Objective To develop an instrument to measure the quality of life (QOL) suitable for Chinese adult patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and evaluate it. Methods A list of 72 items potentially related to QOL of patients with OSAHS was constructed via discussion with OSAHS related people, as well as referring to some foreign QOL instruments. Twenty patients were asked to identify the most significant items. Then, frequency, importance and impact score, which is the product of frequency and importance, of the items were calculated. Those items with an impact score equal to or greater than 1.5 were retained in the instrument. Fifty-two OSAHS patients were divided into two groups based on their apnea-hypopnea index (AHI) (AHI

Objective To evaluate the efficacy and safety of 131I-metaiodobenzylguanidine (131 I-MIBG) in treatment of malignant pheochromocytoma/malignant paraganglioma (MPHEO/MPGL).Methods The clinical data of 96 cases of MPHEO/MPGL (60/36) treated with 131I-MIBG between December 1998 and April 2014 were retrospectively reviewed.Among them,the malignant pheochromocytoma was found in 60 cases and malignant paraganglioma was found in 36 cases.Seventy-eight patients (81.2％)presented initially with hypertension,whereas 18 patients (18.8％) presented adrenal incidentaloma.Before 131I-MIBG treatment,24 h urinary norepinephrine was (409.5± 127.2) nmol,24 h urinary dopamine was (99.3±41.1) nmol,24 h urine adrenaline was (1 409.9±336.0) nmol.Before treatment,the compound iodine solution was given to each one.Then,all patients were given an initial course of 131I-MIBG therapy (5.55,7.40 GBq).Subsequent 131I-MIBG treatment (5.55,7.40 GBq) was undertaken every three to six months.The patients got symptomatic,hormonal or radiological response underwent sbsequent 131I-MIBG therapy (3.70,5.55 GBq) every year.All patients underwent clinical symptoms (headache,palpitate,sweating,hypertension),biochemical (24 h urine catecholamin) and radiological evaluation (CT/MRI) within 6 months to evaluate the efficacy and safety of 131I-MIBG treatment.Results After one to eleven sessions of 131 I-MIBG treatment,in total,266 doses of 131 I-MIBG were administered,average dose was 6.49 GBq.22.9％ of patients demonstrated radiological partial response (≥ 50％ reduction in tumor size) after first or repeated 131 I-MIBG treatment.Eleven cases (11.5％) achieved clinical complete response,41 cases (42.7％) achieved clinical partial response and 23 cases (24.0％) maintained the stable clinic symptoms.After treatment,24 h urinary norepinephrine (164.3±71.6) nmol and dopamine (49.7±24.7) nmol showed significantly decline,compared with those before treatment (P＜ 0.05).While,24 h urinary epinephrine (1 354.7±433.4) nmol had no obvious change (P＞0.05).No life-threatening adverse events were reported,but 2 MPGL patients developed transient leucopenia or thrombocytopenia after four and five times 131 I-MIBG treatment,respectively.Conclusions Treatment with repeated low dose 131I-MIBG is well tolerated and effective in controlling the progression and alleviating the clinical symptoms.The 131I-MIBG therapy is an effective and safe treatment modality for MPHEO/MPGL.

Objective To investigate the effect of treatment for frozen shoulder by manipulation release combined with hydraulic pressure distension.Methods In this randomized trial,78 patients with frozen shoulder syndrome randomly divided into three groups were enrolled in the study.28 patients were treated by manipulation release under interscalene brachial plexus anesthesia.23 patients were treated by sodium hyaluronate injection into glenohumeral joint combined with manipulation release.27 patients were treated by hydraulic pressure distension combined with manipulation release.All patients were followed for six months.Effective rate evaluation combined with pain evaluation and functional evaluation were adopted for final evaluation.Results There were significant difference between pre-treatment and post-treatment in each group.Effective rate of hydraulic pressure distension combined with manipulation release was 92.6%,which was superior to manipulation release (78.6% ) and sodium hyahronate injection combined with manipulation release ( 82.6% ).There were no significant difference in functional evaluation of the three groups.Conclusion Hydraulic pressure distension combined with manipulation release under interscalene brachial plexus anesthesia is a successful treatment for idiopathic frozen shoulder.

Objective To evaluate systematically whether administration of hypertonic saline transfusion affects clinical outcomes with compared to standard fluid in the early stage of resuscitation for traumatic shock patients.Methods Seven English and Chinese routine biology and medicine databases were searched for randomized controlled trials (RCTs) published from January 2002 to August 2012,and established inclusion and exclusion criteria to evaluate these RCTs.The quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.1 and Jadad' s score scale.RevMan 5.0 statistical software was used for meta-analysis.Results After evaluated 211 related literatures,five RCTs met all the inclusion criteria and were enrolled for meta-analysis.The meta-a nalysis demonstrated that early hypertonic transfusion did not decrease short-term (first 48 hours after admission) mortality (RR =1.04,P =0.74); nor did it decrease later-term (7day to 3month after injury) mortality (RR =0.97,P =0.72).It also did not decrease the total volume of fluid and blood transfusion required during the first day (P =0.38).Similarly,it did not affect the incidents of infections (RR =1.04,P =0.70),the length of stay in ICU (P =0.2) and total length of stay in the hospital.Conclusions Compared to standard fluid,there was no advantage on mortality and hospital infection by using hypertonic supplement transfusion in the early stage of resuscitation for traumatic shock patients.Hypertonic transfusion did not have any significant effect on the volume of total fluid and blood transfusion required the first day,and no trend of reduction for the length of ICU and hospital stay.Further well-designed randomized controlled trials are needed to demonstrate the cost effectiveness of hypertonic transfusion to traumatic shock patients while in ICU.

Objective To investigate the clinical efficacy of our self-designed adjustable weight-bearing brace for AO type B tibial shaft fractures managed by interlocking intramedullary nail.Methods A total of 68 consecutive patients with AO type 42-B tibial shaft fracture who had been managed from April 2013 to March 2015 hy interlocking intramedul]ary nail were recruited into our study.They were randomized into 2 equal groups (n =34).Group A received conventional therapy after operation while group B received auxiliary mauagement with our self-designed adjustable weight-bearing brace after conventional postoperative therapy for one week.The 2 groups were compared at postoperative 1,3 and 6 months and at the final follow-up in terms of visual analogue scale (VAS),weight-bearing status of the affected limb,time for fracture union,Radiographic Union Score for Tibial Fractures (RUST) and Johner-Wruhs scale.Results Of this series,62 cases were followed up for 12 to 18 months (average,14.7 months),5 ones were lost to the follow-up and one withdrew.The mean VAS scores at 3-month and 6-month follow-ups for group B were 2.5 ± 0.8 and 0.9 ± 0.6 respectively,significantly lower than those for group A (3.0 ± 0.9 and 1.4 ± 0.8 respectively) (P ＜ 0.05).In group A at 1-month,3-month and 6-month follow-ups,the weight-bearing status was 44.1％ ± 17.5％,72.0％ ±17.4％ and 86.4％ ±12.5％ while the mean RUST scores were 5.4±1.4,8.7±1.1 and 10.3 ± 1.1,respectively.In group B at 1-month,3-month and 6-month follow-ups,the weight-bearing status was 53.8％ ± 11.0％,84.1％ ± 12.2％ and 94.4％ ± 10.6％ while the mean RUST scores were 6.5 ± 0.8,9.9 ± 0.9 and 11.3 ± 0.8,respectively.There were significant differences between the 2 groups in the above indexes (all P ＜ 0.05).Group B achieved clinical fracture union after an average of 3.3 ±0.7 months,significantly faster than group A (3.9 ± 1.0 months) (P ＜ 0.05).According to the Johner-Wruhs scoring,group A had 19 excellent cases and 12 good ones while group B had 27 excellent ones and 4 good ones,showing a significant difference between the 2 groups (P ＜ 0.05).Conclusions Early application of our self-designed adjustable weight-bearing brace for patients with AO type B tibial shaft fracture managed by interlocking intramedullary nail can reduce postoperative pain,accelerate callus growth,shorten bony healing time and achieve satisfactory functional recovery.

AIM:To investigate the relationship between the expression of adducin 3 (ADD3) and its splicing isoforms and colorectal cancer (CRC).METHODS:The expression of ADD3, ADD3-Ia and ADD3-Ib in 50 pair of CRC tissues , 20 pairs of colorectal polyp tissues , and 2 CRC cell lines SW480 and SW620 before and after oxaliplatin or fluoroura-cil intervention were detected by real-time PCR.The cell activity was determined by MTT assay , the cell migration ability was evaluated by wound-healing assay , and the cell invasion ability was measured by Transwell assay .RESULTS:The expres-sion levels of ADD3 and ADD3-Ib were decreased in the CRC tissues as compared with the normal mucous (P<0.01), and ADD3-Ia/Ib ratio was increased in the CRC tissues (P<0.01).The expression level of ADD3-Ia was higher in T3-4 group than that in T1-2 group (P<0.05).Reduced expression of ADD3, ADD3-Ia and ADD3-Ib in colorectal polyps was observed compared with the normal tissues (P<0.01).Compared with the SW480 cells, the expression levels of ADD3-Ia and ADD3-Ib were lower (P<0.05) and the ADD3-Ia/Ib ratio was higher (P <0.01) in the SW620 cells.After treated with oxalipla-tin or fluorouracil, the cell activity, migration and invasion in the SW620 and SW480 cells were weakened accompanied by the increases in the expression levels of ADD 3, ADD3-Ia and ADD3-Ib to various certain extents .CONCLUSION:In CRC there is a tendency that ADD3-Ib reduction leads to ADD3 decrease, accompanied by an increased ADD3-Ia/Ib ratio.The expression changes of ADD 3 and its splicing isoforms in the CRC may be relevant to its invasion ability .

BACKGROUND: Currently, the materials used in clinical practice to repair cruciate ligament of knee joint contain auto-graft bone- mid 1/3 patella tendon-bone (B-T-B), auto-semitendinous muscle, gracilis muscle and allogenic tissue graft. All of them are limited to a certain degree in clinical application. Therefore, people hope to consistently develop artificial ligaments to take the place of auto- and allografts. OBJECTIVE: To investigate the feasibility to construct artificial biological ligament (ABL) by applying a novel biochemical technique using porcine tendon as the raw material. DESIGN: Research of new biological material. SETTING: Department of Orthopedics, Third Affiliated Hospital of Sun Yat-sen University. MATERIALS: Adult pigs of either gender were provided by the Animal Center of Sun Yat-sen University. Scanning electron microscope (SEM, S-520) was provided by Hitachi, Japan, and micro-controlled electron tension-testing device (Model LWK-10B) by Guangzhou Experimental Devices Factory. METHODS: The experiment was performed at the Animal Center of Sun Yat-sen University from January 2004 to June 2005. ABL was established by means of treating porcine tendon with epoxy cross-linking fixation, diversified antigen minimization process, mechanic enhancement modification and surface activating process. Under aseptic condition, a 6-month-old goat's bone marrow was abstracted, and then the bone marrow matrix stem cells were cultured in ABL stent for 3 weeks. Scanning electron microscope was used to observe structure and compatibility of artificial ligament, and mechanics test was used to analyze biomechanics characteristics of ABL. MAIN OUTCOME MEASURES: Structural features, cell compatibility and biomechanics characteristics of ABL.RESULTS: ① Structural features of ABL: The appearance of ABL was similar to that of the normal human ligament. Histological examination showed that the ABL was collagen fibers with no cells. Electron microscope examination revealed that the ABL was composed of hair-looking and fiber-like objects running uniformly in a certain direction and closely parallel-arranged. ② Cell compatibility: Three weeks after xenogenic marrow matrix cells were cultured on the surface of the ABL, it was noted that cells adhered and the matrix secreted by the cells precipitated around the cells. There were no cells found inside the ABL. ③ Mechanical strength of the ligament: The average diameter of ABL was 5 mm and the mechanical test at a speed of 100 mm/min showed that its averaged tensile limit was 927.19 N and the tension-resistant strength was 47.22 N/mm those were close to the corresponding parameters of the normal goat's ACL. The normal goat's ACL was 5 mm. The greatest tensile load was 807.50 N and the tension-resistant strength was 41.13 N/mm.CONCLUSION:As we used the unique biochemical technique and minimized the xenogenic protein immunogenicity of the porcine tendon, ABL has acceptable biomechanical properties and superior biocompatibility. As a substitute of the ligament in the reconstruction of the ACL, ABL has a promising prospect in clinical applications.
