Objective: To evaluate the implementation of vaccination certificate verification in Guizhou Province from 2020 to 2022, so as to provide reference for improving the efficiency of vaccination certificate verification and vaccine re inoculation work. Methods: Data was drawn from the 2020-2022 report on the verification of vaccination certificates for children entering daycare and enrollment in various cities and prefectures in Guizhou Province. In July, 2021, Guizhou Province began to implement a new inspection scheme with close cooperation between health and education departments, moving forward the gateway, parents using "Guizhou CDC" WeChat official account for self inspection, and a long term supervision and assessment mechanism. A comparative analysis was conducted on the evaluation of vaccination certificate verification rate, vaccination certificate holding rate, full revaccination rate of the National Immunization Program (NIP) for children and full vaccination rate of the NIP vaccine before(2020) and after(2021 and 2022) the implementation of the new plan. Chi square test was used for statistical analysis. Results: The rate of vaccination certificate verification of children enrolled in kindergarten and primary school in Guizhou Province increased from 99.85% in 2020 to 100% in 2022, the rate of holding certificate increased from 99.55% in 2020 to 99.91% in 2022, the rate of full vaccination NIP vaccines for kindergarten and primary school entry increased from 78.95% in 2020 to 96.59% in 2022, and the rate of full revaccination increased from 42.40% in 2020 to 79.19% in 2022 ( χ 2=2 203.19, 3 651.67, 291 896.31, 103 938.76, P < 0.01 ). Conclusions From 2020 to 2022, the rates of full vaccination and the full revaccination for NIP vaccine among children entering kindergarten in Guizhou Province have increased year by year. Each region should fully utilize the achievements of immunization planning informatization construction to establish effective inspection work ideas, and ensure that eligible children complete the full vaccination process of the national immunization plan vaccine.

Objective:This study explored the consistency of liquid chromatography-tandem mass spectrometry (LC-MS/MS) and immunoassay for the detection of steroid hormones. The diagnostic value of multiple steroid hormones in 21-hydroxylase deficiency (21-OHD) was investigated and the follow-up indicators were screened.Methods:This experimental group included 109 patients with typical 21-OHD who received standard treatment, and the control group included 94 normal children. 17-hydroxyprogesterone (17-OHP), androstenedione (Δ4-A), testosterone and cortisol were detected by immunoassay and LC-MS/MS method. At the same time, 16 other adrenal steroids were detected by LC-MS/MS method. The experimental group was divided into: (1) overtreatment group: 17OHP<4 ng/ml; (2) well controlled group: 4 ng/ml≤17-OHP<12 ng/ml; (3) poorly controlled group: 17-OHP≥12 ng/ml. The following studies were carried out. (1) The consistency of immunoassay and LC-MS/MS detection results was analyzed; (2) The serum concentrations of various steroid hormones in patients with 21-OHD and the control group were compared to explore the diagnostic value of multiple steroid hormones detection; (3) The concentration differences of 20 kinds of steroid hormones in 21-OHD patients with different therapeutic effects were compared to screen more valuable follow-up indicators.Results:(1) among the four indicators detected by LC-MS/MS and immunoassay, the consistency of T and 17-OHP was high. The concentrations of cortisol and Δ4-A determined by immunoassay were higher than those determined by LC-MS/MS. (2) Among the 20 kinds of steroid hormones secreted by adrenal gland detected by LC-MS/MS, 6 kinds of hormones were significantly higher and 6 kinds of hormones were significantly lower in 21-OHD patients compared with the control group, ,and 8 kinds of steroids showed no statistical difference. (3) 17-OHP decreased and 11-deoxycortisol increased in over-inhibition group, while 17-OHP, pregnenolone, progesterone, 17-hydroxypregnenolone, 21-deoxycortisol, Δ4-A and estrone increased in the poorly controlled group.Conclusions:LC-MS/MS can detect many kinds of steroid hormones at one time with better evaluate dimensions. During the follow-up, only 8 of the 20 hormones were closely related to the control status of patients, suggesting that unnecessary testing work could be reduced.

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%－6.1%) and 13.1% (95% CI: 11.3%－14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Objective To analyze the clinicopathological features and prognosis of immunoglobulin G (IgG)4-related diseases with interstitial nephritis. Methods Forty cases of IgG4-related diseases diagnosed by pathology in our hospital from 2014 to 2018 were collected and their clinicopathological features were analyzed. Four patients with IgG4-related disease with interstitial nephritis were analyzed, including clinical laboratory tests and histopathological features, and immunohistochemical analysis of the type and proportion of renal interstitial infiltrating cells. At the same time, the treatment and prognosis of the patients were analyzed. Results Among 40 cases of IgG4-related diseases, 11 cases had parotid submandibular gland involvement (accounted for 28％), labial gland involvement (7 cases, 18％) and lymph node enlargement (6 cases, 15％). Patients with kidney involvement (4 cases, 10％) all presented with IgG4-related tubulo-interstitial nephritis (IgG4-TIN). All of them were elderly males, and 2 had glomerulopathy. One of them had anti-neutrophil cytoplasmic antibodies (ANCA)-related vasculitis renal damage. The number of CD4-positive cells in renal interstitium was more than CD8-positive cells. Another case complicated with IgA nephropathy. Renal dysfunction occurred in all 4 cases, and serum IgG4 level ranged from 4.65 g/L to 23.8 g/L. All 4 patients received glucocorticosteroid and symptomatic treatment, and the prognosis was good. Conclusion IgG4-related diseases may involve mul-tiple organs, renal dysfunction may occur when the kidney is involved. Interstitial nephritis is the major clinical manifestation. Glomerular lesions may accelerate the progress of IgG4-TIN. Corticosteroid therapy is effective.

OBJECTIVE: To explore whether β1 receptor blocker could decrease the myocardial inflammation through the Toll-like receptor 4/nuclear factor-ΚB (TLR4/NF-ΚB) signaling pathway in the sepsis adult rats. METHODS: Sixty male Wistar rats (250-300 g) aged 3 months old were allocated to four groups by random number table (n = 15): sham operation group (S group), sepsis model group (CLP group), β1 receptor blocker esmolol intervention group (ES group), and inhibitor of the TLR4 E5564 intervention group (E5564 group). The rat sepsis model was established by cecal ligation and puncture (CLP); S group of rats underwent only an incision. Rats in S group, CLP group and E5564 group were subcutaneous injected with 0.9% sodium chloride (NaCl) 2.0 mL/kg. Besides, the rats in ES group were injected with esmolol (15 mg×kg^-1×h^-1) by micro pump through the caudal vein. The rats in E5564 group were injected with E5564 (0.3 mg×kg^-1×h^-1) by micro pump through the caudal vein 1 hour before the CLP surgery. Samples were collected 6 hours after the modelling in each group. The average arterial pressure (MAP) and cardiac output index (CI) were monitored by PU electrical conduction ECG monitor. The levels of serum cardiac troponin I (cTnI), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA). The expressions of TLR4, NF-ΚB p65, IL-1β, TNF-α in myocardial tissue was detected by Western Blot. RESULTS: There was no significant difference in MAP in each group. Compared with the S group, the CI in the CLP group was significantly decreased, the levels of serum cTnI, IL-1β, TNF-α were significantly increased, the protein expressions of myocardial tissue TLR4, NF-ΚB p65, IL-1β and TNF-α were significantly increased. Compared with the CLP group, the CI in the ES group and E5564 group were significantly increased (mL×s^-1×m^-2: 58.6±4.3, 58.9±4.4 vs. 41.2±3.9, both P < 0.01), the levels of serum cTnI, IL-1β and TNF-α were significantly decreased [cTnI (μg/L): 1 113.81±26.64, 1 115.74±25.90 vs. 1 975.96±42.74; IL-1β (ng/L): 39.6±4.3, 38.9±4.4 vs. 61.2±3.9; TNF-α (ng/L): 43.1±2.8, 48.7±2.6 vs. 81.3±4.4, all P < 0.01], the protein expressions of myocardial tissue NF-ΚB p65, IL-1β, TNF-α were significantly decreased (NF-ΚB p65/β-actin: 0.31±0.03, 0.43±0.04 vs. 0.85±0.08; IL-1β/β-actin: 0.28±0.05, 0.32±0.03 vs. 0.71±0.06; TNF-α/β-actin: 0.18±0.04, 0.28±0.03 vs. 0.78±0.07, all P < 0.01), but there was no significant difference in protein expression of TLR4 (TLR4/β-actin: 0.89±0.07, 0.87±0.09 vs. 0.95±0.09, both P > 0.05). There was no significant difference in CI, the levels of serum cTnI, IL-1β, TNF-α, and the protein expressions of myocardial tissue TLR4, NF-ΚB p65, IL-1β, TNF-α between ES group and E5564 group (all P > 0.05). CONCLUSIONS β1 receptor blocker esmolol may inhibit myocardial inflammatory response in sepsis adult rats through TLR4/NF-ΚB signaling pathway, thereby alleviating sepsis-induced myocardial injury.
