Objectives:We investigated and studied the incidence of depression in the wake of cerebral infarction Methods:Self-rating Depression Scale (SDS) and Hamilton Depression Scale (HAND) were evaluated and tested among 210 patients of cerebral infarction, and at the same time a contrast was made among 50 normal persons At the patients were divided into two groups, one suffered from depression and the other not suffered from depression Then they were compared Results:The depressive mood of the patients of cerebral infarction was obviously higher than those of normal group In this thesis, the incidence of cerebral infarction with depression is 58% The incidence of this disease was higher among the patients with depression history, females and those who lived apart from one's family Conclusions:The incidence of cerebral infarction with depression is comparatively high, so it should be taken seriously by the clinical doctors

OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:By retrospective survey meth-od,the drug utilization of IVF outpatient department in our hospital during Jun. 2012-May 2014 were analyzed statistically in re-spects of consumption structure,consumption sum and DDDs,etc. RESULTS:Oral medicine was major type of medicines in IVF outpatient department,followed by injection;total consumption sum was on the rise,and the sum of injection accounted for large proportion. Ovulation stimulants and sex hormone class medicine,vitamin and other nutritional drugs were main drugs used in IVF outpatient department. The consumption sum and DDDs showed obvious asynchronism. CONCLUSIONS:The drug use is reason-able on the whole. But expensive ovulation stimulants increase the economic burden of patients to some extent.

Objective To evaluate the serum histamine-releasing activity of patients with chronic urticaria and explore the pathogenesis of chronic urticaria. Methods Sixty-two chronic urticaria patients were studied by using in vivo autologous serum skin test (ASST) and in vitro histamine release assay of human cutaneous mast cells incubated with the patient′s sera. Results Twenty-four out of 62 patients showed a wheal response to autologous serum (38.71%). Sera from patients with chronic urticaria released a significantly higher quantity of histamine compared with the control subjects (P

BACKGROUND:Endovascular embolization materials have been produced and used clinicaly, but new problems constantly occur in the clinical application and new demands are also developed for embolic materials. OBJECTIVE:To retrospectively analyze the advantages and disadvantages of various types of embolic materials and to investigate the relationship between application fields and selection of embolic materials, thereby providing a reference for clinical treatment. METHODS:CNKI and PubMed databases were retrieved for relevant literature, and then embolic materials were systemicaly reviewed based on relevant clinical application and basic research literature in the folowing aspects: embolism mechanisms, clinical applications, advantages and disadvantages of various embolic materials. In this review, the existing problems in the current study were pointed out, and the development direction of relevant research and clinical application were also prospected. RESULTS AND CONCLUSION:Embolic materials should have biodegradability and biocompatibility. Current embolic materials include absorbable gelatin sponge, Polyvinylalcohol embolic agent, micro-coils and liquid embolic materials. Gelatin embolic material has no antigenicity and good histocompatibility, as wel as has excelent compressibility and water re-expansibility. Polyvinylalcohol particles are a polymer material that is insoluble in water, has high expansion coefficient, mechanical embolization, non-alergenic reaction, no acute systemic toxicity, no intracutaneous irritation, and can be used safely and effectively. Adhesive liquid embolic material has no vascular toxicity and has been widely used. Endovascular embolization materials have been produced in succession, and meanwhile, new problems in clinical applications have been found and new demands for embolic materials have been put forward continuously. Thus, a variety of embolic materials have their own advantages and disadvantages, and none of embolic materials can be applied to al diseases. To select an appropriate embolic material is very important for safe and effective treatment.

BACKGROUND:Bone defects often occur after the reduction of periarticuar fractures, and bone grafting is required to fil bone defects, thereby to make the early support of articular surface and prevent the col apse and shift of the articular surface. Al ograft cancellous bone is the transplant material for the treatment of bone defects, but its osteogenesis ability is poor. Autologous red marrow has osteogenesis ability. Therapeutic efficiency of al ograft cancellous bone combined with autologous red marrow for periarticular fractures is stil yet to be
assessed.
OBJECTIVE:To study clinical effect of locking plate fixation and al ograft cancellous bone combined with autologous red marrow in the treatment of periarticular fractures.
METHODS:Forty-three cases of periarticular fractures were incorporated into the Orthopaedics Department of the Third Hospital of Hebei Medical University. After cutting the articular surface anatomical y, composite particles of the red marrow and al ograft cancellous bone were implanted into bone defects, and then, an anatomic locking plate was used. Medial lateral or bilateral locking plate was used for tibial plateau fractures. Dorsal or volar locking plate was used for distal radius fractures, and distal tibial medial or lateral locking plate was used for distal tibial fractures.
RESULTS AND CONCLUSION:Forty-three patients were fol owed up for 12 months to 6 years, an average of 4.3 years. X-ray films and CT scans review showed that 43 patients’ col apse fracture al reached bony union. Fresh fracture healing time was 2-6 months, an average of 4 months;the healing time for old fracture was 3-7 months, an average of 5.5 months. After bone grafting, 43 patients al had no significant immune rejection, two cases showed more wound exudates, and the wound was healed by dressing after 2 weeks. One case had wound infection, the wound was healed after 4 weeks of draining and dressing, and the infection had no recurrence fol owing up for 4 years and 1 month. Forty patients were satisfied with bone grafting, accounting for 93%, and three cases dissatisfied, accounting for 7%, based on Mankin and Komender’s standard assessment. The results confirmed that al ograft cancellous bone combined with autologous red marrow transplantation can play a supporting role in treating periarticular fractures to prevent the col apse of the articular surface and fracture displacement, and to provide reconstruction materials for periarticular defects. Its long-term goal is fracture healing.

Human IL-6,IL-10,IL-13 and SCF cDNAs encoding extra - cellular domain were isolated by reverse transcription polymerase reaction (RT-PCR). These cDNA fragments were inserted into expression vector PBV220 which contains PRP_(L), promoters and SD sequence. Then the E. coli DH5? were tronsformed with the recombinant plasmids. After screening, the clones carrying those recombinant plasmids were identified. SDS-PAEG and biological assay indicated that human IL-6, IL-10 and IL-13 were expressed in E.coli. The expression level of rhIL-6 was as high as 30% of the total bacterial protein.

Objective To explore the diagnosis and treatment of anatomic variation of the extrahepatic biliary tree in laparoscopic cholecystectomy(LC).Methods From October 1999 to January 2008,totally 1216 cases of LC were performed in our hospital,anatomic variation of the extrahepatic biliary tree was found in 15(1.2%) of them.Among the 15 patients,3 had wide and short cystic duct with the opening at the junction of the right and left hepatic ducts;1 patient showed dislocation of a relatively thin choledoch owing to calculus incarceration;1 case was found having a cystic duct parallel to the common hepatic duct with a low-level opening;1 patient had twisted cystic duct at the right side of the common bile duct with an opening at the right hepatic duct;2 patients were suffered from massive adhesion in the cystic ampulla that covering the common bile and common hepatic ducts;3 cases showed aberrant bile ducts lying on the gallbladder bed;3 patients were found having the right posterior hepatic duct opened to the common hepatic duct;1 case was diagnosed with Mirizzi syndrome,in whom the anatomical structure was unclear.For all of the patients,the abnormal structures were separated carefully,ligated with sutures or titanium clips if necessary.Results LC was completed in 13 of the 15 cases,the other 2 patients were converted to open surgery because of the injury to the right hepatic duct or Mirizzi syndrome.None of the series had intra-abdominal bleeding or infection,bowel injury,or death.The patients were followed up for 3 months to 4 years(over 1 year in 11 cases).None of them developed biliary stenosis or residual calculus.Conclusion Identification of the Calot triangle is crucial to prevent surgical injuries to the extrahepatic biliary tree.
