Objective To evaluate the clinical efficacy and safety about carbon dioxide fractional laser combined with liquid nitrogen cryotherapy for flat warts.Methods Eighty-three patients with flat warts were divided into 2 groups according to the treatment method,42 patients in treatment group were treated by carbon dioxide fractional laser combined with liquid nitrogen cryotherapy,41 patients in control group were treated by liquid nitrogen cryotherapy alone.As a period for 10 days,2 groups were given 2 periods of treatment.The therapeutic effect,recurrence rate and adverse reaction were compared between 2 groups.Results The cure rates of 1-period and 2-period in treatment group were significantly higher than those in control group [73.81％(31/42) vs.46.34％(19/41) and 97.62％(41/42) vs.75.61％(31/41)],the recurrence rate and incidence of adverse reaction in treatment group were significantly lower than those in control group [2.44％(1/41) vs.19.35％(6/31) and 9.52％(4/42) vs.31.71％(13/41)],there were statistical differences (P ＜ 0.05 or ＜ 0.01).Conclusion Carbon dioxide fractional laser combined with liquid nitrogen cryotherapy for fiat warts is a safe and effective treatment with low recurrence rate.

OBJECTIVE:To study the therapeutic effect of compound glycyrrhizin(CG)combined with acyclovir in the treatment of herpes zoster.METHODS:98patients with herpes zoster were randomly divided into the treatment group CG+acyclovir and the control group(acyclovir).RESULTS:The regression time of the symptoms and signs in the treatment group after treatment was significantly shorter than that of the control group(P

OBJECTIVE: To explore the reasons and treatments of recurrent or residual cholesteatoma in middle ears after operations. METHOD: The clinical data of 102 cases (105 ears) with recurrent or residual cholesteatoma was retrospectively analyzed. RESULT: The main reason of recurrent or residual cholesteatoma is incomplete removal of cholesteatoma in the former operations or obstructive drainage of middle ears after operations. Twenty ears healed through cleaning with otoendoscope. Eighty-five ears underwent the second operations of radical mastoidectomy including 23 tympanoplasty meanwhile. The air-conductive auditory threshold of them all decreased more than 15 dBHL. CONCLUSION For the ears with low facial ridges and non-obstructive drainage of mastoid, tympanic antrum and tympanic cavity, its possible to be cured through cleaning with otoendoscope. For those with high facial ridges and obstructive drainage , it's essential to perform the second operations of radical mastoidectomy and some of them are suitable for tympanoplasty meanwhile.

Objective:To observe the clinical efficacy of Heweishupiyin decoction in the treatment of functional dyspepsia (FD) in elderly patients with liver stagnation and spleen deficiency.Methods:A randomized controlled method was performed in this study, and 70 FD patients were selected from February 2018 to June 2019 in accordance with the inclusion criteria.The patients were divided into the observation group and the control group according to the random digital table method, with 35 cases in each group.The observation group was treated with Heweishupiyin decoction, the control group was given mosapride citrate tablets.The period of treatment was 4 weeks.The changes of total symptom scores, TCM syndrome evaluation, electrogastrogram (EGG) parameters, serum serotonin, and Hamilton depression scale (HAMD) scores before and after treatment were recorded.The statistical analysis was performed to evaluate the clinical efficacy of Heweishupiyin decoction.Results:After treatment, the overall symptom scores in both two groups were decreased.The overall symptom score of the observation group after treatment[(8.03±4.23)points] was lower than that of the control group[(10.36±4.67)points], and the difference was statistically significant( t=2.145, P<0.05). The overall efficacy of TCM symptoms of the observation group was 88.2% (30/35), which was significantly higher than 72.8% (24/35) of the control group ( Z=-2.473, P<0.05). After treatment, the EGG parameters of two groups had different degrees of increase, the main frequency of the observation group after meal[(3.39±0.34)cpm] was higher than that of the control group[(3.18±0.36)cpm], the difference was statistically significant( t=-2.202, P<0.05). The percentage of normal slow wave in the observation group[(68.91±4.79)%] was higher than that in the control group[(66.33±3.00)%], and the difference was statistically significant( t=-2.549, P<0.05). The reaction area of the observation group[(99.09±13.58)μV/s] was higher than that of the control group[(90.27±14.70)μV/s], and the difference was statistically significant( t=-2.390, P<0.05). After 4 weeks of treatment, the HAMD score of the observation group[(14.94±2.42)points] was lower than that of the control group[(16.94±4.29)points], and the difference was statistically significant( t=2.355, P<0.05). The serum level of serotonin after treatment in the observation group[(110.46±16.69)μmol/L] was higher than that in the control group[(99.04±19.86)μmol/L], the difference was statistically significant( t=-2.551, P<0.05). Conclusion:Heweishupiyin decoction is superior to mosapride citrate tablets in improving the overall symptomatic efficacy and TCM syndrome efficacy of FD patients with liver stagnation and spleen deficiency.Heweishupiyin not only can improve the depression state of FD in the elderly, but also has the effect of improving the gastric electrical rhythm disorder, which may be related to the regulation of serum serotonin levels.

Objective To investigate the clinical effect of facial dermabrasion by microcrystal combined with red blue light in the treatment of acne pitting scar.Methods Selected from June 2013 to April 2016 hospital dermatology outpatients,98 cases of facial acne pitting scar were retrospectively analyzed,in which 50 cases of patients with facial acne dermabrasion were treated with red and blue light treatment (combined group),48 patients only choose facial acne dermabrasion treatment (control group),then treatment effect was compared between the two groups.Results At 3 months after operation,the ECCA score and mean sag depth of the two groups were significantly lower than those of the preoperative (t=23.208 and 18.586,P＜0.001).The ECCA score of the combined group was significantly lower than that of the control group (t=7.039,P＜0.05);The healing rate was 80％,which was significantly higher than those in the control group (56.25％) (x2 =6.387,P＜0.05);after 1 months and 3 months;the subjective satisfaction scores of the patients in the combined group were significantly higher than those in the control group (t=3.318 and 3.776,P＜0.05);Patients in the combined group were significantly earlier than the control group (t =4.419,P＜0.05);the incidence of edema and erythema was significantly lower in the combined group than in the control group (x2 =5.096,P＜0.05).Conclusions Facial acne dermabrasion by microcrystal combined with red and blue light treatment is superior to the single use of dermabrasion.

Objective  To study the effects of fine particulate matter(PM_2.5) on the autophagy in human melanocytes. Methods PM_2.5 was collected in Huanggang city. Then the water-soluble extracts and non-water-soluble extracts were isolated and the melanocytes were exposed to a W-PM_2.5 or NW-PM_2.5 with various concentrations. Autophagy of melanocytes was observed by MDC staining, and the expression of LC3-II /I were detected by immunohistochemistry and western blot. Results With the increase of concentration of W-PM_2.5 and NW-PM_2.5, the expression of melanocyte autophagosome and LC3-II /I increased, and the autophagy response was significantly enhanced（P<0.01）.In addition, the results of western blot showed that, at the same concentration, NW-PM_2.5 components had a stronger effect on promoting LC3II/I expression than W-PM_2.5 components（P<0.01）.Conclusion PM_2.5 can induce oxidative stress injury and excessive autophagy of melanocytes.
