OBJECTIVE: Clinical characteristics and outcome in COVID-19 with brucellosis patients has not been well demonstrated, we tried to analyze clinical outcome in local and literature COVID-19 cases with brucellosis before and after recovery. METHODS: We retrospectively collected hospitalization data of comorbid patients and prospectively followed up after discharge in Heilongjiang Infectious Disease Hospital from January 15, 2020 to April 29, 2022. Demographics, epidemiological, clinical symptoms, radiological and laboratory data, treatment medicines and outcomes, and follow up were analyzed, and findings of a systematic review were demonstrated. RESULTS: A total of four COVID-19 with brucellosis patients were included. One patient had active brucellosis before covid and 3 patients had nonactive brucellosis before brucellosis. The median age was 54.5 years, and all were males (100.0%). Two cases (50.0%) were moderate, and one was mild and asymptomatic, respectively. Three cases (75.0%) had at least one comorbidity (brucellosis excluded). All 4 patients were found in COVID-19 nucleic acid screening. Case C and D had only headache and fever on admission, respectively. Four cases were treated with Traditional Chinese medicine, western medicines for three cases, no adverse reaction occurred during hospitalization. All patients were cured and discharged. Moreover, one case (25.0%) had still active brucellosis without re-positive COVID-19, and other three cases (75.0%) have no symptoms of discomfort except one case fell fatigue and anxious during the follow-up period after recovery. Conducting the literature review, two similar cases have been reported in two case reports, and were both recovered, whereas, no data of follow up after recovery. CONCLUSION These cases indicate that COVID-19 patients with brucellosis had favorable outcome before and after recovery. More clinical studies should be conducted to confirm our findings.

OBJECTIVE: To investigate the effects of matrine combined with LY294002 on proliferation, apoptosis and cell cycle of human myeloid leukemia K562 cells and explore the underlying mechanism. METHODS: The effects of different concentrations of matrine alone and in combination with LY294002 on the proliferation of K562 cells were examined with CCK-8 assay. The changes in morphology of K562 cells were observed following treatment for 48 h with 0.4 g/L matrine and 10 μmol/L Y294002, either alone or in combination, and cell apoptosis was detected using flow cytometry with annexin V-FITC/PI double labeling; the changes in cell cycle was detected with PI labeling. Western blotting was performed to examine the effect of matrine combined with LY294002 on expressions of p-mTOR, p-PI3K, Akt, p-Akt, cyclinD1, Bcl-2 and caspase-9 in the cells. RESULTS: Treatment with different concentrations of matrine, both alone and in combination with LY294002, inhibited the proliferation of K562 cells in a time- and concentration-dependent manner. Compared with matrine treatment alone, the combined treatment caused more obvious morphological changes of the cells, significantly increased cell apoptosis (P < 0.01), and induced cell cycle arrest in G₀/G₁ (P < 0.01). Western blotting showed that the protein expression levels of p-mTOR, cyclinD1, p-PI3K, p-Akt and Bcl-2 in K562 cells increased while the expression level of caspase-9 decreased significantly after the combined treatment (P < 0.01). CONCLUSION Matrine combined with LY294002 produces a synergistic inhibitory effect on K562 cells possibly by down-regulating the p-Akt expression in PI3K/Akt signaling pathway, reducing the expressions of p-mTOR, cyclinD1 and Bcl-2, and increasing the expression of caspase-9.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Due to its own internal laws of development, Chinese medicine (CM) seems more inclined to empirical medicine in a relatively long historical period. It is considered to be lacking objective and unified clinical practice guidelines (CPGs), and the difficulties in diagnosis and therapeutic effect evaluation comes with it, have restricted its further inheritance, development and international communication. Over the years, our research group has been committed to improving the standardization theory and methodology of CM, also perfecting relative techniques for further application, which are all based on the stratified evidence scoring method. We have already applied this method to 45 issued guidelines, including 5 national guidelines, 3 industrial guidelines, and 37 formulation/revision social organization guidelines. The stratified evidence scoring method has been recognized and used widely. It helps scholars and applicators to study, formulate, publish and popularize the acupuncture therapy clinical practice guidelines better, thus further promotes the development of acupuncture therapy.

OBJECTIVE: To investigate whether blood-brain barrier (BBB) served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points (HTWP) in traumatic brain injury (TBI) and the potential molecular signaling pathways. METHODS: Adult male Sprague-Dawley rats were assigned to the sham-operated (sham), TBI, and bloodletting puncture (bloodletting) groups (n=24 per group) using a randomized number table. The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days. The neurological function and cerebral edema were evaluated by modified neurological severity score (mNSS), cerebral water content, magnetic resonance imaging and hematoxylin and eosin staining. Cerebral blood flow was measured by laser speckles. The protein levels of aquaporin 4 (AQP4), matrix metalloproteinases 9 (MMP9) and mitogen-activated protein kinase pathway (MAPK) signaling were detected by immunofluorescence staining and Western blot. RESULTS: Compared with TBI group, bloodletting puncture improved neurological function at 24 and 48 h, alleviated cerebral edema at 48 h, and reduced the permeability of BBB induced by TBI (all P<0.05). The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture (P<0.05 or P<0.01). In addition, the extracellular signal-regulated kinase (ERK) and p38 signaling pathways were inhibited by bloodletting puncture (P<0.05). CONCLUSIONS Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways. Therefore, bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema.

OBJECTIVE: To identify the prominent molecular signaling in acupoints and explore their roles in initiating the analgesia effect of manual acupuncture (MA). METHOD: A three-step study was conducted, the experiment 1 was a genome-wide analysis of the tissue at acupoint Zusanli (ST 36), including 12 Wistar rats which were divided into control, control+MA1, and control+MA7 groups. In the experiment 2, the paw withdrawal latency (PWL), immunohistochemistry and Western blot analysis of phospho-nuclear factor kappa B (NFκB) p65 (p-p65), phospho-NFκB p50 (p-p50) at ST 36 were performed on rats of saline, saline+MA, and complete Freund's adjuvant (CFA)+MA groups (n=6). In experiment 3, 24 rats were divided into saline+DMSO, CFA+DMSO, CFA+DMSO+MA, and CFA+BAY 11-7082+MA groups, the PWL and immunofluorescence assay of NFκB p65 at ST 36 was conducted. RESULT: (1) The gene: inhibitor of NFκB (Nfkbia), interleukin-1β (Il1b), interleukin-6 (Il6), chemokine c-x-c motif ligand 1 (Cxcl1), monocyte chemoattractant protein-1 (MCP-1/Ccl2) expressions in the control+MA7 group were significantly increased (P<0.05 or P<0.01), and the expression of NFκB p65 (Rela), NFκB p50 (Nfkb1) were increased in the control+MA7 group (P<0.05). (2) CFA+MA groups showed increased PWL from day 1 to 7 (P<0.01 vs. CFA), and the Western blot results were consistent with immunohistochemistry, the expression of NFκB p-p65 and NFκB p-p50 were significantly increased in the MA-related groups compared with control and CFA groups (P<0.05). (3) Compared with the CFA+DMSO+MA group, the PWL of the CFA+ BAY 11-7082+MA group decreased significantly and continued until day 5 and 7 (P<0.05 and P<0.01, respectively), and the NFκB p65 expression of CFA+BAY 11-7082+MA was significantly reduced compared with CFA+DMSO+MA (P<0.01). CONCLUSION Local NFκB signaling cascade in acupoint caused by MA is an important step in initiating the analgesic effect, which would provide new evidence for the initiation of MA-effect and improve the understanding of the scientific basis of acupuncture analgesia.

Methods: From July 2016 to April 2018, 124 patients who were diagnosed as Hp positive by gastrointestinal urease test and 13C breath test at the First Affiliated Hospital of He'nan University were randomly divided into group A(63 cases) and group B(61 cases) according to the digital table.Group A received bismuth potassium citrate + standard triple therapy, treatment for 14 days.Group B was given Jinghua Weikang capsule+ standard triple therapy, treatment for 14 days.One month after treatment, the treatment effect of the two regimens was recorded. Results: The total effective rates of group A and group B after one course of treatment were 88.89%(56/63) and 93.44%(57/61), respectively, the difference was no statistically significant between the two groups(χ²=0.795, P=0.373). The Hp eradication rates of group A and group B were 84.13%(53/63) and 95.08%(58/61), respectively, the difference was statistically significant(χ²=3.963, P=0.047). The proportions of patients with improved symptoms within 7 days in group A and group B were 68.25%(43/63) and 83.61%(51/61), respectively, the difference was statistically significant(χ²=3.983, P=0.046). The incidences of adverse reactions in group A and group B were 14.29%(9/63) and 3.28%(2/61), respectively, the difference was statistically significant(χ²=4.645, P=0.031). Conclusion Compared with bismuth potassium citrate, Jinghua Weikang capsule has similar clinical effect after one course of treatment, higher Hp eradication rate, lower incidence of adverse reactions, faster symptom improvement, and the satisfaction and compliance of patients are higher.

Objective: To summarize the research status of the changes in local microenvironment of acupoints caused by acupuncture, provide theoretical guidance for the initiation mechanisms of local acupuncture effect at acupoints. Methods: Using acupuncture, acupoint as key words to search China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed and other databases, the representative articles were selected for review. Results: Acupuncture could excite afferent nerves, activate cells, and promote the release of chemical substances like neuropeptide, hormone, cytokines, etc. in the local site of acupoints. Besides, it may cause mechanical deformation of connective tissues, and change chemical ions as well as ion channels. Conclusion: The microenvironment changes around acupoints are crucial to acupuncture effect; the concept of 'acupoints network' can be used to objectively describe the local changes around the acupoints after acupuncture.
