ABSTRACT

We report the induced labor of conjoined twins in the second trimester in a woman with a history of two previous cesarean sections, the last one of which was performed in 2017. This 25-year-old patient was found to have thoracolumbar conjoined fetuses with one heart and polyhydramnios through the routine ultrasound examination at 19 +5 gestational weeks and was admitted at 20 +1 gestational weeks. After a full assessment of the fetal and maternal condition through multidisciplinary consultation, it was determined to attempt a vaginal delivery as no absolute contraindication for induction of labor. The patient was given 300 mg mifepristone orally plus an amniotic cavity injection of 100 mg ethacridine lactate. Regular contractions occurred 28 hours after medication. The patient delivered a pair of dead female conjoined twins at 20 +6 gestational weeks following successful induction of labor, with an assisted vaginal breech delivery. There was no soft tissue damage in the birth canal, and the estimated blood loss was 150 ml. Pathological examination and autopsy showed thoracolumbar conjoined deformity twins with a common heart and liver. Adequate prenatal evaluation, a detailed understanding of the indications for induction of labor and vaginal delivery, closed monitoring during labor, and preparation for emergency cesarean section, are essential safety measures for induced labor of conjoined twins in women with a scarred uterus in the second trimester.

ABSTRACT

@#Objective    To evaluate the early and mid-term safety of transcatheter aortic valve replacement via transfemoral (TF), transapical (TAp) and transsubclavian (TSc) approaches by meta-analysis. Methods    We systematically searched the clinical comparative trials published from inception to June 2019 from PubMed, Web of Science, EMbase and The Cochrane Library, to evaluate the safety of transcatheter aortic valve replacement through TF, TAp or TSc approaches. The information of all-cause mortality at 30 days, 1 year, 2 years and the incidence of common complications at 30 days after operation (including pacemaker-dependent block, major vascular complications, severe bleeding events, acute renal injury and stroke) were exacted, and a meta-analysis was conducted by RevMan 5.3 software. Results    This study included 11 literatures, with a total of 7 833 patients, among whom 5 348 patients were treated by TF TAVR, 1 796 patients by TAp TAVR and 689 patients by TSc TAVR. The results of the meta-analysis were as follows: (1)  at 30 days after operation, the mortality of TF and TSc approaches were lower than that of the TAp approach (TF vs. TAp:OR=0.57, 95%CI 0.39-0.84, P=0.004; TSc vs. TAp: OR=4.12, 95%CI 1.93-8.79, P=0.000 3). There was no statistical difference between the TF and TSc approaches (TF vs. TSc: OR=0.98, 95%CI 0.38-2.51, P=0.97); at 1 year, there was no statistical difference in mortality among the three approaches (P>0.05); at 2 years, there was no statistical difference between TSc and TF or TAp approaches (TF vs. TSc: OR=1.21, 95%CI 0.95-1.54, P=0.13; TSc vs. TAp: OR=1.02, 95%CI 0.76-1.36, P=0.91). (2) The incidence of acute kidney injury after TF approach was lower than that of the TAp approach (OR=0.30, 95%CI 0.22-0.41, P<0.000 01). (3) There was no statistical difference in major vascular complications between TSc and TF or TAp approaches (TF vs. TSc: OR=0.75, 95%CI 0.38-1.49, P=0.41; TSc vs. TAp: OR=1.37, 95%CI 0.56-3.32, P=0.49). (4) There was no statistical difference in severe bleeding events between TF and TSc (OR=0.97, 95%CI 0.53-1.76, P=0.92). (5) There was no statistical difference in the incidence of postoperative stroke, pacemaker dependent block among the three approaches (P>0.05). Conclusion    TAp and TSc approaches are safe and effective. They are not only an alternative to TF approach, but also the first choice in some patients with poor condition of iliofemoral artery.

ABSTRACT

At present, the medical system vigorously promotes multidisciplinary diagnosis and treatment model(MDT), and the timing of liver surgery for synchronous colorectal cancer with liver metastasis(sCRLM) is the focus of expert discussion. The same sCRLM case in different hospital or the different experts is likely to be a different treatment. On the one hand, that reflects the individualized characteristics of MDT. But on the other hand, it also reflects the lack of objective evaluation tools in sCRLM. The purpose of this study is to review the commonly used scoring tools of sCRLM, and to discuss the controversies of simultaneous or staged surgery for liver metastases, so as to inspire the clinical practice in this field.

ABSTRACT

Objective To analyze the efficacy and biomechanical properties of locking proximal femoral plate (LPFP) and proximal femoral nail anti-rotation (PFNA) for treating intertrochanteric fracture in elderly patients. Methods One hundred and six elderly patients with intertrochanteric fracture of femur were randomly divided into LPFP group (53 cases) and PFNA group (53 cases). After treatment intervention, the operation time, intraoperative bleeding volume, weight-bearing time, fracture healing time and Harris hip function score of 9 months after operation in two groups were recorded. The complications after operation in two groups were analyzed. Ten elderly fresh femoral specimens were selected to prepare the model of intertrochanteric femoral fracture in the elderly. They were randomly divided into PFNA group and LPFP group with 5 models in each group. After treatment and intervention, axial compression test, destructive load test and torsional stiffness test were conducted by mechanical testing machine, and biomechanical properties were recorded. Results The average operation time, weight-bearing time and fracture healing time in PFNA group were shorter than those in LPFP group (P<0.05), and the average intraoperative bleeding volume in PFNA group was less than that in LPFP group (P<0.05), and the average Harris score was higher than that in LPFP group (P<0.05). The total incidence of postoperative complications in PFNA group and LPFP group was 7.56% and 18.87%, respectively, indicating a significant difference between the two groups (P<0.05). After intervention treatment, the average axial compression, damage load and torsional stiffness in PFNA group were higher than those in LPFP group (P<0.05). ConclusionsPFNA caused minimal trauma for treating intertrochanteric femoral fractures in the elderly. With its good biomechanical properties, PFNA could effectively promote fracture healing and hip function recovery, and significantly reduce the incidence of hip varus, screw loosening and cutting complications.

ABSTRACT

Objective:Quantitative analysis of anti-inflammatory synergistic pharmacodynamics mechanism of baicalin and wogonoside by medium efficiency principle. Method:inflammatory cell model was constructed by stimulating RAW264.7 cells by lipopolysaccharide (LPS) 100 μg·L-1 in vitro. The experiment was performed in the normal group, the model group, the andrographolide group (10 μmol·L-1), the baicalin group (2.06,4.13,8.25,16.5,33,66,132 μmol·L-1) and the wogonoside group (2.94,5.88,11.75,23.5,47,94,188 μmol·L-1) and the baicalin-wogonoside combination group [(2.06+2.94)(4.13+5.88)(8.25+11.75)(16.5+23.5)(33+47)(66+94)(132+188) μmol·L-1]. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the cell culture supernatants after drug intervention for 50 min and 4 h were detected by enzyme-linked immunosorbent assay (ELISA) method. The level of nitric oxide (NO) in the cell culture supernatant after drug intervention for 24 h were detected by Griess method. Western blot was used to detect the activation levels of phosphorylation of nuclear factor-κB p65(p-NF-κB p65) and inducible nitric oxide synthase(iNOS) in cells after drug intervention for 2 h and 12 h. The fa/fu-dose profile of each indicator was drawn to observe the increase or decrease of effect. Result:Compared with normal group, the expression of p-NF-кB p65, iNOS and cytokines including TNF-α, IL-6 and NO (P<0.05,P<0.01) in the model group were significantly up-regulated. Compared with the model group, each group at high doses could inhibit the phosphorylation of NF-кB p65 protein(P<0.05),the baicalin group and the combined group could down-regulate the expression of iNOS protein in a concentration-dependent manner(P<0.01) and the baicalin group had no obvious inhibitory effect. each administration group at high dose could significantly inhibit the production of NO(P<0.05),but each group had no inhibitory effect on IL-6 production. The baicalin group and the combined group could significantly Inhibit the production of TNF-α(P<0.05) and there was no significant difference between the baicalin group and the model group. At the experimental dose, the fa/fu-dose table showed that the fa/fu value of p-NF-кB p65 and IL-6 in the combined group was not greater than the baicalin group and the wogonoside group. The fa/fu value of iNOS, TNF-α and NO in the combined group is higher than the baicalin group and the wogonoside group. Conclusion:The baicalin and wogonoside have different effects on different targets in the NF-κB pathway. The wogonoside is the main pharmacological substance in this combination and the combination shows different degrees of synergy or antagonism effects on different targets.

ABSTRACT

Wutou-Gancao herb-pair is extensively used to attenuate the toxicity and enhance the efficacy of aconite. In this study, potential synergic mechanism of the herb pair was investigated by utilizing multiple ap-proaches. In silico and in vitro Caco-2 cell models were applied to study the potential binding mode of bioactive ingredients existing in liquorice with P-glycoprotein (P-gp), as well as the inhibition effects on P-gp. Additionally, anti-inflammatory activity of aconitine (AC) combined with active ingredients of liquorice, as well as pharmacokinetic patterns of AC after co-administration was investigated. Anti-inflammatory effect of AC (1 mg/kg) in rats was enhanced in combination with bioactive ingredients of liquorice (10 mg/kg). In the meanwhile, the exposure of AC in vivo was altered, in terms of Cmax and AUC. For instance, the Cmax and AUC were increased to 1.9 and 1.3 folds, respectively, when used in combination with liquiritigenin. The in silico study revealed the potential binding mode with outward facing conformation of P-gp. The resulting data obtained from transport of rhodamine-123 (Rh-123) across Caco-2 cell monolayer further indicated that the function of P-gp was inhibited by chemicals in liquorice. The synergic effect was therefore proposed to be attributed to inhibition of P-gp by liquorice since AC has been demonstrated to be the substrate of P-gp. The resuls revealed that potential synergic mechanism of Wutou-Gancao herb-pair by inhibiting function of key efflux transporter P-gp to enhance the exposure of AC in systematic circulation, and further the anti-inflammatory effect, which helps clarify the compatibility rationale of these two herbs.

ABSTRACT

OBJECTIVE@#To investigate the imaging characteristics of F-FDG positron emission computed tomography (F-FDG PET/CT) in multiple myeloma (MM) patients and to analyze its application value in MM and bone metastases.@*METHODS@#A retrospective analysis was made on MM patients (n=72) and bone metastases patients (n=50) admitted to Hainan Western Central Hospital from January 2017 to March 2019. All patients underwent F-FDG PET/CT examination. The distribution of lesions, bone destruction, maximum standardized uptake (SUV) and metabolic homogeneity were analyzed in both groups.@*RESULTS@#More than 80% of MM and bone metastases involved thoracic bone, spine and pelvis, followed by limbs. MM was more common in the lesions of thoracic bone and skull than those in bone metastases, the difference was statistically significant (P<0.05). The majority of MM patients presented osteolytic bone destruction (97.2%), mostly showing "insect-like phagocytic pattern", so the bone showed dilated changes, and osteogenic changes were rarely seen (2.8%). Osteolytic bone destruction accounted for 74.0% in patients with bone metastatic tumor, presenting "focal" appearance more often, and osteogenic changes accounted for 26.0%. Osteolytic bone destruction in patients with MM was significantly higher than that in patients with bone metastases(χ=14.757,P<0.05). The SUV of MM (4.25±2.16)was significantly lower than that of bone metastases (7.84±3.25) (t=6.830, P<0.05). Diffuse mild uptake of F-FDG was more common in patients with MM, and heterogeneous high uptake of F-FDG was more common in patients with bone metastasis, the difference was statistically significant (P<0.05).@*CONCLUSION@#F-FDG PET/CT examination is helpful to acquire the imaging features of bone structure and metabolic changes, and shows an important clinical value in the differential diagnosis of MM and bone metastases.

ABSTRACT

Objective@#Screen the pathogenic genes of a pedigree with clinical manifestation of familial dilated cardiomyopathy in Inner Mongolia.@*Methods@#A total of 3 patients with dilated cardiomyopathy and 20 family members from the same family were examined in Ordos Central Hospital in Inner Mongolia from October, 2003 to August, 2017. Data on medical history, physical examinations, electrocardiograms, and echocardiography were obtained. 5 ml peripheral blood was sampled for per person. Chip Capture Sequencing technology was used to capture all the exons and splice sites of the genes that associated with hereditary cardiomyopathy and hereditary arrhythmia. The mutations in these genes were detected by high-throughput sequencing. All suspected pathogenic loci identified by high-throughput sequencing were verified by Sanger sequencing used for mutation detection. One hundred and fifty gender, age and race matched healthy people were included as the control group.@*Results@#Pathogenic gene variations were detected in 3 symptomatic family members and 1 carrier from the pedigree. Five pathogenic gene variations were identified in the proband (Ⅱ1), a pSer236Gly and a pArg215Cys variation in the MYBPC3 gene, a pGln90Arg variation in the DSP gene, and pAsn2912Asp and pGlu2910Val variation in the DMD gene. One pathogenic variation was detected in Ⅲ3, which was a pArg215Cys variation in the MYBPC3 gene. Two pathogenic variations were detected in Ⅲ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. Two pathogenic variations were detected in the Ⅳ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. No gene variation loci were detected in the other family members and the control group.@*Conclusion@#MYBPC3 gene, DSP gene and DMD gene variations are present in the familial dilated cardiomyopathy pedigree from Inner Mongolia, and these variations may be related with familial dilated cardiomyopathy.

ABSTRACT

Objective To construct a three-dimensional finite element model to investigate the biomechanical mechanism of carotid blast injuries.Methods Based on the head and neck CT angiography data of a healthy male volunteer,the 3D geometric model was extracted by Mimics software.The 3D solid model was obtained by fitting the geometric model to the non-uniform rational B-splines (NURBS) by Geomagic Studio software.The mesh of blood vessels,blood and soft tissue was divided by HyperMesh software to obtain the three-dimensional finite element model of the carotid artery.The material parameters and boundary conditions were set,and the vessel wall rupture damage threshold was 1 MPa.The dynamic process of carotid injury caused by MK3A2 grenade explosion shock wave at the distance of 60,70 and 80 cm to the neck was simulated using the LS-DYNA,generating the shock waveform and peak overpressure.The stress cloud map was used to analyze the stress distribution and damage morphology,and the stress curve was used to analyze the mechanical changes.Results The peak values of shock wave overpressure were 0.45,0.63 and 0.96 MPa at the distance of 80,70 and 60 cm away from the explosion center,respectively.At 80 cm,the peak stress of vessel wall was 0.43 MPa,and the vessel wall was not ruptured;at 70 cm,the peak stress of anonyma was greater than 1 MPa,which resulted in small rupture;at 60 cm,the peak stress of both anonyma the ascending aorta were greater than 1 MPa,leading to obvious rupture.The root part of the common carotid artery,anonyma and the arch of the aorta were high stress concentration areas,manifested as high-prevalence areas of damage and rupture.Conclusions The finite element model of explosive carotid artery injury is successfully constructed,which can be used to analyze the mechanical response and damage mechanism of carotid blast injuries.The main cause of injury and rupture is that the sudden change of stress in the process of explosion shock reaches or exceeds the threshold of vascular wall injury.Carotid artery rupture will occur when the vessel wall stress peak is greater than 1 MPa at 60 and 70 cm away from the explosion center,providing references for the clinical treatment and injury prevention.

ABSTRACT

OBJECTIVE@#This study aimed to investigate the relationship between alkaline phosphatase (ALP) and common carotid intima media thickness (IMT), carotid plaque, and extracranial carotid artery stenosis (ECAS).@*METHODS@#A total of 3,237 participants aged ⪖ 40 years were recruited from Jidong community in 2013-2014. Participants were divided into five quintile groups based on their serum ALP levels. Carotid atherosclerosis was assessed using ultrasound. Abnormal IMT, carotid plaque, and ECAS were defined as IMT > 0.9 mm, IMT > 1.5 mm, and ⪖ 50% stenosis in at least one extracranial carotid artery, respectively.@*RESULTS@#Common carotid IMT values and the prevalence of carotid plaque increased across serum ALP quintiles. Higher ALP quintiles were correlated with an increased risk of abnormal IMT [fourth quintile: odds ratio (OR) 1.78, 95% confidence interval (CI) 1.13-2.82, P = 0.0135; fifth quintile: OR = 1.82, 95% CI: 1.15-2.87, P = 0.0110] and ECAS compared to the lowest quintile (fifth quintile: OR = 1.47, 95% CI: 1.09-1.97, P = 0.0106). The association between ALP and prevalence of carotid plaque became insignificant after adjustment for confounders.@*CONCLUSION@#Serum ALP levels were independently associated with abnormal common carotid IMT and ECAS. These conclusions need to be further corroborated in future prospective cohort studies.

ABSTRACT

Aconiti Radix is a commonly used traditional Chinese medicine( TCM) herb in clinic,with the effects in expelling wind and removing damness,warming menstruation and relieving pain. With a long medicinal history and high medicinal value,it was used for anemofrigid-damp arthralgia,arthralgia,cold hernia and anesthesia analgesia. Modern pharmacological studies have shown that Aconiti Radix has a good therapeutic effect on rheumatoid arthritis,neuropathic pain and hypertension. As a well-known toxic TCM herb,its main pharmacodynamic and toxic components are alkaloids,which can lead to neurotoxicity and cardiotoxicity while exerting anti-inflammatory,analgesic,anti-tumor and other pharmacodynamic effects. Therefore,it is often processed to reduce its toxicity or combined with Paeoniae Radix Alba and Stephaniae Tetrandrae Radix to achieve the purpose of reducing toxicity and increasing efficacy in clinic.In recent years,with the deepening of the study on the incompatibility of TCM represented by " eighteen incompatible herbs",there have been new findings about TCM incompatibility. It has been found complementary effect,rather than no obvious toxic and side effects after the combination with incompatible herbs of Aconiti Radix. To provide the basis for further study and clinical application of Aconiti Radix,this paper reviewed chemical components,pharmacological action,toxicity and compatibility of Aconiti Radix by consulting relevant literatures published in recent years at home and abroad. Meanwhile,this paper also described the relationship between chemical constituents,as well as anti-inflammatory,analgesic,anti-tumor and other pharmacological effects and toxicity.

There were 116 single-flavored drugs distributed throughout India (including introduction or cultivation) and medicinal; while 51 single-flavored drugs were only distributed in India; 21 single-flavored drugs were distributed and used in China; 10 single-flavored drugs have a distribution in China but have not been used; only one single-flavored drug had been used in China but had no distribution. Yunnan, Guangdong, Guangxi, Fujian were provinces (districs) where Ayurveda single-flavored drug was planted and used more frequently. Sri Lanka, Vietnam and Malaysia were countries where Ayurveda single-flavored drug was planted and used more frequently. The original plants of the 169 single-flavored drugs were derived from Euphorbiaceae and Dipterocarpaceae, Umbelliferae and Morus, etc. More roots and rhizomes were used. The types of commonly treatment diseases were digestive diseases, respiratory diseases, “symptoms, signs, and clinical and laboratory abnormalities, which cannot be classified elsewhere”, skin and subcutaneous tissue diseases, genitourinary system diseases, blood diseases, etc. The diseases with characteristic diagnosis and treatment were caused by imbalance of body wind, intermittent heat, imbalance of mucin and imbalances of three diseases. CONCLUSIONS: 169 single-flavored drugs in this paper are distributed in tropical and subtropical regions, and are often used to treat digestive diseases. This study can provide reference for the introduction and cultivation of Ayurveda single-flavored drug and for the development of new drug sources and new uses in China.

ABSTRACT

Objective@#To compare the results obtained from the computer-aided sperm analysis (CASA) systems of the two fully-automated commercial sperm quality analyzers, Hamilton-Thorn IVOS Ⅱ (IVOS Ⅱ) and Spanish Sperm Class Analyzer (SCA).@*METHODS@#A total of 99 semen samples were collected in the Center of Reproduction of Shenzhen Zhongshan Urology Hospital from September 2018 to October 2018 and, according to the sperm concentration, divided into groups A (50 ×10⁶/ml). IVOS Ⅱ, SCA and manual microscopy were used for the examination of each sample, followed by comparison of the sperm concentration, sperm motility and percentage of progressively motile sperm (PMS) obtained from IVOS Ⅱ and SCA.@*RESULTS@#The sperm concentrations derived from IVOS Ⅱ and SCA were significantly higher than that from manual microscopy in group A ([10.24 ± 4.60] and [10.20 ± 5.11] vs [8.45 ± 4.15] ×10⁶/ml, P 0.05) or C ([102.14 ± 45.97] and [109.48 ± 46.32] vs [104.74 ± 41.87] ×10⁶/ml, P > 0.05). Significant differences were not observed between IVOS Ⅱ and SCA in the percentage of PMS ([24.21 ± 14.62]% vs [23.92 ± 15.42]%, P > 0.05) or sperm motility ([37.48 ± 19.34]% vs [37.69 ± 16.61]%, P > 0.05) in group B, nor in group C (PMS: [30.80 ± 12.06]% vs [32.98 ± 16.10]%, P > 0.05; sperm motility: [44.50 ± 15.62]% vs [47.26 ± 17.46]%, P > 0.05). Both the percentage of PMS and sperm motility obtained from IVOS Ⅱ were remarkably lower than those derived from SCA in group A (PMS: [18.54 ± 12.96]% vs [22.90 ± 12.88]%, P < 0.05; sperm motility: [26.97 ± 14.05]% vs [34.90 ± 15.18]%, P < 0.05). IVOS Ⅱ and SCA both showed a high repeatability (CV <15%), and the former exhibited an even higher one than the latter, in detection of sperm concentration, sperm motility and the percentage of PMS.@*CONCLUSIONS@#IVOS Ⅱ and SCA both had a good consistency in the results of sperm concentration, motility and progressive motility, but showed a poor comparability with low-concentration semen samples.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of autophagy activator (rapamycin, RAPA) and autophagy inhibitor (hydroxychloroquine, HCQ and 3-methyl adenine, 3-MA) on the proliferation, apoptosis and autophagy of multiple myeloma cell line of RPMI8226.</p><p><b>METHODS</b>RPMI8226 cells were treated with autophagy regulating drugs of different concentrations. The proliferation and apoptosis of cells were determined by CCK-8 and flow cytometry, respectively. The expressions of apoptosis-related proteins BCL-2, caspase-3 and PARP protein were assessed by Western blot. Autophagy was detected by monodansylcadaverine staining. Autophagic protein (LC-3b) and apoptosis-related proteins (caspase-3, PARP and BCL-2) were analyzed by Western blot.</p><p><b>RESULTS</b>RAPA and HCQ inhibited the proliferation of RPMI8226 in a concentration- and time-dependent manner, and increased the apoptosis. However, 3-MA did not show significantly inhibitory effect on the proliferation and apoptosis of RPMI8226. MDC staining showed that the more autophagic vacuoles could be detected in the higher concentration of RAPA, but the less autophagic vacuoles in the higher concentration of HCQ and 3-MA. Western blot showed that RAPA increased the expression of LC3-II/LC3-I, caspase-3 and PARP, but inhibited the expression of BCL-2. HCQ inhibited the expression of LC3-II/LC3-I and BCL-2, but increased the expression of caspase-3 and PARP. 3-MA inhibited the expression of LC3-II/LC3-I, but had no effect on the expression of caspase-3, PARP or BCL-2.</p><p><b>CONCLUSION</b>Rapamycin can inhibit the proliferation, induce apoptosis and autophagy of RPMI 8226, the hydroxychloroquine can inhibit autophagy and proliferation of RPMI 8226, and induce apoptosis, the 3-MA can inhibit autophagy of RPMI 8226, but hardly has any effects on proliferation and apoptosis of RPMI 8226 cells.</p>

ABSTRACT

Zha-xun is widely used in Tibetan medicine and is also an international traditional medicine. This article would summarize the use status and research progress of Zha-xun by various ethnic groups all over the world, and the results show that it has various synonyms but most of them imply its most characteristic feature-outflow from the rock; Zha-xun resources are distributed in various places of the world, and its bearing spots are closely related to the geological structure; there are sharp arguments on the origins of Zha-xun, mainly including the minerals origin, biological fossils origin, biological origin, etc. Zha-xun has multiple functions and is mainly used to treat stomach disease, liver disease and rheumatoid arthritis in China, and premature ejaculation, impotence, vaginitis embolism in foreign countries. "Iron" Zha-xun is used into medicines both at home and abroad. According to ancient materia medica texts, it was mainly classified into five types, including gold Zha-xun, silver Zha-xun, copper Zha-xun, iron Zha-xun and lead Zha-xun mainly based on the predominance of color rather than the minerals contained. It is commonly believed by the domestic and foreign scholars that humic acid is the main medicinal part of Zha-xun, and their studies have found that it has a variety of pharmacological activities such as anti-ulcer, anti-inflammatory, liver protection, analgesia, immune regulation, increasing sexual desire and fertility, antioxidation, antibacterial, antidiabetic, antiepileptic, antipsychotic, etc. This paper provides a scientific basis for the rational utilization of Zha-xun resources.
