Objective To study the clinical features of renal angiomyolipomas with tuberous sclerosis and to improve the recognization of this disease. Methods The diagnosis and treatment of 4 cases of tuberous sclerosis with bilateral and multiple renal angiomyolipomas were reviewed.The age range was 17 to 44 years,two of them were men.One patient presented with the classic triad:facial angiofibroma,seizures,and mental retardation.Facial angiofibroma occurred in three and seizures were found in two,three patients showed multiple extrarenal organ involvement including liver,spleen and bone.Brain CT revealed classical calcified cortical tuber and(or) subependymal nodule in three cases. Results The diagnosis of renal angiomyolipomas in three cases was affirmed on CT scan.However,the giant renal angiomyolipomas in one case can not be diagnosed from renal CT scan which did not demonstrate characteristic fatty tissue whereas the diagonsis was confirmed by ultrasound-guided right renal tumor biopsy and subsequent right nephrectomy for the large leisions.Regular monitoring of one patient was adopted for his mild symptomatic small renal leisions,the other two with hemorrhage in renal angiomyolipomas were reluctant to aggressive treatment and underwent conservative therapy.Follow-up ranged 6 to 36 months, none had recurrent symptoms and no significant growth of renal lesions was observed. Conclusions CT may not be pathognomonic for renal angiomyolipomas associated with tuberous sclerosis,needle biopsy may be needed to exclude renal carcinoma.The choice of treatment is based on tumor size distribution pattern,progression,and associated symptoms.

BACKGROUND:In recent years,with the improvement of living standards,non-alcoholic fatty liver disease has a gradually increasing trend.miRNA-122 is one of the most abundant microRNAs in the liver,which plays an important role in maintaining the environmental stability and differentiation of the liver.Exercise training is a non-drug treatment for non-alcoholic fatty liver disease,which may improve liver lipid metabolism by regulating the expression of miRNA-122. OBJECTIVE:To review the effects of miRNA-122 on the pathological factors related to non-alcoholic fatty liver disease as well as the effects of exercise on the expression of miRNA-122 and the occurrence and development of nonalcoholic fatty liver disease. METHODS:The first author searched the databases of CNKI,WanFang,VIP,PubMed,Geenmedical,EBSCO,Medline,Web of Science,and Elsevier using"non-alcoholic fatty liver disease,microRNA,microRNA-122,lipid metabolism,inflammatory response,insulin resistance,exercise,physical exercise,exercise training"as the English and Chinese search terms for all relevant literature published before June 5,2022.All included documents were screened,summarized,and analyzed.Finally,68 documents were included for review. RESULTS AND CONCLUSION:Compared with the healthy control group,the expression of circulating miRNA-122 is increased in patients with non-alcoholic fatty liver disease.The level of miRNA-122 may show different expression levels at different stages of non-alcoholic fatty liver disease.miRNA-122 can regulate the expression of downstream-related proteins,influence lipid metabolism,inflammatory response,insulin resistance and other pathogenic factors in non-alcoholic fatty liver disease by targeting base complementary pairing sites on mRNA or directly acting as physiological ligands of some RNA receptors.Different exercise modes can improve non-alcoholic fatty liver disease.Therefore,patients with non-alcoholic fatty liver disease need to complete at least 120 minutes of moderate-intensity exercise every week to have a positive effect.For patients who can tolerate various exercises,priority should be given to the combination of aerobic and resistance exercises 4-5 times a week.The exercise intensity should be 50%-70%of the maximum heart rate and the exercise should last for>3 months.For patients with poor tolerance,resistance exercise may be more feasible than aerobic exercise.In addition,patients with non-alcoholic fatty liver disease can also choose proper exercise modes according to their own disease conditions(such as liver enzymes and lipid levels).Exercise can be used as a feasible strategy to prevent non-alcoholic fatty liver disease,reduce liver steatosis,and alleviate liver inflammatory response and insulin resistance.Exercise training can regulate the expression of miRNA-122,but in patients with non-alcoholic fatty liver disease,the effect of exercise on miRNA-122 and its related signal pathways remains to be studied.

Objective:To explore the clinical effect of ALTF transfer with cross-limb bridged "Y" shape vascular anastomosis in repair of complex soft tissue defects in calf.Methods:From August 2010 to September 2020, 33 patients(23 males and 10 females) with complex traumatic soft tissue defects in calf were treated. Preoperative angiography and intraoperative exploration confirmed that there was only 1 main vessel remained in the affected calf or the wound surface and the vessel could not be anastomosed with the vascular pedicle of the ALTF. The size of flap were 16 cm × 8 cm to 25 cm × 18 cm. Two patients received bilobed ALTFs. A "Y" shape anastomosis between the artery of ALTF vascular pedicle and the posterior tibial artery of the contralateral lower limbs was made in all 33 patients to establish the blood supply to the transferred free ALTF. The "Y" shape cross-limb bridged blood vessels at the proximal end of the vascular pedicle artery of the flap were embedded at both ends of the cut-off superior ankle posterior tibial artery of the contralateral lower limb. The vein of the flap was anastomosed with the saphenous vein that associates with the posterior tibial artery. The surface of the suspended blood vessel "bridge" was wrapped with a free skin craft, and the lower limbs were fixed in a straight and parallel position with an external fixation frame. The perfused area of the flap was directly sutured or covered with a free skin craft. The vascular bridge was kept for 3 to 6 weeks before being separated. Outpatient follow-up after discharge.Results:All the patients were entered the postoperative follow-up was 13 months to 7 years, in an average of 25 months. Among the 33 flaps, 31 survived completely, except 1 had necrosis and the other 1 had partial necrosis at the distal end of the flap. The flaps received good blood supply, hence with soft texture and satisfactory appearance. Doppler or DSA was performed after the surgery on the posterior tibial artery of the healthy limb, and the vascular pulsation and patency were found normal. Donor sites for the free skin graft healed well.Conclusion:The ALTF transfer with cross-limb bridged "Y" vascular anastomosis is one of the effective techniques and it was employed in the repair of complex defects of calf soft tissue. It solved the tissue that there was only 1 main vessel or even without a suitable vessel could be anastomosed with the pedicle of the flap.

[Objective] To evaluate the value of X-ray combined with MRI in the diagnosis of rotator cuff injury. [Methods] A retrospective study was conducted on the patients who underwent X-ray and MRI examinations at the First Affiliated Hospital of Air Force Medical University from January 2021 to March 2022. A total of 158 patients were recruited, among whom 146 had rotator cuff injury, 10 had rheumatoid arthritis, and 2 had shoulder joint space occupation. We compared the specificity, sensitivity, consistency, detection rate, missed diagnosis rate and misdiagnosis rate of various examinations, and compared the X-ray and MRI examination results. [Results] The sensitivity and specificity of X-ray for rotator cuff injury were 65.8% and 41.7%, those of MRI for rotator cuff injury were 78.1% and 66.7%, and those of the combined diagnosis were 93.8% and 83.3%, respectively. The Kappa value of the combined diagnosis of rotator cuff injury and surgical results was higher than that of X-ray and MRI diagnosis (P<0.05). The detection rate and missed diagnosis rate of the three groups differed significantly (χ²=6.095, 13.113, P<0.05). The detection rate of rotator cuff injury by the combined diagnosis was higher than that of X-ray and MRI diagnosis, and the missed diagnosis rate was lower than that of the latter (P>0.05). [Conclusion] The detection rate of rotator cuff injury of shoulder joint by the combined examination is higher than that of X-ray and MRI, and the rate of missed diagnosis and misdiagnosis is lower. The combined examination can provide detailed evaluation for preoperative diagnosis.

Objective:To investigate the clinical effect of free flap transfer with anastomosis of anterior interosseous artery and accompanying veins as the recipient vessels in reconstruction of forearm defects.Methods:A retrospective study was conducted on 5 patients who received free flaps transfers with anastomoses of anterior interosseous artery and accompanying veins in reconstruction of forearm defects with exposed bone and tendon in the Department of Orthopaedics of the First Affiliated Hospital of Anhui Medical University between July 2022 and November 2023. All patients were males, aged 31 to 54 years old with an average age of 41.8 years old. Two patients had defects of dorsal ulnar forearm, 2 of distal forearm and 1 of radial palmar forearm. The defected areas after debridement sized 11.0 cm×4.5 cm-20.0 cm×6.0 cm. Free anterolateral thigh perforator flaps (ALTPF), sized 13.0 cm×6.0 cm-22.0 cm×7.0 cm, were used in 4 patients to reconstruct the forearm defects. A free superficial circumflex iliac artery perforator flap was used in 1 patient with the flap sized at 12.0 cm×5.5 cm. All donor sites were directly sutured. Scheduled postoperative follow up was carried out to evaluate the blood supply to the flaps, texture, appearance, fracture healing and the function of the affected limb, as well as the flap sensation according to the criteria for sensory function of British Medical Research Council (BMRC).Results:All 5 patients had received 4 to 16 (mean 8.8) months of follow-up. All flaps survived completely without necrosis or infection. All flaps were good in colour and texture. The blood supply to hands was good, without a symptoms of coldness and fear of cold of hand. At the final follow-up review, sensation of flaps was assessed according to the criteria for sensory function of BMRC and the sensation of the flaps had recovered to S 2~S 3+. The appearance of flaps was good. Conclusion:Free flap with the anterior interosseous artery and accompanying veins as the recipient vessels in the treatment of forearm defects can achieve satisfactory clinical effect, however, further clinical studies are required.

This paper discussed the nature of ulcerative colitis， that is deficiency of the root and excess of the branch， from the theory of sweat pore， and to explore the theoretical basis and experience of treating this disease with retention enema of traditional Chinese medicine （TCM）. The main location of this disease is in the intestine. As a part of sweat pore， the intestinal sweat pore serves as the gateway for the ascending， descending， exiting and entering of qi movement in the zang fu （脏腑） organs， meridians and collaterals， as well as the channel for the transportation of qi， blood and body fluids. The constraint and closure of the intestinal sweat pore are the main pathological basis of ulcerative colitis. According to the manifestations of colonoscopy， and the different etiological factors and pathogenesis that lead to the constraint and closure of sweat pore， there should be different treatment focuses such as expelling wind to open sweat pore， clearing fire to open sweat pore， promoting blood circulation to open sweat pore， for which wind-dispersing herbs， heat-clearing herbs， and blood-activating herbs are used accordingly. The method of retention enema can directly induce Chinese medicinal herbs to the affected part， so as to diffuse and unblock the sweat pore， regulate qi and blood， and thus restore the normal function of the intestinal sweat pore.
