OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

Accurate assessment of the degree of coronary artery stenosis is very important to guide the revascularization of patients with coronary heart disease. In recent years, functional assessment of the impact of coronary artery stenosis on the distal myocardium is changing the traditional concept of revascularization. The superiority of the fractional flow reserve(FFR) in guiding coronary interventional therapy has been widely verified in clinical practice. Due to its invasive operation, high cost, and high side effects of vasodilators during examinations, its application in my country is relatively limited. Quantitative flow ratio as a new, noninvasive, and rapid tool for assessing coronary stenosis, is being favored by researchers. This article reviews the clinical research progress of quantitative flow ratio and prospects its future clinical applications.

Objective To explore the operative methods and indications of duodenoscopic papillotomy during the course of operation(IEPT)for cholelithiasis.Methods Cholecystectomy was firstly conducted under the condition of laparoscopy or open laparotomy.For the gross choledochus,the common bile duct was cut open to clear the stones.The ureteric catheter and zebra guidewire were inserted into the common bile duct and duodenum.Then they were inserted via duodenoscopy into thepapillum of duodenum.The papillary stenosis was removed with electro-knife by pin-head-like and arch-like to track along the ureteric catheter and zebra guidewire.For the tiny choledochus,the ureterie catheter and zebra guidewire were inserted via the cholecystic duct remnant into the common bile duct and duodenum.Then they were inserted via duodenoscopy to perform papillotomy to clear the stones of the common bile duct with the reticulation and the balloon of duodenoscopy.Results Forthe gross choledochus,IEPT in laparoscopy was successful in 45 cases and the other 2 received other operation.IEPT in open laparotomy was successful in 5 cases.For the tiny choledochus,IEPT in laparoscopy was successful in 73 cases and the other 1 underwent other operation.IEPT in open laparotomy was successfulin 2 cases.Conclusion If patients are suitable,IEPT is safe and effective in the hands of skilled endoscopiests for laparoscopy and open laparotomy.

Objective To evaluate combination of cholcdochoscopy or duodenoscopy with therapeutic laparoscopy (LCDCS) in treatment of detail choledochus stones. Methods Laparoscopic cholecystectomy was firstly performed and followed by choledochoscopy or duodenoscopy. Procedures of therapeutic choledochoscopy were as follows: choledochoscopic exploration via cystic duct remnant, choledochotomy, electrohydralic lithothipsy, drainage of bile duct with ureteral catheter via cystic duct remnant, T-tube drainage, or the suture of duct incision. Procedures of therapeutic duodenoscopy were as follows: access to the common bile duct and duodenum through ureteric catheter and zebra guidewire via cholecystic duct remnant, duodenoscopy via oral cavity into the duodenum papilla, papillotomy with needle-knife or arch-like electro-knife along the ureteric catheter or zebra guidewire, and stone clearance in the common bile duct with the reticulation and balloon of duodenescopy. Results Combination therapy were given to 191 cholelithiasis patients with detail choledochus stones. Combined choledochoscopy were performed in 117 patients. Stones were completely removed and average operation time was 114 min. Bile leakage occurred in 7 cases, but was cured with drainage. Postoperative imaging showed 2 cases of bile duct stenosis at primary closure of duct incision. Combined duodenescopic procedures were performed in 74 patients. Papillotomy and stone clearance were successfully performed in 68 patients, 5 others of whom underwent successful papillotomy only, and another underwent other operations. Average operation time was 97 min. Post-operation mild acut pancreatitis developed in 6 patients. No perforation of intestine or bile duct, bleeding, severe pancreatitis, or death was observed in each group. Conclusion LCDCS was safe and effective with appropriate indications.

Objective To observe the clinical effect on sleep improvement about acupoint application in treating the chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.Methods A total of 68 patients with chronic insomnia with Liver-stagnation and Spleen-deficiency Syndrome were randomly and blindly divided into treatment group and control group by registration order. In the treatment process, 1 was eliminated and 33 were completed in the treatment group, 2 were eliminated and 32 were completed in the control group. The treatment group underwentAn Mian Tietherapy half an hour before bed and the control group underwent placebo therapy in the same way of treatment group. Two groups were treated for 40 days and followed-up visit six months. The change of Pittsburgh Sleep Quality (PSQI), Index Insomnia Severity Index (ISI) and TCM Syndromes Scale were detected.Results The clinical total effective rate of treatment group was 72.7% and the control group was 9.4%, and the difference was statistically significant (χ2=46.977,P<0.01). The PSQI scores after treatment (7.55 ± 1.52vs. 13.90 ± 2.44,t=148.165), and follow up 1 month (8.97 ± 2.51vs. 13.17 ± 2.79,t=37.926) in the treatment group were significantly lower than those in the control group (P<0.01). The ISI scores after treatment (7.03 ± 3.37vs. 20.89 ± 4.40,t=73.75), and follow up 1 month (9.81 ± 3.16vs. 19.41 ± 3.66,t=40.79) in the observation group were significantly lower than those in the control group (P<0.01). The TCM Syndromes Scale scores after treatment (2.05 ± 1.09vs. 6.98 ± 1.23,t=17.116), and follow up 1 month (4.06 ± 1.59vs. 6.83 ± 0.91,t=68.055) and follow up 6 month (5.12 ± 1.84vs. 7.19 ± 1.07,t=27.716) in the observation group were significantly lower than those in the control group (P<0.01).Conclusions Acupoint application could obviously change the sleep quality and Chinese medicine symptom in chronic insomnia of Liver-stagnation and Spleen-deficiency Syndrome.

OBJECTIVETo observe the efficacy of integrative medical sequential method in treating cerebral palsy (CP) children's intelligence development, muscular tension, serum interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-alpha).

METHODSTotally 111 CP children were randomly assigned to the control group (50 cases) and the treatment group (61 cases). All patients received comprehensive rehabilitation training and intravenous dripping of Monosialotetrahexosylganglioside Sodium Injection for 10 days. But those in the treatment group additionally received Chinese medical enema for brain resuscitation, relieving rigidity of muscles and activating collaterals for 14 days. Then they started another medication cycle and lasted for a total of 6 cycles. Serum IL-6 levels and TNF-alpha contents were determined before treatment. Scoring for muscular tension, Gesell score for intelligence development, contents of serum IL-6 and TNF-alpha were assessed before and after treatment in the two groups.

RESULTSCompared with before treatment in this group, muscular tension, Gesell scores for intelligence development all decreased in the two groups (P < 0.05). As for inter-group comparison, the decrement was more obvious in the treatment group than in the control group (P < 0.05). The total effective rate was 86.9% in the treatment group and 76.0% in the control group (P < 0.05). The contents of IL-6 and TNF-alpha were obviously reduced in the treatment group and the control group after treatment (P < 0.01). The decrement was more obvious in the treatment group (P < 0.05).

CONCLUSIONThe two treatment methods were effective for CP children, but the efficacy was superior in the treatment group than in the control group, indicating integrative medical methods could play a synergistic effect and optimize the treatment program for CP.

OBJECTIVETo study the correlation between arachidonic acid (AA) and acute red blood cells damage in rats, and to build a model with hidden blood loss in vivo, and to explore the pathological mechenism of hidden blood loss.

METHODSA total of 50 male adult Sprague-Dawley rats weighing (200 ± 20) g were randomly divided into five groups (n = 10): control group and four experimental groups. The rats in the experimental groups were given 0.5 ml different concentrations of AA dilu- ents, 5, 10, 20, 40 mmol/L respectively. The blood samples were collected from orbital venous at the beginning and 24, 48, 72 hours after administration. Then the changes of hemoglobin (Hb) ,red blood cell count (RBC), glutathione peroxidase (GSH- PX) activity, total superoxide dismutase (T-SOD) activity and hydrogen peroxide (H202) in the blood samples were tested.

RESULTSSignificant hidden blood loss occurred when the concentration was 10 mmol/L in the experimental group, with the RBC and Hb sharply reduced in blood samples. The Hb and RBC were reduced in all the experimental groups and control group at 24 hours after administration, while in the experimental groups they changed more obviously. The GSH-PX activity, T-SOD activity and H₂O₂were also significantly reduced in all groups, and the changes showed significant differences. The Hb and RBC were relatively stable in the control group and the experimental groups at 48 hours after administration; while GSH-PX activity, T-SOD activity and H₂O₂were all significantly decreased, and the changes in the experimental groups were more notable.

CONCLUSIONElevated levels of AA in the blood causes oxidative stress in the red blood cells, leading to the damage of red blood cells and hemoglobin, which is responsible for hidden blood loss.

Objective To retrospectively analyse the anterior and posterior surgical approaches in treatment of unstable burst thoracolumbar fractures and compare radiographic measurement parameters of beth surgical techniques so as to provide references for surgical treatment of such kind of fracture. Methods The study selected 41 patients with unstable thoracolumbar fracture treated with either anterior neurodecomprossion and fixation (n=19) or posterior reposition and internal fixation by pedicle screw (n=22) from January 2003 to December 2005. All patients were followed up for 24-48 months ( mean 38 months) and divided into anterior approach group and posterior approach group. Sagittal alignment was assessed by the Cobb angle depending on lateral radiographs. Results The Cobb angle of the anterior approach group was average 27.3°on admission but 3.1°postoperatively and 4.6° at follow-up; while the Cobb angle of posterior approach was average 26.1° on admission, 3.0°postoperatively and 12.5°at follow-up. There was no statistical difference between Cobb angle on admission and postoperative one (P>0.05) but showed significant differences between them at follow-up ( P<0.01). Conclusion The anterior surgical approach can consistently yield better maintenance of kyphotic correction compared with the posterior surgical approach.
