Objective To explore the advantages and disadvantages of transvaginal hysterectomy for patients with non-prolapsed uterus,and explore the cause and preventive measurements of the complications of transvaginal hysterectomy.Methods The complications of transvaginal hysterectomy ( group TVH ) in 110 patients with non-prolapsed uterus and of transabdominal hysterectomy ( group TAH ) in 120 patients were compared with each other.These patients were chosen randomly from June 2006 to April 2010.Results In the TVH group,rectum hurt occurred in one patient,prolapse of fallopian tube in one patient and celiac internal bleeding in one patient.The preoperative diagnosis were not consistent with the postoperative diagnosis in four patients.Two patients encountered with postoperative residual end bleeding and four patients with vaginal residual end polyps.In the TAH group,three patients had postoperative diagnosis inconsistent with their preoperative diagnosis.In addition,there were four abdominal wall incision liquefaction ( including two phase suture in two patients),three postoperative bronchial lung infection and two residual end polyps.No celiac internal bleeding and visceral injury occurred in this group.Conclusion TVH has a higher risk of visceral injury and postoperative bleeding than TAH.These complications should be avoided when treating the patients with TVH technique.

OBJECTIVETo observe the effect of Yangfei Ziyin Decoction (YZD) on symptoms, serum levels of TNF-alpha, IL-6, and aquaporin-5 (AQP-5), and pathology of Sj6gren's syndrome (SS) model mice.

METHODSTotally 60 mice were divided into 6 groups according to random digit table, i.e., the model group, the normal control group, the high, medium, low dose YZD groups (administered with YZD at 36.7, 18.4, 9.2 g/kg, 0.2 mL/10 g), the Chinese patent medicine group [CPM, administered with total glucosides of paeony at 0.6 g/kg], 10 mice in each group. All intervention was performed for six successive days in a week, with an interval of one day, a total of 50 days. Body weight, salivary secretion, food and water intake were measured at day10, 20, 30, 40, and 50, respectively. At day 50 blood was collected. Submandibular gland, thymus, and spleen were weighed. Serum levels of TNF-alpha, IL-6, and AQP-5 were detected by ELISA. Pathological changes of submandibular gland were observed. Results Compared with the normal control group, there was no change in water intake of mice in the model group, but with reduced salivary secretion (P < 0.01, P < 0.05). Thymus/spleen/submandibular gland weight and index increased in the model group (P < 0.01, P < 0.05). Compared with the model group at the same time point, salivary secretion increased in the CPM group and 3 YZD groups (P < 0.01 , P < 0.05). Compared with the model group, thymus/spleen/submandibular gland weight and index decreased in the CPM group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index decreased in the low dose YZD group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index, and spleen index decreased in high and medium dose YZD groups (P < 0.01 , P < 0.05). Levels of TNF-alpha and IL-6 decreased, but AQP-5 level increased in the CPM group (P < 0.05). AQP-5 level increased in high and medium dose YZD groups (P < 0.01 , P < 0.05). In the model group alveoli and duct of salivary gland were destroyed, alveoli and duct were irregular, epithelial cells were degenerated, necrotic, and desquamated. Mild-to-moderate lymphocytic infiltration occurred around submandibular gland. Pathological changes were alleviated in the CPM group and 3 YZD groups.

CONCLUSIONYZD could improve clinical symptoms, serum levels of TNF-alpha, IL-6, AQP-5, and pathological changes of SS model mice.

Objective: To establish an optimized path for health management of HBV infections among pregnant and lying-in women based on a Delphi method, so as to provide the evidence for intensifying the interruption of the mother-to-child transmission of HBV. Methods: Based on literature review and previous studies, the preliminary framework and contents of the optimized path for health management of HBV infections were constructed. Experts from epidemiology, clinical medicine and maternal and children healthcare were invited to participate in two-round Delphi consultations, and the preliminarily designed indicators were screened and revised. The score for feasibility of each indicator was calculated, and the weight of each indicator was estimated using a proportional distribution method. Results: Sixteen experts participated in the consultation, including 13 women. The participants had a mean age of (45.69±5.71) years, and a mean employment duration of (23.06±7.05) years. All participants had a degree of bachelor and above, and there were 14 experts with vice senior professional titles. The mean positive coefficient was 96.88% and the mean authority coefficient was 0.790 during the two-round expert consultations. There were significant differences in the coordination coefficient of importance, necessity and feasibility of indicators at all levels (P<0.05), and the coefficient of variation of the feasibility was all less than 0.250. The final optimized path for health management of HBV infections among pregnant and lying-in women included 6 primary indicators, 17 secondary indictors and 73 tertiary indicators. Among the primary indicators, delivery management (0.173 4), screening and evaluation (0.172 8) and pregnancy management (0.172 7) had a high weight. Conclusion A scientific and reliable optimized path is created for health management of HBV infections among pregnant and lying-in women, which has a potential value for improving the interruption of mother-to-child transmission of HBV.

Objective: To investigate the serum levels of anti-measles antibody among residents in Zhejiang Province in 2018, so as to provide insights into measles control. Methods: Permanent residents aged 0 to 59 years were recruited using the stratified multistage random sampling method in Zhejiang Province in 2018, and subjects' demographic features, medical history of measles and history of immunization with measles-containing vaccine (MCV) were collected using a questionnaire survey. The serum level of anti-measles IgG antibody was detected, and the geometric mean concentration (GMC) of anti-measles IgG antibody was estimated. The seroprevalence, protective rate and GMC of anti-measles IgG antibody were compared among residents at different age groups and regions. Results: A total of 4 189 residents were enrolled, including 1 939 males and 2 250 females, with a male to female ratio of 1∶1.16. There were 3 858 residents positive for anti-measles IgG antibody, with seroprevalence of 92.10%, and there were 2 072 residents with protective antibodies against measles, with a protective rate of 49.46%. The median GMC of anti-measles IgG antibody was 798.33 (interquartile range, 1 024.06) mIU/mL, and the protective rate of anti-measles IgG antibody appeared a tendency towards a decline with age ( χ2trend=18.067, P<0.001 ). There were significant differences in the seroprevalence ( χ2=45.090, P<0.001 ), protective rate ( χ2=57.432, P<0.001 ) and GMC of anti-measles IgG antibody (χ2=88.624, P<0.001 ) among residents at different regions, with the lowest seroprevalence of anti-measles IgG antibody in Ningbo City ( 85.19% ), the lowest antibody-protective rate (38.98%) and the lowest GMC [632.89 ( 909.04 ) mIU/mL] in Zhoushan City, the highest seroprevalence ( 95.16% ), antibody-protective rate (58.48%) and GMC [1 035.84 ( 1 301.77 ) mIU/mL] in Huzhou City. Conclusions The protective rate of anti-measles antibody was low and appeared a tendency towards a decline among residents in Zhejiang Province in 2018. There was a region-specific serum level of anti-measles antibody in Zhejiang Province in 2018.

Abstract Vaccine-hypervariable poliovirus type Ⅲ was detected in an acute flaccid paralysis infant at age of 6 months in Zhejiang Province in June, 2021, and the isolated and incubated virus had six nucleotide variations in the VP1 region as compared to the poliovirus Sabin vaccine strain. The infant had a history of three-dose poliovirus vaccination, and grade 2 muscle strength of the left upper limb upon onset. He was clinically diagnosed with cellulitis of the left shoulder, and recovered to normal following treatment. No abnormality was detected in the nervous system, and the infant was cured and discharged from hospital. No vaccine-hypervariable poliovirus was detected in subsequent infant' clinical samples or in close contacts, and no similar cases were identified during the active case detection by county/district medical institutions and among community populations. Since the infant did not present poliomyelitis-related clinical symptoms caused by vaccine-hypervariable poliovirus, poliomyelitis was excluded. The vaccine-hypervariable poliovirus was not spread because of timely identification and effective responses, suggesting the urgent need to maintain the sensitivity of the acute flaccid paralysis surveillance system and improve the coverage of poliovirus vaccination, so as to inhibit the transmission of poliovirus.

Objective:To validate the predictive function of Field Assessment Stroke Triage for Emergency Destination (FAST-ED) score on large vessel occlusion (LVO) in Chinese population.Methods:The information about the patients who had the disease onset within 24 hours, were treated in the Emergency Department of Jinling Hospital, and diagnosed as ‘acute ischemic stroke’ was collected. Via the emergent brain computed tomography angiography or digital subtraction angiography, the patients were divided into LVO group and non-LVO group. The scores of FAST-ED were calculated according to the National Institutes of Health Stroke Scale (NIHSS) scores and compared with Rapid Arterial oCclusion Evaluation (RACE), 3-item Stroke Scale (3I-SS), Cincinnati Stroke Triage Assessment Tool (C-STAT), and Prehospital Acute Stroke Scale (PASS) scores. Moreover, the patients were further divided into anterior and posterior circulation lesion groups to explore whether the FAST-ED scale can differ the anterior or posterior circulation effectively.Results:Three hundred and eighty-one patients were eventually included, among whom 284 were diagnosed as LVO, and 97 were diagnosed as non-LVO. Receiver operating characteristic curves showed that cut-off value of 4 optimized the scale (sensitivity: 0.76, specificity: 0.69, area under the curve: 0.78). The area under the curve of FAST-ED score(0.78) showed no statistically significant difference with NIHSS (0.79), RACE (0.77), 3I-SS (0.78) and C-STAT scores (0.75), and exhibited statistically significant difference with PASS score (0.74; 95% CI 0.69-0.78, P=0.01). FAST-ED score showed no statistically significant difference in predicting anterior and posterior circulation lesions. Conclusions:FAST-ED score can predict LVO in a rather accurate manner. It can predict anterior and posterior circulation lesions with similar effectiveness. So FAST-ED is able to be a prehospital screening tool and make assistance to the prehospital treatment.

Objective: To analyze the strengths, weaknesses, opportunities and threats of the construction on intelligent vaccination clinics in Zhejiang Province, so as to provide countermeasures for promoting the construction of intelligent vaccination clinics in Zhejiang Province. Methods: By reviewing the annual reports of Zhejiang immunization planning, survey data from Zhejiang Centers for Disease Control and Prevention and Immunization Intelligent Service System, data of human resources of immunization planning, vaccine procurement, construction progress of intelligent vaccination clinics and vaccination were collected. The relevant literature was searched to gather information on the construction standards and norms of intelligent vaccination clinics. The analysis of the strengths, weaknesses, opportunities and threats (SWOT) of the construction of intelligent vaccination clinics was conducted, and corresponding countermeasures and suggestions were proposed. Results: The National Immunization Program reported vaccine rate in Zhejiang Province is more than 99%, and standardized vaccination clinics have been popularized throughout the province. The vaccination staff are professional, and a province-wide intelligent immunization service information system has been established, providing the resources and conditions for the construction of intelligent vaccination clinics. However, there are problems such as low data quality and matching efficiency in vaccination, insufficient data interoperability and sharing, unbalanced regional capabilities in intelligent transformation, and uneven distribution of talent and resources. It is crucial to seize the opportunities presented by the development of big data and artificial intelligence, rely on the regional development of the Internet and health industry, seize the opportunity of rapid growth in demand for intelligent vaccination services and high public acceptance, accelerate the construction of intelligent vaccination clinics, and establish intelligent vaccination service standards as soon as possible. Conclusion We should seize the opportunities presented by the digital reform and development, fully utilize the existing vaccination resources and strengths, address the shortcomings, and accelerate the construction of intelligent vaccination clinics in Zhejiang Province.

PURPOSE: Insulin resistance plays a role in the development of dementia and hypertension. We investigated a possible relationship between cognitive impairment and insulin resistance in elderly Chinese patients with primary hypertension. MATERIALS AND METHODS: One hundred and thirty-two hypertensive elderly patients (>60 years) were enrolled in this study, and assigned into either the cognitive impairment group (n=61) or the normal cognitive group (n=71). Gender, age, education, body mass index (BMI), waist hip ratio (WHR), total cholesterol (TC), triglyceride (TG), C-reactive protein (CRP), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), creatinine (Cr), fasting plasma glucose (FPG), fasting insulin (FINS), homeostasis model of assessment for insulin resistance index (HOMA-IR), systolic blood pressure, diastolic blood pressure, smoking history, atherosclerosis and the proportion of uncontrolled hypertension were compared between the two groups. Multi-factorial logistic regression analysis was performed. RESULTS: No significant differences were found in gender, age, TC, CRP, HDL-C, LDL-C, Cr, BP, smoking history, atherosclerosis and the proportion of uncontrolled hypertension between the two groups. The cognitive impairment group had lower education levels, and higher BMI, WHR, TG, FPG, FINS, and HOMA-IR levels than the control group. Logistic regression analysis revealed the levels of education, BMI, WHR, and HOMA-IR as independent factors that predict cognitive impairment in patients. CONCLUSION: Our study demonstrates that poor education and increased BMI, WHR, and HOMA-IR are independent risk factors for cognitive impairment in elderly patients with hypertension. Insulin resistance plays an important role in the development of cognitive impairment in primary elderly hypertensive patients.

OBJECTIVETo explore the role of autophagy in doxorubicin (DOX)-induced resistance of human myeloma cell line RPMI8226.

METHODSWe established doxorubicin induced resistant subline of myeloma cell line RPMI8226/DOX by drug concentration step-elevation method. Resistant index of DOX was measured by MTT assay. Autophagy of myeloma cell lines RPMI8226/s and RPMI8226/DOX was detected by transmission electron microscopy, immunofluorescence (LC3-FITC) and western blot respectively. Apoptosis of RPMI8226/DOX cells induced by DOX combined with autophagic inhibitor hydroxychloroquine or 3-MA was identified by AnnexinV-FITC/PI double fluorescence dyeing.

RESULTSResistant index of RPMI8226/DOX was approximately 10.8 fold of that of RPMI8226/S. Electron microscopic studies revealed that most of RPMI8226/DOX cells displayed viable attributes and contained numerous autophagic vacuoles. Fluorescent images of RPMI8226/DOX cells showed a punctuate distribution in LC3 protein. Increased LC3-II protein in RPMI8226/DOX cells was determined by immunoblotting. There were no differences among 8 μmol/L HCQ (3.24±1.08)%, 10 mmol/L 3-MA (2.81±0.80)% or control \[(2.12±1.24)%\] (P>0.05) in terms of AnnexinV-FITC/PI double fluorescence dyeing; Compared with apoptosis of (9.75±2.15)%, (24.36±2.16)% and (40.51±3.14)% of RPMI8226/DOX cells under 2, 4 and 6 μmol/L DOX, apoptosis increased significantly after 24 h incubation under 2, 4 and 6 μmol/L DOX combined with 8 μmol/L HCQ as of \[(16.56±1.89)%, (36.44±2.91)% and (62.68±3.75)%, respectively\], or under 2, 4 and 6 μmol/L DOX combined with 10 mmol/L 3-MA as of \[(15.47±1.85)%, (39.28±3.06)% and (55.46±4.07)%, respectively\] (P<0.05).

CONCLUSIONAutophagy was involved in doxorubicin-induced resistance of myeloma cell line RPMI8226, DOX resistance in myeloma cells was reversed partly by autophagy inhibitor hydroxychloroquine or 3-MA, and autophagy may be one of mechanisms for drug resistance.
