OBJECTIVE Hypericin, a powerful naturally photosensitizer in photodynamic therapy (PDT), is suitable for treating skin diseases involving excess capillary proliferation. In the present study, we aimed to evaluate the skin penetrability of a topically applied hypericin, expecting reducing the risk of prolonged skin photosensitivity, which often occurs after systemic administration. METHODS The Franz diffusion cell assay was performed to evaluate different penetration enhancers. In vivo studies, fluorescence microscopy was performed to examine the distribution of hypericin in the skin, macroscopic and microscopic analyses were also carried out to detect pathological changes in the skin after topical hypericin-PDT treatment. Immunohistochemistry was used to determine the expression of PECAM-1 in the treated skin. RESULTS 5% menthol facilitated hypericin penetrate the skin of nude mice most. The results of in vivo assays revealed that hypericin penetrated nude mice skin, spread to the dermis, and resulted in obvious photosensitivity reaction on the dermal capillaries. Moreover, skin injured by the photosensitive reaction induced by hypericin was replaced by normal skin 7 d after hypericin-PDT treat?ment. CONCLUSION Topical hypericin could penetrate nude mouse skin well and be great potential in PDT treatment of skin diseases.

Objective To identify risk factors for a human orf disease outbreak in a village in Chongqing city. Methods Standardized case-definition was set and a case-finding program was conducted among all the residents of the village. All the patients were interviewed using a standardized questionnaire and collected fluids in the skin rash for laboratory testing. A retrospective cohort investigation was conducted among all the village residents who introduced the black goats to analyze the risk of orf infection, in relation to the mode and frequency of contacts to the infected goats. Results We found 18 cases (including 16 suspected cases and 2 confirmed cases) among the members of 10 families that introduced the black goats. Village residents who had ever used their legs to grip the goats were nearly five times as likely to develop orf disease as those who did not (RR=4.98, 95%CI: 1.34-75.27). Village residents who had ever washed and wiped the goats were three times as likely to develop orf disease as those who had not (RR = 3.09,95%CI: 0.98-45.38). The frequency of contacts with the infected goats was associated with the risk of developing orf disease in a dose-response fashion (x2 test for trends: P= 0.006).Frequently wearing long trousers when dealing with the goats appeared as a protective factor (RR=0.30,95%CI: 0.15-0.78). Conclusion This outbreak was caused by the introduced black goats which carried and infected by the orf virus. Direct physical contact with infected goats but without wearing protective clothing were risk factors for the development of human orf disease.

Objective:To evaluate the clinical and radiographic outcomes of tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach.Methods:From March 2018 to February 2021, 23 patients underwent tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach at the Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital.Of them, 15 were males and 8 females. Their average age at surgery was 54.4 years (range, from 28 to 72 years). There were 11 cases of traumatic arthritis, 2 cases of Charcot arthropathy, 6 cases of neurogenic equinovarus, 2 cases of traumatic equinovarus, and 2 cases of Kashin-Beck disease. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), visual analogue scale (VAS), foot function index (FFI), hindfoot alignment angle (HA), hindfoot alignment distance (HD), and hindfoot alignment ratio (HR). The tibia-foot angle on lateral weight-bearing and patient satisfaction at the last follow-up and postoperative complications were documented.Results:This cohort were followed up for an average of 24.7 months (from 12 to 48 months). The AOFAS ankle-hindfoot score (78.2 ± 9.2), VAS [2.0 (0.5, 2.0)], FFI [19.0 (10.5, 35.0)], HA (2.7° ± 5.8°), HD [(0.1 ± 0.8) cm] and HR [44.2 (36.4, 59.2)%] at the last follow-up were significantly improved than the preoperative values [43.4 ± 12.7, 4.0 (4.0, 6.0), 98.0 (60.0, 127.0), 22.0° ± 14.3°, (2.2 ± 1.6) cm and 86.0 (66.3, 100.0)%] (all P<0.05). The tibia-foot angle on lateral weight-bearing was 89.0° (87.1°, 90.4°) at the last follow-up. By the Likert scale, 17 cases were very satisfied with the surgery, 4 cases satisfied and 2 cases tolerate, giving a satisfaction rate of 91.3%(21/23). Infection occurred in one case and nonunion in one. Conclusion:Tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach yields good mid- to short-term clinical and radiographic outcomes, showing a strong capability to correct ankle and hindfoot varus and equinus.

BACKGROUNDTransplanting a vascularized autologous submandibular gland (SMG) is considered an effective method to treat severe keratoconjunctivitis sicca. But the operation may fail due to the anatomic variances in the blood vessels of SMG. The present study aimed to investigate the submandibular glands at the microanatomy level.
METHODSThe microanatomy of blood vessels including arteries and veins of submandibular gland was investigated using 30 adult corpses and 60 submandibular glands were anatomized under a surgical microscope. The lengths and diameters of the arterial and venous glandular branches were measured using sliding caliper.
RESULTSThe submandibular gland was mainly supplied by the facial artery and submental artery, partly by the lingual artery and external jugular artery. The venous drainage of the submandibualr gland occurred through the anterior facial vein, the venae comitantes of facial artery, the vein close to the Whaston's duct (the hilum vein), and seldom drained to external jugular vein and other veins.
CONCLUSIONSThe anatomy of SMG is a complicated structure. Determining the main blood vessels of the submandibular gland is very important to achieve a successful vascularized autologous SMG transplant.

BACKGROUNDTricuspid regurgitation (TR) is frequently associated with severe mitral stenosis (MS), the importance of significant TR was often neglected. However, TR influences the outcome of patients. The aim of this study was to investigate the efficacy and safety of percutaneous balloon mitral valvuloplasty (PBMV) procedure in rheumatic heart disease patients with mitral valve (MV) stenosis and tricuspid valve regurgitation.
METHODSTwo hundred and twenty patients were enrolled in this study due to rheumatic heart disease with MS combined with TR. Mitral balloon catheter made in China was used to expand MV. The following parameters were measured before and after PBMV: MV area (MVA), TR area (TRA), atrial pressure and diameter, and pulmonary artery pressure (PAP). The patients were followed for 6 months to 9 years.
RESULTSAfter PBMV, the MVAs increased significantly (1.7 ± 0.3 cm 2 vs. 0.9 ± 0.3 cm 2 , P < 0.01); TRA significantly decreased (6.3 ± 1.7 cm 2 vs. 14.2 ± 6.5 cm 2 , P < 0.01), right atrial area (RAA) decreased significantly (21.5 ± 4.5 cm 2 vs. 25.4 ± 4.3 cm 2 , P < 0.05), TRA/RAA (%) decreased significantly (29.3 ± 3.2% vs. 44.2 ± 3.6%, P < 0.01). TR velocity (TRV) and TR continue time (TRT) as well as TRV × TRT decreased significantly (183.4 ± 9.4 cm/s vs. 254.5 ± 10.7 cm/s, P < 0.01; 185.7 ± 13.6 ms vs. 238.6 ± 11.3 ms, P < 0.01; 34.2 ± 5.6 cm vs. 60.7 ± 8.5 cm, P < 0.01, respectively). The postoperative left atrial diameter (LAD) significantly reduced (41.3 ± 6.2 mm vs. 49.8 ± 6.8 mm, P < 0.01) and the postoperative right atrial diameter (RAD) significantly reduced (28.7 ± 5.6 mm vs. 46.5 ± 6.3 mm, P < 0.01); the postoperative left atrium pressure significantly reduced (15.6 ± 6.1 mmHg vs. 26.5 ± 6.6 mmHg, P < 0.01), the postoperative right atrial pressure decreased significantly (13.2 ± 2.4 mmHg vs. 18.5 ± 4.3 mmHg, P < 0.01). The pulmonary arterial pressure decreased significantly after PBMV (48.2 ± 10.3 mmHg vs. 60.6 ± 15.5 mmHg, P < 0.01). The symptom of chest tightness and short of breath obviously alleviated. All cases followed-up for 6 months to 9 years (average 75 ± 32 months), 2 patients with severe regurgitation died (1 case of massive cerebral infarction, and 1 case of heart failure after 6 years and 8 years, respectively), 2 cases lost access. At the end of follow-up, MVA has been reduced compared with the postoperative (1.4 ± 0.4 cm 2 vs. 1.7 ± 0.3 cm 2 , P < 0.05); LAD slightly increased compared with the postoperative (45.2 ± 5.7 mm vs. 41.4 ± 6.3 mm, P < 0.05), RAD slightly also increased compared with the postoperative (36.1 ± 6.3 mm vs. 28.6 ± 5.5 mm, P < 0.05), but did not recover to the preoperative level. TRA slightly increased compared with the postoperative, but the difference was not statistically significant (P > 0.05). The PAP and left ventricular ejection fraction appeared no statistical difference compared with the postoperative (P > 0.05), the remaining patients without serious complications.
CONCLUSIONSPBMV is a safe and effective procedure for MS combined with TR in patients of rheumatic heart disease. It can alleviate the symptoms and reduce the size of TR. It can also improve the quality-of-life and prognosis. Its recent and mid-term efficacy is certain. While its long-term efficacy remains to be observed.

Objective:To analyze the correlation between 1H-MRS in hippocampus and peripheral blood cytokines and T lymphocyte subsets in patients with temporal lobe epilepsy, and to explore the relationship between immune dysfunction and the degree of neuronal injury. Methods:Fifty patients with temporal lobe epilepsy were selected from Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021.Clinical data of all patients were collected and they were divided into two groups according to MRI results of epileptic sequence: abnormal hippocampal MRI group ( n=20) and normal hippocampal MRI group ( n=30). Bilateral 1H-MRS scanning of hippocampal and detection of T lymphocyte subsets and cytokines in peripheral blood during interictal period were performed in both groups. The levels of hippocampal metabolites NAA, NAA/(Cr+ Cho), T lymphocyte subsets and cytokines in peripheral blood of the two groups were compared.At the same time, the levels of NAA and NAA/ (Cr+ Cho) in the hippocampus on the abnormal side and the normal side in the abnormal hippocampal MRI group were compared within the group. Finally, the correlation between the levels of metabolites NAA, NAA/ (Cr+ Cho) in the hippocampus on the abnormal side obtained by 1H-MRS scanning and T lymphocyte subsets and cytokines in the abnormal group of MRI was analyzed. The data were statistically analyzed by SPSS 26.0 software. Independent sample t-test or Mann-Whitney U test was used for comparison between the two groups. Paired sample t-test was used for intra group comparison of different sides. Spearman correlation analysis was used to analyze the correlation between each index. Results:The NAA and NAA/(Cr+ Cho) values of the abnormal MRI group(normal side NAA: (1.22±0.37), NAA/(Cr+ Cho): (0.56±0.15). abnormal side NAA: (1.02±0.34), NAA/(Cr+ Cho): (0.48±0.13)) were significantly lower than those of the normal MRI group (NAA: (1.51±0.36), NAA/(Cr+ Cho): (0.73±0.19))(NAA: t=2.705, 4.800, both P<0 05; NAA/(Cr+ Cho): t=3.394, 4.914, both P<0 05). The values of NAA and NAA/(Cr+ Cho) in the abnormal side in the MRI abnormal group were significantly lower than those in the normal side( t=6.467, P<0 05). The levels of IL-1β(11.19(3.56, 20.98)pg/ml), IL-5 (3.12(1.86, 6.41)pg/ml), TNF-α(2.55(1.19, 8.28)pg/ml), CD4+ T lymphocytes((43.13±6.82)%) and Th/Ts((1.96±0.66)) in the hippocampal MRI abnormal group were significantly higher than those in normal MRI group (IL-1β: 3.27(1.63, 6.17)pg/ml, IL-5: 1.15(0.96, 2.96)pg/ml, TNF-α: 1.34(1.02, 2.36)pg/ml, CD4+ T: (38.01±7.21)%, Th/Ts: (1.48±0.53))( Z=-3.041, -2.516, -2.496, all P<0.05; t=2.511, 2.810, both P<0 05). The level of CD8+ T ((23.48±5.33)%) in peripheral blood of abnormal MRI group was significantly lower than that of normal group CD8+ T((27.18±6.08)%)( t=2.210, P<0.05). In the abnormal MRI group, the levels of NAA and NAA/ (Cr+ Cho) in the abnormal hippocampus were negatively correlated with the levels of IL-1β, IL-5 and TNF- α ( r=-0.612--0.463, all P<0.05), and positively correlated with CD8+ T lymphocytes ( r=0.537, 0.478, P<0.05). Conclusion:There is neuronal damage and dysfunction in the abnormal hippocampal region of patients with temporal lobe epilepsy with abnormal hippocampal formation, and the degree of neuronal damage is highly correlated with CD8+ T lymphocytes, IL-5, IL-1β and TNF-α in peripheral blood. The imbalance of interictal lymphocyte subsets and chronic inflammatory response may play an important role in the pathogenesis of epilepsy and neuronal injury .

BACKGROUNDConsiderable evidence suggests that phosphatase of regenerating liver-3 (PRL-3) plays multiple roles in cancer metastasis; however, the molecular mechanisms remain largely unknown. The aim of this study was to identify proteins associated with PRL-3-promoted colon cancer metastasis, by comparative proteomic analysis.
METHODSProteomes of human colon cancer LoVo cells transfected with PRL-3 gene (LoVo-PRL-3) or empty vector PAcGFP-C3 (LoVo-control) were compared using 2D gel electrophoresis. Proteins that varied significantly in concentration were selected and identified using mass spectrometry. Expression of translationally controlled tumor protein (TCTP) mRNA and protein in LoVo-PRL-3 and LoVo-control cells was detected by real-time PCR and Western blotting. Small interfering RNA (siRNA) targeting TCTP was used for silencing TCTP expression in LoVo-PRL-3 cells. Functional significance of TCTP in PRL-3-promoted colon cancer cell proliferation, migration and invasion was investigated by Cell Counting Kit-8 assay and transwell chamber.
RESULTSSeventeen proteins displaying significant and reproducible differences between LoVo-PRL-3 and LoVo-control cells were identified. Ten proteins were upregulated and seven were downregulated in LoVo-PRL-3 cells when compared with LoVo-control cells. Eight identified proteins are associated with distinct steps of tumor metastasis: ubiquitin-like protein ISG15, interleukin-18, TCTP, serpin B5, annexin A3, macrophage-capping protein, ATP-dependent RNA helicase DDX3X, and cathepsin D. Real-time PCR and Western blotting results showed that both TCTP mRNA and protein were significantly increased in LoVo-PRL-3 cells compared to LoVo-control cells. Transfection with TCTP siRNA significantly reduced the expression of both mRNA and protein levels of TCTP in LoVo-PRL-3 cells. Knockdown of TCTP by siRNA inhibited PRL-3-promoted proliferation, migration and invasion of LoVo-PRL-3 cells.
CONCLUSIONOur results imply that TCTP might be a mediator of PRL-3-promoted proliferation, migration and invasion of human colon cancer cells.

OBJECTIVES(1) To evaluate the prevalence, phenotypes and suppressive function of CD4+CD25+ regulatory T cells (Tregs) among the in peripheral blood mononuclear cells (PBMCs) and tumor-infiltration lymphocytes (TILs) from hepatocellular carcinoma (HCC) patients and patients with chronic hepatitis B. (2) To investigate the correlation between the frequency of CD4+CD25+ Tregs and clinical characteristics of HCC patients.
METHODSPBMCs and TILs in 18 HCC patients, 10 chronic hepatitis B (CHB) patients and 15 healthy donors were evaluated for the phenotypes of CD4+CD25+ Tregs and the proportion of CD4+CD25+ Tregs as a percentage of the total CD4+ cells, by flow cytometric analysis with three or four color staining. The relationship between the frequency of CD4+CD25+ Tregs and tumor TNM stages was analyzed. The CD4+CD25+ Tregs and CD4+CD25- T cells were isolated from PBMC of HCC patients and donors. The suppressive function of CD4+CD25+ Tregs was analyzed.
RESULTSThe percentages of CD4+CD25+ Tregs of the HCC patients (6.38% +/- 6.30%) and CHB patients (4.29% +/- 1.82%) were significantly higher than those of the healthy donors (1.58% +/- 0.55%, P less than 0.01). Among the TILs, the percentage of CD4+CD25+ Tregs was higher (t = 4.39, P < 0.01). There were significant differences in the prevalence of CD4+CD25+ Tregs in early and advanced stage HCCs (stage II vs. III, P less than 0.05; stage II vs. IV P < 0.01). The proliferative capacity of CD4+CD25- T cells was inhibited by the presence of CD4+CD25+ T cells in a dose-dependent manner where the level of suppression was correlated to the ratio of the two-cell populations.
CONCLUSIONThese results suggest that the increase in frequency of CD4+CD25+ Tregs might play a role in the suppression of the immune response against HCC, which may contribute to the HCC cells that escaped from immunological surveillance.

Objective To compare the actions of Longbie Capsules and bone marrow mesenchymal stem cell (BMSC)transplantation in repairing the damaged cartilage of knee osteoarthritis(KOA)rats. Methods Thirty-six rats aged 4-6 weeks old were induced into KOA model(bilateral knees)by collagenase injection method. All of the modeled rats were randomly divided into model group(intragastric administration of normal saline), BMSC transplantation group(giving tail vein injection of 1 ×106 of BMSCs per time, 2 times every week), and Chinese medicine group (intragastric administration of Longbie Capsules of 7.5 g·kg-1·d-1),12 rats in each group. Six weeks later,the cartilage of rat bilateral knees was taken out. The pathological changes of cartilage were observed by hematoxylin-eosin(HE) staining method, and the protein and mRNA expression levels of Col2a1, X-linkedinhibitor of apoptosis protein (XIAP), HuR in rat knee cartilage were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR), respectively. Results The HE staining results showed that the cartilage tissue surface was rough with more cracks, and the cartilage cells gathered with the cytoplasm collapsed and arranging disorderly in the model group. The number of chondrocytes was increased and cell surface was flat,and the cracks of the cartilage were decreased with the chondrocytes arranging uniformly in Chinese medicine group and BMSC transplantation group compared with the model group. The results of immunohistochemistry and qPCR detection showed that in Chinese medicine dosage group and BMSC transplantation group, the protein and mRNA expression levels of Col2a1,XIAP and HuR were significantly higher than those in the model group (P<0.05 or P<0.0001), but there was no significant difference between the two medication groups(P>0.05). Conclusion Longbie Capsules and BMSC transplantation can promote the secretion of Col2a1 in the cartilage tissue of KOA rats,improve cartilage, and their mechanism may be related with up-regulating apoptosis-related proteins HuR and XIAP.
