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.

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 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

OBJECTIVE: To investigate the clinical efficacy of self-made 32P applicator for treating different kinds of keloid. others were treated with surgical excision combined with self-made 32P applicator. The 32P applicator was shaped according to the size and shape of the diseased region and the application time was calculated according to the dose rate and the decay correction. 4.0-5.0 Gy was applied in every diseased region in each of the four days (one course), and 4-6 courses in total was required, with 4 weeks of intervals following each course. For children, dose was reduced to 4 Gy or less once a day in every diseased region. Patients in the operation combined with application group were performed keloids excision first. Then 32P applicators were applied to the wound without any exudation in the same way as above. RESULTS: Of all the 39 patients (lesion thickness≤0.3 cm, 32P applicator therapy only), 32 ones was cured (82.1%), with the total effective rate of 98%. For patients with lesion thickness > 0.3 cm, the total effective rate of 32P applicator therapy and surgical excision combined with self-made 32P applicator were 55.6% and 93.3% respectively, and the difference was ofsignificance (P < 0.01 ). Among these patients, those with disease course less than 9 months had the effective rates of 25.0% and75.0% corresponding to 32P applicator therapy only and surgical excision combined with self-made 32p applicator respectively.For those with long course of disease, the effective rates were 13% and 77% respectively. A total of 26 patients experienced local buming and slight pain during the 32P applicator treatment, and all the symptoms were relieved by using calamine lotion; 5 patients and 2 patients expedencad grade Ⅰ and Ⅱ radio dermatitis respectively, which were relieved by using Mupirocin Ointment. No radio dermatitis of grade Ⅲ or above occurred to any patient. In addition, pigmentation or color changing occurred at local skins of cured patients.CONCLUSION: 32P applicator therapy is safe and effective for treating keloid. For patients with short disease course and lesion thickness ≤0.3 cm, 32P applicator therapy only is enough. Otherwise, patients are suggested to use 32P applicator after operation.

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 investigate the effect of IH764-3 on the leukocyte-mediated hypoxia-reoxygention injury of human brain microvascular endothelial cell (HBM VEC). Methods MTT assay was used to detect the survival of HBMVEC; gelatin zymography was used to check the activity of MMPs. The level of reactive oxygen species (ROS) in leukocyte was determined via commercially available kit, and the indirect enzyme-linked immunosorbent assay (ELISA) was used to quantify the contents of TNF-α, IL-1α, IL-2 and INF-γ in leukocyte culture medium. Results Survival of HBMVEC was impaired by hypoxia-reoxygenation, which was aggravated by supernatant of activated leukocytes but was attenuated by IH764-3. Leukocytes produced high level of MMP-9, ROS and cytokines (TNF-α, IL-1α, IL-2, IFN-γ) after hypoxia-reoxygenation, the process was inhibited by IH 764-3. Furthermore, IH764-3 could effectively reverse hypoxia-reoxygenation injury of HBMVEC with supernatant of activated leukocytes. Conclusion IH764-3 can protect HBMVEC from leukocyte-involved hypoxia-reoxygenation injury by attenuating the activation of leukocytes and inhibiting the pathogenic effects of leukocytes products.

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.
