Objective:To detect the factors related to hemocytopenia and interstitial lung disease (ILD) secondary to primary Sj?gren's syndrome (pSS) in in-patients.Methods:Clinical characteristics of patients with pSS hospitalized in China-Japan Friendship Hospital from March 2014 to October 2020 were retrospectively analyzed. Patients were divided into different groups according to hemocytopenia and ILD. Chi-square test and Mann-Whitney U test were used to compare data in subgroups, and logistic regression were used to detect factors related to hemocytopenia and ILD secondary to pSS. Results:Five hundred and seventy-one inpatients with pSS were included in this study and the female: male ratio was 8∶1. Two hundred and seventy five of included patients had hemocytopenia (48.2%) and 180 patients had ILD (31.5%). Compared with patients without hemocytopenia, patients with hemocytopenia had higher ratio in low C3 [ OR=2.326, 95% CI(1.483, 3.650), P<0.01] and elevation of erythrocyte sedimentation rate (ESR) [ OR=1.912, 95% CI(1.233, 2.964), PP<0.01) . Compared with patients without ILD, patients with ILD showed higher ratio in male[ OR=2.509, 95% CI(1.269, 4.959), P<0.01) and fatigue [ OR=5.190, 95% CI(5.190, 13.931), P<0.01) , lower positive rate of anti-SSA antibody [ OR=0.392, 95% CI(0.230, 0.668), P<0.01) and anti-CENPB [ OR=0.337, 95% CI(0.145, 0.782), P<0.01] antibodies, and lower ratio in low C3[ OR=0.332, 95% CI(0.189, 0.582), P<0.01]. Conclusion:Low C3 and high ESR may be risk factors for developing hemocytopenia in patients with pSS. Men with pSS may be susceptible to ILD, while pSS patients with ILD may have lower ratio in positive anti-SSA antibody, positive anti-CENPB antibody and low C3. All of these findings are yet to be validated by future prospective cohort studies.

Objective:To explore the neural mechanism of language dysfunction in patients with subacute stroke using functional near-infrared spectroscopy (fNIRS).Methods:Sixteen patients with non-fluent aphasia after subacute stroke (aphasia group), 16 patients with non-aphasia after stroke (non-aphasia group), and 16 healthy middle-aged and elderly subjects (control group) were enrolled into our study. The 6-min resting-state data of fNIRS were collected. Four language-related regions, Broca area, Wernicke area, dorso lateral prefrontal cortex (DLPFC), and supplementary motor area (SMA), were selected as regions of interest (ROIs), and the whole brain functional connection strength and functional connection strength in ROIs and between each two ROIs were analyzed by NirSpark software.Results:Compared with the control group (0.53±0.15) and non-aphasia group (0.47±0.12), the aphasia group had significantly decreased whole brain functional connection strength (0.29±0.14, P<0.05). Compared with the control group and non-aphasia group, the aphasia group had significantly decreased functional connection strength in the left Wernicke area, right Wernicke area, left Broca area, left SMA area, right SMA area and left DLPFC area ( P<0.05, FDR). Compared with the control group and non-aphasia group, the aphasia group had significantly decreased functional connection strength in the right Wernicke-left Wernicke area, right Wernicke-right Broca area, right Wernicke-left Broca area, right Wernicke-right DLPFC area, right Wernicke-left DLPFC area, right Wernicke-right SMA area, right Wernicke-left SMA area, left Wernicke-right Broca area, left Wernicke-left Broca area, left Wernicke-right DLPFC area, left Wernicke-left DLPFC, left Wernicke-right SMA area, left Wernicke-left SMA area, right Broca-left Broca area, right Broca-left DLPFC area, right Broca-right SMA area, right Broca-left SMA area, left Broca-right DLPFC area, left Broca-left DLPFC area, left Broca-right SMA area, left Broca-left SMA area, right DLPFC-left DLPFC area, right DLPFC-right SMA area, right DLPFC-left SMA area, left DLPFC-right SMA area, left DLPFC-left SMA area, and right SMA-left SMA area ( P<0.05, FDR). Conclusion:Abnormal functional connectivity strength of the whole brain and language-related key brain areas might be the neural mechanism of language dysfunction in patients with non-fluent aphasia after subacute stroke.

Objective:To investigate the method and clinical effect of ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm.Methods:From January 2017 to December 2019, 71 patients in Gongren Hospital with femoral pseudoaneurysm were treated by ultrasound-guided thrombin injection. There were 55 cases of fistula type and 16 cases of fissure type. The maximum diameter of the cavity and the neck of pseudoaneurysm were measured and recorded. Two groups of patients were injected thrombin under ultrasound guidance (according to the shape of the pseudoaneurysm neck, different injection methods were used). The treatments for the first time and first recurrence of the two groups were treated with the corresponding conventional injection method. For the second fracture type of the second recurrence of the patients, the method of cross injection and gradual advance to the pseudoaneurysm neck was used for the third time, and the compression time was extended after the blood flow in the cavity disappeared. Ultrasound was performed at 24 hours and 1 week after operation to observe the blood flow and thrombosis.Results:In 55 patients with pseudoaneurysm of fistula type, 54 patients were treated successfully after once injected, pseudoaneurysm recurred in 1 patient relapsed by ultrasound 24 hours after operation, and the second injection was successful. In 16 patients with pseudoaneurysm of fissure type, 10 patients were successfully treated after once injection, 6 patients recurred 24 hours after operation, 4 patients were successfully treated after the second injection, and 2 patients after the third injection. There was no correlation between the recurrence of fistula pseudoaneurysm and the diameter of the pseudoaneurysm neck( r s=0.103, P=0.455), while the recurrence of fissure pseudoaneurysm was closely related to the diameter of the pseudoaneurysm neck( r s=0.870, P<0.001). Finally, all the patients achieved satisfactory curative effect, and the cure rate was 100%. Conclusions:Ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm has a significant clinical effect. However it is necessary to determine the shape of the pseudoaneurysm neck and measure the diameter of the pseudoaneurysm neck before operation, so as to adopt a reasonable and effective injection method, to improve the success rate of the first treatment and reduce the recurrence.

Objective: To discuss the application of plane-shaped flaps for reconstruction of the web space in polysyndactyly of the fifth toe fused with the fourth toe. Methods: A total of 62 cases (81 feet) with polysyndactyly of the fifth toe fused with the fourth toe were involved in the study, 53 of which were incomplete and 9 were complete fusion of the fourth and fifth toe. The fifth toe showed various degrees of fibular clinodactyly and minor deformities. Excision of polydactyly and then using arthroplasty or osteotomy correction deviation was for fibular clinodactyly. All plane-shaped flaps were used for reconstruction of the web space deeply, and the lateral sides of toes were closed with flaps and the distal soft tissues of polydactyly were used lengthening the reconstructed fifth toe. Brachydactylias were improved, and nail folds were reconstructed. Thus, the appearances reached the normal level. Results: All the webs were reconstructed primarily without skingraft. After 12 months of follow-up, these reconstructed web space were satisfied with good appearances of width, depth and gradient. The fibular clinodactyly was completely corrected, and brachydactylias were corrected in various degrees. Nail folds reached the normal ones. Conclusions Plane-shaped flap in polysyndactyly of the fifth toe fused with the fourth toe for reconstruction of the web space is satisfactory. The reconstructed webs not only achieves good appearance, but also avoids skin grafts. It is one of the best choices of the polysyndactyly treatment.

Objective:To investigate the effects of superoxide dismutase 1 (SOD1) mutations G41D and G41S on the cognitive behavior of mice.Methods:The recombinant adeno-associated virus (rAAV) which overexpressed human SOD1WT, SOD1G41S, SOD1G41D and the blank virus without the target gene were constructed, then they were stereotaxic injected into mice bilateral medial prefrontal cortex (mPFC) area respectively.According to the difference of injected virus, they were divided into CONTROL group, SOD1WT group, SOD1G41S group and SOD1G41D group ( n=16 in each group). One month later, open field test, Y-maze spontaneous alternation experiment, three box social interaction experiment and trace fear conditioning test were conducted to observe the effect of mutant gene on cognitive behavior of mice. Results:In the open field test, the movement distance of SOD1WT group((39.67±6.04)m)was significantly higher than that of SOD1G41D group((28.47±6.92)m, P=0.034). In the Y-maze spontaneous alternations experiment, the number of arm entries and actual alternations of arm entries of SOD1WT group((40.56±10.12)times, (32.63±8.19)times)and SOD1G41S group((36.75±9.43)times, (29.06±8.32)times)were significantly higher than those of SOD1G41D group((24.50±11.30)times, (18.38±9.09)times, P<0.05). In the three-compartment social experiment, there was no statistical difference between the residence time of SOD1G41D group in the area containing mouse ((279.08±134.94) s) and the empty metal cage area ((218.54±125.63) s) ( t=1.313, P=0.199). SOD1WT group and SOD1G41S group showed no statistical difference in the residence time in the regions of the unfamiliar mouse 1((253.07±55.60)s, (253.20±57.61)s) and the unfamiliar mouse 2 ((243.44±55.33) s, (239.76±67.49) s) ( P>0.05), and SOD1WT group and SOD1G41S group presented new social barrier.In the test stage of trace fear condition task, the percentage of freezing time of SOD1G41S group was significantly higher than that of other experimental groups and CONTROL group ( P<0.05). Conclusion:SOD1G41S and SOD1G41D have significantly changed the cognitive behavior of mice, and the two types of mutations at the same site have significant differences in the cognitive behavior changes.

Conclusion:Women with pSS present a higher ratio in dry mouth, dry eyes, leukocytopenia and positive autoantibodies than men, while parotid enlargement and ILD are more common in men than women. Young patients are prone to renal involvement, middle-aged patients are prone to arthralgia, while elderly patients are prone to dental caries and xerophthalmia. With the growth of age, the positive rates of autoantibodies and elevated IgG are decreased gradually in patients with pSS, but the ratios of dental caries, xerophthalmia and ILD is increased gradually.

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.
