Objective:To explore the clinical efficacy and safety analysis of a novel laser localization technology assisted percutaneous puncture of trigeminal nerve microsphere capsule compression surgery for the treatment of primary trigeminal neuralgia.Methods:A retrospective selection was conducted on 63 patients with primary trigeminal neuralgia who underwent percutaneous puncture of the trigeminal nerve microsphere capsule compression surgery at the First Hospital of Hunan University of Chinese Medicine from January 2020 to December 2021. According to different surgical methods, they were divided into a new laser localization assisted puncture group (observation group) of 32 cases and a traditional barehanded localization puncture group (control group) of 31 cases. An analysis was conducted on the surgical time, puncture time, puncture frequency, intraoperative exposure to radiation, number of cases of poor balloon formation, and clinical efficacy within 6 months after surgery for two groups of patients. The prognosis of the patients was followed up at 6 months after surgery.Results:The surgical time, puncture time, puncture frequency, and intraoperative exposure of the observation group were all less than those of the control group, and the differences were statistically significant (all P<0.05). There was no statistically significant difference ( P>0.05) in the number of cases of poor balloon angioplasty between the observation group and the control group, as well as the pain score grading of the Barlow Neurological Institute (BNI) on the first day after surgery. Within 6 months after surgery, there was no statistically significant difference in the incidence of facial numbness, diplopia, masseter weakness, perilabial herpes, and recurrent pain between the two groups of patients (all P>0.05). Conclusions:Laser positioning technology can assist in precise puncture of the foramen ovale and accurate placement of balloons based on surgical experience, which helps to improve surgical safety, reduce postoperative complications and intraoperative radiation dose, and achieve satisfactory short-term follow-up results.

ObjectiveTo evaluate the clinical efficacy and safety of Tongluo Mingmu capsules in the treatment of diabetic retinopathy with blood stasis， collateral obstruction， and Qi and Yin deficiency syndrome. MethodA randomized， double-blind， positive-control， and multi-center clinical trial design method was used. 416 patients with diabetic retinopathy with blood stasis， collateral obstruction， and Qi and Yin deficiency syndrome in four test centers were included （the ratio of the treatment group to the control group was 3∶1）. On the basis of standardized hypoglycemic treatment， the treatment group was given both four Tongluo Mingmu capsules and two Calcium Dobesilate capsule agents three times a day， while the control group were given both two Calcium Dobesilate capsules and four Tongluo Mingmu capsule agents three times a day. The course of treatment was 12 weeks. The curative effect of Tongluo Mingmu capsules was evaluated by comparing the comprehensive curative effect of diabetic retinopathy， traditional Chinese medicine（TCM） syndrome score， corrected visual acuity， fundus changes， fundus fluorescence angiography， and other curative effect indexes before and after treatment in the two groups. At the same time， general examination， laboratory examination， and adverse events were performed to evaluate the safety of the drug. ResultThe baseline demographic data and disease characteristics of the treatment group and the control group were balanced and comparable， with the difference not statistically significant. After 12 weeks of treatment， the total effective rate of the comprehensive curative effect of diabetic retinopathy in the treatment group （61.0%， 189/310） was better than that in the control group （44.1%， 45/102）， and the difference was statistically significant （χ²=8.880， P<0.01）. The total effective rate of TCM syndromes in the treatment group （88.4%， 259/293） was better than that in the control group （69.9%， 65/93）， and the difference was statistically significant （χ²=17.927， P<0.01）. The disappearance rate of dry eyes （χ²=8.305）， dull complexion （χ²=4.053）， lassitude （χ²=10.267）， shortness of breath （χ²=8.494）， and dry stool （χ²=8.657） in the treatment group was higher than that in the control group， and the difference between the groups was statistically significant （P<0.05， P<0.01）. In terms of improving corrected visual acuity （χ²=8.382）， fundus changes （χ²=6.026） ， the treatment group was significantly better than the control group （P<0.05）. During the trial， the incidence of adverse events in the treatment group and the control group was 1.3% and 2.9%， respectively. There was no significant difference between the two groups. In addition， there were no serious adverse events and adverse events leading to withdrawal in both groups. ConclusionTongluo Mingmu capsules can improve the comprehensive curative effect of diabetic retinopathy and enhance the efficacy of TCM syndromes， visual acuity， fundus changes， and fundus fluorescein angiography， with great safety. Therefore， it can provide a new alternative therapeutic drug for patients with diabetic retinopathy.

Objective:To summarize the clinical phenotype and genetic characteristics of deficiency in ELF4 gene X-linked (DEX).Methods:A case series study was conducted to retrospectively analyze the clinical data and genetic testing results of 2 cases of DEX treated at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and the First Hospital of Jilin University from January 2023 to April 2024. And literature up to April 2024 was searched from the PubMed database, as well as CNKI and Wanfang databases, using keywords such as "ELF4 deficiency" "deficiency in ELF4, X-linked""ELF4 gene". The main clinical manifestations and genotypes of DEX were summarized.Results:Both patients were male, with onset ages of 3 months and 3 years, respectively. Both patients presented with recurrent oral ulcers and abdominal pain. And the laboratory examination showed a significant increase in inflammatory markers. Intestinal examinations showed multiple intestinal ulcers, and both patients developed intestinal fistulas. Whole exome sequencing found ELF4 c.799C>T, p Arg267Trp and ELF4 c. 248-7G>A, both maternal variants. Based on clinical and genetic results, DEX were diagnosed. In terms of treatment, both patients underwent surgical treatment during the acute phase of the disease and received anti-tumor necrosis factor α therapy, but recurrent gastrointestinal symptoms were still observed in Patient 1, while the clinical effect in Patient 2 was still acceptable. However, the inflammatory markers in both patients were not normal even after treatment. Literature review found 18 patients including 2 patients in this study, reported in 5 English articles and no Chinese reports. Thirteen patients had disease onset age before 5. The main clinical manifestations were fever (12/17), oral ulcers (14/18), abdominal pain (8/18), diarrhea (6/18), perianal ulcers (5/17), ileum ulcers (6/16), colon ulcers (7/16), skin involvement (7/17) and recurrent infections (7/18); laboratory examinations found increased erythrocyte sedimentation rate (13/15) as well as C-reactive protein (9/9), and anemia (13/15); in terms of immunological function, there is a decrease in natural killer cells (9/15) as well as a decrease in class switching memory B cells (8/9). The main types of gene variantions were missense variantions (6/18), nonsense variantions (4/18) or frameshift variantions (3/18).Conclusions:DEX should be considered when an early-onset male patient manifested with recurrent fever, oral ulcers or mucosal ulcers, with elevated inflammatory markers, with or without recurrent infection. It is recommended to perform lymphocyte subsets analysis, gastrointestinal endoscopy and genetic testing to support the diagnosis.
