Objective:To investigate the effects of Neibu Huangqi Decoction combined with Kangfuxin Liquid on wound healing after hemorrhoid fistula.Methods:Randomized controlled trial. A total of 90 patients with hemorrhoid fistula surgery in Tangshan Hospital of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation objects and divided into 2 groups by random number table method, with 45 cases in each group. The control group was treated with Kangfuxin Liquid after surgery, and the observation group was treated with Neibu Huangqi Decoction. Both groups were treated continuously for 14 days. Wound symptom score was performed before and after treatment. The levels of TNF-α, IL-6 and IL-8 were determined by ELISA. The wound healing time was observed and the wound healing rate was calculated. Adverse reactions were recorded and clinical efficacy was evaluated.Results:The total effective rate was 93.33% (42/45) in the observation group and 66.67% (30/45) in the control group, with statistical significance ( χ2=9.89, P=0.002). After treatment, the scores of pain [(0.63±0.14) vs. (0.97±0.27), t=7.50], exudation [(0.67±0.12) vs. (1.09±0.31), t=8.48], edema [(0.78±0.17) vs.(1.25±0.36), t=7.92], pruritus [(0.78±0.20) vs. (1.32±0.33), t=9.39] were lower than those in the control group ( P<0.01); serum TNF-α [(33.46±2.86) μg/L vs. (45.78±3.92) μg/L, t=25.39], IL-6 [(41.86±5.84) μg/L vs. (56.12±6.75) μg/L, t=15.98], IL-8 [(27.40±3.58) ng/L vs. (36.16±3.84) ng/L, t=16.69] were lower than those in the control group ( P<0.01). The wound healing time of the observation group was shorter than that of the control group ( t=8.60, P<0.01), and the wound healing rate was higher than that of the control group ( t=24.65, P<0.01). During treatment, the incidence of adverse reactions was 11.11% (5/45) in the observation group and 6.67% (3/45) in the control group, without statistical significance ( χ2=0.14, P=0.711). Conclusion:Neibu Huangqi Decoction combined with Kangfuxin Liquid can promote wound healing, reduce inflammatory cytokines, relieve pain and exudation, improve clinical efficacy, and have few adverse reactions.

Objective: To observe the efficacy of mild moxibustion combined with arthroscopic meniscal repair in the treatment of meniscal injury and to explore its action mechanism. Methods: Ninety-eight patients with meniscal injury were divided into a surgery group and a moxibustion plus surgery group by the random number table method, with 49 cases in each group. Both groups received arthroscopic meniscal repair, and the moxibustion plus surgery group was treated with add-on mild moxibustion. The Lysholm score, visual analog scale (VAS) score, and mobility of the affected knee were measured before and after treatment, and transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF) levels were measured in the fluid of the affected knee joint. The healing of the meniscus was recorded at a follow-up visit 3 months after the surgery. Results: After treatment, the Lysholm score increased, the VAS score decreased in both groups, and the intra-group differences in both groups were statistically significant (P<0.05). The Lysholm score was higher in the moxibustion plus surgery group than in the surgery group, and the VAS score was lower in the moxibustion plus surgery group than in the surgery group. The differences between groups in both scores were statistically significant (P<0.05). The mobility of the affected knee joint increased in both groups (P<0.05), and it was greater in the moxibustion plus surgery group than in the surgery group (P<0.05). When compared with pretreatment, the levels of TGF-β1 and PDGF in the fluid of the knee joint increased in both groups (P<0.05), and the levels of TGF-β1 and PDGF in the fluid of the affected knee joint were higher in the moxibustion plus surgery group than in the surgery group (P<0.05). The healing of the meniscus in the moxibustion plus surgery group was significantly better than that in the surgery group at the follow-up visit 3 months after the surgery (P<0.05). Conclusion: The effect of mild moxibustion combined with arthroscopic meniscal repair is better than the surgery alone in improving knee function, relieving pain, increasing mobility of the affected knee, and promoting meniscal healing, which may be related to the up-regulation of TGF-β1 and PDGF levels in the fluid of knee joint.

Recently, ferroptosis, an iron-dependent novel type of cell death, has been characterized as an excessive accumulation of lipid peroxides and reactive oxygen species. Emerging studies demonstrate that ferroptosis not only plays an important role in the pathogenesis and progression of chronic diseases, but also functions differently in the different disease context. Notably, it is shown that activation of ferroptosis could potently inhibit tumor growth and increase sensitivity to chemotherapy and immunotherapy in various cancer settings. As a result, the development of more efficacious ferroptosis agonists remains the mainstay of ferroptosis-targeting strategy for cancer therapeutics. By contrast, in non-cancerous chronic diseases, including cardiovascular & cerebrovascular diseases and neurodegenerative diseases, ferroptosis functions as a risk factor to promote these diseases progression through triggering or accelerating tissue injury. As a matter of fact, blocking ferroptosis has been demonstrated to effectively prevent ischemia-reperfusion heart disease in preclinical animal models. Therefore, it is a promising field to develope potent ferroptosis inhibitors for preventing and treating cardiovascular & cerebrovascular diseases and neurodegenerative diseases. In this article, we summarize the most recent progress on ferroptosis in chronic diseases, and draw attention to the possible clinical impact of this recently emerged ferroptosis modalities.

Objective:To analyze the dosage distribution and the frequency of each dosage of high-risk tablets in the hospitalized patients in a children's hospital,and study whether the existing specifications of high-risk tablets meet the pediatrics clinical needs. Methods:All the prescriptions including high risk tablets were analyzed from 2014 to 2016 in Shanghai children's medical center. The frequency of every dosage of every drug was analyzed,and the current specifications were judged according to the frequency. New specifications were proposed when the existing specifications did not match the clinical needs. The new frequency of the proposed speci-fications was re-accounted for all the three-year prescriptions in order to evaluate whether the proposed new specifications met the clini-cal needs. Results:Among the five kinds of high-risk oral tablets,methotrexate tablets and vitamin A acid tablets were in accordance with the actual clinical requirements. Mercaptopurine tablets should add two specifications including 12.5 mg and 17 mg,and warfarin sodium tablets should add one specification(1.25 mg). Hydroxyurea tablets(250 mg) and warfarin sodium tablets(1 mg) were rec-ommended used in the children's hospital. Conclusion:The existing specifications of high-risk oral tablets can't fully meet the clini-cal needs,therefore,specifications still needs to be adjusted.

Objective:To analyze the safety of generics and lactation of commonly used drugs in outpatient and emergency department of a children's hospital in Shanghai to formulate the related high-risk medicines list. Methods:According to the drug directory for outpatient and emergency department in the sample hospital,the medication assistant software was used to check the safety level of the related drugs used during pregnancy and lactation. Drugs with pregnancy safety grade D or X,and the lactation safety grade L4 or L5 involved in the high-risk pregnancy or breast-feeding drug list. Results:Of the 151 kinds of infusion medicines commonly used in outpatient and emergency department in the sample hospital, a total of 118 kinds were with a specified level of pregnancy safety,which accounted for 78.15%,and a total of 86 kinds were with a clear indication of the safety level of lactation,which accounted for 56.95% of the total number of medicines. A total of 25 kinds of drugs labeled pregnancy safety grade D or X, which accounted for 16.56%, and 21 species were with lactation safety L4 or L5, which accounted for 13.90% of the total number of drugs. The drugs with high pregnancy or lactation risk in the outpatient and emergency department of the sample children's hospital were anti-tumor drugs,anti-infective drugs,some cardiovascular drugs and central nervous system drugs. Conclusion:There are still many deficiencies in the information about the safety of pregnancy or breast-feeding in the existing medicines used in the sample hospital,which need to be improved.

Objective To systematically evaluate the incidences of complications of high frequency oscillatory ventilation ( HFOV) and conventional mechanical ventilation ( CMV ) in premature infants. Method Randomized controlled trials of HFOV and CMV in premature infants published in databases including PubMed, Embase, Cochrane Library, CNKI Database, Wanfang Database, Weipu Chinese Sci－Tech Periodical Database were searched.The retrieval time was from the establishment of the databases to January 2018.The quality of the literature were evaluated , and Stata 15.0 statistical software was used for meta－analysis.Result A total of 18 articles and 3 888 premature infants were included in the study , including 1 910 in the HFOV group and 1 978 in the CMV group.No significant differences were found in the incidences of in－hospital mortality, air leakage syndromes , retinopathy of prematurity (ROP),≥grade 3 intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), necrotizing enterocolitis (NEC) and patent ductus arteriosus ( PDA) requiring medication or surgery ( P ＞0.05 ).The incidences of bronchopulmonary dysplasia (BPD) (RR ＝0.90,95%CI 0.83 ～0.98),≥grade 2 ROP (RR ＝0.78, 95%CI 0.63～0.96) and pulmonary hemorrhage (RR＝0.63, 95%CI 0.47～0.85) in HFOV group was significantly lower than the CMV group (P＜0.05).In the subgroup analysis, the results of the researches in 1980s, 1990s, 2000s, and 2010s showed that no significant differences existed in in－hospital mortality between the HFOV group and the CMV group on ventilator pressure control mode and volume control mode (P＞0.05).Conclusion Current evidences suggested that comparing with CMV , the application of HFOV in preterm infants might reduce the incidences of BPD ,≥grade 2 ROP and pulmonary hemorrhage.

Objective: To study the correlation between the empty bottle volume, negative pressure and gas production of the freeze-dried powder in the out-patient pharmacy intravenous admixture center of a children' s hospital in order to provide reference for the drug production. Methods:20 ml Syringes were used to measure the volume of empty bottles, negative pressure and produced gas. The relationship between the theoretical drug dissolution volume and the actual dissolution volume was compared, and the precautions for the drug production were put forward. Results:Among the tested 30 drugs, 6 ones were with the actual dissolution volume half of the theoretical dissolution volume, 8 ones were with negative pressure in the bottles, and 3 ones were with produced gas after dissol-ving. It was appropriate that the empty bottle volume be 4 ml larger than the theoretical dissolution volume, and it was appropriate that the negative pressure volume of drugs was slightly larger than the theoretical dissolution volume. Negative pressure should be still kept in the bottles after the gas production. Conclusion:The design of part of freeze-dried powder injection needle shows defects resulting in drug mixing difficulties to a certain extent.
