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 speech features of female patients with anhedonic depression and their recognition of pleasure deficient symptoms.Methods:A total of 102 female depression patients who were hospitalized at Nanjing Brain Hospital from September 2020 to October 2021 were selected, including 62 anhedonic depression patients (anhedonic group) and 40 non-anhedonic depression patients (non-anhedonic group). A total of 50 female healthy controls were recruited during the same period.All participants were evaluated by the 17-item Hamilton depression scale (HAMD-17), Snaith-Hamilton pleasure scale (SHAPS), and the temporal experience of pleasure scale (TEPS), as well as voice acquisition.SPSS 23.0 software was used for data processing.Statistical analysis was conducted using one-way ANOVA, non-parametric tests, Logistic regression, and receiver operating characteristic curve.Results:Compared with the non-anhedonic group, the anhedonic group showed significant changes in 15 voice features(all P<0.05), including Mel-frequency cepstral coefficients, formant frequencies, intensity, and energy features.Among these features, Mel-frequency cepstral coefficients exhibited the highest accuracy in identifying anhedonic depression, with sensitivity of 47.5%, specificity of 91.9%, area under curve (AUC) of 0.751, 95% CI=0.686-0.866.Formant frequencies could identify female anhedonic depression, with a sensitivity of 90.0%, a specificity of 40.3%, an AUC of 0.647, and 95% CI=0.605-0.824.Energy features could identify anhedonic deficient depression, with a sensitivity of 60.0%, a specificity of 74.2%, an AUC of 0.679, and 95% CI=0.587-0.804.Intensity features could identify female anhedonic depression, with a sensitivity of 70.0%, a specificity of 58.1%, an AUC of 0.640, and 95% CI=0.554-0.769. Conclusion:Mel-frequency cepstral coefficients, formant frequencies, intensity features, and energy features may have specific changes in female patients with anhedonic depression.The Mel-frequency cepstral coefficients has the highest recognition accuracy for anhedonic symptoms in female depression patients, and is expected to become an objective evaluation index for female anhedonic depression.

In clinical application, a microneedle system that continuously delivers drugs is of great value for the delivery of some vaccines and hormone drugs. In this study, a controlled-release chitosan-based microneedle array (PVA/CS-MN) was designed, combining microneedle patches with drugs for controlled-release of drugs. Here we report the optimization of the preparation process of PVA/CS-MN. The appearance, morphology, mechanical properties, dissolution and swelling properties, and in vitro penetration properties of the MN arrays were characterized. The PVA/CS-MN prepared by the optimal process showed good morphology and mechanical properties. PVA/CS-MN can smoothly open microchannels on the skin and achieve controllable dissolution and swelling functions. Ascorbic acid (l-ascorbic acid) was used as a model drug to prepare a Vc-PVA/CS-MN. In vitro transdermal diffusion experiments showed that the Vc-PVA/CS-MN released about 57% of the drug within 1 h. About 66.7% of the drug was slowly released within 12 h, and a total of 92% of the drug was released after 7 days. The controllable sustained-release properties and excellent drug delivery efficiency of PVA/CS-MN provide a new option for sustained transdermal drug delivery.

At weeks 0, 4, 8 and 12, the psoriasis area and severity index (PASI) was recorded, and adverse drug reactions were observed.Results:All 7 patients were treated for at least 12 weeks. After 4-week treatment, 4 patients achieved PASI50; after 12-week treatment, 5 achieved PASI75, and 2 achieved PASI90. No serious adverse drug reactions occurred. One patient developed fever during the treatment, but the body temperature returned to normal after management; another 1 developed cough and expectoration, and the symptoms were relieved after oral administration of a Chinese herbal preparation named pharyngitis mixture.Conclusion:Secukinumab is effective in the treatment of erythrodermic psoriasis, with fewer adverse reactions, which provides a new option for the treatment of erythrodermic psoriasis.

Immune thrombocytopenia (ITP) is an autoimmune disease mediated by acquired immunity, with platelets decreased and hemorrhage being the primary clinical manifestations. The responses and platelet count levels after early treatment are important factors affecting long-term prognosis, however, current diagnostic methods and disease evaluation approaches are limited, and lack of specific biomarkers. In recent years, various biomolecules have been proposed as potential biomarkers for ITP. This paper reviews the value and advances in ITP-related biomarkers.

Objective To investigate the value of endoscopic retrograde appendicitis therapy ( ERAT) in the diagnosis and treatment of atypical acute appendicitis. Methods All the 48 patients suspected of atypical acute appendicitis in Jiangsu Province Hospital from January 2015 to December 2016 were randomly divided into ERAT group and conservative treatment group according to the treatment method. The final appendectomy rate of the two groups was analyzed. Results Only 17 of the 24 patients in the ERAT group received endoscopic treatment because of complex conditions or personal wishes, and 16 cases were diagnosed as acute appendicitis. Surgical resection was performed in 5 cases because of recurrence of the disease after ERAT, and the appendectomy rate was 31. 2％ ( 5/16 ) . In the conservative treatment group, all 24 patients were treated with antibiotics. Twenty of them underwent surgical resection with appendectomy rate of 83. 3％ ( 20/24) , and 1 of them had appendiceal perforation. The appendectomy rate of the ERAT group was significantly lower than that of the conservative treatment group (χ2=11. 111, P<0. 05) . Conclusion ERAT has a high diagnostic and therapeutic value for atypical acute appendicitis.

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 explore the skill of mien)surgical removal and preservation and functional recovery of facial nerve for large acoustic neuromas.Methods The clinical data of 82 consecutive patients with large acoustic neuromas operated upon through the suboccipital retrosigmoid approach were retrospectively reviewed.The cases with HB grade Ⅲ - Ⅵ of facial nerve were divided randomly into two groups,the one group was given conventional therapy and the other group was given Kabato rehabilitation training.Results In those cases,acoustic neuromas were totally removed in 77 (93.9%),subtotally removed in 5.Facial nerve was kept anatomically intact in 78 cases of the patients (95.1%).Recovery of facial nerve function was faster and more effective in the training group than that in the un-training group.During the follow-up ranging from 6 months to 3 years,among 5 cases of subtotally resection,2 cases relapsed.Three patients in our series complained of chronic headache postoperatively.No patient long time coma or died.Conclusion The goal of large acoustic neuromas treatment should be total removal in one stage and preservation of facial nerve function,as they determine a patient's quality of life.Kabat rehabilitation training is the effective method of functional recovery of facial nerve after operation.

BACKGROUND: A stable and exact animal model is the necessary tool and basis for studying hemorrhagic cerebrovascular diseases.OBJECTIVE: To establish and evaluate the intracerebral capsular hemorrhage models in rats.DESIGN: A randomized and controlled animal experiment.SETTING: Second Hospital Affiliated to Xuzhou Medical College; First Hospital Affiliated to Nanjing Medical University.MATERIALS: This experiment was carried out in the animal experimental center of Nanjing Medical University during May to November 2002.Totally 35 SD rats were randomized into two groups: experimental group (n=30) and sham-operation group (n=5).METHODS: ① Autoblood was injected into the intracerebral capsule of rats to create intracerebral capsule hemorrhage models with stereotaxy in the experiment group. ②Scoring was conducted according to 5-point neurological scoring criteria from ZeaLonga, somatic sensation and motor function of rats were observed. ③Somatosensory evoked potential(SEP) of rats was detected pre- and post-operation under anesthetic state. ④ After determination of SEP, the rats were sacrificed under anesthetic state. Brains were taken out to made slices, then sections were stained with haematoxylin and eosin. Changes in haematoma and histomorphology were observed at the largest focus under optical microscope.MAIN OUTCOME MEASURES: ①Nerve function scoring; ②Latent period of various waves of SEP; ③ Observation of brain tissue morphology.RESULTS: Totally 35 rats entered the stage of result analysis. ①Appearance of obvious paralysis of the rats suggested the modeling was successful. The successful rate of this experiment was 93.3%(28/30). Significant difference existed in neurological scoring between experimental group [(2.74±0.46)points] and sham-operation group (0 point)(P＜0.05). ②SEP showed that the latent periods of various waves of experimental group after operation were significantly delayed than those before operation and those of sham-operation group [P1: (15.72±0.78) ms, (10.69±0.52) ms, (10.73±0.48) ms;Nl: (17.95±1.27) ms,(13.21±1.31) ms, (13.34±1.27) ms;N2:(21.16±1.62) ms, (15.42±1.46) ms,(15.58±1.44) ms;N3:(24.86±1.58) ms, (18.72±1.76) ms, (18.99±1.67) ms,P＜0.05]. ③In the shamoperation group, a few red blood cells were scattered in the peripheral area of needle channel were found, but hemorrhagic focus was not; In the experimental group, irregular or oval blood clots presented in the left internal capsule area. In about a low-fold visual field, brain tissue in the surrounding of hemorrhagic focus was loosened and swelled, and pathological changes were obviously severer than those in the sham-operation group.CONCLUSION: Intracerebral capsular hemorrhage induced by injection of autoblood with stereotaxy is more close to clinical situation, and it is easy to operate and has good reproducibility.
