Objective: To observe the clinical effect of Tuina for stiffneck. Methods: All of 216 cases with stiff neck were randomly allocated into a tuina group (110 cases) and a control group (106 cases). The patients in the tuina group were treated with Three Parts, Four Points,Five Manipulation tuina therapy, while those in the control group were treated with pucturing Wailaogong (Ex-UE 8), Houxi (SI 3), Jianjing (GB 21) and Ashi points in the affected side,Once a day, and 3 times constitute one treatment course. The effect was observed after 2-course treatments. Result: The effective rate in the tuina group and the control group was 93.64% and 83.02%, respectively, and there was statistical difference between the two groups (P < 0.05).Conclusion: The tuina therapy of Three Parts, Four Points, Five Manipulations is better than simple acupuncture therapy in treating stiff neck.

Objective To investigate the effect of moderate treadmill exercise together with modified hydroxyapatite chitosan composite hydrogel (CS/HA-g-CS) implantation on repair of full-thickness defects of articular cartilage in rats.Methods Full-thickness cartilage defects were drilled in the patellar groove of bilateral femoral condyles in a total of 24 male SD rats before they were randomly assigned into 4 groups.The control group (BC group) was subjected to no exercise or CS/HA-g-CS implantation;the chitosan group (CHI group) to CS/HA-g-CS implantation without exercise;the moderate treadmill exercise group (MIR group) to exercise 4 weeks after modeling without CS/HA-g-CS implantation;the CHI + MIR group to moderate treadmill exercise plus CS/HA-g-CS implantation 4 weeks after modeling.Half of the animals were sacrificed at week 8 and half at week 16 after operation.Femoral condyles were harvested for gross observation and histochemical measurement by O' Driscoll scoring system.mRNA expressions of glycosaminoglycan,collagen type Ⅱ and BMP-2 were detected by RT-PCR.Results Gross observation revealed:at 8 weeks after modeling,the CHI + MIR group was significantly better than the other 3 groups,with the BC group in the poorest (P ＜ 0.05);at 16 weeks after modeling,the BC group was significantly poorer than the other 3 groups (P ＜0.05) among which there were no significant differences (P ＞ 0.05).O 'Driscoll scoring revealed:at both 8 and 16 weeks after modeling,the CHI + MIR group was significantly better than the other 2 groups and the BC group significantly poorer than the other 3 groups (P ＜ 0.05) but there was no significant difference between the MIR and CHI + MIR groups(P ＞ 0.05).The expressions of collagen type Ⅱ,glycosaminoglycan and BMP-2 were significantly higher in the CHI + MIR group than in the other 3 groups (P ＜ 0.05) and significantly lower in the BC group than in the other 3 groups (P ＜ 0.05).Conclusions Moderate treadmill exercise together with CS/HA-g-CS implantation has significant positive effects on repair of full-thickness defects of articular cartilage in rats than merely moderate treadmill exercise or CS/HA-g-CS implantation alone.The defective cartilage repaired by moderate treadmill exercise together with CS/HA-g-CS implantation contains more collagen type Ⅱ and glycosaminoglycan and shows morphology of nearly normal cartilage.

Objective: To learn the knowledge,attitude and practice（KAP）of primary healthcare workers on influenza vaccine and 23-valent pneumonia vaccine in Xiuzhou District of Jiaxing,and to provide basis for vaccination of influenza vaccine and 23-valent pneumonia vaccine. Methods: From November 2018 to January 2019,the primary healthcare workers from eight community health service centers in Xiuzhou District were selected by multi-staged random sampling method. A self-designed questionnaire was used to investigate the KAP of influenza vaccine and 23-valent pneumonia vaccine among primary healthcare workers. Logistic regression analysis was employed to select the influencing factors for vaccination and recommendation behaviors of primary healthcare workers. Results: Totally 105 healthcare workers（95.45%）completed the survey. Among them,86（81.90%）and 76（72.38%）workers believed influenza vaccine and 23-valent pneumonia vaccine effective;87（82.85%）and 88（83.81%）workers believed the two vaccines safe;82（78.10%）and 58（55.24%）workers knew the vaccination procedures;58（55.24%）and 34（32.38%）workers knew the key recommended population of vaccines;77（73.33%）workers knew that the vaccine costs could be paid by medical insurance. The vaccination rate of influenza or（and）pneumococcal vaccine among the respondents was 27.62%,and the recommendation rate was 46.67%. The results of multivariate logistic regression analysis showed that healthcare workers who were female（OR=7.250,95%CI：1.388-37.883）,believed the two vaccines effective（OR=4.390,95%CI：1.167-16.515）,believed the two vaccines safe（OR=11.977,95%CI：2.417-59.343）and knew the payment method of vaccine cost（OR=11.945,95%CI：2.924-48.793）were more likely to vaccinate;healthcare workers who majored in public health（OR=2.641,95%CI：1.338-5.214）,believed the two vaccines effective（OR=6.944,95%CI：1.655-29.134）,knew the key recommended population of vaccines（OR=4.380,95%CI：1.125-17.053）,had vaccinated the two vaccines（OR=7.902,95%CI：1.693-36.877）were more likely to recommend. Conclusion Primary healthcare workers in Xiuzhou District have less awareness of influenza vaccine and 23-valent pneumonia vaccine,then have lower vaccination rate（27.62%）and recommendation rate（46.67%）.

Objective To evaluate the application of a self-designed handy body position scaffold in the fluoroscopy for lower limb surgery.Methods We reviewed the intraoperative X-ray films of 161 patients with lower limb fracture who had undergone intraoperative fluoroscopy using our self-made handy body position scaffold during surgery from October 2013 to May 2017.They were 105 males and 56 females,aged from 10 to 91 years (mean,39.7 years).There were 42 femoral fractures of middle or lower shaft,12 fractures of medial or lateral condyle or tibial plateau,96 tibiofibular fractures,7 ankle fractures and 4 foot fractures.The operation time,intraoperative fluoroscopy time,intraoperative bleeding,rate and time of fracture union,and complications were recorded.Results All the 161 patients completed intraoperative fluoroscopy and radiography uneventfully,indicating that the handy body position scaffold effectively maintained the body position of the affected ipsilateral lower limb.The body position scaffold was slightly deviated due to one overweight (121 kg) patient when the knee joint was flexed 90°,but the fluoroscopy and radiography was completed after adjustment of the C-arm roentgenographic machine.The operation time averaged 71.5 minutes (from 28 to 119 minutes),the X-ray exposure time 9.8 seconds (from 6 to 31 seconds),and the intraoperative bleeding 157.2 mL (from 80 to 500 mL).The 161 patients obtained follow-up for 5 to 22 months (average,14.1 months).The rate of primary union was 97.5％ (157/161).The time for fracture union averaged 8.8 weeks (from 4 to 17 weeks).Fracture nonunion occurred in one case,and delayed union in 3 cases.The final follow-ups revealed normal functional recovery of the affected knees and ankles,but no limb shortening,or no rotational,lateral or anteroposterior angulation deformity.Conclusion In the lower limb surgery,the intraoperative fluoroscopy can be completed better with the aid of our self-designed handy body position scaffold that prevents movement of the affected lower limb and lowers the risk of radiation exposure.

Objective: To explore the reliability and validity of the Chinese Pediatric Quality of Life Inventory（PedsQL）in influenza children. Methods: From January 2017 to February 2018,we selected laboratory-diagnosed influenza cases and healthy children according to age and gender ratio by stratified random sampling and systematic sampling method. We employed Chinese version of PedsQL 4.0 to investigate their quality of life,used Cronbach's α to evaluate the reliability,and used Pearson correlation coefficient, t-test,confirmatory factor analysis（CFA）and ROC curve to evaluate the validity. Results: Totally 300 influenza cases and 300 healthy children were surveyed,with 294（98.00%）and 295（98.33%）valid questionnaires recovered. The general Cronbach's α was 0.89,and the Cronbach's α of each dimension ranged from 0.79 to 0.84. The Pearson correlation coefficients between the items and their belonged dimension ranged from 0.537 to 0.755,between the items and other dimension ranged from 0.203 to 0.384. The CFA resulted in RMSEA of 0.06,GFI of 0.88,AGFI of 0.90,CFI of 0.91 and NFI of 0.89. The scores in total and in all the dimensions in influenza cases were significantly different with those in healthy children（P<0.05）. Taking the scores in influenza cases as a golden standard,the area under the ROC curve was 0. 985（P<0.05）,the sensitivity was 0.92,and the specificity was 0.95. When the limit score was 82.18,the Youden index was the largest. Conclusion The Chinese version of PedsQL4.0 has good reliability and validity, which can be applied to quality of life assessment in children.

Objective:To investigate the clinical efficacy of avatrombopag combined with recombinant human thrombopoietin (rhTPO) versus avatrombopag in the treatment of severe thrombocytopenia associated with chronic liver disease.Methods:The retrospective cohort study was conducted. The clinical data of 56 patients with severe thrombocytopenia associated with chronic liver disease who were admitted to the First Affiliated Hospital of University of Science and Technology of China from May 2020 to October 2021 were collected. There were 36 males and 20 females, aged from 33 to 74 years, with a median age of 54 years. Of 56 patients, 21 cases undergoing treatment of avatrombopag combined with rhTPO were allocated into the combined treatment group and 35 cases undergoing treatment of avatrombopag were allocated into the monotherapy group. Observation indicators: (1) changes of platelet after treatment; (2) adverse drug reaction. Follow-up was conducted using outpatient examination and telephone interview to detect changes of platelet and effects of treatment within 2 weeks after treatment. The follow-up was up to October 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and compari-son between groups was analyzed using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Changes of platelet after treatment. The platelet level within 1 to 5 days and 6 to 10 days after treatment in the combined treatment group were (35±19)×10 9/L and (73±41)×10 9/L, respectively. The above indicators of the monotherapy group were (40±30)×10 9/L and (70±51)×10 9/L, respectively. There was no significant difference in change trends of platelet before and after treatment between the two groups ( Fgroup=0.30, P>0.05). There was a significant difference in platelet count before and after treatment between the two groups ( Ftime=59.96, P<0.05). There was no interaction effect in change trends of platelet between the two groups ( Finteraction=0.40, P>0.05). The effective rates were 66.67%(14/21) in the combination therapy group and 54.29%(19/35) in the monotherapy group. There was no significant difference in the effective rate between the two groups ( χ2=0.83, P>0.05). (2) Adverse drug reaction. Cases with headache, dizziness, blood transfusion reaction, hematuria, proteinuria, fever, abdominal pain, diarrhea, dyspepsia, fatigue, nausea or peripheral tissue edema were 2, 4, 1, 2, 2, 7, 10, 6, 8, 14, 12, 5 in the combined treatment group, versus 5, 8, 1, 3, 5, 7, 19, 11,20, 19, 14, 5 in the monotherapy group, respectively. There was no significant difference in cases with headache, dizziness, blood transfusion reaction, hematuria, proteinuria between the two groups ( P>0.05), and there was no significant difference in cases with fever, abdominal pain, diarrhea, dyspepsia, fatigue, nausea, peripheral tissue edema between the two groups ( χ2=1.24, 0.23, 0.05, 1.91, 0.83, 2.04, 0.81, P>0.05). Conclusion:Both of avatrombopag combined with rhTPO and monotherapy of avatrom-bopag can be used to promote the platelet level in patients with severe thrombocytopenia associated with chronic liver disease, and avatrombopag combined with rhTPO does not provide better clinical benefits compared with monotherapy avatrombopag.

Objective: The objective of this study was to analyze the disease burden of influenza in schools and child care settings in rural areas of Hangzhou. Methods: Hospital visit influenza cases aged 3-17 years in hospitals that reported based on influenza surveillance system from 2016 to 2018 in Chun′an county, Hangzhou city were selected as study subjects and a total of 294 confirmed cases of influenza were selected using system sampling method. Questionnaires were designed to investigate the basic information and data on inpatients and outpatients among, health care and life quality, etc.. Direct and indirect economic burden and disability adjusted life year (DALY) were analyzed and compared among different age groups. Results: The mean age of investigated subjects was (8.88±3.92) years. A total of 143 (48.64%) investigated cases were male. In total of 283 (96.26%) cases were outpatients. The total economic burden was 124 743.95 CNY. The mean economic burden was 424.30 CNY per person. The mean direct and indirect economic burden was 361.33 and 62.97 CNY per person respectively. The difference of the mean direct, indirect and total economic burden per person between different age group was statistically significant (P<0.001). The 3-5 years age group showed the highest economic burden with the median value of direct, indirect and total economic burden per person being 276.24, 50.98 and 321.26 CNY, respectively, while the 12-17 years age group showed the lowest values with 175.30, 26.54, 201.79 CNY, respectively. The DALY of 294 influenza cases was 1.18, and the median of burden strength was 3.21 DALY/thousand. The difference of the burden of strength between different age group influenza case was statistically significant (P<0.001), of which the 12-17 years age group showed the highest value with 4.25 DALYs/thousand while the 3-5 years age group showed the lowest value with 2.60 DALY/thousand. Conclusion The disease burden of influenza was heavy in schools and kindergartens in rural areas of Hangzhou city, with the cases aged from 3 to 5 years showing higher economic burden and cases aged from 12 to 17 years showing greater burden strength.

AIM: To evaluate the refractive status through computer refractometer and OPD-Scan III auto refractometer in cataract patients after extended depth of focus(EDOF)intraocular lens implantation.METHODS: Retrospective observational study. A total of 61 cases(76 eyes)that received phacomulsification and implanted with TECNIS® Symfony ZXR00 intraocular lens in Shanghai Eye Diseases Prevention & Treatment Center from May 2022 to May 2023 were collected. Measurements from the computer refractometer, OPD-Scan III auto refractometer, and subjective refraction, were taken from all patients on the same day postoperatively.RESULTS: There were statistical significant difference in sphere(S)and spherical equivalent(SE)readings from the computer refractometer and subjective refraction(all P<0.01), with mean differences of -0.67±0.37 D and -0.75±0.35 D, respectively, and the S and SE obtained from computer refractometer more incline to myopia than those from subjective refraction; there were statistical significant difference in computer refractometer and subjective refraction(P<0.01), with a relative small absolute difference(0.21±0.24 D). The S, cylinder(C)and SE of computer refractometer(S, C, SE)were positively correlated with subjective refraction(r=0.7994, 0.7929, and 0.8118, respectively, all P<0.01). Additionally, there were statistical significant differences in S, C and SE of OPD-Scan Ⅲ and subjective refraction(P<0.01), and the absolute differences of S(0.63±0.36 D), C(0.35±0.26 D)and SE(0.53±0.36 D)were small. Furthermore, the S, C and SE of OPD-Scan Ⅲ were positively correlated with subjective refraction(r=0.4410, 0.4982, 0.5224, all P<0.01).CONCLUSION: In patients who received implantation of EDOF lenses, the consistency of computer refractometer, OPD-Scan III auto refractometer and subjective refraction was good. The average difference of the S and SE obtained via computer refractometer was large, but both exhibited a myopic shift relative to those derived from subjective refraction, and the C values demonstrated minimal discrepancy. Furthermore, the differences between OPD-Scan III auto refractometer and subjective refraction were small, but the direction of the difference is unstable, sometimes it is myopic deviation, while sometimes it is hyperopic deviation.
