OBJECTIVETo explore a safe and effective scheme of analgesic for labor.
METHODSEighty-four primiparas without contraindication of vaginal delivery were divided into an observation group and a control group, 42 cases in each one. In the observation group, the acupoint injection was given at Zusanli (ST 36) combined with electroacupuncture (EA) at Hegu (LI 4) and Sanyinjiao (SP 6) till the cervical opening at the end of first stage labor. In the control group, the routine respiratory instruction was applied. In 5 min, 10 min and 60 min of acupuncture (the same time points in the control group) as well as at the end of the first and second stage labor, the analgesic effect was assessed for the primiparas of the two groups. The labor stages, adverse reactions, postpartum hemorrhage, postpartum urine retention, newborn asphyxia rate and usage rate of oxytocin were compared between the two groups.
RESULTSIn the observation group, in 5 min, 10 min and 60 min of acupuncture as well as at the end of the first and second stages, the visual analogue scale (VAS) was lower apparently as compared with the control group at the corresponding time points (all P < 0.05). The differences in the time limit in the active period, the second and third stages were not significant between the two groups (all P > 0.05). The incidence of adverse reactions and the usage rate of oxytocin were lower than those in the control group [2.4% (1/42) vs 31.0% (13/42); 2.4% (1/42) vs 23.8% (10/42), both P < 0.05]. The differences in postpartum hemorrhage, postpartum urine retention and newborn asphyxia rate were not significant between the two groups (all P > 0.05).
CONCLUSIONThe combination of acupoint injection and EA is the effective analgesic scheme for labor. This scheme effectively alleviates labor pain and has no maternal and child complications.

Chinese Journal of Information on Traditional Chinese Medicine 2017;24(2):65-69
Objective To investigate the effectsof quercetin on human umbilical vein endothelial cell (HUVEC)-12 undergoing endothelial-to-mesenchymal transition (EndMT) induced by TGF-β1; To discuss its mechanism of action. Methods Cell activity of intervening by quercetin with different concentrations and TGF-β1 for 72 h was detected by CCK-8 method;RT-PCR and immunofluorescence staining were used to detect the transition of endothelial and stromal markers; Western blot was used to detect the signal transduction pathway; RT-PCR was performed to detect the transcription factors that play crucial roles in the process of transformation. Results The results of RT-PCR and immunofluorescence double staining showed that TGF-β1 (10 ng/mL) stimulated HUVEC-12 cells for 72 h to induce fibroblast phenotype, showing more interstitial markers and less endothelial markers;Western blot and RT-PCR results showed that quercetin inhibited the phosphorylation of smad2/3 in a concentration-dependent manner;After TGF-β1 stimulation, the downstream transcription factors EndMT of snail1, twist1, twist2, ZEB1, and ZEB2 significantly increased, while 100 μmol/L quercetin could down-regulate the five downstream transcription factors. Conclusion Quercetin has anti-fibrosis effects through inhibiting HUVEC-12 cells undergoing EndMT.

Objective To evaluate four tumor markers of insulin-like growth factor 1((IGF-1), CEA, cytokeratin fragment antigen 21-1 (CYFRA21-1), neuron-specific enolase (NSE) for the diagnosis and prediction of treatment response in human lung cancer. Methods Serum samples were taken from three groups: 91 patients with lung cancer, 30 healthy adults and 15 patients with benign pulmonary diseases. Serum IGF-1 was assayed by radioimmunoassay and CEA, CYFRA21-1, and NSE by electrochemiluminescence immunoassay. The differences among the three groups were determined by Kruskal-Wallis one-way analysis of variance (ANOVA) and with Mann-Whitney rank-sum test. Diagnostic efficacy was evaluated by ROC curves. Results The four serum tumor marker levels were significantly higher in lung cancer group, as compared with the benign and the healthy (IGF-1:χ2=26.95,P<0.001, CEA:χ2=49.11,P<0.001; CYFRA21-1:χ2=40.63,P<0.001; NSE:χ2=14.76;P<0.001). The diagnostic sensitivities of IGF-1, CEA, CYFRA21-1 and NSE was 75.6% (34/45), 53.3% (24/45), 66.7% (30/45) and 42.2% (19/45) respectively for lung cancer. The diagnostic sensitivity of IGF-1 combined with CYFRA21-1 was 95.5 %( 43/45) and that of IGF-1 combined with CEA and CYFRA21-1was 97.8%(44/45). Only IGF-1 and CYFRA21-1 showed significant changes before and after treatment (IGF-1: χ2=5.99,P=0.014; CYFRA21-1:χ2=4.99, P=0.025) in cancer group. Conclusions Serum IGF-1, CEA, CYFRA21-1 and NSE are all valuable for lung cancer diagnosis and the combination of those parameters can enhance the diagnostic efficiency. Serum IGF-1 and CYFRA21-1 may also be useful for evaluating the treatment response in lung cancer.

OBJECTIVETo compare the protein profiles between decapeptide-treated and untreated planktonic cells of Streptococcus mutans (S. mutans) by differential proteomic analysis to determine and identify the key proteins.
METHODSIn our previous study, we investigated decapeptide (KKVVFKVKFK-NH2), which was a novel adenosine monophosphate. Compared with other oral pathogens tested, decapeptide had a preferential antibacterial activity against S. mutans. It also inhibited S. mutans biofilm formation and reduced the one-day developed biofilm. In the present study, we first synthesized decapeptide, and then compared the protein profiles between decapeptide-treated and untreated planktonic cells of S. mutans by two-dimensional gel electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. We also verified different expressions of key protein enolase in the protein level.
RESULTSThe results showed that decapeptide altered the protein expression of planktonic S. mutans. These proteins were functionally involved in carbohydrate degradation by glycolysis, protein folding, conjunction, transport, translation, adenosine triphosphate binding, protein binding, sequence-specific DNA binding, transcription factor activity, and two-component response regulator activity. Western blot results showed that enolase protein expression decreased obviously in decapeptide-treated cells of S. mutans.
CONCLUSIONThe protein expression of S. mutans significantly changed after synthetic antimicrobial decapeptide treatment, suggesting that decapeptide may present a preferential effect on oral caries by changing the expression of certain key proteins, such as enolase protein.

ObjectiveTo evaluate and compare the efficacy and adverse effects of recombinant human tumor necrosis factor receptor Ⅱ : IgG Fc protein for injection (etanercept) and methotrexate ( MTX )regimens for rheumatoid arthritis (RA). MethodsForty-six patients were randomly divided into two groups by stratified sampling method:etanercept group,22 patients were treated with 12.5 mg of etanercept,twice times per week by subcutaneous injection;and MTX group,24 patients were treated with 5-10 mg of MTX,once per week by oral administration. The course of treatment lasted 24 weeks in both groups, so as to observe their ACR20, ACR50, ACR70 and adverse effects of the drugs. ResultsAfter treated for 24 weeks,ACR50,ACR70 respectively achieved 54.5% (12/22),31.8% (7/22) in etanercept group,which were significantly higher than those in MTX group[16.7%(4/24),4.2%( 1/24)]. The total efficacy was 86.4% (19/22) in etanercept group, 20.8% (5/24) in MTX group, the difference between the two groups was significant (P < 0.05 ). The incidence of adverse effects was not significant between the two groups [22.7%(5/22) vs. 50.0% (12/24)](P > 0.05). ConclusionEtanercept has a good efficacy and safety for the treatment of active RA.

Background and purpose:The traditional 3 incision surgery is an important means of esophageal cancer treatment, however, accompanied by more postoperative complications and higher mortality. Minimally invasive esophagectomy is a prospective technology with advantages, such as little trauma and quick recovery. This study retrospectively analyzed the perioperative effect of the esophagus cancer patients who accepted thoracoscopic-laparoscopic esophagectomy (TLE), open-laparoscopic esophagectomy (OLE) and open esophagectomy (OE) from Jan. 2013 to Jan. 2015. Methods:In this study, 72 patients received TLE, 76 patients received OLE and 115 patients received OE, respectively. One-way ANOVA, Kruskal Wallis test and Chi-square test were used to compare the differences of general clinical data, perioperative recover index, the number of lymphadenectomy and the postoperative complication among TLE, OLE and OE. Results:There were differences in the area of operative blood loss, duration of ICU stay and first standing time among the 3 groups. Pairwise comparison demonstrated that TLE group was signiifcantly better than OE group (P<0.012 5). The total number of lymphadenectomy among the 3 groups had no differences. However, the number of lymph node of the upper esophagus in the TLE groups was more than those in OLE group and OE group (P<0.001). The laryngeal recurrent nerve injury incidence in TLE group was signiifcantly higher than those in OLE group and OE group (P=0.012, 0.003). The total surgical complication had no differences among 3 groups. In areas of the cardiorespiratory system severe complication, 3 groups had statistical differences. Pairwise comparison showed TLE group was significantly less than OLE and OE group (P<0.0125). The first day and third day incidences of SIRS rate in TLE group were less than those in OLE group and OE group (P<0.0125). Conclusion:Comparing to OE group, with the same safety and feasibility, TLE had more advantages such as trauma, quick recovery, less complications. With the same effect of total lymphadenectomy to OE, TLE had the more advantage in upper mediastinal and recurrent laryngeal nerve lymph node cleaning.
