Objective To investigate clinical effects of neoadjuvant chemotherapy of TAC scheme in breast cancer.Methods 82 patients with locally advanced breast cancer receiving neoadjuvant TAC chemotherapy program were retrospectively analyzed.The total efficiency,toxicity,and recent surgical cases were evaluated.Results There were 21 cases of CR in 82 cases with breast cancer,accounting for 25.6％,47 PR(57.3 ％),14 SD(17.1％),so the clinical total effective rate was 82.9％.The major toxic reactions was bone marrow suppression and neutropenia occurrence rate was 81.7％.Other adverse effects include gastrointestinal symptoms and liver dysfunction,and alopecia.All patients after symptomatic treatment can be tolerated.Conclusion TAC program neoadjuvant chemotherapy for locally advanced breast cancer patients can improve the cure rate,increase breast-conserving opportunities.

Objective To observe the subarachnoid space the epidural space joint block labor analgesia (CSEA) changes of T lymphocyte subsets.Methods 100 cases of full-term mothers were randomly divided into two groups,analgesia group and the control group.The analgesic group row CSEA childbirth analgesia.Two groups of maternal cervix large 2 to 3cm (T1),when the baby was delivered (T2),24h (T3),blood was colleoted after childbirth,detected by radioimmunoassay of cortisol.Flow cytometry assay was wsed to test T lymphocyte subsets CD3+,CD4+,CD8+,CD4+/CD8+,And the birth process,Apgar score,Labor pain visual analogue score (VAS) were recoroded.Results (1) Active phase of the first stage of childbirth analgesia group was significantly shorter than the control group (t =2.182,P ＜ 0.05).The second and third stage of Childbirth and neonatal Apgar score difference between the two groups was not statistically significant.(2)Serum cortisol concentration at T2 analgesia group was significantly lower that of than the control group (P ＜ 0.05).(3) The two groups in maternal blood of CD3+,CD4+,CD4+ / CD8+ were reduced to varying degrees,T3 was reduced significantly (P ＜ 0.05),Analgesia group was significantly lower than that of the control group (all P ＜ 0.05).Conclusion CSEA analgesia in Childbirth can shorten the first stage of Childbirth active period,has no significant effect on the Apgar score,can alleviate the pain and stress reactions such as the suppression of the maternal immune function.

Objective The purpose of this study is to investigate the surgical procedures and curative effect through a small incision on both sides of the scapula for surgical resection the ribs tumor which located un -der ventral surface of the scapula .Methods The group included 11 patients,6 males and 5 females,aged 18 to 49 years.Lesions were bilateral scapula deep square 2~4 single rib bone tumors .Among them there were five ca-ses of fibrous dysplasia ,case of bone cyst ,2 cases of plasma cell tumors and metastatic tumors in 3 cases.Surgery incision through cross-scapular ,to determine which lesions ribs ,cutting the lesions on both sides of the stripping and junction.Results The group obtained a satisfactory excision extension ,one case appeared hemopneumotho-rax postoperatively.Secondly,none of patients occured local recurrence .Thirdly,two patients with metastatic carci-noma died after one year because of multiple metastases .Conclusion Straddling scapular notch is the ideal way to cut off the rib tumor of ventral surface of the scapula .Possessing advantages of a little damage and effect on the function,and rapid recovery .

Objective To establish an easy, rapid and sensitive method for determination of micro 2,4-dinitrotoluene in waste water. Methods Based on the fact that micro 2,4-dinitrotoluene could inhibit the discoloring oxidation reaction of methylene blue by KIO4 in the HC1 solution, micro 2,4-dinitrotoluene was determined using kinetic spectrophotometric method. Results A new kinetic spectrophotometric method for determination of micro 2,4-dinitrotoluene was established. The linear range of the method was 0.20?10~(-5)-1.8?10~(-5) mg/L, the detection limit was 1.7xlO'7 mg/L. When the method was applied to the determination of the 2,4-dinitrotoluene in waste water, its recovery rates in standard addition method were 95.6%-99.1% and the RSDs were 1.5%-2.6%. Conclusion The method was easier to operate and more rapid, which was suitable for the determination of micro 2,4-dinitrtoluene in wastewater.

The specialized teacher troop is the discipline construction,the development key,the teaching leading force and the personnel training quality guarantee. At present stage the quantity and quality of the specialized public health management teacher staff in our school have gradually become the bottleneck for the career development. Only by sharpening teachers' scientific research ability unceasingly, enhances teachers ' individual accomplishment and the teacher troop's overall quality,improving their work quality,can we adapt to the career devel-opment under the new situation.

Objective To establish the quality control standard of Kechuanling Plaster. Methods Semen sinapis in Kechuanling Plaster was identified by TLC. The content of ?-asarone in Kechuanling Plaster was identified by HPLC. Results Semen sinapis in Kechuanling Plaster could be detected by TLC. ?-asarone shows a good linear relationship at range of 0.132～0.308 ?g (r=0.9999). The average recovery was 101.7% and RSD was 2.0%. Conclusion The method was simple, specific and accurate. This study provide a method for the quality control of Kechuanling Plaster.

Objective To investigate the effect of changes in plasma lipid levels on the accumulation of glomerular extracellular matrix in type 2 diabetic rats.Methods Rats were divided into three groups,namely,normal control,diabetes mellitus treated with Fenofibrate,which was gastrically administrated in the dose of 20mg?kg -1 ?d -1 for 22 weeks.A quantitative analysis of the components of glomerular extracellular matrix (ECM) were performed with immunoperoxide (ABC) method and the computer imagine analysis system.Results The result showed that diabetic rats had significantly higher plasma lipid levels and accumulation of ECM including collagen Ⅳ,laminine and fibronectin than the normal control ( P

Objective To identify the influencing factors for pediatric nursese' reporting of adverse events at 3A hospitals in Beijing. Methods Adopting the random sampling of ten 3A hospitals with pediatric wards in Beijing and conducting an questionnaire survey of some nurses in those hospitals. Results The possibility of adverse events reporting increased with the awareness of adverse events which was related with their severity. Except for title, educational background, length of service, position and past experiences were not associated with the barriers. The major perceived barrier was fear of colleague relationship brokenup and some other undesirable consequence. Conclusions Better training of awareness of adverse events and changes of the punitive culture by the roots as well as some regulation or policy were the major solutions to improve incident reporting.
