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.

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.

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.

Objective To discuss the metabolic characteristics and significance of peripheral blood cell and T lymphocyte subgroup in patients with air condition disease.Methods Thirty-six patients diagnosed as air condition diseases with fever and 30 patients diagnosed as non-fever patients enrolled this study as observation group(fever group and non-fever group respectively),and 30 health population were used as control.The changes of peripheral blood cell and T lymphocyte was measured using regular blood examination and flow cytometry.Results(1)No significant diffence on white blood cell was found between the three groups(F =1.89,P =0.134);(2)The percentage of neutrophils was(68.13 ±5.67)％,(53.24 ±8.36)％ and(61.25 ±6.31)％ respectively in the fever,non-fever and control group,respectively.Compared to the non-fever and control group,the percentage of neutrophils were significantly higher(t =6.64,9.13; P =0.018,0.027 respectively).No signiciant difference in the percentage of neutrophils was found between the non-fever group and control group(P =0.356,0.125).The percentage of lymphocyte percentage was(31.66 ±7.11)％,in the fever group,which was significantly higher than those of(43.67 ±8.17)％ and(30.98 ± 8.76)％ in the nonfever and control group(t =5.59,4.98 ; P =0.022,0.021 respectively).(3)The percentage of CD4 + was (36.351 ± 6.531)％,(42.676 ± 5.169)％ and(39.253 ± 5.461)％ in the fever,non-fever and control group,respectively.The percentage of CD4 + in the fever group was significantly lower than that in the non-fever group(t =1.28,P =0.039),whereas the percentage of CD4 + in the non-fever group was significantly higher than that in the control group(t =3.80,P =0.048).The percentage of CD8 + was(28.084 ± 7.344)％,(21.186 ± 6.331)％ and(24.607 ± 7.108)％,respectively.Compared to nonfever group,the percentage of CD8+ was significantly higher(t =3.17,P =0.016).(4)The ratio of CD4 +/CD8 + was(1.629 ±0.554)％、(2.380 ± 0.391)％,and(2.079 ± 0.659)％.Compared to the non-fever and control group,the ration in the fever group was siginificantly lower(t =19.21,P ＜ 0.001 ; t =6.98 ; P =0.006),whereas compared to the control group,the ratio in the non-fever group was significantly higher(t =8.68,P =0.031).Conclusion The changes of T subgroup show the unbalance immunity function network in patients with air condition disease.

On the basis of outpatients' medical records concerning primary liver cancer (PLC), data of 552 patients (with 2020 effective prescriptions) from the Outpatient Department of Changhai Hospital treated by Professor Ling Changquan were collected. The nature, flavor and meridian distribution of the herbs used in the prescriptions were summarized by frequency method, and the features of the herbs used according to syndrome differentiation were analyzed by logistic regression. The couple herbs used were analyzed by cluster analysis. All the data were analyzed in combination with the experience of the specialist. It showed that most of the frequently used herbs were herbs for invigorating the spleen to promote appetite, removing toxic materials to inhibit tumor growth, and activating blood circulation to dissipate blood stasis. These herbs are mostly of plain or cool nature, and mainly of sweet, bitter, or acrid taste. It also showed that the most frequently used herbs for qi deficiency were Astragalus membranaceus, Atractylodes macrocephala, and Pseudostellariae; Caulis Spatholobi and Chinese jujube for blood asthenia; Fructus Corni and Ophiopogon japonicus for yin deficiency; Agastache rugosa, Semen Plantaginis and Poria for water-dampness; cape jasmine fruit and baikal skullcap root for heat excess; peach seed and Radix Paeoniae Rubra for blood stasis; Curcuma wenyujin, Akebia trifoliata and Bupleurum chinese for qi stagnation. A total of 19 pairs of couple herbs were summarized by the cluster analysis.

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.

Background and purpose:Resistance to antitumor agents is a major cause of treatment failure in patients with breast cancer. Research has shown that, tumor stem cell marker aldehyde dehydrogenase 1 (ALDH1) is related with some anticancer drugs (such as cyclophosphamide, cisplatin) resistance, and the content of ALDH1 in tumor cells after treatment is higher than that before treatment. Breast cancer resistance protein (BCRP) is not expressed in normal tissues, but high expressed in breast cancer of after treatment, it may be associated with the mechanism of tumor drug resistance. This study was to investigate the correlation between expression and the relationship between these two kinds of protein ALDH1, BCRP and clinical pathological characteristics. Methods:Immunohistochemistry was performed to detect the expression of ALDH1 and BCRP in breast inifltrating ductal carcinoma tissues, and whether there is a correlation between and explore their relationship with clinical pathological features and their expression. Results:The expression of ALDH1 protein and BCRP protein in breast cancer and paracarcinoma breast tissues has signiifcant difference(χ2=14.685, P=0.000;χ2=12.243, P=0.000).The expression of ALDH1 with patients age, pathologic stage, axillary lymph node metastasis, histological grading, ER, PR, and HER-2 state were not relevant(P>0.05). HER-2, BCRP protein, expression was higher in cancer tissue (χ2=5.289, P=0.021). There were no relevant with the expression of BCRP with patients age, pathologic stage, axillary lymph node metastasis and histological grading, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor (HER-2) (P>0.05). Conclusion:ALDH1 proteins may be an independent factor compared with occur drug resistant protein, and participate breast cancer drug resistance in the chemotherapy and tumor invasion and metastasis of malignant biological behavior.
