OBJECTIVETo compare the clinical efficacy on knee osteoarthritis (KOA) at the early and middle stage between electroacupuncture (EA) and meloxicam.

METHODSNinety patients of KOA at the early and middle stage were randomized into an EA group and a meloxicam group, 45 cases in each one. In the EA group, EA was applied to Dubi (ST 35), Neixiyan (EX-LE 4), Liangqiu (ST 34), Heding (EX-LE 2), Xuehai (SP 10), Yan- glingquan (GB 34) and Zusanli (ST 36); the needles were retained for 20 min and EA was applied once every two days. In the meloxicam group, the meloxicam tablets were prescribed for oral administration, 7. 5 mg, once a day. The treatment lasted for 6 weeks in the two groups. The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score, rectus femoris muscle tension, the 8-foot walking test and 5-time sit-to-stand test were adopted to observe and compare the effects in the two groups.

RESULTSAfter treatment, every item score in WOMAC was reduced after treatment (all P < 0.05), but the difference was not significant between the two groups (all P > 0.05). In the EA group, the rectus femoris tension after treatment was reduced as compared with that before treatment (P < 0.05) and the reducing result was much more apparent as compared with that in the meloxicam group (P < 0.05). For the 8-foot walking test and 5-time sit-to-stand test, the time was shortened after treatment in the two groups (all P < 0.05) and the result in the EA group was much more obvious than that in the meloxicam group (both P < 0.05).

CONCLUSIONBoth EA and meloxicam are effective in the treatment of KOA at the early and middle stage. EA improves rectus femoris tension and recovers the internal mechanics balance and the efficacy is better than that of meloxicam.

BACKGROUND:Studies have shown that signaling pathway plays an important role in the pathogenesis of knee osteoarthritis. OBJECTIVE: To elaborate the experimental progress of signal transduction pathway in knee osteoarthritis METHODS: A computer-based retrieval of PubMed, CNKI, VIP and Wanfang databases was performed to find the relevant literatures concerning experimental studies of signaling pathway in knee osteoarthritis. Al data were primarily screened to exclude repeated and irrelevant articles. Articles about association between knee osteoarthritis and signal pathway were included.RESULTS AND CONCLUSION:A total of 51 articles were colected, including 20 in Chinese and 31 in English. It is concluded that the signal transduction pathway related to knee osteoarthritis is mainly concentrated in the two aspects: the proliferation of chondrocytes and the apoptosis of chondrocytes. The signal transduction pathways related to the proliferation of chondrocytes mainly include Notch signaling pathway and Wnt signaling pathway. SDF-1/CXCR4 signaling pathway, TLR4 signaling pathway, and MAPKs signaling pathway are associated with apoptosis in chondrocytes. Hippo-YAP signaling pathway and ERK1/2 signaling pathway have a double role in the regulation of proliferation and apoptosis of chondrocytes.

Objective:To investigate the effect of search for meaning on depression and the moderating role of perspective change in college students. Methods:The participants were 1 16 college students. The hypotheses were tested by analyzing data collected at 3 time points. Search for meaning and the presence of meaning in life were measured with the Meaning in Life Questionnaire,the dimension of perspective change in Meaning-Focused Coping Questionnaire was used to assess the ability to change perspective,and depression was assessed with the Center for Epidemiological Studies Depression Scale (CES-D). Results:The scores of perspective change was positively corre-lated with scores of meaning in life (r=0. 29 ,P<0. 0 1 ),and negatively correlated with CES-D scores (r=-0. 34,P<0. 001). The scores of perspective change moderated the relationship between scores of search for mean-ing and scores of presence of meaning in life (β=0. 22,P<0. 01 ),and this interaction effected CES-D scores through the mediation of scores of presence of meaning in life. That is,for the individuals with lower perspectivechange score (blow one standard),the score of search for meaning was negatively associated with the presence of meaning in life,with in turn increased CES-D scores,95%CI:0. 07 -033;among the individuals with higher per-spective change scores (above one standard),there was no mediation effect. Conclusion:The results suggest that perspective change could moderate the relationship between search for meaning and meaning in life,which in turn buffers depression. The findings imply the potential positive role of perspective change in the process of searching for meaning in life among university students.

Objective: The purpose of this research is to investigate the relationship between computer game addiction,a subtype of internet addiction,and parental Rearing styles.Methods: Using Computer Game Addiction Inventory(CGAI) and EMBU,we investigate a sample of 747 senior high school students in Beijing.According to whether participants' sum score of five dimensions of CGAI is larger than 1.5 SD,we divide them into two groups: tendency to addiction and non-tendency to addiction.Then we analyze the data with methods of MANOVA and Canonical Correlation.Results: There is significant difference in sex distributing between tendency to addiction and non-tendency to addiction.There is also significant difference in parental rearing styles between two groups.Under authoritarian rearing styles,children score higher on nearly every dimension of CGAI.Conclusion: Boys are more likely to get addicted to computer games than girls.Negative parental rearing styles associate closely with computer game addiction.

Objective To investigate the lymph node micrometastasis and its clinicopathologic features on 5-year disease free survival rate for patients with pT1-3N0 gastric cancer.Methods One hundred and twenty patients with stage pT1-3N0 gastric tumors were included,and 2 106 lymph nodes were harvested and examined in all the specimens.There were 9-28 lymph nodes with average 18 lymph nodes from each patient.All the lymph nodes were negative by HE staining.The CK20 expression of lymph nodes was tested by immunohistochemistry.The relationships between clinicopathologic features or CK positive expression and 5-year disease free survival were analyzed.Results The positive expression rate of CK20 was 9.07%(191/2 106)in lymph nodes and 26.67%(32/120)in patients with pT1-3N0 gastric cancer by immunohistochemistry.Eleven cases were with micriometastasis,21 cases were isolated tumor cells(ITC).The average postoperative follow-up was 66.35(range 24-121)months.Five-year disease free survival rates were 87.4%,78.3%,and 40.9% for the lymph node negative,ITC,and micrometastasis groups,respectively.Five-year disease free survival rate in the micrometastasis group was lower than that in the lymph node negative group(P=0.000)and ITC group(P=0.046).However,there was no significant difference between the lymph node negative group and ITC group(P=0.253).Multivariate analysis identified tumor diameter(P=0.011),depth of tumor invasion(P=0.043),and lymphatic vessel invasion(P=0.002)were related with CK20 positive expression.There was no significant relationship between the pathologic parameters and the 5-year disease free survival rates.Lymph node micrometastasis of gastric cancer was detected in 11 patients who should belong to stage pN1(Mi),the restage rate was 9.17%.While the lymph node negative(88 patients)and ITC(21 patients)were recorded pN0(i-)and pN0(i+),respectively,and were not recommended restage(stage pN0).Conclusion Patients with stage pT1-3N0 gastric cancer and micrometastasis in lymph node are with high-risk and low 5-year disease free survival rate,for whom adjuvant therapies may be justified and effective.

Objective To develop a novel padlock probe and rolling circle amplification(RCA) to detect 5 common cell culture contaminant Mollicute( Mycoplasma arginini, Mycoplasma fermentans, Mycoplasma hyorhinis, Mycomplasma orale, and Acholeplasma laidlawii ). Methods "Universal" primers ( SPS1, SPA2 and SPS2, SPA1) were used to amplify the Mollicute 16S-23S rRNA intergenic spacer region.Amplicon was ligate Mollicute specific padlock probe. Probe amplified and monitored using a Corbett RotorGeneTM 6000 machine. Results Five reference Mollicute strains were correctly detected by RCA method.There was no cross-reaction. RCA method can sensitive detect 10 copies templates and show strong positive signal. Sixty-two cell culture specimens were detected. Thirty-seven samples were contained single specie Mollicute and 14 samples contained two Mollicutes. Eleven samples did not contained Mollicute. RCA detection results were concordant with previously species-specific PCR. Conclusion RCA can rapid, sensitive and specific detect contamination Mollicute.

The parabrachial nucleus (PB)is made up of gray matter around the Pons combination(BC),mainly consisting of glutamatergic,GABAergic and enkephalinergic neurons.PB is connected to hypothalamus and basal forebrain through a network of nerve fibers.Specific lesion of the entire parabrachial complex in animals leads to a deep coma.PB also projects to the non-rapid eye movement(NREM)-related regions including the ven-trolateral preoptic,and receives the projections from the parafa-cial zone.Activation of the GABAergic neurons in parafacial zone can promote NREM sleep,which indicates that PB partici-pates in NREM sleep.Furthermore,the lateral PB is actived when rapid eye movement(REM)sleep is deprived.In conclu-sion,PB participates in regulating wakefulness, NREM and REM sleep.This review summarizes the advances in the roles of PB in sleep-wake regulation.
