Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Pancreatic cancer patients often have complaints such as upper abdominal pain and obstructive jaundice when seeking diagnosis and treatment. However, acute pancreatitis as a rare initial clinical manifestation of pancreatic cancer is often overlooked in clinical practice. This oversight often leads to a delayed diagnosis of pancreatic cancer, uncertainty in treatment strategies, and significantly affects patients′ quality of life and prognosis. Therefore, early diagnosis and treatment, and active follow-up are crucial for patients with acute pancreatitis as an initial symptom of pancreatic cancer. Upon admission to such patients, common causes such as gallstones, alcohol abuse, and hyperlipidemia should be initially ruled out. Evaluation with tumor markers, CT and MRI, and endoscopic ultrasound are essential to confirm the diagnosis of pancreatic cancer. For patients with mild pancreatitis, managing peripancreatic inflammation first before radical resection of pancreatic cancer could reduce postoperative complications. Moreover, pancreatitis serves as a high-risk factor for pancreatic cancer, so it is crucial to closely follow up patients with pancreatitis to detect pancreatic cancer early.

Objectives:To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer.Methods:The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ 2 test. Results:Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months, P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%, P<0.05;32.9% vs. 21.9%, P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%, P>0.05). Conclusions:The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients′ compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.

Objective:
To evaluate the role of multidisciplinary team (MDT) clinic in the diagnosis of pancreatic diseases and patient compliance with MDT advice in the current medical system.
Methods:
The study included 512 patients that had visited the pancreas-oriented MDT clinic of Zhongshan Hospital between May 2015 and May 2019.The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. Compliance was determined according to whether a patient received corresponding therapies or undergoing further checks or follow-ups.
Results:
Among the 512 patients that had visited the MDT clinic, 121 patients were referred due to undetermined diagnosis. Classified according to the final diagnosis, the rate of undetermined diagnosis in different disease categories from high to low in order was inflammatory diseases of the pancreas (75.0%, 24/32), other lesions of the pancreas (56.1%,23/41), pancreatic cystic lesions (19.1%,17/89), pancreatic carcinomas (18.3%,48/262) and pancreatic neuroendocrine neoplasms (pNEN)(10.2%,9/88). The MDT clinic made diagnosis to 68 patients directly with an accuracy of 89.7%. The rate of compliance in the entire cohort was 63.4%. The rate of compliance of patients from June 2017 to May 2019 (68.4%) was higher than that of patients from May 2015 to May 2017(59.6%). The compliance rate of patients in different disease categories from high to low in order was inflammatory diseases of the pancreas(84.4%, 27/32), pancreatic carcinomas (67.9%, 178/262), pNEN(60.2%,53/88), other lesions of the pancreas (56.1%,23/41), and pancreatic cystic lesions(49.4%, 44/89). The compliance rate of patients with different MDT advice from high to low in order was best supportive care(78.6%,22/28), antitumor approaches beyond surgery(71.6%,159/222), further tests(62.6%, 77/123), surgery(53.7%, 65/121) and follow-up(49.2%, 31/63). In patients suggested for surgery, the compliance rate of patients with carcinomas(67.4%, 33/49) was higher than patients with other kinds of neoplasms.
Conclusions
MDT clinic could facilitate the diagnosis of pancreatic diseases conveniently and inexpensively. The overall compliance rate of MDT clinic patients is rather low, and patients with carcinomas have a relative high rate of compliance with the suggestion of surgery.

The application of Aconitum herbs in the treatment of Bi syndrome has a long history and exact effects.By taking Aconiti Radix(Chuanwu), Aconiti Kusnezoffii Radix(Caowu) and Aconiti Lateralis Radix Preparata(Fuzi) as example, this study was aimed to mine the prescription rules of Aconitum herbs in the treatment of Bi syndrome, and provide thoughts and bases for modern clinical medication. 1 106 prescriptions were obtained in more than 20 classic books including medical, pharmacy, and synthesized books from Eastern Han dynasty to Qing dynasty. Based on the methods of frequency statistics, percentile statistics and Apriori algorithm of association rules, the characteristics of syndrome classification, dosage and compatibility of Aconitum herbs in the treatment of Bi syndrome were analyzed. The data-mining results indicated that 60.76% prescriptions contained Fuzi, which was obviously higher than Chuanwu or Caowu, and 17.63% contained two or more kinds of Aconitum herbs. 70.34% prescriptions were used mainly to treat Bi syndrome with wind-cold-wetness, others were for the syndrome with the deficiency of liver and kidney, blockage of phlegm and blood stasis, and wind-heat-wetness Bi. In the prescriptions with definite dose, 80% dosage of Fuzi was in the range from 0.29-2.14 g·d⁻¹, while the dosage of Chuanwu and Caowu was from 0.14-1.01g·d⁻¹, which was also affected by patterns, formulations and processing. The dose of Aconitum herbs was highest in the Bi syndrome with wind-cold-wetness, and its dose in the decoction and vinum was significantly higher than that in the pills and powders. The processed products were used in 93.11% prescriptions, and their dosage was higher than the raw ones. In the clinical treatment of Bi syndrome, Chuanwu and Caowu were often used with Saposhnikoviae Radix(Fangfeng), Liquiritiae Radix et Rhizoma(Gancao), Myrrha(Moyao) and Ephedrae Herba(Mahuang), while Fuzi was often used with Cinnamomi Cortex(Rougui), Achyranthis Bidentatae Radix(Niuxi), Fangfeng and Chuanxiong Rhizoma(Chuanxiong), which can both expel wind-dampness and relieve pain. All in all, Aconitum herbs are widely used in the treatment of Bi syndrome, which can relieve arthralgia and pain.

ObjectiveTo investigate the effects of Qiangjing Tablets (QJT) on sperm quality and the MAPK signaling pathway in the SD rat model of asthenospermia (AS).
METHODSA total of 100 male SD rats were randomly divided into five groups of equal number, blank control, AS model control, high-dose QJT, medium-dose QJT, and low-dose QJT. All the rats were intragastrically administered ORN at 200 mg/kg/d for establishment of the AS model except those in the blank control group, which were given 1% CMC sodium solution at 1 ml/100 g by gavage. Meanwhile the animals of the high-, medium-, and low-dose QJT groups were gavaged with QJT at 6700, 3300 and 1700 mg/kg/d, respectively, qd 6 days a week for 20 days. Then the testis issue and the apoptosis of the testicular cells were observed under the electron microscope, the expression of vimentin in the testis was determined with the immunohistochemical SP method, that of ERK1/2 detected by Western blot, and the concentration of TGF-β1 in the semen measured by ELISA.
RESULTSThe AS model controls showed round nuclei of spermatocytes, homogeneously distributed chromatins, broken or lost mitochondria, and expanded rough endoplasmic reticulum in the testis tissue. In comparison, the rats of the high-, medium-, and low-dose QJT groups exhibited round nuclei of spermatocytes, homogeneously distributed chromatins, and well-structured mitochondria, rough endoplasmic reticulum and ribosome, which were all similar those of the blank controls. Compared with the blank controls, the AS model rats manifested significantly increased expressions of ERK1/2 (1.00 ± 0.00 vs 1.26 ± 0.10, P<0.01) and vimentin (0.16 ± 0.01 vs 0.17 ± 0.01, P<0.01) and apoptosis rate of cells in the testis tissue ([9.20 ± 3.07] vs [42.20 ± 9.17] %, P<0.01), but decreased level of TGF-β1 in the semen ([627.67 ± 26.07] vs [566.73 ± 68.44] ng/ml, P<0.05). In comparison with the model controls, the rats of the high- and medium- -dose QJT groups presented remarkably down-regulated expressions of ERK1/2 (1.26 ± 0.10 vs 1.14 ± 0.08, P<0.01; 1.26 ± 0.10 vs 1.18 ± 0.05, P<0.05) and vimentin (0.17 ± 0.01 vs 0.16 ± 0.01, P<0.01; 0.17 ± 0.01 vs 0.17 ± 0.09, P<0.05) and decreased rate of cell apoptosis ([42.20 ± 9.17] vs [21.60 ± 5.94] %, P<0.01; [42.20 ± 9.17] vs [33.95 ± 6.39] %, P<0.05). The concentration of TGF-β1 in the semen was markedly lower in the high-dose QJT than in the AS model control group ([621.78 ± 30.80] vs [566.73 ± 68.44] ng/ml, P < 0.05).
CONCLUSIONSQiangjing Tablets could improve semen quality in asthenospermia rats by acting against oxidative stress.
