Objective In patients with pulmonary atresia and intact ventricular septum ( PAIVS) without right ventricular-dependent coronaries, catheter techniques including the use of a sniff wire, lasers, and radiofrequency have been the most widely used initial therapy. However, percutaneous perforation and balloon valvuloplasty were associated with higher rate of procedural failure and serious complications. Methods We report our experience with a hybrid approach for pulmonary atresia with intact ventricular septum, combining surgery and interventional catheterization techniques. Between March 2005 and March 2010, hybrid procedure was carried out successfully in 30 newboms and infants with favorable anatomy. The age ranged from 1 day to 48 months with a mean of (4.59 ±3.21) months. The heart was exposed through median sternotomy. A pursestring suture was placed in the right ventricular outflow tract 2 cm away from the pulmonary trunk. Then a 16-gauge intravenous catheter was punctured through the right ventrical and perforated the atretic PV with the guidance of echocardiography. A guide wire was then inserted into the sheath and used to guide the balloon across the PV. Sequential dilations were performed until a full opening of the PV with the guidance of epicardial echocardiography. In patients < 3 months PDA ligation was performed followed by modified Blalock-Taussig (B-T) shunt. In patients > 3 months PDA ligation was not performed. A modified B-T shunt was inserted if severe systemic oxygen desaturation occurred after PDA ligation. Bidirectional Glenn shunt was performed for severe hypoplasia. Hybrid procedure was achieved in all patients. The simultaneous procedures included 25 cases of PDA ligation. 6 newborns underwent modified B-T shunt placement (3.5 to 5 mm) after pulmonary valvuloplasty and PDA ligation, and 2 patients > 1 month underwent modified B-T shunt. Another 2 patients were selected for univentricular palliative surgery because of a diminutive monopartite right ventricle and bidirectional Glenn procedure was performed. No pericardial effusion or cardiac tamponade was observed in all patients. Another case without PDA ligation underwent a modified B-T shunt because of hypoxemia three days after hybrid procedure, and the rest patients were discharged without any further surgical intervention.During the follow-up period of 1.5 to 62.0 months, 5 patients died. 25 (83.3%) survived and were all in New York Heart Association functional class 1. Peripheral oxygen saturation increased from 0.73 ± 0.08 to 0.94 ± 0.04 (P < 0.05). One patient remains in a single-ventricle pathway, whereas 24 patients achieved a two-ventricle circulation. Results Conclusion Perventricular balloon pulmonary valvuloplasty using a hybrid approach is a safe and feasible procedure for patients with PAIVS.

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.

OBJECTIVETo assess the methodological quality of systematic reviews or Meta-analysis of traditional Chinese medicine published in China, and to validate the applicability of OQAQ (Overview Quality Assessment Questionnaire) and AMSTAR (a measurement tool to assess systematic reviews) in traditional Chinese medicine (Chinese Medical).
METHODSComprehensive literature retrieve was performed in CBM, CNKI, VIP as well as hand searching in Chinese Journal of Evidence-Based Medicine. The retrieve was started from January 1, 1999 and terminated by December 2008. The methodological quality of traditional Chinese medicine correlated systematic reviews was evaluated using OQAQ and AMSTAR simultaneously.
RESULTSA total of 115 systematic reviews involved 17 types of diseases, of which, the cardio-/cerebrovascular diseases was dominant (36 papers, 31.30%). The mean OQAQ score was 2.50 (95% CI: 2.22, 2.76). No significant correlation was found in OQAQ score with publication year (P = 0.35) and different disease types (P = 0.28). High consistency was observed in evaluations of systematic reviews by using OQAQ and AMSTAR (both Kappa values > 0.75). Compared with the OQAQ, AMSTAR incorporated 3 additional items: the topics, publication bias, and conflict of interest, etc. Although 98.26% of systematic reviews proposed protocols in prior, 53.04% failed to analyze the publication bias. Besides, 57.39% neglected to address the potential conflict of interest.
CONCLUSIONSPoor methodological quality in systematic reviews of Chinese Medical published in China needs to be improved and emphasized. It is necessary to integrate the special characteristics of traditional Chinese medicine itself when choosing topics of systematic reviews. It is essential to establish quality assessment tools targeting systematic reviews of traditional Chinese medicine.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.
METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.
RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.
CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

OBJECTIVETo discuss the mechanism of scar hypertrophy in adenosine receptor A(2A) (A(2A) R) knockout mice.
METHODSAnimal models of hypertrophic scar were established in 12 A(2A) R knockout mice and 12 wild-type mice as control. The thickness and the size of transverse section of the hypertrophic scar were observed by H-E staining. The hydroxyproline (HYP) in the scar was measured colorimetrically. The TGF-beta expression was tested by Western blotting method.
RESULTSThe hypertrophic scar in wild-type mice was more severe than that in knockout mice. Compared with self-control, the increase of the thickness and the size of transverse section of hypertrophic scar was markedly higher in wild-type group than in the knockout group (P < 0.01). There was significant difference in HYP content between the two groups (P < 0.01). Compared with self-control, the increase of TGF-beta expression in wild-type group was much more than that in knockout group (P < 0.01).
CONCLUSIONSThe TGF-beta expression decreases in the A(2A) R knockout mice. The scar hypertrophy is also much less in the A(2A) R knockout mice.

OBJECTIVETo investigate the prevalence and potential risk factors of dentine hypersensitivity of adults in rural of Sichuan province.
METHODSAll representative samples, including 630 adults living in rural of Sichuan Province, were selected by multi-stage, stratified and random sampling. The dentine hypersensitivity of all 630 cases was surveyed with questionnaire and oral clinical examination. SPSS 18.0 software was used for statistical analysis.
RESULTS27.9% of all subjects were suffered from dentine hypersensitivity, sour was the most common stimulus of dentine hypersensitivity. The first premolar was the most common tooth with dentine hypersensitive, which occupied 27.4% of the total affected teeth. Female, acid regurgitation symptom, low frequency of toothbrush replacement (over 3 months), high tooth-brushing force and frequency of fresh fruits consumption (over 2 times per week) probably were high risk factors of dentine hypersensitivity.
CONCLUSIONThe prevalence of dentine hypersensitivity occurs in rural of Sichuan province is high, thus for future the publicity and education on dentine hypersensitivity preventive should be strengthened.

OBJECTIVETo investigate the clinical characteristics and risk factors of dentine hypersensitivity in smaller cities and rural area in Sichuan province.
METHODSThe examinee aged 20 - 69 years old were interviewed and divided into five age groups (20 - 29, 30 - 39, 40 - 49, 50 - 59 and 60 - 69). The random sampling methods were performed in this study. A total of eight spots were survied, including 4 communities and 4 spots in rural area of Sichuan province. The information about the examinee's age, gender, occupation, education level, tooth brushing methods, the frequencies of eating fresh fruits and fruit juices and so on, were asked and recorded. All subjects were further diagnosed by a blast of air from a triple syringe connected to an air compressor at a pressure of 4 atm under room temperature of about 19 - 24°C.
RESULTSThe premolars were the most commonly affected, followed by the first molar. The exposed root surface was the most commonly affected position [63.87% (663/1038)]. The first premolar had the greatest number of teeth with dentine hypersensitivity [29.96% (311/1038)]. Different tooth had different sensitive position. Female, too much time of using a tooth brush, and hydrochloric acid in gastric juice were risk factors for dentine hypersensitivity (OR value = 2.175, 1.157, 1.760).
CONCLUSIONSDentine hypersensitivity is influenced by multiple factors. Prevention and treatment need be performed by improving general oral health and periodontal conditions.

OBJECTIVETo investigate the self-assessment characteristics of Voice Handicap Index (VHI) for voice disorders and its influencing factors.
METHODSOne thousand seven hundred and sixty six dysphonic patients and 120 control subjects were included in this study. Two hundred twenty seven patients were treated with phonosurgery or Botulinumtoxin injection. VHI was used for self-assessment.
RESULTSDysphonic patients had worse VHI scores than control (z from 8.039 to 17.043, P = 0.000). There was a significant difference among the VHI scores of different diseases. VHI scores were descending in order among spasmodic dysphonia, vocal fold paralysis, functional dysphonia, sulcus vocalis, benign and malignant tumor of vocal fold, vocal fold cyst, Reinke's edema, vocal fold polyp, vocal fold keratosis and chronic laryngitis, vocal nodule. The emotional scores were the highest in spasmodic dysphonia, and followed by functional dysphonia. In another group, the physical scores were higher than functional scores and emotional scores. Treatment resulted in statistical improvement in VHI scores (P < 0.05). The total scores were different significantly between different educational background and age groups (F from 8.701 to 27.371, P = 0.000). The higher the educational degree, the higher the VHI scores. As to age groups, the juvenile group's scores were the lowest, while the youth's group the highest, then the scores declined when ages increased.
CONCLUSIONAs a useful supplementary instrument to measure the voice disorder severity and the treatment's effect, VHI can comprehensively assess the voice handicap's affect to the life quality and the difference after the treatment, especially in physical, functional and emotional aspects, but it is somehow subject to the educational degree and age.
