Objective To investigate the diagnostic value of serum hyaluronic acid and laminin in patients with coronary heart disease complicated with myocardial infarction.Methods 100 patients with coronary heart disease(CHD) were selected as the coronary heart disease group, and the patients with CHD and myocardial infarction(AMI) were selected as the infarct group in our hospital from July 2015 to July 2016.The levels of serum hyaluronic acid and laminin were compared between the two groups, and the levels of hyaluronic acid and laminin were analyzed.Results The expression of LN and HA in the infarction group were significantly higher than those in the coronary heart disease group(P<0.01).LN and HA expression were presented in the two groups, Coronary artery three ressel disease>double branch lesions > single vessel disease(P<0.05).LN and HA expression in different coronary artery lesions in the infarction group were significantly higher than those in the coronary heart disease group(P<0.05).The expression of LN and HA in patients with anterior and inferior wall myocardial infarction were significantly higher than those in anterior wall and inferior wall infarction(P<0.05).Conclusion The increase of serum HA and LN in patients with coronary heart disease may cause acute myocardial infarction.

Objective To study the the association of Hs-cTNT level with coronary flow in patients with ST-segment elevation myocardial infarction(STEMI) undergoing percutaneous coronary intervention(PCI).Methods130 cases with STEMI in hospital from January 2014 to December 2014 were divided into the positive group and the negative group according the level of Hs-cTNT.Multivariate analysis were used to examine the association of Hs-cTNT with coronary flow in patients with ST-Segment elevation myocardial infarction undergoing primary PCI.ResultsThe incidence of no reflow in the positive group was significantly higher than that in the negative group (P<0.05) The left ventricular ejection fraction in the positive group was significantly lower than that in the negative group (P<0.05).Multivariate analysis showed that Hs-cTNT was independently associated with coronary flow no-reflow in patients with acute STEMI post-PCI and TIMI flow fractionation events(P<0.05).ConclusionHypersensitivity troponin T is an effective marker for predicting coronary artery flow damage in patients with STEMI after PCI and evaluating risk stratification in patients with STEMI.

OBJECTIVE To analyze the complications of the CO2 laser-assisted laryngeal microsurgery for laryngeal tumors. METHODS The clinical data of 520 patients who underwent CO2 laser assisted laryngeal microsurgery for laryngeal tumors were retrospectively analyzed. The complications were recorded. RESULTS Complications caused by CO2 laser were found in 61 case(11.73 %) and those caused by suspended laryngoscope in 71 case(13.65 %). CONCLUSION The complications of the CO2 laser-assisted laryngeal microsurgery for laryngeal tumors may be caused by CO2 laser or suspended laryngoscope.

Objective To study the results of clinical application of videokymography. Methods 50 patients with voice pathology and 5 normal voice persons were studied with videokymography. Results With videokymography, left - right asymme- tries, close or open quotient differences, abnormal periocity and mucosal waves were visualized in 50 patients. The vibration of vo- cal folds was slight asymmetry in 1 normal voice person and normal in other 4 normal voice persons. Conclusion Videokymography provides a simple way to study irregular vibrations of the vocal folds. It is helpful for a more accurate diagnosis of the vocal folds. Information obtained allows a first time quantification of vibrations registered.

Objective To evaluate the results of the Groningen valve voice prosthesis in China.Methods The Groningen valve was used to date in 10 patients with a mean age at insertion of 60.2 years from January 2003 to January 2004. Seven patients underwent primary valve insertion at the time of surgery and in three patients the prosthesis was inserted at a later date. The speech quality of this group was assessed.Results The median score was 4.6(range 3.3～6.9)which compared favourably with a similar analysis of other valve.Conclusion The Groningen valve provides a highly acceptable means of obtaining vocalization after total laryngectomy in patients.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized eczema in children.Methods A multicenter,randomized,open-labeled,tacrolimus 0.03％ ointment-controlled clinical trial was conducted.A total of 442 children with localized eczema were enrolled into this study,and divided into 2 groups to topically apply Qingpeng ointment (Qingpeng group) and tacrolimus 0.03％ ointment (tacrolimus group) respectively twice a day for 2 weeks.The children were followed up before the treatment and 1,2 weeks after the treatment,and the efficacy and safety were evaluated at the same time.Results Clinical data from 426 children were included in the efficacy analysis.At 1,2 weeks after the treatment,there were no significant differences in the response rate between the Qingpeng group and tacrolimus group (1 week after the treatment:78.92％ vs.81.77％,x2 =0.545,P =0.460;2 weeks after the treatment:98.65％ vs.97.54％,x2 =0.721,P =0.396).However,the pruritus scores at 1,2 weeks after the treatment were both significantly lower in the Qingpeng group than in the tacrolimus group (1 week:F =14.001,P =0.000;2 weeks:F =11.252,P =0.001).At 1 week after the treatment,the incidence rate of adverse reactions was significantly lower in the Qingpeng group than in the tacrolimus group (P ＜ 0.05).Mild itching,burning sensation and other local irritant sensations were the most common adverse reactions.Conclusion Qingpeng ointment is safe and effective for the treatment of localized eczema in children with good tolerability.

Objective:To study the value of sound touch elastography (STE) linear combined with ultrasound score (US) in the diagnosis of chronic hepatitis B (CHB) liver fibrosis, and to investigate whether their combination can improve the diagnostic efficiency of subdividing the degree of CHB liver fibrosis. Furthermore, a comparison with STE linear combined with the serological model was performed to seek the optimal linear combination model.Methods:A total of 313 subjects were enrolled from September 2018 to December 2021 in Shenzhen Third People′s Hospital Affiliated to Guangdong Medical University, including 259 patients with CHB who had completed liver biopsy and 54 healthy volunteers. CHB patients were divided into liver fibrosis group (F1-F4 group) according to METAVIR classification standard, and healthy volunteers were used as the control group. All subjects underwent liver ultrasound examination, STE and blood biochemical indexes of liver function. The US was performed according to the liver ultrasound examination, and the liver stiffness measurement (LSM) was measured by STE, aspartate aminotransferase and platelet ratio index (APRI) was calculated by blood biochemical index. Fisher discriminant analysis was used to establish the linear combination (LC) diagnostic marker of US and LSM, and the linear combination (LC2) diagnostic marker of LSM and APRI, successively. Spearman rank correlation coefficient was used to analyze the correlations between US, LSM, APRI, LC2, LC and pathological results. The ROC curves of US, LSM, APRI, LC2 and LC for diagnosing CHB liver fibrosis were plotted, and the diagnostic efficiency of above diagnostic markers was evaluated according to the accuracy, sensitivity, specificity and area under the ROC curve (AUC).Results:The formula for the linear combination of US and LSM was LC=0.986 0×US+ 0.166 7×LSM, and LC was highly positively correlated with pathological findings ( rs=0.851, P<0.001), higher than US, LSM, LC2 and APRI ( rs=0.825, 0.775, 0.802, 0.586, all P<0.001). LC showed the best diagnostic efficiency. The AUCs for diagnosing ≥F1, ≥F2, ≥F3 liver fibrosis and =F4 cirrhosis were 0.945, 0.911, 0.954, 0.955, respectively, which superior to the AUCs of US (0.913, 0.879, 0.934 and 0.916, respectively), the AUCs of LSM (0.860, 0.871, 0.934 and 0.952, respectively) and the AUCs of LC2(0.899, 0.883, 0.941, 0.946, respectively). Compared with US, the AUC of LC diagnosis of ≥F1, ≥F2, ≥F3 liver fibrosis and =F4 cirrhosis increased by 3.2%, 3.2%, 2.0% and 3.9%, respectively, with all significant differences ( P<0.05). Compared with LSM, the AUC of LC increased by 8.5%, 4.0%, 2.0% and 0.3%, respectively, with significant difference ( P<0.05) except for stage =F4 cirrhosis.Compared with LC2, the AUC of LC increased by 4.6%, 2.8%, 1.3% and 0.9%, respectively, and there were significant differences in the diagnosis of ≥F1 and ≥F2 liver fibrosis ( P<0.05). Moreover, the overall efficiency of LC2 was not significantly improved than LSM, the difference was not significant ( P>0.05). Conclusions:US, LSM, LC2 and LC can be used to diagnose the degree of CHB liver fibrosis, but LC is better than US or LSM and LC2 alone, especially in the subdivision of mild liver fibrosis, which is a promising new diagnostic marker to subdivide the degree of CHB liver fibrosis.

Objective To evaluate the efficacy and safety of polyene phosphatidylcholine injection in the treatment of liver disease.Methods Pubmed,Embase,The Cochrane Library,ClinicalTrial.gov,CNKI,SinoMed,VIP,and WanFang Data were electronically searched to collect randomized controlled trials(RCTs)of polyene phosphatidylcholine injection in the treatment of liver disease from inception to December 31st,2022.Two researchers independently screened literature,extracted data and assessed the risk of bias of the included studies.The Meta-analysis was performed using Stata 17.0 software.Results A total of 10 RCTs were included,including 809 patients.Meta-analysis showed that the effective rate in the polyene phosphatidylcholine injection group was higher than that in the control group(RR=1.12,95％CI 1.04 to 1.20,P=0.003 8).Compared with the control group,polyene phosphatidylcholine injection could decrease ALT level(MD=-18.92 U/L,95％CI-27.75 to-10.09,P＜0.001),AST level(MD=-31.19 U/L,95％CI-46.27 to-16.11,P=0.000 1),TBiL level(MD=-7.31 μmol/L,95％CI-10.75 to-3.88,P＜0.001),and GGT levels(MD=-48.93 U/L,95％CI-54.64 to-43.21,P＜0.001).Only one study reported mild adverse events,and six studies reported no severe adverse events in patients.Conclusion Current evidence shows that polyene phosphatidylcholine injection in the treatment of alcoholic liver disease can increase the effective rate,improve the levels of liver function indicators(ALT,AST,TBiL,and GGT),and has less adverse events.Due to the limited number and quality of included studies,the above conclusions need to be verified by more high-quality studies.
