Objective To measure the concentration of electrolytes such as potassium,sodium,chloride,calcium in EPS and urine of patients with chronic prostatitis and to analyze the correlation of the electrolytes in different patient groups. Methods The concentrations of potassium,sodium,chloride and calcium in EPS and urine of 31 controls and 79 patients with prostatitis were measured and analyzed. Results There was no significant difference between the patients and normal controls in electrolytical concentration of potassium,sodium,calcium except chloride (P=0.001).The concentration of chloride in the patients was significantly higher than that in the normal controls.In the treatment effective group, potassium concentrations were decreased from 40.66?17.10 to 33.42?17.27 mmol/L after treatment.In the treatment ineffective group, potassium concentrations were (37.57?16.93)mmol/L before treatment and 50.66?18.77 mmol/L after treatment.Potassium concentrations were 36.02?12.36 and 48.90?16.93 mmol/L in the pain group and painless group,respectively.There were positive correlations between the concentrations of potassium and calcium of EPS,sodium and chloride of urine as well. Conclusions The concentrations of potassium in EPS are obviously different between the effective group and ineffective group or the pain group and painless group.There is a close relationship between the concentration of potassium and calcium of EPS,sodium and chloride of urine; and they are positively correlated.

Objective To evaluate the value of video-assisted thoracic surgery(VATS)for penetrating thoracoabdominal injuries.Methods Under general anaesthesia and double-lumen tracheal intubation,VATS was carried out to examine patients with chest injuries.Those who had mild injuries received VATS combined with mini-incision surgery.Electrocoagulation or suturing was employed to control intraoperative bleeding,and then blood clots were removed.Injured diaphragm muscles were repaired,and organs with hemorrhage or ruptures were sutured or resected.The seriously injured cases underwent open surgery and intra-abdominal exploration instead.Results A total of 18 patients received the operations.Among them,15 patients underwent VATS combined with mini-incision surgery(repair of the diaphragm was performed on 15,controlling intercostal arterial bleeding on 8,repair of the lung on 2,wedge resection of the lung on 2,and coagulated hemothorax removal on 2),the other 3 were converted to open surgery for repairing the diaphragm(3),heart(1),or esophagus(1),or lobectomy(2).Abdominal surgery via the thorax were performed on 13 cases,including repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 1,repair of diaphragmatic hernia in 3,and intra-abdominal exploration in 7.Five patients received open surgery(pancreatic neoplasty in 1,repair of the liver in 1,lienectomy in 1,gastrorrhaphy in 2,and repair of the caul and mesenterium in 3).One patient who had multi-organ penetrating injuries died of hemorrhagic shock,circulatory failure,and DIC after open thoracic and abdominal surgeries.The mean operation time in this series was(125?44)minutes(ranged from 45 to 220),and the mean blood loss was(1089?582)ml(500 to 10 000 ml).Twenty-four hours after the operation,the mean volume of chest drainage was(234?75)ml(100 to 350 ml)in the first 24 hours after the operation.The chest drainage tube was withdrawn 2.5(2 to 5)days postoperation.The patients expelled gas in 1 to 4 days(mean,2 days).Totally,12 patients were followed up for 3 to 12 months(mean,6 months),during which none of them had trauma-related complications.Conclusion VATS combined with mini-incision surgery is safe and effective for patients with thoracoabdominal injuries,if the cases were carefully selected.

The addition of nature substances such as soybean oil, carrot extract, tomato extract, wastes of tobacco industry and citrus molasses to growth medium was shown to strengthen the formation of Coenzyme Q 10 Some of these substances act as precursors of Coenzyme Q 10 and Beta Carotene, and others such as wastes of tobacco industry and Beta Carotene act as inhibitors of Beta Carotene; they all can strengthen the formation of Coenzyme Q 10 Immediately relationship between the biosynthesis of Coenzyme Q 10 and Beta Carotene has been detected

Objective To explore the necessity of inferior vena cava(IVC) filter implantation during catheter directed thrombolysis (CDT) for acute deep vein thrombosis (DVT). Method Ninety-three patients with acute DVT were reviewed from Nov. 2006 to Dec. 2008. There were 35 men and 58 women, age averaging at (60 ±29) year old, treated with CDT followed by percutaneous transluminal angioplasty ( PTA). The course of DVT was from 5 h ～ 15 d (6. 28 ±7.08) d with 80 left lower limbs and 13 right lower limbs involved. Results There were 30 patients with prior IVC filter implanted compared with 63 patients without filters (67. 7% ,63/93). Among the patients without filter, there were 93. 6% (59/63) left lower limbs. DSA was redone after thrombolysis. Seventy-seven iliacfemoral thrombosis was resolved completely and stenosis or occlusion of the iliac vein were found in 90. 9% (70/77) cases. Endovascular treatment was performed in 57 patients. There was no patients suffering from symptomatic pulmonary embolism (PE). PE was found in 3 cases with a filter and 1 case without filter was suspected of PE on pulmonary CTA after treatment. Conclusion It is not necessary to routinely place an IVC filter during CDT for treating DVT on left lower limb when the thrombosis is not involing the IVC.

Objective To evaluate the results of endovascular intervention for infrapopliteal arterial occlusion in 40 patients. Methods There were 41 affected limbs in these 40 patients receiving 44 times of endovascular intervention for infrapopliteal arterial occlusion during Nov. 2006 and Dec. 2007. The average age was 76±6. The ABI(ankle brachial index)before intervention was 0.39±0.20 in anterior tibial artery and 0.39±0.23 in posterior tibial artery. CLI (critical limb ischemia) was 80.49% (33/41). Results The after intervention ABI increased by 0.43±0.22 (P<0.01) in anterior tibial artery and 0.43±0.25(P<0.01)in posterior tibial artery. 35 patients (36 limbs) were followed-up for (6±3) months. The limbs of Fontaine Ⅰ and Fontaine Ⅱ A were 28 (77.78%), CLI decreased to 19.44% (7/36) (P<0.01). At follow-up the ABI in anterior tibial artery was 0.63±0.22 and 0.56±0.22 in posterior tibial artery. The difference were all significant when compared with that before intervention and after intervention. The perioperative amputation rate was 0. The perioperative mortality rate was 2.5%. The total mortality rate was 15%. The limb salvage rate were 100%. Conclusion The effect of endovascular intervention for infrapopliteal arterial occlusion is satisfactory.

Objective To evaluate imaging findings and treatment experience in central venous stenosis without a history of previous catheterization in hemodialysis patients. Methods Clinical data of 5 haemodialysis cases of central vein stenosis without a previous catheterization history in our hospital from July 2006 to July 2008 were analyzed retrospectively. Results Patients were three women and two men aged 43 to 65 years with mean age(53±8)years and all had arm swelling as the main complaint.The vascular accesses were located at the wrist in all the patients.The mean duration of the vascular accesses from the time of creation was(33.6±35.4)months.Venography showed occlusion in 2 cases and stenosis in 3 cages of central vein including 1 case of stenosis in brachiocephalic vein.1 case of stenosis beth in branchiocephalic vein and subclavian vein,1 case of stenosis in two segments of subclavian vein.The stenosis of branchiocephalic vein was fixed anterior to the tracheal and CT showed the compression of the vein by the aorta.Symptoms were resolved by the treatment of PTA.subclavian vein-contralateral subclavian vein bypass and ligation of the access. Conclusions Central venous stenosis in haemodialysis patients without a history of catheterization may be due to the intimal hyperplasia of the compression site or valve which is accelerated by the high flow of vascular access.Venography is the first choice for the diagnosis and the current management of central venous stenosis is far from being effective for the long term.

Objective:To evaluate the relationship between breast reconstruction and postoperative complications by meta-analysis.Methods:Through a defined search strategy, related literature was collected in databases from PubMed, MEDLINE, EMBASE, Cochrane, CNKI, Wanfang Database and VIP Database, from January 1990 to November 2017. Data were extracted and each merged data was analyzed using RevMan 5.3 software. The postoperative complications between transverse rectus abdominis musculocutaneous-flap (TRAM) and deep inferior epigastric perforatorflap (DIEP), TRAM and latissimus dorsiflap (LDF), LDF and LDF+ prosthesis, LDF+ prosthesis and simple prosthesis implantation were compared.Results:Twenty-nine papers met inclusion criteria of our study. The Meta-analysis results showed that the risk of local flap necrosis, seroma, infection, fat liquefaction, abdominal wall hernia and abdominal bulging in TRAM group were higher than those in DIEP group, and the differences were significant. There was no significant difference in total flap necrosis, wound dehiscence, venous congestion between the two groups; the risk of total flap necrosis, wound dehiscence and infection in TRAM group were higher than those in LDF group, and the differences were significant. The risk of seroma in TRAM group was lower than that in LDF group, and the differences were significant. There was no significant difference in fat liquefaction between the two groups; there was no significant difference in the postoperative complications between LDF group and LDF+ prosthesis group; the risk of seroma in LDF+ prosthetic group was higher than that in prosthetic group, and the differences was significant. The risk of prosthetic capsular contracture and prosthesis displacement in LDF+ prosthetic group were lower than those in prosthetic group, and the differences were significant. There was no significant difference in prosthesis exposure and infection between the two groups.Conclusions:DIEP has most of the advantages of TRAM and fewer complications. It plays an important role in breast reconstruction in the future. We should make a choice of breast reconstruction methods according to the patient＇s conditions as far as possible in clinical practice.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.
