Objective:To observe the clinical efficacy of warm needling plus acupoint sticking therapy for primary dysmenorrhea.
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) according to their sequence of consultation. Patients in the treatment group were treated with warm needling combined with acupoint sticking therapy, whereas patients in the control group were treated with oral Ibuprofen (Fenbid) capsules. After two menstrual cycles, the visual analogue scale (VAS) score, COX menstrual symptom scale (CMSS) and clinical efficacy were compared between the two groups.
Results:After treatment, the VAS and CMSS scores were significantly reduced in both groups, indicating that both treatment protocols can remarkably alleviate pain. There was a between-group statistical difference in comparing the CMSS score (P<0.05), but no between-group statistical difference in the VAS score (P>0.05). However, the follow-up visit showed between-group statistical differences in comparing VOA and CMSS scores (bothP<0.01). The clinical effect, relapse rate and long-term efficacy in the treatment group were better than those in the control group.
Conclusion:Warm needling plus acupoint sticking therapy is a simple but effective therapy for primary dysmenorrhea. In addition, it causes fewer cases with relapse.

ObjectiveTo investigate the relationship between metastasis-associated gene 1 ( MTA1 )expression and invasive and metastatic ability of cervical cancer cell. MethodsThree kinds of plasmids pcDNA3( control group), pcDNA3-MTA1 ( MTA1 group) and pSilencer3. 1-MTA1-siRNA ( MTA1-siRNAgroup) were transfected into human cervical cancer cell line CaSki cells. Reverse transcription (RT)-PCR and western blot were used to detected MTA1 mRNA and protein expressions. The effects of MTA1 expression on CaSki cell growth and proliferation, cell migration, adhesion and invasion, and cell cycles were tested by methyl thiazolyl tetrazolium (MTT), clone formation experiment, wound-healing assay, transwell assay, adhesion assay and flow cytometry, respectively. In animal experiment, three groups of cells were inoculated to BALB/c nude mouse subcutaneously to observe tumor formation ability. ResultsCompared with control group, MTA1 mRNA and protein were significantly overexpressed in MTA1 group, while MTA1-siRNA group showed lower MTA1 expression. Compared with control group, MTA1 group showed significantly accelerated cell growth; while MTA1-siRNA group showed decreased cell growth since the second day (P＜0. 05). Clone formation number in control, MTA1 and MTA1-siRNA group were 133 ±6, 169 ± 10 and 57 ±5,respectively. MTA1 group showed accelerated cell formation, while MTA1-siRNA group showed the reverse effect compared with that in control group(P ＜ 0. 05 ). At 24, 48 and 72 hours after wounding, the healing ability of MTA1-siRNA group significantly lagged behind that in the control group, while MTA1 group showed accelerated cell healing ability. The adhesion rate of control, MTA1 and MTA1-siRNA group were (69. 3 ± 3. 6) ％, ( 80. 4 ± 5. 6 ) ％ and ( 39. 2 ± 7.4 ) ％ separately at 90 minutes after cell seeding. In contrast with control group, MTA1 group promoted the adhesion of CaSki cell to matrigel matrix, while MTA1-siRNA group inhibited the adhesion process (P ＜0. 05 ). In the migration assay, the number of cells migrated to the bottom side of the membrane in control,MTA1 and MTA1-siRNA group were 153 ± 17,247 ± 38 and 82 ± 10, respectively. The number of cells in the invasion assay were 231 ± 19,354 ± 36 and 76 ± 7, respectively. Compared with the control group, MTA1 group significantly increased the migration and invasion ability, while MTA 1-siRNA group showed lower cell migration and invasion ability (P ＜ 0. 05 ). In cell cycle experiment, no significant differences of cell proportions including G1, S and G2 stage were found among three groups (P ＞ 0.05).In animal experiment, compared with control group,MTA1 group showed accelersted tumor formation and growth,whilethe MTA1-siRNA group showed the reverse effect ( P ＜ 0. 05 ). ConclusionsMTA1 may play its roles to promote cervical cancer cell invasion, migration, adhesion, as well as cell growth and colony formation, while RNA interference against MTA1 may decrease the malignant phenotypes. This study shows that it will be an effective beginning to explore metastasis mechanisms and cancer gene therapy strategy targeting MTA1 in cervical cancer.

Objective To investigate the role of Rho/Rock signaling pathways in ventilator-in-duced lung injury in rats.Methods Ninety-six male SD rats,weighing 300-350 g,were equally and randomly divided into four groups using a random number table (n =24 each):control group (group C),fasudil group (group F),high tidal volume group (group H)and high tidal volume + fasudil group (group HF).Rats in group C and group F received no mechanical ventilation,rats in group H and group HF were intubated and mechanically ventilated (VT = 40 ml/kg,RR = 40 beats per minutes,FiO 2 =40%)for 4 h.The animals in group F and group HF were given intraperitoneal in-jection of fasudil 10 mg/kg at the time 1 h before mechanically ventilated.Six rats were chosen in each group at the time before ventilation (T0 )and at 4,8,24 h after ventilation (T1-T3 ),and blood sam-ples were taken for determination of the levels of serum tumor necrosis factor-α (TNF-α),IL-6 and IL-10,lungs were removed,bronchoalveolar lavage fluid (BALF)was collected to examine protein content,wet/drying (W/D)ratio was determined,which were then stained with haematoxylin and e-osin and examined under microscope,the pathological changes of lungs were scored.Myeloperoxidase (MPO)activity in lung tissue was determined by spectrophptometry.Protein and gene expression of RhoA and Rock2 in the lung tissue were detected by Western blot and reverse transcription PCR (RT-PCR).Results Compared with group C,the serum TNF-α,IL-6 and IL-10,BALF protein content, W/D ratio,the pathological scores,MPO activity,the expression of RhoA,Rock2 protein and mR-NA were significantly increased in group H and HF at T1-T3 (P <0.05 ).Compared with group H, the serum TNF-αand IL-6,BALF protein content,W/D ratio,the pathological scores,MPO activi-ty,the expression of RhoA,Rock2 protein and mRNA were significantly decreased,and the serum IL-10 was significantly increased in group HF at T1-T3 (P <0.05).Conclusion Fasudil can attenuate ventilator-induced lung injury in rats,and the mechanism may be associated with inhibition of the Rho/Rock signaling pathways reducing the inflammatory response.

This article reports one hepatic echinococcosis patient complicated with systemic sclerosis. His clinical manifesta?tions were the progressive fibrosis of the skin,sour regurgitation,and belching. The blood examination showed that eosinophils was reduced,and antinuclear antibody(ANA)was positive at 1∶100 in cytoplasm particle type. He was given prednisone ace?tate 25 mg,q. d.,aspirin 100 mg,q. d.,centella triterpenes cream 12 mg t. i. d.,esomeprazole 40 mg q. d.,and domperidone 10 mg t. i. d. After one week,the Rodnan skin score reduced from 27 to 17. The liver hydatid cyst resection was performed,and the follow?up showed that his clinical manifestations improved and the Rodnan skin score reduced further.

To investigate the protection effect of DNA vaccine in mammalian and avian systems, the DNA vaccine was inoculated in both BALB/c mice and SPF chickens immunized with DNA vaccines encoding hemagglutinin (HA) from A/Goose/GuangDong/1/96 (H5N1) virus. The mice and chickens were immunized twice, 3 weeks apart, by electroporation into muscles or intramuscular injection. Two weeks after the second immunization, the mice and chickens were challenged with a lethal dose of homologous virus. The mice and chickens immunized by electroporation obtained completely protection against the virus, and could effectively inhibited viruses to replicating in mouse lung and chicken cloaca. At the same time, these protections were companied by high levels specific antibody to H5N1 AIV, while the blank plasmid controls experience 100 percent mortality following challenge. Furthermore, in the experiment of mice by eletroporation,stronger obviously CTL activity were observed after challenge. Thus, the cellular immune responses of the mice immunized by electroporation were exhibited. These results strongly demonstrate that HA DNA vaccines provide effective protection against influenza virus infection in mammalian and avian, and suggest that electroporation is one of the efficient gene delivery systems for the transfer of influenza DNA vaccine in both humoral immunity and cellular immunity.

Objective To explore the association of C20orf54 gene rs3746804 position single nucleotide polymorphism and susceptibility to esophageal squamous cell carcinoma (ESCC).Methods Purification of genomic DNA from whole blood was used the Maxwell(R) 16 System.rs3746804 in C20ort54 was detected by direct sequencing in 434 ESCC patients from Changzhi (Shanxi province) and Linzhou (Henan province) and 554 healthy controls from Changzhi,Linzhou and including immigrators from Linzhou to Changzhi.Results For rs3746804,the genotypic frequencies of CT(37.5％ vs 51.0％,37.5％ vs 52.0％),CC (44.2％ vs 34.8％,44.2％ vs 33.0％) in Changzhi ESCC patients showed significant differences with healthy Changzhi controls and the healthy immigrator controls (all P ＜ 0.05),and the frequencies of TT(18.3％ vs 4.1％) and CC (44.2％ vs 54.6％) in Changzhi ESCC patients showed significant differences with Linzhou ESCC patients (all P ＜0.05).The genotypic frequencies of TT (4.1％ vs 15.0％),CT (41.2％ vs 52.0％) and CC(54.6％ vs 33.0％) showed significant differences between Linzhou ESCC patients and the healthy immigrator controls (all P ＜ 0.05),and the frequencies of TT (4.1％ vs 14.1％) and CC (54.6％ vs 34.8％) showed significant differences between Linzhou ESCC patients and Changzhi healthy controls (all P ＜ 0.01).Meanwhile,there were significant differences between ESCC patients (including Changzhi and Linzhou ESCC patients) and healthy controls (including the healthy Changzhi,Linzhou and immigrator controls) in genotypic frequencies of CT(39.2％ vs 48.7％) and CC (48.8％ vs 38.2％) (all P ＜ 0.01).CT and CT + TT genotype could decrease the risk of ESCC compared with the CC genotype (OR =0.630,95％ CI0.481-0.826 ; OR =0.654,95％ CI 0.507-0.844).Conclusion There is a closed relationship between SNP rs3746804 in C20orf54 and susceptibility to ESCC.

Objective:To explore the influence of mind map based nursing mode on psychological status and prognosis of patients undergoing thoracoscopic and laparoscopic esophagectomy.Methods:A total of 116 patients who underwent thoracoscopic laparoscopic esophageal cancer resection in Sanya People′s Hospital, Hainan Province from November 2017 to October 2019 were selected. According to the admission time, all patients were divided into control group and observation group, with 58 cases in each group. The patients in the control group used conventional nursing strategies, and the observation group used the method of relying on mind mapping on the basis of conventional strategies to assist nursing intervention. The negative emotions and coping styles of the two groups at admission and discharge, as well as the ICU re-occupancy rate, unplanned extubation rate, and satisfaction with nursing intervention between the two groups were compared.Results:At admission, there was no significant difference in Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale(SDS) scores between the two groups ( P>0.05). At discharge, the SAS and SDS scores of the observation group were 38.99±5.07 and 37.25±5.59, 43.25±6.49 and 41.26±4.54. The differences between the two groups were statistically significant ( t values were 3.939, 4.241, all P<0.01). At admission, there was no statistically significant difference in the scores of facing, yielding, and avoiding between the two groups ( P>0.05). At discharge, the scores of face, yield, and avoidance of the observation group were 15.47±1.86, 8.92±1.16, 9.05±1.18, and the control group were 13.32±1.60, 11.11±1.56, 12.03±1.56, the differences between the two groups were statistically significant ( t values were -6.674, 8.579, 11.603, all P<0.01). The ICU re-occupancy rate and unplanned extubation rate were 1.72% (1/58) and 3.45% (2/58) in the observation group, and 13.79% (8/58) and 15.52% (9/58) in the control group, the differences were statistically significant ( χ2 values were 4.336, 4.921, all P<0.05). The observation group ′s satisfaction with nursing intervention, communication ability, professional knowledge, and disease mastery scores were 6.81±1.95, 7.02±2.01, 8.12±1.23, and the control group were 5.35±2.11, 5.71±1.87, 6.21±0.99, the differences were statistically significant ( t values were -3.870, -3.634, -9.213, all P<0.001). Conclusions:For patients undergoing thoracic laparoscopic esophageal cancer resection, the use of mind-mapping-based nursing intervention is beneficial to improve the patient ′s psychological condition, prognosis and nursing satisfaction.

Objective:To investigate the characteristics of natural killer (NK) cell subsets and function in methicillin-resistant staphylococcus aureus (MRSA) sepsis, and to assess the influence of matrix metalloproteinase (MMP) to NK cell function in MRSA sepsis patients.Methods:Twenty-one MRSA sepsis patients who were hospitalized in our department between January 2017 and June 2018 were enrolled. Eleven healthy individuals were served as healthy controls. Peripheral blood mononuclear cells (PBMCs) were isolated. NK cell subsets were investigated by flow cytometry. NK cell function was assessed by measuring CD107a, CD69, and CD16 expression in co-culture system between PBMCs and different target cells. MMP mRNA was semi-quantified by real-time PCR in purified NK cells. The influence of NK cell function was assessed by measuring CD107a expression in co-culture system between NK cells with MMP inhibitor stimulation and target cells.Results:There was no significant difference of total NK cell percentage between healthy controls and MRSA sepsis patients ( P>0.05). CD56brightCD16 -NK [(5.36±1.02)% vs (4.30±0.89)%] and CD56 -CD16 +NK [(24.04±2.92)% vs (9.70±1.54)%] percentage was elevated ( P<0.05), while CD56dimCD16 +NK percentage [(71.22±13.03)% vs (87.64±7.05)%, P<0.01] was reduced in MRSA sepsis. NK cells recognized and killed target cells via different receptors upon activation. CD107a [(33.55±3.84)% vs (25.34±6.20)%] and CD69 percentage [(14.96±1.47)% vs(18.80±1.49)%] was decreased ( P<0.0001), while CD16 MFI was increased [(247.1±50.31) vs (189.4±57.54), P<0.01] in MRSA sepsis patients in comparison with healthy controls. MMP-1/2/3/9 mRNA relative levels were elevated in purified NK cells from MRSA sepsis patients ( P<0.01). Inhibition of MMP in NK cells from MRSA sepsis patients promoted CD107a percentage [(33.67±8.03)% vs (25.87±6.23)%, P=0.018]. Conclusions:NK cell subsets imbalance and exhaustion is existed in MRSA sepsis, which might be due to the MMP-induced down-regulation of antibody-dependent cell-mediated cytotoxicity.
