OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

Objective To demonstrate the effect of comprehensive treatment under nasal endoscopy for epistaxis. Methods The bleeding sites of 92 patients were defined by nasal endoscopic examination. Epistaxis was cured by single pole or bipolar coagulation, combined with micro packing and systemic treatment. The bleeding sites and effect were studied retrospectively. Results The hemorrhagic foci were found in the following sites: 60.87%(56/92) in Little area, 13.04%(12/92) in the middle and back of nasal septum, 10.87% (10/92) in olfactory sulcus, 8.70% (8/92) in middle turbinate , 3.26% (3/92) at the top of inferior meatus, 2.17% (2/92) at the top of nasal cavity, 1.09% (1/92) at unknown part at the back of nasal cavity. Epistaxis was successfully controlled by once nasal endoscopic examation and hemostasis in 86 of 92 patients. While in 5 of 92 patients, epistaxis was cured by twice nasal endoscopic examation and hemostasis. Endoscopicligation of the sphenopalatineartery was performed in 1 patient with unknown posteriorepistaxis. In 92 patients,15 cases were given micro packing combined with systemic treatment. All the patients were cured and were followed up for 3 months without recurrence and the cure rate was 100.00%. Conclusions The major bleeding site is Little area. Single pole or bipolar coagulation, combined with micro packing and systemic treatment under nasal endoscope is effective for epistaxis and worth of clinic application extensively.

Objectiye To optimize the depth of the microchannel and the time point for sperm collection,and improve the efficiency of sperm screening on a microfluidic device. Methods Microchannels with four different depths of 25, 50, 100 and 200 μm were tested. Mice sperm were added to the inlet of the microchannel. The relative quantity and motility of sperm in the outlet were recorded at different collection times, i.e. ,5, 15, 30 and 60 min. Statistical method one-way ANOVA and appropriate post-hoc testing were applied to analyze differences between different groups, and further to select the best-fit depth of the microchannel and the time point for collection. Results In microchannels with depths of 25, 50, 100 and 200 μm, the sperm motilities measured in each outlet were (85.4 ± 2.3)%, (85.8 ± 5.8)%,( 87. 2 ± 2. 8 ) %, (76. 5 ± 2. 8 ) % respectively with statistical significance ( F = 5.8, P ＜ 0. 05 ). No obvious differences were found among 25-100 μm channels, however the motility dramatically decreased in the 200 μm group. The relative sperm quantities were (5.2 ±2.0)%, (7.2 ±2.5)%,(12.3 ±2.0)%,(7. 7 ± 1.1 ) % respectively with statistical significance ( F = 6. 9, P ＜ 0. 05), which increased with channel depth from 25 to 100 μm,while it decreased in the 200 μm channel Taking 2 indexes into account, 100 μmwas the most fit channel depth for sperm motility screening. The sperm motility in the outlet gradually decreased with time. At the time points of 5, 15, 30 and 60 min after adding sperm, the sperm motilities were (99. 6 ±0. 7)%, (87.2 ±2. 8)%, (79. 3 ±2. 2)% and (62. 6 ±8.0)% respectively with statistical significance ( F = 37. 3, P ＜ 0. 01 ). Yet the relative quantities of sperm in the outlet increased almost three times in this process. At the time points mentioned above, the relative quantities of sperm were (5.8±1.1)%, (10.6 ± 0.9)%, (12.1 ± 1.7)%, (17.9 ± 3.4)% respectively with statistical significance ( F = 17.8, P ＜ 0. 01 ). Thus 15-30 min was the ideal screening time. Conclusion An effective microdevice for sperm screening with optimized depth and collection time period is developed,which may contribute significantly for the screening of healthy sperm on microfluidic chips.

The prevalence rate of snoring in the elderly with hypertension and poor quality of sleep was higher than that in the normal elderly.CONCLUSIONThe prevalence of snoring in the elder persons (≥60 years) in Yangpu District of Shanghai City is high. Obesity is a significant risk factor of snoring. The main clinical presentations of snoring in the elderly are atypical by the performance of poor sleep quality and the complication of hypertension.

OBJECTIVETo analyze the efficacy and safety of bicyclol combined with thymosin in treatment of chronic viral hepatitis B (CHB).

METHODSA total of 135 patients with CHB were randomized into experimental group and control group. The patients in the experimental group received bicyclol orally 75 mg daily and thymosin 20 mg intramuscular injection once every 2 days for 24 weeks and those in control group received bicyclol orally 75 mg daily alone for 24 weeks. The levels of serum aminotransferase (ALT/AST), HBV-DNA, HBeAg /antiHBe were observed.

RESULTSCompared with pre-treatment levels, the serum aminotransferase levels decreased significantly in both groups, but there were no statistically significant differences between them. HBeAg negative conversion rate was significantly higher in the experimental group than in the control group (35.3 percent vs.19.4 percent, P less than 0.05). HBV DNA negative conversion rate was significantly higher in the experimental group than in the control group (36.7 percent vs. 20.9 percent, P less than 0.05). No obvious adverse events which were probably related to the drugs were observed in this study.

CONCLUSIONThe combination of bicyclol with thymosin had better effect in treatment of chronic hepatitis B ias compared with bicyvlol alone.

Objective Sperm screening is an essential step in IVF procedures. The swim-up method, an assay on sperm motility, is used clinically to select the ideal sperm for subsequent manipulation. However, additional parameters, including acrosome reaction capability, chemotaxis, and thermotaxis are also important indicators of mammalian sperm health. To monitor both sperm motility and chemotaxis simultaneously during sperm screening, we designed and constructed a microdevice comprising a straight channel connected with a bi-branch channel that mimics the mammalian female reproductive tract. Methods The width and length of the straight channel were optimized to select the motile sperm. Cumulus cells were selectively cultured in the bi-branch channel to generate a chemoattractant-forming chemical gradient. Sperm chemotaxis was represented by the ratio of the sperm swimming towards different branches. Results The percentage of motile sperm was improved from ( 58. 5 ± 3. 8 ) % to ( 82. 6±2.9)% by a straight channel 7 mm in length and 1 mm in width. About 10% of sperm were found chemotactically responsive in our experiment, which is consistent with previous studies. Conclusion The combined evaluation of both sperm motility and chemotaxis was achieved for the first time, and the motile and chemotactically responsive sperm can be easily enriched on a lab-on-a-chip device to improve IVF outcome.

Objective:To study the CT manifestations of malignant hepatic perivascular epithelioid cell carcinoma (PEComa).Methods:Clinical data of nine patients undergoing surgery with histologically confirmed malignant hepatic PEComa in Yueqing People's Hospital, Wenzhou People's Hospital, and Yongjia County People's Hospital from January, 2010 to June, 2022 were retrospectively collected, including two males and seven females with a median age of 47 (43, 56) years old. The CT findings, including tumor size, shape, boundary, density, and enhancement patterns, were analyzed.Results:CT scans showed that all nine tumors were single lesions. Five tumors were located in right liver lobe, three in left lobe, and one in caudate lobe. The median tumor diameter was 5.7 (range, 3.3-16.0 ) cm. In terms of tumor shape, three were round, four were quasi-circular, and two were irregular. Eight tumors had well-defined boundaries, while one was ill-defined. Nine tumors showed uneven densities and were lower than the adjacent liver parenchyma. Four tumors had a false capsule, one contained fatty tissue, and six had necrotic and cystic changes. In the arterial phase of contrast-enhanced CT scanning, two tumors showed moderate enhancement and seven showed significant enhancement. In the portal venous and delayed phases, enhancement decreased significantly in four cases, showing a " fast-in and fast-out" pattern. In four cases, the enhancement persisted, showing a " fast-in and slow-out" pattern. One case showed no enhancement in any phase but had a strip-like enhanced vessel inside the tumor. Five cases had significantly thickened vessels around the tumor.Conclusion:The CT manifestations of PEComa are as follows: round or quasi-circular lesions with well-defined boundaries, uneven low densities, significant enhancement in the arterial phase and rapid washout or persistent enhancement in the portal venous and delayed phases.
