Objective To explore the current situations in self-management of cancer patients over peripherally inserted central catheter (PICC) and the influencing factors. Method Self-designed general demographic data form, disease-related questionnaire and PICC self-management ability for cancer patients were used to investigate 98 tumor patients with PICC. Results The total score on self-management ability of the cancer patient with PICC was (150.85 ± 17.35). The influencing factors of their self-management of PICC included education level, economic condition, presence or absence of long-term caregivers and cognitive disorders, all contributive to the prediction of 28.60%total variance for the patients′self-management capability. Conclusions Cancer patients have a better ability in managing PICC, but a few patients failed to grasp self-management skills, which was resulted from many factors. Nurses should pay more attention to those with less education, under poorer economic conditions and without long-term caregivers, and provide them with more care and education so as to comprehensively improve their self-management skills.

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.

BACKGROUND:The incidence of low serum level of vitamin D in patients undergoing hip arthroplasty and its impact has not been reported in China, indicating that it has not been brought to the forefront. OBJECTIVE:To determine the prevalence of low serum level of vitamin D in patients before total hip arthroplasty and its relationship with the hip function scores. METHODS:Forty-eight hips from 48 patients undergoing primary hip arthroplasty from July 2013 to August 2014 in the First Affiliated Hospital of Suzhou University were enrol ed. According to the serum level of vitamin D, patients were assigned to low-level (<20μg/L) and high-level (20≥μg/L) groups. The general information of patients, the hip function scores before and after replacement at the last fol ow-up in the two groups were observed and compared. The relationship between the serum level of vitamin D and the hip function scores before and after replacement was analyzed by multiple linear regression analysis. And the average fol ow-up was 12 months (11-14 months). RESULTS AND CONCLUSION:(1) The incidence of low vitamin D level was 82%(20 ng/mL serving as standard). (2) Compared with patients with high vitamin D level, patients with low level of vitamin D had lower preoperative Harris scores and Merle D′Aubigne-Postel score (P<0.05), and also at the last fol ow-up (P<0.05. (3) Based on the preoperative and postoperative Harris, the multiple linear regression analysis showed that there was a positive correlation between the level of vitamin D and Harris score both preoperatively and postoperatively (P<0.05). (4) These results suggest that there is a higher incidence of low level of vitamin D in patients undergoing arthroplasty, and hip function scores before and after replacement in patients with low level of vitamin D are lower than the high level patients. Moreover, there is a positive correlation between the level of vitamin D and the hip joint function scores. Therefore, it is advisable to supplement vitamin D and calcium preoperatively, and the level of vitamin D wil be helpful for disease assessment and prognosis.

Objective To compare the efficacies of medicated thread moxibustion plus needle picking therapy versus medication for sciatica.Method Seventy sciatica patients were randomly allocated to a treatment group of 35 cases and a control group of 35 cases. The treatment group received medicated thread moxibustion on Zusanli (ST36), three cones once daily and needle picking at Yanglingquan (GB34) and Huantiao (GB30), once daily. The control group took quick-acting sciatica pills, two pills twice daily. One course of treatment consisted of 10 days in both groups. The therapeutic effects were compared between the two groups of patients after two consecutive courses of treatment.Result Posttreatment pain score decreased more markedly in the treatment group (P<0.01). The total efficacy rate was 88.6% in the treatment group and 57.1% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Medicated thread moxibustion plus needle picking therapy for sciatica is more effective in relieving pain and raising the total efficacy rate.

This study was aimed to observe effects ofDendrobium ofifcinaleKimura et Migo on cardiac function and changes of blood vessel in rabbits with coronary heart disease (CHD).Thirty clean grade healthy rabbits were randomly divided into 5 groups, which were the control group, model group,Dendrobium low-dose (DLD), middle-dose (DMD), and high-dose (DHD) group, with 6 rabbits in each group. Constrictor ring was implanted in the left coronary artery to establish CHD model in the model group, DLD, DMD and DHD groups. Intragastric administration of Dendrobium decoction at the dose of 10, 20, and 40 g·kg-1 was given to rabbits in the DLD, DMD and DHD groups once a day for 21 consecutive days, respectively. The same volume of normal saline was given to the control group and the model group. Detections were made on levels of IL-8, TNF-α, VCAM-1, ICAM-1, the expression of actin, changes of LVSP, LVEDP,±dp/dtmax, BPs, BPd and morphologic changes of blood vessel. The results showed that compared with the control group, levels of IL-8, TNF-α, VCAM-1, ICAM-1 and the expression of actin increased or significantly increased in the model group with statistical significance (P< 0.05, orP< 0.01); LVEDP increased significantly (P< 0.01). However, LVSP,±dp/dtmax and BPs reduced (P< 0.05, orP< 0.01). The blood vessel wall became thicker. Compared with the model group, IL-8, TNF-α, VCAM-1, ICAM-1 and the expression of actin in the DMD and DHD group reduced or significantly reduced with statistical significance (P< 0.05, orP< 0.01); LVEDP reduced significantly in the DMD and DHD group with statistical significance (P< 0.01). While, LVSP,±dp/dtmax and BPs increased or significantly increased with statistical significance (P< 0.05, orP< 0.01). The thickening of blood vessel wall was inhibited. It was concluded thatDendrobium ofifcinale Kimura et Migo can improve cardiac function, which may take effect by improving and inhibiting pathologic changes of blood vessel and alleviating vessel injury.

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 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.

Abstract In April 2021, type Ⅰ vaccine-derived poliovirus (VDPV) was detected from two fecal samples of a male infant with acute flaccid paralysis (AFP) in Zhejiang Province when he was admitted to the Children's Hospital Affiliated to Fudan University in Shanghai, with 12 and 14 nucleotide mutations in the VP1 region, respectively. The case had a history of immunization with three doses of poliovirus vaccines, and grade Ⅲ proximal muscle strength and grade Ⅱ distal muscle strength of the right lower limb. After symptomatic treatment, the activity of the right lower limb and the muscle strength was significantly restored, thus he was discharged. VDPV was not detected from subsequent (the 8th to 12th) fecal samples of the case and fecal samples of close contacts. No similar cases were found in medical institutions in the county, surrounding areas, neighboring villages or towns. Since the case did not exhibit clinical symptoms of poliomyelitis caused by VDPV, poliomyelitis was excluded, and the case was diagnosed with hemophilia type A based on the epidemiological investigation, laboratory tests, and the history of poliomyelitis vaccination. This event involved cross-provincial (municipal) cooperation and was responsed promptly, preventing further spread of the virus. It suggested that the sensitivity of the AFP case surveillance system should be maintained, environmental monitoring methods should be increased, and the poliomyelitis vaccination should be promoted to prevent the spread of the virus.

This study was aimed to observe the effects of acupuncture combination with medicated thread moxibustion ofZhuang nationality medicine on neurotransmitters in rats with sleep deprivation. A total of 80 SPF grade healthy Wistar rats were randomly divided into the control group, model group, treatment group and diazepam group with 20 rats in each group. The establishment of insomnia model was through sleep deprivation in the model group, treatment group and diazepam group. Based on the treatment of the model group, the treatment group was treated by acupuncture combination with medicated thread moxibustion ofZhuang nationality medicine, once a day for continuous 14 days. Intragastric administration of diazepam according to 3 mg·kg-1 body weight was given in the diazepam group. While intragastric administration of the same volume normal saline was given to the control group once a day for continuous 14 days. And then, the levels of orexin, NE, 5-HT, CRH and ACTH were detected. The expressions of orexin mRNA and c-Fos were observed. The results showed that compared with the control group, the levels of orexin, ACTH, 5-HT, NE and CRH increased or obviously increased in the model group with significant difference (P < 0.05, orP< 0.01). The expressions of orexin mRNA and c-Fos in the model group were increased or obviously increased with significant difference (P < 0.05, orP< 0.01). Compared with the model group, the levels of orexin, ACTH, 5-HT, NE and CRH reduced or obviously reduced with significant difference in the treatment group (P < 0.05, orP < 0.01). The expressions of orexin mRNA and c-Fos were reduced or obviously reduced with significant difference in the treatment group (P <0.05, orP < 0.01). It was concluded that acupuncture combination with medicated thread moxibustion ofZhuang nationality medicine took an effect on the treatment of insomnia by mediating neurotransmitters associated with hypothalamic-pituitary-adrenal axis (HPA axis) through orexin, which was probably related with its therapeutic mechanism.
