Correlation between irritable bowel syndrome as well as its subtype and gallbladder stones / 解放军医学杂志

Objective To analyze the correlation between irritable bowel syndrome(IBS)as well as its subtypes and gallbladder stone.Methods Collected the clinical data of 556 patients who were treated in Department of Gastroenterology of the Sixth Medical Center of Chinese PLA General Hospital from January 2019 to March 2023.The patients were divided into IBS group(n=161)and non-IBS group(n=395).The subjects were investigated by questionnaire,physical examination and blood examination,and the data of gender,age,height,weight,blood pressure and blood biochemical indexes were obtained and compared between two groups.The relation between gallbladder stone and IBS were evaluated by logistic regression analysis.Results There were 90 cases of gallbladder stone in the total population,accounting for 16.2%,including 37 cases of gallbladder stone in IBS group(23.0%)and 53 cases in non-IBS group(13.4%).The prevalence rate of gallbladder stone in IBS group was significantly higher than that in non-IBS group(P<0.05).There were 6 cases of gallbladder muddy stones(3.7%)in IBS group and 3 cases(0.8%)in non-IBS group.And the prevalence rate of gallbladder muddy stones in IBS group was also significantly higher than that in non-IBS group(P<0.05).Logistic regression analysis showed that the age,BMI,total bile acids(TBA),total cholesterol(TC)and combined IBS were independently related to the occurrence of gallbladder stone(P<0.05).In the 161 IBS patients,there were 114 cases of diarrhea-predominant IBS(IBS-D group),including 26 cases(22.8%)of gallbladder stone in IBS-diarrhea(IBS-D,n=114)group and 47 cases of constipation-predominant IBS(IBS-C group),including 11 cases(23.4%)of gallbladder stone.And there were 53 cases(13.4%)of gallbladder stone in the non-IBS group(n=395).Further analysis showed that the prevalence rate of gallbladder stone in IBS-D group was significantly higher than that in non-IBS group(P<0.05).There was no significant difference in gallbladder stone prevalence rate between IBS-C group and non-IBS group(P>0.05).Conclusions There is a correlation between IBS and gallbladder stones.In addition,among the two subtypes of IBS,IBS-D patients may have an increased risk of gallbladder stone compared with non-IBS patients.

Offshore training in navy personnel is associated with uninvestigated dyspepsia / 华中科技大学学报（医学）（英德文版）

To investigate the known and new factors associated with uninvestigated dyspepsia (UD), we surveyed 8600 Chinese navy personnel with offshore training shorter than 1 month or longer than 9 months per year. All respondents were required to complete a questionnaire covering demographics, the Chinese version of the Rome III survey, eating habits, life styles, and medical and family history. The response rate was 94.3% (8106/8600) with 4899 respondents qualified for analysis, including 1046 with offshore training and 3853 with onshore training. The prevalence of UD was higher in the offshore group than in the onshore group (12.6% vs. 6.9%, P<0.001), with a general prevalence of 8.1%. The subjects with offshore training were more likely to suffer from UD and postprandial distress syndrome (OR=1.955, 95% CI 1.568-2.439, P<0.001 and OR=1.789, 95% CI 1.403-2.303, P<0.001, respectively). The multivariate logistic regression analysis showed UD was associated with offshore training (OR=1.580, 95% CI 1.179-2.118, P=0.002), family history (OR=1.765, 95% CI 1.186-2.626, P=0.005) and smoking (OR=1.270, 95% CI 1.084-1.488, P=0.003), but not with alcohol drinking. The association between dysentery history and UD was undetermined/borderline (P=0.056-0.069). In conclusion, we identified offshore training as a new factor associated with UD, and also confirmed 2 known associated factors, family history and smoking.

Changes of palisade ending of extraocular muscle in patients with congenital nystagmus / 中华实验眼科杂志

Background The afferent signals of proprioceptor in extraocular muscles play an important role in controlling eye position and conjugate movement. Palisade ending in the extraocular muscles is the main source of proprioceptive information, and its abnormalities in structure and function may be associated with the occurrence of nystagmus. Objective This study was to observe the changes of palisade ending in the extraocular muscles of patients with congenital nystagmus ( CN) and discuss the probable mechanism. Methods Modified Kestenbaum procedure was performed on 10 patients with CN, and the extraocular muscle samples were collected during the operation. Normal extraocular muscle samples were obtained from the enucleated eyeballs after ocular wound. The ultrathin sections of extraocular muscles were prepared and double-staining by uranyl acetate and lead citrate. The morphological changes of the palisade ending of extraocular muscles were examined under the transmission electron microscopy. Written informed consent was obtained from each subject before surgery. Results The ultrastructure of palisade ending in the extraocular muscle of CN subjects showed the different degrees of alterations. The mild changes included the collapse and disconnection of external capsules and the nonhomogeneous electron-dense substracts. The degeneration and dissociation of myelin in nerve endings, swelling and vacuolation of mitochondria were also exhibited. Myeloid body was found in axon. In the severe patients,the necrosis of Schwann' s cells,dissolve of axon and disappear of capsules were seen. Conclusion The palisade ending of extraocular muscle in the patients with CN are obviously abnormal in comparison with normal one. These alterations are probably associated with the etiology and pathogenesis of CN.

The G990T mutation of the FRMD7 gene in a Chinese family with congenital idiopathic nystagmus / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the mutation of FRMD7 gene in a Chinese family with congenital idiopathic nystagmus.</p><p><b>METHODS</b>Forty-six individuals in the Chinese family with congenital idiopathic nystagmus, including 16 patients, 19 normal siblings and 11 spouses, were investigated under informed consent. Genomic DNA of all 46 members was isolated by standard protocol. The X-linked inherited pattern was ascertained by investigating the history of the family members and the clinical feature of each individual. The genome scan on X chromosome was performed after PCR amplification for microsatellite markers. LOD scores were calculated with Linkage 5.1. Direct DNA sequence analysis was carried out to find the gene mutation responsible for the disease.</p><p><b>RESULTS</b>A maximum LOD score of 8.55 (theta=0) was obtained with polymorphic marker DXS1047. Haplotype construction of the family defined the disease interval between DXS8059 and DXS8033. Direct DNA sequence analysis revealed a heterozygous mutation of G990T in exon 9 of the FRMD7 gene in all patients, which was not present in unaffected family members.</p><p><b>CONCLUSION</b>Congenital nystagmus is a clinically and genetically heterogeneous ocular movement disease. The mutation of G990T of the FRMD7 gene is the underlying molecular pathogenesis for this family with congenital nystagmus.</p>
