Objective To explore the effect of Jin's three-needle therapy, as an assistant treatment, in improving the intelligence of children with mental retardation (MR).Method Seventy-six MR patients were divided into a control group and an observationgroup, 38 cases in each group.The control group was treated with rehabilitation, while the observation group with JIN's three needle therapy plus the rehabilitation training.Prof. JIN Rui's 10-item observation index was adopted to evaluate the memory ofthe patients before and after the treatment; Gesell Developmental Schedule (GDS) was used to measure the intelligence before and after the treatment. The clinical efficacies in the two groups were statistically analyzed.Result After the treatment, Prof.JIN Rui's 10-item index scores dropped obviously and the GDS scores increased significantly in both groups, while the decrease and increase of scores in the observation group were more significant than those in the control group (P<0.05). The total effective rate was 94.7% in the observation group, significantly higher than 71.1% in the control group (P<0.05).Conclusion As an assistant treatment, JIN's three-needle therapy can help rehabilitation training to improve the intelligence of MR patients.

BACKGROUND:5-Fluorouracil is a common chemotherapy drug for gastric cancer, but it is more likely to develop drug resistance in clinical treatment. Studies have shown that tumor stem cels are lowly sensitive to chemotherapeutic drugs, which may be an important cause of chemotherapy resistance. OBJECTIVE:To analyze the sensitivity of gastric cancer stem cels to 5-fluorouracil in vitro, and to understand the mechanism of drug resistance associated with gastric cancer. METHODS:Based on the sorting strategy, human gastric cancer cel clones were isolated from AGS cel lines. CD44 and thymidylate synthetase expression in different clones was detected using immunocytochemistry analysis. Clone formation assay was used to evaluate self-renewal capacity of different clones. Cel counting kit-8 was used to determine the clonal growth inhibition rate of AGS under treatment with different concentrations of 5-fluorouracil. RESULTS AND CONCLUSION:The AGS cels that were inoculated with low density and cultured could differentiate into 32 forms, including the ful clone (16%, 5/32), the second clone (66%, 21/32) and the accessory clone (19%, 6/32). Among them, the ful clones highly expressed CD44 and thymidylate synthetase, and could generate a great amount of passage 2 clones after inoculation; the second clones showed a weak expression of CD44 and thymidylate synthetase, and could generate a smal number of passage 2 clones after inoculation; the accessory clones showed a weak or no expression of CD44 and thymidylate synthetase, and there was no passage 2 clone after inoculation. Under the effect of different concentrations of 5-fluorouracil, the growth inhibition rates of the secondary clones and AGS cels were both higher than that of the ful clones (bothP < 0.05). These findings indicate that gastric cancer stem cels have a relatively lower sensitivity to 5-fluorouracilin vitro, which is speculated to be an important mechanism of drug resistance.

Objectives To observe the effect of Jianpi-Huayu decoction for preventing the patients from the recurrence of colonic adenoma after endoscopic mucosal resection. Methods A total of 60 patients with colonic adenoma who received endoscopic mucosal resection were divided randomly into the experimental group (taking Jianpi-Huayu decoction) and the controlled group (taking nothing as treatment), 30 patients in each group. Both groups were treated for 1 year. After 1 year, colonscopy was taken, and the number and size of colonic adenoma were recorded. The expression of COX-2, Ki67 in the colonic mucosa were detected the immunohistochemistry, and the negative rate of COX-2, Ki67 were also detected. Results After the treatment, the number (0.20 ± 0.48 vs. 1.67 ± 1.54, t=4.980) and size (0.23 ± 0.57 vs. 2.73 ± 2.80, t=4.788) of colonic adenoma in the experimental group were statistically lower than those in the ontrolled group (P<0.01);the expression of COX-2 (1.96 ± 1.27 vs. 3.64 ± 1.95, t=3.673) and Ki67 (2.04 ± 1.46 vs. 4.50 ± 1.73, t=5.558) in the the experimental group were statistically lower than those in the ontrolled group (P<0.01). The number of the paitents whose COX-2, Ki67 negative rates in the experimental group were 21 and 22, and the control group were 12(P=0.004) and 14 (P<0.001), which showed the significant difference between two groups. Conclusions The Jianpi-Huayu decoction could reduce recurrence of colonic adenoma after endoscopic mucosal resection, the mechanism was decreasing the expression of COX-2, Ki67 in colonic mucosa.

Objective To investigate the resilience of primary caregivers of cancer patients undergoing chemotherapy and explore the influencing factors. Methods General information questionnaire and Cornor-Davidson resilience scale (CD-RISC) were used in the survey among 173 cancer patients undergoing chemotherapy as well as their primary caregivers. Results The score of resilience of primary caregivers was (70.76 ±13.34), at middle or above level. Multiple linear regression analysis showed that caregivers'resilience was affected by gender, age, family income and religious belief (all P<0.05). Conclusion The resilience among primary caregivers of cancer patients undergoing chemotherapy is at a relatively high level. Clinically, we should pay more attention to female and young patients with lower family income and no religious beliefs.

Objective To explore the pharmaceutical care approaches for patients with lung cancer complicated with renal insufficiency receiving pemetrexed chemotherapy. Methods An elderly patient with lung cancer complicated with renal insufficiency receiving pemetrexed chemotherapy faced inevitable safety risks.Clinical pharmacists considered it as an intervention point, and provided individual pharmaceutical care. Results Clinical pharmacists fully assessed the safety risks of the case receiving pemetrexed chemotherapy with clinicians, assisted in improving the therapeutic regimen, and carried out medication education for the patient. No serious adverse drug reactions occurred in the patient, and anti-tumor efficacy was obtained. Conclusion For patients of lung cancer complicated with renal insufficiency receiving pemetrexed chemotherapy, clinical pharmacists should focus on creatinine clearance rate, and decide whether the combined use of platinum anti-tumor drugs, non steroidal anti-inflammatory drugs and zoledronic acid can be adopted, and follow-up on adverse drug reactions and anti-tumor efficacy.

Objective To investigate the method of handmade microwire lasso device for the management of coil migration during intracranial aneurysm embolization. Methods Two migration coils were removed from intracranial arteries using handmade microwire lasso rings. The first coil prolapsed completely from an aneurysm sac and flowed to the middle cerebral artery M2 segment. The second coil partially prolapsed out into a parent artery. The microwire lasso device was made of 4-0 silk thread and fixed using 0. 36 mm (0. 014 inch)microwire and 0. 43 mm (0. 017 inch)microcatheter. Results After removing 2 migration coils from intracranial arteries,angiography did not reveal vascular injury and thrombosis. There was no aneurysm rupture. After awaking from anesthesia,the patient did not have neurological deficit. The patient was followed up for 3 months after procedure. MR angiography confirmed the patency of related arteries. Conclusion The handmade microwire lasso device for the management of coil migration in the process of aneurysm embolization is a simple,effective,and economical method.

Objective To investigate the influencing factors for late-preterm birth of twins. Methods We retrospectively analyzed the clinical data of 301 twins delivered in Beijing Haidian Maternity and Child Health Hospital between August 1, 2011 and August 31, 2013. Twins with late-preterm births were classified as the observation group(n=138) and those delivered at term were classified as the control group (n=163). Comparison between the two groups was conducted on both maternal and neonatal complications. Two independent sample Student's t test, Chi-square test and logistic regression analysis were performed for statistical analysis. Results (1) The ratio of two male fetuses, dichorionic diamniotic twins, and iatrogenic preterm birth were 41.3% (57/138), 76.1% (105/138) and 65.2% (90/138), respectively, in the observation group, while 23.9% (39/163), 89.6% (146/163) and 96.9% (158/163), respectively, in the control group (χ2=10.40, 9.81 and 53.59, respectively, all P<0.05). Mean birth weight of twins in the observation group was less than that in the control group [(2 450±349) vs (2 640±304) g, t=7.12, P<0.05]. Maternal age, gravidity, parity, history of abortion, mode of conception and 1 min Apgar score of the neonates between the two groups were not significantly different (all P>0.05). (2) The risk factors for late-preterm birth of twins included hypertension diseases complicated pregnancy, gestational diabetes mellitus, premature rupture of membranes, fetal distress, anemia and umbilical cord abnormality [OR=0.190(95%CI: 0.094-0.387), 1.980 (95%CI: 1.009-3.883), 0.030(95%CI: 0.007-0.131), 0.062(95%CI: 0.006-0.642), 0.470(95%CI:0.243-0.908) and 2.779(95%CI:1.093-20.736), respectively, all P<0.01 or 0.05]. (3) The incidences of hyperbilirubinemia, respiratory diseases, hypoglycemia, anemia, and neonatal infection were 27.9%(77/276), 4.4%(12/276), 4.7%(13/276), 4.4%(12/276) and 3.6%(10/276), respectively, in the observation group, which were all higher than those in the control group [9.5%(31/326), 0.6%(2/326), 1.2%(4/326), 0.6%(2/326) and 0.3%(1/326), respectively,χ2=34.33, 9.18, 6.61, 9.18 and 9.16, respectively, all P<0.05]. The incidence of small for gestational age in the observation group was lower than that in the control group [3.6%(10/276) vs 12.3%(40/326),χ2=3.86, P<0.05]. Other complications in the two groups (intracranial hemorrhage, acidosis, and hemolysis) were not significantly different (all P>0.05). Conclusions Late-premature births in twin pregnancies are related to many maternal and fetal risk factors. Therefore, clear understanding of these risk factors might improve the pregnancy outcomes.
