Objective To investigate the correlation between vitamin E and community acquired pneumonia (CAP) .Methods A total of 128 cases of CAP(CAP group) and 135 people undergoing the healthy physical examination (excluding CAP ,control group) in our hospital from Jan .2016 to Dec .2016 were chosen .Each group was divided into the age subgroups of 0-17 years old ,18-40 years old and 41-65 years old .Vitamin E ,Chlamydia pneumoniae(CPn) and mycoplasma pneumoniae(MP) were detected in all the subjects .Then the obtained data were statistically analyzed .Results The average vitamin E was (15 .43 ± 4 .37)mg/L in the control group and (6 .37 ± 3 .24)mg/L in the CAP group ,the difference between the two group was statistically significant(P<0 .05) .In the control group ,there were 7 cases of MP positive and 6 cases of CPn positive .In the CAP group ,there were 32 cases of MP posi‐tive and 25 cases of CPn positive .The differences of MA and CPn positive between the two groups were statistically significant(P<0 .05) .The vitamin E levels in the 0 -17 years old ,18 -40 years old and 41 -65 years old subgroups of the control group were (14 .75 ± 4 .12) ,(16 .42 ± 4 .35) ,(16 .42 ± 4 .35)mg/L respectively ,while which in the various subgroups of the CAP group were (5 .43 ± 3 .18) ,(7 .74 ± 3 .65) ,(7 .74 ± 3 .65)mg/L respectively ,the difference in different age groups between the two groups was statistically significant(P<0 .05) .Conclusion Maintaining a high level of serum vitamin E level could effectively prevent CAP .

Objective:To investigate the effectiveness of scanning glucose monitoring system in dawn phenomenon of patients with type 2 diabetes mellitus (T2DM) based on continuous glucose monitoring system (CGMS) .Methods:A total of 45 patients with T2DM hospitalized in the Endocrine Department of Xinxiang Central Hospital from June 2019 to June 2020 were selected as the research subjects by convenience sampling method. All selected patients were asked to wear the scanning glucose monitoring system after admission, and then the CGMS for continuous glucose monitoring after 48 hours. The scanning glucose monitoring system and the CGMS were taken off at the same time after 72 hours. The blood glucose analysis report of the same period was checked to determine whether the dawn phenomenon occurred. The consistency to determine dawn phenomenon was analyzed between CGMS and scanning blood glucose monitoring by Kappa test. According to the CGMS judgment results, the receiver operating characteristic curve (ROC) of the scanning blood glucose monitoring system was drawn to evaluate the optimal tangent value of the night blood glucose for predicting dawn phenomenon and the next day fasting blood glucose for evaluating dawn phenomenon.Results:Among the 45 study subjects, there was no statistical difference in determining the incidence of dawn phenomena between CGMS and scanning glucose monitoring system [55.56% (25/45) vs. 46.67% (21/45) , χ 2=0.711, P>0.05]. Consistency analysis showed that Kappa value was 0.895, and the consistency of CGMS and scanning glucose monitoring system in judging dawn phenomenon was good (Kappa=0.895, 95% CI 1.130-4.883, P<0.01) . The optimal tangent value of night blood glucose for predicting dawn phenomenon was 8.31 mmol/L, and the optimal tangent value of the next day fasting blood glucose for evaluating dawn phenomenon was 7.25 mmol/L. The value of the area under the ROC curve were 0.729 and 0.803 respectively. Conclusions:Scanning blood glucose monitoring can accurately judge the dawn phenomenon. When the night blood glucose value is 8.31 mmol/L, it indicates that the dawn phenomenon may occur. When the next day's fasting blood glucose value is 7.25 mmol/L, it indicates that the dawn phenomenon may already occur.

Objective To compare the short-term clinical effects of unilateral dual-channel endoscopic discectomy(UBED)and percutaneous endoscopic intervertebral discectomy(PEID)in the treatment of L5S,Lumbar disc herniation,LDH.Methods From January 2019 to January 2021,a total of 57 cases of L5S,LDH treated by UBED or PEID were analyzed retrospectively,including 30 cases in UBED group and 27 cases in PEID group.The operation time,intraoperative fluoroscopy times,postoperative hospitalization days and surgical complications were compared between the two groups.The visual analogue scale(VAS)and oswestry disability index(ODI)were used to compare the postoperative quality of life of the two groups,and the modified MacNab criteria was used to evaluate the clinical efficacy in the last follow-up.Results The operation time of UBED group and PEID group was(75.30±8.44)minutes and(68.37±4.63)minutes,respectively,and the difference between the two groups was statistically significant(P＜0.05).VAS and ODI of 1 week,3 months,1 year and 1.5 years after surgery in 2 groups were significantly decreased compared with those before surgery,with statistical significance(P＜0.05).The VAS score of low back pain in UBED group was higher than that in PEID group[(3.87±1.14)points vs(2.70±0.67)points]at 1 week after surgery(P＜0.05),and there was no significant difference in VAS and ODI at the other time points(P＞0.05).There was no statistical difference in the results of modified MacNab criteria in the last follow-up(P＞0.05).There were 2 cases of dural tear in PEID group,1 case of dural tear in UBED group and 1 case of temporary nerve root injury in PEID group after operation,all of which were cured after symptomatic treatment.Conclusion Compared with PEID,UBED has a longer operation time,more trauma and more obvious low back pain in the short term after operation.The short-term curative effect of the two operations on L5S1 LDH is similar,the incidence of complications is low,and the times of fluoroscopy are few.Both operations are safe and effective.
