BACKGROUND: Efficacy of gap arthroplasty (GA) versus interpositional arthroplasty (IA) for temporomandibular joint ankylosis (TMJA) is rarely reported, and the treatment efficacy is still under discussion. OBJECTIVE: To systematically review the efficacy of GA versus IA in the TMJA treatment and patient's prognosis. METHODS: A computer-based online research of the databases of WanFang, CqVip, PubMed, Ovid, Embase, Clinical Evidence, Cochrance Library combined with the manual search of relevant controlled trials that compared the resurrence postoperative maximal incision opening and/or recurrence of the two methods for TMJA published before October, 2015 was performed. According to heterogeneity results, the maximal incision opening index was analyzed by random-effect model, and the two groups were subdivided into temporomandibular myofascial flap and other material groups, and then MD and 95%CI were calculated; recurrence was analyzed through fixed effect model, and OR and 95%CI were calculated.RESULTS AND CONCLUSION: According to the inclusion and exclusion criteria, a total of 18 eligible articles involving 999 patients were enrolled, and the GA and IA were conducted in 656 and 343 cases, respectively. Meta-analysis results of the maximal incision opening were as followings: MD= -1.85, 95%CI: (-3.15, -0.55), Z=2.80, P=0.005, I2=55.4%; the temporomandibular myofascial flap subgroup: MD= -0.94, 95%CI: (-1.84, -0.04), Z=2.05, P=0.040, I2=0.0%; the other material group: MD= -3.36, 95%CI: (-6.66, -0.66), Z=2.39, P=0.017, I2=67.0%. Meta-analysis of the recurrence showed that OR=1.38, 95%CI: (0.87, 2.17), Z=1.37, P=0.170, I2=14.9%. Egger test manifested that there were no publication biases in the literatures. Sensitivity test showed that only one study influenced the total combined Meta-analysis results, and the others were steady. These results indicate that the IA can markedly increases the maximal incision opening in the TMJA treatment compared with the GA, but the two methods have the similar recurrence rate. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high quality researchs.

Objective Triterpene glycosides were expected to be isolated from the sea cucumber Holothuria nobilis.Methods The crude saponins of sea cucumber were desulfated with pyridine-dioxane(1∶1),the desulfated products were separated by multi-chromatography to afford two compounds.Results On the basis of chemical methods and spectral evidences,especially 2D NMR and ESI-MS technologies,these two compounds were identified as 3-O-(3-O-methyl-?-D-glucopyranosyl(1→3)-?-D-quinovopyranosyl(1→4)-?-D-quinovopyranosyl(1→2)-?-D-xylopyranosyl)-holosta-9-ene-3?,12?,17?,25?-tetraol(Ⅰ),named as nobiliside 1a;3-O-(3-O-methyl-?-D-glucopyranosyl(1→3)-?-D-xylopyranosyl(1→4)-?-D-quinovopyranosyl(1→2)-4′-O-sulfate-?-D-xylopyranosyl)-holosta-22,25-epoxy-9-ene-3?,12?,17?,25?-triol(Ⅱ),named as nobiliside 2a.Conclusion Two compounds are new triterpene glycosides.

BACKGROUND:Elderly patients may suffer from cognitive dysfunction after arthroplasty, which easily leads to the emergence of various postoperative complications, and even leads to the death of the patient. Different methods of analgesia are used to reduce the incidence of cognitive dysfunction after lower limb arthroplasty in elderly patients. OBJECTIVE:To compare the incidence of early cognitive dysfunction in elderly patients with total knee arthroplasty under different analgesia. METHODS: A total of 82 elderly patients with total knee arthroplasty in the Liuzhou City People’s Hospital Affiliated to Guangxi University of Science and Technology from December 2013 to December 2014 were enroled in this study, equaly and randomly assigned to control group and observation group, which received general anesthesia and epidural anesthesia, respectively. At 3 days after arthroplasty, Mini Mental State Examination score, visual analogue scale score and incidence rate of postoperative cognitive dysfunction in the two groups were observed and compared. RESULTS AND CONCLUSION:No significant difference in Mini Mental State Examination score was detected between the two groups (P > 0.05), but visual analogue scale score and incidence rate of postoperative cognitive dysfunction were significantly lower in the observation group than in the control group (P < 0.05). Moreover, visual analogue scale score was an independent risk factor for postoperative cognitive dysfunction (P < 0.05). These findings suggest that regarding the effect in the early postoperative cognitive function, implementation of intravenous anesthesia or epidural anesthesia in elderly patients undergoing total knee arthroplasty does not have apparent difference. As for the incidence of postoperative analgesic effect and postoperative cognitive dysfunction, epidural analgesia is better. Through analysis, the pain is a risk factor for cognitive dysfunction after total knee arthroplasty in elderly patients.

Objective To learn the clinical efficacy and adverse effects of nimodipine combined with riva stigmine in the treatment of senile vascular dementia,and to provide effective treatment for the disease.Methods 151 elderly patients with senile vascular dementia were randomly divided into observation group (78 cases) and control group (73 cases) by using the random number table method.The control group was given nimodipine,and the observation group was given nimodipine combined with rivastigmine.The cognitive function was assessed by mini mental state examination(MMSE) scale,clinical dementia rating (CDR) scale was used to evaluate the degree of dementia,and activity of daily living (ADL) scale was used to evaluate the ability of daily activities.P300 test was performed before and after treatment for 12 weeks,and latency period (P300-PL) and amplitude (P300-A) of P300 were determined.The adverse drug reactions of the two groups were observed during the treatment period.Results After 12 weeks of treatment,the MMSE scores of the two groups were higher than before treatment,the CDR,ADL scores of the two groups were significantly lower than before treatment (t =8.353,18.289,6.627,2.463,10.681,5.201,all P ＜ 0.05).After 12 weeks of treatment,the MMSE score of the observation group [(23.17 ±3.95) points] was significantly higher than that of the control group [(19.88 ± 4.43) points],the ADL,CDR scores of the observation group were (1.47 ± 0.26) points and (39.87 ± 7.43) points,which were significantly lower than (1.80 ± 0.34) points,(41.16 ± 6.40) points of the control group (t =4.823,6.725,5.278,all P ＜ 0.05).After 12 weeks of treatment,the P300-PL of the two groups were lower than those before treatment,the P300-A of the two groups were significantly higher than those before treatment (t =12.051,6.429,2.477,2.104,all P ＜ 0.05).After 12 weeks of treatment,P300-PL of the observation group [(321 ± 39)ms] was significantly lower than that of control group [(356 ± 44) ms] (t =5.180,P ＜ 0.05).In the course of treatment,the incidence rate of adverse reaction of the control group was 9.59％,that of the observation group was 11.54％,there was no statistically significant difference (x2 =0.151,P ＞ 0.05).Conclusion Nimodipine combined with rivastigrnine can effectively treat senile vascular dementia,improve cognitive function,degree of dementia and daily activity ability of patients,the incidence rate of adverse drug reaction is low,and the therapeutic method is well tolerated with good clinical application value.
