ABSTRACT
Objective To discuss the correlation between initial malar reduction procedures and the method of revision procedures and the personalized treatment strategies for the second deformity of postoperative prominent malar complex.Methods From January 2003 to December 2017,27 patients underwent personalized revision surgery of malar reduction according to the different second deformity of malar complex.The surgical technique included the double support malar reduction technique,orthotopic malar osteotomy technique,malar bone grinding surgery,and autogenous bone transplantation.Results A total of 27 patients subjected to revision surgery for malar reduction between November 2006 and December 2017 were retrospectively reviewed.22 patients were satisfied with aesthetic outcomes after the first revision procedure,while 5 patients were satisfied after 2 or 3 procedures follow-up for 10 to 12 months.Conclusions The incidence of complications after malar reduction is related to the first surgical method.According to the unsatisfactory results,it can be repaired individually to obtain a better clinical repair effect.
ABSTRACT
OBJECTIVE: To systematically evaluate therapeutic efficacy and safety of Compound muni ziqi granules in the adjuvant treatment of chloasma, and to provide evidence-based reference for clinical treatment. METHODS; Retrieved from Chinese Journal Full-text Database (CJFD), China Scientific Journal Database (CSJD), Wanfang database, Medline and Embase, randomized controlled trials (RCTs) about therapeutic efficacy (total response rate, cure rate, the decrease level of E2, FSH and LH in serum) and safety of Compound muni ziqi granules alone or combined with routine drug (trial group) vs. routine drug (control group) in the treatment of chloasma were collected. Meta-analysis was conducted by using Rev Man 5. 3 statistical software after data extraction of clinical studies meeting inclusion criteria and quality evaluation with Cochrane systematic evaluator manual 5. 1. 0. RESULTS: Totally 12 RCTs were enrolled, involving 1 100 patients. Results of Meta-analysis showed that total response rate [OR=2. 84, 95％CI(2. 20, 3. 67), P<0. 001], cure rate [OR=2. 11, 95％CI(1. 59, 2. 79),P<0. 001],decrease level of Ez [OR=-98. 64, 95％ CI (-110. 84, -86. 44), P <0. 001], decrease level of FSH [OR=-1. 85, 95％CI(-2. 58,-1. 11),P<0. 001] and decrease level of LH [OR= - 5. 85, 95％ CI (-6. 83, -4. 87), P<0. 001] in trial group were significantly better than control group, with statistical significance. In trial group, a few patients suffered from the increase of menstruation, the decrease of menstruation, temporary pigmentation and transient burnout; but all symptoms did not affect the treatment. CONCLUSIONS: Compound muni ziqi granules show definite clinical efficacy and good response rate in the adjuvant treatment of chloasma with mild ADR.
ABSTRACT
Objective@#To present a new method for correction of prominent malar complex via intraoral approach by double support technique osteotomy which can provide a stable support.@*Methods@#According to the anatomical characteristics of malar complex and relevant masseter muscle, we designed a malar reduction technique including anterior and posterior support. The reduction procedure entailed an L-shaped osteotomy ofthemalarbody and oblique osteotomy of malar arch. On the basis of prominence degree, bone fragment was moved inward and upward to form double support, which could reduce malar and zygomatic arch effectively.@*Results@#A total of 76 patients subjected to double support technique for malar reduction between January 2015 and January 2017 were retrospectively reviewed.The follow-up period ranged from 10 to 12 months. All patients were satisfied with aesthetic outcomes without major complications, such as facial nerve damage or bone ununion.@*Conclusions@#Double support technique is an effective method to correct malar prominence andreduce the zygomatic complex which can prevent saggy cheek and bony malunion.
ABSTRACT
Objective To explore the feasibility of blood oxygen level-dependent (BOLD) MRI to detect the chronic hepatitis b-induced early kidney injury. Methods Seventeen clinically diagnosed chronic hepatitis b patients with early kidney injury and 10 healthy volunteers were enrolled in this preliminary study. The 17 patients underwent dynamic nuclear renography and then subdivided into stage 1 kidney injury group (n=7) and stage 2 kidney injury group (n=10). All of the enrolled subjects underwent BOLD examination and T2* relaxation rates (R2*) of renal cortex and medulla of split kidney, and the ratio between them (R2*med/cor) were measured separately. One-way analysis of variance (ANOVA) were performed on the control group and chronic hepatitis b patients group (kidney injury stage 1 and stage 2 group) to compare the difference of renal cortical and medullary R2*values and R2*med/cor ratio. ROC curves were used to evaluate the efficacy of renal cortical and medullary R2* values and R2*med/cor ratio to diagnose the chronic hepatitis b-induced kidney injury. Results The cortical R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were(16.87 ± 0.74)/s,(17.88 ± 0.73)/s,(20.29 ± 2.87)/s, respectively;the medullar R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were (28.07±1.03)/s,(31.14±2.49)/s,(32.81±3.28)/s, respectively;R2*med/cor of the of control group, stage 1 kidney injury group and stage 2 kidney injury group were 1.67 ± 0.09, 1.75 ± 0.16, 1.63 ± 0.13, respectively, and the differences among the three groups were statistically significant (F values were 17.779, 19.170 and 3.439 , all P<0.05). Furthermore, the renal cortical and medullary R2* values of chronic hepatitis b patients were significantly higher than the control group, and the the renal cortical R2* value of the patients in stage 2 kidney injury group was also higher than the stage 1 kidney injury group. The area under curve (AUC) of ROC of the renal cortical and medullary R2*values and R2*med/cor to diagnose chronic HBV hepatitis-induced early kidney injury were 0.903, 0.949 and 0.526, respectively. Conclusion It's feasible and has great value to use renal BOLD MRI for the diagnosis of chronic hepatitis b-induced early kidney injury, and the renal cortex is more sensitive than the medulla to the kidney injury.
ABSTRACT
Objective:To observe the effect of hemp seed oil on the blood lipid and its hepatoprotective efficacy in hyperlipidemic rats. Methods:High fat diet was used to make the hyperlipidemia model in SD rats,and the rats were randomly divided into 6 groups:the normal control group,high fat model group,high dose group(1. 5 g·kg-1 ),medium dose group(1. 0 g·kg-1 ),low dose group (0. 5 g·kg-1 )and Xuezhikang group(0. 5 g·kg-1 ). After 35-day treatment,serum TC,TG,HDL-C,LDL-C,SOD,MDA,ALT, AST and liver SOD were detected. Results:Compared with the model group,hemp seed oil at different dosages could significantly de-crease the contents of serum TC,TG,ALT and the atherogenic index(AI)( P<0. 05 or P<0. 01),and significantly increase the SOD activity in serum and liver(P<0. 01). The contents of serum MDA and AST in the medium and high dose groups were signifi-cantly decreased(P<0. 01),and the content of LDL-C in serum and the content of MDA in liver in the high dose group were signifi-cantly reduced(P<0. 01). Conclusion:Hemp seed oil shows promising blood lipid reducing ability and liver protective effect in hy-perlipidemic rats,and the mechanism may be related with liver lipid metabolism improvement and antioxidant function enhancement.
ABSTRACT
Objective To analyze the effect of bilevel positive airway pressure (BiPAP) in the patients with hypercapnia overlap syndrome (OS). Method From October 2012 to December 2014, 12 patients with complicated with hypercapnia in the presence of chronic obstructivepulmonary disease ( COPD ) and moderate to severe obstructive sleep apnea syndrome (OSAS), in the respiratory department of our hospital were treated with Noninvasive positive pressure ventilation for 10 days , blood gas was analysed and comparedbefore and after treatment. Results After BiPAP application and the day leaving hospital , pHi n each time point significantly decreased (P < 0.05), PaO2 significantly increased (P< 0.05), PaCO2 significantly decreased (P < 0.05). Conclusion BiPAP ventilation is an effective treatment in patients with hypercapnia overlap syndrome.
