ABSTRACT
Objective: To compare the efficacy of Tuina (Chinese therapeutic massage) plus physical agents and physical agents alone for lateral collateral ligament injury of ankle in gymnasts, and to explore the feasibility of Tuina for injury intervention in competitive athletes.Methods: A total of 64 gymnasts with types Ⅰ-Ⅱ lateral collateral ligament injury of ankle were selected and divided into a control group and an observation group according to a full analysis set based on the intention-to-treat principle, with 32 cases in each group. Patients in the control group received ultrasound and microwave treatment, while those in the observation group received additional Tuina manipulations. The efficacy was evaluated by total effective rate, visual analog scale (VAS) score, and American Orthopedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHS) score. Results: The total effective rate was 96.9％ in the observation group and 90.6％ in the control group. There was no statistical difference in the total effective rate between the two groups (P>0.05). The markedly effective rate was 75.0％ in the observation group and 46.9％ in the control group. The markedly effective rate in the observation group was higher than that in the control group (P<0.05). After treatment, the VAS scores of both groups showed a downward trend, and there were statistical differences between different treatment time points in the same group (P<0.05). After one and three months of treatment, the VAS scores of the observation group were lower than those of the control group (P<0.05). There were statistical differences in the AOFAS-AHS score before and after treatment within the same group (P<0.05). After one month of treatment, there was no statistical difference in the AOFAS-AHS score between the two groups (P>0.05). After three months of treatment, the AOFAS-AHS score in the observation group was higher than that in the control group, indicating statistical significance (P<0.05). There was an interaction between time and group (P<0.05). Conclusion: Tuina plus physical agents can improve the symptoms of lateral collateral ligament injury of ankle in gymnasts. This combined treatment is superior to physical agents alone in relieving pain and improving joint functions. Therefore, Tuina plus physical agents can be used as a treatment for lateral collateral ligament injury of ankle in gymnasts.
ABSTRACT
Objective:To investigate the status of viral reservoirs in prostate tissue of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), and to investigate the effect of highly active anti-retroviral therapy (HAART) on HIV-1 DNA in prostate tissue of HIV/AIDS patients.Methods:Twelve patients with HIV infection and hyperplasia of prostate who required surgical treatment and admitted to Guangzhou Eighth People′s Hospital from July 2017 to October 2019 were included. Blood and prostate specimens of these patients were collected, and HIV-1 RNA in plasma, CD4 + T lymphocyte count in peripheral blood and HIV-1 DNA level in prostate tissue were tested respectively. The independent sample t test or Mann-Whitney U test was used for statistical analysis. Results:Among the 12 patients, the CD4 + T lymphocytes was (519.8±121.5)/μL and HIV-1 DNA in the prostate tissue was 2 602 (365, 10 700) copies/10 6cells in six patients who had not started HAART. The CD4 + T lymphocytes was (182.8±69.7)/μL and the HIV-1 DNA in the prostate tissue was 144 (36, 563) copies/10 6cells in the six patients who underwent HAART for over six months. There were statistically significant differences in CD4 + T lymphocytes and HIV-1 DNA in the prostate tissue between the two groups ( t=-5.889 and Z=-2.082, respectively, both P<0.05). Conclusion:Prostate tissue can be used as an HIV-1 virus repository with or without HAART, and the size of the prostate tissue virus repository can be reduced by HAART after immune reconstitution.
ABSTRACT
At present,thyroid surgery is widely carried out during clinical practice.Because of preoperative or intraoperative misdiagnosis,nonstandard scope of operation,tumor recurrence and other factors,resulting in some cases needed to treat again.Due to the previous surgical scar adhesion and disordering of anatomical structure,the risk of injury of recurrent laryngeal nerve(RLN)increased manyfold.Intraoperative neuromointoring(IONM)is a technology for monitoring the functional integrity of the nervous system in state of dangerous by neural electrophysiological means.Better than the naked eye to identify and prompt the recurrent laryngeal nerve injury,to find the site of injury,IONM can significantly reduce the chance of transient RLN injury during thyroid reoperation as a sharp weapon to protect RLN.

ABSTRACT
Objective To explore the experiment condition and method for the application of in vitro in vasive Transwell chamber and to observe muscarinicreceptor stimulant and muscarinicreceptor antagonist's influence to cholangiocarcinoma's invasiveness.Methods Two hundred microliter cell suspension of various concentrations(0.5×105/mL,1.0×105/mL,1.5×105/mL and 2.0×105/mL)was added into the upper chamber of the Transwell chamber,and the cells were allowed to penetrate the matrigel for 12,18,24and 48 hours respectively.The numbers was gotten as the invasive cells on the under surface of the membrane.After optimal cell concentration and time were gotten,pilocarpine of various concentrations(0 mmol/L,0.1 mmol/L,0.3 mmol/L and 0.5 mmoL/L)was added into the upper chamber of the Transwell chamber,then the cells on the matrigel were stained and counted.So did the cells when atropine of various concentrations(0.01 mmol/L,0.01 mmol/L,0.05 mmoVL and 0.1 mmol/L)were added into the upper chamher of the Transwell chamber in according to pilocarpine of various concentrations(0 mmol/L,0.3 mmol/L,0.3 mmol/L and 0.3mmol/L).Results With the increase of the time and cell concentrations，the cells couts that penetrated the matrigel increased，while the increase tended to he stable when the culture time exceeded 36 hous and the cell concentration Was over 1.0×105/mL.By adding pilocarpine,there were significant differences between the control and experimental groups(P＜0.05)，but there were no significant differences in experimental groups with various concentrations.There were no significant differences in blank group and experimental groups with atropine added(P＞0.05).When added pilocarpine and atropine,there were significant differences between blank and experimental groups(P＜0.05)，but there were no significant differences in experimental groups with various concentrations.Conclusions Thirty-six hours as invasive time,and one cell concentration 1.0 × 105/mL were optimal to test invasion abilities of cholangiocarcingma cells to different medicines or reagents.There is the possibility that museariniereceptor exists in cholangiocarcinoma cells，and may play an important role in cholangiocarcinoma's invasiveness and metastasis.
ABSTRACT
Objective To investigate the role of cyclooxygenase-2(COX-2)and mitochondrial adenosine tuiphosphate sensitive potassium channels (mito-KATP channels) in sufentanil preconditioning-induced delayed cardiopreteetion against myocardial ischemia-reperfnsion (I/R) injury in rats. Methods Seventy-two adult male Wistsr rats weighing 250-300 g were randomly divided into 6 groups ( n =12 each). Group Ⅰ,Ⅱ,Ⅲ were preconditioned with intraperitoneal (IP) normal saline (NS) 1 ml/kg while group Ⅳ,Ⅴ,Ⅵ with IP sufentanil 20 μg/kg at 24 h before myocardial ischemia. Group Ⅱ and Ⅴ were given IP NS-398 ( COX-2 inhibitor) 5 mg/kg at 30 rain before myocardial ischemla while group Ⅲ and Ⅵ were given intravenous 5-HD (mito-KATP channelblocker) 10 mg/kg at 10 min before ischemia or before being killed. Six animals in each group underwent 45 min myocardial ischemia followed by 120 min reperfusion, while the other six animals in each group were killed immediately before ischemia for determination of myocardial COX-2 expression and myocardial PGF2 and PGF1α content. Myocardial ischemia was induced by occlusion of left anterior descending branch (LAD) of coronary artety for 45 rain followed by 120 min reperfusion. MAP and HR were recorded immediately before ischemia (T0), at 15, 30, 45 rain of ischemia (T1-3) and at 30, 60, 90, 120 vain of reperfusion (T4-7). Heart rate-blood pressure product (RPP) was calculated. Arterial blood samples were obtained at T0.3 and T7 for measurement of plasma CK-MB activity. The animals were killed at the end of 120 nan reperfusion. The hearts were removed for determination of myocardial infarct area (IA) and area at risk (AAR). LA/AAR was calculated. Results There was no significant difference in HR, MAP and RPP at all time points among the 6 groups. Preconditioning with sufentanil significantly decreased plasma CK-MB activity at T3 and T7 and IA/AAR in group Ⅳ as compared with group Ⅰ.Myocardial COX-2 expression was up-regulated and PGE2 and PGF1α, contents were elevated by sufentanil preconditioning in group Ⅳ as eomared with control group (Ⅰ). In group Ⅴ and Ⅳ preconditioning with NS-398/5-HD significantly increased plasma CK-MB concentration and IS/AAB as compared with group Ⅳ, indicating involvement of COX-2 and mito-KATP channels in the sufentanil-induced delayed cardioprotection.The myocardial PGE2 and PGF1α contents were significantly reduced in group Ⅴ as compared with group Ⅳ. There was no significant difference in the myocardial COX-2 expression among group Ⅳ, Ⅴ and Ⅵ. Conclusion Both COX-2 and mito-KATP channels are involved in sufentanil preconditioning-induced delayed cardiopmtection.
ABSTRACT
Objective To evaluate the influence of head anteflexion on airway sealing pressure during intermittent positive pressure ventilation(IPPV) with ProSeal laryngeal mask airway (PLMA) with an esophageal vent.Methods Fifty ASA Ⅰ or Ⅱ patients (20 males and 30 females), aged 18-51 ye are, weighing 50-70 kg and scheduled for elective plastic surgery under general anesthesia, were enrolled in this study. Anesthesia was induced with fentanyl 2 μg/kg, propofol 2 μg/kg and vecuromium 0.1 mg/kg. PLMA with an esophageal vent was inserted at 2 min after intravenous vecuronium injection.The airway sealing pressure, the anatomic position of the cuff and the efficacy of positive pressure ventilation were checked in the neutral and anteflexed head positions with the cuff deflated and inflated to an intracuff pressure of 60 cm H2 O, respectively.Results The lungs were better ventilated in the head anteflexion position than in the head neutral position whether the cuff was deflated or inflated. There was no significant difference in the volume of air required to achieve an intracuff pressure of 60 cm H2O between the two head positions ( P＞ 0.05). The airway seating pressure increased from (27 ± 6) cm H2O in the head neutral position to (33 ± 6) cm H2O in the head anteflexion position, with no significant difference between them ( P＞ 0.05). The expired tidal volume and the peak inspiratory pressure during IPPV were (496 ± 81 ) ml and (14.3 ± 1.9) cm H2O respectively in the head neutral position and (496 ± 81 ) ml and ( 14.5 ± 2.1 )cm H2O respectively in the head anteflexion position.Conclusion Head anteflexion can significantly improve airway sealing but does not affect the anatomic position of the cuff.Appropriate head anteflexion is a simple and effective way to improve IPPV when the airway sealing pressure is inadequate in the head neutral position.
