OBJECTIVETo study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

METHODSTwenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.5 years old. The duration from injury to surgery ranged from 2 hours to 2 months, and the mean time was 6 days. All the patients had collateral ligament injuries combined with fracture of the metacarpophalangeal joint of the thumb. Thirteen patients had injuries in the right hand and 9 patients had injuries in the left hand. There were 18 cases of closed wound and 4 cases of open wound. Eighteen patients had fresh injuries (< 2 weeks) and 4 had old injuries (> 2 weeks). Sixteen patients had injuries in the ulnar collateral ligament of the thumb combined with fracture, 6 patients had radial collateral ligament injuries of the thumb combined with fracture, 4 cases of which were complicated with injuries of abductor pollicis brevis and the end of the flexor pollicis brevis tender. The size of the avulsed fragment was about 3.0 mm x 4.0 mm to 6.0 mm x 7.0 mm.

RESULTSThe incisions of 22 patients healed by first intention. The follow-up periods ranged from 6 months to 5 years old,with an average of 2.5 years old. The thumb function was evaluated by Saetta and other evaluation criteria, and 20 patients got an excellent result and 2 good.

CONCLUSIONThe application of one-hole microplate internal fixation in treating collateral ligament injuries with fracture of the metacarpophalangeal joint of the thumb is an effective method.

OBJECTIVETo study the formulation and preparation of ampelopsin liposomes and evaluate their quality.

METHODThe liposomes were prepared by a film-ultrasonic dispersion technique. Served as quota with the entrapment ratio and appearance and diameter of the liposomes, the optimal formulation and preparation were selected by means of an uniform design test. The appearance of liposomes was observed by micrography. The diameter and electric charge of surface were determined by granularity mensuration instrument. The entrapment ratio and the leakage rate of ampelopsin liposome were determined by means of dialyze. The content of ampelopsin was determined by UV.

RESULTThe result of electron micrography and the size distribution showed that the liposomes were similar to spherical small unilamellar vesicles. The mean diameter was (258.2 +/- 51.2) nm and the electric charge of surface is 19.0 mV. The entrapment ratio of ampelopsin liposomes was 62. 3% and the lecithoid oxidative rate was 0.83% (n = 3).

CONCLUSIONThe selected formulation and preparation of ampelopsin liposomes is efficient and practicable.

Objective To observe the curative effect of Fuzhengxiaojia decoction on precancerous lesion of gastric cancer (PLGC).Methods We randomly divided 44 patients with PLGC in our hospital into control group (n=22)and treatment group (n=22).The control group was given 4 Weifuchun tablets each time and three times per day and while the treatment group was given one Fuzhengxiaojia decoction of 400 mL besides the medication of the control group.They were treated for two courses,one course lasting for one month.Results Superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),IgG,IgM and IgA in the two groups had no significant differences before treatment (P＞0.05).After treatment,compared with those in the control group,SOD (t=2.144,P=0.044)and GSH-Px (t=2.322,P=0.030)increased,while MDA(t=3.096, P=0.005),IgG(t=2.421,P=0.025),IgM(t=3.377,P=0.003)and IgA (t=2.521,P=0.020)decreased. The main symptom scores in the two groups did not significantly differ before treatment (P＜0.05).After treatment, compared with those in the control group,the scores for main symptoms like reduced food intake (t=3.924,P＜0.001),stomach noise (t=4.161,P＜0.001)and gastric or hypochondriac swelling (t=2.881,P＜0.009) decreased in the treatment group.The rate of effective cases was higher than that in the control group (χ2=4.539, P=0.033).Conclusion The effect of Weifuchun combined with Fuzhengxiaojia prescriptions in treating PLGC is better than Weifuchun alone,which is related to improving redox and immunoglobulin.

Objective To assess the laparoscopic technique combined with open surgical technique in pyeloplasty.Methods Overall,45 patients with ureteropelvic junction obstruction underwent laparo- scopic dissection of the renal pelvis and upper ureter transperitoneally,and pyeloplasty was performed through a expanded trocar-incision(extension of 1-2 cm)as open surgery was performed.Results The opera- tion was successful in all 45 patients.The mean operative time was 58 min(range,40-85 min),and the mean blood loss was 22 ml(range,15-30 ml).No complication was observed during and after operation. Follow-up for 3-36 months was available in 34 patients.Intravenous urography(IVU)showed no obstruc- tion of the anastomotic stoma,and B-ultrasound indicated relief of hydronephrosis.Conclusions Laparo- scopic approach combined with open surgery in pyeloplasty is an effective way to treat ureteropelvic junction obstruction.This technique can simplify the operative manipulation and shorten the operative time without more trauma to the patients.It is worth general application in clinical practice.

·AIM:To investigate and analyse the prevalence and risk factors associated with diabetic retinopathy severity in Qingdao. ·METHODS: This survey consisted of the 2 following parts: 2859 community residents aged >60 years old and 4275 patients with T2DM who were older than 30 years old in Qingdao. Ophthalmic examinations were performed on all patients. A questionnaire was used to obtain the patient's age and gender, the duration of diabetes mellitus(DM), glycaemic control and their knowledge of diabetic retinopathy ( DR ). Blood pressure and haemoglobin levels were recorded. All included patients underwent a comprehensive ophthalmic examination that included a fundus examination and retinal photographs and that assigned a grade for the severity of retinopathy according to the Early Treatment Diabetic Retinopathy Study (ETDRS) severity scale. Patients with severe non-proliferative or proliferative diabetic retinopathy and clinically significant macular edema ( CSME ) required ophthalmic therapy were assigned to the need-treatment group, while the remaining patients with DR were assigned to the need-observation group. Correlation and regression analyses were performed to determine the required-treatment rate and risk factors for DR. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) after adjustment for age, gender and the duration of diabetes. ·RESULTS: DR was present in 334 (11. 68% ) of the 2859 community residents aged > 60 years old and 1097 (25. 66% ) of the 4275 hospital patients with T2DM, and 48 (14. 81% ) of the residents and 172 ( 15. 68% ) of the hospital patients required ophthalmic therapy. In univariate and multivariate logistic analyses, factors including the age of the patients (51-60 years old: OR, 1. 68; 95% CI, 1. 21-1. 72; 61-70 years old: OR, 1. 55;95% CI, 1. 38-1. 76), the duration of diabetes (11-15 years:OR, 2. 61; 95% CI, 1. 51-4. 72; >15 years: OR, 4. 15; 95% CI, 2. 32-5. 77), glycaemic control (medium: OR, 2. 51;95%CI,1.98-3.92;poor:OR,4.69;95%CI,3.39-6.95), and knowledge of DR ( did not understand: OR, 1. 45;95%CI, 1. 21-1. 95) were significantly associated with the required-treatment rate in DR, while gender, low and advanced age ( 31-50 years old and >70 years old ), duration of disease (<10y), hypertension, and insulin treatment did not. ·CONCLUSION: The prevalence rate and the required-treatment rate in DR in Qingdao are relatively high. Being aged 51-70 years old and having a duration of diabetes>10y, poor glycaemic control and a lack of knowledge of DR were found to be potential risk factors that increased the rate of required ophthalmic therapy in patients with DR. In patients with T2DM who were aged 51-70 years old, we found that focusing on using science and education to strengthen the patients' knowledge of DR, establishing specifications for a community DR screening system, and effectively implementing early intervention in the community of DR - affected individuals were particularly important for preventing and controlling the high DR prevalence and the high rate of DR-associated blindness

OBJECTIVETo discuss the clinical experience of laparoscopic radical prostatectomy by extraperitoneal approach.

METHODSFive patients with localized prostate cancer underwent laparoscopic radical prostatectomy by extraperitoneal approach. The surgical procedure included the excision of the prostate, seminal vesicles, ampulla ductus deferentis and part of the bladder neck, followed by urethrovesical anastomosis.

RESULTSAll the operations were successful. The mean operation time was 350 minutes (ranging from 270 to 420 mm); the mean estimated blood loss was 480 ml (ranging from 250 to 600 ml). The bowel activity was recovered with 48 hours after surgery. The patients were ambulant between the 2nd and 3rd postoperative days. The mean hospital stay was 8. 5 days (ranging from 7 to 12 days). The 3-8 months follow-up found no incontinence of urine; of the 3 preoperatively potent patients, 2 were able to have sexual intercourse; strictured stoma was reported in only 1 case.

CONCLUSIONThe extraperitoneal laparoscopic radical prostatectomy, keeping the procedure out of the peritoneal cavity, with small incision and rapid recovery, may be considered as a promising surgical method for patients with localized prostate cancer.

OBJECTIVETo report replantation of amputated ear with microtechnique in 5 cases.

METHODSFrom 2002 to 2005, 5 totally amputated ears were replanted and 4 obediently, 1 retrogressively. In every case, 1-2 arteries and 1-3 veins were anastomosed. Seven vessels were detective and 1-6 cm vessels were transplanted from forearm or dorsal side of hand. Amputated ears obtained blood supply again in about 6-10 hours after injury and exploration was enforced for venous crisis in 2 cases, and bloodletting in 1 case.

RESULTSAll 5 cases survived. Auricles possess perfect shape, no pigmentation, slight atrophy and perfect sensation.

CONCLUSIONSAmputated ear should be replanted as long as no obvious contusion occurred, and the keys to prevent vascular crisis are cutting off unhealthy vessels, grafting superficial veins for bridging, and the high quality of vascular anastomosis.

BACKGROUNDLaparoscopic dismembered pyeloplasty with less trauma than open surgery is commonly performed for ureteropelvic junction obstruction despite a longer operating time and a long learning curve. We describe in this paper a new technique, which combines laparoscopic and open procedure in dismembered pyeloplasty, that we have developed in 51 patients and achieved excellent results.

METHODSThe surgical procedure can be divided into two steps: laparoscopic dissection of the renal pelvis and proximal ureter transperitoneally; then accomplishing the pyeloplasty through the extended port incision above the ureteropelvic junction as in open surgery.

RESULTSAll 51 operations were successful without conversion to open surgery. No intraoperative complications were observed. The operating time was 40 minutes to 90 minutes with an average of 57.5 minutes. The estimated blood loss was 15 ml to 30 ml with an average of 21.2 ml. Aberrant artery vessel and primary stricture as the cause of ureteropelvic junction obstruction was noted in 2 and 49 patients, respectively. Thirty-nine patients had fever to differing extents in the 4 days postoperation and no severe infection was observed. Four patients had urinary leakage with their drains being retained for 6 days, 6 days, 5 days or 8 days after the operation. The mean followup was 10.8 months (range 3 months to 36 months). The followup showed good results with symptom resolution in all the patients. Renal ultrasonography demonstrated that the average separation of the collecting systems decreased from preoperative 2.7 cm (range 2.0 cm to 4.7 cm) to postoperative 1.5 cm (range 1.0 cm to 2.3 cm). Excretory urography at 3 months postoperatively showed improved drainage. Of the 51 patients, 35 underwent two or more excretory urograms, demonstrating stable renal function, improved drainage and no evidence of recurrent obstruction. At the last followup visit, each patient was doing well.

CONCLUSIONSCombination of laparoscopic and open procedure in dismembered pyeloplasty offers a simpler, timesaving method in a minimally invasive fashion with low morbidity for patients with ureteropelvic junction obstruction. Ensuring quality of repair, the method provides a minimally invasive alternative with good results. It is worth future clinical application.
