Recently imageless navigation systems have been developed rapidly, and have become major navigation system in clinic. It comprises computer workstation, infrared optical localizing system, foot control pedal and navigation software. Currently, imageless navigation systems have been used successfully in total knee arthroplasty, uni-compartment arthroplasty, total hip arthroplasty, hip surfacing arthroplasty, total shoulder arthroplasty, anterior cruciate ligament reconstruction and peri-articular osteotomy of knee, etc. The first OrthoPilot imageless navigation system was used by Saragaglia et al in total knee arthroplasty in January 1997, and many clinical studies have been conducted. The clinical results show that this kind of systems greatly improves operative accuracy, and reduce cases beyond ideal range. It shows accuracy as CT-based navigation systems, and they can be commonly used as standard navigation systems in clinic.

The purpose of this work was to reestablish the respiratory abduction of the paralyzed vocal cord through reinnervation of the posterior cricoarytenoid (PCA) muscle by partial phrenic fibres.In fifteen adult cats the adductor branch of the recurrent laryngeal nerve (RLN) of the right side was cut and its distal end ligated, while its proximal end was implanted into the PCA muscle belly.The whole RLN was then transected in the tracheo-esophageal groove and its distal stump anastomosed to the upper branch of the phrenic nerve.Direct laryngoscopy showed that the inspiratory abduction of the paralyzed vocal cord recovered within 40 d in all cats.80 d later, a larger abducent motion of the glottis was observed on the reinnervated side.Abduction was caused by reinnervation of the PCA muscle from phrenic motoneurons, as demonstrated by laryngeal electromyography and histological testings.The function of the diaphragm was preserved as revealed by monitoring of the intrathoracic pressure.

Objective To observe the clinical effect of interferon -1 b (Yundesu)in the treatment of verru-ca planae.Methods 1 1 0 patients with verruca pianae were randomly divided into observation group and control group,55 cases in each group.The observation group was given Yundesu injection 30 g once every day in first week, and once every other day in another three weeks.The control group was given orally mannatide 1 0ml two times every day.The leision changes of the two groups were observed after 4 weeks therapy.Results The total effective rate of the observation group was 92.7%(51 /55),which of the control group was 72.78%(40 /55),the difference between the two groups was statistically significant (χ2 =7.70,P <0.01 ).No adverse reactions in the two groups were observed.Conclusion The clinical effect of Yundesu is more prominently beneficial to patients with verruca planae.

Early diagnosis of inflammation and properly interfere to improve the prognosis are very important.However,it is difficult to verify inflammation or differentiate inflammation from infection in clinic,especially in the condition of underlying inflammation.Currently,radiopharmaceuticals based on researches of pathophysiology progress of diseases are studied constantly.This review summarizes the potential inflammation imaging radiotracers and their mechanisms,potential clinical application value.

Objective To explore the compound azintamide + mosapride application regimen in elderly patients with gastrointestinal diseases and associated dyspepsia in the treatment. Methods 116 cases of elderly patients with gastrointestinal disease associated dyspepsia patients treated in our hospital from April 2016 to April 2017 were randomly divided into observation group and control group, with 58 cases in each group. The observation group was treated with azintamide + mosapride,the control group was treated with mosapride,the two groups were treated for 28 d .The total score of dyspeptic symptoms before and after treatment in two groups was recorded, and the clinical symptoms were evaluated according to the remission rate of symptom scores. The incidence of adverse reactions in the two groups was calculated and compared between the two groups. Results There was no significant difference in total scores of dyspepsia symptoms between two groups before treatment. The total score of the two groups of dyspepsia symptoms decreased in different degrees after the end of the effective course,the observation group was significantly better than the control group (P<0.05). The effective rate of the observation group was 87.9%, which was significantly higher than that of the control group (60.3%) (P<0.05). Conclusion Compound azintamide combined with Mosapride is effective in the treatment of gastrointestinal diseases associated dyspepsia in elderly patients, combination therapy significantly improved in patients with dyspeptic symptoms, improve the quality of life of patients, clinical application of feedback is good, safe and reliable.

Objective To observe the effect of treating diabetic peripheral neuropathy(DPN) with methylcobalamin and Chinese medicines with the funetious of nourishing Yin and promoting blood circulation. Methods 72 patients with DPN were randomly recruited into a control group and a treatment group.Symptoms, NCV,value of blood routine examination,blood biochemistry check and ECG were compared before and after the treatment. Results The total effective rate was 88.0% and 68.2% in the treatment group and the control group respectively,showing significant difference (t=3.14, P<0.01).The value of blood routine examination, blood biochemistry check (except blood sugar level) and ECG showed no obvious changes before and after the treatment in both groups.Conclusion Therapy of methylcobalamin Tablets with Chinese medicines of nourishing Yin and promoting blood circulation is effective on DPN and worth of clinical promotion.

Objective To observe the effect of treating DPN with xuesaitong tablet and mecobalamine. Methods 112 patients with DPN were randomly recruited into a treatment group (60 cases) and a control group (52 cases). The control group was treated with mecobalamine, 0.5 mg. Rid., while the treatment group was treated with Xuesaitong tablet, 50mg tid.,On the basis of the control group. Both groups were treated for successive three months. Results The total effective rate was 78.33% and 57.70% in the treatment group and the control group respectively, showing a statistical difference (t= 1.9804, P=0.0271). Conclusion The combined therapy of xuesaitong tablet and mecobalamine was more effective on DPN than mecobalamine used only.
