Colorectal cancer is a common malignant tumor of digestive tract, and the risk of inflammatory bowel disease developing into colorectal cancer is significantly increased. Immune signaling pathways NF-κB, IL-6/STAT3, COX-2/PGE2, IL-23/Th17 and TLRs have been confirmed to promote the transformation from colitis to colorectal cancer. NOD2 and intestinal microbes also participate in the regulation of inflammation mediated carcinogenesis. Chronic inflammation is a potential risk for colorectal cancer, and anti-inflammatory drugs may play a chemical preventive role. In this review, we summarize the signaling pathways involved in inflammation-associated colon carcinogenesis and evaluate the chemoprophylaxis of colon cancer.

BACKGROUND: Yishen jiangu granule is one of sheer traditional Chinese drugs, which has good effect of tonifying kidney, strengthening bone, reinforcing the spleen, nourishing qi and improving the body condition, mainly used to prevent the lassitude, rickets, osteomalacia and calcium-deficiency induced by kidney-deficiency.OBJECTIVE: To observe the preventive effect of yishen jiangu granule on the reproductive organs, physical strength as well as the ability of stress, and compare with the effect of longmu zhuanggu preparation which was characterized by invigorating spleen and replenishing qi, and tonifying kidney and replenishing essence.DESIGN: Completely randomized controlled design.SETTING: Institute of Traditional Chinese Medicine, Chengde Medical CollegeMATERIALS: A total of 180 Kunming mice, weighing 25-30 g, of half gender, of clean grade, were selected in this study. Longmu zhuanggu granule, which was composed of root of tangshen, tuckahoe, rhizome of lagehead atractylodes, huai yam, astragalus root, schisandra fruit, keel,oyster shell, tortoise plastron, dwarf lilyturf, Chinese date, licorice root,vitamin D, etc., was provided by Wuhan Jianmin Pharmaceutical Factory (batch number: 960618). Yishen jiangu granule, which was composed of 6 kinds of traditional Chinese medicine such as dark plum, Chinese wolfberry, oyster shell, etc., was manufactured by Institute of Traditional Chinese Medicine of Chengde Medical College (batch number: 950510).Hydrocortisone injection was produced by Bohai Pharmaceutical Factory of Tangshan city (batch number: 940303).METHODS: The experiment was completed in Institute of Traditional Chinese Medicine, Chengde Medical College from January to October 1997. ① A total of 180 mice were randomly divided into 6 groups with 30 in each group: normal group (5.0 mL/kg saline, muscle injection); model group (25 mg/kg hydrocortisone for the mice model with kidney-yang deficiency, muscle injection); longmu zhuanggu granule group (5.0 g/kg longmu zhuanggu granule, and 25 mg/kg hydrocortisone); three groups of yishen jiangu granule at different dosages (perfused respectively with yishenjiangu granule at the dosages of 1.25 g/kg, 2.5 g/kg and 5.0 g/kg;meanwhile, 25 mg/kg hydrocortisone, muscle injection). The mice were administered successively for 14 days. ② In 12 hours after giving the last medicine, each group was divided into 3 parts to go on with the following 3 sub-experiments: Firstly, the spermary and uterus of mice were taken out to determine their weight, then calculate the indexes (mass of uterus/body mass of mice); secondly, the mice were put into the water [water depth:30 cm, water temperature: (20±0.5) ℃], burden of tail of mice was weighed 10% of the body mass, then timed immediately, when the mice could not immerge from the water after their heads sank into the water for 10 seconds.It showed that they were exhausted (the time was regarded as the swimming time of mice); thirdly, 10 g sodalime was added into each bottle with wide neck whose volume was 150 mL, then one mouse was put into each of them,covered them and timed immediately. The breath of the mice was observed until they stopped breathing, then timing was over. This was the bearing time of mice on anoxia under normal pressure. ③ Difference of statistical significance between groups was determined by t-test.MAIN OUTCOME MEASURES: The mass indexes of reproductive organs, swimming time and the bearing time on anoxia under normal pressure of the mice in all groups.RESULTS: A total of 180 mice were all involved in result analysis. ① The mass indexes of spermary in mice in normal group, longmu zhuanggu granule group and yishen jiangu groups at high and middle dosages were significantly higher than those in model group (P ＜ 0.05-0.01); the mass indexes of uterus in mice in normal group, longmu zhuanggu granule group and yishenjiangu groups at high dosage were significantly higher than those in model group (P ＜ 0.01). ② The swimming time of the mice in model group was significantly shorter than that in the other 5 groups (P ＜ 0.01). ③The bearing time on anoxia under normal pressure of the mice in model group were significantly shorter than that in the other 5 groups (P ＜ 0.01).CONCLUSION: Yishen jiangu granule has the remarkable effect on kidney-tonifying. It can remarkably relieve the reproductive organ atrophy of the mice with kidney-yang deficiency, has remarkable effect on antifatigue, and also can increase the ability of stress.

Objective To evaluate the feasibility of an intelligent three-dimensional ultrasound technique (Smart mid-sagittal planes,Smart MSP) in automatically detecting the fetal cranial mid-sagittal view.Methods Two hundred and forty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using the Smart MSP by six doctors divided into three groups according the different experiences.Another two doctors were then invited to score the images acquired and to compare the successful rates of 6 doctors for acquiring fetal cranial mild-sagittal view according to the doctors' experience.Results The overall successful rate of acquiring the mid-sagittal view was 97.08％ (233/240) with the bipartial diameter plane (BPD plane) as the starting plane and 98.33(237/240) with the trans-cerebellum plane as the starting plane by using Smart MSP program.The successful rates in three groups were similar but the consumed times were different(P ＜0.05).The experienced doctors consumed less time than non-experienced doctors.The scores were also different in three groups.The scores of experienced doctors (group B and C) were significantly higher than that of non-experienced doctors (Group A) (P ＜0.05).There was no significant difference in the scores between experienced doctors (group B and C) (P＞0.05).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial mid-sagittal plane,which may become an effective tool to screen the fetal midline anomalies in future.

OBJECTIVE: To observe the preventive effect of total flavones from stem and leaf of scutellaria baicalensis on experimental hyperlipidemia in rats. DESIGN: Randomized controlled trial. SETTING: Institute of Traditional Chinese Medicine, Chengde Medical College MATERIALS: The experiment was conducted in the Institute of Traditional Chinese Medicine, Chengde Medical College from March 1999 to January 2000. Totally 60 male Wistar rats with beginning body mass(200±10)g were provided by Experimental Animal Research Institute, Chinese Academy of Medical Science (Qualification No.01-3008). INTERVENTIONS: Sixty rats were randomly divided into 6 groups:normal control group, high-lipid model group, the groups of 12.5, 25 and 50 mg/kg of total flavonoids (TF group) and clofibrate group (25 mg/kg),with 10 rats in each group. The rats in the normal control group were fed with basic feed. The rats in the high-lipid model group were fed with highlipid feed.Rats in the TF group and clofibrate group were fed synchronously with high-lipid feed and total flavonoids or clofibrate for consecutive 30 days. The change of blood lipid was observed. MAIN OUTCOME MEASURES: The levels of total cholesterol (TC),triglyceride (TG), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) in the serum of all the rats were measured with CL-7200 type automatic biochemistry analytical instrument at the end of the experiment, and the atherosclerosis indexes (AI) were calculated (AI=TC-HDL-C/HDL-C).RESULTS: Totally 60 rats entered the result analysis. ① Level of TC in the serum of rats: The level in the high-lipid model group was significantly higher than that in the normal control group[(5.01 ±1.05,2.33±0.35)mmol/L, (P ＜ 0.01 )]; The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (4.15±1.12, 3.03±0.31,2.98±0.56)mmol/L, there was no significant difference between group of 12.5 mg/kg of TF and model group (t=1.74, P ＞ 0.05), but there was significant difference between groups of 25 mg/kg and 50 mg/kg of TF and model group (t=5.66-5.23, P ＜ 0.01). ②Level of TG in the serum of rats: The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (1.22±0.56)mmol/L,(1.56±0.41)mmol/L,(1.24 ±0.45)mmol/L respectively, compared with model group(2.14±0.74) mmol/L, there was significant difference (t =2.19-3.45, P ＜ 0.05-0.01). ③ LDL-C level of the serum in the rats: The level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (2.67 ±0.45) mmol/L, (1.41 ±0.23)mmol/L, (1.29±0.23) mmol/Lrespcrtively,compared with model group[(3.94±0.42)mmol/L, there was significant difference (t=5.77-12.71, P ＜ 0.05-0.01). ④ HDL-C level of the serum in the rats: the level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was (0.72±0.23)mmol/L,( 0.91±0.32)mmoL/L,(1.05±0.23)mmoL/L respectively, there was no significant difference between group of 12.5 mg/kg of TF and model group[(0.56±0.21)mmol/L, but there was significant difference between groups of 25 mg/kg and 50 mg/kg of TF and model group (t=2.92-4.38,0.05 ,P ＜ 0.05-0.01).⑤AI: the level in the groups of 12.5 mg/kg, 25 mg/kg and 50 mg/kg of TF was(2.96 ±1.35), (2.10±0.97), (1.55±0.41)respectively, compared with model group (4.23±0.65) , there was significant difference (t =3.54-9.49 ,P ＜ 0.01). CONCLUSION: TF has significantly inhibitory effect on the increase of TC, TG and LDL-C in the serum of the rats induced by high-lipid feed; it can also increase the level of HDL-C, indicating TF has obviously preventive effect on experimental hyperlipidemia in rats.

OBJECTIVE: Through the use of the categories of auditory performance (CAP-II), the speech, spatial and qualities of hearing scale-parents' version (SSQ-P), children using hearing implants quality of life (CuHI-QoL) in patients with prelingual hearing impairment to compare the rehabilitation effect between preoperative and postoperative auditory performance, speech behavior and quality of life and at the same time to figure out dose rehabilitation effect connected to age. METHOD: Mainly used classification method to compare the audotory performance, speech behavior and quality of life of 50 patients before and after 2.5 years after the implantation. At the same time these 50 patients are divided on the basis of the age received the surgery, A group received the surgery before 6(1.0-5.9) years old and group B received the therapy after this age (6.0-10.9). Their auditory performance, speech behavior and quality of life were all evaluated. RESULT: There were statistical difference between two kinds of classification method of CAP-II. In the study of SSQ-P and CuHI-QoL, there was no statistical difference in well-being and happiness before and 3 years after the implant, also there was no statistical difference in parental stress between two age groups. In addition to the above two, the rest all have statistical significance. CONCLUSION After the implant, postoperative auditory performance, speech behavior and quality of life all had improved and the smaller the age, the better the performance.

OBJECTIVE: To explore the methods of the larygeal recurrent nerve dissection in different and difficult thyroid surgery, so as to minimize damage and improve the safety of the operation. METHOD: The process and methods in different laryngeal recurrent nerve dissection about 52 hospitalized patients from 2010 to 2012 were retrospectively analyzed. These cases include large nodular goiter, nodular goiter behind the sternum or located in the lower pole of the thyroid gland, thyroid cancer, tumors of parathyroid gland, etc. We studied the conditions of lesions involving the laryngeal recurrent nerve and the defensive measures to protect the nerve. RESULT: The laryngeal recurrent nerve was dissected successfully in 50 cases, except 2 cases whose laryngeal recurrent nerve were violated by thyroid cancer. CONCLUSION When we dissect the laryngeal recurrent nerves in different and difficult thyroid, the glands and tumors were mostly needed to be freed and turned inward and forward. After that, the laryngeal recurrent nerves can be dissected successfully with the markers of tracheoesophageal groove, inferior thyroid artery and/or angle under the thyroid cartilage.
