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.

Objective To evaluate the clinical efficacy of coaxial micro-incision phacoemulsification for intraoperative floppy iris syndrome (IFIS) during cataract surgery.Methods A prospective randomized control study was conducted in 80 patients (80 eyes) taking tamsulosin more than two weeks with age-related cataract from October 2014 to October 2016.All cases were randomly divided into microincision group (MICS group) and standard incision group (SICS group),40 cases in each group.Coaxial 1.8 mm microincision cataract surgery was performed in the MICS group,and coaxial 2.6 mm standard incision cataract surgery was performed in the SICS group.The incidence and the degree of IFIS and complications were recorded during the operation.The uncorrected visual acuity (UCVA) was compared at 1 day,1 week,1 month after surgery.Results At postoperative 1 day,1 week and 1 month,UCVA was 0.83 ± 0.12,0.86 ±0.10,0.89 ±0.11 in the MICS group,and was 0.71-±0.12,0.75 ±0.11,0.83 ±0.12 in the SICS group,there were statistical differences (all P ＜ 0.05),the UCVA of MICS group was better than that of SICS group.The incidence of IFIS was 60.0％ in the MICS group,and 82.5％ in the SICS group,there was statistical difference (P ＜ 0.05).There was statistical difference on degree of IFIS between two groups (P ＜ 0.05),the degree of IFIS in the MICS group was lower than that in the SICS group.Conclusion The coaxial microincision phacoemuisification is a safe and effective surgery for the patients with cataract and high risk of IFIS.

Objective To investigate the expression profiles of bone morphogenetic protein and activin membrane-bound inhibitor (BAMBI) during the development of mouse adipose tissue. Methods The total RNA was extracted for real-time PCR for amplification of BAMBI mRNA from the suprascapular brown adipose tissue (BAT) and subcutaneous (inguinal) and visceral (gonadal) white adipose tissue (sWAT and vWAT, respectively) of mice at various embryonic and postnatal stages, as well as from isolated primary preadipocytes during differentiation. Results In BAT, BAMBI mRNA levels exhibited a transient increase, peaking at day 0 (D0) and declined thereafter. sWAT and vWAT could be isolated from mice from postnatal D21 onwards, in which BAMBI mRNA levels were the highest and decreased at 8 weeks and 6 months. BAMBI mRNA levels were also significantly reduced in primary preadipocytes isolated from vWAT after induced differentiation. BAMBI mRNA expression level was higher in vWAT than in sWAT and BAT at the same developmental stages. Conclusion BAMBI is differentially expressed in different adipose tissues and developmental stages, which supports the hypothesis that BAMBI plays a pivotal role in the development of adipose tissues.

Objective: The main ingredients and the inhibitory effects of essential oil of a compound Chinese herbal medicine Weiqi Decoction (WQD) on AGS cell proliferation were to be investigated. Methods: Chemical compounds of WQD essential oil were detected by gas chromatography and mass spectrometry analysis. Cell viability was measured by methyl thiazolyl tetrazolium method. Cell cycle distribution was detected by flow cytometry. Apoptosis and necrosis of AGS cells were determined by Hoechst 33342/propidium iodine staining. Results: Chemical analysis showed that the main ingredients of WQD essential oil were bornylene and 3-n-butylphthalide. Ligustilide, which is the effective compound of Danggui (Radix Angelicae Sinensis), was not detected in WQD essential oil. The essential oil inhibited cell proliferation in a dose- and time-dependent manner, and blocked cell cycle progression at G(2)/M stage. At the concentrations that resulted in significant inhibition of cell proliferation and cell cycle arrest, essential oil induced both apoptosis and necrosis. Conclusion: The results suggest that WQD essential oil contains some effective ingredients for treating chronic atrophic gastritis and functional dyspepsia, and also has an antiproliferative effect on AGS cells through cell cycle arrest and apoptosis promotion in vitro. Therefore, essential oil should be retained as much as possible during stewing this decoction.

The objective of this study was to investigate the specific contrast-enhanced MSCT features and predominant anatomic distribution of mediastinal malignant lymphoma. Contrast-enhanced MSCT in 31 cases of mediastinal malignant lymphomas were retrospectively evaluated by analyzing the features of size, morphology, attenuation and anatomic distribution in accordance to the ATS classification of intrathoracic lymph nodes. Nine cases of Hodgkin Disease (HD) and 22 cases of Non-Hodgkin Disease (NHL) were included. The enlarged nodes were found to be homogeneous (HD 72.7%, NHL 88.9%) and partly homogeneous with necrosis (HD 27.3%, NHL 11.1%). HD involved predominantly the lymph nodes in the areas of 2R (77.8%), 3 (55.6%), 4R (88.9%), 4L (55.6%), 5 (66.7%), 6 (55.6%), 7 (66.7%) and 10R (55.6%), while NHL often involved the areas of 2R (68.2%), 3 (54.5%) 4R (59.1%), 4L (50%), 5 (54.5%), 6 (54.5%), 7 (54.5%) and 8 (50%). The following extranodal organs were involved: pericardium (19.4%), pleura (19.4%), great vessels (6.4%), lung (6.4%), chest wall (3.2%) and breast (3.2%). Mediastinal malignant lymphoma had some characteristic manifestations and predominant anatomic distribution shown on contrast-enhanced MSCT, which can provide imaging evidences for diagnosis and for determining the tumor stage.

The purpose of this study was to describe the 16-slice detector spiral computer tomography (SCT) technique and imaging features of aortic aneurysms. We analyzed 21 patients documented aortic aneurysms, that underwent unenhanced and contrast-enhanced spiral CT with a 16-slice scanner (Sensation 16), and three-dimensional reconstructions were performed for CT scan images. The results showed that: (1) Aortic dissection (11 cases), included the true and false lumen (11 cases, 100%), intimal flaps (11 cases, 100%), intimal tear (9 cases, 81.8%) and thrombosed false lumen (5 cases, 45.5%); (2) Intramural hematoma, unenhanced CT depicted crescent-shaped areas with high attenuation extending along the walls of the aorta, no definable intimal flap, while contrast-enhanced CT showed no enhancement of attenuation in the crescent-shaped areas; (3) True aortic aneurysms (7 cases), CT revealed the size, range, thrombosis and calcification of all aneurysms; (4) Pseudoaneurysms (2 cases), the enhanced part of the inhomogeneous masses beside the aorta connected with the aorta shown on contrast-enhanced CT. Therefore, 16-slice detector SCT axial and three-dimensional images can exactly reveal the pathological and anatomical features of aortic aneurysms, and provide detailed imaging information for clinical therapy.

OBJECTIVE: To explore the oncologic efficacy of transoral endoscopic CO2 laser surgery in early glottic carcinoma. METHOD: Retrospectively study 91 patients with glottic carcinoma (9 Tis, 45 pT1a, 25 pT1b, 12 pT2) treated in our department from October 1999 to August 2004. Surgical treatment included endoscopic CO2 laser cordectomies according to the classification of the European Laryngological Society in 2000. RESULT: According to the Kaplan-Meier method, the probability of remaining free of local recurrence 5 years after primary surgery alone was 100.00% for the Tis, 93.33% for the T1a, 84.00% for T1b and 75.00% for the T2 respectively, without statistical significance of various groups by the Log-Rank tests (P > 0.05). The probability of remaining free of local recurrence 5 years after primary surgery alone was 78.57% (6/28) of tumors offended the anterior commissure, versus 93.65% (4/63) with no involvement of anterior commissure, have statistical significance (P < 0.01). The 5 year overall survival and the disease free survival were 92.72% and 84.62% respectively. Perceptive evaluation was performed with the "GRBAS" evaluation system 6 month after laser operation. All patients in the group of type I and type II had an normal voice or mild dysphonia. The patients treated with type III, type IV and type V had a mild or moderate vocal disease. CONCLUSION According to the present series, endoscopic CO2 laser surgery is an effective treatment for early glottic cancer.

This study was conducted in pursuit of the optimal imaging technique and for a primary clinical application of 16-slice multislice spiral computed tomography (MSCT) for coronary artery. Unenhanced and contrast-enhanced 16-slice SCT imaging was performed in 38 cases with retrospective electrocardiographic gating. MPR, MIP and VRT reconstruction of enhanced scan images were made in all cases, and CPR, VE reconstruction images were made in some cases. The demonstration of coronary artery was evaluated. The influencing factors of the image quality were analyzed. The results showed that the detection rates of RCA, PDA, LMA, LAD, DB, LCX and LMB were 36 (94.7%), 34 (89.5%), 37 (97.4%), 36 (94.7%), 34 (94.4%), 36 (94.7%), 34 (89.5%) on axial images, respectively, which were higher than those of the arteries on 3D images (P < 0.01). Therefore, 16-slice spiral CT is a reliable and accurate technique to demonstrate coronary artery and its branches, and is a noninvasive method to screen, diagnose and postoperatively evaluate coronary artery diseases. The factors influencing the image quality include the heart rate, the cardiac rhythm, the respiratory movement of patients and the trigger delays of imaging processing.
