OBJECTIVE:To observe the clinical efficacy of sitagliptin combined with benazepril in the treatment of diabetic nephropathy(DN). METHODS:Sixty DN patients admitted to our hospital during Sept. 2014-Jun. 2015 were divided into sitagliptin group,benazepril group,drug combination group according to random number table,with 20 cases in each group. Based on routine treatment,sitagliptin group was given sitagliptin 100 mg orally,qd;benazepril group was given Benazepril 10 mg orally,qd;drug combination group was given sitagliptin 100 mg+benazepril 10 mg orally,qd. The drug dosage would be doubled if the blood pressure of patients in 3 groups had not yet reached the standard. Treatment course of 3 groups lasted for 12 weeks. The levels of 24 h urine protein,IL-6 and Cys-C were measured in 3 groups before and after treatment. Clinical efficacies and the occurrence of ADR were observed. RESULTS:Total response rate of drug combination group(90.00%)was significantly higher than those of sitagliptin group (65.00%)and benazepril group(70.00%);there was statistically significance(P<0.05). After treatment,the levels of 24 h urine protein,IL-6 and Cys-C in 3 groups were significantly lowered,compared to before treatment;those of drug combination group was significantly lower than those of other 2 groups;there was statistically significance(P<0.05). There was no statistical significance in above indexes between sitagliptin group and benazepril group(P>0.05). No obvious ADR was found in 3 groups during treatment. CONCLUSIONS:Both sitagliptin and benazepril can decrease the levels of 24 h urine protein,IL-6 and Cys-C,while drug combination shows better effect and clinical response rate,and does not influence the safety of drug use.

Objective:To investigate the long-term effect of the implantation of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) for type 1 diabetes mellitus.Methods:Fifteen patients with type 1 diabetes mellitus were treated with HUC-MSCs from September 2009 to December 2011 at Department of Endocrinology and Metabolism, the Second People′s Hospital. Patients were followed-up for 10 years and the parameters were collected including fasting blood glucose, HbA 1C, mean amplitude of glycemic excursions (MAGE), fasting C-peptide, daily insulin doses and glutamic acid decarboxylase antibody (GADA). Results:Among 15 patients, 1 patient (6.67%) was found with breast cancer. All patients with type 1 diabetes mellitus decreased daily insulin doses due to frequent hypoglycemia one week later. Six months later, 4 patients (26.67%) stopped insulin injection. While among the 4 patients, 1 patient (6.67%) had not yet used insulin until today and GADA was negative, the other 3 patients (20.00%) restarted insulin within 3-5 years after implantation with significantly less daily insulin doses [(18.00±1.00)U vs (29.00±1.73)U, P<0.01]. The remaining 11 patients (73.33%) with type 1 diabetes mellitus who did not stop insulin also had significantly lower daily insulin doses [(18.09±0.83)U vs (29.64±0.89)U, P<0.01]. The level of MAGE was signicantly decreased compared to those of pre-implantation [(6.14±0.25)mmol/L vs (9.72±0.32)mmol/L, P <0.01], while fasting C-peptide level was significantly improved[(0.91±0.03)nmol/L vs (0.11±0.01)nmol/L, P <0.01]. There were no significant differences in fasting blood glucose and HbA 1C before and after implantation. Conclusions:The implantation of HUC-MSCs for the treatment of type 1 diabetes mellitus can restore the function of islet β cells, decrease daily insulin doses and reduce blood glucose fluctuations in the long term. Although precise mechanisms are unknown, this therapy is expected to be an effective strategy for treatment of type 1 diabetes mellitus.

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 study the protective effect of Mongolian medicine Bateri-7 on radiation-induced intestinal injury in mice.Methods:C57BL/6J male mice were randomly divided into control group, irradiation group and irradiation plus drug administration group, with 10 or 15 mice in each group. For irradiation group, the mice were given a single dose of 12 Gy 60Co γ-rays with total body irradiation. For drug treatment, the mice were gavaged with Bateri-7 (530 mg/kg) 7 d before irradiation until 3 d after IR. At 6 h and 24 h after irradiation, the Tunel positive cells in intestine were detected immunohistochemically. At 3.5 d after irradiation, the structure of intestinal villi was observed by HE staining, and the BrdU and Ki67 positive cells were detected immunohistochemically. The expression levels of IL-6, TNF-α and Cxcl-5 were detected by qPCR. The FITC-dextran in peripheral blood was also determined. Results:The survival of irradiated mice was significantly increased by Bateri-7 ( χ2= 5.84, P < 0.05), but there was no significant difference in weight between two groups ( P > 0.05). The villi length of small intestine in the irradiation plus drug group was significantly longer than that in the irradiation group ( t = 20.24, P < 0.05), and there was no significant difference in the depth of intestinal crypt between two groups ( P > 0.05). At 6 and 24 h after irradiation, the number of Tunel positive cells in intestinal crypts in the irradiation plus drug group was significantly reduced in comparison with the irradiation group ( t = 3.52, 2.90, P < 0.05). At 3.5 d after irradiation, the level of FITC-dextran in serum and the expressions of IL-6, TNF-α and Cxcl-5 in small intestine of mice in the irradiation plus drug group were significantly lower than those in the irradiation group, respectively( t = 6.92, 7.01, 7.18, 13.16, P < 0.05). The number of BrdU and Ki67 positive cells in the crypt of mice in the irradiation plus drug group was higher than that of the irradiation group ( t = 3.91, 2.57, P < 0.05). Conclusions:Mongolian medicine Bateri-7 can effectively alleviate irradiation-induced intestinal injury of mice, which may have a good preventive and therapeutic effect on radiation enteritis.

ObjectiveTo evaluate the efficacy and safety of Rongjin Tongbi decoction on sciatica caused by lumbar intervertebral disc herniation with liver and kidney deficiency type based on a randomized controlled study. MethodFrom January 2019 to July 2022， 90 patients in the department of Traditional Chinese medicine（TCM） of Beijing Jishuitan Hospital who met the inclusion criteria were selected and divided into two groups according to the random number table， with 45 patients in each group. During the study， 19 cases dropped out， with 41 cases included in the final observation group and 30 cases in the control group. The observation group was given Rongjin Tongbi decoction orally， and the control group was given Loxoprofen Sodium Tablets orally for 28 days. The differences in the visual analog scale （VAS） scores， the Japanese Orthopaedic Association （JOA） scores， activities of daily living （ADL） assessments， TCM clinical symptoms， subjective symptoms， and clinical signs scores between two groups before and after treatment were observed. Liver and kidney functions and gastrointestinal adverse reactions were detected for safety evaluation. ResultBefore treatment， there was no statistically significant difference in scores between the observation group and the control group. After treatment， the absolute values of the differences in VAS and ADL scores in the observation group were higher than those in the control group （P<0.05）. There was no statistically significant difference in the absolute value of the difference in JOA scores between two groups. The absolute value of the difference in TCM clinical symptom scores in the observation group was higher than that in the control group （P<0.01）. There was no statistically significant difference in the absolute values of the differences in subjective symptom and clinical sign scores between two groups. The levels of liver and kidney function indicators in both groups before and after the experiment were normal， and there was no significant difference in gastrointestinal reactions. ConclusionRongjin Tongbi decoction can significantly improve the symptoms of sciatica patients caused by lumbar intervertebral disc herniation with liver and kidney deficiency type.

We report a case of chromoblastomycosis caused by , which was successfully treated by long-pulsed 1064 nm Nd: YAG laser combined with terbinafine. A 60-year-old man was admitted for the presence of a 30 mm×40 mm erythematous plaque on the dorsum of his right hand for about 10 months without any subjective symptoms. Both microscopic examination and tissue biopsy of the lesion showed characteristic sclerotic bodies of chromoblastomycosis. Lesion tissue culture on SDA at 26 ℃ for 2 weeks resulted in a black colony, and slide culture identified the isolate as Fonsecaea species. ITS sequence analysis of the isolate showed a 99% homology with strain KX078407. The susceptibility of the isolate to 9 antifungal agents was determined using the microdilution method according to the guidelines of CLSI M38-A2 protocol, and terbinafine showed the lowest MIC (0.125 μg/ml). We subsequently established a Wistar rat model of chromoblastomycosis using the clinical isolate and treated the rats with long-pulsed 1064 nm Nd: YAG laser (pulse width of 3.0 ms, fluence of 24 J/cm, spot size of 3 mm, frequency of 4 Hz, repeated 3 times at an interval of 30 s) twice a week for a total of 8 sessions. Although the laser treatment alone was not able to eliminate the fungi, histopathological examination showed the aggregation of numerous lymphocytes in the local affected tissue, indicating an immune response that consequently facilitate the regression of the lesion. The patient was successfully treated by long-pulsed 1064 nm Nd: YAG laser once a week combined with terbinafine (0.25 /bid) for 8 weeks, and follow-up for 20 months did not reveal any signs of recurrence.
