Objective To ascertain whether the growth inhibitor in conditioned medium from cultured rabbit arte rial cells is distinct from TGF-β. Methods Rabbit aortic smooth muscle ceils were grown from explained segments of the aorta. Conditioned medium from cultured rabbit aortic smooth muscle ceils and anti-TGF-β were employed in this study. Smooth muscle cell proliferation was measured by XTT detection (Boehringer Mannheim). Results Acidified conditioned medium from smooth muscle ceils had significantly stronger effects of growth inhibition than controls, and anti-TGF-β did not affect the growth inhibitory effect of conditioned medium from cultured rabbit arterial smooth muscle cells. Conclusion The growth inhibiting substance in conditioned medium from cultured rabbit aortic smooth muscle cells is distinct from TGF-β.

ObjectiveTo investigate an optimal treatment of localized low flow type venous malformation located in the oral and maxillofacial region.MethodsFifty seven patients with localized low-flow venous malformation were treated by intralesional injection of PYM.The injections was repeated at an interval of 10 to 14 days,but not more than 3-5 sessions within a therapeutic period.If necessary,the secondary therapeutic period was performed 1 month later.The general and local adverse responses and the appearance improvement were recorded.The clinical outcomes and aesthetic effects were assessed with a follow-up of 1 to 3 years.ResultsAfter 3-8 injections,complete clinical resolutions were achieved in 52 patients.The deformity disappeared thoroughly.The surface skin and the appearance of lesions showed normal.4 patients received completed lesion control and showed nor mal skin or muco but a little hypertrophy tissue.One venous malformation reduced 2/3 volume after 8injections but improved slowly.The therapeutic time seemed to be related with the size of lesion.Diameter less than 3 cm could be usually cured within 1 treatment period.No ulcerations or scars were presented in injection regions.The function of nerves in oral and maxillofacial region remained normality in all patients.The systematic complication included transient pyrexia and poor appetite appeared in several cases.No allergy was found.No clinical recurrence was observed during the follow-up.ConclusionsTreatment of localized low-flow venous malformations in oral and maxillofacial region with PYM sclerotherapy reveals a high rate of complete clinical resolution,a fair cosmetic and function result,and does not damage facial nerves or form local scars.And it might be regard as an optimal therapeutic method to localized low-flow venous malformations.

OBJECTIVETo investigate the effects of small interfering RNA (siRNA) targeting YAP on the proliferation and apoptosis of human periodontal ligament stem cells (hPDLSCs).

METHODSSynthesized sequences of siRNA were transfected into hPDLSCs by Lipofectamine™ 2000. The expression of YAP was identified by using real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Proliferation activity was detected by using cell counting kit-8 (CCK-8). Changes in the cell cycle and apoptosis rate were detected by using flow cytometry. Results were analyzed by using SPSS 19.0, and P < 0.05 was considered statistically significant.

RESULTSExpression of YAP mRNA and protein were significantly downregulated after 48 h of transfection (P < 0.001). No obvious difference was found in the expression levels of YAP protein between 48 and 72 h, thus indicating that siRNA could inhibit the expression of YAP persistently and effectively. Proliferation activity was inhibited, and apoptosis rate was increased. Cell cycle was changed as the proportion of G₁and S phases increased (P < 0.01) and G₂ phase decreased (P < 0.05).

CONCLUSIONKnocking down YAP gene by siRNA could inhibit proliferation activity, induce apoptosis, and change the cell cycle of hPDLSCs. Thus, YAP could regulate the proliferation and apoptosis of hPDLSCs.

Objective To investigate and analyze oral health status of inpatients with schizophrenia.Method We selected 105 patients from Beijing Anding hospital included hospitalization length 1-5 years group (39 cases) and hospitalization length over 5 years (55 cases) were investigated with Self-made questionnaire and assessment guide for psychiatric care (OAG-PC).Results Tooth loss and oral health status of schizophrenia inpatients were both poor.There was significant difference in the number of people with tooth loss (x2 =7.68,P ＜ 0.05) and mean number of tooth loss (F =9.20,P ＜ 0.05) between two groups.The OAG-PC total score (F=11.1,P＜ 0.05),odour from the mouth (F=4.34,P＜ 0.05),saliva (F=3.93,P＜ 0.05),mucous membranes (F=5.64,P＜ 0.05),teeth or dentures (F=5.34,P＜ 0.05),calculus on teeth (F=15.34,P ＜ 0.05),looseness of teeth (F =14.14,P ＜ 0.05),and No.of teeth in the lower jaw (F =7.70,P ＜ 0.05) in the schizophrenia inpatients with hospitalization length 1-5 years group was better than those with hospitalization length over 5 years,there were significant difference between two groups.There were no significant difference in lips (F =0.69,P ＞ 0.05),tongue (F =0.65,P ＞ 0.05),gums (F =1.87,P ＞ 0.05),appearance of teeth (F=1.52,P＞ 0.05),and No.of teeth in the upper jaw (F=3.58,P ＞ 0.05) between two groups.Conclusions Patients with schizophrenia are special vulnerable people.The more course of the disease was longer,the more the oral health status was worse.Tooth loss,calculus,and looseness of teeth are much more serious and will influence chew function seriously.Society,medical institutions,and families should pay more attention to the oral health status of patients with schizophrenia.And taking the preventative measures against poor oral health can improve quality of life of patients with schizophrenia.

OBJECTIVESTo provide the anatomical basis for surgical treatment of extraforaminal lumbar disc herniation (EFLDH) by paraspinous muscle splitting approach and to investigate the effect of its application.

METHODSThe relationship among the intertransverse processes, lateral margin of the pars interarticularis, anterior ramus of the lumbar nerve, and anterior ramus of the lumbar artery was studied in 34 cadaveric specimens. From October 1993 to October 1999, eleven cases of extraforaminal lumbar disc herniation were treated by paraspinous muscle splitting approach and retroperitoneal approach.

RESULTSIn the extraforaminal region, the anterior ramus of the lumbar artery and venus locate ventrally to the superior half of the intertransverse space, and the anterior ramus of the lumbar artery runs downward behind the nerve. The distance from the lateral margin of the pars interarticularis to the nerve root and the angle between the nerve root and midline sagittal plane were 1.0 - 2.0 cm and 7 degrees - 25 degrees respectively which increased gradually from L(1) to L(5). The period of follow up in 10 of 11 cases was 23 - 98 months. Evaluation according to Low Back Outcome Score showed excellent results in 8 cases, and good in 2.

CONCLUSIONSurgical treatment of EFLDH by paraspinous muscle splitting approach is safe, effective and minimal invasive.

Objective:To investigate the occurrence of deglutition disorders after extubation in neurosurgery patients, to explore the recovery time and influencing factors, and to provide reference for the development of nursing intervention plan for dysphagia after extubation.Methods:This was a prospective study. A total of 250 patients who underwent oral catheterization under general anesthesia in neurosurgery department and were admitted to the Tenth People′s Hospital of Tongji University from June to December 2022 were selected as the study objects by convenience sampling method. The general demographic and clinical data of the patients were collected to evaluate the occurrence of deglutition disorders after extubation. The outcome and recovery time of deglutition disorders were used as dependent variables. Kaplan-Meier method and Cox proportional hazard regression analysis were used to analyze the recovery time and influencing factors of deglutition disorders after extubation in neurosurgery patients.Results:The incidence of deglutition disorders after extubation was 35.6%(89/250) among 250 cases of neurosurgery patients under general anesthesia by endotracheal intubation, the recovery time of Deglutition Disorders after postoperative extubation was 1 - 16 (5.17 ± 0.43)days. ICU stay days, duration of endotracheal intubation and the first standardized swallowing assessment after extubation were the main influencing factors for the recovery of deglutition disorders in patients with dysphagia after extubation.Conclusions:For patients with deglutition disorders after extubation after neurosurgery, ICU stay days, duration of endotracheal intubation and the first standardized swallowing assessment after extubation affect the process of swallowing function recovery. Medical staff should focus on the risk groups and develop targeted nursing interventions to improve the outcome of patients.

A case of hemolytic disease of the newborn (HDFN) caused by immunoglobulin (Ig) G anti-E was analyzed in this study. The ABO and Rh blood group of the newborn was O and CcDEe, respectively. The ABO and Rh blood group of her mother was A and CCDee, respectively. Thus, the reason of ABO and RhD hemolysis were impossible. The incompatible antibodies were found in the newborn serum by three serological tests. The antibody screening and identification test using the plasma and the red blood cell eluate from the newborn and the plasma from her mother showed that the HDFN was caused by the IgG anti-E antibodies. The case was caused by failing to prenatal screening for irregular antibodies. Therefore, the prenatal screening for irregular antibodies seems necessary for pregnant women to prevent, diagnose or manage the HDFN at an early time, reducing the occurrence of perinatal complications.

OBJECTIVETo evaluate the safety and efficacy of exercise rehabilitation in coronary heart disease patients post reascularization procedure.

METHODWe searched the Cochrane Central Register of Controlled Trials (CCRCT), Pubmed, Wanfang, CNKI, CBM and VIP database for randomized controlled trials (RCTs) on exercise rehabilitation for patients with coronary artery disease post percutaneous coronary intervention revascularization or coronary artery bypass grafting. Quality assessment and data collection were conducted by two reviewers independently. The data were analyzed by Review Manager 5.0.

RESULTSA total of 3 474 patients from 16 RCTs were included in this meta-analysis and patients were divided into exercise rehabilitation group (n = 1 425) and control group (n = 2 049). Meta-analysis results showed mortality rate was similar between the two groups (OR = 0.81, 95%CI 0.38-1.69, P > 0.05) and the incidence of major cardiovascular events rate (OR = 0.40, 95%CI 0.24-0.65, P < 0.01) and heart rate [mean difference (MD) = -2.82, 95%CI -4.72--0.92, P < 0.01] were significantly lower while LVEF (MD = 2.24, 95%CI 0.18-4.31, P < 0.05), the exercise metabolic equivalent (MD = 0.94, 95%CI 0.43-1.44, P < 0.01) , anaerobic threshold (MD = 1.83, 95%CI 0.67-3.00, P < 0.01) , and maximum oxygen consumption (MD = 3.22, 95%CI 2.42-4.03, P < 0.01) were significantly higher in exercise rehabilitation group than in control group.

CONCLUSIONExercise rehabilitation does not increase the risk of mortality in patients of coronary heart disease after revascularization and can effectively reduce major cardiovascular events.

ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4^th and 7^th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7^th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7^th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7^th day compared with those on the 4^th day of treatment （P<0.05）. On the 4^th and 7^th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.
