Objective To analyze the characteristics and applicability of the quality of life (QOL) evaluation scale for patients with idiopathic pulmonary fibrosis (IPF). Methods The IPF-QOL evaluation scales at home and abroad were retrieved and analyzed comprehensively and deeply in terms of fields, number of items, scoring methods, applicability and correlation. Results In the literature area of IPF-QOL evaluation scale, the contents mainly included symptoms,daily activity ability, psychological activity, social activity, economic status, curative effect, etc, and the IPF health-related quality of life, dyspnea, cough and other symptoms were evaluated; the number of related items was between 5-74, and Likert 5 grade scoring method was mostly adopted,with scoring results of 0-100 points; the classical scoring theory such as reliability, validity, responsiveness, feasibility, etc were mainly used to analyze the scale assessment, lacking the application of modern measurement theory; mostly, the studies were concentrated in foreign countries,and relatively few in China, especially lack of the development of the evaluation scale for the combination of disease and symptoms based on Chinese culture. Conclusion The development of IPF-QOL evaluation scale has become a research hotspot, and in clinical application, it is necessary to base on the different characteristics of the scale to improve the accuracy of the evaluation results; in the scale development process, the standardization, comprehensiveness of assessment, and the rationality of scoring results should be strengthened in order to obtain an effective tool which can be provided and suitable for IPF-QOL evaluation.

Objective: To investigate the effect of zinc supplementation on expression of MT-1 and MT-2 mRNA in placenta and small intestine of pregnant rats. Method: Eighteen healthy pregnant SD rats were randomly divided into two groups,normal control (ZC) and zinc supplement group (ZS). Rats in both groups were fed the same normal diet. Rats in ZC group drank deionized water and those in ZS group drank the water supplemented with 1.26 mmol/L Zn. At gestational 9.5d and 17.5d, serum zinc was determined by atomic absorption spectrophotometer and the expression of MT-1 and MT-2 mRNA of placenta and small intestine was examined by RT-PCR. Results: Serum zinc levels at gestational 9.5d and 17.5d were higher in ZS group. Relative expression of both MT-1 and MT-2 mRNA in placenta, MT-1 mRNA at gestational 17.5d and MT-2 mRNA at each time point were higher in ZS group. At gestational 9.5d, there was no difference between two groups in expression of MT-1 mRNA. Conclusion: The expression of MT-1 and MT-2 mRNA in placenta and small intestine was up-regulated by dietary zinc supplementation during pregnancy.

Gallstone ileus is a rare mechanical ileus,which was caused by discharge of giant gall bladder stone to the intestine.Understanding the causes of ileus is the key factor for treatment,and surgical treatment is the treatment of choice.An old patient with gallstone ileus was admitted to the Second Affiliated Hospital of Soochow University in April 2013.Preoperative X ray detection and computed tomography showed gallbladder wall thickening,formation of a sinus tract between the gall bladder and the duodenum,and intestinal ileus in the left iliac region (the diameter of the stone was about 4 cm).The patient received medical treatment for 3 days and then exploratory laparotomy + lithotomy.Gall bladder stones were not detected during the operation,so the gall bladder was preserved.The patient was followed up till December 2013,the sinus tract was disappeared under B sonography,and the cholecystitis was cured.

Objective To compare the immune effects of Coxsackievirus B3 (CVB3) capsid protein VP1 expressed bacterially, recombinant adenovirus rAd/VP1 and recombinant plasmid pcDNA3/VP1which express VP1 protein in mice. Methods After expressed in prokaryotic cells, VP1 protein was purified. Recombinant adenovirus rAd/VP1 and recombinant plasmid pcDNA3/VP1 were amplified and extracted. Six to 8-week-old, male BALB/c mice were divided into four groups randomly. Each group contained 18 mice. The mice of pcDNA3/VP1 group or VP1 protein group were immunized intramuscularly with three injections at three weeks apart, of recombinant plasmid pcDNA3/VP1 at a dose of 100 μg/mouse or recombinant protein VP1 at a dose of 50 μg/mouse. The mice of rAd/VP1 group were immunized intramuscularly twice at two weeks interval with rAd/VP1 at a dose of 1.2 × 107 PFU. The control group was mock-immunized with 100 μl of PBS intramuscularly. Mice were bled from the retroorbital sinus plexus every two weeks after each immunization. ELISA and micro-neutralization test were used to detect levels of CVB3-specific IgG antibody and neutralizing antibody titers in the sera of immunized mice. Three weeks after the last immunization, the cytotoxic T lymphocyte(CTL) killing activity of spleen lymphocytes was detected with CCK-8 assay. Subsequently, virus titers in the sera of immunized mice were determined by the 50% cell culture infective dose( CCID50 ) assay on HeLa cell monolayers and percentage of animals surviving were observed after lethal CVB3 attack over a period of 21 days. Results The titers of specific IgG antibody and neutralizing antibody in sera of VP1 protein immunized mice were higher than other groups( P ＜0.05 ). While CTL killing activity of spleen lymphocytes of VP1 protein immunized mice was lower than mice in rAd/VP1 group( P ＜0. 05). Virus titers in sera of VP1 protein immunized mice were lower than the mice in pcDNA3/VP1 or rAd/VP1 groups ( P ＜ 0.05 ), while survival rate was significantly higher than these two groups ( P ＜ 0.05 ).Conclusion VP1 protein induced higher level of humoral immune response and acquired obvious immune protection effects in mice. The immunizing potency of VP1 protein vaccine surpassed plasmid pcDNA3/VP1or recombinant adenovirus rAd/VP1. It appeared to be a promising candidate among the three different vaccines.

Objective To investigate the efficacy and safety of compound azintamide on dyspepsia symptoms. Methods One hundred and eighty dyspepsia patients were divided into two groups according to dyspepsia symptom related with gastrointestinal disease ( group A) or biliary system disease (group B),whose dyspepsia symptom were not improved by the Domperidone 10 mg tid for 2 weeks. Two tablets of compound azintamide were administered orally following a meal, tid for 2 weeks. The changes of symptoms score of upper abdominal distention, upper abdominal pain or discomfort anorexia and effective rate as well as adverse events were recorded. Results Compound azintamide greatly improved the symptoms of upper abdominal distention, upper abdominal pain or discomfort and anorexia. All symptoms scores were significantly decreased after 2 weeks of compound azintamide (P < 0.01). The effective rate of each symptom and total symptoms score were more than 84.9% and 92.5%. One patient reported mild rash at the fourteenth days, which disappeared 3 days later. Conclusion Compound azintamide showed effective and safety in treatment of patient with dyspepsia symptoms when Domperidone therapy is not satisfactory.

Objective:To investigate the effect of combined use of midazolam and remifentanil without muscle relaxant on tracheal intubation in female patients undergoing breast surgery.Methods:A retrospective analysis was performed on 40 female patients with breast disease who underwent tracheal intubation and general anesthesia at The First Affiliated Hospital of Zhengzhou University between January 2023 and June 2023. These patients were divided into a control group ( n = 20) and an observation group ( n = 20) based on whether muscle relaxants were applied at the time of intubation. The control group received intravenous rocuronium bromide, whereas the observation group did not use muscle relaxants. Both groups were intravenously administered midazolam (0.1 mg/kg) and remifentanil (4 μg/kg) prior to tracheal intubation. The intubation conditions were evaluated based on factors such as the ease of inserting the laryngoscope and the patient's response to intubation, including coughing. Results:There were no statistically significant differences in age, height, and body mass between the two groups (all P > 0.05). The excellent rate of intubation conditions was significantly lower in the observation group compared with the control group [45% (9/20) vs. 85% (17/20), χ2 = 7.03, P = 0.008). The good rate of intubation conditions was significantly higher in the observation group compared with the control group [40% (8/20) vs. 5% (1/20), χ2 = 7.03, P < 0.05]. There was no statistically significant difference in the excellent and good rates of intubation conditions between the observation and control groups [85% (17/20) vs. 90% (18/20), χ2 = 0.23, P > 0.05]. No significant difference in intraoperative awareness score was observed between the observation and control groups [(2.59 ± 0.44) points vs. (2.61 ± 0.31) points, P > 0.05]. None of the patients in either group exhibited any episodes of arrhythmias. Furthermore, no adverse reactions such as muscle stiffness, nausea, vomiting, or skin itching were observed in either group following the surgical procedure. Conclusion:Without the use of muscle relaxants, intravenous administration of midazolam at 0.1 mg/kg and remifentanil at 4 μg/kg for tracheal intubation in female patients undergoing breast surgery can offer excellent intubation conditions, ensuring that the patient remains unconscious throughout the surgical procedure.

Objective:After the propensity score matching method was used to balance the covariates between groups, the effects of pancreaticoduodenectomy (PD) and total pancreatectomy (TP) on the survival of patients with pancreatic head cancer and related prognostic factors were compared.Methods:The National Cancer Institute Surveillance, Epidemiology and Results (SEER) database were searched and 3 676 patients with pancreatic head cancer from 2010 to 2016 were selected, of whom 3 559 patients underwent PD (PD group) and 117 patients underwent TP (TP group) . Using propensity score matching to balance confounding factors, 117 pairs of cases from PD group and TP group were matched successfully. The Kaplan-Meier curve was used to observe the overall survival rate and cancer-specific survival rate of patients before and after matching. Log-rank test and Cox proportional hazard model were used to analyze and evaluate the impact of different clinicopathological characteristics on the prognosis of patients with pancreatic head cancer.Results:Before matching, the 1, 3, and 5-year cancer-specific survival rates of 3 559 patients in the PD group were 72.8%, 35.1% and 24.9%, and the median survival time was 23.89 months; the 1, 3, and 5-year cancer-specific survival rates of 117 patients in the TP group were 67.9%, 29.4% and 26.1%, and the median survival time was 21.51 months, and all the differences were not statistically significant (all P>0.05). After matching, the 1, 3, and 5-year cancer-specific survival rates of 117 patients in the PD group were 77.8%, 44.5% and 31.8%, and the median survival time was 31.50 months, which was significantly better than that of the TP group, and the differences were statistically significant (all P values <0.05). Cox regression analysis showed that surgical methods, tumor differentiation degree, N staging and pathological types were independent risk factors for overall survival and cancer-specific survival. Conclusions:Surgical methods, tumor differentiation degree, N stage and pathological type were independent risk factors affecting the overall survival rate and cancer-related survival rate. The survival benefit of PD was significantly better than that of TP, and the clinical choice of TP treatment for patients with pancreatic head cancer should be cautious.
