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 analyze the independent diagnostic indicators and their diagnostic values for pulmonary tuberculosis complicated with pulmonary embolism.Methods:A total of 34 cases of pulmonary tuberculosis complicated with pulmonary embolism treated in Huzhou Central Hospital from March 2014 to September 2021 were enrolled. And 136 patients with simple pulmonary tuberculosis who were hospitalized during the same period were collected with a ratio of 1∶4 according to the principle of age and gender matching. The general conditions, clinical symptoms, comorbidities and laboratory indicators of the patients were retrospectively analyzed. The univariate analysis was performed using independent samples t test, Mann-Whitney U test and chi-square test. Binary logistic regression was used to analyze the related diagnostic factors for pulmonary embolism in pulmonary tuberculosis patients, and the combined factors were constructed by transforming the model equation, and the receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value and evaluate its diagnostic value. Results:The univariate analysis showed that patients with pulmonary tuberculosis complicated with pulmonary embolism had higher ratio of chest tightness (67.6%(23/34) vs 22.1%(30/136)), syncope (23.5%(8/34) vs 0.7%(1/136)), fever (55.9%(19/34) vs 36.0%(49/136)), hemostatic drug use (100.0%(34/34) vs 13.2%(18/136)), history of venous thrombosis (8.8%(3/34) vs 0.7%(1/136)), atrial fibrillation (11.8%(4/34) vs 2.2%(3/136)) and D-dimer levels (4.090 0(1.035 0, 10.790 0) mg/L vs 0.850 0(0.432 5, 2.145 0) mg/L) than those of simple pulmonary tuberculosis patients, and the differences were all statistically significant ( χ2=26.35, 28.19, 4.47, 96.44, 7.75, 6.30 and Z=-4.65, respectively; all P<0.050). The arterial partial pressure of oxygen (PaO 2)(61.90(52.95, 73.00) mmHg vs 82.00 (75.00, 87.00) mmHg, 1 mmHg=0.133 kPa) and albumin ((28.83±4.98) g/L vs (32.76±5.65) g/L) of patients with pulmonary tuberculosis complicated with pulmonary embolism were lower than those of simple pulmonary tuberculosis patients, and the differences were both statistically significant ( Z=-5.21 and t=3.71, respectively, both P<0.001). Binary regression analysis showed that chest tightness (odds ratio ( OR)=3.494, 95%confidence interval ( CI) 1.208 to 10.100, P=0.021), D-dimer ( OR=1.285, 95% CI 1.079 to 1.530, P=0.005) and PaO 2( OR=0.931, 95% CI 0.895 to 0.970, P=0.001) were the independent diagnostic indicators for pulmonary embolism in pulmonary tuberculosis patients. The areas under the ROC curve of chest tightness, D-dimer, PaO 2, and the combination of the three indicators (the combination factor) were 0.728, 0.758, 0.834, and 0.890, respectively. The optimal cut-off value of the combination factor was -3.1, with the sensitivity of 0.824 and the specificity of 0.824. Conclusions:Chest tightness, increased D-dimer and decreased PaO 2 are independent diagnostic indicators for pulmonary embolism in pulmonary tuberculosis patients. It is recommended to perform pulmonary artery computed tomography angiography promptly when the combination factor is higher than -3.1 to determine whether the patient is complicated by pulmonary embolism.

Objective@#To investigate the effect of histone deacetylase inhibitor apicidin on the glioblastoma U87 cells and its regulation of OCT-4 gene expression.@*Methods@#Glioblastoma U87 cells were treated with different concentrations of apicidin, and dimethyl sulfoxide instead of apicidin was negative control. Methyl thiazolyl tetrazolium (MTT) assay was used to detect the proliferative ability of U87 cells treated by apicidin. The cell apoptosis was observed under the fluorescence microscope, and the cell cycle was detected by using flow cytometry. Reverse transcription-polymerase chain reaction and Western blot was used to detect the expression of mRNA and protein of U87 cells, respectively relative to the expression of GAPDH.@*Results@#MTT assay results showed that apicidin inhibited U87 cells proliferation in a dose-dependent and time-dependent manner, and half of the inhibitory concentration of cell proliferation at 48 h was (1.74±0.13) μmol/L. The cell proportion of U87 cells in S-phase of the negative control, 0.2, 0.5, and 1.0 μmol/L apicidin was (32.68±0.49)%, (33.73±0.76)%, (42.92±0.56)%, and (56.95±0.53)%, respectively after 48 h apicidin administration (P < 0.05), while the proportion of G1 and G2 phase cells was decreased. The karyopyknosis and other apoptotic changes were detected in U87 cells after 48 h treatment of 1.0 μmol/L apicidin under the confocal fluorescence microscope. Western blot and RT-PCR showed that the mRNA and protein relative levels of U87 cells OCT-4 were reduced after 1.0 μmol/L apicidin treatment for 48 h compared with the negative control group (mRNA: 72.44±0.00 vs. 56.66±0.23; protein: 86.59±0.19 vs. 56.04±0.15, both P < 0.01).@*Conclusions@#Apicidin can inhibit the growth of glioblastoma U87 cells, induce cell cycle arrest and apoptosis. Its mechanism may be related to the expression of OCT-4 inhibited by apicidin.

OBJECTIVE: To investigate the improvement effects of water extract of Astragalus membranaceus on chronic renal failure (CRF) model rats and its effects on MAPK signaling pathway, and to investigate possible mechanism. METHODS: Male SD rats were randomly divided into control group (10 rats) and model group (50 rats). CRF model was established by intragastric administration of 25% Adenine suspension 200 mg/kg (once a day, for consecutive 28 d). After modeling, modeling group was randomly divided into model group, benazepril group (positive control, 2 mg/kg), A. membranaceus water extract low-dose, medium-dose and high-dose groups (1.5, 3, 6 g/kg,by crude drug), with 10 rats in each group. Control group and model group were given constant volume of normal saline intragastrically, and administration groups were given relevant medicine intragastrically, once a day, for consecutive 28 d. Twelve hours after last medication, the contents of serum renal function indexes (serum creatinine, urea nitrogen, uric acid) were determined by colorimetry. ELISA method was used to detect the levels of serum inflammatory factors (IL-1β, IL-6 and TNF-α). The activity or content of oxidative stress related indexes (SOD, CAT and MDA)in renal tissue of rats were determined by hydroxylamine method, visible spectrophotometry method and thiobarbituric acid method. The mRNA expression of apoptosis-related factors (Bax, Bcl-2, Caspase-3) in renal tissue, MAPK signaling pathway-related regulatory protein p38 MAPK, phosphorylated p38 MAPK(p-p38 MAPK), ERK1/2, phosphorylated ERK1/2 (p-ERK1/2), JNK and phosphorylated JNK (p-JNK) were determined by real- time PCR and Western blotting assay. RESULTS: Compared with control group, the contents of renal function indexes and the levels of inflammatory factors in serum, MDA content, mRNA expression ratio of Bax and Bcl-2 (Bax/Bcl-2), mRNA related expression of Caspase-3, related expression of phosphorylation product of MAPK signaling pathway-related regulatory proteins (p-p38 MAPK, p-JNK, p-ERK1/2) in renal tissue were increased significantly in model group, while the activities of SOD and CAT were decreased significantly in renal tissue (P<0.01). Compared with model group, the contents of renal function indexes and the levels of inflammatory factors in serum, Bax/Bcl-2, related expression of phosphorylation product of MAPK signaling pathway-related regulatory proteins in renal tissue were decreased significantly in administration groups as well as MDA content and mRNA related expression of Caspase-3 were decreased significantly in benazepril group and A. membranaceus water extract medium-dose and high-dose groups; the activities of SOD and CAT in renal tissue were increased significantly in benazepril group and A. membranaceus water extract medium-dose and high-dose groups (P<0.05 or P<0.01). MDA content and Bax/Bcl-2 of benazepril group were significantly lower than those of A. membranaceus water extract high-dose group (P<0.05). CONCLUSIONS: A. membranaceus water extract has a certain improvement effect on CRF model rats, and inhibit its inflammatory reaction, oxidant stress and cell apoptosis, the mechanism of which may be associated with inhibiting the expression of MAPK signaling pathway-related regulatory proteins.

Objective To explore effects of different urostomy education paths in patients undergoing cystectomy with creation of a urostomy.Methods 42 cases of patients after radical cystectomy with creation of a urostomy were randomly divided into the control group and the observation group. The control group received the original version of urostomy education path, while observation group received modified version of urostomy education path. Knowledge of urostomy, stoma bag replacing skills, and length of hospital stay were compared between the two groups. Results Patients in the observation group who received modified version of urostomy education path showed better knowledge of urostomy and skills of replaceing stomy bag, as well as shorter hospital stay (P<0.05).Conclusions Our modified version of urostomy education path results in improved self-care ability among patients and their family members. It suggests the urostomy education needs constant innovation and enhancement on the basis of practice.
