OBJECTIVETo analyze the reasons why anterior decompression and titanium mesh fusion for cervical spondylosis always show poor therapeutic effects, and to investigate the clinical effects of anterior revision surgery in these patients.

METHODSFrom January 2004 to December 2011, 16 patients underwent anterior decompression and titanium mesh fusion for cervical myelopathy were treated with anterior revision surgery. There were 7 males and 9 females with an average age of 61 years old (ranged from 46 to 75 years), including 11 cases with cervical spondylotic myelopathy, 2 cases with nerve root cervical spondylosis and 3 cases with mixed type cervical spondylosis. Average duration from the first operation to reoperation was 7 years(ranged from 4 to 12 years). In the first operation, titanium mesh segment located in C3-C5 (2 cases), C4-C6 (8 cases), C4-C7 (2 cases), C5-C7 (4 cases), and one of them, titanium mesh implantation in C4 and C5,6 intervertebral disk removal and cage fusion. After the first operation, symptom of 13 patients recurred after improvement or disappearance, 2 patients did not show obvious improvement, and 1 patient aggravated. Cervical spine radiography, CT scan and MRI were performed in all patients before re-operation. There were 12 patients with compression of the spinal cord or nerve root caused by degenerative changes in adjacent segments of fusion segments, 4 cases in upper segments, and 8 cases in lower segments; 3 patients with compression of the spinal cord or nerve root caused by vertebral posterior osteophyte of decompressed segments; 1 patient with compression of the spinal cord caused by incomplete anterior decompression. JOA, NDI and Odom classification were used to assess the clinical effects.

RESULTSAll anterior revision surgery were successful with a mean time of 110 min (80 to 150 min) and mean bleeding of 160 ml (30 to 200 ml). There was 30 ml clear drainage fluid in 1 patient suspected of cerebrospinal fluid leakage. But the 2nd day after operation, the tube was removed and the drainage opening was sutured, and the suture incision healed in grade A after 10 days. Other patients had no complications such as dysdipsia, hoarseness, and laryngeal edema, etc. All patients were followed up for 12 to 28 months with an average of 16 months. Two months after operation and at last follow-up, JOA scores and ODI index had obviously improved than preoperation (P < 0.01), and there was significant difference between postoperative 2 months and last follow-up (P < 0.01). At the final follow-up, improvement rate of JOA was (72.9 +/- 0.2)%. According to the standard of Odom, 12 cases got excellent results, 3 good, 1 fair.

CONCLUSIONAfter surgery of cervical decompression and bone graft fusion with titanium mesh, the patients need re-operation because of incomplete decompression, degenerative changes in adjacent segments or newly formed compression factors, and complications caused by implants. Anterior revision surgery can obtain good clinical effects.

OBJECTIVETo explore the efficacy of tumor-ablative individualized allogeneic hematopoietic stem cell transplantation for the treatment of patients with high risk/refractory leukemia.

METHODSFivety-seven patients with high risk/refractory leukemia were enrolled. Tumor-ablative individualized conditioning regimens included HDAra-C + Bu/Cy, Ara-C + Bu/Fludarabine, G-CSF primed HDAra-C + Bu/Cy, and FLAG followed by reduced-intensified BuCy. Overall survival (OS), disease free survival (DFS), graft versus host disease, infection and relapse post grafting were analyzed.

RESULTSFifty-six patients attained durable engraftment. The median follow-up duration was 17.5 (2 - 34) months. The 18 months probabilities of OS and DFS were (74.7 ± 6.1)% and (62.4 ± 6.7)%, respectively. In addition, the 18 months probabilities of OS and DFS in patients who attained complete remission (CR) before transplantation were (74.2 ± 7.1)% and (58.8 ± 8.1)%, respectively, while in those not attained CR were (77.0 ± 11.8)% and (72.7 ± 11.7)%, respectively. Twenty nine patients developed acute GVHD (aGVHD) (grade I in 18, grade II in 4, grade III in 2 and grade IV in 5). The probabilities of aGVHD was (50.9 ± 6.6)% by Kaplan-Meier curve analysis. The probabilities of grades 2-4 and grades 3-4 aGVHD were (19.3 ± 5.2)% and (12.3 ± 4.3)% respectively. Extensive chronic GVHD (cGVHD) was observed in 36 patients. The probabilities of cGVHD was (64.3 ± 6.4)% by Kaplan-Meier curve analysis. Cytomegaloviremia (CMV) was observed in 39 (68.42%) patients, hemorrhagic cystitis in 13 (22.8%) patients, fungous infection in 16 (28.07%) patients and bacterial infection in 38 (66.67%) patients. Relapse occurred in 14 patients (hematologic relapse in 11 and extramedullary relapse in 3), probabilities of relapse being (24.6 ± 5.7)%. The 17.5-month probability of relapse in patients who attained CR before transplantation was (28.1 ± 7.7)%, while in those not attained CR was (15.6 ± 10.2)%. Fifteen patients died (6 from hematological relapse, 5 from infection of bacterial and fungous, 4 from cGVHD) after 100 days.

CONCLUSIONTumor-ablative individualized allogeneic hematopoietic stem cell transplantation is a promising and safe choice for treatment of high risk/refractory leukemia, even with high leukemia burden.

OBJECTIVETo investigate the ultrasonographic features of obstructive azoospermia and to evaluate transrectal ultrasonography in the diagnosis of the disease.

METHODSWe performed transrectal ultrasonography for 248 patients with obstructive azoospermia, observed the sonographic features of the prostate gland, seminal vesicle and ejaculatory duct.

RESULTSThe average volume of the prostate gland of the studied group was 13.2 ml. A total of 111 cases showed normal sonographic features, 39 cases bilateral seminal vesicle defect, 33 cases bilateral seminal vesicle aplasia, 23 cases unilateral seminal vesicle defect and contralateral seminal vesicle aplasia, 28 cases bilateral and 14 cases unilateral seminal vesicle dilatation. Of the 42 cases of seminal vesicle dilatation, 18 had ejaculatory duct dilatation and 17 had cysts in the midline of the prostate.

CONCLUSIONObstructive azoospermia varies in kind. Transrectal ultrasonography can reveal the details of the prostate, seminal vesicle and ejaculatory duct and help to classify obstructive azoospermia and determine the location of the lesion.

D-myo-inositol 1,4,5-trisphosphate (IP(3)) plays an important role in signal transduction. It releases Ca(2+) from intracellular sites, which activates the Ca(2+)-dependent channels such as large-conductance Ca(2+)-activated potassium channels (BK channels). The present study was therefore designed to determine if the activity of BK channels in porcine coronary artery smooth muscle cells was increased by IP(3). Using the inside-out patch-clamp technique, the activity of single BK channels was recorded in porcine coronary artery smooth muscle cells. In excised inside-out membrane patches, IP(3) (10-50 micromol/L) enhanced the open probability (Po) of BK channels in a dose-dependent manner in the intracellular side of inside-out patches and its effect was almost completely abolished by washout. The open-state probability of the BK channels increased from a control level of 0.0402+/-0.0152 to 0.1365+/-0.0212 (20 micromol/L IP(3)) and 0.1865+/-0.0175 (30 micromol/L IP(3)). IP(3) decreased the mean close time markedly, but had no effect on the amplitude of BK channels. The activation of IP(3) on BK channels did not decline. The metabolite of IP(3) had no obvious effect on BK channels. This study provides evidence that IP(3) activates BK channels in porcine coronary artery smooth muscle cells in a dose-dependence manner.

To approach the method of isolation of tolerant human atrial myocytes, single myocytes were isolated by modified procedure of enzymatic dissociation with protease (type XXIV) and collagenase (type V). L-type calcium channel current (I(Ca-L)), sodium current (I(Na)), transient outward potassium current (I(to1)), and inward rectifier potassium current (I(K1)) in isolated atrial myocytes were recorded by using whole-cell patch-clamp techniques. Single cardiocytes isolated by this method were smooth, well-striated and rod-shaped. The yields of recordable myocytes, which viable and calcium-tolerant for electrophysiological studies, were 50%-60% of the total isolated cells. Compared with other isolation methods, this method was simple and steady, but with yield of a great number of qualified myocytes. The currents recorded in these cells were functional and active. Our research suggests that the myocytes isolated by the described method in this paper have normal electrophysiological function and are appropriate for patch-clamp experiments.

OBJECTIVETo explore the associated risk factors of metabolic syndrome in Jiangsu province, China.

METHODSUsing identical protocol and questionnaire, an epidemiological study was carried out in a population of 5888 adults in 12 counties in Jiangsu. Anthropometric test and blood sampling were conducted at the time of interview. IDF (2005) was used as the diagnostic criteria of metabolic syndrome . The prevalence and age-standardized prevalence of metabolic syndrome were calculated. Univariate and multivariate logistic regression model were used to identify associated risk factors.

RESULTSThe prevalence and age-standardized prevalence of metabolic syndrome in Jiangsu were 19.07% (11.10% in males and 25.72% in females) and 17.48% (11.49% in males, 22.86 % in females), respectively. Among the potential risk factors of metabolic syndrome as gender, age, education level, occupation, income, physical activity, smoking, alcohol drinking, disease family history, data from univariate and multivariate logistic regression analyses suggested that gender (OR = 1.91), age (OR = 1.15), physical inactivity (OR = 1.94), with hypertension family history (OR = 1.99) and with obesity family history (OR = 6.24) could significantly increase the risk of disease development.

CONCLUSIONMetabolic syndrome has become a significant public health problem among the adults in Jiangsu province.

Continued smoking following stroke is associated with adverse outcomes including increased risk of mortality and secondary stroke.The aim of this study was to examine the long-term trends in smoking behaviors and factors associated with smoking relapse among men who survived their first-ever stroke.Data collection for this longitudinal study was conducted at baseline through face-to-face interviews and follow-up was completed every 3 months via telephone,beginning in 2010 and continuing through 2014.Cox proportional hazard regression models were used to identify predictors of smoking relapse behavior.At baseline,372 male patients were recruited into the study.Totally,155 (41.7％) of these patients stopped smoking for stroke,and 61 (39.3％) began smoking again within 57 months after discharge with an increasing trend in the number of cigarettes smoked per day.Exposure to environmental tobacco smoke at places outside of home and work (such as bars,restaurants) (HR,2.34;95％ CI,1.04-5.29,P=0.04),not having a spouse (HR,0.12;95％ CI,0.04-0.36;P=0.0002) and smoking at least 20 cigarettes per day before stroke (HR,2.42;95％ CI,1.14-5.14,P=0.02) were predictors of smoking relapse.It was concluded that environmental tobacco smoke is an important determinant of smoking relapse among men who survive their first stroke.Environmental tobacco smoke should be addressed by smoke-free policies in public places.

OBJECTIVETo evaluate the clinical outcome of percutaneous endoscopic lumbar discectomy with target foraminoplasty in treating migrated lumbar disc herniation.

METHODSFrom June 2015 to January 2016, 25 patients with migrated lumbar disc herniation were treated with percutaneous endoscopic lumbar discectomy with target foraminoplasty. A total of 14 males and 11 females, aging from 23 to 52 years old (average: 37.6) were enrolled in this study. Discectomy occurred in L₂,₃ of 1 case, L₃,₄ of 3 cases, L₄,₅ of 12 cases, L₅S₁ of 9 cases. Preoperative, 1-week and 1-year postoperative visual analogue scale (VAS) scores were collected to evaluate lower back and leg pain; Oswestry Disability Index(ODI) was used to assess the lumbar function.

RESULTSAll the patients were followed up for 12 to 19 months with an average of 15.2 months. The mean operation time was 108.6 min. No injury of dura, nerve root, or wound infection were found. Preoperative, 1-week and 1-year postoperative visual analogue scale(VAS) scores of lower back pain were 5.8±0.5, 2.5±0.4, 0.9±0.2, respectively, with significant differences among each other(<0.05);VAS scores of leg pain were 7.1±0.6, 1.5±0.4, 0.7±0.6, respectively, with significant differences among each other(<0.05). Lumbar ODI scores were 69.2±1.8, 22.5±4.7, 10.2±2.4 at the above time points and showed significant differences among each other(<0.05).

CONCLUSIONSPercutaneous endoscopic lumbar discectomy with target foraminoplasty for migrated lumbar disc herniation showed advantages of less injuries, bleeding and complication. It also promotes rapid recovery, being curative safely and effectively.

Objective To assess the academic level of randomized controlled trial abstracts in papers on budesonid adjuvant therapy for children pneumonia and analyze its influencing factors. Methods The randomized controlled tri-al abstracts in papers on budesonid adjuvant therapy for children pneumonia were assessed according to the CON-SORT 2010 Statement and were statistically analyzed using the RevMan 5 . 3 . Results The items with a low reporting rate of the randomized controlled trial abstracts in the 282 papers included in this paper were "title judged as ran-dom","communication author","randomized","blind method","randomized grouping cases","fund-suppor-ted". Hierarchical analysis showed that the number of words in abstracts played an important role in affecting the reported items. Conclusion The academic level of randomized controlled trial abstracts in papers on budesonid adju-vant therapy for children pneumonia is significantly different from that of the abstracts in clinical papers according to the CONSORT 2010 Statement. Researchers should thus use the CONSORT 2010 Statement-defined items in writing their papers in order to improve the academic level and readability of their abstracts.
