[Clinical and endoscopic characteristics of adult celiac disease].

Objective: The study aimed to analyze the clinical and endoscopic characteristics of adult celiac disease (CD) to provide a scientific basis for more effective CD diagnosis and treatment. Methods: In this cross-sectional study, the clinical and endoscopic data of 96 adult CD patients treated in the Department of Gastroenterology of the People's Hospital of Xinjiang Uygur Autonomous Region from March 2016 to December 2021 were retrospectively collected and analyzed. Results: A total of 96 CD patients were diagnosed, including 33 men and 63 women. The average age was 47±14 years (range, 18-81 years). The disease occurred mainly in the age group of 31-60 years. The median course of the disease was 2.0 (0.2-40.0) years. There were 41 (42.7%) classical and 55 (57.3%) non-classical CD patients. All patients with classical CD showed chronic diarrhea, often accompanied by abdominal pain (46.3%, 19/41), abdominal distension (17.1%, 7/41), anemia (65.9%, 27/41), and chronic fatigue (48.8%, 20/41). The main manifestations of non-classical CD were chronic abdominal pain (58.2%, 32/55), abdominal distension (32.7%, 18/55), anemia (40.0%, 22/55), and osteopenia/osteoporosis (38.2%, 21/55). Compared with non-classical CD, anemia developed more frequently in classical CD, and the difference was statistically significant (P = 0.012). The incidence of complications in CD patients was 36.5% (35/96), and the main complications were thyroid disease (19.8%, 19/96), connective tissue disease (6.2%, 6/96), and kidney disease (6.2%, 6/96). There was no significant difference between classical and non-classical CD (P>0.05). The frequency of endoscopic manifestations in CD patients was 84.4% (81/96). Duodenal bulb endoscopy showed nodular changes (72.9%, 70/96), grooved changes (10.4%, 10/96), and focal villous atrophy (9.4%, 9/96). The main manifestations of descending endoscopy were the decrease, flattening, or disappearance of duodenal folds (43.8%, 42/96), scallop-like changes (38.5%, 37/96), and nodular changes (34.4%, 33/96). Conclusions: Adult CD patients are mostly female. CD occurred mainly in the age group of 31-60 years. The clinical manifestations were mainly those of non-classical CD. Some patients often had other autoimmune diseases. Patients with characteristic endoscopic manifestations should be warned about the possibility of developing CD. Clinicians should strengthen the understanding of CD and reduce the related rates of missed diagnosis.

[Application of ROC and PR curves in the evaluation of clinical diagnostic testing].

This study reviewed the concepts and properties of the receiver operating characteristic (ROC) curve and precision recall (PR) curve, and made suggestions on the application of two curves based on the prevalence in combination with the results of simulation data. This study demonstrated that the ROC curve and PR curve had different properties, which could reflect the performance of diagnostic methods from various aspects. These two curves should be selected with a consideration of prevalence and clinical scenarios. When the prevalence was less than 20%, especially less than 5%, the PR curve could be adopted.

[Factors influencing poor prognosis of mechanical thrombectomy in time window of acute ischemic stroke].

Objective: Investigate the causes of poor prognosis of mechanical thrombectomy in the time window of acute ischemic stroke (AIS) with anterior circulation. Methods: A retrospective analysis was made on the data of 78 patients with anterior circulation AIS who underwent mechanical thrombectomy in the time window from January 2017 to December 2017 in the Department of Vascular Neurosurgery of Liaocheng Brain Hospital. The modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 3 months after operation. According to the prognosis,the patients were divided into the group with good prognosis (42 cases, mRS<2 points) and the group with poor prognosis (36 cases, mRS<3 points). Univariate and multivariate Logistic regression analysis was used to analyze the related factors of poor prognosis. Results: (1) Univariate analysis showed that the prognosis of patients with good combination and primary stenosis of diabetes mellitus and atherosclerosis was lower than that of patients with poor prognosis (P<0.05). The collateral circulation compensation rate and vascular recanalization rate of patients with good prognosis were higher than those of patients with poor prognosis (P<0.05). Learning significance (P<0.05). (2) Multivariate analysis showed that diabetes mellitus (P=0.035), collateral circulation compensation (P=0.011) and primary atherosclerotic stenosis (P=0.042) were independent risk factors for poor prognosis. Conclusion: Perfect preoperative evaluation and strict screening of patients, good collateral circulation compensation,individualized treatment for patients with primary atherosclerotic stenosis,and strict control of postoperative hyperglycemia can improve the clinical prognosis of endovascular therapy.

[A comparative study of intrahepatic cholangiocarcinoma and hepatocellular carcinoma with reference to clinical features and prognosis].

Objective: To comparatively study intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC) with reference to clinical features and prognosis in Chinese Han population. Methods: 699 cases of HCC and 170 cases of ICC confirmed by surgical pathological files from 2009 to 2010 were included and followed-up. The differences in demographic characteristics, hepatitis B virus infection, clinical characteristics, biochemical indexes, tumor markers and prognosis of HCC and ICC were analyzed retrospectively by means of paired t-test, analysis of variance, chi-square test and Pearson's correlation coefficient. Results: Among 869 cases of primary liver cancer, HCC and ICC accounted for 80.43% and 19.57%. The old aged (P < 0.001) male incidence of HCC was higher than that of ICC (P < 0.001). The infection rates of hepatitis B virus were 89.84% and 35.88% in HCC and ICC, respectively, and the infection rates of hepatitis B, serum HBsAg postive rate and DNA account in HCC were higher than ICC (P < 0.001). The incidence of liver cirrhosis and hepatic schistosomiasis in HCC was also significantly different from that in ICC (both P < 0.01). Pearson's correlation analysis showed that there was a significant negative correlation between HCC or ICC tumor type and hepatic schistosomiasis (r = -0.018, P < 0.001), and there was a significant positive correlation between HCC and hepatic cirrhosis (r = 0.179, P < 0.001, and r = 0.528, P < 0.001, respectively). However, the proportion of cirrhosis and schistosomiasis in hepatitis B positive ICC cases was not significantly different from that in HCC cases (P > 0.05). Among the biochemical indicators, there were significant differences between HCC and ICC in the abnormal rate of ALT(P < 0.01), AST(P < 0.05), ALP (P < 0.01), GGT (P < 0.01) and TBIL (P < 0.01) while there was no significant difference between ALB and pre-ALB (P > 0.05) in HCC and ICC groups. The content and abnormal rate of alpha-fetoprotein were higher in HCC (P < 0.01), while the content and abnormal rate of carcinoembryonic antigen and carbohydrate antigen 19-9 were higher in ICC (P < 0.01). The 10-year survival rate and median survival time (46.92% and 80.3 months) of HCC were higher than those of ICC (12.57% and 12.4 months) (P < 0.01). Conclusion: In the study population, compared with ICC cases, the old aged male HCC cases are more common and has higher infection rate of hepatitis B virus and cirrhosis, but liver schistosomiasis is less common. The inflammatory damage, secretion and metabolic function of HCC were different from that of ICC cases, while the synthetic reserve function was similar to that of ICC and the prognosis of HCC cases was significantly better. The incidence of cirrhosis and schistosomiasis in ICC cases with positive hepatitis B virus infection was not significantly different from that of HCC cases.

[The progress of research on the immune pathogenesis and biomarkers in optic neuritis related to neuromyelitis optica].

The idiopathic optic neuritis (ION) which is related to neuromyelitis optica (NMO) and neuromyelitis optica spectrum disorders (NMOSD) is called optic neuritis related to neuromyelitis optica (NMO-ON). Because of the high rates of blindness, disability and fatality of NMO, the heterogeneous clinical presentation, severity of neurologic disability following relapses, and variability of therapeutic responses, reliable and sensitive biomarkers for onset, relapse, and progression in NMO are urgently needed. Currently, detecting aquaporin-4 (AQP4) antibodies (AQP4-IgG or NMO-IgG) in serum is employed as the major supporting approach for the diagnosis of seropositive NMO, however, AQP4-IgG seronegativity in 10% to 25% of NMO patients suggests that there are several other factors involved in NMO immunopathogenesis. Collaborative international studies hold great promise for establishing and validating biomarkers of NMO. This article discusses known and potential biomarkers for NMO. The biomarkers of NMO maybe the potential biomarkers of NMO-ON, for ION is the initial presentation and the earliest stage. (Chin J Ophthalmol, 2019, 55:228-233).

Genetic variations in the UTR of genes related to molting in Eriocheir sinensis.

Crab grows by periodic molting, which is controlled by molt-inhibiting hormone (MIH) and ecdysteroids. Untranslated regions (UTRs) play crucial roles in the posttranscriptional regulation of gene expression. In this study, using crab collected from Changjiang (Yangtze), Huanghe (Yellow), Liaohe, and Yalujiang rivers, 33 haplotypes of the 3ꞌ-UTR of ecdysteroid-regulated protein (ERP) gene were identified, of which 14 haplotypes were observed in more than one individual. One hundred and forty clones of haplotype h2 (41.5%) were observed in samples from all the 4 rivers. Three haplotypes were observed to be insertions. For the whole crab sample, we found a positive Tajima's D value and a negative Fu's Fs test (Tajima's D value = 0.98726; Fu's Fs test = -27.382), although the P values were not significant (P > 0.10). The network profile of these 33 haplotypes presented a single core pattern with h2 as the core. In this study, we found that the UTR of ERP gene had a considerably high genetic polymorphism among crab from regions south to north of China. Furthermore, we observed a relatively high genetic divergence among different haplotypes, which would suggest a high diversity of the crab gene pool.

Protective effect of ischemia preconditioning on ischemia-reperfusion injury in rat liver transplantation.

We explored the protective effect of ischemia preconditioning (IP) on ischemia-reperfusion injury in rat liver transplantation. An orthotopic liver transplantation model was utilized in the study. A total of 54 Sprague-Dawley rats were divided into a control group (group A, no liver transplantation), liver transplantation group (group B, heparin Ringer's lactate solution was perfused via the portal vein before donor liver collection), and liver transplantation with IP group (group C, IP was performed for different time periods before donor liver collection). Liver function, B-cell lymphoma 2 expression in hepatic cells, cell apoptosis, and cellular ultrastructure changes were detected after surgery. After surgery, serum alanine aminotransferase activity was significantly higher in group B than in group A, while it was not clearly enhanced in group C and decreased progressively with increasing cycles of IP as bile capacity gradually increased. Compared with group B, group C showed alleviated injury of hepatic cells, increased B-cell lymphoma 2 expression, and a lower apoptosis index. IP had a protective effect on ischemia-reperfusion injury in rat liver transplantation, and the mechanism correlated with increased B-cell lymphoma 2 expression in hepatic cells and inhibition of cell apoptosis.

A C-type lectin fold gene from Japanese scallop Mizuhopecten yessoensis, involved with immunity and metamorphosis.

C-type lectins are a superfamily of Ca(2+)-dependent carbohydrate-recognition proteins that are well known for their participation in pathogen recognition and clearance. In this study, a putative C-type lectin fold (MyCLF) gene was identified from the Japanese scallop Mizuhopecten yessoensis. The full-length of MyCLF was 645 bp, encoding a polypeptide of 167 amino acids. MyCLF carried a signal peptide of 20 amino acid residues, and a single carbohydrate recognition domain, having relatively high amino acid sequence conservation with C-type lectins reported for other bivalves. The expression of MyCLF mRNA transcripts in adult tissues, after bacterial challenge and during different developmental stages was determined using real-time quantitative RT-PCR. MyCLF was mainly distributed in the mantle, gill, and kidney. The expression of MyCLF clearly increased 3 h after Vibrio anguillarum challenge, and dropped to a minimum level after 9 h compared to the control group. During embryonic development, the expression level increased in the gastrulae, trochophore and early D-shaped larvae, decreased in D-shaped larvae, and then increased hundreds of times in metamorphosing larvae. The results suggested that MyCLF was involved in an immune response and it may play important roles during the metamorphosis phase of M. yessoensis.

Chronically recurrent and widespread tinea corporis due to Trichophyton rubrum in an immunocompetent patient.

A 31-year-old immunocompetent male who presented with a 4-year history of extensive erythematous and scaly plaques involving the abdomen, gluteal and inguen regions with concomitant tinea pedis and onychomycosis is described. Diagnosis was based on positive mycological examination and positive histopathologic examination. Species identification was performed by growth on Sabouraud dextrose agar and by sequencing of the internal transcribed spacer regions of the rDNA region. The pathogen identified was Trichophyton rubrum. The same fungal species was cultured from his abdominal, gluteal, foot and toenail. A combination therapy with systemic terbinafine and topically applied terbinafine cream was successful. A 1-year follow-up did not show any recurrence of infection.

Successful Treatment of Refractory Majocchi's Granuloma with Voriconazole and Review of Published Literature.

Majocchi's granuloma (MG) is a rare deep skin dermatophyte infection that can occur either in immunocompetent or in immunocompromised individuals. Oral itraconazole or terbinafine is considered to be the first choice of treatment. We report an immunocompetent man with deep nodular form of MG, the form which is generally found in immunosuppressed individuals. Previous treatment with either oral itraconazole or terbinafine yielded no apparent improvement. After a series of examination, the man was diagnosed as having Trichophyton rubrum-induced MG mixed with bacterial infection as evidenced by growth of Klebsiella pneumoniae in tissue bacterial culture. The patient was treated with a combination of cefoselis and levofloxacin for bacterial clearance followed by voriconazole treatment. After approximately 4 months of voriconazole treatment, the lesions completely resolved. Alternative medicine (voriconazole) can be considered in case of refractory infections during MG treatment.

Identification and expression analysis of cDNA encoding chitinase-like protein (CLP) gene in Japanese scallop Mizuhopecten yessoensis.

Chitinase-like proteins (CLP) are important members of the glycoside hydrolase family 18 (GH18) and are involved in growth control and remodeling processes. In this study, a CLP transcript was isolated and sequenced from the Japanese scallop (Mizuhopecten yessoensis) after screening expressed sequence tags. The full-length complementary DNA of M. yessoensis CLP (My-Clp1) was 1555 bp in length, consisting of a 75-bp 5'-untranslated region (UTR), a 160-bp 3'-UTR, and a 1320-bp open reading frame bearing characteristics of the GH18 family. The My-Clp1 protein was well conserved, with similar domain structures and architecture across species (e.g., from mollusks to mammals). Expression analysis in healthy tissues and across developmental stages revealed a strong preference for expression; My-Clp1 was abundantly expressed in the mantle and throughout metamorphosis, which suggests the involvement of My-Clp1 in the synthesis of extracellular components, and tissue degeneration and remodeling. My-Clp1 expression was induced after infection with a bacterial pathogen, Vibrio anguillarum, suggesting its involvement in immunity against this intracellular pathogen.

Microsatellite markers derived from Japanese scallop (Mizuhopecten yessoensis) expressed sequence tags.

Japanese scallop (Mizuhopecten yessoensis) is a cold-water shellfish, and a species of economic importance in China. In this study, we developed and evaluated simple sequence repeat (SSR) markers from the expressed sequence tags (ESTs) of M. yessoensis. The characteristics of 12 EST-SSR loci were investigated in 30 individual scallops, and the result revealed that the number of alleles per locus ranged from 2-4, with an observed heterozygosity ranging from 0.0333-0.7692, and an expected heterozygosity ranging from 0.0333-0.6312. Only two loci were found to depart significantly from the Hardy-Weinberg equilibrium (P < 0.05). The result of our study suggested that these markers could be considered as potential markers for studying the population structure of M. yessoensis and its intraspecific variation.

[Clinical effect of modified vertical rectus abdominis myocutaneous flap in repairing skin and soft tissue defects after abdominoperineal resection for rectal cancer].

Objective: To investigate the clinical effect of the modified vertical rectus abdominis myocutaneous flap in repairing the skin and soft tissue defect after abdominoperineal resection for rectal cancer. Methods: This study was a retrospective observational study. From June 2019 to July 2022, five male patients with low rectal cancer who were conformed to the inclusion criteria were admitted to the Department of Basic Surgery of Xiangya Hospital of Central South University, with ages ranging from 65 to 70 years and the sizes of the perianal skin ulcers ranging from 5 cm×4 cm to 11 cm×9 cm, and all of them underwent abdominoperineal resection. The secondary skin and soft tissue defects in the perineum with an area of 8 cm×6 cm-14 cm×12 cm (with the depth of pelvic floor dead space being 10-15 cm) were repaired intraoperatively with transplantation of modified vertical rectus abdominis myocutaneous flaps with the skin area being 9 cm×7 cm-16 cm×12 cm, the volume of the muscle being 18 cm×10 cm×5 cm-20 cm×12 cm×5 cm, and the vessel pedicle being 18-20 cm in length. During the operation, most of the anterior sheath of the rectus abdominis muscle was retained, the flap was transferred to the recipient area through the abdominal cavity, the remaining anterior sheaths of the rectus abdominis muscle on both sides of the donor area were repeatedly folded and sutured, the free edge of the transverse fascia of the abdomen was sutured with the anterior sheath of the rectus abdominis muscle, and the donor area skin was directly sutured. After the operation, the survival of the transplanted myocutaneous flap was observed. The occurrence of complications in the perineal recipient area was recorded within 2 weeks after the operation. The recovery of the perineal recipient area and the abdominal donor area was observed during follow-up, and the occurrence of complications in the donor area of the abdomen as well as the recurrence of tumors and metastasis were recorded. Results: All transplanted myocutaneous flaps in 5 patients survived after surgery. One patient had dehiscence of the incision in the perineal recipient area 2 days after surgery, which healed after 7 d with intermittent dressing changes and routine vacuum sealing drainage treatment. In the other 4 patients, no complications such as incisional rupture, incisional infection, or fat liquefaction occurred in the perineal recipient area within 2 weeks after surgery. Follow-up for 6-12 months after discharge showed that the skin of the perineal recipient area had good color, texture, and elasticity, and was not bloated in appearance; linear scars were left in the perineal recipient area and the abdominal donor area without obvious scar hyperplasia or hyperpigmentation; no complications such as incisional rupture, incisional infection, intestinal adhesion, intestinal obstruction, or weakening of the abdominal wall strength occurred in the abdominal donor area, and the abdominal appearance was good with no localized bulge or formation of abdominal hernia; there was no local recurrence of tumor or metastasis in any patient. Conclusions: The surgical approach of using the modified vertical rectus abdominis myocutaneous flap to repair the skin and soft tissue defects after abdominoperineal resection for rectal cancer is relatively simple in operation, can achieve good postoperative appearances of the donor and recipient areas with few complications, and is worthy of clinical promotion.

Isolated skull cryptococcosis in an immunocompetent patient.

A 62-year-old immunocompetent rural woman who represents an isolated cryptococcal skull infection without systematic involvement is described. Diagnosis was based on positive India ink staining, positive histopathologic examination, and positive culture. Species identification was performed by growth on Sabouraud dextrose agar and CHROMagar medium and by sequencing of the intergenic and internal transcribed spacer regions of the rRNA genes. This case describes a rare presentation of Cryptococcus neoformans infection in a human immunodeficiency virus-negative patient. The lesions were significantly improved with treatment of daily oral itraconazole 400 mg. A maintenance therapy with a low-dose itraconazole was prescribed to warrant a clinical and mycological eradication. A two-year follow-up did not show any recurrence of infection.
