Objective To explore the effect of Angiotensin Ⅱreceptor inhibitor on proliferation and apoptosis and cell cycle of human en-dometrial cancer cell line induced by estrogen.Methods Human endometrial cancer cells,ishikawa were cultured,and then treated with different concentrations of estrogen or saralasin.Cell proliferation was examined using MTT,and cell cycle and apoptosis were determined us-ing flow cytometry.Results Saralsin inhibited the proliferation of ishikawa cells.After treated with saralasin at 10 min after estrogen induc-tion,cycle was arrested at G1/G0 phase and S phase was reduced in ishikawa cell with significant difference between treatment group and control group.An increase in early apoptosis and late apoptosis occurred at 10min after treatment.Conclusion Saralsin inhibits endometrial cancer cell ishikawa proliferation,induces apoptosis and accumulation in G1/G0 phase in vitro.Therefore,saralsin may be helpful for the treat-ment of endometrial cancer.

Surgical resection is the only potentially curative therapeutic method for patients with gastric cancer. However, con-ventional laparotomy is sometimes associated with considerable complications and mortality rate. This procedure also affects patient quality of life after surgery. Minimally invasive techniques can potentially provide an attractive alternative to current surgical proce-dures in terms of reducing surgical injury and accelerating postoperative recovery. Minimally invasive surgery for gastric cancer has re-cently been reasonably applied to two distinct forms of intervention:endoscopic resection of the tumor and laparoscopic surgery. In the near future, sentinel node navigation and robot surgery will provide more options for treating gastric cancer. Such developments will im-prove the quality of life of patients following surgery for gastric cancer. Various well-designed clinical trials of the minimally invasive techniques are available. Thus, the mode of surgery for gastric carcinoma will be widely accepted and rapidly developed worldwide.

BACKGROUND:The tissue structure of the affected arms of the breast cancer patients is seriously damaged after operation, which often causes the disorder of functional activity and directly affects the lives and work of Breast Cancer patients.OBJECTIVE: To promote the functional recovery of affected-side upperlimb in patients with breast cancer after operation by three-stage functional training and health guidance.DESIGN: Clinical observationSETTING: Department of Nursing, First Affiliated Hospital, China Medical UniversityPARTICIPANTS:Totally 168 patients,to be all female,aged from34 to72 years with the average of 49.65 years, diagnosed breast cancer and received operation in the First Affiliated Hospital of the China Medical University from May 2002 to May 2004, were recruited.METHODS:Self-training was performed on the upper-arm at the affectedtion ( one or two days after operation): Do active and passive exercises of Off-bed stage (3 to 14 days after operation): Do exercises of shoulder joint,hospital( 3 to 6 months), functional exercise and guidance training on the upper arm, 2 to 3 times per day , 15 to 20 minutes per time.

Objective To investigate the effects of different body temperatures on the neuromuscular block induced by different doses of cisatracurium in rabbits. Methods Seventy-two healthy New Zealand white rabbits of both sexes weighing 2.0-2.2 kg were randomly divided into 3 groups (n=24 each): hypothermia group (L), normothermia group (N) and hyperthermia group (H). The rectal temperature was set at 34.5℃, 38.5℃ and 41.8℃ in group L, N and H respectively. Each group was further divided into 4 subgroups (n=6 each) receiving intravenous cisatracurinm 0.33, 0.66, 0.99 and 1.32 mg/kg respectively after rectal temperature was stabilized for 20 min. The animals were anesthetized with iv 20% methane 1 g/kg, tracheostomized and mechanically ventilated (VT 12 ml/kg, RR 60 bpm, I:E = 1:2;FiO2 100% ). TOF was monitored. The onset time, the duration of action (from the end of cisatracurium injection to the recovery of T1 to 5%, 25% and 95% of control height) and recovery index (recovery of T1 from 25% to 75% of control height) were recorded. MAP, HR and rectal temperature were recorded at 5 min before alteration of the body temperature, at 2 min before and 5, 10, 30, 60 and 90 min after administration of cisatracurium. Results (1) With the same dose of cisatracurium the onset time and duration of action were significantly shorter in group H, longer in group L and recovery from N-M block faster in group H, slower in group L as compared with group N. (2) At the same body temperature the onset time was significantly shortened and the duration of action and recovery were significantly prolonged as the dose of cisatracurium increased. (3) There was significant difference in the effect of interaction between different doses of cisatracurium and different temperatures on the onset time. (4) With the same dose of cisatracurium MAP was significantly decreased in group H, increased in group L, while HR was significantly increased in group H, decreased in group L. Conclusion The neuromuscular blocking effect of cisatracurium is decreased when the body temperature is increased and vice versa. The neuromuscular blocking effect of cisatracurium (0.33-1.32 mg/kg) is dose-dependent at the same body temperature. There is interaction between the two factors.

Connection between the superior colliculus(SC)and the dorsal and ventral lateral geniculate nuclei (LGd and LGv) were studied in adult golden hamsters using anterograde and retrograde pathway tracing methods 1. In four hamsters, the cytoarchitecture of the SC, LGd and LGv was examined in brain sections stained with Nissl's or Loyez's method. 2. A single injection of a mixture of ~3H-leucine and ~3H-proline was made into various regions of the SC in each of 4 animals (1 day survival) for studying the pattern of terminal distribution of the projections from the SC to the ipsilateral LGd and LGv. In animals where the injection site was located in the superficial gray layers of the lateral portion of the SC, labelled terminals were found in the caudal lateral part of the LGd and LGv. In the case where the injection was restricted in more medial part of the SC, the terminal labelling was observed in the rostral lateral portion of the lateral geniculate nuclei. 3. One day after an injection of horseradish peroxidase (HRP) into the LGd (4 animals), LGv(2 animals), or LP(2 animals) labelled neurons were observed in the superficial gray layers of the ipsilateral superior colliculus. No HRP-labelled neuron was detected in deeper laminae in the colliculus. These results indicate that neurons in the superficial gray layers of the SC project to the ipsilateral LGd and LGv, and the projections are organized topogra- phically according to the retinotopic or visual field map

This paper reports the observation on the distribution of succinic dehydrogenase of the cochlea in normal guinea pig. The method we adopted is as follows: The temporal bone was rapidly removed and the apical portion of the cochlea and the round window were perforated after decapitation under the temperature at 0? to 4℃. Incubation solution was infused into the apical portion of the cochlea and flowed out through the round window. The above procedure was carried out within 3 min. Then the specimen was put into incubation solution for 30 min at 37 C. The same infusion pathway from apical hole to round window was adopted, to introduce a cold, buffered formol sucrose solution for fixation. After first fixation by infusing, the cochlea in the fixative was subjected to a vacuum system for 20～30 min, and finally put into refrigerator to complete fixation. The specimen was then decalcified in 10 per cent EDTA, and immersed in 10 and 20 per cent gelation successively for embedding. The frozen sections was cut into 15? thick midmodiolar sections in a cryostat. This observation reveals that the inner and outer cell, the cell of spiral ganglion and the stria vascularis showed a very strong enzyme activity, while the tectorial membrane, the basilar membrane and other cells showed no activity. The results obtained and the methods are discussed.
