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 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.

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 study the short-term clinical efficacy and its possible mechanism of refractory hypertension(RH) treated by continuous veno-venous hemofiltration (CVVH) in maintenance hemodialysis (MHD) patients. Methods Thirty-four MHD patients with RH treated with CVVH enrolled in the treatment group,all these patients were treatment of 2 -3 times,each time 8 - 10 hours. Thirty MHD patients with wellcontroled blood pressure were recruited as control. Changes of blood pressure, dry weight, plasma levels of parathyroid hormone (PTH), renin ( RA), angiotensin Ⅰ , Ⅱ ( AT Ⅰ , AT Ⅱ ), aldosterone ( Ald ) were observed before and after hemodialysis. Results In the treatment group,compared with pre-treatment, the blood pressure decreased significantly with an effective rate of 64.7% and efficient rate of 100. 0%. Before treatment, plasma RA was ([1.10 ±0.25] μg/(L · h)and [0:78 ±0.26] μg/(L · h),AT Ⅰ was [0.89 ±0.21] μg/L and [ 0. 52 ± 0. 14 ] μg/L, AT Ⅱ was [ 177.68 ± 89.46 ] ng/L and [ 89. 25 ± 12. 84 ] ng/L, Ald was [72. 06 ± 11.47 ]ng/L and [ 48.92 ± 8. 65 ] ng/L, PTH was [ 306. 81 ± 69. 37 ] ng/L and [ 248.76 ± 134. 62 ] ng/L in the treatment and control group respectively. All the measurements in the treatment group were significantly higher than those in the control group (P ＜ 0. 05 ). In the treatment group, compared to pre-treatment, plasma RA significantly decreased ( [ 1.10 ± 0. 25 ]μg/ ( L · h) vs [ 0. 76 ± 0. 17 ] μg/( L · h ), as well as AT Ⅰ ( [ 0. 89 ±0.21]μg/L vs [0.50 ±0.12] μg/L),ATⅡ([177.68±89.46]ng/L vs [ 87.13±14.22] ng/L),Ald ([72.06±11.47]ng/Lvs [ 46. 01± 9. 86 ] ng/L ) and PTH ( [ 306. 81 ±69.37]ng/L vs [ 186.53 ±32.93 ] ng/L) ( P ＜ 0. 05 ). However, there was no significant changes in the above mentioned measurements between before and after hemodialysis in the control group (P ＞ 0. 05). Conclusion CVVH may be an effective methods in the treatment of MHD patients with RH, and its antihypertensive mechanisms may be that CVVH can effectively remove the excess water in the body, and reduce plasma RA, AT Ⅰ , AT Ⅱ ,Ald and PTH levels.

Objective To detect the expression of Toll-like receptor 9 (TLR9) in pancreatic cancer,and to explore its clinical significance. Methods The real-time PCR, Western blotting and immunohistochemistry were used to examine the expression of TLR9 in 30 samples of pancreatic cancer and the adjacent tissues, and 10 samples of normal pancreatic tissues. The relationships of TLR9 with clinicopathological parameters were analyzed. Results Compared with normal pancreatic tissues, the amplification value of TLR9 mRNA expression was 2.32 fold (1.41 ～ 3.22 ) in human pancreatic cancer, was 1.23 fold (1.18 ～ 1.28) in paracancerous tissues, respectively, and the difference was statistically significant (P ＜ 0.05 ). The percentage of positive cells expressing TLR9 protein in human pancreatic cancer tissues,paracancerous tissues and normal tissues were 73.3% (22/30), 33.3% (10/30) and 20.0% (2/10), and the relative expressions of TLR9 protein were 0.780 ±0. 026,0. 400 ±0.018,0. 173 ±0.043 ,respectively, and the difference was statistically significant( P ＜ 0.05 ). The highly expressed TLR9 was positively correlated with the degree of tumor differentiation, TNM stage and lymph node metastasis. Conclusions TLR9 was highly expressed in pancreatic cancer tissues. TLR9 expression plays a role in the canceration of pancreatic tissues.
