Caveolin-1 is an important surface structural marker of Caveolae. It is closely involved in the proliferation, apoptosis, invasion, metastasis, angiogenesis, signal transduction and multi-drug resistance of various tumor cells. Recent studies have found that altered Caveolin-1 expression has dual roles, as a tumor suppressor and promoter, in different stages of gastrointestinal cancer development and progression. The exact mechanisms of Caveolin-1s' involvement in the development of gastrointestinal cancer remain to be clarified and have attracted the attention of a lot of researchers.

Colorectal cancer is one of the most common malignant tumors. Though the development of multidisciplinary therapy has largely improved the therapy effects, many patients still died of local recurrence and metastases after surgery. Circulating tumor cell (CTC) originates from primary tumor tissues and has a close relationship with cancer metastases and prognosis. This review summarizes the CTC detection methods and relevant clinical research on CTC in recent years.

AIM: To observe the efficacy of Medpor porous polyethylene implants in treatment of enophthalmos combined with orbital fracture.
METHODS: Seventeen cases ( 17 eyes ) with enophthalmos caused by orbital fracture underwent surgical treatment with Medpor porous polyethylene implants. All accepted a 6-mo follow-up and the data of enophthalmos, eyeball movement and diplopia were collected.
RESULTS: The average difference of exophthalmos between damaged eyes and undamaged eyes was (3. 4±1. 5 ) mm preoperatively, two cases had residual 1mm enophthalmos 6mo after surgery, while other 15 cases were completely corrected. Seventeen cases suffered from eyeball movement restriction and diplopia preoperatively, 16 cases had normal eyeball movement without diplopia 6mo after surgery, 1 case with limitation of abduction and horizontal diplopia. There was no extrusion, rejection, infection or other complications occurred during follow-up.
CONCLUSION: Medpor porous polyethylene implants can effectively improve the orbit volume to repair enophthalmos caused by orbital fracture.

Objective To investigate the accuracy of end-tidal carbon dioxide (PETCO2) in reflecting arterial carbon dioxide (PaCO2) during mechanical ventilation via laryngeal mask airway (LMA) in children. Methods Fifty-two ASA Ⅰ patients, aged 2-9 yr, weighing 10-30 kg, undergoing orthopaedic surgery under general anesthesia, were randomized into 2 groups (n = 26 each) : LMA group and endotracheal tube (ETT) group. After anesthesia was induced with fentanyl, propofol and succinycholine, LMA or ETT was inserted and the children were mechanically ventilated. After the hemodynamics was stable, arterial blood samples were obtained to detect PaCO2, and PETCO2 was recorded simultaneously. Results There was no significant difference in PaCO2 and PCT CO, between groups LMA and ETT ( P ＞ 0.05) . There was no significant difference between PaCO2 and PETCO2 in LMA group (P ＞ 0.05). Conclusion When mechanical ventilation is performed via LMA in children, PETCO2 can reliably reflect PaCO2 and guide the regulation of ventilatory parameters.

Objective To investigate the expression of Skp2 and Cx43 in cervical carcinoma and to study their relationships and clinical significance. Methods The expression of Skp2 and Cx43 was examined by immunohistochemical method in 48 cases of cervical carcinoma tissue, 84 cases of cervical intraepithelial neoplasia (CINⅠ - Ⅱ 45 cases, CINⅢ 39 cases), 28 cases of chronic cervicitis. Results Skp2 expression in cervical carcinoma was higher than that in the CINⅠ - Ⅱ and chronic cervicitis (P <0.05), Cx43 expression was lower in cervical carcinoma than that in the CINⅢ, CINⅠ - Ⅱ and chronic cervicitis (P <0.05). The expression of Skp2 was correlated with histological differentiation and lymph node metastasis (P <0.05). The expression of Cx43 was correlated with the lymph node metastasis (P <0.05). Besides, the expression of Skp2had a negative correlation with that of Cx43. Conclusion Skp2 and Cx43 may play an important role in the genesis and development of cervical carcinoma.

BACKGROUND: Cardiac function of patients with hypertension is impaired to various extents. How does the impairment level of cardiac function of patients with hypertension differ at various stages?OBJECTIVE: To observe cardiac function of patients with hypertension at various stages and compare the indexes with those of healthy people.DESIGN: Case-control and comparative observation.SETTING: Department of Special Treatment, General Hospital of Shenyang Military Area Command of the Chinese PLA.PARTICIPANTS: Totally 100 patients with hypertension were selected from the Internal Medicine Department of General Hospital of Shenyang Military Area Command of the Chinese PLA between October 2002 and May 2003. Among them, 30 cases of hypertension were at stage Ⅰ , 40 at stage Ⅱ and 30 at stage Ⅲ. At the same time period another 30 healthy people were selected as the control group. All the subjects signed the informed consent.METHODS: Cardiac function of the included subjects were detected with XJS-Ⅰ cardiac function testing equipment. Patients were tested at supine position and electrode was put on the basis of four-probe method.Breath was held at the end of expiration; meanwhile, lead electrocardiograph Ⅰ, cardiophonogram, cardiac admittance differential coefficient method and beating of carotid artery were recorded. Various indexes were processed with the computer. Detected indexes were heart rate, ejection prophase, ejection time of left ventricle, ejection prophase/ejection time of left ventricle, delay time of electro-machine, isovolumetric contraction time, isovolumetric contraction time/ejection time of left ventricle, time of pulse wave transmission, stroke volume, cardiac output, cardiac index,stress index of myocardial contraction, total peripheral resistance, and vascular compliance.MAIN OUTCOME MEASURES: Comparison of cardiac function between hypertensive patients at various stages and healthy people.RESULTS: All the 100 patients with primary hypertension and 30healthy people entered the final analysis. [1] Ejection prophase, isovolumetric contraction time, peripheral resistance, ejection prophase/ejection time of left ventricle and isovolumetric contraction time/ejection time of left ventricle: Those of hypertensive patients were obviously longer or stronger than those of the healthy subjects (P ＜ 0.01); those of patients with hypertension at stages Ⅱ and Ⅲ were obviously longer or stronger than those of patients with hypertension at stage Ⅰ (P ＜ 0.01). [2] Stroke volume, cardiac output, stress index of myocardial contraction, vascular compliance, time of pulse wave transmission and cardiac index: Those of hypertensive patients were obviously shorter or weaker than those of the healthy subjects (P ＜ 0.01); those of patients with hypertension at stages Ⅱ and Ⅲ were obviously shorter or weaker than those of patients with hypertension at stage Ⅰ (P ＜ 0.01). Among the indexes mentioned above, vascular total peripheral resistance of hypertensive patients at stage Ⅲ was obviously stronger than that of hypertensive patients at stage Ⅱ (P ＜ 0.05),but vascular compliance of the latter ones was obviously than that of the former ones (P ＜ 0.05).CONCLUSION: Cardiac function of patients with hypertension is decreased as compared with that of healthy people, and tends to further decrease with the development of hypertensive condition.
