Objective To observe the interfering effect of different doses of penehyclidine hydrochloride (PHC) on the mRNA expressions of nuclear factor kappa B (NF-κB) and inducible nitric oxide synthase (iNOS) in the lung tissue of rats with traumatic shock so as to investigate the protective role of PHC in secondary long injury following traumatic shock and the underlying mechanism.Methods The traumatic shock model was established.A total of 104 Wistar rats were randomly divided into four groups:control group,shock group,low dose PHC group ( P1 group) and high dose PHC group ( P2 group).At the beginning of resuscitation,the rats in P1 and P2 groups were given transjugular intravenous injection of 2 ml/kg isotonic saline containing 0.15 mg/kg and 0- 45 mg/kg PHC respectively,while the rats in shock and control groups were injected only isometric isotonic saline.The rats in the four groups were killed at 2 h,6 h,12 h and 24 h after resuscitation respectively to detect the mRNA expressions of NF-κB and iNOS by using RT-PCR and determine the lung wet/dry weight (W/D) ratio,lung permeability index (LPI) and lung injury score (LIS).Results The mRNA expressions of NF-κB and iNOS,lung W/D ratio,LPI and LIS at all the time intervals in the shock,P1 and P2 groups were all significantly increased as compared with those in the control group (P＜0.05).Howerver,the P2 group showed significant reduction in aspects of the mRNA expressions of NF- κB and iNOS,lung W/D ratio,LPI and LIS at all time points and P1 group also had significant decrease regarding the mRNA expressions of NF-κB and iNOS,lung W/D ratio at2 h,6 h,and LPI and LIS at 2 h,6 h,12 h,as compared with the shock group.Meanwhile,P2 group showed evident decrease at 6 h concerning the mRNA expressions of NF-κB and iNOS,lung W/D ratio,LPI and LIS as compared with P1 group (P ＜ 0.05 ).Conclusions PHC,especially at a large dosage,can significantly mitigate the long injury secondary to traumatic shock,and the mechanism may be associated with the inhibition of mRNA expressions of NF-κB and iNOS.

Objective:To analyze the endoscopic characteristics of early gastric cancer and precancerous lesions after Helicobacter pylori ( H. pylori) eradication. Methods:From May 2019 to June 2022, at Shanghai Sixth People′s Hospital affiliated to Shanghai Jiaotong University School of Medicine, the medical data of patients diagnosed with differentiated early gastric cancer and precancerous lesions were collected. A total of 93 patients with early gastric cancer and precancerous lesions who had previous history of H. pylori infection and had undergone standardized eradication treatment were selected, and their endoscopic characteristics were retrospectively analyzed. Independent sample t-test, chi-square test, and Fisher′s exact test were used for statistical analysis. Results:Among 93 patients with early gastric cancer and precancerous lesions after H. pylori eradication, there were 56 males and 37 females, with an average age of (66.9±8.2) years old. The time after H. pylori eradication was 3.4 years (range 1.0 to 7.0 years). A total of 109 early gastric cancer and precancerous lesions were found, including 79 patients with single lesion and 14 patients with multiple lesions (30 lesions). There were 60 cases with 73 lesions in the early gastric cancer group and 33 cases with 36 lesions in the precancerous group. Among 93 patients, 89 cases (95.7%) were diagnosed with atrophy level above C-2 according to Kimura-Takemoto classification under endoscopy. The long diameter of 109 lesions was (1.38±0.70) cm and the short diameter was (1.04±0.53) cm. A total of 80 lesions (73.4%) were located in the lower 1/3 part of the stomach, and 53 lesions (48.6%) were located in the lesser curvature. A total of 106 lesions (97.2%) were superficial type (0-Ⅱ) under the endoscopy. The long diameter and short diameter in the early gastric cancer group after H. pylori eradication were both greater than those in the precancerous lesion group ((1.54±0.78) cm vs. (1.06±0.35) cm, (1.16±0.58) cm vs. (0.78±0.33) cm), and the differences were statistically significant ( t=3.53 and 3.73, both P<0.001). There was statistically significant difference in the morphological types between early gastric cancer group after H. pylori eradication and precancerous lesion group ( χ2=11.01, P=0.012). The main morphological type of early gastric cancer after H. pylori eradication was superficial depression type (0-Ⅱc), accounting for 45.2% (33/73), while the precancerous lesions were mainly superficial protruded and flat type, both accounting for 38.9% (14/36). Conclusions:After H. pylori eradication, the endoscopic atrophy range of early gastric cancer and precancerous lesions is mostly above C-2. And the lesions are mostly located in the middle and lower 1/3 part of the stomach, long diameter of lesions <20 mm. The main morphological type is superficial type, especially superficial depression type.

OBJECTIVETo analyze the clinical features of patients with gallbladder cancer from 17 hospitals in 5 Northwestern provinces (autonomous region) of China from 2009 to 2013.

METHODSA total of 2 379 cases with gallbladder cancer in 17 tertiary hospitals from 5 Northwestern provinces of China from January 2009 to December 2013 were reviewed retrospectively. The clinical data was collected by standardized "Questionnaire for Clinical Survey of Gallbladder Cancer in Northwestern Area of China". χ² test was used to analyze the data.

RESULTS(1) Gallbladder cancer from 17 hospitals accounted for 1.6%-6.8% of all bile tract diseases from 2009 to 2013 in Northwestern China, average was 2.7%. Gallbladder cancer accounted for 0.4%-0.9% of abdominal surgery, average was 0.7%. (2) The incidence of gallbladder cancer was higher in the aged females, the ration of female to male was 1.0 to 2.1. The average age of gallbladder cancer was (64 ± 11) years. The occupation of patients was mainly farmers (χ² = 147.10, P < 0.01). (3) 57.2% of the gallbladder cancers were associated with gallstones. (4) The main pathological patterns of gallbladder cancer were moderate and poor differentiated adenocarcinoma, showing an aggressive malignancy. TNM stage IV accounted for 55.1% of all cases, which was associated with the poor prognosis. (5) The curative resection rate was 30.4%.

CONCLUSIONSGallbladder cancer is common in the aged females and mainly at advanced stage. The screening and follow-up of high-risk groups with ultrasound and other methods regularly could increase the early diagnosis rate of gallbladder cancer, aggressive surgical resection combined with other comprehensive treatment could improve the prognosis of patients.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
