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.

The barrier function is an important characteristic of the gut and an important determinant in the outcome of critically ill patients. Its workings are complex and it consists of epithelial, molecular, and immune components. The pathogenesis of gut dysfunction among critically ill patients is multifactorial. The purpose of this literature review is to provide a better understanding of the normal defense mechanisms of the gut, alterations associated with ischemia reperfusion injury, risk of infection, starvation and malnutrition and severe trauma, and potential therapies for gut dysfunction in critically ill patients.

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.

Objective To investigate the correlation between the serum levels of homocysteine (Hcy) ,folate acid (FA) and vita‐min B12 (VitB12 ) with cerebral infarction .Methods The enzymatic cycling method and chemiluminescence immunoassay were used to detect the serum Hcy ,FA and Vit B12 levels in 60 patients with cerebral infarction ,and then the detection results were compared the results of 40 people undergoing physical examination in the same period .Results The serum Hcy level in the cerebral infarction group was (23 .16 ± 8 .17)μmol/L ,which was significantly higher than (8 .09 ± 2 .45)μmol/L in the control group(P<0 .01) ,and the serum FA and Vit B12 levels in the cerebral infarction group were (6 .12 ± 2 .19) ng/mL and (323 .92 ± 133 .79)μmol/L ,which were in the control group lower than (10 .57 ± 5 .70) ng/mL and (530 .85 ± 168 .56)μmol/L in the control group (P<0 .01) .The serum Hcy level in the cerebral infarction group showed the negative correlation with FA and VitB 12 levels ( r1 = - 0 .444 , r2 = -0 .535 ,P<0 .05) .Conclusion High hyperhomocysteinemia is an independent risk factor of cerebral infarction and is related to the decrease of FA and VitB12 .
