Objective To compare the clinical efficacies of warm needling versus salt moxibustion in treating knee osteoarthritis. Methods One hundred and twenty patients with knee osteoarthritis were randomly allocated to groupsⅠ andⅡ, and control group, 40 cases each. GroupⅠ received salt moxibustion; groupⅡ, warm needling; the control group, routine medication. After 4 weeks of treatment, the Lysholm Knee Scoring Scale scores, the VAS scores, the quality of life scores and the clinical therapeutic effects were compared between the three groups.Results There were statistically significant pre-/post-treatment differences in the Lysholm Knee Scoring Scale scores, the VAS scores and the quality of life scores in the three groups (P<0.05). There were statistically significant post-treatment differences in the Lysholm Knee Scoring Scale scores and the VAS scores between groupⅠ orⅡ and the control group (P<0.05). The total efficacy rate was 90.0% in groupⅠ, 87.5% in groupⅡ and 70.0% in the control group. There was a statistically significant difference in total efficacy rate between groupⅠ orⅡ and the control group (P<0.05).Conclusions Warm needling and salt moxibustion are both effective way to treat knee osteoarthritis and have equal therapeutic effects.

Objective To compare the stability effect of the fixation segment using the new test system based robotics to simulate the complex human movement at natural state about the three-level fixa-tion by using four, five or six pedicle screws in treatment of thoracolumbar burst fractures. Methods Six human cadaveric spines were dissected from T_(11)-L_3. The inferior half part of L_1 vertebral bodies and L_1-L_2 dises were resected to mimie an unstable L_1 burst fracture with loss of anterior column support. Specimens were tested in accordance with the following order:intact, 4,5 and 6 pedicle screws fixation at the three-level fixation. The range of motion (ROM) of the fixation segment (T_(11)-L_3) was measured with the six-freedom degree robotics system controlled by mixed force and displacement during flexion, exten-sion, lateral bending and axial torsion, when the stiffness was calculated. One-way statistieal analysis was used for analyzing the collected data. Results With increased number of screws, the ROM of the fixa-tion segment (T_(11)-L_3) was gradually decreased and the stiffness gradually increased. The ROM under ax-ial rotation of six and five screws group became smaller than four screws group (P < 0.05). The stiffness under axial rotation of six screws group was higher than four screws group (P < 0.05). There was no sta-tistical difference between five screws group and four screws group in regard of the stiffness in axial rota-tion (P > 0.05). There were no significant differences in ROM and stiffness under six different loading directions between six screws group and five screws group (P > 0.05). No statistical difference was observed for three fixation modes in aspects of ROMs and stiffness under flexion-extension or lateral ben-ding (P > 0.05). Conclusions Three-level fixation of burst fractures with five or six screws offers im-proved biomechanical stability compared with traditional four screws fixation. But the difference is insig-nificant between six and five screws fixations.

Objective To evaluate the clinical value and safety of prelocalization with ultrasound during internal jugular vein cannulation. Methods One hundred patients scheduled for internal jugular vein cannulation from February 2009 to April 2010 were divided into two groups by random digits table with 50 cases in each group. Group U patients were performed by ultrasound-prelocalization method and group T patients were performed by traditional technique. The first successful punctures and the first successful catheterization,puncture times,operation time and complications were recorded. Results Compared with group T, puncture times,operation time and complications were lower in group U [(1.0±0.5) times vs.(2.1±1.4) times;(4.5±1.2) min vs.(6.8±1.6) min;0 vs. 12.0%(6/50)](P＜ 0.01 ). The first successful punctures and the first successful catheterization [96.0% (48/50) and 95.8% (46/48)] in group U were obviously higher than those in group T [ 72.0%(36/50) and 77.8% (28/36)] (P ＜ 0.01 ). Two cases were failed in group T. Conclusion Ultrasound-prelocalization technique is simply and practically method for internal jugular vein cannulation under the stable body position.

Objective To investigate the clinical value of laparoscopic totally extraperitoneal inguinal hernia repair.Methods One hundred and twenty patients who suffered from inguinal hernia were treated with laparoscopic totally extraperitoneal inguinal hernia repair.The operation time,wound pain,postoperative recovery of independent function,complications and recurrence rate were studied.Results One hundred and seventeen patients of inguinal hernia were performed the operation successfully,while 3 cases were converted to transabdominal preperitoneal prosthetic.Five cases of pneumoscrotum,were used in surgery to put the needle into the subcutaneous emphysema disappeared after the gas.The mean operative time 30-125 (46 ± 18) min,the postoperative stay was 2-7 (4.5 ± 1.2) d.The patients were postoperative follow-up for 1-22 months.All the patients without postoperative hydrocele,no postoperative recurrence.Conclusions Laparoscopic totally extraperitoneal inguinal hernia repair is safe with less complications,less invasive,low recurrence rate and excellent therapeutic effect and bilateral inguinal hemia repair at the same time.

Objective To evaluate the clinical and radiological results of Phlios plate and Multiloc nail in treatment of proximal humerus fractures.Methods From February 2013 to December 2015,data of 37 cases of proximal humerus fractures who were treated by reduction and fixation using Phlios plate or Multiloc nail were retrospectively analyzed.In group one (Phlios plate),there were 10 males and 8 females,with an average age of 56.3±5.8 years,including 7 cases of Neer 2-part surgical neck fracture,6 cases of Neer 3-part fracture,4 cases of Neer 4-part fracture,and 1 case of fracture-dislocation.In group two (Multiloc nail),there were 8 males and 11 females,with an average age of 57.2±7.4 years,including 8 cases of Neer 2-part surgical neck fracture,9 cases of Neer 3-part fracture,1 case of Neer 4-part fracture,and 1 case of fracture-dislocation.Operation time,range of motion of shoulder joint,visual analogue scale (VAS) pain score,American Shoulder & Elbow Surgeon (ASES) score and ConstantMurley score were collected.Results All 37 patients were followed up for an average period of 15.5 months (range,12-36 months).The average bone healing time were 2.5±0.5 months (range,2-3 months)and 2.2±0.5 months (range,1.5-3 months) in the plate and nail group respectively.At the latest follow-up,average VAS score was 0.4±0.6 (range,0-2),the ASES score aver aged 85.4±6.8 points (range,73-96),Constant-Murley score averaged 83.4±7.3 points (range,71-94),and external rotation averaged 30.8°±10.0° (range,10°-50°) in plate group,while average VAS score was 0.2±0.4 (range,0-1),ASES score averaged 89.7± 5.6 points (range,80-98),Constant-Murley score averaged 88.5±6.8 points (range,76-98),and external rotation averaged 40.3°± 7.9° (range,20°-50°) in the intramedullary nailing group.One case had partial necrosis of humeral head in the plate group,while 1 case suffered absorption of the greater tuberosity in the nail group,with the complication rate of 5.6％ (1/18) and 5.3％ (1/19) respectively,without significant difference.The internal and external rotation degrees,ASES and Constant-Murley scores were better in nail group than those in plate group for 2-part fractures,while the forward elevation and abduction degrees were similar.Conclusion Similar results were achieved for the treatment of proximal humeral fractures by Phlios plate and Multiloc nail.The Multiloc nailing group had achieved superior outcomes in Neer-2-part proximal humeral fractures.

Objective To study the effect of Shenlingbaizhu Pills on hyperlipidemia and gut microbiota in guinea pigs, providing data support for the treatment of hyperlipidemia from the " spleen" . Methods Guinea pigs were randomly divided into control group, model group, ezetimibe group, Shenlingbaizhu Pills high and low dose groups, with 12 guinea pigs for each group. Guinea pig models of hyperlipidemia were established with high fat diet for 8 weeks. Oral administration of the drug began at the fifth week and continued for 4 weeks. The serum lipid levels of guinea pigs were determined after final administration. The pathological changes of liver tissue were observed by HE staining. The mRNA expression levels of ATP binding cassette ( ABC ) A1 in liver, Niemann Pick C1 like 1 ( NPC1L1) and ABCG5/8 in small intestine were detected by realtime PCR. 16S rDNA sequencing was used to detect changes of gut microbiotas in guinea pigs. Results Shenlingbaizhu Pills significantly reduced the serum triglyceride, total cholesterol, and low density lipoprotein-cholesterol levels in guinea pigs with hyperlipidemia ( P＜0. 01 or P＜0.05). The pathological degree of fatty liver was improved obviously by Shenlingbaizhu Pills. Shenlingbaizhu Pills could reduce the mRNA expression level of NPC1L1 of small intestine and increase the level of liver ABCA1 and small intestine ABCG5/8 (P＜0.01 or P＜0.05). At the phylum level, Shenlingbaizhu Pills could reduce the proportion of verrucomicrobia of guinea pigs in model group (P＜0.01); At the genus level, Shenlingbaizhu Pills could increase the proportions of erysipelotrichaceae＿unclassified, ruminococcus＿1, and ileibacterium of guinea pigs in model group (P＜0. 01 or P＜0. 05 ), reduce the proportion of akkermansia and eubacterium＿coprostanoligenes＿group ( P＜0.01). Conclusion Shenlingbaizhu Pills had significantly therapeutic effect on hyperlipidemia, and its specific mechanism was related to the regulation of cholesterol transport and intestinal flora.
