The doctor-patient relationship is always the focus in the society. The relationship seems more complex and sensitive in the pediatric surgical ward because its patients are kids. However, the pediatric surgical residents' ability of doctor-patient communication is lack of systemic and norma-tive training, which is not good for the mutual understanding between doctors and patients. This study explores how to enhance the residents' doctor-patient communication skills from the perspective of awareness, professional knowledge and some specific skills. In the meantime, it discusses the need to train the teachers and set up a regular examination-assessment system.

Abstract BACKGROUND: Recently, microcarrier culture as a high concentration cel culture technology has been used in hepatocyte culturein vitro. OBJECTIVE:To periodicaly observe the morphological changes of human hepatocyte L-02 cultured by the spherical porous chitosan microcarrier. METHODS:The self-made spherical porous chitosan microcarrier sample as a support to culture human hepatocytes L-02 acted as experimental group; non-spherical porous chitosan microcarrier as a support to culture human hepatocytes L-02 as control group. Cels in two groups underwent cel count at regular time, and the morphological changes were observed in the experimental group, including inverted phase contrast biological microscope observation and scanning electron microscope observation. RESULTS AND CONCLUSION:The quantity of cultured cels in the two groups was increased in the first 3 days and reached the peak at the 3rd day. The cel quantity in the experiment group was obviously higher than that in the control group (P < 0.05). There was no significant difference in the three samples of the experimental group (P > 0.05). The quantity of hepatocytes adhered to the microcarrier surface was gradualy increased in the former 3 days under the inverted phase contrast biological microscope. There were lots of cel clusters on the surface of a greater part of microcarriers, with the total survival rate of more than 90%, and hepatocytes kept a good morphological structure. Under the scanning electron microscope, lots of hepatocytes adhered tightly to each other on the surface and section of microcarrier as wel as inside the microcarrier. It is indicated that the self-made spherical porous chitosan microcarrier as a support in three-dimensional environment can undergo cel culture with high concentration.

Objective To study the efficacy of simple Chinese medicine steam spray and comprehensive rehabilitation nursing after facial burn deep Ⅱ degree.Methods 80 patients were randomized into the treatment group (40 cases) and the control group (40 cases).The treatment group was given the treatment of Chinese medicine steam spray.The control group was given the treatment of Chinese medicine steam spray,pressure therapy,physical therapy,rehabilitation training and psychotherapy.The clinical efficacy of two groups was evaluated respectively after 3 months.Results After 3 months,the skins of most of patients in the treatment group were nearly normal with no pigmentation and scar hyperplasia.The cure rate was 72.5 ％,the obvious effective rate was 12.5 ％,and the effective rate was 7.5 ％.Some patients in the control group were lightly and inconspicuously pigmented,but the pigmentation area was reduced.The colour of their skins was not different from that of the normal skin.The cure rate was 42.5 ％,the obvious effective rate was 12.5 ％,and the effective rate was 25.0 ％.The effects of the two groups were significant differences (P＜0.05).Conclusions Comprehensive rehabilitation nursing after the facial burn can reduce the pigmentation and scar hyperplasia and improve the quality of life.

Objective:To investigate the protection of acupuncture on damaged myelin sheath from the poinr of view of neurological functional recovery and morphological changes of the myelin sheath.Methods:Eighty-nine adult male Sprague-Dawley rats were randomly allocated to normal (n=5),sham-operation (n=21),model (n=21),early acupuncture (n=21) and late acupancture (n=21) groups.A model of middle cerebral artery occlusion was induced by the intraluminal filament method.Acupuncture was performed at different time points after ischemia.Neurological function and morphological changes of the myelin sheath of ischemic focus were observed by using the methods of neurological deficit scores and Pal-Weigert's myelin staining.Results:Neurological deficit scores at 2.5 hours after the procedure in the model group increased significantly (P＜0.05).qhe scores decreased somewhat as the time elapsed.The internal capsule had obvious demyelination and recovered slowly.Neurological deficit scores in rats at each time point decreased faster in the acupuncture group compared with the model group,and they decreased significantly at day 3 (P＜0.05);the extent of demyelination was significantly alleviated.Neurological deficit scores decreased faster in the early acupuncture group compared with the late acupuncture group (P＜0.05);and demyelination in the early acupuncture group seemed milder at day one.Conclusions:Early acupuncture is beneficial to remyelination and neurological functional recovery after cerebral ischemia.

Objective Evaluation of imatinib mesylate treatment of unresectable/marginally resectable gastric and duodenal stromal tumors,as well as its side effect and the toxicity.Methods Oral imatinib mesylate was prescribed at the dose of 400 mg/d for 12 cases of patients with unresectable/marginally resectable gastric and duodenal stromal tumors.The evaluation of the adverse reactions was in accordance with United States NCI-CTC grading standards (3rd edition).Choi standard was used to evaluate the patients at 3 and 6 month time points.Results For hematological toxicity,only 1 case of patient with Ⅲ° decreased white blood cell count,and the rest patients were with Ⅰ° to Ⅱ ° degree.For nou-hematological toxicity,the author observed cardiac toxicity,liver function damage,renal function damage,diarrhea,abdominal pain,nausea/vomiting,fatigue,anorexia,muscle pain,rash,hair loss,skin and mucosa edema.Among them,there was only 1 patient with Ⅲ° skin rash,and 1 patient with Ⅲ° edema,all the rest were with Ⅰ° to Ⅱ °.Eight and 11 cases of patients were evaluated as partial remission (PR) after 3 and 9 months of treatment respectively.Among them,nine patients were given R0 resection and 2 patients denied surgery due to old ages.One patient was stable (SD).Conclusions Preoperative treatment of patients with unresectable/marginally resectable gastrointestinal stromal tumors by imatinib mesylate will increase the resection rate.The related toxicity can be well-tolerated.

A kind of skin cell segregating unit based on 80C196 microcomputer is presented in this paper. The front-end controller is a single-chip microcomputer. The unit enables manipulation for 6 patients simultaneously which provides a great convenience for clinical manipulation of vitiligo. With use of serial port communication technology it's possible to monitor and control the front-end controller in a PC terminal. The involvement of computer image acquisition technology realizes synchronous acquisition of pathologic skin cell before/after the manipulation. Clinical test of the unit proves its conformity with national standards and fulfillment of designed technology goal.

Objective To observe clinical effect of treating chronic obstructive pulmonary disease(COPD) in exacerbation stage with aerosol inhalation of budesonide combined with Chinese herbal enema. Methods 36 cases with COPD were randomly recurited into a control group and a treatment group. The control group was treated with routine western medicine, and the treatment group was treated with aerosol inhalation of budesonide combined with Chinese herbal enema. The clinical effect was observed in both groups, Results The total effective rate in the treatment group and the control group was 88.9% and 72.2%, respectively, showing significant difference between the two group. (P<0.05) .Conclusion The treatment of aerosol inhalation of budesonide combined with Chinese herbal enema on COPD is better than routine western medicine.

Subcutaneous insulin resistance is a condition in which glucose is insensitive to insulin from the subcutaneous tissue,but sensitive to that by intravenous injection.The mechanism of subcutaneous insulin resistance is mainly associated with skin obstruction or delayed entry of insulin into blood circulation.The treatment of the problem involves Aprotinin,anticoagulant and intramuscular injection of insulin.This paper offers an overview of the advances in the researches of subcutaneous insulin resistance.
