OBJECTIVETo evaluate the clinical outcomes of percutaneous intervertebral foramina endoscopic lumbar discectomy for elder patients with lumbar spinal stenosis syndrome.

METHODSFrom July 2006 to July 2011, 60 elder patients with lumbar spinal stenosis syndrome were treated with surgical operation, including 32 males and 28 females with an average age of (66.7 +/- 2.5) years old ranging from 72 to 83 years. These patients were divided into the traditional surgery group and percutaneous intervertebral foramina endoscopic discectomy groups (PTED group), 30 cases in each group. The index of the preoperative and postoperative, operative incision visual analogue scale (VAS) of two groups were compared. The Oswestry disability index (ODI) of two groups at 6, 24 months of the follow-up were also evaluated on activity of daily living.

RESULTSThe average operative time, the average blood loss, the number of cases using analgesic drug, hospitalization time of PTED group were better than those of the traditional surgery group (P < 0.05). The improvement of incision VAS in PTED group was better than that in the traditional surgery group (P < 0.05). All patients were followed up for 24 months at least. The ODI at 1, 24 month after operation were better than that of preoperative in two group respectively (P < 0.05), but the improvement of PTED group was better than that of the traditional surgery group (P < 0.05).

CONCLUSIONPTED has the advantages of smaller incision, less bleeding, less postoperative stay and hospitalization time, tissue trauma and quicker recovery. It is a safe and efficacious minimally invasive surgical technique for elder patients with lumbar spinal stenosis syndrome.

Objective To study the curative effect and the prognostic factors of endoscopic traumatic optic neuropathy (TON). Methods The clinical data of 53 patients with TON from 2010 to 2015 years was retrospectively analyzed. Divided the patients into the surgery group and the non-surgery group, according to whether or not accept the treatment of endoscopic optic decompression. And evaluating the potential prognostic factors in chi-square test, group t-test and multiple regression analysis. Results In 53 patients (55 eyes ), 31 eyes have no visual acuity before treated: 8 eyes’ visual acuity was improved in 16 eyes (8/16) that accepted operation; 3 eyes’ visual acuity was improved in 15 eyes (3/15) that with non-operation;24 eyes have visual acuity before treated:11 eyes’ visual acuity was improved in 14 eyes (11/14) that accepted operation;3 eyes’ visual acuity was improved in 10 eyes (3/10) that with non-operation;19 eyes’ visual acuity was improved in 30 eyes (19/30) that accepted operation, the total effective rate was 63.3%, and there was no complications happened in the patients who accepted operation. The age, eye-side, sex, visual acuity, optic canal fracture , orbit fracture , all these factors have no correlation to the prognosis (P>0.05), but the interval time between injury and operation (less than 3 days) and the way of the treatment are benefit to improve vision (P<0.05). Conclusions The endoscopic optic decompression is an effective treatment in TON, and it’s better to improve vision in 3-day after TON.

A chiral LC-MS/MS method for the simultaneous analysis of desvenlafaxine (DVS) enantiomers in human plasma was developed and applied to a pharmacokinetic study on 12 Chinese healthy volunteers. d6-Desvenlafaxine was used as internal standard (IS). Chromatographic separation was performed on the Astec Chirobiotic V chiral column (150 mm x 4.6 mm, 5 μm). The assay was linear over the concentration range of 0.500-150 ng x mL(-1) for both enantiomers (r2 > 0.99). The method was successfully applied to a stereoselective pharmacokinetic study of 100 mg desvenlafaxine sustained release tablets on 12 Chinese healthy volunteers under fasting conditions. The results showed that the pharmacokinetic parameters were similar to both enantiomers in Chinese healthy volunteers. The AUC(0-t), and C(max) of the two enantiomers were about 1.5 times higher than those of blacks and whites reported in the literature.

Objective To investigate the efficacy of emergency vacuum sealing drainage (VSD) in the treatment of crush syndrome. Methods A total of 102 patients with crush injury were randomly screened out and divided into emergency VSD group (n = 50), delayed VSD group (n = 22) and control group (n = 30). The variances of indices of crush syndrome after VSD between three groups were analyzed. Results The vital sign, urine volume, laboratory examination results were improved and the incidence rate of crush syndrome, complications and mortality rate were significantly decreased in emergency VSD group than those in delayed VSD group and control group (P < 0.05). For patients with crush syndrome, the incidence of complications, duration of hospital stay and mortality rate were significantly decreased in emergency VSD group and delayed VSD group than those in control group (P < 0.05). Conclusion Emergency VSD can suck the exudate of the necrotic tissues and the wounds, maintain draining wounds and prevent infection and hence is helpful to prevent and treat the crush syndrome.

Objective To evaluate the application value of bedside lung ultrasound in diagnosis of neonatal severe pneumonia.Methods Bedside lung ultrasound and chest X-ray were performed in 59 the newborn patients admitted to the newborn department for suspected severe pneumonia,from October 2015 to March 2016.According to the characteristics of the chest X-ray,patients were divided into consolidation group (widely spot shadow in double lung and airbronchograms) and the unconsolidation group (enlargement,fuzzy texture in double lung or small patch sample changes) Differences in ultrasonic characteristics were compared between the two groups.Results Ultrasonic image characteristics were pulmonary consolidation with air bronchograms,A-line disappearance,pleural line abnormalities.Among 23 patients with chest X-ray,21 patients were found pulmonary consolidation by lung ultrasound,and all 36 patients in unconsolidation group were not found pulmonary consolidation by lung ultrasound,and there was no significant difference in the detection rate by lung ultrasound between the two groups (P＞0.05) The pulmonary ultrasound results of 20 cases in the consolidation group showed A-line disappearance,37 cases in the unconsolidation group showed A-line disappearance.There was no statistical significant differences between the two groups (P＞0.05).The pulmonary ultrasound results showed 11 cases in the consolidation group and 15 cases in the unconsolidation group with pleural line abnormalities,there was no statistically significant differences between the two groups (P＞O.05).Conclusions Ultrasound image characteristics of neonatal severe pneumonia include pulmonary consolidation and air bronchograms,A-line disappearance,pleural line abnormalities.Compared lung ultrasound and chest X-ray result,there was no difference between consolidation group and unconsolidation group.Both of the two methods can be used for evaluating the diagnosis of pneumonia.

Objective: To explore the relationship between serum vitamin D level and coronary artery lesion severity and short-term prognosis in coronary artery disease (CAD) patients. Methods: A total of 323 CAD patients diagnosed according to coronary angiogram were selected and the coronary artery lesion severity was evaluated by using Gensini score. Clinical data was collected and serum level of vitamin D and other indicators were determined for statistical analysis. Results: All patients were divided into tertile according to Gensini score. The level of serum vitamin D concentration was significantly different from the lowest tertile to the highest tertile (P=0.000). Serum vitamin D level was negatively correlated with Gensini score in CAD patients (r=-0.182, P=0.001). Multivariate linear analysis showed that vitamin D level was an independent predictor of Gensini score (β=-0.795, P=0.000). There was no difference in the incidence of major advanced cardiovascular events between vitamin D deficiency patients and normal vitamin D level patients (2.05% vs 3.17%, P=0.202) after (18.14±3.04) months' follow-up. Conclusion: There is an independently negative correlation between serum vitamin D and coronary artery lesion severity in CAD patients.
