Purpose:To compare the response and toxic reaction of 3-weeks’ and weekly taxotere/cisplation treatment in non-small-cell lung cancer. Methods:Group A: Taxotere 75mg/m~2 IV d 1,cisplatin 25mg/m~2 d 1-3 q3-4w; Group B: Taxotere 60 mg IV d1, taxotere 40 mg IV d8,d15, cisplatin 25 mg/m~2 IV d 1,d 8,d 15 q3-4w. The clinical responses were assessed after two cycles. Toxicity was assessed every cycle. Results:There was no CR in the 71 cases . There were 14 PR, 13 SD in group A; there were 16 PR, 14 SD in group B. The overall response rates were 41.2% and 44.4% in group A and B. The rates of grade Ⅲ/Ⅳ neatropenia were 70.6% and 25% in group A and B. The major nonhematologic toxicity was weakness. The rates of weakness were 44.1% and 19.4% in group A and B. Conclusions:The response rates were similar between groups A and B. The occurrence of hematologic toxicity and weakness were lower in weekly treatment.

Objective: To investigate target organ response by recording mean arterial blood pressure (MAP) fluctuation corresponding to nerve-tract discharges from the nerve innervating acupoint of Zusanli (ST 36) in the hind limb evoked by MA in anesthetized rats. Methods: Male SD rats anesthetized with chloral hydrate were randomly divided into 3 groups which were treated with manual acupuncture (MA), injection of lidocaine followed by MA and injection of normal saline (NS) followed by MA, respectively. The right carotid artery was canulated for persistent measurement of the blood pressure and meanwhile nerve discharges from the nerve-tract were recorded for analysis with amplitude spike counts for every 5 s. Results: The results showed that there were significant nerve discharges recorded from the nerve-tract when applying MA at Zusanli (ST 36) and simultaneous decrease in the MAP, while there was no response when inserting a needle into the Zusanli (ST 36) without manipulation (P<0.05). Furthermore, the reduction of MAP during MA could be completely abolished after blockade of peripheral nerve discharges with an injection of lidocaine into the tissue around Zusanli (ST 36) but not with that of normal saline (NS). Conclusion: These results indicate that MA at Zusanli (ST 36) can elicit the peripheral nerve discharges from the nerve innervating the acupoint; such kind of nerve discharges may contain acupuncture signal regulating blood pressure via somato-cardiovascular reflex.

Objective To evaluate the reliability and validity of a medication dependence questionnaire in mi?graineurs of the Chinese version. Methods One hundred fifteen migraine patients with drug dependence syndrome were included and their clinical data were then collected. All the subjects were interviewed with the medication dependence questionnaire in migraineurs of the Chinese version. The reliability and validity of the questionnaire were evaluated ac?cording to test-retest reliability and internal consistency reliability, and the content validity and construct validity respec?tively. Results The test-retest reliability of the questionnaire items was 0.725~1.000 except item 11 (0.558) and item16 (0.443). The internal consistency coefficient of the questionnaire was 0.820, internal consistency coefficient of each di?mension was above 0.7. Every item score was positively correlated with corresponding dimension score (r=0.595~0.962). Seven factors with latent roots greater than 1 could explain 76.3%of total variance, and these factors were relatively pow?erful in related items. Conclusions The medication dependence questionnaire in migraineurs of the Chinese version shows preferable reliability and validity. Thus, this is a promising assessment tool to evaluate the medication dependence in Chinese migraineurs in future clinical practice.

Objective: To clarify effect of electroacupuncture (EA) on relieving chronic visceral pain and the underlying neurobiological mechanism for such an effect, we observed the effect of EA on the Irritable bowel syndrome (IBS) rat and then examined spinal expression of N-methyl-D-aspartate (NMDA) receptor-1 in rats. Methods: Daily mechanical colon distention was performed on male Sprague-Dawley neonatal rats to produce IBS model. EA was applied at acupoints of Zusanli (ST 36) and Shangjuxu (ST 37) in each hind leg. Abdominal withdrawal reflex (AWR) assessment or rectus abdominis electromyograms (AEMG) recordings were then performed after EA treatment. The mRNA expression of the NMDA subtype of glutamate receptors in the spinal dorsal horn (L4-5) before and after EA was investigated by RT-PCR analysis in IBS rats. Results: The results demonstrated that EA could significantly decreased both AWR scores from behavioral test and AEMG discharges from electrophysiological recording in IBS model rats elicited by colorectal distension (CRD) stimuli with strengths of 20, 40, 60 and 80 mmHg, respectively (P<0.05). Meanwhile there was a significant decrease in mRNA expression of NMDA receptor-1 in the spinal dorsal horn of IBS rats treated by EA (P<0.05), but no such effect was observed in IBS rats treated by sham EA (inserting needles without electrical stimulation). Conclusion: These results indicate that EA can relieve chronic visceral hyperalgesia in IBS rats and this effect might be correlated with the down-regulation of NMDA receptor- 1 in the dorsal horn of the spinal cord.

Objective To verify the association between common breast cancer susceptibility loci which have been confirmed in European and Asian populations and breast cancer susceptibility in sporadic breast cancer among the Han nationality in Henan province , and to analyze their genotypes in the internal type of breast cancer . Methods In 253 breast cancer patients ( the case group ) and 343 patients who had benign breast lesions ( the control group), rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)were genotyped by SNP im-LDR technique.According to estrogen receptor(ER), progesterone receptor (PR), human epidermal growth factor receptor 2(HER2)and Ki67, breast cancer are divided into 5 types:Lu-minal A, Luminal B, HER2-enrich, Luminal HER2, and triple negative breast cancer ( TNBC).Results rs2046210(6q25.1), rs2981582(EGFR2), rs889312(MAP3K1)had no statistical differences between the case group and the control group(P=0.421, 0.459, and 0.468), but the genotype of rs3803662(TOX3/TNRC9)in the case group and the control group had statistical difference (P=0.037).The allelic frequencies of rs3803662 between the case group and control group were different in codominant inheritance ( OR=2.19, 95%CI:1.19-4.02)and recessive genetic models (OR =2.06,95% CI:1.15 -3.70).Compared with AA and GA, GG in-creased the risk of breast cancer ( P =0.012, 0.015 ).The genotypes of rs2046210 ( 6q25.1 ), rs2981582 (EGFR2), rs889312(MAP3K1), and rs3803662(TOX3/TNRC9)had no difference in different types of breast cancer.Conclusions Four common breast cancer susceptibility loci from GWAS are not entirely associated with breast cancer risk among the Han nationality in Henan province .Only rs3803662(TOX3/TNRC9)is confirmed to increase the risk of breast cancer .Different genotypes of 4 loci distribute equally in different types of breast cancer .

Abstract: Objective To observe the curative effect of thread-hanging combined with cotton plug on stage Ⅲ paronychia. Methods Sixty-one patients with stage Ⅲ paronychia were selected and randomly divided into a treatment group and a control group. The treatment group (n=31) was treated with thread-hanging and tampon under local infiltration anesthesia, and changed dressing and tampon every day after operation. After the wound healed, the patient soaked his feet in warm water every day and changed the tampon himself until the symptoms subsided, and the knot did not receive special treatment, and the nail plate would naturally shed as it outgrew the paronychia. The control group (n=30) was treated with thread-hanging and nail groove reconstruction under nerve block anesthesia, and the dressing was changed every day after operation. After thread removal, the patients soaked their feet in warm water every day until the symptoms subsided, and the knot was not specially treated, and it naturally fell off with the growth of the deck beyond the nail groove. The postoperative Visual Analog Scale (VAS) pain score, pain duration, wound healing time, cure rate, effective rate and recurrence rate of paronychia, and patients' satisfaction with the operation were compared between the two groups. Results Compared with the control group, the treatment group had lower VAS pain scores on the first and third postoperative days (2.1±0.3) and (0.2±0.1) vs. (6.3±0.1) and (3.2±0.2), respectively, shorter duration of pain and wound healing time (3.3±0.3) days and (10.1±0.5) days vs. (5.2±0.3) days and (15.2±0.3) days, respectively, higher cure rate (87.1% vs. 66.7%), lower failure rate (12.9% vs. 33.3%), lower recurrence rate (7.4% vs. 20.0%), and higher patient satisfaction (97.0% vs.75.3%). The treatment group showed significant superiority over the control group in all outcomes. Conclusion For patients with stage Ⅲ paronychia, thread-hanging combined with cotton tampon without nail groove reconstruction is advantageous as it avoids additional skin trauma, and does not affect the nail appearance and normal periungual barrier after healing, , reduces patient discomfort, and shortens the time off work, resulting in a higher cure rate. This treatment approach is therefore worth promoting in clinical practice.

Objective To evaluate the clinical efficacy and safety of combined ozone hydrotherapy for the treatment of atopic dermatitis(AD). Methods A total of 60 patients with moderate or severe AD aged from 6 to 65 years were enrolled, and randomly and equally divided into a test group and a control group. Both the two groups were treated with oral levocetirizine capsules 5 mg once a day, topical tacrolimus ointment twice a day, and topical moisturizers. The test group was additionally treated with ozone hydrotherapy 3- 5 times every week. The treatment lasted 2 weeks. The severity scoring of atopic dermatitis (SCORAD) score, visual analog scale (VAS) score, dermatology life quality index (DLQI) or children′s dermatology life quality index (CDLQI) score were assessed before and after the treatment, and compared between the two groups. Enzyme?linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin?4(IL?4)and nerve growth factor(NGF)in peripheral blood from the patients before and after the treatment. Results After 2?week treatment, the SCORAD scores, VAS scores and DLQI/CDLQI scores significantly decreased from 42.13 ± 16.03, 7.14 ± 2.12 and 14.92 ± 5.94 before the treatment to 27.3 ± 11.01, 2.23 ± 1.31 and 9.69 ± 4.17 respectively in the test group(all P<0.05), and from 43.36 ± 17.78, 6.45 ± 1.29 and 15.15 ± 5.40 to 39.65 ± 16.67, 3.32 ± 0.87 and 12.84 ± 5.37 respectively in the control group(all P<0.05). In addition, all the three scores were significantly lower in the test group than in the control group after 2?week treatment(all P<0.05). A significant decline was also observed in the levels of IL?4 and NGF in peripheral blood in the two groups at the end of the treatment compared with those at baseline(all P<0.05), and the magnitude of decline in IL?4 levels was significantly higher in the test group than in the control group(t=8.57, P<0.05), while that in NGF levels was insignificantly different between the two groups(t=9.51, P>0.05). Conclusion Combined ozone hydrotherapy can effectively and safely improve the condition of patients with AD, likely by decreasing the levels of IL?4 in peripheral blood.
