Guided by Professor Luo Yuankai and influenced by his academic thought, the gynecology department of the first hospital affiliated to Guangzhou University of TCM has made great achievements in the research of regulating menstruation, promoting gestation and calming fetus in recent 30 years. It is believed that based on the principle of kidney controlling the reproduction, kidney-tonifying therapy should be the principal method for the treatment of menstrual disease, pregnant disease and infertility which are characterized as deficiency syndrome.

Objective To study the effects of the early diagnosis and treatment of sleeve fractu re of patella in children.Methods The retrospection study was done to a nalyse the effects of the diagnosis a nd treatment of ten samples of sleeve fr acture of patella in our hospital fro m 1993to 2001.Results The diagnosis was confirmed by the characteristic s of the tension swelling of the knee,high position of the patella and a sle eve fractured fragment in the patella.T he operations were the main initial t reatment to regain the proper reduction.After 4weeksfixation the patients did knee exerc ises.And the curative effects were q uite good.Conclusion The sleeve fracture of the patella in children is easy to be misdiagnosed o r missed because of the cartilage.So it is the more important to be able to con duct an early diagnosis and treatmen t for the better prognosis.

OBJECTIVE To explore the drug resistance rate and risk factor of Pseudomonas aeruginosa against ceftazidime in a certain hospital,and provide scientific basis for preventing the P.aeruginosa infections.METHODS A total of 109 P.aeruginosa strains,which were isolated from sputum cultures in patients in a certain hospital in 2005,were identified with VITEK GNI+ automation system.The possible risk factors and underlying diseases were investigated by reviewing patients′ medical records.Multiple Logistic regression models were used for statistical analyses by SPSS software(13.0).RESULTS The resistant ratios against ceftazidime was 38.5%.P.aeruginosa resistant ratios in ICU and the neurosurgery ward were 78.57% and 54.84%,respectively,and higher than others.Treatment days before infection in hospital(over two days),staying at the ICU or neurosurgery ward,using breathing machine,were associated with the sensitivity to ceftazidime for P.aeruginosa.CONCLUSIONS In order to prevent and reduce the drug resistant ratios for P.aeruginosa,we should pay more attention to the patients admitted in ICU and neurosurgery wards.Risk factors,such as treatment days in hospital,living in different wards and using breathing machine,were associated with the resistant ratios for P.aeruginosa against ceftazidime.

Objective:To evaluate the changes in the transverse dimension and the perimeters of the maxillary archs produced by 3 self-ligating appliance systems during the leveling and aligning phases. Methods: 45 patients who had class I skeletal pattern and upper arch crowding 3-6 mm were divided into 3 groups with 15 subjects in every group. The dental casts were analyzed. Results: Statistically significant increases were recorded of all dentoalveolar widths (with the exception of intermolar width measured lingually) and arch perimeters. The increase in arch perimeter showed a significant negative relationship with the individual perimeter of the maxillary arch before treatment. No significant change was found in arch depth. Conclusion: The self-ligating appliance systems produce statistically significant increases in the transverse dentoalveolar width and the perimeter of the maxillary arch during the leveling and aligning phases of treatment.

Studies in recent years have demonstrated that stromal cell-derived factor-1 SDF-1/CXCR4 axis plays an important role in the process of angiogenesis. The expression of SDF-1 in ischemic tissue increases during cerebral ischemia. It binds to CXCR4 receptor on the surface of endothelial progenitor cells EPCs, and thus promotes bone marrow-derived EPC mobilization, proliferation, and migration to the ischemic areas and homing. EPCs differentiate into mature endothelial cells in the ischemic region, promote the formation of new blood vessels, and thus irrlprove the blood supply to ischemic tissue. This article reviews the effect of SDF-1/CXCR4 axis in the treatment of cerebral ischemia with EPCs.

Objective To discuss the effect of community prevention,therapy and rehabilitation for psychiatric patients undergoing "unlock program" and free from captivity. Methods We collected and compared the result for 71 pschiatric patients before and after free from captivity by the Brief Psychiatric Rating Scale(BPRS)and Global Assessment Scale(GAS)according to the work model of the psychiatric prevention,therapy and rehabilitation nursing program which complied with "socialization,comprehension and accessibility". Results After the unlock program the total score of BPRS and GAS greatly dropped to (22.57±3.13)and (80.67±15.57)respectively 2 years later,which were statistically different from those before the attendance of the unlock program (P＜0.01). Conclusions The unlock program proved to be a novel and effective nursing program for community prevention,therapy and rehabilitation of psychiatric patients free from captivity.

Objective To investigate the emotional distress and coping style during acute stage in patients following acute traumatic injury, and the relationship in different coping patterns and emotional distress. Methods A total of 118 patients with acute traumatic injury were included in our investigation.Emotional distress was assessed with the Hospital Anxiety and Depression scale. Coping style was measured with the Medical Modes Questionnaire. Descriptive analysis, independent samples t test and multiple linear regression analysis were used. Results Emotional distress occurred in 50.00% of the patients with acute traumatic injury,22.40% patients only presented anxiety, 17.30% patients only presented depression, and 10.20% patients presented both anxiety and depression. Yielding and avoidance coping styles were more frequently used in patients with depression. Conclusions Incidence of emotional distress was highly fre-quently, many factors were associated with patients" affection reaction.

Objective To observe the application effect of mental nursing on perioperative nursing of patients. Methods 66 patients with cutaneous carcinoma were randomly divided into the conventional nurs-ing group and the psychological intervention group. The conventional nursing group received perioperative mu-fine nursing,the psychological intervention group was given mental intervention before,during and after operation based on routine nursing. The anxiety value was measured before and 30 minutes after the operation, pain de-gree was assessed 30 minutes after the operation,the results underwent t test and X2 teat. Results Compared to the conventional nursing group, the anxiety value before the operation and 30 minutes pestoperation as well as pain degree 30 minutes pestoperation of the psychological intervention group were significantly decreased. Conclusions Mental nursing of patients with cutaneous carcinoma can efficiently eliminate or re-duco patients' psychologic obstacle and significantly reduce patients' painful feeling.

Long-term outcomes of surgical bile duct injury (BDI) repair are affected by multiple factors, such as surgeon's experience, severity of BDI, pathological changes of the proximal duct, and the manner and timing of surgical repair. However, the timing of BDI repair is still controversial still. In this article, the authors reviewed the correlation of pathophysiologic changes of the proximal duct, repair timing and outcome discussed in English references. It was shown that pathophysiologic changes of the proximal duct are a major contributor to the timing of BDI repair.
