BACKGROUND: The researches of Pulling and Rotating Oblique Pulling Manipulation focus on clinical research and biomechanical changes of lumbar functional units, and the mechanical characteristics of manipulation are little reported.OBJECTIVE: To study the characteristics of the Pulling and Rotating Oblique Pulling Manipulation by digital method, so as to provide quantitative basis for inheritance, teaching and learning, promotion, and basic research of the manipulation.METHODS: The force-time curve and the force of the manipulators were tested and recorded with the multi-point membrane pressure measurement system. The kinetic parameters (the average load force, the average minimum force and the maximum impact force) were shown. The values of = the flip time, flip speed and impulse were measured by the test analysis system.RESULTS AND CONCLUSION: (1) The average load force was (145.86±34.80) N, duration was (1.43±0.46) s, the average minimum force was (72.24±13.87) N, the maximum impact force was (446.21±143.98) N, the flip time was (0.55±0.15) s, flip speed was (914.52±259.18) N/s, and the impulse was (256.21±82.30) N?s. (2) The rising slope of the impulse was (93.96±6.94), and the falling slope was (-82.70±26.10). (3) To conclude, the characteristics of manipulation from hand are analyzed in views of digitization, which provides an objective evaluation index for Lin's manipulation.

Objective To compare the efficiency and safety of double-channel flexible ureteroscopy and electronic flexible ureteroscopy.Methods From April 2007 to 2016 July, clinical data of 836 cases flexible ureteroscopic holmium laser lithotripsy were collected. All the patients were randomly divided into electronic lfexible ureteroscopy group (n = 427) and double-channel lfexible ureteroscopy group (n = 409), the operation time, success rate of surgery, complications, residual stone rate of the two groups were compared.Results The success rate of surgery was 92.5% and 83.6% of the two groups respectively, the difference was significant (P < 0.05); postoperative systemic inlfammatory response syndrome (SIRS) were occurred in 10 cases and 13 cases respectively, which were cured and the difference was not statistically significant (P > 0.05); the average operation time was (81.1 ± 7.9) min and (95.3 ± 7.6) min respectively, the difference was significant (P < 0.05); The formation of stone street of electronic lfexible ureteroscopy group and double-channel lfexible ureteroscopy group were 17 cases and 25 cases. The residual stone rate of electronic flexible ureteroscopy group and double-channel flexible ureteroscopy group were 6 cases and 8 cases, of them were cleared after extracorporeal shockwave lithotrips (ESWL). There were no difference between the two groups (P > 0.05).Conclusion Both double-channel lfexible ureteroscopy and electronic lfexible ureteroscopy are effective and safe therapeutic modalities. Electronic flexible ureteroscopy is better than double-channel lfexible ureteroscopy in success rate of surgery because of its high deifnition and lfexible operation.

Objective To explore the risk factors ,prevention and treatment of the occurrence of perirenal hematoma after flexible lithotripsy. Methods We retrospectively analyzed the clinical data of 18 patients with symptomatic perirenal hematoma from 1259 who had undergone ureteral flexible lithotripsy in our hospital during the period of April 2007 to April 2016. Of the 18 patients,7 were complicated with diabetes mellitus,11 had urinary tract infection;15 were female,and 3 were male. Results Perirenal hematoma was confirmed by B ultrasound and CT,which situated on the Posterolateral side of the kidney in 8 patients,and on the lower pole and abdominal side in 10. Hematoma depth was 2.6-15.3 cm(average was 5.2 cm). The hematoma?related symptoms gradually disappeared in 11 patients 7 to 14 days after they received conservative treatment. 5 recovered gradually 15 days after undergoing hematoma puncture and drainage ,and 2 recovered 36 days after receiving open surgery for removal of hematoma. Conclusions Female,diabetes,urinary tract infection,bigger stone size,prolonged surgical duration,and infected stones were the risk factors for perinephric hematoma related to ureteroscopic lithotripsy. Full preoperative preparation ,effective anti?infection ,intraoperative improvement of calculus?breaking skills and use of large caliber semirigid through sheath,low pressure perfusion,shorter surgical duration,and staging surgery are effective ways to reduce the occurrence of perirenal hematoma.

Objective To measure the thumb manipulative forces of Lin cervical rotation manipulation during cracking sounds,and provide quantitative basis for its inheritance,teaching and learning,promotion and basic research of the manipulation.Methods The thumb manipulative force of Lin cervical rotation manipulation and traditional cervical rotation manipulation during cracking sounds were tested and recorded with a multi-film pressure measurement system.Result There was statistically significant difference between the maximum thumb manipulative force of the hand used frequently and the hand used infrequently (P < 0.05).The maximum thumb manipulative force of Lin cervical rotational manipulation is lower than the traditional cervical rotation manipulation (P < 0.05).Conclusion Whether inIN traditional or Lin cervical rotation manipulation,the maximum thumb manipulative force of the hand used frequently is more than the hand used infrequently.Lin cervical rotation manipulation has better ergonomic characteristics of biological engineering,safer,more low energy consumption practices.

Objective To evaluate the therapeutic effects and to summarize the clinical experience of benign prostatic hypertrophy(BPH) with inguinal hernia in the elderly 70-89 years. Methods Clinical data of 32 patients 70-89 years old simultaneously undergone transurethral resection of prostate (TURP) and plug-mesh tension-free hernia repair from July 2000 to May 2005 were retrospectively analyzed and followed up. Results The average operating time was (85.0?12.8)minutes, the average blood loss was (90.0? 18.7 )ml. No postoperative death or life threatening complications were revealed. By 7-40 months of following up reported that there were no recurrence of hernia as well as no incontinence and urethral stenosis or other complications. IPSS,maximal flow rate and residual urine were evidently improved after operation. Conclusion Combined TURP and plug-mesh tension-free hernia repair is a safe and effective procedure for the elderly patients.

Objective To investigate the clinical characteristics of Takayasu's arteritis (TA) with pulmonary hypertension (PAH) in order to improve the diagnosis and treatment earlier. Methods Twelve out of 191 patients with TA registered in Peking Union Medical College Hospital from 1987 to 2007 were diagnosed as PAH, the clinical data of 12 patients were analyzed. Results Ten patients were females. The range of age were from 14 to 47 years old, the average age was (27±10) years old. Eleven patients had the clinical manifestations or/and signs of pulmonary artery involvement. Seven patients presented with short breath after exercise or hemoptysis as the first manifestation, four patients with fatigue, four patients with intermittent claudication or pain or numbness of extremities, three patients with dizziness. Seven patients belonged to type Ⅰ+Ⅳ, one patient to type Ⅱ+Ⅳ, three patients to type Ⅲ+Ⅳ, one patient to type Ⅴ. Elevated ESR/CRP was found in ten patients. All patients took the glucocorticoid and DMARDs, stent implantation in pulmonary artery was done in one patient, Bentall was operated in another patient.The symptoms of all patients improved except one patient died for low cardiac output after operation. Conclusion PAH is one of the severe complications in late stage of TA, and other arteries are usually involved too. Because it is difficult to observe PAH in TA patients in early stage, CTA or pulmonary angiography and UCG should be taken in early stage. The stent implantation or dilating the artery should be considered aa a treatment, but at on the same time, glucocorticoid and DMARDs should be taken to avoid the relapse.

Hedgehog signaling pathway is a conserved and important signaling pathway involved in proliferation and differentiation of many types of cells. Latest studies have found that Hedgehog signaling pathway may induce MSCs osteoblast differentiation by increasing the expression of the Runx2 and Osx and inhibit MSCs differentiate to adipocyte. Hedgehog signaling pathway may also promote osteoblast proliferation by regulating cyclin. This review summarizes the mechanism that Hedgehog signaling pathway regulates osteoblast differentiation and proliferation,and concludes that Hedgehog signaling pathway can regulate bone metabolism. It might provide new ideas for the treatment of osteoporosis.
