Objective To investigate the incidence of insomnia in patients with nasopharyngeal carcinoma during radiotherapy and analyze the influencing factors.Method A sleep quality questionnaire for patients with nasopharyngeal carcinoma during radiotherapy was designed and used for the investigation of the incidence of insomnia as well as the influencing factors related to insomnia.Results The incidence of insomnia was 42.2%.Univariate analysis revealed that radioactive xerostomia,nausea,hospital environmental noise,radioactive oral mucositis,worry about job,worry about prognosis,burp,vomiting,worry about family influence were related to insomnia in nasopharyngeal carcinoma patients during radiotherapy;multivariate analysis showed that radioactive oral mucositis,environmental noise and job stress were the independent factors leading to insomnia(All P<0.05).Conclusions There is a high incidence of insomnia in patients with nasopharyngeal carcinoma during radiotherapy.Radioactive oral mucositis,environmental noise and job stress might be the independent factors relative with insomnia during radiotherapy.

Objective This study aims to investigate the effects of high-fat diet rich in perilla oil on the expression of key genes that regulate hepatic VLDL synthesis in obese rats .Methods Sixty healthy male 5-week old SD rats were randomly divided into 2 groups.The rats in the normal control group (NC, n=12) were given normal diet, and the rats in the high fat group ( HF, n=48) were given a pure high fat diet in order to induce rat models of obesity .In the intervention period, the obesity model rats were randomly divided into 4 subgroups including consistent high fat group (CHF) and three intervention groups depending on perilla oil substitution rate of lard in CHF:20%PO, 50%PO and 100%PO.The serum triglyceride (TG) of the rats was measured after 4 weeks.Real-time PCR was applied to measure microsomal triglyceride transfer protein ( Mtp) and apolipoprotein B ( Apob) mRNA, and western blot assay was used for detecting the expression of MTP and APOB in the liver .Results Compared with the NC group , the CHF rats exhibited significantly high fat deposi-tion.The serum TG was markedly higher and the MTP and APOB were decreased at gene and protein levels in the CHF group compared with the NC group .After the intervention , PO remarkably reduced the level of serum TG and decreased he-patic fat deposition as it showed by pathological examination .At the gene and protein levels , MTP and APOB were upregu-lated by PO to different degrees .Conclusions All the three PO intervention can promote VLDL synthesis and secretion , and decrease the hepatic fat deposition in the obese rats .Furthermore , PO upregulates the expression of MTP at gene and protein levels in a dose-dependent manner .

The lacquer figure with meridian-points marked of the western Han dynasty, unearthed in Tianhui town, Jinniu district, Chengdu in 2012, has been the earliest and the most complete human figure of meridian-acupoints in China so far. There were over ten courses of meridians, and over 100 visible acupoints as well as multiple intaglio inscriptions. All of them are valuable in academic study. The writers introduced the lacquer figure un- earthed in Laoguanshan in terms of the briefs and characteristics of meridian and acupoint distributions, which give the references to the future studies.

Objective This study aims to investigate the effects of high-fat diet rich in perilla oil on the insulin sensitivity-related gene expression in skeletal muscle in insulin resistant rats.Methods The insulin resistant ( IR) rat models were randomly divided into 2 groups, including high fat group ( HF) and perilla oil ( PO) intervention group fed with 20%substitution of lard energy in the HF.The insulin sensitivity of rats was measured after 4 weeks.Theα-linolenic acid ( ALA) content of PO in the rat plasma were analyzed by gas chromatograph.Real-time PCR was applied to measure glucose transporter 4 ( GLUT4 ) and insulin receptor substrate-1 ( IRS-1 ) mRNA, and Western blot assay was used for detecting the expression of GLUT4 and IRS-1 in the skeletal muscle.Results At the gene and protein levels, PO remarkably reduced the level of IRS-1 and upregulated the level of GLUT4 with increasing intake of ALA and serum ALA content in IR rats.The results of hyperinsulinemic-euglycemic clamp test showed no significant difference between the two groups.Conclusions The results of our study suggest that consumption of n-3 PUFA at levels that can typically be found in the diet fed to IR rats in the form of ALA (0.556 g/d) may not improve insulin sensitivity, even though regulating the expression of GLUT4 and IRS-1 in the skeletal muscle.

Objective To measure the endogenous metabolites in synovial tissues of rheumatoid arthritis (RA) rabbits with cold syndrome;To investigate the specificity mechanisms of heat-reinforcing needling for RA. Methods A total of forty healthy purple blue rabbits were randomly allocated to normal group, model group, reinforcing-reducing needling group (RRN), twirling-reinforcing needling group (TRN) and heat-reinforcing needling group (HRN) 8 rabbits in each group. Arthritis rabbits cold model was made with ovalbumin and freezing. Except for normal groupand model group, RRN was given acupuncture of reinforcing-reducing needling at Zusanli (ST36), TRN was given acupuncture of twirling-reinforcing needling at Zusanli (ST36), HRN was administrated acupuncture of heat-reinforcing needling at Zusanli (ST36), once a day and retaining 30 min, a total of seven days. Fresh synovial tissues of rabbits knee joints were extracted after the intervention, then GC-Q/TOF-MS technology were employed to evaluate metabolic profiles. Results The synovial tissues metabolites of TCA cycle, carbohydrate and fatty acid metabolism in model group mainly increased compared with normal group (P<0.05); The synovial tissues metabolites of various kinds above-mentioned decreased compared with model group in all intervention of acupuncture group (P<0.05), and the metabolites of TCA cycle and carbohydrate metabolism in HRN were obviously less than that of RRN and TRN (P<0.05). Conclusion The specificity of heat-reinforcing needling for RA manifests in regulation of TCA cycle and carbohydrate metabolism.

Objective To evaluate the effect of chidamide combined with matrine on proliferation and apoptosis of cutaneous T-cell lymphoma (CTCL) cell lines HH and Hut78,and to explore their apoptotic mechanisms.Methods Both HH and Hut78 cells were treated with 0.4 μmol/L chidamide and 0.6 g/L matrine alone or in combination for 24,48 and 72 hours,with those treated with dimethyl sulfoxide (DMSO) serving as control groups.MTS assay was performed to deteet cellular proliferation rates of HH and Hut78 cells at each time point.After 48-hour treatment,flow cytometry was conducted to detect cell apoptosis,and Western blot analysis to determine expression of apoptosis-related proteins in these cells.Statistical analysis was carried out by using repeated measures analysis of variance,one-way analysis of variance,and least significant difference (LSD)-t test for multiple comparisons.Results Compared with DMSO,chidamide and matrine alone or in combination could inhibit the proliferation of HH and Hut78cells to different extents (F =15.88,558.26,P ＜ 0.05,＜ 0.001,respectively).At 48 hours,the apoptosis rate in Hut78 cells was significantly higher in the matrine group (20.98％ ± 1.53％),chidamide group (22.44％ ± 7.74％) and combination group (44.53％ ± 1.85％) than in the control group (8.42％ ± 4.23％;LSD-t =4.76,5.31,13.69 respectively,all P ＜ 0.05),as well as in the combination group than in the matrine group and chidamide group (LSD-t =8.93,8.37 respectively,both P ＜ 0.01);no significant differences were observed in the apoptosis rate of HH cells between the matrine group (13.98％ ± 3.86％)or chidamide group (13.61％ ± 1.62％) and control group (11.44％ ± 1.43％,both P ＞ 0.05),while the combination group (20.94％ ± 0.64％) showed a significantly higher apoptosis rate compared with the control group,matrine group and chidamide group (LSD-t =7.37,5.40,5.69 respectively,all P ＜ 0.05).In the case of HH cells,the combination group showed significantly higher cleaved caspase-3 expression (all P ＜ 0.05),but significantly lower protein expression of E-cadherin,nuclear factor (NF)-κB,phosphorylated-Bad (p-Bad) and Bcl-2 compared with the other 3 groups (all P ＜ 0.05).In the case of Hut78 cells,the expression of E-cadherin,NF-κB,p-Bad and Bcl-2 was significantly lower in the matrine group,chidamide group and combination group than in the control group (all P ＜ 0.05),while cleaved caspase-3 expression was significantly higher in the chidamide group and combination group than in the control group (both P ＜0.05).No matter in HH cells or in Hut78 cells,there were no significant differences in Bad protein expression between the 4 groups (all P ＞ 0.05).Conclusion Chidamide in combination with matrine can inhibit proliferation and induce apoptosis of HH and Hut78 cells,likely by regulating the expression of apoptosis-related proteins E-cadherin,NF-κB,p-Bad,Bcl-2 and cleaved caspase-3.

Objective:To explore the threshold of tidal breathing nasal nitric oxide (TB-nNO) in diagnosing primary ciliary dyskinesia (PCD) in children aged 3 to 5 years.Methods:Retrospective study.The TB-nNO values were examined of 165 healthy children aged 3-5 in a kindergarten in Xicheng District, Beijing, from March 27 to March 29, 2018, which were also measured in children aged 3-5 years who were diagnosed as PCD, cystic fibrosis, bronchiolitis obliterans, bronchiectasis caused by other diseases and asthma in the Second Department of Pediatric Pneumology, Beijing Children′s Hospital, Capital Medical University from January 2018 to December 2021.Relevant factors associated with TB-nNO in normal children were screened by a multiple linear regression model.The cut-off value of TB-nNO in diagnosing PCD in preschool children aged 3-5 years was determined by calculating the maximum area under the receiver operating characteristic (ROC) curve.Results:TB-nNO value in healthy children aged 3, 4 and 5 years were (94.8±36.4) nL/min, (103.3±50.7) nL/min and (106.9±61.5) nL/min, respectively.The mean TB-nNO value in 9 children with PCD was (18.9±10.8) nL/min.TB-nNO values in 49 children with asthma, 19 children with bronchiolitis obliterans, 17 children with bronchiectasis and 6 children with cystic fibrosis were (97.7±51.1) nL/min, (93.2±49.2) nL/min, (93.7±75.3) nL/min and (45.4±18.2) nL/min, respectively.Using 30 nL/min of TB-nNO as the cut-off point, the sensitivity and specificity of TB-nNO in diagnosing PCD were 88.9% (8/9) and 96.9%, respectively.The area under the ROC curve was 98.3% (95% CI: 95.3%-100.0%). Conclusions:TB-nNO value of 30 nL/min can be used as the cut-off point in the diagnosis screening of PCD in children aged 3-5 years.Its diagnostic value in this age group should be further evaluated.

OBJECTIVEThe distal external iliac lymph nodes are located along the external iliac artery between the deep circumflex iliac vein and the inguinal canal. Our study aimed to investigate the incidence of metastasis in distal external iliac lymph nodes and its association with clinicopathological factors in patients with early stage cervical cancer, and to determine the role of distal external iliac lymph nodes dissection in the surgery.

METHODSFive hundred and twenty-four patients with early stage cervical cancer underwent radical hysterectomy and bilateral pelvic lymphadenectomy in the Shandong Province Cancer Hospital between June 1995 and December 2011, and their clinicopathological features were analyzed retrospectively.

RESULTSOf the 524 patients, 124 (23.7%) had pelvic lymph node metastasis. The metastasis rates were 16.2% (85 of 524 patients) in the obturator lymph nodes, 12.2% (64 of 524 patients) in the internal and external iliac lymph nodes, 2.9% (15 of 524 patients) in the common iliac lymph nodes, 2.1% (11 of 524 patients) in the distal external iliac lymph nodes, and 1.7% (9 of 524 patients) in the para-aortic nodes. The incidence of isolated positive distal external iliac lymph nodes was 0.2%. Univariate analysis showed that lymphovascular space invasion, pelvic lymph node metastases (excluding distal external iliac lymph nodes) were significantly associated with distal external iliac lymph node metastasis (P < 0.05). Logistic regression analysis showed that pelvic lymph node metastasis (excluding distal external iliac lymph nodes) was the independent risk factor for metastasis to distal external iliac lymph nodes.

CONCLUSIONSIn early stage cervical cancer, distal external iliac lymph node metastasis is rare, especially in cases with stage IA or without pelvic lymph node metastasis. Less extensive pelvic lymphadenectomy may be considered in these patients in order to reduce operative complications and improve patients' quality of life. The deep circumflex iliac vein may be an appropriate landmark for the caudal limit of external iliac lymphadenectomy. However, if pelvic lymph node metastasis (excluding distal external iliac lymph nodes) is found by intraoperative rapid pathological diagnosis, systematic pelvic lymphadenectomy including removal of the distal external iliac lymph nodes should be performed in order to reduce the risk of distant metastasis.

Objective:To investigate the relationship between peritoneal thickness and baseline solute transport function in peritoneal dialysis (PD) patients, and analyze the factors affecting the function of peritoneal transport.Methods:Non-diabetic end-stage renal disease (ESRD) patients admitted to the Second Hospital of Longyan City from January 2017 to June 2019 were enrolled in this study. The thickness of the peritoneal membrane was measured by color ultrasound instrument before the peritoneal catheterization. Standard peritoneal equilibration test (PET) was performed after one month of peritoneal dialysis. The ratio of corrected creatine in 4 h dialysate to 2 h serum creatine (D/Pcr) was used as a solute baseline transport index, and according to the D/Pcr evaluation results, the patients were divided into high/high average transfer (H) group (D/Pcr≥0.65) and low/low average transfer (L) group (D/Pcr<0.65). The clinical data, peritoneal thickness and peritoneal dialysis related indicators between the two groups of patients were compared. Binary logistic regression was used to analyze the factors affecting the function of peritoneal transport.Results:The amount of peritoneal ultrafiltration in H group was significantly lower than that in L group, intraperitoneal creatinine clearance (Ccr) and peritoneal thickness were significantly higher than those in L group (both P<0.05). Pearson and Spearman correlation results showed that the thickness of peritoneal membrane positively correlated with D/Pcr ( r=0.673, P<0.05), peritoneal Ccr ( r=0.261, P<0.05), and negatively correlated with ultrafiltration of peritoneal dialysis ( r=-0.365, P<0.05). Partial correlation analysis showed that the peritoneal thickness was positively correlated with the solute transport index D/Pcr ( r=0.539, P<0.05) and the peritoneal Ccr ( r=0.338, P<0.05). Binary logistic regression results showed that peritoneal thickening was a risk factor affecting peritoneal transport function ( OR=1.175, 95% CI 1.009-1.369, P<0.05). Conclusions:There is a positive correlation between the peritoneal membrane thickness and the baseline solute transport index in patients with non-diabetic peritoneal dialysis. Peritoneal thickening is a risk factor affecting peritoneal transport function.

OBJECTIVETo compare the efficacy differences between manual acupuncture (MA) and electroacupuncture (EA) in the treatment of hemiplegia after acute ischemic stroke.

METHODSSixty-eight patients of hemiplegia after acute ischemic stroke were randomized into a MA group (34 cases) and an EA group (34 cases). The routine western medication and bilateral Dingnieqianxiexian (MS 6) were adopted in the two groups. The needles were retained for 30 min. In the MA group, the even-needling technique was used for 3 times during the needle retaining, 1 min each time. In the EA group, on the basis of manual stimulation, EA therapy was added, with disperse-dense wave, 5 Hz/20 Hz. The treatment was given once every day, 6 treatments a week, totally for 2 weeks. US National Institutes of Health stroke scale (NIHSS) score, the simplified Fugl-Meyer motor function (FMA) score and Barthel index (BI) were observed before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSNIHSS score was reduced apparently after treatment in the two groups (both<0.01). The score in the EA group was lower than that in the MA group (<0.05). After treatment, FMA score and BI score were all increased apparently in the two groups (all<0.01) and the scores in the EA group were higher than those in the MA group (both<0.01). The total effective rate was 94.1% (32/34) in the EA group and was 85.3% (29/34) in the MA group. The efficacy in the EA group was better than that in the MA group (<0.05).

CONCLUSIONSEA acts on the rehabilitative effect on nerve defect function in the patients of hemiplegia after acute ischemic stroke. It improves limb motor function and the ability ofdaily life activity. The efficacy is better than that of MA.
