Objective To observe the clinical curative effect of drug combined with psychological treatment on patients with sleep disorders after stroke.Methods A total of 180 cases of eligible patients with sleep disorders were included and randomly di-vided into control group and treatment group.Control group were treated with conventional vascular drug(estazolam,2 mg,before sleep);treatment group increased anxiolytic and sedative hypnotic drugs(venlafaxine,dexzopiclone)compared to control group.Af-ter 14 days,sleep quality,NIHSS were compared both within the treatment group and between the two groups.Results The Bar-thel index,NIHSS and PSQI of two groups had significant differences,and those index of treatment group before and after treat-ment had significant differences too(P <0.05).Conclusion Combined conventional cerebrovascular drugs with Venlafaxine,dexzo-piclone as well as psychological treatment significantly improved sleep quality of patients with acute stroke.

Three-way laryngeal mask airway (tLMA) was used in 31 patients aged 4-68 yr, weighing 10- 79 kg undergoing tracheal foreign body removal under general anesthesia. Anesthesia was induced with propofol 3 mg/kg, vecuronium 0.12 mg/kg and remifentanil 0.4 μg/kg. tLMA was inserted. The patients were mechanically ventilated. Anesthesia was maintained with iv infusion of propofol 2 mg . Kg-1 ? H-1, vecuronium 0.08 mg·kg-1·h-1 and remifentanil 0.15 μg·kg-1 ·min-1 . Radial artery was cannulated for BP monitoring and blood sampling. The operation time was 6-34 min and mechanical ventilation time 19-45 min. There was no significant change in SP, DP, HR, VT, Ppeak and Ppeak CO, during operation as compared with the baseline values before anesthesia. SpO2 was significantly increased at T2-6. PCO2, PO2 and O2sat were obviously improved after tLMA was used. All the patients emerged bom anesthesia within 30 min after operation. No aspiration, obvious gastrointestinal inflation, and pharyngeal and laryngeal edema and injury occurred. Mild agitation occurred in a short time during the recovery period in one patient. No complication occurred.

BACKGROUND: Irradiation therapy in the cancer patients after surgery may have negative effects on implant fixation. OBJECTIVE: To observe the effects of 60Co irradiation and trace element zinc on fixation strengths of titanium implant. METHODS: Thirty-six adult male rabbits were involved. One piece of titanium implant was separately placed into the bilateral proximal tibial heads in rabbits to set up animal models of titanium implants. The animals were randomly divided into control group, zinc supplement group, 60Co irradiation group and 60Co irradiation and zinc supplement group. Zinc sulfate of 10 g/L was administered intramuscularly to animals in the zinc supplement group at the dose of 4 mg/kg once per day, and those in the control group were treated with saline at the same dose. The animals in the 60Co irradiation group received 60Co irradiation at the dose of 45 Gy and saline by intramuscular injection. Those in the 60Co irradiation and zinc supplement group received 60Co irradiation and zinc sulfate. The animals were killed at 1, 4 and 12 weeks after treatment. The fixation strengths were measured and compared among groups. RESULTS AND CONCLUSION: (1) Zinc supplement made the titanium implants have higher fixation strengths, and reach a high level at 4 weeks after surgery. (2) 60Co irradiation significantly inhibited the fixation strengths of the implants. After 60Co radiation, zinc supplement stil could promote fixation strengths of titanium implants. (3) It is indicated that amount of zinc supplement after irradiation therapy can al eviate the negative effects of irradiation on implant fixation.

OBJECTIVE:To establish the method for simultaneous determination of the content of berberine hydrochloride, baicalin and osthole in Jinchan zhiyang capsules. METHODS:HPLC method was adopted. The determination was performed in Hypersil BDS C18 column with mobile phase consisted of methanol-acetonitrile-0.1%phosphoric acid-three triethylamine(50∶30∶19∶1, V/V/V/V) at the flow rate of 1.0 mL/min. The detection wavelengths were set at 265 nm (berberine hydrochloride),280 nm (baicalin)and 322 nm(osthole). The column temperature was set at 30 ℃,and sample size was 10 μL. RESULTS:The linear range of berberine hydrochloride,baicalin and osthole were 80-800 ng(r＝0.999 8),60-600 ng(r＝0.999 9),60-600 ng(r＝0.999 6),respectively. RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The limits of quantitation were 80,60,60 ng,respectively,and the limits of detection were 24,20,20 ng,respectively. The recovery rates were 97.4%-98.3%(RSD＝0.33%,n＝6),98.4%-99.6%(RSD＝0.42%,n＝6)and 96.9%-99.0%(RSD＝0.92%,n＝6),respectively. RSDs of durability tests were all lower than 1.2%. CONCLUSIONS:The method is simple, accurate, precise, stable, reproducible and durable. It can be used for simultaneous determination of berberine hydrochloride,baicalin and osthole in Jinchan zhiyang capsules.

OBJECTIVE: To explore the genetic basis for four patients suspected for Marfan syndrome (MFS). METHODS: Four male patients with suspected MFS and their family members who were treated at West China Second Hospital of Sichuan University from September 12, 2019 to March 27, 2021 were selected as the study subjects. Peripheral venous blood samples were collected from the patients and their parents or other pedigree members for the extraction of genomic DNA. Whole exome sequencing was carried out, and candidate variants were validated by Sanger sequencing. The pathogenicity of the variants was determined based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). RESULTS: Genetic testing revealed that all four patients have harbored variants of the FBN1 gene, including c.430_433del (p.His144fs) deletional variant in exon 5, c.493C>T (p.Arg165*) nonsense variant in exon 6, c.5304_5306del (p.Asp1768del) deletional variant in exon 44 and c.5165C>G (p.Ser1722Cys) missense variant in exon 42. According to the ACMG guidelines, the c.430_433del and c.493C>T were classified as pathogenic variants (PVS1+PM2_Supporting+PP4; PVS1+PS1+PS2+PM2_Supporting+PP4). c.5304_5306del and c.5165C>G were classified as likely pathogenic variants (PS2+PM2_Supporting+PM4+PP4; PS2_Moderate+PS1+PM1+PM2_Supporting). CONCLUSION The c.430_433del and c.5304_5306del variants of the FBN1 gene identified in this study were unreported previously. Above results have enriched the variation spectrum of the FBN1 gene and provided a basis for genetic counseling and prenatal diagnosis of patients with MFS and acromicric dysplasia.
