Parkinson’s disease （PD） is a common chronic neurodegenerative disease with movement disorders as the main clinical manifestation. The nuclear factor-erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway is closely associated with the occurrence and progression of PD. TCM flavonoid monomers （luteolin， rutin， etc.）， alkaloids （camptothecin， sinomenine， and alkaloids extracted from Uncaria rhynchophylla）， terpenes （tanshinone ⅡA， carvacrol， paeoniflorin）， phenols （ellagic acid， rosmarinic acid）， saponins （ginsenoside RK1）， and traditional Chinese medicine compounds （Wuzi yanzong pill and PD formula-2） can resist oxidative stress damage， inhibit inflammatory responses and abnormal aggregation of α-synuclein， and regulate neurotrophic factors by activating the Nrf2/HO-1 signaling pathway， thereby alleviating dopaminergic neuronal damage.

Depression is a mental disorder characterized by persistent low mood and belongs to the category of "stagnation syndrome" in traditional Chinese medicine （TCM）， with the characteristics of high prevalence， high disability rate， high suicide rate， and high recurrence rate. The pathogenesis of depression is extremely complex and involves factors such as genetics， psychology， and social environment. Currently， clinical antidepressant drugs such as tricyclic and tetracyclic antidepressants， and selective serotonin reuptake inhibitors， have slow onset of action and significant adverse effects with long-term application. Furthermore， clinical statistics show that about one-third of patients do not respond to these types of medications. Enhancing the effectiveness of depression treatment has become a major challenge in the medical field. TCM， based on the holistic view and treatment based on syndrome differentiation， has unique advantages in the prevention and treatment of depression， including stable therapeutic effects， low recurrence rate， minimal side effects， and good patient compliance. As one of the heat-clearing drugs， Gardeniae Fructus has the effects of clearing heat， purging fire， cooling blood， and relieving restlessness， which makes it effective in treating patients with "stagnation syndrome". Literature studies have found that active components of Gardeniae Fructus， such as geniposide， genipin， and crocin， as well as drug pairs such as Gardeniae Fructus-Chuanxiong Rhizoma， Gardeniae Fructus-Acanthopanacis Senticosi Radix et Rhizoma Seu Caulis， and Gardeniae Fructus-Lycii Fructus， and prescriptions such as Zhizichi Tang， Yuejuwan， Zhizi Houpotang， Danzhi Xiaoyaosan， and Jieyu Anshen Granules， have shown significant antidepressant effects. The mechanism of action may be related to regulating the hypothalamic-pituitary-adrenal （HPA） axis， modulating neurotransmitters such as serotonin （5-HT） and dopamine （DA）， increasing brain-derived neurotrophic factor （BDNF） in the hippocampus， enhancing neurogenesis in the hippocampus， and regulating the nuclear factor-kappa B （NF-κB） signaling pathway to inhibit neuroinflammation. This article summarized the research progress on the active components of Gardeniae Fructus， drug pairs， and Chinse medicinal prescriptions containing Gardeniae Fructus， providing references for further promoting the clinical application of Gardeniae Fructus and its prescriptions in the treatment of depression.

Objective: To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs) combined with autologous Meek microskin transplantation on patients with extensive burns. Methods: The prospective self-controlled study was conducted. From May 2019 to June 2022, 16 patients with extensive burns admitted to the 990^th Hospital of PLA Joint Logistics Support Force met the inclusion criteria, while 3 patients were excluded according to the exclusion criteria, and 13 patients were finally selected, including 10 males and 3 females, aged 24-61 (42±13) years. A total of 20 trial areas (40 wounds, with area of 10 cm×10 cm in each wound) were selected. Two adjacent wounds in each trial area were divided into hUCMSC+gel group applied with hyaluronic acid gel containing hUCMSCs and gel only group applied with hyaluronic acid gel only according to the random number table, with 20 wounds in each group. Afterwards the wounds in two groups were transplanted with autologous Meek microskin grafts with an extension ratio of 1∶6. In 2, 3, and 4 weeks post operation, the wound healing was observed, the wound healing rate was calculated, and the wound healing time was recorded. The specimen of wound secretion was collected for microorganism culture if there was purulent secretion on the wound post operation. In 3, 6, and 12 months post operation, the scar hyperplasia in wound was assessed using the Vancouver scar scale (VSS). In 3 months post operation, the wound tissue was collected for hematoxylin-eosin (HE) staining to observe the morphological changes and for immunohistochemical staining to observe the positive expressions of Ki67 and vimentin and to count the number of positive cells. Data were statistically analyzed with paired samples t test and Bonferronni correction. Results: In 2, 3, and 4 weeks post operation, the wound healing rates in hUCMSC+gel group were (80±11)%, (84±12)%, and (92±9)%, respectively, which were significantly higher than (67±18)%, (74±21)%, and (84±16)% in gel only group (with t values of 4.01, 3.52, and 3.66, respectively, P<0.05). The wound healing time in hUCMSC+gel group was (31±11) d, which was significantly shorter than (36±13) d in gel only group (t=-3.68, P<0.05). The microbiological culture of the postoperative wound secretion specimens from the adjacent wounds in 2 groups was identical, with negative results in 4 trial areas and positive results in 16 trial areas. In 3, 6, and 12 months post operation, the VSS scores of wounds in gel only group were 7.8±1.9, 6.7±2.1, and 5.4±1.6, which were significantly higher than 6.8±1.8, 5.6±1.6, and 4.0±1.4 in hUCMSC+gel group, respectively (with t values of -4.79, -4.37, and -5.47, respectively, P<0.05). In 3 months post operation, HE staining showed an increase in epidermal layer thickness and epidermal crest in wound in hUCMSC+gel group compared with those in gel only group, and immunohistochemical staining showed a significant increase in the number of Ki67 positive cells in wound in hUCMSC+gel group compared with those in gel only group (t=4.39, P<0.05), with no statistically significant difference in the number of vimentin positive cells in wound between the 2 groups (P>0.05). Conclusions: The application of hyaluronic acid gel containing hUCMSCs to the wound is simple to perform and is therefore a preferable route. Topical application of hUCMSCs can promote healing of the autologous Meek microskin grafted area in patients with extensive burns, shorten wound healing time, and alleviate scar hyperplasia. The above effects may be related to the increased epidermal thickness and epidermal crest, and active cell proliferation.

ObjectiveTo improve the current standard of Belladonnae Herba in the 2020 edition of Chinese Pharmacopoeia. MethodTaking hyoscyamine sulfate， atropine sulfate and scopoletin as reference substances， and ethyl acetate-methanol-concentrated ammonia（17∶4∶2）as developing solvent， thin layer chromatography （TLC） was applied in the qualitative identification of Belladonnae Herba. The moisture， total ash and ethanol-soluble extract of Belladonnae Herba were determined based on the general principles in the 2020 edition of Chinese Pharmacopoeia （volume Ⅳ）. The contents of hyoscyamine sulfate and scopolamine hydrobromide were analyzed by high performance liquid chromatography （HPLC） with mobile phase of acetonitrile-54 mmol·L^-1 phosphate buffer solution （14∶86）， flow rate of 1.0 mL·min^-1 and detection wavelength at 210 nm. ResultThe spots in the TLC were clear with good separation and specificity. Hyoscyamine sulfate and scopolamine hydrobromide showed a good linearity with peak area in the range of 0.024 7-0.789 6 g·L^-1 （r=0.999 9） and 0.003 9-0.124 0 g·L^-1 （r=0.999 9）， the average recoveries of these two ingredients were 100.29% （RSD 1.6%） and 99.04% （RSD 1.4%）， respectively. The limits for moisture， total ash in Belladonnae Herba should be less than 13.0% and the limit for the ethanol-soluble extract should be more than 10.0%. Due to the low content and wide variation of scopolamine hydrobromide， the content of hyoscyamine sulfate should not be less than 0.098%. ConclusionThe established method is simple， specific and reproducible， which can be used to improve the quality control standard of Belladonnae Herba.

Reverse prediction and molecular docking techniques were employed to evaluate the feasibility of reniformin A(RA) as an anti-tumor leading compound. Based on the reverse prediction, network pharmacology was used to construct a "disease-compound-target-pathway" network. Thirty-nine tumor-related targets of RA were predicted, which participated in the regulation of multiple cellular activities such as apoptosis, cell cycle, and tumor metastasis, and regulated estrogen signal transduction and inflammatory response. Discovery Studio 2020 was adopted for molecular docking and toxicity prediction(TOPKAT). As revealed by the results, the binding affinity of RA with the tumor-related targets ABL1, ESR1, SRC and BCL-XL was stronger than that of oridonin(OD), while its mutagenicity, rodent carcinogenesis, and oral LD_(50) in rats were all inferior to that of OD. Furthermore, in vitro experiments were performed to confirm the anti-tumor activity of RA, and the mechanism was preliminarily discussed. The results demonstrated that RA was superior to OD in cytotoxicity, inhibition of cell colony formation, and induction of apoptosis. RA, possessing potent anti-tumor activity, is expected to be a new anti-tumor leading compound.

Objective:To observe the effect of Sinisan on the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TrKB）， 5-hydroxytryptamine （5-HT）/5-HT1A receptor （5-HT1AR）， and hypothalamus-pituitary-adrenal （HPA） axis in depressed rats， and explore the antidepressant mechanism of Sinisan based on BDNF/TrKB， 5-HT/5-HT1AR， and HPA axis. Method:A total of 120 male Wistar rats were randomly divided into a normal group， a model group， a fluoxetine （0.01 g·kg^-1） group， and low- （1.25 g·kg^-1）， medium- （2.5 g·kg^-1）， and high-dose （5 g·kg^-1） Sinisan groups， with 20 rats in each group. The depression model was induced by isolation combined with chronic unpredictable mild stimulation（CUMS） in rats except for those in the normal group for 21 days. Rats were then treated correspondingly once a day for 21 days by gavage. Those in the normal group and the model group received an equal volume of normal saline. During the intervention， the model rats were stimulated continuously. The depressive state of CUMS model rats was evaluated by sucrose preference test and open field test. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of corticotropin-releasing hormone （CRH）， adrenocorticotropic hormone （ACTH）， and corticosterone （CORT） in the plasma and BDNF and 5-HT levels in the hippocampal homogenate. The mRNA expression of hippocampal TrKB， 5-HT1AR， glucocorticoid receptor （GR）， and mineralocorticoid receptor （MR） was detected by real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR）. The protein expression of hippocampal TrKB， 5-HT1AR， GR， and MR was detected by Western blot. The histomorphological changes of the hippocampus were observed by hematoxylin-eosin （HE） staining. Result:Compared with the normal group， the model group showed decreased sucrose preference rate （P<0.01）， reduced horizontal and vertical scores in the open field test （P<0.01）， increased plasma content of CRH， ACTH， and CORT （P<0.01）， declining content of BDNF and 5-HT in the hippocampus （P<0.01）， dwindled mRNA and protein expression levels of TrKB， 5-HT1AR， and GR （P<0.01）， elevated mRNA and protein expression of MR （P<0.01）， and damaged hippocampal neurons revealed by HE staining. Compared with the model group， the groups with drug intervention showed increased sucrose preference rate （P<0.01） and horizontal and vertical scores in the open field test （P<0.05， P<0.01）， decreased content of plasma CRH， ACTH， and CORT （P<0.05， P<0.01）， elevated content of hippocampal BDNF and 5-HT （P<0.05， P<0.01）， elevated mRNA and protein expression levels of hippocampal TrKB， 5-HT1AR， and GR （P<0.05， P<0.01）， reduced mRNA and protein expression levels of hippocampal MR （P<0.05， P<0.01）， and recovered hippocampal neurons as revealed by HE staining. Conclusion:Sinisan can exert a significant antidepressant effect by increasing hippocampal BDNF and 5-HT content， up-regulating TrKB， 5-HT1AR， and GR mRNA and protein expression， down-regulating MR mRNA and protein expression， inhibiting HPA axis hypertrophy， and enhancing the regeneration and repair of hippocampal neurons.
