ABSTRACT
Objective@#To analyze the clinical features of perianal condyloma acuminatum in HIV infected men who have sex with men (MSM) and assess the effects of combined treatment of microwave and photodynamic therapy.@*Methods@#Clinical and laboratory data of 260 male patients with perianal condyloma acuminatum were collected and microwave combined with photodynamic therapy was applied on them.@*Results@#The majority of the patients with perianal condyloma acuminatum were young people (243/260). Warts were mainly located in the anus or from the outside to inside of the anus (245/260). Among them, the proportion of warts position of extraanal in HIV-infected group (8/220) was lower than that of non-HIV-infected group (7/40). HPV types 11 (70/118), 6 (44/118) and 16 (40/118) were the most common types of HPV infection. People with HIV infection were more likely to develop high-risk, mixed types HPV infection and multiple HPV infection than those without HIV infection. More than half of the patients (146/260) needed only 1-3 sessions of photodynamic treatments. There was no significant difference in the times of photodynamic treatments and the numbers of photosensitizers required between the HIV-infected and non-HIV-infected groups. The recurrence rate of HIV-infected group (13.6%, 30/220) was also similar to that of non-HIV-infected group (15.0%, 6/40), but far lower than those who underwent microwave therapy alone (45%, 18/40).@*Conclusions@#The combination therapy significantly reduced the recurrence rate of perianal condyloma acuminatum in HIV infected MSM.
ABSTRACT
OBJECTIVE： To prepare pogostone transfersomes， and to evaluate its quality. METHODS： Film dispersion method was used to prepare pogostone transfersomes. Using the accumulative penetration volume （Qn） and accumulative penetration ratio （PR） of pogostone as evaluation indexes， the types of surfactant， formulation were screened in respects of the dosage of surfactant and the dosage of pogostone. The pogostone transfersomes were prepared with optimal formulation； the morphology， particle size distribution and Zeta potential were observed and the entrapment efficiency was measured. RESULTS： The optimal formulation was as follows as the sodium cholate was selected as surfactant； the dosage of sodium cholate was 0.25 g； the dosage of pogostone was 15 mg. The optimal pogostone transfersomes were ivory-white suspension； average particle size was （115.6±3.65） nm （RSD＝3.20％，n＝3）； PDI was 0.185±0.008 （RSD＝4.30％， n＝3）； Zeta potential was （－13.76±0.225） mV （RSD＝1.70％，n＝3）； entrapment efficiency of pogostone was （46.01±0.40）％ （RSD＝0.87％，n＝3）； Qn was （378.76±0.61） μg/cm2 （RSD＝0.20％，n＝3）； PR was （89.02±0.96）％ （RSD＝1.10％，n＝3）. CONCLUSIONS： Prepared pogostone transfersomes are in line with quality requirements， which can provide reference for the further study of new dosage form of pogostone.
ABSTRACT
OBJECTIVE:To observe analgesia,sedation effects and safety of flurbiprofen axetil combined with hydromorphone for postoperative patient-controlled intravenous analgesia (PCIA) after orthopedics surgery. METHODS:Totally 90 patients with combined spinal epidural anesthesia underwent lower limb surgery were selected from anesthesology department in the Affiliated Hospital of Chengde Medical College during May 2016-Jan. 2018. They were divided into SF group,H group and KH group according random number table,with 30 cases in each group. The postoperative PCIA pump drug liquid formula of SF group included Sufentanil citrate injection 2-3 μ g/kg+Tropisetron hydrochloride for injection 10 mg+0.9% Sodium chloride injection diluted to 100 mL;that of H group included Hydromorphone hydrochloride injection 0.12 mg/kg+Tropisetron hydrochloride for injection 10 mg+0.9% Sodium chloride injection diluted to 100 mL;that of KH group included Hydromorphone hydrochloride injection 0.12 mg/kg+Flurbiprofen axetil injection 50 mg+Tropisetron hydrochloride for injection 10 mg+0.9% Sodium chloride injection diluted to 100 mL. The operation time, intraoperative medication (epidural application frequency of additional ropivacaine,frequency of ephedrine and atropine),effective pressing times of analgesic pump and the analgesic effect of PCIA were observed in 3 groups. VAS score and Ramsay sedation score were observed 2,6,12,24,48 h after surgery. The hospital anxiety and depression scale (HAD) score,profile of mood states (POMS) score and the occurrence of ADR were observed before and after surgery. RESULTS:There was no statistical significance in operation time,epidural application frequency of additional ropivacaine or frequency of ephedrine and atropine among 3 groups (P＞0.05). The effective pressing times of analgesic pump in KH group were significantly lower than SF group and H group. The proportion of patients with excellent and good anesthesia effect in KH group was significantly higher than SF group and H group (P＜0.05);there was no statistical significance between SF group and H group(P＞0.05). VAS score of 3 groups 48 h after surgery were significantly lower than 6, 12,24 h after surgery;that of KH group was significantly lower than SF group and H group(P＜0.05);there was no statistical significance between SF group and H group(P＞0.05). There was no statistical significance in Ramsay score among 3 groups at different time points(P＞0.05). Before surgery,there was no statistical significance in HAD score or POMS score among 3 groups (P＞0.05). After surgery,HAD score and POMS score of KH group and H group were significantly lower than before surgery and SF group(P＜0.05);there was no statistical significance in KH group and H group,before and after surgery in SF group(P＞0.05). No vomiting,respiratory depression,pruritus and digestive tract bleeding were observed in 3 groups. The incidence of dizziness and nausea in H group and KH group were significantly lower than SF group (P＜0.05);there was no statistical significance between KH group and H group(P＞0.05). CONCLUSIONS:The flurbiprofen axetil combined with hydromorphone show good analgesic and sedative effect for PCIA after orthopedics operation,and can significantly improve emotion and mood of patients with good safety.
ABSTRACT
Drug-induced gingival overgrowth (DIGO) is characterized by fibrous gingival hyperplasia and increased gingival volume. DIGO is histologically associated with proliferation of cells and deposition of extracellular matrices, particularly collagen. Integrin α2β1 is related to collagen phagocytosis and involved in the occurrence and progression of DIGO. This paper reviews the progress of research on the relationship between integrin α2β1 and DIGO.

To evaluate whether microsurgery gains better result in root coverage compared to conventional surgical techniques. A number of databases were searched to identify eligible studies from January 1992 to January 2015. The following outcomes were evaluated: number of sites exhibiting complete root coverage and patients' esthetic satisfaction. Four Randomized Clinical Trials [RCTs] fulfilled the inclusion criteria. A pooled estimate from the two RCTs regarding sub-epithelial connective tissue grafts [SCTG] showed significant achievement in complete root coverage in the microsurgical group [relative risk [RR]:1.63; 95% confidence interval [Cl]: 1.12 to 2.36; P=0.01] with acceptable heterogeneity. The other two studies were about coronal advanced flap [CAP] with enamel matrix derivative or free rotated papilla autograft and did not qualify for meta-analysis. Patients' esthetic satisfaction was analyzed only by one study. Using microsurgical technique for treating gingival recessions may be effective in achieving complete root coverage for SCTG
