Objective To observe the clinical effect of ilaprazole in the treatment of peptic ulcer.Methods 100 patients with peptic ulcer were randomly divided into omeprazole group and ilaprazole group,50 cases in each group.The patients were given omeprazole or ilaprazole combined with amoxicillin and clarithromycin.The treatment effects and clinical symptom relief satisfaction rate were compared between the two groups.Results After treatment,the results under gastroscopy:in ilaprazole group,20 cases cured,16 cases healed,9 cases were effective and 5 cases were invalid.Those in omeprazole group were 14 cases,12 cases,12 cases,12 cases respectively.The differences between the two groups were statistically significant(U =3.78,P ＜ 0.05).The removal rate of Helicobacter pylori and clinical symptom relief satisfaction rate of ilaprazole group were significantly higher than those of the omeprazole group(x2 =3.84,4.57,P ＜ 0.05).Conclusion Ilaprazole can obtain good clinical effect in treatment of peptic ulcer,with high symptom relief satisfaction rate and clearance of Helicobacter pylori.

As a major breakthrough in biomedical field, mRNA vaccine technology has broad application prospects in the prevention and treatment of infectious diseases and tumor treatment. However, mRNA vaccines are a patent-intensive industry, and related core technology patents are mainly controlled by foreign companies. By analyzing the global patent application situation of key technology branches of mRNA vaccines and the differences between domestic and foreign enterprises' products and technology platforms, this paper constructs a patent barrier index model covering patent layout density and claim intensity, and systematically combs the technology competition pattern combined with patent dispute cases of leading enterprises, in order to provide ideas for domestic enterprises to break through patent barriers, optimize research and development paths and risk prevention and control strategies.

With the rapid development of neurosurgery,requirement for neuroanatomy is increasing in clinical practice.The authors made a primary exploration on how to teach focal neuroanatomy for neurosurgical postgraduate students.The idea of asking the students to draw focal anatomy was suggested by the author with the purpose of making them learn it positively.Software workstation and clinical neuroradiological work-ups such as MRI and DSA were also applied and evaluated.The authors proposed all these procedures be helpful for comprehending neuroanatomy.

Objective To investigate the effect of Lokomat gait training rehabilitation robot on joint motion and lower limb function in hemiplegic patients after stroke.Methods Forty hemiplegic patients after stroke were randomized equally into a robotic group and a control group (20 cases in each group).The robotic group received robotic rehabilitation therapy in addition to routine rehabilitation training,while the control group was only given instructions for routine rehabilitation training.All the patients were assessed at the beginning of the training and at the end of 4,8 and 10 weeks of treatment.The Fugl-Meyer Assessment of lower extremities (FMA),range of motion (ROM) in hip and knee,force and tone of bilateral hip/knee flexors and extensors were used to evaluate stepping function before training,and after 4,8 and 10 weeks of treatment.Results There was no significant difference between the 2 groups with regard to FMA scores,the ROM in hip and knee,as well as force and tone of bilateral hip/ knee flexors and extensors (P ＞ 0.05).After treatment,the robotic group was significantly improved with all the evaluation indexes when compared to its baseline values (P ＜ 0.05).It was also shown that the robotic group improved to a significantly greater extent than the control group (P ＜ 0.05).Pearson's correlation analysis demonstrated a positive relationship between the ROM of knee or hip and lower limb function (P ＜ 0.05).Conclusions The Lokomat gait training rehabilitation robot can improve the lower extremities functions,as indicated by increase of ROM and muscle strength as well as decrease in muscle spasticity in hemiplegic patients after stroke.

Objective To study the influence factors on the enflurane uptake in child with congenital heart disease(CHD).Methods Sixty children aging less than 5 years with CHD were randomly divided into four groups: in group A 15 children with atrial septal defect(ASD)or ventricular septal defect (VSD) inhaled enflurane before and after CPB;in groups B 15 children with ASD or VSD did only after CPB,in group C 15 children with tetralogy of fallot (F4) did before and after CPB;in group D 15 children with F4 did only after CPB.The concentration of enflurane (F I) was kept at 0.5%.Following inhalation of enflurane,the end tidal alveolar concentration (F E) was measured in 30 min and the time of uptake equilibrium (Tue,F E/F I=1) was recordcd.Results In group C,Tue before CPB was shorter than that before CPB and after CPB in group A,that in group B and group D (P

Objective To study the X-ray and CT findings of pneumocystis carinii pneumonia(PCP)in AIDS.Methods 18 cases with PCP in AIDS proved by clinic and pathologically were collected.HIV antibody was positive in all cases.Chest radigraphy and CT scan were taken in all cases.The imaging findings were analysed.Results The typical features of PCP on radiography and CT included unsymmetric diffuse mesh or reticulo-nodular changes,symmetric ground-glass opacification and many more even lobar consolidations which distributed in bilateral hilar regions and middle-lower lung fields.The atypical manifestations included cystic lesions,lobar consolidation,hilar and/or mediastinal adenopathy,pleural effusion,pneumothorax,atelectasis,mass and cavity-mass.Conclusion Plain chest film and CT scan are of important value in diagnosis of PCP.It is possible to diagnose PCP in patients with typical imaging manifestations positive HIV and in combination with clinical data.

[Objective]To explore the dependability between heredity and hallux valgus.[Method]A total(1 491) cases of family heredity of hallux valgus patients were investigated,the ages of these patients,ages of onset,ages of aggravation,hallux valgus angles were analyzed statistically.[Result]Conclusive family medical history exists in 69.48% of the(1 491) hallux valgus patients.There was distinguished difference between the patients with family history and those without heredity background on visiting ages,ages of onset,ages of aggravation;but no any difference between these two groups of patients on hallux valgus angles.[Conclusion]Heredity factor is the main cause of hallux valgus.It can influence only the onset of hallux valgus,but not the severe degree of latter.The patients with family history are earlier than those without heredity background about visiting ages,ages of onset,ages of aggravation.

Objective To investigate the indication, preoperative evaluation, technical tip, prevention and treatment of complications, effect, and clinical use of the embolization of intracranial aneurysms by using GDCs. Methods From July 1998 to February 2000,93 patients with 118 intracranial aneurysms were embolized using GDCs, including 84 ruptured aneurysms (Hunt-Hess grade, Ⅰ 18 cases, Ⅱ 29 cases, Ⅲ 25 cases, Ⅳ 10 cases, Ⅴ 2 cases). 72 patients were treated at emergency, and 48 patients had CTA examination preoperatively. The operations were completed under the DSA monitoring. Continuous lumbar subarachnoid drainage was instituted and standard 3H treatment was given postoperatively. Results Total occlusion was achieved in 104 aneurysms(88 14%), over 90% in 11aneurysms(9.32%), less than 90% in 3 aneurysms(2 54%), with 3 patients (3/93, 3 23%) died in the cohort. One case rebleeded after 1.5 months and was cured by surgical clipping, 2 patients experienced enlargement of the aneurysmal neck and were reembolized. Following-up was performed from 2 to 22 months, 1 had severe disability, 7 had mild neurological deficit symptoms. Conclusion The results of short-term follow-up suggested that embolization of intracranial aneurysms with GDCs be microtraumatic, safe, effective, and reliable. Partial packing may result in continuous enlargement, rupture, and bleeding, while tight coil packing in aneurysms was reliable. The ruptured aneurysms need emergency embolization, and postoperative continuous lumbar subarachnoid drainage can enhance curative effect significantly.
