Clinical Medicine of China 2017;33(9):843-846
Objective To analyze the curative effect of posterior internal fixation and fusion on patients with spinal fractures, and to provide the basis for clinical application. Methods A total of one hundred and eighty?eight patients with orthopedic incision treated in the First Affiliated Hospital of Xinxiang Medical University from March 2013 to December 2016 were divided into the observation group ( 98 cases with posterior internal fixation fusion ) and the control group ( 90 cases with anterior internal fixation fusion ) . The clinical curative effects of the patients ( including Cobb angle,spinal nerve function,complications and the success rate of surgery ) , postoperative visual analogue score ( VAS ) , hospitalization time, operation time were compared. Results In the observation group,the VAS score before operation was (6. 89±6. 89) points and reduced to (2. 70±1. 33) points after operation,the pain decreased significantly after treatment (t=26. 099,P<0. 001). The VAS score of the control group lowered from (6. 85±6. 85) points to (5. 05±1. 35) points,and the pain decreased significantly after treatment ( t=10. 704, P<0. 001 ) , and the postoperative pain in the observation group was significantly reduced than that in the control group ( t=12. 016,P<0. 001) . There were significant differences between the observation group and the control group in operation time,intraoperative blood loss,incision length and hospitalization time ( ( 141. 91 ± 35. 42 ) min vs. ( 198. 82 ± 38. 61 ) min, ( 509. 72 ±113. 65) ml vs. (823. 40±108. 54) ml,(10. 25 ± 0. 84) cm vs. (18. 83±1. 58) cm,(10. 59±12) d vs. (15. 37±1. 52) d,t=10. 541,19. 315,47. 015,24. 681,P<0. 001) . The total effective rate of the observation group was 86 cases ( 97. 96%) , and ineffective rate of the observation group was 2 cases ( 2. 04%) . In the control group, the effective and ineffective rates were 75 cases ( 83. 33%) and 15 cases ( 16. 67%) , the difference in effective rate between the two groups was statistically significant (χ2 = 12. 202, P<0. 001 ) . Conclusion Posterior internal fixation fusion is effective in the treatment of spinal fracture,which can reduce the postoperative pain,shorten the hospitalization time,less complication and high success rate. It is suitable for clinical promotion.

Objective To investigate whether clinical,endocrine,and sonographic characteristics of infertile women with polycystic ovary syndrome (PCOS) could predict the ovarian response to clomiphene citrate (CC) medication.Methods A prospective study was conducted,85 women with PCOS were given CC 50 mg per day for 5 days.In the case of an absent response,doses were increased to 100 daily in subsequent cycles.Clinical,endocrine,and sonographic characteristics were compared between responders and nonresponders.Results The cycle history (oligomenorrhea or amenorrhea) and antral follicle count (AFC) were significantly different in responders from those in nonresponders (P < 0.05).There were no differences in age,serum testosterone,follicle stimulating hormone (FSH),luteotropic hormone (LH),body mass index (BMI),insulin resistant index (HOMA-IR),and glucose and insulin levels between the two groups (P > 0.05).In addition,multivariate logistic regression analysis indicated that cycle history and AFC were the predictors of ovarian response to CC treatment.Conclusions The cycle history and AFC can be used as the simple and effective parameters to predict ovarian response to CC treatment in PCOS patients.

AIM:To investigate matrine-induced apoptosis of human medulloblastoma D 341 cells and the ex-pression of Bax , Bcl-2, serine/threonine kinase Akt and phosphorylated Akt ( p-Akt) in vitro.METHODS: D341 cells were divided into experimental groups ( added with matrine at different concentrations ) and control group ( under the same conditions without matrine).The proliferation of D341 cells was analyzed by CCK-8 assay.Apoptosis was detected by An-nexin V-FITC/PI double staining and the expression of Bax , Bcl-2, Akt and p-Akt was detected by Western blotting .RE-SULTS:Matrine significantly inhibited the proliferation of D 341 cells and increased the apoptosis in a dose-and time-de-pendent manner .The cell apoptosis was characterized by chromatin condensation with margination of chromatin to the nu -clear membrane , increased when and larger cytoplasmic vacuoles , and formation of apoptotic body after treatment with ma-trine.The expression of Bax increased , while the expression of Bcl-2 and p-Akt decreased when the drug concentration gradually increased .CONCLUSION:Matrine induces the apoptosis of human medulloblastoma D 341 cells in vitro by acti-vation of Bax, down-regulation of Bcl-2 and reduction of p-Akt expression level in the PI3K/Akt signaling pathway.

Objective: To review the clinical effect of early enteral nutrition in patients with carcinoma of esophagus after operation.Methods: Nutrient canal was indwelt through Fresubin(TP) was given through the nasal-intestinal tube in 120 cases with carcinoma of esophagus after operation.Results: The complications such as anastomotic leakage,lung infection and incisional infection in the patients receiving early enteral nutrition were much less than those in control group.No death occurred.The time for bowel function recovery was much shorter.Conclusion: Early enteral nutrition can promote the recovery of gastrointestinal function,improve the nutrition,decrease the occurrence of complications and raise the successful rate of operation in operative patients with esophagus carcinoma.
