Objective To observe the efficacy of electroacupuncture(EA) on the acupoint combination of He-(sea) points, front-mu points, and shu-points(abbrev. He-Mu-Shu) for the treatment of functional diarrhea, and to explore the effect of He-Mu-Shu point combination EA on the anxiety of patients. Methods A randomized controlled clinical trial was performed in 62 functional diarrhea patients. All of the patients were randomly divided into He-Mu-Shu group(32 cases) and medicine group(30 cases). He-Mu-Shu group was treated with EA on unilateral Quchi, Shangjuxu, Tianshu, Dachangshu point alternatively, and medicine group was treated with oral use of Loperamide hydrochloride capsules. Both groups were treated for 4 continuous weeks. Defecation frequency, stool property and anxiety scores were observed before treatment and 2, 4 weeks after treatment. Results After treatment, weekly defecation frequency, stool property and anxiety scores were improved in both groups, and the differences were statistically significant compared with those before treatment(P < 0.05). He-Mu-Shu point combination EA had better effect on improving weekly defecation frequency, stool property and anxiety scores of functional diarrhea patients than Loperamide hydrochloride capsules, and the differences were statistically significant (P < 0.05). Conclusion The clinical efficacy and anxiety-relief action of He-Mu-Shu point combination EA on functional diarrhea are superior to oral use of Loperamide hydrochloride capsules.

Objective To study the safety,feasibility and efficacy of thoracoscopic hepatectomy for liver carcinoma. Methods Thoracoscopic hepatectomy was performed in 3 cases with single liver neoplasm from 2007 to 2011,including hepatocellular carcinoma ( HCC ) in one case and metastatic liver cancer in 2 cases.By preoperative imaging the tumor was located accurately to simulate the port position in operation.Patients were placed in a left lateral decubitus position,and 3 ports were inserted into the chest wall surrounding the tumor. Through the use of intra-operative thoracoscopic uhrasonography (IOTU),the diaphragm just above the tumor was opened.IOTU was performed on the liver surface and the resection line was marked.Throughout the course of parenchymal transection,IOTU was performed repeatedly to guide the resection line,and ensure the complete removal of the tumor.After meticulous hemostasis of the resection surface,the diaphragm was closed. A thoracic drain was left. Results Thoracoscopic hepatectomy succeeded in all 3 cases,the median total operating time was 150 min (110 -210 min),and the medianblood loss was 297 ml (130 -600 ml). Patients recovered quickly and had no major post-operative complications.During 9 to 42 months' follow-up,one patients died of other cause,no relapse of the diseases was found. Conclusions Thoracoscopic hepatectomy is a safe and feasible operation in selected patients and has advantages in post-operative morbidity and in hospital time.

Objective: To test applicability of the Center for Epidemiological Studies Depression Scale (CES-D) in different age groups in urban China, and to develop age norms. Methods: In this cross-sectional study, the CES-D was administrated to 16047 community participants with average age of (37.7±21.3) years (age ranged 11～100) in 21 provinces, who were as the norming sample. Criterion validity was tested in 349 psychiatric patients with average age of (32.0±12.1) years (age ranged 16～81) in 4 cities. A subsample (199 workers, 100 col-lege students, and 30 teachers in Beijing, Dongguan, and Baotou) was drawn from the national sample to provide 8 week interval test-retest reliability. Results: The Cronbach α was 0.90 for the scale, and 0.68～0.86 for its fac-tors. The 8 week interval test-retest correlation was 0.49 for the scale (P <0.01) and 0.39～0.51 for factors (P<0.01) . The result of confirmatory factor analysis supported the original 4-factor structure (RMSEA=0.057, CFI =0.976, GFI=0.948) . Patients scored higher than community sample [(21.72±13.39 ) vs.(13.24±10.33),P <0.01], and depression patients scored the highest [(27.82±14.42), P<0.01] . Age difference was signifi-cant. Age groups over 60-year-old scored higher than all the other age groups under 60-year-old (P<0.01). Con-clusion: The Chinese version of CES-D shows good refiability and validity across all ages in urban population-

Objective To explore a rapid,simple and effective therapy for serious pneumothorax which could be used in pre-hospital and in-hospital first-aid.Methods Sixty-seven patients were randomly divided into the observation group and control group .Patients in the observation group were treated using laparoscopic trocar for rapidly closed thoracic drainage,and patients in the control group were treated by using the traditional large caliber drainage tube and the intercostal incision method of conventional closed thoracic drainage.The operation time,remaining time of drainage,length of stay,effective rate,and complications,including of postoperative pain,hemorrhage,subcutaneous emphysema and infection were observed in both groups. Results The total effective rate was 94.1%(32/34) in the observation group,which was significantly higher than that in the control group(90.9%,30/33)(x2=1.876,P＞0.05).No significant difference was found on the remaining time of drainage and length of stay between the two groups(remaining time of drainage:[4.56±1.65]d vs.[6.26±3.45]d;length of stay:(6.0±2.6)d vs.(6.7±2.2)d ,t=1.335 and 0.779,respectively,Ps＞0.05).The operation time of using laparoscopic trocar was significantly lower than that of the control group((5.00±1.28)min vs.(15.00±4.03)min,t=3.031,P＜0.05).The incision length was(0.95±0.11)cm in the observational group,which was significantly lower than that in the control group((2.41±0.52)cm ,t=2.585,P＜0.05).Postoperative pain occurred in 14.7%(5/34) of patients in the observational group,which was significantly lower than that in the control group(87.9%(29/33))(t=2.983,P＜0.05).In the observational group no hemorrhage and infection occurred,whereas in the control group the hemorrhage and infection rate was 36%(12/33) and 33%(11/33),respectively(x2=5.880 and 3.687,respectively,Ps＜0.05). Conclusion The use of laparoscopic trocar for rapidly closed thoracic drainage in the treatment of serious pneu-mothorax is simple,easy,convenient,effective and reliable,with few complications.This therapy is suitable for using in pre-hospital and in-hospital first-aid.

To investigate theological properties of common hydrophilic gel excipients such as Carbopol based on viscosity, the viscosity was determined by rotation method and falling-ball method. Linear regression was made between ln(eta) and concentration, the slope of which was used to explore the relation between viscosity and concentration of different excipients. The viscosity flow active energy (E(eta)) was calculated according to Arrhenius equation and was used to investigate the relation between viscosity and temperature of different excipients. The results showed that viscosities measured by two methods were consistent. Concentration of guargum (GG) and hydroxypropylmethyl cellulose (HPMC) solution had a great influence on the viscosity, k > 5; while concentration of polyvinylpyrrolidone-K30 (PVP-K30) and polyethylene glycol 6000 (PEG6000) exerted a less effect on viscosity, k < 0.2; viscosity flow active energy of different excipients were close, which ranged from 30 to 40 kJ x mol(-1). Therefore, theological properties study could provide the basis for application of excipients and establish a foundation for the research of relation between excipients structure, property and function.

Objective:To investigate the expression of acetyl-CoA carboxylase 1 (ACC1) in ovarian cancer tissues and cells, and the related mechanisms of the effect of ACC1 on cell migration and lipogenesis in ovarian cancer.Methods:Samples including 1 case of normal ovarian tissue, 1 case of ovarian cancer primary lesion tissue and 1 case of ovarian cancer omentum metastatic tissue diagnosed by pathology examination of patients undergoing surgery resection who admitted to Linyi Cancer Hospital between January 2019 and December 2021 were collected. Immunohistochemistry was used to detect the protein levels of ACC1 and Yin Yang protein 1 (YY1) of all tissues. The PROMO database was used to predict the possible binding sites of YY1 and ACC1 promoter region. Through the assembled viral vector, the HEY cells of human ovarian cancer with ACC1 or YY1 expression [the untreated cells were treated as the negative control (NC)], or knocked down ACC1 or YY1 (the interference sequence sh1, sh2, sh3 was transferred to the target gene, and the negative control sequence shNC was transferred to the interference sequence). Double luciferase reporter gene assay was used to verify the binding sites of YY1 and ACC1 promoter and the activity of transcriptional regulation. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and Western blot were used to detect the mRNA and protein expression levels of ACC1 and YY1 in the treated HEY cells, respectively. Transwell assay was used to detect the migration ability of HEY cells. Oil red O staining and Nile red staining were used to detect the lipid droplets in HEY cells.Results:The immunohistochemical scores of ACC1 and YY1 were 0, 2, 8 scores and 0, 4, 6 scores, respectively in normal ovarian tissue, primary lesion of ovarian cancer, and omentum metastatic tissue. Transwell assay showed that the number of invasive HEY cells in ACC1 overexpression group was more than that in NC group [(87.7±7.4) vs. (52.2±4.2), t = 5.19, P = 0.003]. The number of invasive HEY cells in ACC1-sh1 group, and ACC1-sh2 group with the knockdown of ACC1 was less than that in shNC group [(21.2±1.5), (29.7±2.3) vs. (56.2±5.3); t value was 6.41, 3.77; P < 0.001, P < 0.005]. The number of lipid droplets in HEY cells in the ACC1 overexpression group was more than that in the control NC group [Oil red O staining: (301±25) vs. (215±21); Nile red staining: (287±15) vs. (207±10); all P < 0.05]; the number of lipid droplets in HEY cells in ACC1-sh1 and ACC1-sh2 group with the knockdown of ACC1 was less than that in ACC1-shNC group [Oil red O staining: (113±8), (119±12) vs. (195±18); Nile red staining: (82±8), (117±11) vs. (165±17); all P < 0.05]. The result of dual luciferase reporter assay showed that overexpression of YY1 promoted the luciferase activity of the wild type ACC1 promoter region report gene ( P = 0.003), while the luciferase activity of the report gene was inhibited compared with the wild type after the mutation of binding sites of YY1 in ACCI promoter region ( P = 0.008). Western blot results showed that the expression levels of YY1 and ACC1 protein in HEY cells with YY1 overexpression group were higher than those in NC group, which indicated a synergistic increasing trend of both YY1 and ACC1; the expression levels of YY1 and ACC1 protein in YY1-sh1 group, YY1-sh2 group and YY1-sh3 group with the knockdown of YY1 were lower than those in the control YY1-shNC group, which indicated a synergistic decreasing trend of both YY1 and ACC1. Conclusions:ACC1 and YY1 are highly expressed in ovarian cancer metastatic tissues and both show a positive correlation trend. The expression level of ACC1 in vitro has an impact on cell migration and lipogenesis in ovarian cancer via YY1 transcriptionally regulating ACC1.
