Objective To analyze the clinical characteristics of high energy metabolism in lung cancer patients and its correlation with body composition,nutritional status,and quality of life,and to develop a corresponding risk prediction model.Methods Retrospectively analyzed 132 primary lung cancer patients admitted to the First Hospital of Shanxi Medical University from January 2022 to May 2023,and categorized into high(n=94)and low energy metabolism group(n=38)based on their metabolic status.Differences in clinical data,body composition,Patient Generated Subjective Global Assessment(PG-SGA)scores,and European Organization for Research and treatment of Cancer(EORTC)Quality of Life Questionnaire-Core 30(QLQ-C30)scores were compared between the two groups.Logistic regression was used to identify the risk factors for high energy metabolism in lung cancer patients,and a risk prediction model was established accordingly;the Hosmer-Lemeshow test was used to assess the model fit,and the ROC curve was used to test the predictive efficacy of the model.Results Of the 132 patients with primary lung cancer,94(71.2%)exhibited high energy metabolism.Compared with low energy metabolism group,patients in high-energy metabolism group had a smoking index of 400 or higher,advanced disease staging of stage Ⅲ or Ⅳ,and higher levels of IL-6 level,low adiposity index,low skeletal muscle index,and malnutrition(P<0.05),and lower levels of total protein,albumin,hemoglobin level,and prognostic nutritional index(PNI)(P<0.05).There was no significant difference in age,gender,height,weight,BMI and disease type between the two groups(P>0.05).Logistic regression analysis showed that smoking index≥400,advanced disease stage,IL-6≥3.775 ng/L,and PNI<46.43 were independent risk factors for high energy metabolism in lung cancer patients.The AUC of the ROC curve for the established prediction model of high energy metabolism in lung cancer patients was 0.834(95%CI 0.763-0.904).Conclusion The high energy metabolic risk prediction model of lung cancer patients established in this study has good fit and prediction efficiency.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

To optimize the ethanol extraction technology parameters of Fengyin Decoction by orthogonal experiment combined with beetle antennae search(BAS)-genetic algorithm(GA)-back propagation neural network(BPNN). Based on single factor investigation, the extraction temperature, ethanol volume, extraction time, and ethanol concentration were used as orthogonal experiment factors, and entropy weight method was used to calculate the comprehensive scores of aloe-emodin, glycyrrhizic acid ammonium salt, rhein, emodin, chrysophanol, physcion, cinnamaldehyde, 6-gingerol, extraction ratio and fingerprint similarity. BAS-BPNN model was established, and then, GA was used to predict the optimal extraction process. The results showed that BAS-BPNN was optimized to obtain the optimal ethanol extraction process of Fengyin Decoction as follows: extraction temperature of 87 ℃, adding 9 times of 75 % ethanol, and extracting for 47 minutes, with a comprehensive score of 1.052 9. Meanwhile, the optimal process parameters obtained by orthogonal design were as follows: the extraction temperature of 80 ℃, adding 10 times of 75% ethanol, extracting for 30 minutes, with a comprehensive score of 1.003 7. The comprehensive score of the process obtained from the BAS-BPNN model was slightly better than that from the orthogonal test, indicating that the optimized process from BAS-BPNN model was more ideal, so it was finally determined as the best extraction process for Fengyin Decoction. The process of Fengyin Decoction obtained from BAS-GA-BPNN has high extraction efficiency and good stability, which provides reference for the subsequent development and quality control.

Background: Accumulating documents have demonstrated that long noncoding RNAs (lncRNAs) play critical roles in tumorigenesis. As an lncRNA, nuclear-enriched abundant transcript 1 (NEAT1) has been identified to be involved in the progression of many types of cancers. However, the biological function of NEAT1 in cervical cancer is not fully investigated. The aim of this study was to disclose the specific biological function of lncRNA NEAT1 in cervical cancer progression. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to identify the expression of lncRNA NEAT1 in the cervical cancer tissues and cell lines. All cervical cancer samples used in this study were collected from the Affiliated Suzhou Hospital of Nanjing Medical University between September 2012 and September 2017. The correlation between NEAT1 expression and the overall survival rate of cervical cancer patients was analyzed by Kaplan-Meier analysis. The effects of NEAT1 knockdown or overexpression on cell proliferation were tested by performing MTT assays and colony formation assays. Transwell assays were conducted to detect the migratory ability of cervical cancer cells, in which NEAT1 was silenced or overexpressed. Western blotting was utilized to validate whether NEAT1 promotes cervical cancer progression through activating PI3K-Akt signaling pathway. Results: High expression of NEAT1 predicted poor prognosis of cervical cancer patients (χ = 0.735, P = 0.005). Knockdown of NEAT1 decreased the number of colonies in CaSki cell from 136.667 ± 13.503 to 71.667 ± 7.506 (t = -18.76, P = 0.003) and decreased the number of colonies in HeLa cell from 128.667 ± 13.317 to 65.667 ± 7.024 (t = -5.54, P = 0.031). However, overexpression of NEAT1 increased the number of colonies in SiHa cell from 84.667 ± 12.014 to 150.667 ± 18.037 (t = 7.27, P = 0.018). Knockdown of NEAT1 decreased the migratory number of CaSki cell from 100.333 ± 9.866 to 58.333 ± 5.859 (t = -8.08, P = 0.015) and reduced the migratory number in HeLa cell from 123.667 ± 12.097 to 67.667 ± 7.095 (t = -6.03, P = 0.026). Overexpression of NEAT1 increased the migratory number of SiHa cell from 127.333 ± 16.042 to 231.333 ± 31.786 (t = 4.92, P = 0.039). Conclusion NEAT1 may exert oncogenic function in cervical cancer and serve as a novel therapeutic target for cervical cancer.

OBJECTIVE: To study the effects of alcohol administration on benign prostate hyperplasia(BPH) and the reproductive toxicity during development of benign prostate hyperplasia. METHODS: Seventy adult male Kunming mice were randomly divided into seven groups:control (group CON), negative control (group NC, injected subcutaneously with soybean oil, 25 mg/(kg·d), intragastric administration of distilled water, 7.5 ml/(kg·d)), alcohol for 7 and 21 days (group AL7 and AL21, intragastric administration with wine of 50% alcohol, 7.5 ml/(kg·d)), testosterone propionate for 7 and 21 days (group TP7 and TP21, injected subcutaneously with testosterone propionate, 25 mg/(kg·d)), testosterone propionate+alcohol for 7 days (group TP+AL7, injected subcutaneously with testosterone propionate, 25 mg/(kg·d), and intragastric administration with wine of 50% alcohol, 7.5 ml/(kg·d)),10 mice in each groups. Twenty-four hours after the last administration, mice were sacrificed. The indexes of prostate and testis and the parameters of sperm were determined in mice. The levels of free radicals, antioxidation and histopathological changes in testis and prostate were determined. RESULTS: Compared with the control, TP7d group, AL7 and AL21d groups, the prostate coefficient of TP + AL7d group was increased significantly and the quantity and quality of sperm were decreased significantly (<0.05), the content of MDA in prostate and testis was increased significantly, meanwhile the activities of SOD and GPx were decreased significantly (< 0.05). Compared with TP21d group, the prostate coefficient of TP + AL7d group had no significant difference (>0.05). CONCLUSIONS The typical BPH state could be induced after 7-day treatment of testosterone propionate and alcohol. The testicular and sperm were damaged which enhanced the oxidative stress in reproductive system. The results indicated that alcohol could significantly promote the prostate hyperplasia induced by testosterone propionate in mice.

BACKGROUNDThe frequencies of regulatory T cells (Tregs) increased over the HIV infection but its counts actually decreased. We proposed that the decrease of Treg counts may cause the reduction of inhibitory effect and thereby account for the over-activation of Tregs during HIV infection. However, it remains unknown whether Tregs are also over-activated and thereafter the activation induced death may lead to the decrease of Tregs.

METHODSTregs were defined as CD4(+)CD25(+)CD127(lo/-) T cells. Eighty-one HIV-1 infected patients were enrolled in our study, and twenty-two HIV-1 seronegative donors were recruited as the control. The levels of HLA-DR on Tregs were determined by FACSAria flow cytometer.

RESULTSCompared to HIV-1 seronegative donors, the levels of HLA-DR on CD4(+)CD25(+)CD127(lo/-) Tregs were significantly increased in HIV-1 infected patients, and its increase was positively associated with viral loads (r = 0.3163, P = 0.004) and negatively with CD4 T-cell counts (r = -0.4153, P < 0.0001). In addition, significant associations between HLA-DR expression on CD4(+)CD25(+)CD127(lo/-) Tregs and the percentages of HLA-DR, CD38, Ki67 expressing CD4(+) and CD8(+) T cells were also identified.

CONCLUSIONHLA-DR on Tregs is a good marker for viral replication and disease progression. The over-activation of Tregs might result in the decrease of Tregs.

OBJECTIVETo investigate the mRNA and protein expression of nucleostemin (NS) in human esophageal squamous cell carcinoma.

METHODSThe mRNA and protein expression of NS were detected in 31 mucosal atypical hyperplasia specimens, 62 esophageal squamous cell carcinoma specimens and the matched normal esophageal mucosa samples by RT-PCR and immunohistochemistry method, respectively.

RESULTSThe positive expression rate of NS protein in normal esophageal mucosa, atypical hyperplasia and esophageal squamous cell carcinoma was 17.7% (11/62), 41.9% (13/31) and 69.4% (43/62), respectively. There was a significant difference among the above three groups (chi2 = 33.676, P < 0.01). The expression levels of NS mRNA in esophageal squamous cell carcinoma (0.971 +/- 0.121) was significantly higher than that in the atypical hyperplasia (0.913 +/- 0.085) and also in the normal esophageal mucosa (0.866 +/- 0.103; F = 14.829, P < 0.01). The expression level of both NS protein and mRNA was positively correlated with histological grade, infiltration depth, and lymph node metastasis (P < 0.05), but not with age, gender or pathological type (P > 0.05).

CONCLUSIONOur results indicate that nucleostemin mRNA and protein are over-expressed in human esophageal squamous cell carcinoma, and it may be related with its oncogenesis.

OBJECTIVETo study the correlation of eating raw fish with primary hepatic carcinoma (PHC), and to investigate the synergistic effect of HBV infection, alcohol consumption and eating raw fish on the oncogenesis of PHC.

METHODSA hospital-based case-control study was conducted among 500 PHC patients and 500 non-cancerous patients in order to compare the history of eating raw fish. The synergistic pathogenetic action of eating raw fish, HBV infection and alcohol consumption on carcinogenesis of PHC was analyzed by crossover analysis and multiple logistic regression.

RESULTSThe rates of eating raw fish in the past between the case (54.8%) and the control group (8.4%) were significantly different (P < 0.001). OR value of suffering PHC in the patients who ate raw fish in the past was 13.6 (95% CI: 9.1-19.5) when compared with the non-cancerous patient. HBV infection, alcohol consumption and eating raw fish showed an interactive effect on the development of PHC, with a relative excessive risk of interaction(RERI) of 195.3 and 17.8; attributable proportion of interaction (API) of 0.8630 and 0.5251; and synergy index (S) of 7.5 and 2.8, respectively.

CONCLUSIONA history of eating raw fish may be an important risk factor for suffering primary hepatic carcinoma. HBV infection, alcohol consumption and eating raw fish may have a synergistic effect on the developing of primary hepatic carcinoma.
