The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

Objective:To explore the risk factors for hypogonadism in male patients with hyperuricemia(HUA).Methods:A total of 245 male patients with HUA were enrolled. Height, weight, waist circumference (WC), blood pressure, serum uric acid(SUA), triglyceride (TG), total cholesterol, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, alanine aminotransferase(ALT), aspartate aminotransferase, glutamyltranspeptidase, blood urea nitrogen, serum creatinine, fasting blood glucose (FPG), fasting insulin (FINS)and sex hormones were measured in all patients. And then body mass index (BMI), free testosterone(FT), and homeostasis model assessment of insulin resistance index (HOMA-IR)were calculated. Male androgen deficiency questionnaire (ADAM)and male aging symptom questionnaire (AMS)were conducted. The patients were divided into hypogonadism group ( n=102)and normal gonadal function group ( n=143) according to FT level as well as ADAM and AMS questionnaires. The differences in different metabolic indicators between the two groups and the correlation with hypogonadism were analyzed. Results:Compared with the normal gonadal function group, WC, SUA, BMI, FPG, FINS, HOMA-IR, TG, and ALT were significantly increased, while estradiol level was significantly reduced in the hypogonadism group (all P<0.05). The proportions of nonalcoholic fatty liver, hyperlipidemia, and obesity were significantly increased in the hypogonadism group (all P<0.05). Logistic regression analysis showed that SUA, BMI, WC, HOMA-IR, and TG were independent risk factors for hypogonadism in male HUA patients. Multivariate regression analysis showed that SUA still was a risk factor after adjusting for other factors. Conclusion:Male patients with HUA were often accompanied by hypogonadism. SUA, BMI, WC, HOMA-IR, and TG were risk factors for hypogonadism in male patients with HUA.

Objective To analyze the clinical characteristics of familial and sporadic gout patients to provide information for the classification,individual treatment and prognosis of gout.Methods The clinical and biochemical characteristies of 431 patients with familial gout and 1899 patients with sporadic gout were compared and analyzed.T test and X2 test were used for statistical analysis.Results The age at onset [(47±13) years ] and the serum uric acid level [ (472±125) μmol/L] of the familial gout patients in the acute phase were significantly lower than those of the sporadic gout patients (P＜0.05).The percentage of patients whose attack were induced by purine-rich food (67.7％ vs 88.2％),drinking (31.3％ vs 44.5％) and the first metatarsophalangeal joint involvement (69.1％ vs 77.4％ ) were significantly lower in the familial gout patients than those in the sporadic group of patients.The percentage of female was lower in the familial gout (9.7％) than in the sporadic patients(6.6％,P＜0.05).The percentage of patients with ankle joint (18.1％ vs 11.3％) and no obvious predisposing causes (25.2％ vs 2.5％ ) were higher in the familial gout patients than in the sporadic patients (P＜0.05).The percentage of patients with complicated lipid metabolism disorders was significantly higher in the familial gout patients than in the sporadic patients (P＜0.05).Conclusion The familial gout patients in Shandong coastal regions are early in disease onset,with lower serum uric acid level and more frequent in women.Detailed family history should be collected,and early prevention and appropriate treatment should be emphasized.

Objective To explore the anatomical basis for clinical application of the compound flap pedicled with arterial arch of palpebral margin by observing eyelid blood supply and anatomical structure and to prove that it is an ideal method of repairing the eyelid defect for clinical application. Methods 15 adult cadavers (30 eyelids) were dissected. The origin, course, branches, diameters and vessel networks of palpebral margin arterial arch were observed particularly. 30 cases of eyelid marginal defect were reviewed and the therapeutic effect of this method evaluated. Results Eyelid was constituted by 5 layers: skin, subcutaneous tissue, muscle, tarsal plate and conjunctival layers. Most eyelid vessels were mutually anastomosed to form a constant vessel network. Palpebral margin arterial arch and peripheral arterial arch were formed by dorsal nasal artery branches and lacrimal artery branches, both of which nourished the eyelid tissue. All the compound flaps of 30 cases survived completely without any complications. All cases obtained satisfactory results functionally and esthetically. Conclusions The arterial arch of palpebral margin is constant and the blood supply of the compound flap is reliable. It can repair full eyelid defect with the same kind of tissue, and obtain satisfactory appearance. It is an ideal method of repairing the eyelid defect.

OBJECTIVETo introduce a method of repairing facial tissue defects caused by various factors.

METHODSThe reverse narrow pedicle lateral maxillocervical fasciocutaneous flap was designed with its pedicle located in front of auricle. The size of the flaps ranged from 5 cm x 6 cm to 10 cm x 11 cm. The length and width of the pedicle ranged 2 cm-5 cm and 1 cm-1.5 cm.

RESULTSThis fasciocutaneous flap was used in 21 cases. All flaps survived except 1 flap showing distal skin necrosis.

CONCLUSIONThis fasciocutaneous flap didn't include any major blood vessel. The ratio of the pedicle width to flap length broke that of traditional flap and was reverse transfer. The transposition of the narrow pedicle flap was easy. The postoperative appearance (color, texture, cosmetic aspect) was satisfactory. This method was a new design and was ideal for large facial tissue defect repair.

Objective To investigate the method of repairing moderate or severe full defect of eyelid. Methods According to eyelid structure and the defect size, the two composite eyelid flaps were designed beside defect based on the arterial arch of the palpebral margins. If the defective area was too large, the lateral composite flap may be extended to lower or upper eyelid at the outer canthus, then the two flaps were propelled to the defective region to repair it. Results Eleven patients had been cured with this method since 1998. The largest length of eyelid defect was 1.7cm, and the smallest was 0.8cm. All defects exceeded 1/3 length of the upper or lower eyelid. All composite flaps survived completely without any complication. The appearance of the repaired eyelid was satisfactory. Conclusion Using the composite flap to repair the full moderate or severe full defect of eyelid is a new and effective method. It can not only provide enough tissues to repair large full defect of the upper or lower eyelid and to restore normal anatomical structure and appearance of the eyelid, but also is easy to be operated without severe secondary deformities, and the blood supply of the composite flap is reliable. The method is worth employing routinely.

Objective To introduce the anatomic basis and evaluat ion of clinical application of the pudendal-thigh island flaps us ing for vaginal reconstruction. Methods The blood supply and innervation to the skin and fascia of the pudendal-thigh region were studied in 5 female cadavers (with 10 sides). 20 patients who underwent vaginal reconstruction with pudendal-thigh island flaps were followed-up, and all the women were married for more than 3 years. Results There were multiple blood supply in the pudendal-thigh area. The cuta neous arterial vessels come from the posterior labial artery, the external pudendal artery and the anterior cutaneous branches of obturator artery. The posterior labial artery was one of the internal pudendal artery branches, a nd the diameter of it was 0.9～1.7 mm (1.3mm in average) in its original site, w hich was 22～35 mm (26mm in average) from the perineal midline. It gave off 4 ～7 branches to the major labia and the pudendal-thigh area while running alon g the lateral site of the major labia accompanying vein and nerve. 20 patients w ho were followed-up satisfied with their perineal appearance and with 10. 2 cm depth of neovagina in average. Twenty neovagina remained supple, and sexually active without difficulty. Conclusions The pedicle of the pudendal-thigh island flaps using for vaginal reconstruction is the post erior labial neurovascular bundle. The flap has reliable blood supply, survive s easily, transfers with partial sensation and few complications. This tech nique introduces a modified approch of vaginal reconstruction using bilateral pudendal- thigh island flaps with satisfactory cosmetic and functional resu lts.

Objective To report the anatomy and clinical application of the marginal mandibular flap pedicled with facial artery in nose reconstruction. Methods Based on the anatomical study of facial artery, the reversed marginal mandibular island flap pedicled with facial artery was designed, and the nasal reconstruction with the flap was operated in 20 cases. Results In 20 cases, the maximal size of flap was 7.0 cm?6.5 cm, and the minimal size was 6.0 cm?4.5 cm, and except the distal part necrosis in one flap, and wound dehiscence in nasal collumella in another flap, all other flaps survived. Followed up for 3 months to 2 years, all reconstructed noses showed satisfactory shapes. Conclusion The method is a new design technique for nose reconstruction with ideal nose appearance, and worth to be recommended.

Objective To introduce a method of repairing the secondary vermilion defect caused by bilateral cleft lip. Methods The two side vermilion flaps beside the defect were cut along the vermilion boundary, and the lip artery was involved in the flaps. The flap may be extended to lower lip if the defect was much large. Then the two flaps were propelled to repair the defective region. Results This method was used in 15 cases, in which the biggest width of the defect was 1.2 cm, and the smallest was 1.0 cm, with all the flaps survived. The postoperative appearance of the upper lip was satisfactory. Conclusion The lip artery is constant, so the blood supply of the flap is reliable and anatomizing the flap is easy. This is a new method and can be widely used in repairing vermilion defects.
