of the same department as the control group, where only routine nursing was applied. The two groups were compared in terms of incidence rate and treatment outcome of pressure ulcers.Result The incidence rate of new pressure ulcer and of the observation group was significantly lower than that of the control group (all P＜0.05).Conclusion The nursing risk management in the pressure ulcer prevention for stroke patients significantly reduces the incidence rate of pressure ulcers and improves the cure rate.

Objective To observe the effect of acupuncture at nape points plus nerve electrical stimulation on deglutition function and cerebral blood flow in pseudobulbar palsy after cerebral stroke. Method The eligible subjects were randomized into a control group of 35 cases and a treatment group of 33 cases. The control group was intervened by conventional Western medication, while the treatment group was by acupuncture at nape points plus nerve electrical stimulation in addition to the Western medication, once a day, 4 weeks as a treatment course. Result The total effective rates were respectively 93.9%and 80.0%in the two groups, and the treatment group was significantly superior to the control group; after the intervention, the high whole blood viscosity, low whole blood viscosity, hematocrit, and plasma viscosity all dropped markedly in the treatment group, and were significantly different from that in the control group (P<0.05). The Transcranial Doppler (TCD) showed that the blood flow mean velocity (Vm), systolic velocity (Vs), and pulsatility index (PI) of the left vertebral artery, right vertebral artery, and basilar artery in the treatment group were significantly improved after the intervention (P<0.05), and the Vm and Vs of the left vertebral artery, right vertebral artery, and basilar artery in the control group were significantly improved after the intervention (P<0.05), while PI in the control group didn’t show significant improvement (P>0.05). After the intervention, there were significant differences in comparing the Vm, Vs, and PI of the left vertebral artery, right vertebral artery, and basilar artery between the two groups (P<0.05). Conclusion Acupuncture at nape points plus nerve electrical stimulation is effective in improving the deglutition function in pseudobulbar palsy after cerebral stroke, and its action mechanism is plausibly through improving the cerebral blood flow and promoting the recovery of brain function.

Objective To explore the effects of therapeutic communication skills on violent behaviors in patients with schizophrenia. Methods From January to December 2014 in one level three class A psychiatric hospital, 267 hospitalized male schizophrenic was selected as experimental group undergoing therapeutic communication skills, while another 258 hospital male schizophrenic who had homogenesis as patients in the experimental group at the same time in another ward were chosen as control group receiving routine nursing. The indexes of violent behaviors incidence and protective constraint usage rate were used to assess nursing effects. Results Violent behavior incidence was 32. 58% in the experimental group which was apparently lower than 65. 12% in the control group (χ2 =55. 59, P<0. 01);the usage rate of protective constraint was 73. 56% of the experimental group lower than 85. 71% in the control group (χ2 =5. 63, P<0. 01). Conclusions Therapeutic communication skills effectively reduce the incidence of violent behaviors in patients with schizophrenia and the usage of protective constraints. Therapeutic communication skills also can relieve the complications and tensions between doctors and patients, thus deserve the promotion in psychiatry nursing.

Objective To evaluate the endometrium receptivity of endometriosis (EMs) infertile patients, and observe the influence of TCM treatment to endometrium receptivity and IVF-ET pregnancy outcome. Methods Fifty EMs infertile patients were randomly divided into two groups. The reatment group (30 cases) kept taking TCM for 3 month continuously before IVF-ET embryo transplantation, and the control group (20 cases) received no treatment, with 30 healthy women as normal control. Using transvaginal color doppler ultrasound to detect and compare the endometrial thickness, endometrium and endometrial blood flow distribution types, and uterine artery blood flow parameters in window transvaginal stage. Results There was no difference in endometrial thickness between the EMs infertility patients and the normal group, and the endometrial thickness also had no obvious changes before and after treatment (P>0.05). RI and PI of EMs infertility patients were significantly increased, compared the with normal control group (P<0.05). In treatment group, the persentage of type Ⅰ blood distribution was 23.33%(7/30), in control group was 25.00%(5/20), and 66.67%(20/30) in the normal group, significantly higher than that of the EMs infertility patients (P<0.01). Uterine artery blood flow parameters RI, PI value were significantly decreased after treatment in treatment group, endometrium and endometrial blood flow type Ⅰ distribution increased to 60.00%(18/30). The rate of normal pregnancy was 46.67% (14/30) in treatment group, and control group was 30.00% (6/20). Conclusion EMs may affect uterine artery hemodynamic status and endometrium receptivity. TCM treatment can improve the endometrium receptivity of EMs infertile patients and improve the success rate of IVF-ET.
