Objective To investigate the role of T cell factor-4 (TCF-4) in the carcinogenesis of colorectal cancer. Methods Relevant references about TCF-4 and the carcinogenesis of colorectal cancer, which were published recently domestic and abroad, were collected and reviewed. Results For TCF-4 gene, multiple isoforms are generated by way of alternative splicing, which encode different proteins. TCF-4 protein is sequence-specific DNA binding protein and is incapable of activating or repressing transcription independently, but it can interact with distinct partners to lead to different effects through multiple domains. Conclusion TCF-4 might be viewed as nuclear vehicles targeting other auxiliary proteins to a specific set of promoters and functions as molecular switch during the carcinogenesis of colorectal cancer.

Objective:To analyze the clinical characteristics of infantile laryngopharyngeal reflux diseases(LPRD) with cyanosis as the main manifestation, improve diagnosis of the disease and avoid missed diagnosis.Methods:Clinical data of children diagnosed with LPRD at Shenzhen Children′s Hospital from September 2015 to October 2018 were retrospectively analyzed.Results:Cyanosis was the predominant symptom in all 5 cases.The course ranged from 3 days to 4 months.Laryngomalacia was observed in 4 cases.Two patients were treated with esophageal atresia, 1 with esophageal stenosis and 1 with severe tracheomalacia.All 5 cases had vocal cord and arytenoid mucosa edema.The Ryan index was 65.92-1 444.5 in the upright position and 3.73-431.44 in the supine position.Three cases were treated with erythromycin and ceftriaxone according to the etiology.Two cases were treated with motilium at the same time, and 3 cases were with omeprazole oral.One case was recovered after 8 weeks and the Ryan index became normal.Symptoms were alleviated in 3 patients after 4 weeks, drugs were stopped by parents.One case still had cyanosis during medication, the symptoms were significantly relieved after tracheal stent implantation.Conclusion:LPRD is closely related to children′s respiratory and digestive system diseases.LPRD should be taken into account when children show unexplained clinical symptoms of respiratory and digestive system, and laryngoscopy and DX-pH detection should be performed as soon as possible to avoid missed diagnosis.

Objective To study the effects of Ginkgo biloba extract (GBE) on free radical metabolism of different fiber types of quadriceps in exercised rats and its mechanism. Method Increasing load exercised rat model was selected. The test rats were orally given GBE aqueous suspension (100 mg/ kg?d), and the controls with water. The levels of malondialdehyde (MDA) and the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px) of red muscle, white muscle and whole quadriceps of exercised rats were examined before exhaustive exercise, at instant,24h and 48h after strenuous exhaustive exercise. Results Compared with the controls,MDA contents were 49.69% higher in white muscle (P

Seven crystalline compounds have been isolated from the soft coral Nephthea Bayer collected from the South China Sea, four of them have been identified to be 24-methyl-cholesta-5,24 (28 )-diene-3B, 7B,19-triol (1) , 24-methylcholesta-5, 24 (28)-diene-3B,19-diol (2), 24-methylcholesta-5,24(28)-diol-3B-ol (3) and l-octadecyl-2,3-dihydroxypropyl ether (4), respectively based on their data of IR, MS, 1HNMR and 13CNMR.

Objective To observe the therapeutic effect of suspending-needle therapy combined with modified Zhengan Xifeng Decoction for the treatment of primary facial spasm,and to explore an effective traditional Chinese medicine therapy for primary facial spasm.Methods A total of 65 qualified patients were randomly divided into trial group (33 cases) and control group(32 cases),which was treated with suspending-needle therapy combined with modified Zhengan Xifeng Decoction,Carbamazepine tablets respectively.Twenty-eight days constituted one course of treatment.After treatment for one course,therapeutic efficacy of the two groups was evaluated,and the degree of facial spasm was assessed.Results (1) After one course of treatment,the markedly-effective rate of the trial group was 84.8％,and that of the control group was 62.5％,the difference being significant(P ＜ 0.05).(2) After treatment,the degree of facial spasm in the two groups was much improved as compared with that of the control group (P ＜ 0.05 or P ＜ 0.01),and the improvement in the trial group was superior to that in the control group (P ＜ 0.01).Conclusion Suspending-needle therapy combined with modified Zhengan Xifeng Decoction has better effect on relieving facial spasm of the primary facial spasm patients than Carbamazepine tablets.

Objective To study the effect of point electric stimulation for urinary incontinence after postoperative cerebral hemorrhage.Methods Eighty patients with urinary incontinence after postoperative cerebral hemorrhage were randomly divided into treatment group and control group(n=40 case). Point electric stimulation was given to the treatment group, and Oxybutynin hydrochloride sustained release tablets was given orally to the control group. Index of urinary diary and bladder capacity in both groups before treatment and after 3 weeks of treatment were observed.Results After 3 weeks of treatment,the total effective rate(87.2%vs. 65.8%,χ2=4.916) in the treatment group were better than the control group (P<0.05). The times of voided (10.15 ± 2.21 times/24 hvs. 18.63 ± 3.42 times/24 h,t=12.956), the times of urinary incontinence (2.18 ± 1.04 times/24 h vs. 6.19 ± 2.16 times/24 h,t=10.421), the average voided volume (293.38 ± 16.32 mlvs. 180.82 ± 15.43 ml, t=31.083), the initial sensory capacity of bladder (276.73 ± 20.95 mlvs. 186.43 ± 21.14 ml,t=18.825), the maximum capacity of bladder (492.81 ± 23.72 mlvs. 293.81 ± 24.46 ml,t=36.244), the residual urine volume(13.25 ± 5.83 mlvs. 34.63 ± 6.25 ml,t=15.527) in the treatment group were significantly better than those in the control group (P<0.01).Conclusions The treatment of point electric stimulation can reduce the symptoms of urinary incontinence.

Objective: To observe the clinical efficacy of combined needle-embedding and SSRIs for depressive sleep disorder. Method: Upon admission, 71 depression cases were randomized into needle-embedding group of 24 cases, using combined needle-embedding and SSRIs, acupuncture group of 21 cases, using combined acupuncture and SSRIs, and medication group of 26 cases, using SSRIs alone. After 1, 2, 4 and 6 weeks of treatment, the HAMD sleep scores were compared. Result: The HAMD sleep scores in the needle-embedding and acupuncture group were remarkably superior to the medication group and there was significant statistical difference after 1, 2 and 4 weeks of treatment (P<0.01). However, there was no statistical difference after 6 weeks of treatment. Conclusion: SSRIs can improve HAMD sleep scores. The combined needle-embedding or acupuncture with SSRIs can work faster and better than medication alone. There was no statistical difference between needle-embedding and acupuncture group, however, needle-embedding can reduce the treatment frequencies and therefore has more active clinical meaning.

Objective To explore the morbidity and risk factors of postoperative delirium in the patients undergoing coronary artery bypass grafting (CABG).Methods A total of 286 patients were continuously enrolled for CABG surgery from January to December 2013 in cardiac surgery ward in Beijing Anzhen Hospital.Delirium Rating Scale-Revised-98 was used as the diagnostic tool for the analysis of the morbidity and risk factors of postoperative delirium.Results (1) Delirium occurred in 24 patients of 286 patients and morbidity of postoperative delirium was 8.4％.Sixteen of 24 patients (66.7％) suffered from transient delirium (＜24 h).Eight of 24 patients (33.3％) suffered from continuous delirium (≥48 h).(2) The common clinical presentation of postoperative delirium included increased psychomotor activity, a disordered sleep-wake cycle and a reduced level of consciousness.(3) Univariate Logistic regression analysis results showed that delirium was associated with advanced age over 70 years old (OR =3.05, 95％ CI 2.55-72.94, P =0.023), previous cerebral infarction(OR =1.78, 95％ CI 1.07-2.96, P =0.026), previous brain heamorrhage (OR =1.99, 95 ％ CI 1.20-3.31, P =0.003), surgery time (OR =1.05, 95％ CI0.05-2.04, P =0.047), intensive care unit (ICU) staying time (OR =2.87, 95％ CI 1.43-5.72, P=0.003), use offentanyl (OR=2.78, 95％ CI 1.02-7.57, P=0.045).(4) The multiple Logistic stepwise regression analysis indicated that the perioperative risk factors of delirium included advanced age over 70 years old (OR =3.196, 95％ CI 1.574-6.488, P =0.001), cerebrovascular accident history(OR =2.610, 95％ CI 1.538-4.431, P =0.000) and ICU duration time(OR =1.480, 95 ％ CI 1.070-2.046, P =0.018).Conclusions The morbidity of postoperative delirium after CABG is 8.4％.Many predisposing and precipitating factors contribute to postoperative delirium.These factors include age ＞ 70 years, cerebral infarction and ICU staying time.Assessment and preventive strategies should be considered to reduce the incidence of delirium, particularly among those patients with high risks.

Objective To compare iso-osmolar iodixanol and low-osmolar iohexol for the incidence of contrast- induced nephropathy(CIN) in patients with chronic congestive heart failure undergoing coronary interventional therapy. Methods The study included 220 consecutive patients with chronic congestive heart failure and undergoing coronary angiography (CAG) with or without percutaneous coronary intervention (PCI) bewteen Janurary 2015 and May 2016. Study participants were divided into two groups by random digits table:iso-osmolar group (110 patients) and low-osmolar group (110 patients). The patients in iso-osmolar group were given iodixanol, and the patients in low-osmolar group were given iohexol. Serum creatinine (SCr), glomerular filtration rate (GFR) and cystatin C (CysC) were detected before the procedure and on the first, third day after the procedure. Then, the incidence of contrast-induced nephropathy (CIN) in two groups within 72 h of the procedure were observed and compared. Results The levels of SCr, GFR, CysC before operation had no significant differences (P>0.05). The levels of SCr in two groups on the first day after operation were increased, but there was no significant difference between two groups (P>0.05). On the first day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.05). On the third day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.01). The overall incidence of CIN was 20.9%(46/220). The incidence of CIN in low-osmolar group was 29.1%(32/110), in iso-osmolar group was 12.7%(14/110), and there was significant difference (P<0.05). Conclusions In chronic congestive heart failure patients undergoing coronary interventional therapy, the iso-osmolar contrast iodixanol is associated with a lower incidence of CIN compared with low-osmolar iohexol.

Objective To explore the imaging features of bone marrow edema(BME)and soft tissue edema(STE)caused by bone tumors and tumor-like lesions.Methods Ninety nine patients with bone tumors and tumor-like lesions which were proved by surgical pathology were reviewed.The patients were divided into benign and malignant groups.Evaluation parameters included the size and signal intensity of BME and STE,the features of enhancement,the bone sclerosis and its relation with BME,and joint effusion,et al.The data of two groups were analyzed by X2 test.Results There were 40 patients in benign group and 59 patients belonged to malignant group.BME and STE demonstrated low signal on T1-weighted images and high signal on fat-suppressed T2-weighted images.Some BMEs demonstrated low signal on T2weighted images,which corresponded to sclerosis on X-ray film and(or)CT.Both BME and STE demonstrated uniform enhancement.There were statistically significant differences between benign and malignant groups including the frequency of BME.sclerosis.the median of the size of the BME and STE (P<0.05),which were 57.5%(23/40),25.0%(10/40),2.7 cm,1.3 cm,and 32.2%(19/59).3.4%(2/59),1.6 cm,1.7 cm respectively.No significant differences between the frequency of STE,joint effusion in 2 groups(P>0.05).Conclusions Both benign bone tumors and tumor-like lesions and malignant bone tumors can be accompanied by BME and STE.The size of BME in the benign bone tumors and tumor-like lesions is bigger than those in malignant ones,and the size of STE in malignant bone tumors is bigger than benign ones.
