Objective:To explore the feasibility and effect of applying spherical fitting technology in CT three-dimensional reconstruction in preoperative planning of the resection range of Cam-type femoral acetabular impingement (FAI).Methods:46 Cam-type FAI patients who underwent arthroscopic femoroplasty in the Department of Sports Medicine in the Third Affiliated Hospital of Southern Medical University from July 2020 to June 2022 were enrolled in the spherical fitting group, including 26 females and 20 males, with an average age of 38.4±15.2 years (range of 24-53 years). The preoperative planning was performed using spherical fitting technology in CT three-dimensional reconstruction. Another 42 Cam-type FAI patients who underwent arthroscopic femoroplasty from July 2018 to June 2020 were enrolled in the observation group, including 25 females and 17 males, with an average age of 43.6±18.4 years (range 24-61 years). The preoperative planning was performed using CT three-dimensional reconstruction observation method. This study evaluated the impact of femoroplasty planned by spherical fitting technique on patients' prognosis though comparing the differences of postoperative α angle, femoral head-neck offset ratio, modified Harris hip score (mHHS), and visual analog score (VAS) at 3, 6, 9, and 12 months between two groups.Results:The average follow-up time was 11.8±0.6 months in spherical fitting group and 11.3±0.8 months in observation group. There was no significant difference regarding α angle, femoral head-neck offset ratio, mHHS, and VAS between two groups preoperatively ( P>0.05). The mHHS in two groups increased gradually, while VAS decreased sequentially at 3, 6, 9, and 12 months postoperatively. The postoperative mHHS and VAS were significantly better than those before surgery ( P<0.05). The mHHS was 83.2±14.8 vs. 70.5±11.2 in spherical fitting group and observation group at the followup of 9 months with significant difference ( t=4.471, P=0.007). It was 85.7±13.3 vs. 73.2±12.5 at the followup of 12 months with significant difference ( t=4.596, P=0.008). No significant difference was found in α angle, femoral head-neck offset ratio or mHHS at 3 and 6 months postoperatively ( P>0.05), and no significant difference was found in VAS at 3, 6, 9, and 12 months postoperatively between two groups. Conclusion:The spherical fitting technology in CT three-dimensional reconstruction could assist surgeons with planning of the resection range of Cam deformity preoperatively, and achieve a smooth progress of arthroscopic femoroplasty intraoperatively; after short term follow-up, we found that patients who underwent femoroplasty using this technology achieved satisfactory outcomes.

Objective:To investigate the application of virtual reality (VR) technology on intraoperative pain in patients undergoing peritoneal dialysis (PD)-related procedures with local infiltration anesthesia and the satisfaction.Methods:It was a single-center, prospective, concurrent controlled study. Patients were divided into two groups: VR group and control group. In the VR group, patients wore a VR headset to watch soothing audio and video content during surgery, while the control group underwent routine procedures. Intraoperative pain and satisfaction were assessed using the visual analog scale (VAS) and a 5-point satisfaction scale within 30 minutes of surgery. In addition, tolerance of the VR experience in the VR group was assessed using the VR sickness questionnaire.Results:A total of 43 patients were included in the study, including 25 males (58.1%). Chronic glomerulonephritis [17 cases (39.5%)] and diabetic nephropathy [6 cases (14.0%)] were the main primary diseases. There were 23 cases in the control group and 20 cases in the VR group. There were no significant differences between the two groups in age, sex ratio, proportion of primary disease, diabetes, hypertension, distribution of operation methods, preoperative vital signs and operation time (all P>0.05). VAS pain score was significantly lower in the VR group than that in the control group (5.90±2.38 vs. 7.43±1.67, t=2.469, P=0.018). The percentage of patients who were satisfied was 89.5% (17/19) in the VR group and 78.3% (18/23) in the control group, but there was no significant difference (chi-square test for continuity correction, χ2=0.308, P=0.579). Three patients in the VR group withdrew from the study due to severe discomfort, while the remaining participants found the VR experience to be tolerable. Common adverse effects included fatigue and blurred vision. Conclusions:The application of VR technology in PD-related procedures has been effective in reducing intraoperative pain when combined with local infiltration anesthesia. Furthermore, the utilization of VR technology in PD-related procedures is associated with a safe and tolerable outcome, despite the observation of some adverse effects.

ObjectiveTo investigate the effects of Huashi Runzao prescription (HRP) on the histopathological injury and function of submandibular gland in naive non-obese diabetic (NOD/Ltj) mouse model of Sjögren's syndrome (SS) and its regulatory effect on aquaporin 5 (AQP5) expression in submandibular gland cells. MethodThe SS model was induced in NOD/Ltj mice. The NOD/Ltj female mice aged nine weeks were selected and randomly assigned into model group,HRP group (7.15 g·kg-1·d-1),and hydroxychloroquine (HCQ) group (1.30 g·kg-1·d-1), and female BALB/c mice in the same age were selected and assigned into the normal group, with six mice in each group. Drug intervention lasted eight weeks. The water consumption and salivary flow rate (SFR) of each group were recorded. The pathological staining results of the submandibular gland of mice in each group were observed and scored. AQP5 expression was determined by immunohistochemistry (IHC) and Western blot. ResultCompared with the normal group, the model group showed increased water consumption (P<0.05) and reduced SFR (P<0.05). Compared with the model group, the HRP group showed decreased water consumption (P<0.05) and increased SFR (P<0.05), and the HCQ group showed increased SFR (P<0.05). In terms of histopathological results of the submandibular gland,compared with the normal group,the model group showed increased pathological score, number of lymphocyte infiltration foci,and percentage of lymphatic infiltration area (P<0.05). Compared with the model group, the HRP group showed reduced pathological scores and number of lymphocyte infiltration foci (P<0.05), and the HRP group and the HCQ group showed reduced percentage of lymphatic infiltration area(P<0.05). The results of IHC and Western blot showed that compared with the normal group,the model group showed down-regulated expression level of AQP5 protein (P<0.05), and compared with the model group and the HCQ group,the HRP group showed up-regulated expression level of AQP5 protein (P<0.05). ConclusionHRP can improve the secretion function of submandibular gland acinous cells and glandular structure injury in SS model mice, and its mechanism may be related to the up-regulation of AQP5 protein expression level in submandibular gland cells.

ObjectiveTo observe the efficacy and safety of Huashi Runzao prescription for patients with primary Sjögren's syndrome (pSS) of combined dryness and dampness pattern. MethodA total of 105 eligible patients were randomized into the experimental group (65 cases) and control group (40 cases), and they were respectively treated with Huashi Runzao prescription and hydroxychloroquine for 12 weeks. Visual Analogue Scale (VAS) was employed to assess the symptoms. The symptoms of dryness, fatigue, and pain, European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI), EULAR Sjögren's syndrome disease activity index (ESSDAI), and immune inflammatory indicators before and after treatment were compared between the two groups, and adverse reactions were observed. ResultAfter treatment, the ESSPRI score was lower than that before treatment in the experimental groups (P<0.01) and was lower in the experimental group than in the control group (P<0.05). The VAS scores of dry mouth, dry eyes, overall dryness, fatigue, and pain in the experimental group decreased compared with those before treatment (P<0.01), and the experimental group had lower VAS scores of dry mouth and overall dryness than the control group (P<0.01). After treatment, the ESSDAI score of both groups decreased compared with that before treatment (P<0.05, P<0.01), but there was no significant difference between the groups. After treatment, the level of immunoglobulin M (IgM) decreased (P<0.01) and the level of complement C3 increased (P<0.01) in the experimental group, while the level of complement C3 decreased in the control group (P<0.05). There was no significant difference in the laboratory indexes between groups. During the treatment, stomachache occurred to one case in the experimental group, which was alleviated after the treatment, and no adverse reaction was observed in the control group. According to the chi-square test, the occurrence of adverse reactions was insignificantly different between the two groups. ConclusionHuashi Runzao prescription can alleviate the symptoms of dryness, fatigue, and pain, and reduce disease activity without associated side effects in pSS patients with combined dampness and dryness pattern.

ObjectiveTo explore the characteristics of tongue manifestations and traditional Chinese medicine (TCM) syndromes in patients with primary Sjogren's syndrome (pSS) of different time. MethodpSS patients who visited TCM Department of Rheumatism in China-Japan Friendship Hospital from December 2018 to October 2021 were included and grouped according to the disease courses (short<5 years, medium 5-10 years, long > 10 years). Chi-square test was used for comparison between three groups and Bonferroni method for multiple comparisons. In the pairwise comparison, P<0.017 indicated significant difference. Chi-square test was performed on the syndrome and specific tongue manifestations with inter-group differences to analyze the trend of tongue manifestations and TCM syndromes over time (interval: two years). ResultA total of 193 pSS patients were enrolled, with 85 (44.0%) of short disease course, 69 (35.8%) of medium disease course, and 39 (20.2%) of long disease course. The common tongue manifestations were crimson tongue, fissured tongue, thin tongue, lack of fluid, and dry coating, which showed no significant difference among the three groups. Higher proportion of patients with light red tongue was observed in the group with short disease course than in group with medium disease course (χ2=6.407, P<0.017). Higher proportions of patients with thick coating (χ2=6.784, P<0.017) and phlegm-dampness syndrome (χ2=11.545, P<0.017) and lower proportion of patients with Qi deficiency syndrome (χ2=12.706, P<0.017) were found in the group with short disease course than in the group with long disease course. Patients with medium (χ2=6.358, P<0.017) and long (χ2=8.279, P<0.017) disease course tended to have exfoliated coating compared with those with short disease course, and the proportion of patients with exfoliated coating rose and the proportion of patients with thick greasy coating decreased over time (Ptrend<0.05). In addition, the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time (Ptrend<0.05). ConclusionIn the early stage, patients with pSS often show both dryness and dampness, as manifested by the thick greasy coating and phlegm-dampness syndrome. In the medium and late stage, patients often have Qi-Yin deficiency, as evidenced by exfoliated coating and Qi deficiency. In the clinical practice, medicines should be prescribed based on tongue manifestations and TCM syndrome of patients.

ObjectiveTo analyze the clinical characteristics of geographic tongue in patients with primary Sjögren's syndrome (pSS). MethodPatients with pSS treated in the China-Japan Friendship Hospital from December 2018 to October 2021 were enrolled and divided into different groups according to the presence of geographic tongue or the severity. Phi correlation analysis,Chi-square test, and Mann-Whitney test were used to analyze the clinical characteristics of patients with geographic tongue. ResultA total of 182 pSS patients were included in this study,including 75 (41.2%) patients with geographic tongue and 107 (58.8%) without geographic tongue. Partial exfoliation was more common than total exfoliation, and the anterior part of the tongue was the most common exfoliation site. The number of patients with severe geographic tongue was more than those with mild-to-moderate geographic tongue. Compared with pSS patients without geographic tongue,those with geographic tongue were more common in fissured tongue (92.0%/41.1%,χ2=48.491,P<0.05),red or crimson tongue (48.0%/23.3%,χ2=12.009,P<0.05),Yin deficiency syndrome (100.0%/43.9%,χ2=62.739,P<0.05),and Qi deficiency syndrome (94.7%∶50.5%,χ2=40.046,P<0.05),less common in phlegm-dampness syndrome (33.3%/72.0%,χ2=26.709,P<0.05),and showed higher proportions in hyperglobulinemia (89.3%/65.4%,χ2=13.547,P<0.01),ANA ≥1∶160 (78.1%/57.3%,χ2=8.227,P<0.01),and positive RF (51.4%/36.5%,χ2=3.877,P<0.05). Compared with pSS patients with mild geographic tongue,pSS patients with moderate-to-severe geographic tongue had higher proportions in hyperglobulinemia (98.1%/68.2%,χ2=14.617,P<0.01),positive anti-CENP-B (26.0%/4.8%,χ2=4.214,P<0.05),and reduced complement 3 (26.4%/4.5%,χ2=4.647,P<0.05). The geographic tongue was positively associated with fissured tongue (φ=0.531),Yin deficiency syndrome (φ=0.587),and Qi deficiency syndrome (φ=0.469),negatively associated with phlegm-dampness syndrome (φ=-0.447),and weakly associated with tongue color (φ<0.4). There was no statistical difference in the disease activity index between patients with or without geographic tongue and severity. ConclusionMore than 40% of pSS patients had geographic tongue accompanied by fissured tongue. Geographic tongue is positively associated with Yin deficiency syndrome and Qi deficiency syndrome,and negatively associated with phlegm-dampness syndrome, indicating that treatment should be based on tonifying Qi and nourishing Yin. Compared with pSS patients without geographic tongue, those with geographic tongue may have higher positive rate of some immune indicators,which deserves further exploration.
