Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels， but their effectiveness is limited. The mechanisms underlying its onset are complex， and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression， involving multiple pathways， including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 （TLR4/NLRP3）， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， brain-derived neurotrophic factor/tyrosine kinase receptor B （BDNF/TrkB）， cyclic AMP/protein kinase A/cAMP response element-binding protein （cAMP/PKA/CREB）， and others. Traditional Chinese medicine（TCM） is based on a holistic approach and the principle of treatment based on the differentiation of syndromes， regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems， involving liver Qi stagnation， heart spirit deficiency， kidney essence depletion， and spleen dysfunction. TCM compound treatments focus on soothing the liver， strengthening the spleen， calming the heart， and replenishing essence， with formulas such as Xiaoyaosan， Zishui Qinggan Yin， and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi， such as salidroside， ginsenoside Rb₁， astragaloside， and muscone. External TCM treatments， primarily acupuncture， aim to open the orifices and invigorate the spirit. Acupoints such as Baihui， Shenting， and Yintang are commonly used. Additionally， massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression， aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

Objective:To compare the efficacy of Kirschner wire fixation combined with Suture-Bridge technique and simple Kirschner wire fixation in the treatment of old lateral malleolar avulsion fractures under all-inside arthroscopy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 56 patients with old lateral malleolar avulsion fractures, admitted at Xuzhou Central Hospital from January 2018 to June 2022, including 32 males (32 feet) and 24 females (24 feet), aged 19-57 years [(35.2±11.1)years]. Twenty-five patients were treated with Kirschner wire fixation under all-inside arthroscopy (K-wire group), while the other 31 patients were treated with Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy (K-wire combined with suture group). The surgical time, incision healing at 2 weeks after surgery, and fracture healing rate at 6 months after surgery of the two groups were detected. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores, and foot and ankle ability measure (FAAM) scores [including activities of daily living (ADL) scores and sports function (S) scores] of the two groups were assessed before surgery, at 3, 6 months after surgery, and at the last follow-up. The anterior drawer test was performed at 3, 6 months after surgery and at the last follow-up. The time of return to sports after surgery and complication rates were also recorded.Results:All the patients were followed up for 12-18 months [(14.2±2.2)months]. The surgical time in the K-wire combined with suture group was (56.3±12.5)minutes, longer than (41.1±8.2)minutes in the K-wire group ( P<0.01). The incisions in both groups were healed by first intention at 2 weeks after surgery. In the K-wire combined with suture group, all the fractures were healed at 6 months after surgery (100%), while in the K-wire group 22 patients (88%) obtained fracture healing ( P<0.05). There were no statistically significant differences in the AOFAS ankle-hindfoot scores, FAAM-ADL scores, or FAAM-S scores between the two groups preoperatively ( P>0.05). At 3, 6 months after surgery, and at the last follow-up, the AOFAS ankle-hindfoot scores in the K-wire combined with suture group were (89.7±3.4)points, (92.8±2.8)points, and (94.9±3.3)points respectively, higher than (87.4±4.4)points, (90.4±4.1)points, and (92.5±4.6)points in the K-wire group ( P<0.05); the FAAM-ADL scores and the FAAM-S scores in the K-wire combined with suture group were (90.1±3.5)points, (91.5±2.9)points, (92.8±3.0)points and (91.4±5.4)points, (92.8±5.0)points, (94.4±4.8)points respectively, higher than (86.8±5.0)points, (88.7±3.8)points, (90.3±3.7)points and (88.0±5.3)points, (89.5±4.8)points, (91.5±5.2)points ( P<0.05 or 0.01). The AOFAS ankle-hindfoot scores, FAAM-ADL scores, and FAAM-S scores at all postoperative time points were higher than those preoperatively and increased with the passage of the follow-up time ( P<0.01). The results of the anterior drawer test at all postoperative time points in the two groups were negative. The time of return to sports after surgery in the K-wire combined with suture group was (9.2±1.3)weeks, shorter than (10.3±1.5)weeks in the K-wire group ( P<0.01). One patient (3.2%) in the K-wire combined with suture group and 3 patients (12.0%) in the K-wire group had Kirschner wire loosening and withdrawal ( P>0.05). Neither of the two groups developed complications such as nerve or tendon injuries. Conclusion:Compared with simple Kirschner wire fixation under all-inside arthroscopy, Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy achieves higher fracture healing rate, more obvious improvement in life quality and ankle function, as well as earlier return to sports in the treatment of old lateral malleolar avulsion fractures.

AIM To explore the clinical effects of Shuilu Erxian Pills combined with Modified Didang Decoction on patients with early and middle stage diabetic nephropathy.METHODS Eighty-three patients were randomly assigned into control group(42 cases)for 12-week administration of Irbesartan Tablets,and observation group(41 cases)for 12-week administration of Shuilu Erxian Pills,Modified Didang Decoction and Irbesartan Tablets.The changes in clinical effects,TCM syndrome scores,blood glucose indices(FBG,HbA1c),blood lipid indices(TC,TG),renal function indices(BUN,Scr,24 h UTP,eGFR),inflammatory factors(IL-1β,hs-CRP,IL-6,TNF-α,IL-18,TGF-β1),immune function indices(lymphocyte,neutrophil,CD8+,CD3+,CD4+,CD4+/CD8+)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the observation group displayed decreased TCM syndrome scores,blood glucose indices,blood lipid indices,BUN,Scr,24 h UTP,inflammatory factors,CD8+(P＜0.05),reduced lymphocyte,neutrophil(P＜0.05),and increased eGFR,CD3+,CD4+,CD4+/CD8+(P＜0.05),which were more obvious than those in the control group(except for HbA1c,TG,SCr,24 h UTP,lymphocyte,neutrophil)(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with early and middle stage diabetic nephropathy,Shuilu Erxian Pills combined with Modified Didang Decoction can safely and effectively improve clinical symptoms,whose mechanism may contribute to the reduction of inflammatory levels and improvement of immune functions.

This study aimed to explore the possible effect of Xixin Decoction(XXD) on the learning and memory ability of Alzheimer's disease(AD) model senescence-accelerated mouse-prone 8(SAMP8) and the related mechanism in enhancing neuroprotective effect and reducing neuroinflammation. Forty SAMP8 were randomly divided into a model group(10 mL·kg~(-1)·d~(-1)), a probiotics group(0.39 g·kg~(-1)·d~(-1)), a high-dose group of XXD granules(H-XXD, 5.07 g·kg~(-1)·d~(-1)), a medium-dose group of XXD granules(M-XXD, 2.535 g·kg~(-1)·d~(-1)), and a low-dose group of XXD granules(L-XXD, 1.267 5 g·kg~(-1)·d~(-1)). Eight senescence-accelerated mouse-resistant 1(SAMR1) of the same age and strain were assigned to the control group(10 mL·kg~(-1)·d~(-1)). After ten weeks of intragastric administration, the Morris water maze was used to test the changes in spatial learning and memory ability of mice after treatment. Meanwhile, immunofluorescence staining was used to detect the positive expression of receptor for advanced glycation end products(AGER), Toll-like receptor 1(TLR1), and Toll-like receptor 2(TLR2) in the hippocampal CA1 region of mice. Western blot was employed to test the protein expression levels of silencing information regulator 2 related enzyme 1(SIRT1), AGER, TLR1, and TLR2 in the hippocampus of mice. Enzyme linked immunosorbent assay(ELISA) was applied to assess the levels of Aβ_(1-42) in the hippocampus of mice and the levels of nuclear factor κB p65(NF-κB p65), NOD-like receptor protein 3(NLRP3), tumor necrosis factor-α(TNF-α), and interleukin-1β(IL-1β) in the serum and hippocampus of mice. Compared with the model group, XXD significantly improved the spatial learning and memory ability of SAMP8, increased the expression of neuroprotective factors in the hippocampus, decreased the levels of neuroinflammatory factors, and inhibited the expression of Aβ_(1-42). In particular, H-XXD significantly increased the expression of SIRT1 in the hippocampus of mice, reduced the expression levels of NF-κB p65, NLRP3, TNF-α, and IL-1β in the serum and hippocampus of mice, and decreased the expression of AGER, TLR1, and TLR2 in the hippocampus of mice(P<0.05 or P<0.01). XXD may improve the spatial learning and memory ability of AD model SAMP8 by enhancing the neuroprotective effect and inhibiting neuroinflammation.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

This study was aimed to observe the distribution of Mas-related G protein-coupled receptor A (MrgA) in cerebrospinal fluid (CSF)-contacting nucleus of normal rats and its expression in neuropathic pain, and to provide morphological evidence for CSF-contacting nucleus to participate in neuropathic pain. The model of neuropathic pain with chronic constriction injury (CCI) of the sciatic nerve was made in Sprague-Dawley rats. The thermal withdrawal latency (TWL) and mechanical withdrawal threshold (MWT) were measured. The expressions of MrgA in the CSF-contacting nucleus were examined by double labeling with immunofluorescent staining. The results showed that on the 5th, 7th, 10th and 14th days, the values of MWT and TWL in CCI group were all lower than those in sham group (P < 0.05). MrgA was found to be distributed in CSF-contacting nucleus of normal rats; and the expression was markedly up-regulated in rats at the peak of neuropathic pain. Our data suggest that CSF-contacting nucleus may participate in neuropathic pain through the MrgA-mediated signaling pathway.

Baimai is a complex of structure and function with the characteristics of wide distribution, complex structure, and multi-dimensional functions. Baimai, consisting of the channels in brain, the internal hidden channels connecting the viscera, and the external channels linking the limbs, governs the sensory, motor, and information transmission functions of human. According to Tibetan medicine, Baimai functions via "Long"(Qi) which moves in Baimai. "Long" is rough, light, cold, tiny, hard, and dynamic. The dysfunction of Baimai is manifested as numbness, swelling and pain, stiffness, atrophy, contracture, disability, hyperactivity, etc. The clinical manifestations of Baimai disease are facial paralysis, limb numbness, hemiplegia, contracture and rigidity, pain, opistho-tonos, paralysis, unconsciousness, head tremor, aphasia and tongue stiffness, and other abnormalities in facial consciousness, limb movement, and tactile sensation. Baimai Ointment for external use is used for the treatment of Baimai disease. It is mainly composed of medicinals which are spicy and bitter, warm, soft, mild, heavy, moist, and stable, and thus it is effective for the rough, light, cold, tiny, hard, and dynamic "Long" of Baimai disease. In clinical practice, it is mainly used for musculoskeletal diseases, such as osteoarthritis, scapulohumeral periarthritis, cervical spondylosis, low back pain, myofascitis, and tenosynovitis, nervous system diseases, such as paralysis and shoulder-hand syndrome, and limb stiffness caused by stroke, spastic cerebral palsy, trigeminal neuralgia, and facial neuritis, and limb motor and sensory dysfunction caused by trauma. According to the main symptoms of Baimai disease such as stiffness, rigidity, contraction, numbness, sensory disturbance and pain, clinicians should apply the Baimai Ointment via the inunction treatment of Tibetan medicine and in combination with Huo'ermai therapy and physiotherapy.

OBJECTIVE: To investigate the short-term clinical effect of lumbar nerve root canal injection under X-ray angiography in the treatment of sciatica. METHODS: The clincal data of 78 patients with sciatica underwent lumbar nerve root canal injection under X-ray angiography from December 2017 to February 2020 was retrospectively analyzed. Including 31 males and 47 females, aged from 22 to 88 years old with a median of 65 years. There were 55 cases of lumbar disc herniation and 23 cases of lumbar spinal stenosis, the course of disease ranged from 1 to 8 weeks with a median of 3 weeks. There were 71 cases of single segment disc herniation or stenosis, including L_3,4 of 5 cases, L_4,5 of 61 cases, L₅S₁ of 5 cases, and 7 cases of multisegment herniation or stenosis. The pain visual analogue scale (VAS) was recorded and Macnab was used to evaluate the clinical effect. RESULTS: All patients completed standardized treatment without serious adverse reactions. VAS were (3.21±0.76) scores immediately after treatment, (2.89±0.33) scores 1 hour after treatment, (1.80±0.27) scores 6 hours after treatment, (1.10±0.20) scores 24 hours after treatment, (2.53±0.35) scores 1 week after treatment and (4.27±0.36) scores 1 month after treatment. There were significant differences in VAS between before treatment(7.83±0.56) and each time period after treatment(P<0.05). According to Macnab low back pain evaluation standard, 42 cases were effective, 34 cases were markedly effective and 2 cases were ineffective within 24 hours after treatment, with an effective rate of 97.4%;38 cases were effective, 25 cases were markedly effective, 15 cases were ineffective within one week after treatment, the effective rate was 80.0%;32 cases were effective, 22 cases were markedly effective, 24 cases were ineffective within one month after treatment, the effective rate was 69.2%. CONCLUSION The short-term clinical effect of nerve root canal injection under X-ray radiography in the treatment of sciatica is good and it is an effective method to relieve sciatica.

Pulmonary hypertension(PH)is a chronic,progressive,high-mortality disease characterized by a continuous increase in pulmonary vascular pressure. All types of PH have the same characteristics,i.e.,the excessive proliferation,anti-apoptosis and inflammation of pulmonary artery endothelial cells and smooth muscle cells,which leads to progressive thickening of pulmonary small vessels,resulting in pulmonary vascular remodeling and increased pulmonary vascular resistance,ultimately leading to right ventricular hypertrophy,heart failure,and death. The drugs used to treat PH mainly include L-type calcium channel blockers,phosphodiesterase 5 inhibitors,guanosine cyclase activators,endothelin receptor antagonists,and synthetic prostacyclin and its analogues. These drugs reduce pulmonary artery pressure by relaxing pulmonary blood vessels but do not cure the patient,and their prognosis remains poor. Therefore,the development of drugs that can effectively improve or even reverse pulmonary vascular remodeling is the key to treating PH. In recent years,studies on pulmonary vascular remodeling mainly included(1)the synthesis of new small-molecule compounds;(2)the transformation of mature drugs,such as the use of drug combinations and dosage form transformation,etc.;(3)the pharmacodynamic evaluation of traditional Chinese medicines and derived compounds based on the theory of "lung distension";(4)research into monomers of traditional Chinese medicine; and(5)research into new targets.
