Objective: To investigate the clinicopathologic and molecular genetic characteristics, diagnosis, differential diagnosis, treatment and prognosis of histiocyte-rich rhabdomyoblastic tumor (HRRMT). Methods: The clinical data of two cases of HRRMT diagnosed in Fujian Provincial Hospital and Fujian University of Traditional Chinese Medicine Affiliated People's Hospital from 2020 to 2021 were collected. Histopathology and immunohistochemical (IHC) staining were used to assess morphological changes; the genetic changes were analyzed with next-generation sequencing. The relevant literature was reviewed. Results: Both cases showed well-defined solid nodules and soft masses. Microscopically, the tumors had a fibrous pseudocapsule with lymphocytic aggregation, and locally invaded the surrounding skeletal muscle tissue, and the tumor cells were fusiform to epithelioid with an intensive foamy histiocytic infiltrate. No necrosis or mitosis was observed. Immunophenotyping showed the tumor cells were positive for desmin, either one or both skeletal muscle markers (myogenin or MyoD1), and negative for h-caldesmon, ALK and SMA. The Ki-67 index was<5%. Using next-generation sequencing, one case was found to harbour KRAS (G12D) and MSH3 (Q470^*) mutations. Conclusions: HRRMT is a newly described skeletal muscle tumor with uncertain malignant potential. Its diagnosis and differential diagnosis depend on morphologic and IHC staining. No specific molecular genetics changes have been identified so far.

AIM:To observe the clinical effect of ranibizumab combined with 577nm micropulse laser in the treatment of severe diabetic macular edema(DME). METHODS:There were 52 eyes of 52 patients diagnosed with severe DME who admitted to the People's Hospital of Guangxi Zhuang Autonomous Region from June 2016 to September 2019. The patients were randomly divided into the observation group(26 patients with 26 eyes, treated with ranibizumab combined with 577nm micropulse laser)and the control group(26 patients with 26 eyes, treated with ranibizumab alone). Patients in both groups received intravitreal injection of ranibizumab with “3+PRN” regimen. Followed up at 9mo after treatment to observe the central macular thickness(CMT), the best corrected visual acuity(BCVA)and the times of intravitreal injection of ranibizumab in the two groups.RESULTS:Compared with before treatment, the CMT and BCVA of the two groups were significantly improved at each time point after treatment(all P<0.001), but there was no difference between the two groups(P>0.05). During the follow-up period, the times of vitreous injection of ranibizumabin the observation group was significantly less than that in the control group(5.88±1.24 times vs 7.12±1.24 times, P=0.001). CONCLUSION:Both ranibizumab combined with 577nm micropulse laser and ranibizumab alone are effective in reducing edema and improving vision in patients with severe DME, but the combination therapy reduces the times of injection.

Rib fracture is the most common injury in chest trauma. Most of patients with rib fractures were treated conservatively, but up to 50% of patients, especially those with combined injury such as flail chest, presented chronic pain or chest wall deformities, and more than 30% had long-term disabilities, unable to retain a full-time job. In the past two decades, surgery for rib fractures has achieving good outcomes. However, in clinic, there are still some problems including inconsistency in surgical indications and quality control in medical services. Before the year of 2018, there were 3 guidelines on the management of regional traumatic rib fractures were published at home and abroad, focusing on the guidance of the overall treatment decisions and plans; another clinical guideline about the surgical treatment of rib fractures lacks recent related progress in surgical treatment of rib fractures. The Chinese Society of Traumatology, Chinese Medical Association, and the Chinese College of Trauma Surgeons, Chinese Medical Doctor Association organized experts from cardiothoracic surgery, trauma surgery, acute care surgery, orthopedics and other disciplines to participate together, following the principle of evidence-based medicine and in line with the scientific nature and practicality, formulated the Chinese consensus for surgical treatment of traumatic rib fractures (STTRF 2021). This expert consensus put forward some clear, applicable, and graded recommendations from seven aspects: preoperative imaging evaluation, surgical indications, timing of surgery, surgical methods, rib fracture sites for surgical fixation, internal fixation method and material selection, treatment of combined injuries in rib fractures, in order to provide guidance and reference for surgical treatment of traumatic rib fractures.

Aim To explore the mechanism of asiatic acid (AA) on alcoholic hepatitis (AH) based on the network pharmacology and experimental verification in vivo methods. Methods The potential mechanism of AA on AH was explored by data collection, network construction, and enrichment analysis. Meanwhile, the model of alcoholic hepatitis disease was induced by in-tragastric administration of edible alcohol every day in SD rats. The key related indicators were detected, including biochemical markers, inflammatory responses, alcohol metabolism, pathological changes in liver tissues, and the expression of proteins of the NF-kB pathway. Results A total of 24 overlapping targets of AA and AH were screened out, and 20 signaling path ways and 12 GO functional entries were obtained. This study focused on the first pathway, hsa05200; Pathways in cancer. The pathway contained NF-kB signaling pathway. In vivo results showed that AA significantly reduced the serum levels of ALT and AST, increased the levels of alcohol metabolism and decreased the liver content of TNF-a and GSH. Additionally, AA significantly inhibited p-IKKa/(3, p-Ii

OBJECTIVE: To compare the therapeutic effect of electro-nape-acupuncture (ENA) combined with hyperbaric oxygen therapy (HBOT) and single HBOT on refractory flat descending idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: A total of 78 patients were randomized into an ENA combined with HBOT (ENA+HBOT) group and a HBOT group, 39 cases in each one. Patients in both groups were treated with oral extract of ginkgo biloba leaves and mecobalamin tablets. On the basis of the conventional medication treatment, HBOT was adopt in the HBOT group. On the basis of the treatment in the HBOT group, electro-nape-acupuncture was applied at Fengchi (GB 20), Gongxue (Extra), Zhongzhu (TE 3), Waiguan (TE 5) and Yifeng (TE 17), Tinggong (SI 19), Tinghui (GB 2) and the vertigo-auditory area of affected side in the ENA+HBOT group. Pulse acupuncture instrument was connected at Fengchi (GB 20) and Gongxue (Extra) for 30 min (with continuous wave, 2 Hz in frequency), the needles were retained for another 30 min after electroaupuncture. The treatment was given once a day, 6 times a week for 4 weeks in both groups. Before the treatment and 2,4 weeks into the treatment, the average auditory threshold, the scores of tinnitus handicap inventory (THI) and dizziness handicap inventory (DHI) were observed, and the therapeutic effect was evaluated in both groups. RESULTS: Compared before treatment, the average auditory threshold, the scores of THI and DHI of 2,4 weeks into the treatment were decreased in both groups (<0.000 1). Compared with the HBOT group, the average auditory threshold, the scores of THI and DHI of 4 weeks into the treatment were lower in the ENA+HBOT group (<0.000 1). The total effective rate was 69.2% (27/39) in the ENA+HBOT group and 51.3% (20/39) in the HBOT group, there was no statistical difference (>0.05). CONCLUSION Electro-nape- acupuncture can improve the mean auditory threshold and the symptoms of tinnitus and dizziness in patients with refractory flat descending idiopathic sudden sensorineural hearing loss.

OBJECTIVE: To assess the performance of a whole-tumor histogram analysis of apparent diffusion coefficient (ADC) maps in differentiating thymic carcinoma from lymphoma, and compare it with that of a commonly used hot-spot region-of-interest (ROI)-based ADC measurement. MATERIALS AND METHODS: Diffusion weighted imaging data of 15 patients with thymic carcinoma and 13 patients with lymphoma were retrospectively collected and processed with a mono-exponential model. ADC measurements were performed by using a histogram-based and hot-spot-ROI-based approach. In the histogram-based approach, the following parameters were generated: mean ADC (ADCmean), median ADC (ADCmedian), 10th and 90th percentile of ADC (ADC10 and ADC90), kurtosis, and skewness. The difference in ADCs between thymic carcinoma and lymphoma was compared using a t test. Receiver operating characteristic analyses were conducted to determine and compare the differentiating performance of ADCs. RESULTS: Lymphoma demonstrated significantly lower ADCmean, ADCmedian, ADC10, ADC90, and hot-spot-ROI-based mean ADC than those found in thymic carcinoma (all p values < 0.05). There were no differences found in the kurtosis (p = 0.412) and skewness (p = 0.273). The ADC10 demonstrated optimal differentiating performance (cut-off value, 0.403 × 10−3 mm2/s; area under the receiver operating characteristic curve [AUC], 0.977; sensitivity, 92.3%; specificity, 93.3%), followed by the ADCmean, ADCmedian, ADC90, and hot-spot-ROI-based mean ADC. The AUC of ADC10 was significantly higher than that of the hot spot ROI based ADC (0.977 vs. 0.797, p = 0.036). CONCLUSION: Compared with the commonly used hot spot ROI based ADC measurement, a histogram analysis of ADC maps can improve the differentiating performance between thymic carcinoma and lymphoma.
