Methods: Papers on the research of HUA prevention and treatment with medicine-food homology from December 15, 2002 to August 10, 2024 were screened and collected through China National Knowledge Infrastructure (CNKI), PubMed, ScienceDirect, and Google Scholar. Subsequently, the impact of these medications and their extracts, as well as the active compounds on HUA were assessed. Results: A total of 148 relevant papers were collected, including 43 kinds of Chinese medicines and 61 active compounds, all of which have anti-HUA activity. Among them, 41 kinds of Chinese medicines could inhibit the activity of xanthine oxidase, thus leading to the inhibition of uric acid production; and 22 kinds of Chinese medicines could facilitate uric acid excretion, while 15 kinds of Chinese medicines could reduce the inflammation levels in the body and promoting renal protection. Notably, polyphenols and flavonoids are the key active components for the uric acid-lowering effects. Conclusion This study systematically summarized and analyzed the uric acid-lowering effects and mechanisms of Chinese medicines with medicine-food homology, laying a foundation for their development as HUA agents.

Objective To explore the sensitivity and specificity of colposcopy directed biopsy (CDB) and the value of loop electrosurgical excision procedure (LEEP) for the diagnosis and treatment of microinvasive cervical cancer (MCC). Methods One hundred and thirty five patients with MCC were diagnosed with LEEP in Obstetrics and Gynecology Hospital, Fudan University from April 2008 to November 2010, and were retrospectively analyzed on CDB diagnoses and following treatment after LEEP. According to patient′s desire for preservation of fertility and cone margin status, following strategies after LEEP included follow-up, second LEEP, hysterectomy, modified radical hysterectomy and radical hysterectomy. Single and multiple factors related to residual lesions after LEEP were analysed with Pearson Chi-square test and logistic regression model, respectively. Results CDB diagnosed MCC with a sensitivity of 4.4%(6/135), specificity of 100.0%(4 680/4 680), and false negative rate of 95.6%(129/135). Among the 135 patients, 29 did not receive further treatment in our hospital and lost contact. One hundred and six patients had secondary treatment or follow-up in our hospital, 4 of among which were closely followed up;one hundred and two received further treatment, which included 6 cases with second LEEP (3 received extrafascial hysterectomy after repeat LEEP), 59 cases hysterectomy, 14 cases modified radical hysterectomy and 26 cases radical hysterectomy. For factors related to residual lesions after LEEP, single factor analysis showed that the ratio of residual lesion in patients aged 27-39, 40-49 and 50-65 years were respectively 19.0%(11/58), 15.4%(10/65) and 5/12 (χ2=4.505, P=0.105). Residual lesions occurred in 24.7%(23/93) of patients with positive LEEP margins, which was more than that 7.1%(3/42) of patients with negative LEEP margins (χ2=5.756, P=0.016). The ratio of residual lesions in patients with positive endocervical, ectocervical and deep stromal margins were respectively 29.6%(8/27), 17.1%(7/41)and 30.6%(11/36;χ2=2.275, P=0.321). Residual lesions in patients with or without lymph vascular space invasion (LVSI) were 2/7 and 18.8%(24/128), respectively (χ2=0.412, P=0.521). The ratio of residual lesions in patients with invasion depth of<1 mm was 17.1%(7/41), 1-<3 mm was 19.0%(16/84), and 3-5 mm was 3/10, with no significant difference among three groups (χ2=0.870, P=0.647). Logistic regression analysis showed positive cone margin (OR=5.069, P=0.014) and age (OR=1.080, P=0.024) were the independent risk factors of residual lesions after LEEP conization. Conclusions CDB alone is not adequate for the diagnosis of MCC. For young patients who desire to preserve fertility with a negative cone margin, close follow-up is acceptable. Cone margin status and age are two independent risk factors for residual lesions after LEEP.

Objective To explore the efficacy of cold packs combined with ice compress in treatment of pain after erbium fractional photothermal therapy on acne scars. Methods Eighty cases which were confirmed to the criteria were randomized into two groups:treatment group and control group. The treatment group (n=40) treated with cold packs combined with cold icy compress immediately after the surgery for 30~40 mins. The control group (n=40) was given icy compress therapy immediately after the surgery for 30~40 mins. The therapy continued for three days after the surgery on the two groups. The self-feeling symptom and pain relieving time were compared between the two groups. Result The time for pain relief in the wounds and the time for scabbing were both significantly shorter than those in the control group (P<0.01). Conclusion The cold packs combined with ice compress therapy can relieve the pains effectively and it can shorten the recovery time after fractional photothermal therapy.

Objective To investigate the status of dietary fiber ( DF ) and dietary glycemic load ( GL ) in middle-aged and elderly population, and to analyze the correlation of DF and GL with abnormal glucose metabolism. Methods Subjects aged 40-79 years came from Guangzhou community. Dietary nutrients intakes were assessed by continuous 24 hours review for 3 days. Correlation of abnormal glucose metabolism with GL and DF and their interaction were analyzed as quintiles of the distribution. Results Of 1 832 subjects, there were 990 subjects (54. 0%) with normal glucose tolerance, 640 (34. 9%) with IGR, and 202 (11. 0%) newly-diagnosed diabetes mellitus(DM). AverageDFintakeofsubjectswas(11.5±4.5)g/dandaverageGLintakewas(181.0±7.5)/d. Compared with the highest quintile group of total DF intake, the risk of abnormal glucose metabolism in the lowest quintile group was increased[OR=1. 99, 95% CI (1. 48,2. 67)], with increased IGR risk[OR=1. 85, 95% CI (1.34,2.57)]andDMrisk[OR=2.36,95% CI(1.50,3.73)]. ComparedwiththelowestquintilegroupofGL intake, the risk of abnormal glucose metabolism in the highest quintile group was increased [ OR=1. 58, 95% CI (1. 18, 2. 13)], and with increased IGR risk[OR=1. 75, 95%CI(1. 26, 2. 42)] and DM risk[OR=1. 22, 95%CI(0. 77, 1. 94)]. The lowest quintile of DF and the highest quintile of GL was associated with the risk of increased abnormal glucose metabolism[OR=3. 43, 95%CI(1. 41, 8. 36)]. Conclusion Abnormal glucose metabolism was negatively related with DF and positively related with GL.

Objective To investigate the effect of dietary glycemic load (GL) on the blood glucose level in women with impaired glucose regulation. Methods A total of 120 women with impaired glucose regulation aged from 40 to 79 were enrolled from Guangzhou community to participate in the epidemiological survey on dia-betes mellitus, and were followed up for 12 months. Continues 24 -hour dietary review of 3 days were completed before and after intervention. The dietary GI, GL and the changes of blood glucose level during the 12-month follow-up were analyzed. Results Ninety-nine subjects completed the 12-month follow-up. According to the GL change percentage (ΔGL), all of the subjects were divided into three groups, including group Ⅰ(ΔGL < -30%)、group Ⅱ(ΔGL -30% ~ -10%) and group Ⅲ (ΔGL≥-10%). The reductions of HbA1c in group Ⅰ and groupⅡ were greater than that in group Ⅲ (P < 0.05). Conclusion To lowering dietary GL at 10% or more should be conductive to reduce HbA1C of women with inpaired glucose regulation.
