Objective:To investigate the prevalence of hyperuricemia (HUA) in Bozidun Kirghiz township of Xinjiang Aksu region, and to explore the risk factors for the occurrence of HUA in the local area.Methods:A cross-sectional survey study was conducted by randomly selecting 9 villages in Bozidun Kirgiz Township by the whole-group sampling method and questionnaire were distributed to the households. The questionnaire included: demographic information, history of past illness, personal history, and all subjects were measured for height, weight, blood pressure, abdominal circumference, etc. The diagnostic of HUA if the serum uric acid (SUA) level >420 μmol/L in men or >360 μmol/L in women. The incidences of HUA in different age, sex, food type and life style behavior were analyzed. T test, non-parametric test and Chi-square test were used to analyze the differences among the groups, and logistic regression was used to analyze the risk factors. Results:①A total of 2 138 subjects were surveyed, among which 68 patients were with HUA, the prevalence of HUA in Bozidun Kirghiz township, Aksu region in the general population was 3.18%(68/2 138); the prevalence rate in men was 4.60%(45/978), 45 patients were identified; and the prevalence rate in women was 1.98%(23/1 160), 23 patients were identified. The peak age of HUA in male and female patients was 51~60 years old. ②The prevalence of HUA was lower in those who consumed dairy products ( χ2=6.91, P=0.017), nuts ( χ2=8.43, P=0.038) and eggs ( χ2=7.38, P=0.023), and lower in those who consumed more. Different intake of cereals ( χ2=0.87, P=0.647), meat( χ2=0.82, P=0.662), vegetables and fruits( χ2=5.22, P=0.073) had no effect on the prevalence of HUA.③In terms of different life behaviors, the prevalence of HUA in men who had been smoking was higher than those who had never smoked (57.78%, 28.89%, 13.33%, χ2=8.16, P=0.017). In the relationship between drinking and HUA, the prevalence rates of male always drinking, ever drinking and never drinking were 80.00%, 11.11% and 3.89%, respectively, the difference was statistically significant ( χ2=6.67, P=0.038). ④Multi-factor logistic regression analysis showed that high BMI, old age, high TG, increased Cr and increased WBC were risk factors for the occurrence of HUA [ OR(95% CI)=1.13(1.04, 1.23), 1.03(1.00,1.05),1.39(1.00, 1.93), 1.03(1.02, 1.05), 1.27(1.07, 1.49), all P<0.05]. Conclusion:The prevalence of HUA in Bozidun Kirgiz township in Aksu prefecture of Xinjiang is lower than that in other areas with continental climate. High BMI, old age, high TG, increased Cr and increased WBC count are risk factors for the development of HUA .

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

The multiple myeloma (MM), the second most common hematologic malignancy, is malignant proliferative disease of plasma cells. Although the application of many targeted drugs has significantly prolonged the survival time of MM patients, it is still an incurable disease. In recent years, the immunosuppression caused by interaction between tumor microenvironment(TME) and tumor cells has attracted people's attention gradually. As a kind of immunosuppressive cells in TME, regulatory T cells (Treg) play an important role in the progress of MM. Treg is related to the proliferation and metastasis of tumors, and can lead to the progress of MM by promoting the angiogenesis and generating immunosuppressive TME. In this review, we briefly summarized the latest research progress on the impact of Treg on the pathogenesis of MM.

OBJECTIVE: To investigate the surgical skills and clinical curative results of arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome. METHODS: From February 2019 to August 2020, 13 patients with ankle instability combined with anteromedial impingement were retrospectively analyzed. There were 10 males and 3 females with age of (40.0±15.1) years old. The course of disease was(44.1±33.2) months. All patients had history of ankle sprain. MRI showed the injury of anterior talofibular ligament. All patients had anteromedial pain and pressing pain when ankle dorsiflexion. All patients were treated with ankle debridement and Brostr?m-Gould surgery under ankle arthroscopic. Postoperative results were evaluated by VAS(visual analogue scale) and AOFAS-AH(American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, AOFAS-AH). RESULTS: All 13 patients completed the surgery successfully with an operative time of 60 to 90 minutes. All the surgical incisions healed by first intention, and no complications such as incision infection, skin necrosis and neurovascular injury. Follow-up time was (18.1±4.7) months. At the latest follow-up, the VAS score was 1.2±1.1, which was significantly lower than the preoperative score 4.8±1.5 (P<0.05);the AOFAS-AH score 94.2±5.1 was significantly higher than the preoperative score 65.5±11.5 (P<0.05). The AOFAS-AH score at the final follow-up ranged from 84 to 100. All patients walked with normal gait without ankle instability or impingement recurrence. CONCLUSION Ankle anteromedial impingement syndrome combined with ankle instability is easy to be ignored clinically. Such kind of anteromedial impingement syndrome is mostly related to osteophyte at dorsal medial talar neck. Arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome has satisfactory curative effect with safety and minimal injury.

OBJECTIVE: To explore early efficacy of minimally invasive Chevron Akin(MICA) osteotomy for the treatment of mild to moderate hallux valgus. METHODS: From June 2019 to April 2021, a total of 26 patients (29 feet) with mild to moderate hallux valgus, including 1 male and 25 females aged from 19 to 78 years old with an average of(38.3±19.5) years old, were treated with MICA. Preoperative and postoperative hallux valgus angle(HVA), intermetatarsal angle(IMA) and shortening of the first metatarsal were observed and compared. American Orthopedic Foot and Ankle Society (AOFAS) forefoot scoring system and visual analogue scale (VAS) were applied to evaluate clinical outcome at the final follow-up, and complications were also recorded. RESULTS: All patients obtained followed up from 12 to 33 months with an average of(19.6±5.1) months. HVA and IMA was improved from (32.3±6.6)° and (11.7±3.2)° pre-operatively to (13.0±5.3)° and (6.1±3.2)° post-operatively, respectively, which had a significant difference (P<0.01). The average shortening of the first metatarsal was (2.7±1.1) mm. AOFAS and VAS was improved from (55.7±7.4) and (6.5±1.5) preoperatively and to (88.5±7.9) and (0.7±0.4) respectively at the final follow-up, which also had a significant difference(P<0.01). According to AOFAS score, 15 feet achieved an excellent result, 11 good and 3 moderate. CONCLUSION MICA osteotomy is a safe and reliable surgical technique for mild to moderate hallux valgus with advantages of minimally invasive, rapid recovery, low complication rate and an effect improvement of hallux valgus deformity.

This study aimed to propose an operational definition of late-onset hypogonadism (LOH) that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China. A population-based sample of 6296 men aged 40 years-79 years old was enrolled from six representative provinces in China. Serum total testosterone (TT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were measured and free testosterone (cFT) was calculated. The Aging Males' Symptoms (AMS) scale was used to evaluate the LOH symptoms. Finally, 5078 men were included in this analysis. The TT levels did not decrease with age (P = 0.59), and had no relationship with AMS symptoms (P = 0.87 for AMS total score, P = 0.74 for ≥ 3 sexual symptoms). The cFT levels decreased significantly with age (P < 0.01) and showed a negative association with the presence of ≥ 3 sexual symptoms (P = 0.03). The overall estimated prevalence of LOH was 7.8% (395/5078) if a cFT level <210 pmol l

OBJECTIVE: To explore the effects and mechanisms of PKC412 inhibitor on proliferation and apoptosis of HL-60 cell line. METHODS: CCK-8 assay was used to detect the effect of PKC412 on the proliferation of HL-60 cells at different concentrations; Wright-Giemsa staining was used to estimated the effect of PKC412 on the apoptosis of HL-60 cells; the mRNA expression of BCL-2 and P53 genes was detected by qRT-PCR, the expression of BCL-2 and P53 proteins was detected by Western blot. HL-60 cells were injected into mouse caudal vein to construct acute myeloid leukemia model, PKC412 was administered to tail vein for 31.25 nmol/kg, normal saline was injected into the same site of the mice as control group, and the inhibitory effect of PKC412 on HL-60 cells in mice was observed. ELISA assay was used to detect the effect of PKC412 on the inflammatory factors of TNF-α and TGF-β in tumor mice. RESULTS: PKC412 could inhibit the proliferation of HL-60 cell, which was in a dose dependent manner(r=0.9973) (IC50 was 0.31 μmol/L), and induce apoptosis of HL-60 cells. After HL-60 cell was treated by PKC412 for 48 h the expression of BCL-2 gene was down regulated(0.417±0.044 vs 0.933±0.033, t=9.347, P<0.001), the expression of P53 gene was up regulated(1.533±0.145 vs 1.050±0.161, t=2.231, P>0.05) as compared with control group. And the expression of BCL-2 protein was decreased, while the expression of P53 protein was increased. PKC412 could inhibited the growth of HL-60 tumor cells in vivo, the survival rate of mice after administration was 50% and the weight was increased as compared with that in control group(18.02±0.403 g vs 16.44±0.562 g, t=2.272, P=0.0356). The secretion of TNF-α and TGF-β cytokine in serum and spleen cells in PKC412 group was significantly lower than that in control group (P<0.05). CONCLUSION PKC412 can induce apoptosis of HL-60 cells by inhibiting the expression level of BCL-2 gene, PKC412 administration in vivo can inhibit the growth of the tumors.
