OBJECTIVE:To provide reference for clinical rational use and purchase of TCM decoction pieces for rheumatism. METHODS:Using Excel software,the application of TCM decoction pieces for rheumatism in our hospital during 2010-2014 was analyzed statistically in respects of drug type,consumption quantity and consumption sum,etc. RESULTS:The consumption quan-tity of TCM decoction pieces for rheumatism increased from 46 026 kg to 79 139 kg in our hospital during 2010-2014,and annual growth rate was 14.68%;consumption sum increased from 3 851 300 yuan to 6 403 800 yuan,with annual growth rate was 15.46%;consumption quantity ratio was 2.48%-2.85%. Among antirheumatic drug subtype,the quantity of drugs for antirheumatic and dissipating cold was the largest (accounting for 51.43%-58.42%),followed by drugs for antirheumatic and strengthening the bones and muscles(accounting for 23.05%-28.42%)and drugs for antirheumatic and clearing heat(accounting for 18.53%-21.08%). Top 3 TCM decoction pieces for rheumatism in the list of annual quantity were Viscum coloratum,Cynanchum paniculatum and Clematis chinensis/Chaenomeles sinensis during 2011-2014. Top 3 TCM decoction pieces for rheumatism in the list of consumption sum were Zoacys dhumnades,C. paniculatum and V. coloratum during 2011-2014. CONCLUSIONS:Both consumption quantity and consumption sum of TCM decoction pieces for rheumatism have increased year by year in our hospital,but the ratio of total quantity to total amount and medication structure keep stable,and TCM for expelling wind-damp and dispelling cold is the greatest in consumption quantity which is in line with clinical drug use characteristics. Purchasing staff can purchase drugs predictably ac-cording to the results.

Objective To know the utilization and development trend of TCM decoction pieces for clearing damp and promoting diuresis in our hospital;To provide references for rational medicine use and purchase in clinic.

Objective:To investigate the anatomy of rectus femoris muscle flap and the anterolateral thigh muscle flap and their clinical application in reconstruction of large soft tissue defects after the removal of oral malignant tumour.Methods:From December 2006 to June 2009, 8 specimens of Chinese adult cadavers fixed in 10% formaldehyde were dissected to perform anatomy of anterolateral thigh region at the School of Basic Medical Sciences, Kunming Medical University. Anatomical images were analysed using Image-Pro Plus 6.0. Then, a retrospective study was performed on 19 patients who had postoperative defects after oral malignant tumour surgery and the defects were reconstructed with the rectus femoris muscle flap and the anterolateral thigh muscle flap from March 2020 to July 2022 at the Department of Oral and Maxillofacial Surgery, Affiliated Stomatology Hospital, Kunming Medical University. The postoperative defects of the 19 patients ranged from 3.0 cm×6.0 cm to 5.0 cm×10.0 cm. Ten rectus femoris muscle flaps, 8 anterolateral thigh muscle flaps and 1 combined rectus femoris muscle flap and anterolateral thigh muscle flap were used. The muscular flaps sized from 4.0 cm × 8.0 cm to 6.0 cm × 11.0 cm. Regular postoperative outpatient follow-ups were conducted.Results:The lengths of vessels of the harvested rectus femoris muscle flap and anterolateral thigh muscle flap were 63.4 mm± 12.9 mm and 112.5 mm± 19.6 mm, respectively. The starting outer diameters of the lateral circumflex thigh artery, the oblique branch of the lateral circumflex thigh artery and the descending branch of the lateral circumflex thigh artery were 2.92 mm±0.72 mm, 1.88 mm±0.23 mm and 2.29 mm±0.43 mm, respectively. Postoperative follow-up lasted for 7 to 32 months, with 17.5 months in average. Seventeen flaps were completely survived and the rectus femoris muscle flap was completely mucosalised 5 weeks after surgery. However, 2 rectus femoris muscle flaps had necrosis of which one was changed to a tongue flap reconstruction and the other encountered flap necrosis during postoperative radiotherapy and healed after debridement and dressing changes. There was no postoperative complication in the donor sites. Other than the 2 patients, all other 17 patients had satisfactory clinical outcomes.Conclusion:Both of the starting outer diameters and length of vessels of the femoris muscle flap and the anterolateral thigh muscle flap meet the requirements for reconstruction of maxillofacial defects, and both muscular flaps are simple to prepare, in good reconstructive results with few complication, as well as an excellent outcome. They are feasible approaches for reconstruction of large soft tissue defects left after the removal of an oral malignant tumour.

Objective To investigate the regulatory effect of miR-132-3p on calmodulin-binding transcription activator 1(CAMTA1)and Schwann cell activity in rats with facial nerve injury(FNI)treated with I-125 seeds.Methods Rat Schwann cells were irradiated with I-125 seeds and transfected with miR-132-3p mimic,miR-132-3p inhibitor or sh-CAMTA1.The expressions of S100B and β-tubulin Ⅲ in the cells were detected with immunofluorescence assay,and the expressions of miR-132-3p and CAMTA1 protein were determined using RT-qPCR and Western blotting,respectively.EdU staining and Transwell assay were used to evaluate the changes in cell proliferation and migration ability.In a rat model of FNI,I-125 seeds were implanted into the facial tissues near the facial nerve 2 weeks before modeling,and miR-132-3p mimic was injected subcutaneously in the face after modeling.The pathologies of the facial nerve was assessed by HE,LFB and immunofluorescence staining.The targeting relationship between miR-132-3p and CAMTA1 was verified using StarBase v2.0 database and dual-luciferase reporter assay.Results Rat Schwann cells showed high expressions of S100B and β-tubulin Ⅲ.I-125 seeds radiation significantly decreased miR-132-3p expression and repressed proliferation and migration of the cells(P<0.001).Overexpression of miR-132-3p or CAMTA1 knockdown obviously enhanced proliferation and migration of the Schwann cells,while miR-132-3p knockdown produced the opposite effect.MiR-132-3p negatively regulated CAMTA1 expression.In the rat models of FNI,miR-132-3p injection significantly inhibited CAMTA1 expression and attenuated I-125 seeds-induced exacerbation of FNI.Conclusion Overexpression of miR-132-3p suppresses CAMTA1 expression and promotes Schwann cell proliferation and migration to alleviate I-125 seeds-induced exacerbation of FNI in rats.

2 patients with lateral orbital malignant tumors were treated by tumor resection and autologous pedicled coronoid-temporalis muscle flap repair of the orbital wall defect.The flaps survived well without obvious facial collapse deformity and with good orbital wall func-tion and aesthetic effect,the mouth open pattern,the intra-oral occlusion and the masticatory function were satisfactory.

Objective:To investigate the clinical outcomes of sublingual gland flap in the repair of postoperative jaw defects because of chronic phosphorous osteomyelitis(PNJ)and medication-related osteonecrosis of the jaw(MRONT).Methods:3 patients with PNJ and 2 with MRONJ were treated by sublingual gland flap in the repair of the postoperative jaw defet.The treatment effects were evalua-ted by clinical obseration.Results:In the 5 patients the wound healed well within 2 weeks postoperatively,with no infection and with normal sublingual gland function after surgery.Conclusion:The use of sublingual gland flap is an effective and feasible method for re-pairing local defects in the mandibles after surgery for chronic PNJ and MRONJ.

Objective:To investigate mevalonic acid(MEV)on reversing the antitumor effects of fluvastatin sodium(FS)on tongue squamous cell carcinoma(TSCC)cells.Methods:TSCC HSC-4 cells were treated with different concentrations of FS and MEV re-spectively or in combination.Cell counting kit-8,flow cytometry,wound healing,immunofluorescence and western blotting assays were conducted to examine cell proliferation,apoptosis and migration capacities,as well as the expression levels of Ras homolog family member A(RHOA),tissue factor(TF)and B-cell lymphoma-2-associated X(BAX)proteins,respectively.Results:FS inhibited HSC-4 cell proliferation and migration,decreased the expression of RHOA and TF,and increased BAX expression.MEV reversed the above antitumor effects of FS and promoted intracellular RHOA and TF expression.Conclusion:MEV reverses the antitumor effects of FS on HSC-4 cells in vitro.
