Safety and Efficacy of Oral Hydroxychloroquine in the Treatment of Ophthalmic Disease Associated with Sjögren's Syndrome.

Background: Dry eye disease is common among patients with primary Sjögren's syndrome (pSS). Hydroxychloroquine (HCQ), known for its immunomodulatory effects and minimal adverse effects, has emerged as a pivotal treatment option for pSS. Nonetheless, conflicting evidence exists regarding the therapeutic efficacy of HCQ in managing dry eye disease associated with pSS. Objectives: To evaluate the safety and efficacy of oral hydroxychloroquine in treating dry eye disease associated with pSS. Methods: A prospective randomized controlled study was conducted, enrolling pSS patients with moderate to severe dry eye disease. Participants were randomly assigned to an oral HCQ group and an observation group. Various scales (ESSDAI, ESSPRI, OSDI, and SPEED questionnaire score), dry eye-related tests (OSS score, TBUT, and Schirmer test I), ophthalmology-specific tests (BCVA, SD-OCT RT, field of view, latency and amplitudes for multifocal ERG ring 1 and ring 2), whole body protein levels (serum IgA, IgG, and IgM), and blood glucose were assessed before and after 12 months of treatment. Results: Pairwise comparison of the observed indicator baseline revealed no statistical significance (P > .05). After 12 months, the HCQ group exhibited notable improvements in ESSPRI, serum IgA, and Schirmer test I results compared to the control group (P < .05). Both groups demonstrated significant improvements in BCVA, OSDI, SPEED scores, and dry eye-associated examinations compared to baseline (P < .05). Serum IgG and IgM levels decreased in the HCQ group after 12 months of treatment, but without statistical significance (P > .05). None cases of HCQ retinopathy were reported during follow-up. Conclusions: Oral HCQ was demonstrated safety and efficacy in managing pSS-related dry eye disease. Treatment with Oral HCQ markedly reduced the ESSPRI score, improve patients' systemic dryness symptoms, and greatly decreased blood IgA levels. Combined with topical cyclosporin, HCQ improved Schirmer test I scores and alleviated ocular surface inflammation and dry eye signs and symptoms.

Research on ontology construction of acupuncture effect based on ISO/TS 16843-6: 2022 / 中国针灸

In order to specify the information expression of acupuncture effect and realize the knowledge reuse and sharing, in view of animal experiments and clinical trials, the relevant knowledge of acupuncture effect is allocated. Using seven-step method and Protégé5.5.0 tool, the ontology of acupuncture effect is constructed on the base of ISO/TS 16843-6: 2022. A total of 199 classes are constructed, including 7 categories (acupuncture point, acupuncture therapy, needling method, biological process, genes and gene products, disorder, and anatomic structure), 12 object properties, 1 108 instances and 5 123 axioms. A semantic network with the characteristics of acupuncture and moxibustion is established and the structured expression for the knowledge of acupuncture effects is obtained, which lays the foundation for the innovation and development in the field of acupuncture and moxibustion.

Automatic labeling and extraction of terms in natural language processing in acupuncture clinical literature / 中国针灸

The paper analyzes the specificity of term recognition in acupuncture clinical literature and compares the advantages and disadvantages of three named entity recognition (NER) methods adopted in the field of traditional Chinese medicine. It is believed that the bi-directional long short-term memory networks-conditional random fields (Bi LSTM-CRF) may communicate the context information and complete NER by using less feature rules. This model is suitable for term recognition in acupuncture clinical literature. Based on this model, it is proposed that the process of term recognition in acupuncture clinical literature should include 4 aspects, i.e. literature pretreatment, sequence labeling, model training and effect evaluation, which provides an approach to the terminological structurization in acupuncture clinical literature.

Experimental observation of effects of acupoints, cone numbers and durations of moxibustion with different moxibustion methods on skin surface and inside temperature / 针灸推拿医学（英文版）

Objective: To observe the effects of acupoints, cone numbers and durations of moxibustion with different moxibustion methods on skin surface and inside temperature, and to provide references for the clinical standardization of moxibustion amount. Methods: The 42 big-ear white rabbits were divided into 6 groups according to the random number table method, a 1-cone direct moxibustion group, a 2-cone direct moxibustion group, a 3-cone direct moxibustion group, a 1-cone herbal cake-partitioned moxibustion group, a 2-cone herbal cake-partitioned moxibustion group, and a 3-cone herbal cake-partitioned moxibustion group, with 7 rabbits in each group. Shenque (CV 8), Shenshu (BL 23) and Zusanli (ST 36) were used in each group, but the moxibustion methods, cone numbers and durations of moxibustion were different. Rabbits in each group received moxibustion once every other day for 5 times in total. During the intervention, a thermoelectricity coupled probe and a temperature recorder were used to record the real-time acupoint skin temperature and the temperature at different time points, so as to observe, analyze and process the real-time changes in the temperature difference between the surface and inside of acupoint skin. Results: For herbal cake-partitioned moxibustion, the best temperature for cone changing was (46.38±0.51) ℃ when the highest surface temperature was (49.20±0.52) ℃; the multi-factor comparison of acupoint × cone number × time and acupoint × moxibustion method × time showed that time × acupoint, time × moxibustion method and cone number × acupoint had interactive effects (all P<0.05). Comparing skin temperature differences between different cone numbers at the same acupoint, Shenque (CV 8) on the 1st and the 5th days, Shenshu (BL 23) on the 3rd and the 7th days, Zusanli (ST 36) on the 1st and the 9th days of experiment showed statistically significant differences (all P<0.05). The skin temperature comparison of different moxibustion methods at the same acupoint all had statistical differences (all P<0.05), except for Shenque (CV 8) before moxibustion, Shenshu (BL 23) before moxibustion and on the 5th day; Zusanli (ST 36) only showed statistical differences on the 5th and 7th days (both P<0.05). The skin temperature differences of different acupoints after moxibustion in the 1-cone, 2-cone and 3-cone groups were statistically different (all P<0.05); direct moxibustion and herbal cake-partitioned moxibustion at different acupoints were all statistically different (all P<0.05). Conclusion: Cone changing temperature under the same specifications of herbal cake-partitioned moxibustion was confirmed. Temperature difference between surface and inside of different acupoint skin at the same maximum temperature was significantly different due to the cone numbers and moxibustion methods, which showed the highest at Shenshu (BL 23), the second at Shenque (CV 8), and the lowest at Zusanli (ST 36). The influence of acupoint factor should be considered to determine the quantitative indicators of moxibustion.

Analysis of gene expression of Tetrahymena thermophila treated with Panax japonicas / 中国中药杂志

Panax japonicus is a traditional Chinese medicine,and its principle components have shown certain pharmacological activities for cell damage,aging and cell apoptosis. In order to clarify the pharmacological mechanism and involved metabolic pathways of P. japonicas,the gene expression of Tetrahymena thermophila under P. japonicus treatment was analyzed through high-throughput transcriptome sequencing in this study. Based on the transcriptome analysis,3 544 differentially expressed genes were identified in control group,of which 1 945 genes showed up-regulated expression and 1 599 genes showed down-regulated expression. Under P. japonicas treatment in the experiment group,3 312 differentially expressed genes were screened,of which 1 `493 genes showed up-regulated expression and 1 819 genes showed down-regulated expression. GO enrichment analysis indicated that in control group,the genes in the cells in a series of fundamental biological process were down-regulated,such as DNA replication and protein synthesis; while the signal transduction process and fatty acids oxidizing process were enriched. Whereas in the experiment group,down-regulated genes were mainly enriched in oxidation-reduction,cofactor metabolic process and vitamin metabolic process; up-regulated genes were enriched in signal transduction process and protein modification process. In the analysis using KEGG database,cell cycle pathway was enhanced and autophagy pathway was inhibited under the condition of P. japonicas treatment. Real-time quantitative polymerase chain reaction( RT-qPCR) was used to detect the expression differences between 6 up-regulated and 4 down-regulated genes in related metabolic pathways. The RT-q PCR results and RNA-Seq data were highly correlated and consistent with each other. This study could provide important direction and basis for further study on the mechanism of cell growth regulation with the treatment of P. japonica.

Nursing Intervention for Outpatient Rehabilitation in Pediatric Patients with Hirschsprung Disease after Colectomy.

OBJECTIVE: The present study was designed to evaluate the effectiveness of a nursing intervention program for outpatient rehabilitation of children with Hirschsprung-associated enterocolitis (HAEC) after radical colectomy for Hirschsprung disease (HD). BACKGROUND: Postoperative outcomes severely affect the quality of life in pediatric HD patients after operation. The improvement in defecation function is regarded as one of the most useful parameters to evaluate the quality of life in HD patients after radical intestinal resection. A close attention should also be paid to the patients' ability of social adaptation. METHODS: This prospective, randomized control trial enrolled 85 pediatric patients with HAEC after colectomy. They were randomly divided into the control and intervention groups. All the patients were followed up for 6 to 12 months after initial HAEC treatment. RESULTS: The intervention group had a lower enterocolitis recurrence rate than the control group, with a better ability to control defecation and their parents had better rehabilitation nursing knowledge (p < 0.05). The degree of parents' satisfaction regarding the outcome was significantly better in the intervention group than that in the control group (p < 0.05). CONCLUSION: A systemic rehabilitation nursing program could decrease enterocolitis recurrence, improve the recovery of anorectal functions, and enhance the quality of life in the pediatric patients after radical colectomy.

A new diagnostic scoring system to differentiate Hirschsprung's disease from Hirschsprung's disease-allied disorders in patients with suspected intestinal dysganglionosis.

PURPOSE: To create a simple diagnostic scoring system to differentiate Hirschsprung's disease (HD) from Hirschsprung's disease-allied disorders (HAD) in patients with suspected intestinal dysganglionosis (IDs). METHODS: Between 1998 and 2008, 967 patients with suspected intestinal dysganglionosis underwent surgical treatment at the pediatric surgery department of Tongji Hospital. The diagnosis of HD or HAD was confirmed by postoperative pathological examination. All patients underwent preoperative work-up including barium enema, anorectal manometry, and histochemical acetylcholinesterase staining of rectal mucosa. Known risk factors for IDs were recorded. The predicting score was calculated by summing the scores of the risk factors and three preoperative tests. The sensitivity, specificity, accuracy, positive predictive values, negative predictive values, positive likelihood ratios, and negative likelihood ratios of the predicting score were calculated. The cutoff score for predicting HD was determined using receiver operating characteristic (ROC) analysis. The accuracy of the predicting score was measured by the area under the ROC curve. RESULTS: Failed or delayed passage of meconium, age <3 years and male gender were risk factors associated with HD. The area under the ROC curve of the predicting score was 0.927 (95 % confidence interval, 0.910-0.944). A predicting score of more than 5 was used as a cutoff for predicting HD. The scoring system achieved 83.1 % sensitivity, 89.5 % specificity, and 85.9 % accuracy in predicting HD. CONCLUSION: Patients with a predicting score of more than 5 are more likely to be diagnosed with HD, whereas a score less than 5 are mostly indicative of HAD.

Traditional Chinese medicine intervention for stem cell transplantation in the treatment of cerebrovascular diseases / 中国组织工程研究

BACKGROUND:Stem cells under appropriate conditions can be induced to differentiate into neuron-like cells. Chinese herbs can function in cellproliferation and differentiation. OBJECTIVE:To investigate the interventional effects of traditional Chinese medicine on stem celltransplantation in the treatment of cerebrovascular diseases. METHODS:Experimental studies concerning traditional Chinese medicine intervention for stem celltransplantation were retrieved and analyzed. Under specific conditions, stem cells can proliferate in vitro in a suspended or monolayer manner, and can be potential y induced to differentiate into neurons, oligodendrocytes and astrocytes, thereby providing basis for stem celltransplantation in the treatment of cerebrovascular diseases. We observed expressions of nestin, glial fibril ary acidic protein, and microtubule-associated protein expression for analysis of stem cellproliferation and differentiation. RESULTS AND CONCLUSION:Baicalin or Astragalus saponin Ⅳ can stimulate stem cells to differentiate into nerve cells in vitro. Naomaitong or danshen combined with bone marrow mesenchymal stem celltransplantation can promote neurological recovery from cerebrovascular diseases in rats. Buyang Huanwu Decoction can significantly promote the proliferation of neural stem cells in the subventricular zone and neurological recovery after cerebral ischemia. Chinese herbs, such as Zhichan Decoction and Panax notoginseng, can promote survival of transplanted cells and prevent most cellapoptosis in the stem celltherapy for treatment of Parkinson’s disease. Therapy of benefiting qi and elevating yang or ginsenosides Rg1 combined with stem celltherapy can improve memory ability of dementia rats. Traditional Chinese medicine exerts a catalytic role in the stem celltherapy for cerebrovascular diseases.

Diagnosis and surgical treatment of isolated hypoganglionosis.

BACKGROUND: Some patients suspected with Hirschsprung's disease (HD), however, were diagnosed as having isolated hypoganglionosis according to the updated pathohistologic methods. This study was undertaken to investigate the diagnostic methods and the therapeutic results of isolated hypoganglionosis in children. METHODS: A retrospective analysis was made on 17 patients with isolated hypoganglionosis (hypoganglionosis group) identified pathologically after operation. The data included clinical presentations, barium enema, anorectal manometry, histochemical staining for acetylcholinesterase (AChE) before operation, histological results after operation and follow-up outcomes. The data of hypoganglionosis with HD (HD group) were compared retrospectively. RESULTS: Common complaint of the patients with hypoganglionosis and HD was intractable constipation. Barium enema showed typical narrowing and distended segment of the colon in 9 patients in the hypoganglionosis group (9/16) and in 15 patients in the HD group (15/18). In the hypoganglionosis group, in 15 patients who underwent anorectal manometry only 5 showed absent rectal anal inhibitory reflex, significantly lower than the rate in the HD group (17/18) (P<0.05). From 16 patients in hypoganglionosis group, positive staining for AChE was noted in 3 patients (3/16, 18.8%), significantly lower than that in the HD group (16/18, 88.9%) (P<0.05). Thirteen patients in the hypoganglionosis group received subtotal colectomy, while only 5 patients needed subtotal colectomy in the HD group. In the hypoganglionosis group, except 2 patients who suffered from mild enterocolitis after operation and recovered after conservative therapy, all patients recovered uneventfully without wound dehiscence, intestinal fistula, fecal incontinence or constipation recurrence. In the HD group, one patient suffered from anastomotic leak and got secondary operation, one patient had anastomotic stricture at 1 year after operation and recovered by dilatation, and other three patients suffered from mild enterocolitis after operation and recovered after conservative therapy. CONCLUSIONS: Hypoganglionosis is a common disease, and could be finally confirmed by full-thickness biopsies in different bowel segments. The resection range can be estimated according to barium enema and 24-hour delayed X-ray findings, by which the satisfactory result in short-term follow-up can be obtained.
