Artificial hip replacement is an effective therapy to eliminate hip pain,correct deformity and restore function.With population aging and improving of people life quality,artificial hip replacement has been widely conducted.Over the past 40 years,artificial hip replacement technique has rapidly developed,and minimally invasive technology presents development direction of future artificial hip replacement.Skilled operation experience and instrument application are two key factors to ensure surgery success.The minimally invasive technology arouses more attention from clinical doctors and patients due to minimal invasion,little blood loss and fast recovery.However,not all patients can undergo minimally invasive hip replacement.This paper summarized related studies on minimally invasive hip replacement in domestic,and discussed the indications,surgical approach,complications and prevention.

This paper introduces general guidelines for designing and constructing a magnetic stimulator (MS). These guidelines cover the theoretical concepts, hardware aspects and necessary components. RLC model producing the impulses in MS is focused on and the way to calculate the parameters of the model is presented. Some factors that influence induced magnetic field are discussed. Experiments are carried through with self-developed round coil and 8-shaped, and Tesla meter is used to detect the magnetic fields. The experiments data show that the distribution of the induced magnetic fields by the two coils are tailored to those of theoretical calculation adopted now. A simulation experiment to measure magnetic field in brain has been completed.

This paper introduces primarily the design of hardware and software systems in infrared automatic handwash basin including the working process of the electric circuit. At the same time, in order not to act mistakenly suffering from exterior interference, the anti-interference function is added to the software, which is also the design technique of this software.

Objective:To study the clinical value of susceptibility weighted imaging(SWI)in brain diseases.Methods:37 cases with blood vessel pathological change of brain diseases were collected and analyzed,including 8 example of angioma cavernosum,10 cerebral infarction,15 brain tumor,2 venous malformation and 2 venous sinus thrombus.Conventional T1WI,T2WI,DWI,the SWI and enhanced T1WI,MRA images were performed to compare the superiority of the SWI images to the others in demonstrating the small hemorrhagic focuses,the small vein,hemosiderin,calcification and other paramagnetic materials.Results:SWI could distinguish the hemorrhage from the blood vessel and discover the smaller hemorrhagic focuses of the angioma cavernosum.It could discover more tiny veins adjacent to the dilated draining vein.SWI could detect small hemorrhages in acute cerebral infarction and small draining veins in brain tumor.And draining veins in deep part and expanded rete venosum in the surfaces of brains could be obviously demonstrated when sinus venosus thrombus occurred.Conclusion:SWI is a new pulse sequence that can demonstrate the abnormal low current capacity blood vessels,the structure of small vein,the tiny hemorrhages as well as ferrugination and calcium deposition sensitively.So it can be applied in the diagnosis and antidiastole of the central nervous system diseases as an important supplement to the MRI conventional sequences.

Objective To investigate the clinical efficacy of cobamamide combined with Longxuejie in the treatment of herpes zoster in the elderly .Methods 104 elderly patients with herpes zoster were randomly divided into the treatment group and the control group .Both the two groups were given orally famciclovir 250mg,3 times a day for 14 days,intramuscularly injected gland glycosides cobalamin 500mg,1 day,14 days a course of treatment ,the treat-ment group was given Longxuejie enteric-coated tablets 4,3 times a day orally for 14 days.The blisters disappeared , pain relief,and recovery time of completely crusted ,treatment efficacy and neuralgia were compared between the two groups.Results In the treatment group,34 cases were cured,effective in 13 cases,total effective rate was 90.4%, which was significantly higher than 73.1% in the control group,the difference was statistically significant (χ2 =5.216,P<0.05).The blisters disappeared,pain relief,and recovery time of completely crusted in the treatment group were significantly shorter than those in the control group (t =3.216,5.432,4.643,3.654,all P <0.05).No postherpetic neuralgia was observed in the treatment group ,the incidence rate of postherpetic neuralgia of the control group was 13.5%,the difference was statistically significant (χ2 =4.875,P<0.05).Conclusion The Longxuejie combined with cobamamide in the treatment of herpes zoster in elderly patients has reliable effect ,fast improvement of clinical symptoms,a low incidence of postherpetic neuralgia ,it is worthy of clinical application .

10 kinds of normal and immunodifi-cient mice were used and they were found to have different levels ofNK activity.The NK activity toHuman to Human,Human to Mouseand Mouse to Mouse hybridomacells was much lower thanthat to YAC-1 cells in all mice andthere were no significant differencesbetween the two kinds of human Bcell hybridomas in susceptibility toNK cells.The results showed thatNK cells had no obvious effects onxenografts of human B cell hybri-domas.

The red blood cell sorbitol levels of 23 healthy subjects and 66 diabetic patients were measured enzymatically. Results showed that erythrocyte sorbitol levels of both IDDM (17) and NIDDM (38) patients with poor control were significantly higher than that of the controls and positively correlated with the coincident plasma glucose concentration, 24-hour urinary glucose excretion and HbA1c. There was no significant difference between the red cell sorbitol concentration of NIDDM with normal blood glucose level and that of the normal group; moreover, red cell sorbitol levels did not sig-nificantly correlated with FBG in both groups. Although there was no significant difference between the FBG of poorly controlled IDDM and NIDDM groups, red blood cell sorbitol levels were significantly different in both groups. This suggested that red blood cell sorbitol level could be used as an indicator of diabetic control.

The present paper is an analysis of the pattern reversal visual evoked potentials (P-VEP) of macular disease (40 cases, 57 eyes), in contrast to normal persons (40 cases, 80 eyes) of similar age. The group consists of 9 different kinds of disease-central serous chorioretinopathy macular hemorrhage, macular dege-neration, etc. The authors analyzed the latency and amplitude of P-VEP in different macular disease with different course and central vision. The results showed that the latency of P-VEP in the group was relatively prolonged. In contrast to normal person P 100 was prolonged by 9.0, 26, 40 ms at 1?2′, 30′, 16′ visual angles respectively. The amplitude was obviously lowered, especially at the visual angle of 16′ and P-VEP extinguished in all the eases with visual acuity less than 0.1.The latency and the amp-litude were not related to the type and the course of the maeular disease, but were closely related to the central vision.

Objective To study the effect of acid burn on rat corneal endothelial damage and its repair.Methods The model of mild,moderate and severe acid burn in cornea was established in 90 Long-Evans rats(n=30 for each degree of acid burn) with 4 rats served as normal controls.Corneal edema,opacity and the healing of epithelium were observed with a slit lamp microscope.The corneal endothelium from half rats of each degree acid burn was stained with trypan blue and alizarin red,and that from the other half with hematoxylin and eosin(HE) immediately,30 min,1,3,7,14,21,28 d after cautery.The endothelial damage and its repair were observed and the number of the leucocytes in cornea was calculated under light microscope.Results No damage was seen in the corneal endothelial cells of mild,moderate acid burn,only a few leucocytes could be seen in the cornea,and the healing of epithelium,the regression of edema were within 7 d.The endothelial cells necrosed and shedded in the wound area by severe acid burn.The endothelial cells in the margin were deformed,elongated and slided to the damaged area during repair,and a great number of leucocytes infiltrated,the healing of corneal epithelium was delayed,the regression of edema was up to 28 d.Conclusion The corneal endothelial cells were damaged in severe acid burn.The secondary inflammatory reaction took part in the damage of corneal endothelial cells after severe acid burn.The damage of endothelial cells delayed the healing of corneal ulcer and edema.
