Objective To observe the therapeutic effect of Jiaji point needling for the treatment of gastroesophageal reflux disease (GRD) with liver-stomach stagnated heat type. Methods Sixty GRD patients were randomly divided into Jiaji point group and conventional point group, 30 cases in each group. Jiaji point group was given needling on bilateral T5 to T10 Jiaji points, and conventional point group was given acupuncture mainly on Zusanli, Zhongwan and Neiguan points, once a day for 10 continuous days. Before and after treatment, the scores of clinical symptoms and gastroscopy results were observed, and then the therapeutic effect and recurrence rate of GRD were evaluated. Results (1) The total effective rate of Jiaji point group was 86.7％, and that of the conventional point group was 83.3％, the difference being insignificant (P > 0.05). (2) After treatment, the scores of clinical symptoms of the two groups were decreased (P < 0.01 compared with those before treatment), and the decrease in Jiaji point group was superior to that in the conventional point group (P < 0.05). (3) After treatment, the mean R value of gastroscopy results in the two groups was lower than that before treatment (P <0.01) , but the difference of the mean R value of gastroscopy results in the two groups was insignificant (P >0.05). (4) After treatment for 2 months, the recurrence rate of Jiaji point group was 23.5％ and that of the conventional point group was 42.9％, the difference being insignificant between the two groups (P > 0.05).Conclusion The short-term effect of Jiaji point needling for the treatment of GRD with liver-stomach stagnated heat type is superior to that of conventional point needling.

BACKGROUND: The transcription factor, hypoxia-inducible factor-1al pha (HIF-1α), is the key regulator that controls the hypoxic response of mammalian cells. However, the role of HIF-1α in the therapeutic efficacy of chemo-radiotherapy in oral squamous cell carcinomas (OSC) is poorly understood. OBJECTIVE: To investigate the effect of HIF-α on the susceptibility of OSC cell lines against chemotherapeutic drugs and radiation. DESIGN: AN observational comparative experiment. SETTING: Beijing Chaoyang Hospital Affiliated to Capital Medical University. MATERIALS: OSC-2, OSC-4, OSC-5, and OSC-6 cell lines were estab lished from oral squamous cell carcinoma (The cell lines were from the De partment of Oral Oncology, Kochi Medical School, Japan). METHODS: The experiments were completed in Beijing Chaoyang Hospi tal affiliated to Capital Medical University from September 2004 to August 2006. The cells were cultured in Dulbecco's modified Eagle's medium (DMEM) containing fetal bovine serum (FBS), L-glutamine, penicillin and streptomycin. ① Total cell lysates were extracted from untreated OSC cells and those treated with 30 Gy γ-rays, 100 μmol/L cis-dichlorodiamine plat inum (CDDP), or 100 μmol/L 5-fluorouracil (5-FU). The expressions of HIF-1α protein and mRNA were determined with western blotting analysis and real-time polymerase chain reaction (PCR). ② Inhibition of cell prolif eration after different interventions: OSC cells were seeded in 96-well mi croplates (1.0×104) and cultured for 48 hours after the irradiation with 30 Gy γ-rays or in the presence of 100 μmol/L CDDP or 100 mmol/L 5-FU, and then the inhibition of cell proliferation was detected with 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. ③ Apoptosis after different interventions: OSC cell lines were cultured for 24 hours after the irradiation with 30 Gy γ-rays or in the presence of 100 μmol/L CDDP or 100 μmol/L 5-FU. The cells were then stained with annexin V-FITC and propidium iodide, and the numbers of apoptotic cells were analyzed by a FACScan cytometer (only for the OSC cells treated with γ-rays and CDDP). ④ Plasmid construction and transfection: Human HIF 1α cDNA was cloned into the pcDNA3.1/V5-His TOPO expression vector. OSC-2 cells were temporarily transfected with HIF-1α cDNA. OSC-5 cells were temporarily transfected with HIF-1α siRNA (Sense sequence is 5' CUGAUGACCAGCAACUUGAtt 3'). The blank control group was also set, the inhibition of cell proliferation was observed, and the apoptosis was ana lyzed (only in the CDDP-treated group) by using the methods mentioned above. MAIN OUTCOME MEASURES: ① Expressions of HIF-1α protein and mRNA in different OSC cell lines; ② Inhibition of proliferation and the apoptosis of OSC cell lines after different interventions; ③ Overexpression and knockdown of HIF-1α by expression vector and siRNA; ④ Influence of overexpression and knockdown of HIF-1α on the susceptibility of OSC cell lines against γ-rays and chemotherapeutic drugs. RESULTS: ① Expressions of HIF-1α protein and mRNA in different OSC cell lines: The relative expression levels of HIF-1α mRNA were 1.0, 2.2, 4.3 and 4.0 in OSC-2, OSC-4, OSC-5 and OSC-6 cells, respectively. Simi larly, the expression of HIF-1α total cell lysates proteins and nuclear proteins were much lower in OSC-2 and OSC-4 cells than in OSC-5 and OSC6 cells. ② Inhibition of proliferation and the apoptosis in OSC cell lines after different interventions: After the treatment with g-rays, CDDP, and 5-FU, the cell numbers decreased obviously to (39.5±3.2)%, (39.2±1.2)%,and(47.9±3.6)% in OSC-2 cells, (53.9±6.6)%, (54.3±1.4)%, (54.8±3.8)%in OSC-4 cells. Those decreased to (74.1±3.8)%, (76.5±9.1)%, (69.6±7.7)%in OSC-5 cells and (71.4±7.4)%, (84.4±8.8)%, (82.0±4.5)% in OSC-6 cells.After the OSC cells were treated of with CDDP, the numbers of apoptotic cells were (50.9±1.3)%, (67.3±2.2)%, (12.2±0.8)% and (38.6±0.9)% in OSC-2, OSC-4, OSC-5 and OSC-6 cells. G-rays induced the apoptosis were (21.2±1.1)%, (14.6±0.9)%, (9.7±1.0)% and (10.4±0.8)% in OSC-2, OSC-4,OSC-5 and OSC-6 cells. ③ Inhibition of proliferation and the apoptosis in the transfected cell after different interventions: The cell numbers of HIF-1 α-transfected OSC-2 cells treated with γ-rays, CDDP and 5-FU were much more than those in the control group (t=-4.693 ,-8.617,-6.721, P ＜ 0.01),whereas the cell numbers of OSC-5 cells transfected with siRNA were obviously fewer than those in the control group (t=5.800, 5.595, 4.253, P ＜ 0.05-0.01). After the incubation of HIF-1α-transfected OSC-2 cells with CDDP for 24 hours, apoptosis was detected in (34.0±1.9)% of the cells, which was lower than that in the control group [(49.6±3.4)%, t=6.937, P ＜ 0.01]. After the incubation of HIF-1α siRNA transfected OSC-5 cells with CDDP for 24hours, apoptosis was detected in (27.7±2.3)% of the HIF-1α siRNA transfected OSC-5 cells, which was obviously higher than that in the blank control group [(11.4±2.1)%, t=-8.941, P ＜ 0.01].CONCLUSION: The expression level of HIF-1α correlates negatively with the susceptibility of OSC cells against chemotherapeutic drugs and radiation. The down-regulation of HIF-1α expression enhances the susceptibility of OSC cells against chemotherapeutic drugs and radiation. Therefore, the down-regulation of HIF-1α may be a potentially effective strategy for cancer treatment.

砄bjective: To evaluate the diagnostic significance of exfoliative cytological examination and micronucleus assay. Methods: 26 cases of leukoplasia (LK) and 18 cases of oral squamous cell carcinoma (SCC) were examined. Cells were scrapped from the lesions, stained with Papaniceolaou. The keratinization types and the configuration of the cells were studied. Smears were also stained using the Feulgen plus fast green method. The frequency of micronucleated cells was counted. Results: Mixed keratinization was observed in all 15 cases of LK without dysplasia and in 7 out of 11 cases of LK with dysplasia. Parakeratosis was found in 17 out of 18 cases of SCC. There was a significant difference of cell keratinization types and cytologic diagnosis between the cases of LK and SCC( P 0.05).Conclusion: Parakeratosis in oral exfoliative cells may indicate a high risk of malignance.

Objective To analyze the changes in nutritional status changes of pediatric acute lymphoblastic leukemia (ALL) patients before and after chemotherapy and to evaluate the effects of enteral nutritional support on the states of nutrition and complication of chemotherapy.Methods Sixty-two newly diagnosed ALL patients from Novem-ber 2012 to December 2013 in Center of Hematology,Beijing Children's Hospital Affiliated to Capital Medical University were enrolled in this study.Patients were randomly assigned into an intervention group and a control group.During the induction and the early consolidation chemotherapy,the control group was given routine low fat diet routinely,and the intervention group was given Nestle peptamen [20 mL/(kg · d)] as the enteral nutritional support,meanwhile the routine low fat diet was also given.Changes in the nutritional status before and after chemotherapy and effectiveness of nutritional complementary therapy for preventing the chemotherapy complications were analyzed.Results (1) Basic information:there was no significant difference in age,gender,risk group,anthropometry,albumin and pre-albumin level between 2 groups before chemotherapy.(2)Nutritional status:the rate of malnutrition was 11.3 ％,and skinniness cases under 5 years of age occupied 10.0％.In the control group,the Z scores of W/H (weight-for-length/height,t =3.160,P =0.040),the Z scores of BMI (body mass index,t =3.490,P =0.010) and the albumin level(t =-1.805,P ＜0.001) decreased after chemotherapy,and the difference was statistically significant.On the other hand,the Z scores of W/H and BMI kept stable after chemotherapy in the intervention group,the albumin level raised from (40.53 ±3.96) g/L to (44.36 ± 3.31) g/L (t =-4.500,P ＜ 0.001) and the pre-albumin level raised from (126.55 ± 39.28) g/L to (189.55 ± 51.81) g/L(t =2.710,P =0.010),which was of statistical difference.The albumin level(t =5.020,P ＜ 0.001),pre-albumin level (t =3.036,P =0.040) and the Z scores of W/H (t =2.790,P =0.010),BMI (t =3.370,P ＜ 0.001),weight for age (W/A,t =2.830,P =0.010) were all higher in the intervention group,and the differences in statistical significance were found.(3)Side effects of chemotherapy:patients in the intervention group had higher hemoglobin (t =2.070,P =0.043) and platelet (Z =-2.19,P =0.033) level during the chemotherapy which induce less platelet [(0.50 ± 1.00) U vs (2.00 ± 2.00) U ; Z =-3.53,P =0.003] and red blood cells [(3.87 ± 2.01) U vs (5.25 ± 1.87) U ;t =-2.810,P =0.007] transfusion.Period of neutrophil deficiency [(15.67 ± 8.85)d vs (25.94 ±8.72) d;t =-4.601,P ＜0.001]was also shorter than that in the control group.Other complications had no difference between two groups exclude mild liver function abnormality was found more in the controls(x2 =6.680,P =0.010).(4)Safety:the complete remission rate 15 days after chemotherapy was 83.3％ in the intervention group and 81.2％ in the control group (x2 =0.046,P =0.830).All patients got complete remission on day 33.There was no significant difference.No pancreatitis happened in both groups during the chemotherapy.Conclusions Malnutrition rate is high among newly diagnosed ALL pediatric patients,and the nutritional status will deteriorate during the chemotherapy.Enteral nutritional support contributes to maintaining the stability of nutritional status.Enteral nutritional support improves the tolerance of hematopoietic system to chemotherapy.The effect for other complications remains to be confirmed by more extensive study in future.Nestle peptamenas enteral nutritional support productions are safe for ALL patients undergoing chemotherapy.

With the development of modern society,children get more and more attention from their parents.However,this situation often leads to parents' overprotection during their child-raising,especially when they have a child with pediatric diseases.Parents' inappropriate parenting may even affect the prognosis and outcome of their children's disease.According to recent studies about parenting of pediatric disease children,the parents would inevitably take overprotection,which might affect children's physical and mental health.Therefore,It is recommended that parents should correctly understand the diseases and their children,and choose appropriate parenting.
