Chinese Journal of Postgraduates of Medicine 2010;33(29):31-33
Objective To compare the effect of mini-incision cholecystectomy (MC) and laparoscopic cholecystectomy(LC). Methods Totally 168 patients with gallbladder disease were treated by cholecystectomy, they were divided into MC group (90 cases) and LC group(78 cases) using random digits table,and comparing the clinical effect between the two groups. Results The operating time was significantly shorter in MC group [(37.2 ± 12.3) win] than that in LC group [(51.6 ± 14.6) min](P<0.05). The length of stay and postoperative recovery time were (1.7 ± 1.1), (15.9 ± 3.2) d in MC group,(1.8 ± 0.9), (14.8 ± 4.9) d in LC group, there was no significant difference between the two groups (P>0.05). Body mass index had no influence to the operating time and postoperative recovery time. Conclusions With not complexity cholecystolithiasis, compared with LC, MC had shorter operating time, but no significant difference in postoperative recovery time. The MC procedure also seems to be suitable for the obese patients.

The distribution and morphology of 5-HT immunoreactive endocrine cells in the gastrointestinal tract of 5 adult rats were studied by the immunohistochemicael PAP method with nickel-intensified DAB on paraffin sections of intestine rolls. The density of 5-HT immunoreactive endocrine cells in the gastrointestinal tract of the rat is highest in the pylorus, duodenum and colon and moderate in the jejunum, ileum, caecum and rectum and lowest in the body of the stomach. The 5-HT immunoreactive endocrine cells are various in shape. Some of them have several processes extending between other epithelial cells. The basal portion of some endocrine cells have processes with 5-HT positive substance accumulating in their ends. The processes of the basal portion of some endocrine cells extend into lamina propria through the basal membrane. The 5-HT positive substance of many endocrine cells can be found to extend to luminal surface of the crypt or intestinal tract. These results indicate that the 5-HT immunoreactive endocrine cells can release 5-HT by both endocrine and exocrine ways.

The effects of hepatic ischemia/reperfusion (1/R) injuries on hepatocellular viability and store-operated calcium current (Isoc) in isolated rat hepatocytes and the effects of 2-APB on store-operated calcium current (Isoc) in isolated rat hepatocytes after hepatic ischemia/reperfusion injuries were studied. Hepatic ischemia and reperfusion injury model was established and whole cell patch-clamp techniques were used to investigate the effects of 2-APB on Isoc. The results showed that ischemia/reperfusion injuries could significantly reduce hepatocellular viability and further increase Isoc in hepatocytes and 2-APB (20, 40, 60, 80, 100 micromol/L,) produced a concentration-dependent decrease of Isoc with IC50 value of 64. 63 +/- 10.56 micromol/L, (n = 8). It was concluded that ischemia/reperfusion injuries could reduce hepatocellular viability, probably through increased Isoc in hepatocytes and 2-APB had a protective effect on ischemia/reperfusion-induced liver injury, probably though inhibiting Isoc.

Objective:To observe the efficacy of pars plana vitrectomy (PPV) in the treatment of different types of chorioretinal coloboma with retinal detachment (RD).Methods:A single-center, retrospective clinical study. From April 2021 to March 2023, 24 eyes of 23 patients who were diagnosed as chorioretinal coloboma with RD in Henan Provincial Eye Hospital were included in this study. There were 11 males with 12 eyes and 12 females with 12 eyes. The mean age was (33.3±13.7) years old. Best corrected visual acuity (BCVA), spectral domain optical coherence tomography were performed. The BCVA examination was performed using a international standard logarithmic visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. According to the types of chorioretinal coloboma, the affected eyes were divided into the coloboma involved the optic disc group and the coloboma not involved the optic disc group, with 15 eyes and 9 eyes. According to whether the RD containing the coloboma area, the affected eyes were divided into RD containing the coloboma area group and the RD not containing the coloboma area group, with 15 eyes and 9 eyes. All eyes underwent standard pars plana three-channel 25G PPV, retinal laser photocoagulation combined with silicone oil tamponade. The follow-up time after surgery was (19.5±16.3) months. The last follow-up was the time point for efficacy determination. The retinal reattachment, BCVA recovery and postoperative complications were observed. Paired t-test or t test was performed for comparison of quantitative data. Fisher's exact test was performed for comparison of qualitative data. Results:At the last follow-up, retinal reattachment was achieved in 20 eyes (83.3%, 20/24). The logMAR BCVA of the coloboma involved the optic disc group before and after surgery were 1.85±0.62 and 1.71±0.71, the difference was no significant ( t=0.845 , P=0.412). The logMAR BCVA of the coloboma not involved the optic disc group before and after surgery were 1.75±0.45 and 0.84±0.26, the difference was statistically significant ( t=6.153 , P<0.001). The improvement of BCVA in the coloboma not involved the optic disc group was significantly higher than that in the coloboma involved the optic disc group after surgery, with statistically significant differences ( t=3.024 , P=0.006). There was no significant difference in the retinal reattachment rate between the two groups ( P=0.615). There was no significant difference in the retinal reattachment rate between the RD containing the coloboma area group and the RD not containing the coloboma area group ( P=0.259). Postoperative complications included elevated intraocular pressure in five eyes, cataract progression in ten eyes, recurrent RD in two eyes, bullous keratopathy in one eye and band-shaped keratopathy in one eye. Conclusion:PPV combined with silicone oil tamponade is safe and effective in the treatment of chorioretinal coloboma with RD, the improvement of visual acuity in the coloboma not involved the optic disc group is better than that in the coloboma involved the optic disc group after surgery.

Objective:To analyze the clinical manifestations and explore the etiology in a family with congenital aniridia and to analyze the influence of candidate variants on the protein structure.Methods:A pedigree investigation was performed.A Han Chinese family with congenital aniridia of two generations consisting of three members from Henan Province, including one patient diagnosed with congenital aniridia, was identified and studied following their admission to Henan Eye Hospital in June 2023.A thorough medical history was obtained for the patient and their family members.Comprehensive ophthalmologic examinations were conducted, including visual acuity, intraocular pressure, anterior segment photography, color fundus photography, ultrasound biomicroscopy, and optical coherence tomography, etc.Peripheral blood samples were obtained from the family members and whole exome sequencing (WES) was performed on the patient and validated by Sanger sequencing for other members.The pathogenicity and protein structure of newly identified variant sites were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2023[06]).Written informed consent was obtained from each subject.Results:The proband is a 23-year-old male presenting with poor binocular vision, aniridia, corneal degeneration, mild lens opacity, shallow anterior chamber, elevated intraocular pressure, peripheral retinal degeneration, and macular dysplasia.The clinical phenotype of the proband's parents did not show any significant abnormality.WES identified a heterozygous frameshift and nonsense varint c. 734_735del (p.Arg245Asnfs*20) in exon 10 of the PAX6 gene, which consisited of two bases deletion at positions 734 to 735, resulting in the mutation of its arginine at position 245 to asparagine and the early appearance of a termination codon at the next 19 amino acids.The variant had not been identified in the HGMD, Clinvar, 1 000 Genomes, and gnomAD databases.Neither of the proband's parents carried the variant, consistent with the pattern of family co-segregation.Substructural analysis using the SMART tool indicated that the variant is situated within the HOX domain.Amino acid conservation analysis demonstrated that the arginine residue at position 245 in the PAX6 gene is highly conserved across multiple species, including human, house mouse, domestic dog, African clawed frog, and macaque.The variant was classified as pathogenic (PVS1+ PS2+ PM2+ PP3) based on the ACMG standards and guidelines for the interpretation of sequence variants.Protein structure analysis revealed the absence of both the homologous domain and the proline-serine-threonine-rich domain in the PAX6 protein. Conclusions:A novel pathogenic variant, c.734_735del (p.Arg245Asnfs*20), in the PAX6 gene has been identified in a family affected by congenital aniridia.This variant results in the deletion of both the PAX6 protein homology domain and the proline-serine-threonine-rich domain.
