Objective:To summarise the clinical experience in replantation of the severed auricle distal to helix with microsurgical technique.Methods:From December 2018 to October 2021, a total of 5 patients with severed auricle injury were treated in the Department of Hand and Foot Surgery of The Affiliated Hospital of Qingdao University. They were 4 males and 1 female with 23-62 years old. After complete debridement of the auricular pinna, the retrograde replantation method was used. For arteries: a dorsal vein of the foot was used to bridge the posterior auricular artery. For veins: 2 patients had the veins directly anastomosed, 2 had the arteriovenous bridging to the posterior ear vein with dorsal foot veins, and the veins in 1 case were not anastomosed. Among the patients, 2 developed venous occlusions after severed auricle, and were treated with bloodletting through small incision at the skin margin. Two patients who received the arteriovenous of the severed auriclse achieved good blood supply. All the patients underwent treatments including anti-freezing, anti-spasm and anti-infection after the emergency surgery. The follow-ups were conducted regularly by telephone and by display photos via WeChat after surgery.Results:All 5 severed auricles were successfully replanted and survived. Postoperative follow-up ranged from 3 months to 2 years, with an average of 10 months. In the 2 cases with venous crisis, the auricles had mild atrophy. All auricles had no obvious pigmentation, and had the sensation recovery back to normal in 1 year after surgery.Conclusion:The pre-judgment of blood vessel quality and high-quality microsurgery skills are the necessary pre-conditions for auricle replantation. For replantation of severed auricle, it is the key to prevent vascular crisis by having the injured blood vessels thoroughly removed.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

Danshen,an efficacious agent for cardiovascular diseases,has been found to play an essential role in kidney injury.In the present study,the effect of Danshen on cisplatin-induced renal dysfunction was investigated in a mouse model.Danshen was administered to mice at a dose of 3 g/kg 4 days before and 3 days after cisplatin treatment.A single intraperitoneal injection of 20 mg/kg cisplatin was used to induce nephrotoxicity.The mice were sacrificed 72 h after cisplatin intoxication.Biochemical parameters including serum creatinine and blood urea nitrogen were analyzed.Histopathological changes of kidney tissues were detected using HE staining.Antioxidant enzymes (GSH-Px and SOD) and peroxidative product (MDA) were detected.Protein expressions of Nrf2 and its target genes including HO-1 and NQO1 were measured by Western blotting.The results showed that pretreatment with Danshen significantly reduced serum creatinine and blood urea nitrogen in the cisplatin-treated mice.Histopathological examination showed that Danshen mitigated the renal damage induced by cisplatin.Moreover,Danshen restored the activities of antioxidant enzymes (GSH-Px and SOD) and normalized the MDA contents in renal tissues.Western blotting revealed that Danshen enhanced the expressions of Nrf2 and its target genes in cisplatin-exposed mice.It was suggested that Danshen protects against the cisplatin-induced renal impairment in the mice,which is potentially associated with the upregulation of Nrf2-mediated signaling pathway.

The study is aimed to ensure the quality and safety of medicinal plants by using ITS2 DNA barcode technology to identify Corydalis boweri, Meconopsis horridula and their close related species. The DNA of 13 herb samples including C. boweri and M. horridula from Lhasa of Tibet was extracted, ITS PCR were amplified and sequenced. Both assembled and web downloaded 71 ITS2 sequences were removed of 5. 8S and 28S. Multiple sequence alignment was completed and the intraspecific and interspecific genetic distances were calculated by MEGA 5.0, while the neighbor-joining phylogenetic trees were constructed. We also predicted the ITS2 secondary structure of C. boweri, M. horridula and their close related species. The results showed that ITS2 as DNA barcode was able to identify C. boweri, M. horridula as well as well as their close related species effectively. The established based on ITS2 barcode method provides the regular and safe detection technology for identification of C. boweri, M. horridula and their close related species, adulterants and counterfeits, in order to ensure their quality control, safe medication, reasonable development and utilization.

OBJECTIVETo analyze the un-healing cause and management after operation of thoracolumbar tuberculosis.

METHODSFrom January 2008 to December 2011, the data of 12 patients with postoperative un-healing thoracolumbar tuberculosis were retrospectively analyzed. There were 5 males and 7 females, with an average age of 51.3 years old (ranged, 42 to 65). All the patients occurred different degree of vertebral destruction, abscess-formation, kyphosis and nerve functional injury at the first operation. Among them, 11 patients underwent debridement and fusion with autogenous iliac bone grafting and internal fixation, 1 patient underwent debridement and fusion with autogenous iliac bone grafting. At 2-6 months after operation, internal fixation loosening, fusion failure, abscess-ormation, or erythrocyte sedimentation rate increasing occurred in the patients. For the patients to adjust anti-tuberculosis scheme, 2 patients were treated with puncture to multiple abscess combining with rifampicin local injection; 10 patients were reoperated with debridement and internal fixation adjusting.

RESULTSAt 1-2.5 years (mean 1.8 years) after follow-up, 9 cases were cured finally. Re-admission had 3 cases because of re-occurred erythrocyte sedimentation rate increasing and abscess-formation at the 2-4 months after operation, whose bacterial culture showed more than 2 kinds of drug fast, and the treatment effect was still not ideal after adjusting anti-tuberculosis scheme.

CONCLUSIONInsufficient anti-tuberculosis and bad nutritional status before operation,incomplete debridement and unreasonable fixation style during operation, inadequate drainage, irregular anti-tuberculosis and drug fast of Bacillus tuberculosis after operation are main reasons leading to un-healing of tuberculosis. Therefore, actively improving malnutrition, making individual operation plan before operation, ensuring complete debridement, rebuilding spinal stability, removing the compression of spinal cord, combining with postoperative effective, enough, regular combination chemotherapy are important guarantee to cure of spinal tuberculosis.
