ABSTRACT
Objective To evaluate the quality of infectious disease surveillance data and provide scientific basis for improving data quality and health decision-making. Methods The comprehensive index of infectious disease monitoring system evaluation and the integrity, accuracy and reliability of infectious disease report data were used to evaluate the quality of infectious disease monitoring data in multiple dimensions. Results In 2021, The comprehensive evaluation index of infectious disease surveillance system was 98.40%. In terms of data integrity, 1 105 data were missing, and the incomplete rate was 1.46%; In terms of data accuracy, 1978 cases were not accurately, rate of accuracy was 26.72%; In terms of data reliability, the card reporting rate of tertiary medical institutions accounted for 67.05%, the diagnosis rate of confirmed cases was 27.74%, and the correction rate of report card was 28.48%. Conclusion The accuracy and reliability of infectious disease data are insufficient, and new methods for infectious disease monitoring data quality are expanded to make up for the lack of data quality evaluation of the current national epidemic system.
ABSTRACT
Objective:To evaluate the clinical outcomes of patients with borderline developmental dysplasia of the hip (BDDH) and cam-type femoroacetabular impingement syndrome (FAIS) after hip arthroscopy.Methods:Data were retrospectively reviewed for patients with BDDH and cam-type FAIS who underwent hip arthroscopy surgery from June 2017 to December 2019. A total of 32 patients were enrolled, with a mean age of 36.13±8.67 years (range, 20-50 years), including 15 males and 17 females. The preoperative lateral center-edge angle was 22.3°±1.6° (range 20.1°-24.7°), while the preoperative α angle was 64.1°±4.6° (range, 56.0°-69.8°). All patients were treated with arthroscopic limited acetabular plasty, labral repair, femoral osteoplasty, and capsular plication after excluding from external hip diseases by ultrasound-guided hip blocking test. The visual analogue scale (VAS), modified Harris Hip Scores (mHHS) and International Hip Outcome Tool-12 (iHOT-12) scores were used to evaluate the clinical effects.Results:All patients were followed up, and the mean follow-up time was 2.5±0.8 years (range, 2.0-4.7 years). The VAS score decreased from 6.07±1.56 to 1.96±0.92 at 1 year and to 1.86±1.01 at 2 years after operation ( F=112.64, P<0.001); the mHHS score increased from 53.87±13.04 to 86.12±8.64 at 1 year and to 88.71±8.15 at 2 years after operation ( F=101.70, P<0.001); the iHOT-12 score was improved from 40.00±7.33 to 76.27±9.50 at 1 year and to 78.67±10.31 at 2 years after operation ( F=134.91, P<0.001). The α angle improved to 40.27°±4.52° (range, 34.8°-49.7°) with significant difference ( t=9.24, P<0.001). Conclusion:Hip arthroscopy can achieve satisfied short-term outcomes in treating BDDH and cam-type FAIS with few complications and less trauma.
ABSTRACT
Objective To examine the hemostatic effect of oxytocin in laparoscopic myomectomy,and to clarify the optimal dosage of oxytocin in laparoscopic myomectomy. Methods From January 2016 to July 2017, ninety patients with myoma of uterus who underwent laparoscopic myomectomy in Tangshan Union Medical College Hospital were divided into two groups: group A and group B,45 cases in each group. In group A,the patients were given 20U oxytocin and 5％ glucose injection 250 ml via intravenous drip, and in group B, the patients were injected with 20U oxytocin on the muscular wall of uterus myoma during operation. The preoperative, postoperative basic situation, intraoperative blood loss, operation time, intraoperative and postoperative adverse reactions and the time of hospitalization were compared between the two groups. Results The average amount of blood loss during operation in group B was (76. 5±15. 8) ml,significantly lower than that in group A((99. 8±20. 7) ml),and the operation time in group B was (71. 2±10. 7) min,shorter than that in group A ((90. 1±18. 4) min) The difference was statistically significant (t=1. 788、2. 878,P<0. 05). At 5 minutes,30 minutes and 180 minutes after medication, the systolic blood pressure of patients in group A was (132. 2±1. 4) mmHg,(120. 7±5. 3) mmHg,(110. 9±1. 8) mmHg and the diastolic blood pressure was (80. 9 ±12. 5) mmHg,(71. 4±12. 6)mmHg,(70. 1±2. 8) mmHg,while the systolic blood pressure in the group B was (140. 4±11. 1) mmHg,(131. 2±4. 5) mmHg,(121. 4±11. 2) mmHg and the diastolic blood pressure was (93. 4±8. 1) mmHg,(86. 4±7. 1) mmHg,(81. 1±1. 5) mmHg,the differences were statistically significant (systolic blood pressure:Ftime=68. 57,P<0. 001;FgrouP=16. 54,P<0. 001;Finteraction=4. 34,P=0. 011;diastolic blood pressure:Ftime=45. 16,P<0. 001;FgrouP=10. 79,P=0. 024;F interaction=4. 16,P=0. 037);at the same treatment time,the systolic blood pressure and diastolic blood pressure in group B were higher than those in group A,the differences were statistically significant (P<0.05).Conclusion Laparoscopic uterine myomectomy with oxytocin hemostasis, intrauterine myoma wall injection method can significantly reduce intraoperative blood loss and shorten the operation time,the effect is obviously better than intravenous drip,and it is conducive to the operation.

ABSTRACT
Objective To explore the feasibility of using the consensus of European Working Group on Sarcopenia in Older People(EWGSOP) to diagnose sarcopenia among community-dwelling women aged from seventy to seventy-nine in Shanghai.Methods Twenty-two healthy community-dwelling women were recruited as the subject group(group S),and another ten young girls were randomly selected as the control group(group C).The anthropometry,bioelectrical impedance analysis(BIA)and dual energy X-ray absorptionmetry(DEXA)were used to evaluate the circumferences of upper and lower limbs,and the dimension of muscle mass,according to relative appendicular skeletal mass(RASM)and skeletal muscle index(SMI).The grip dynamometer and isokinetic dynamometer were used to measure the muscle strength of upper and lower limbs.The ten meters gait speed,functional reach test,timed up and go test,Berg balance scale and short physical performance battery were all applied to assess the physical performance.The criteria of EWGSOP consensus were applied to diagnose the situation of sarcopenia.Results Firstly,the average biceps circumference and fat mass of upper limbs in group S were significantly higher than group C (P＜0.01),while no significant differences were observed in the muscle mass(P＞0.05).Secondly,RASM values gained from BIA and DEXA in S group were significantly higher than C group(P＜0.05),while the SMI values of the former were significantly lower than the latter(P＜ 0.01).Thirdly,absolute grip strength,relative grip strength and other bio-mechanical indexes of lower limbs in the s group were significantly lower than the C group(P＜0.01);the relative grip strength showed significant correlation with most bio-mechanical indexes of lower limbs.Fourthly,the physical performance in group S declined significantly compared with that of the c group(P＜O.05),and no significant correlation was found between muscle strength and physical performance of upper limbs except the absolute grip strength and gait speed.The prevalence was 0％ according to the RASM index,while the prevalence was 63.6％ and 45.4％ according to the BIA and DEXA respectively.Conclusion The assessing pattern from EWGSOP consensus could not be simply copied to applying on Chinese old people due to serious difference between RASM and SMI.The combination of SMI+relative grip strength+ TUG/SPPB/Berg may be better than the classical mode of RASM+absolute grip strength+gait speed in diagnosing sarcopenia.

ABSTRACT
Aim To investigate the effects of mmLDL on the up-regulation ofα1 receptors in moues mesenter- ic arteries. Methods Mice tail intravenous injection of mmLDL was used . Vitro sensitive myograph was empl- oyed to examine Noradrenaline ( NA) induced vascular contraction on mice mesenteric artery, and the mRNA and protein expressions ofα1 andα2 receptors were an-alyzed by real-time PCR and Western blot, respective-ly. Results mmLDL significantly increased NA in-duced concentration-contractile curve, and the data of Emax and pEC50 were from ( 122. 61 ± 9. 40 )% and (5. 65 ± 0. 05 ) in normal saline ( NS ) group to (161. 01 ± 6. 90 )% and ( 6. 20 ± 0. 08 ) in mmLDL group (P tion-contractile curve induced by NA towards right. Af-ter using mmLDL, the mRNA and protein levels of α1 adrenoceptor were significantly increased, but the mR-NA and protein levels of α2 adrenoceptor were not changed. Conclusion Tail intravenous injection of mmLDL enhances the vascular expressions of α1 adre-noceptors and the contractile effects mediated byα1 ad-renoceptors.
ABSTRACT
Objective To assess the left ventricular contraction asynchrony in patients with acute myocardial infarction(AMI) by velocity vector imaging(VVI).Methods Sixty AMI patients and 40 healthy volunteers were included.Using VVI,the time to peak longitudinal systolic velocity (TL-V) was measured in the left ventricular long axis views,the time to peak radial systolic velocity (TR-V) was measured in parasternal short axis views.The deviation of the earliest and the latest TL-V and TR-V (Ts max-min) was measured,and the standard deviation of TL-V and TR-V (TS-SD) was also measured.Results ①TL-V ,TR-V of the infarcted and non-infarcted segments in patients with acute myocardial infarction were longer than those of the normal segments (P ＜0.05).②The longitudinal Tsmax-min,Ts-SD and the radial Tsmax-min,Ts-SD in infarcted patients were increased compared with the healthy volunteers (P ＜0.001).③Ts of the infarcted segments was increased in turn from the class Ⅰ to class Ⅳ of the cardiac function (P ＜0.001).Conclusions VVI could be used to assess the left ventricular contraction asynchrony in patients with AMI.VVI is a new useful method to determine the infarcted segments.
ABSTRACT
Astrocytes play a major role in the reactive processes in response to neuronal injuries in the brain. Excessive gliosis is detrimental and can contribute to neuronal damage. CD81 (TAPA), a member of the tetraspanin family of proteins, is upregulated by astrocytes after traumatic injury to the rat central nervous system (CNS). To further understand the role of CD81 in the inhibition of astrocytes, we analyzed the effects of a CD81 antibody, on cultured rat astrocytes. The results indicated that the effect worked in a dose-dependent manner with certain dosage range. It, however, reached a dosage equilibrium at a high dosage. Furthermore, anti-CD81 antibody remarkably inhibited the proliferation of astrocytes after incubation with astrocytes for different periods of time and the effect presented a time-dependent fashion. However, anti-CD81 antibody substantially inhibited the proliferation of astrocytes at low density and middle density but slightly inhibited the proliferation of astrocytes at high density, suggesting that the effect was positively correlated with the proliferative ability of astrocytes. Finally, the cell cycle of astrocytes exposured to anti-CD81 antibody was arrested in S phase at the initial stage and at G(0)/G(1) phase over time. These findings indicated that CD81 exert significant inhibitory effect, dose-dependently and time-dependently, on the proliferation of astrocytes and the effect is positively correlated with the proliferative capability of astrocytes.
