ABSTRACT

OBJECTIVE@#To study the protective effect of forsythiaside B (FB) against cerebral oxidative stress injury induced by cerebral ischemia/reperfusion (I/R) in mice and explore the underlying mechanism.@*METHODS@#Ninety C57BL/6 mice were randomized into sham-operated group, middle cerebral artery occlusion (MCAO) model group, and low-, medium and highdose (10, 20, and 40 mg/kg, respectively) FB groups. The expression levels of MDA, ROS, PCO, 8-OHdG, SOD, GSTα4, CAT and GPx in the brain tissue of the mice were detected using commercial kits, and those of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 were detected with Western blotting. Compound C (CC), an AMPK inhibitor, was used to verify the role of the AMPK pathway in mediating the therapeutic effect of FB. In another 36 C57BL/6 mice randomized into 4 sham-operated group, MCAO model group, FB (40 mg/kg) treatment group, FB+CC (10 mg/kg) treatment group, TTC staining was used to examine the volume of cerebral infarcts, and the levels of ROS and SOD in the brain were detected; the changes in the protein expressions of AMPK, P-AMPK, DAF-16, FOXO3 and P-FOXO3 in the brain tissue were detected using Western blotting.@*RESULTS@#In mice with cerebral IR injury, treatment with FB significantly reduced the levels of ROS, MDA, PCO and 8-OHdG, increased the activities of antioxidant enzymes SOD, GSTα4, CAT and GPx, and enhanced phosphorylation of AMPK and FOXO3 and DAF-16 protein expression in the brain tissue (P < 0.01). Compared with FB treatment alone, the combined treatment with FB and CC significantly reduced phosphorylation of AMPK and FOXO3, lowered expression of DAF-16 and SOD activity, and increased cerebral infarction volume and ROS level in the brain tissue of the mice (P < 0.01).@*CONCLUSION@#FB inhibits oxidative stress injury caused by cerebral I/R in mice possibly by enhancing AMPK phosphorylation, promoting the downstream DAF-16 protein expression and FOXO3 phosphorylation, increasing the expression of antioxidant enzymes, and reducing ROS level in the brain tissue.

ABSTRACT

Objective:To analyze the correlation between gastric disharmony and daily eating behaviors in college students, and to provide intervention measures for improving gastric disharmony among college students.Methods:From April 10 to 30, 2021, 3 825 college students from five Chinese medicine colleges and universities in China were selected for this study using the multi-level sampling method. The information regarding college student's general situation, daily eating behavior, and stomach disharmony was collected by questionnaire.Results:A total of 3 700 valid questionnaires were collected, with an effective response rate of 96.73%. The average age was (20.0 ± 3.0) years, and 66.41% of college students included in this study were female. Students with different characteristics had different gastric disharmonies and eating behaviors, and gastric disharmony was correlated with eating behavior. Multivariate analysis results showed that snacking ( OR = 1.11, 95% CI: 1.02-1.21), partial eclipse ( OR = 1.12, 95% CI: 1.00-1.26), picky eaters ( OR = 1.23, 95% CI: 1.08-1.41), and supper ( OR = 1.19, 95% CI: 1.04-1.36) were positively correlated with gastric disharmony. Eating regular meals ( OR = 0.86, 95% CI: 0.79-0.94) and 80% fullness ( OR = 0.89, 95% CI: 0.81-0.98) were negatively correlated with gastric disharmony. Conclusion:Poor eating behaviors may be an important factor leading to gastric disharmony.

ABSTRACT

Chinese medicine self-assembly nano-strategies(CSAN) is to utilize the self-assembly property of Chinese medicine components, so that the Chinese medicine components can self-assemble to form structurally stable nano-preparations through non-covalent interactions. The formation of Chinese medicine self-assembly nano-preparations is often a synergistic result of a variety of non-covalent interactions, and many Chinese medicine monomers are susceptible to self-assembly due to their structural characteristics, and the phenomenon of self-assembly of Chinese medicine is also common in the decoction of single or compound Chinese medicine, which has attracted the attention of researchers. It is found that CSAN can improve the solubility and bioavailability of active components in Chinese medicine, which is of positive significance for the development and application of insoluble components of Chinese medicine. The self-assembly phenomenon of Chinese medicine decoction is closely related to the therapeutic efficacy, and the study of self-assembly phenomenon of Chinese medicine will bring a new perspective for the explanation of the mechanism of Chinese medicine decoction. At the same time, traditional Chinese medicine(TCM) has unique advantages in the field of anti-tumor. The application of CSAN in the field of oncology can not only exert the anti-tumor effect of the active components of Chinese medicine directly, but also act as a natural nano-carrier to carry chemotherapy drugs for combination chemotherapy, improve the targeting of drugs, enhance the anti-tumor efficacy, and reduce the side effects of chemotherapy, which has excellent anti-tumor potential. The preparation method of Chinese medicine self-assembly nano-preparations is simple, low cost, and has better safety than traditional nano-preparations, which is conducive to the promotion of the clinical transformation of nano-preparations, and also helps to provide new strategies and perspectives for promoting the modernization of TCM. Therefore, based on a large number of researches in this field in recent years, this paper reviewed the formation mechanism, different assembly forms, formation conditions and stability of Chinese medicine self-assembly nano-preparations by searching databases such as China national knowledge infrastructure(CNKI), PubMed, WanFang data and VIP, and summarized the application of CSAN in different tumor therapies, providing a reference for further research on CSAN.

ABSTRACT

Objective:To investigate the clinical efficacy and precautions of O-arm combined with navigation-assisted steotomy and hemivertebra resection for congenital cervicothoracic hemivertebra.Methods:From February 2016 to October 2020, the clinical data of 12 patients with cervicothoracic hemivertebra admitted in Henan Provincial People's Hospital were retrospectively analyzed, including 5 males and 7 females, aged 9.4±2.6 years (range, 4-15 years). Intraoperative neural monitoring system was used to ensure the safety of surgical correction process and O-arm navigation system assisted the implantation of pedicle screws,hemivertebra resection, and scoliosis deformity correction. Postoperative CT was used to evaluate the accuracy of screw placement, and routine preoperative and postoperative X-ray films of the full-length spine in standing position were taken to measure the coronal and sagittal Cobb angles. The correction rate of scoliosis and kyphosis, internal fixation, shoulder height difference and bone graft fusion were calculated at the final follow-up.Results:A total of 108 pedicle screws were inserted in 12 patients, and the screw placement accuracy rate was 96.3% (104/108). The follow-up time was 37.9±10.2 months (range, 24-61 months). The number of fused segments was 5.4±1.1 (range, 4-7). One week after surgery, the correction rate of Cobb angle was 78.5%±3.2% for scoliosis and 70.1%±5.4% for kyphosis. There were statistically significant differences in side and kyphosis Angle and Scoliosis Research Society (SRS)-22 score between preoperative and 1 week after surgery ( P<0.05). There was no significant difference between the operation and the last follow-up ( P>0.05). At the last follow-up, all the 12 patients achieved gradeⅠ fusion. SI was 2.4±0.8 cm before operation, 1.0±0.6 cm at 1 week after operation, and 0.7±0.5 cm at last follow-up, and the difference was statistically significant ( F=38.30, P<0.001). No pseudojoint formation, significant loss of correction Angle, or rupture of internal fixation relaxant occurred during the operation or during follow-up. Conclusion:O-arm combined with navigation-assisted steotomy and hemivertebra resection for the treatment of congenital cervicothoracic hemivertebra has the advantages of good orthopedic effect, reduced radiation exposure and fewer complications, and accurate pedicle screw implantation and hemivertebra resection.

ABSTRACT

@#Abstract: Objective To understand the clinical manifestations, symptoms, treatment and recovery of neonates infected with Omicron variant (BA.5.1.3) of SARS-CoV-2, and provide a certain reference for subsequent diagnosis and treatment of related diseases. Methods The clinical manifestations, epidemiology, auxiliary examinations, and treatment processes of the neonate aged 4-day-old who was community-acquired infection of variant BA.5.1.3 in Sanya was retrospectively analyzed. Results The neonate's mother was identified as a close contact with patients with coronavirus disease 2019 (COVID-19) one hour before delivery, and tested positive for nucleic acid within 24 hours after delivery. But her breast milk, amniotic fluid, placenta, and umbilical cord were not detected for nucleic acid test after delivery. The nucleic acid test of the neonate was negative within 24 hours after birth. Then he was transferred to the hotel for isolation. Before the transfer, the mother and baby stayed in the same room and ate breast milk but the mother did not wear any mask. The neonate didn't have nucleic acid test on the second and third days of his life, and the nucleic acid test of the neonate was positive on the fourth day, negative on the fifth day, and positive on the sixth day. Then he was transferred to the designated hospital of COVID-19 for treatment. The neonate had no cough, no fever, yellow skin, abdominal distension, general breast feeding, and good reaction. On admission, the laboratory examination showed that blood routine examination and electrolyte were normal, and the myocardial enzyme and liver and kidney functions were normal. The bilirubin was significantly increased (449.3 μmol/L). The nucleic acid test of the neonate was positive and his chest imaging results were normal. The treatment measures were mainly isolation, feeding, blue light fading, close monitoring of vital signs, and antiviral drugs were administered. Jaundice subsided and abdominal distension was relieved after 6 d of treatment, and the treatment process was smooth without complications. Conclusions The results suggest that the neonates are susceptible to Omicron variant BA.5.1.3 and prone to aggregation. The evidence of vertical transmission is insufficient and the clinical symptoms of neonates infected with Omicron variant BA.5.1.3 are mid, with no involvement of organ damage of the heart, liver, kidney, brain, and other organs.

ABSTRACT

OBJECTIVE@#To evaluate the implications of the prognostic nutrition index (PNI) in non-metastatic renal cell carcinoma (RCC) patients treated with surgery and to compare it with other hematological biomarkers, including neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and systemic immune inflammation index (SII).@*METHODS@#A cohort of 328 non-metastatic RCC patients who received surgical treatment between 2010 and 2012 at Peking University First Hospital was analyzed retrospectively. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cutoff values of the hematological biomarkers. The Youden index was maximum for PNI was value of 47.3. So we divided the patients into two groups (PNI≤ 47. 3 and >47. 3) for further analysis. Categorical variables [age, gender, body mass index (BMI), surgery type, histological subtype, necrosis, pathological T stage and tumor grade] were compared using the Chi-square test and Student' s t test. The association of the biomarkers with overall survival (OS) and disease-free survival (DFS) was analyzed using Kaplan-Meier methods with log-rank test, followed by multivariate Cox proportional hazards model.@*RESULTS@#According to the maximum Youden index of ROC curve, the best cut-off value of PNI is 47. 3. Low level of PNI was significantly associated with older age, lower BMI and higher tumor pathological T stage (P < 0.05). Kaplan-Meier univariate analysis showed that lower PNI was significantly correlated with poor OS and DFS (P < 0.05). In addition, older age, lower BMI, tumor necrosis, higher tumor pathological T stage and Fuhrman grade were significantly correlated with poor OS (P < 0.05). Cox multivariate analysis showed that among the four hematological indexes, only PNI was an independent factor significantly associated with OS, whether as a continuous variable (HR=0.9, 95%CI=0.828-0.978, P=0.013) or a classified variable (HR=2.397, 95%CI=1.061-5.418, P=0.036).@*CONCLUSION@#Low PNI was a significant predictor for advanced pathological T stage, decreased OS, or DFS in non-metastatic RCC patients treated with surgery. In addition, PNI was superior to the other hematological biomar-kers as a useful tool for predicting prognosis of RCC in our study. It should be externally validated in future research before the PNI can be used widely as a predictor of RCC patients undergoing nephrectomy.

ABSTRACT

Neonates born through meconium-stained amniotic fluid (MSAF) may develop complications including meconium aspiration syndrome, persistent pulmonary hypertension of newborn and death. The approach to the resuscitation of these neonates has significantly evolved for the past few decades. Initially, under direct visualization technique, neonates with MSAF were commonly suctioned below the vocal cords soon after delivery. Since 2015, Neonatal Resuscitation Program (NRP®) of the American Academy of Pediatrics has recommended against "routine" endotracheal suctioning of non-vigorous neonates with MSAF but favored immediate resuscitation with positive pressure ventilation via face-mask bagging. However, the China neonatal resuscitation 2021 guidelines continue to recommend routine endotracheal suctioning of non-vigorous neonates born with MSAF at birth. This review article discusses the differences and the rationales in the approach in the resuscitation of neonates with MSAF between Chinese and American NRP® guidelines over the past 60 years.

ABSTRACT

To introduce the clinical experience of professor SUN Shen-tian in treatment of Tourette's syndrome (TS) with acupuncture. TS is a psychosomatic disease and the core pathogenesis refers to blood deficiency producing internal wind. The disease is located in the heart and liver. Acupoints are selected according to the functional orientation of the cerebral cortex. The extrapyramidal system area is preferred for tic disorder, and the emotional area is for behavioral disorder. The treatment focuses on regulating the mind by multiple methods, including manual needling technique used the transcranial repeated acupuncture, and regulating the mind by taking multiple acupoints, Baihui (GV 20), Neiguan (PC 6), Shenmen (HT 7) and Dazhong (KI 4) are stimulated. For abdominal twitching and mental symptoms of TS children, the first and third abdominal areas are selected. The target symptoms (biao) are treated specially by local acupoints, the combination of the starting and ending acupoints of the affected meridian, or the acupoints of the meridians with same name. The modified chaihu longgu muli decoction and siwu decoction are prescribed to sooth liver, nourish blood and soothe wind. In association with the characteristics and target symptoms of TS, the sequential therapy is used with filiform needling, intradermal needling, Chinese herbal medication and psychotherapy.

ABSTRACT

The paper introduces GAO Wei-bin's clinical experience in acupuncture treatment for neurogenic bladder. In association with the etiology, the location and types of neurogenic bladder and in accordance with nerve anatomy and meridian differentiation, the acupoints are selected accurately in treatment. Four acupoint prescriptions are allocated. For frequent urination and urinary incontinence, the foot-motor-sensory area of scalp acupuncture, Shenshu (BL 23) and Huiyang (BL 35) are used. For all kinds of urine retention, especially the patients who are not suitable for acupuncture at the lumbar region, Zhongji (CV 3), Qugu (CV 2), Henggu (KI 11) and Dahe (KI 12) are selected. For all kinds of urine retention, Zhongliao (BL 33) and Ciliao (BL 32) are applicable. For the patients with both dysuria and urinary incontinence, Zhongliao (BL 33), Ciliao (BL 32) and Huiyang (BL 35) are chosen. In treatment of neurogenic bladder, both biao (root causes) and ben (primary symptoms) are considered, as well as the accompanying symptoms; and electroacupuncture is combined accordingly. During the delivery of acupuncture, the sites where the acupoints located are detected and palpated so as to rationally control the depth of needle insertion and the operation of reinforcing and reducing needling techniques.

ABSTRACT

OBJECTIVE@#To evaluate the clinical efficacy and safety of decitabine combined with modified CAG regimen (D-CAG regimen) in patients aged ≥70 years with newly diagnosed acute myeloid leukemia (AML).@*METHODS@#The clinical data of 59 AML patients (≥70 years old) who were newly diagnosed and treated in the Hematology Department of the First Affiliated Hospital of Nanjing Medical University from November 2010 to June 2021 were retrospectively analyzed.@*RESULTS@#Among the 59 AML patients, 28 were males and 31 were females, with a median age of 74 (70-86) years. The complete remission (CR) rate was 69.4% (34/49), and the median duration of CR was 10.7 (0.6-125.4) months after 2 courses of D-CAG treatment. According to the British Medical Research Council (MRC) classification, there was only one patient in the favorable-risk group, and the CR rate was 71.8% (28/39) in the intermediate-risk group, and 55.6% (5/9) in the adverse-risk group, respectively. There was no statistical difference in the CR rate between the intermediate-risk and adverse-risk group. Referring to ELN 2017 genetic risk classification, CR rate was 88.2% (15/17) in the favorable-risk group, 45.5% (5/11) in the intermediate-risk group, and 66.7% (14/21) in the adverse-risk group. There was no significant difference in CR rate between the favorable-risk and adverse-risk categories, but both were significantly higher than that in the intermediate-risk group (P <0.05). Next-generation sequencing (NGS) analysis showed that 11 gene mutations with a frequency of more than 10%, including TET2 mutation (35.6%), ASXL1 mutation (30.5%), NPM1 mutation (28.8%), FLT3-ITD mutation (27.1%), DNMT3A mutation (22.0%), IDH1 mutation (15.3%), CEBPA single mutation (13.6%), TP53 mutation (13.6%), IDH2 mutation (11.9%), RUNX1 mutation (11.9%), and NRAS mutation (10.2%). There were no statistical differences in mutation frequency of these 11 genes between CR group and non-CR group. Compared with normal karyotypes, patients with complex karyotypes were more likely to develop TP53 mutations (P <0.001), while FLT3-ITD and DNMT3A mutations were more likely to occur in patients with normal karyotypes (P =0.04, P =0.047). The median follow-up, overall survival (OS), and event-free survival (EFS) of all the patients was 11.7 (1.5-128.2) months, 12.3 (1.5-128.2) months, and 8.5 (1.5-128.2) months, respectively. The median OS and EFS of CR patients were 19.8 and 13.3 months, respectively, which were significantly longer than 6.4 and 5.7 months in patients experiencing treatment failure (P < 0.001, P =0.009). In regard to genes with mutation frequency >10%, there were no statistical differences in CR rate, median OS, and median EFS between mutated and wild-type patients by Chi-square test and survival analysis. Univariate analysis showed that age, hemoglobin, lactate dehydrogenase, cytogenetics and CR were factors affecting prognosis, while multivariate analysis showed that only CR failure was an independent adverse prognostic factor for OS. The major adverse reactions to D-CAG regimen were grade 3-4 myelosuppression, pulmonary infection, and fever (infection focus was not identified).@*CONCLUSION@#D-CAG regimen is safe and effective in the treatment of AML patients ≥70 years old, and can partially improve the prognosis of elderly and high-risk patients.

ABSTRACT

We explored the correlations between the color difference values [ΔL~*(lightness), Δa~*(red-green), Δb~*(yellow-blue)] and the content of four active components(including sesquiterpenoids and polyacetylenes) in the powder of Atractylodes lancea and A. chinensis, aiming to provide reference for the quality evaluation of Atractylodis Rhizoma and establish a qualitative model that can distinguish between A. lancea and A. chinensis based on the chromatic values. The tristimulus values(L~*, a~*, and b~*) of 23 batches of A. lancea and A. chinensis were measured by a color difference meter. The content of atractylenolide Ⅱ, β-eudesmol, atractylodin, and atractylone in the 23 batches of samples were measured by high performance liquid chromatography(HPLC). Principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA) were performed to establish the qualitative models for distinguishing between A. lancea and A. chinensis. SPSS was employed to analyze the correlations between the tristimulus values and the content of the four index components. The results showed that the established PCA and PLS-DA models can divide the A. lancea and A. chinensis samples into two regions, and the tristimulus values of A. lancea and A. chinensis were positively correlated with the content of β-eudesmol and atractylodin. Therefore, the PCA and PLS-DA models can successfully identify A. lancea and A. chinensis, and the appearance color can be used to quickly predict the internal quality of Atractylodis Rhizoma. This study provides a reference for the quality evaluation of Atractylodis Rhizoma and the modern research on the color of Chinese medicinal materials.

ABSTRACT

Preliminary research in our laboratory found that compound YZG-330 can reduce mouse body temperature, which could be blocked by adenosine A1 receptor (A1R) antagonist DPCPX. Based on the downstream signaling pathway of the A1R, the mechanism by which YZG-330 lowers body temperature was further studied. The pharmacodynamics of YZG-330 was evaluated by measuring the rectal temperature; expression of the transient receptor potential (TRP) ion channel, the P38 protein and its phosphorylated form in mouse hypothalamic homogenate were detected by Western blotting. A Ca2+ fluorescent probe, Fluo-3AM, was added to cells to detect the effect of YZG-330 on the Ca2+ content of mouse hypothalamic cells. YZG-330 dose-dependently reduced the body temperature in mice, and the selective P38 inhibitor SB-203580 (20 mg·kg-1, i.p.) significantly inhibited the hypothermic effect of YZG-330. A TRPM8 antagonist 2 (0.1 μg per mouse, i.c.v.) markedly attenuated the hypothermic effect of YZG-330 (0.25 or 1 mg·kg-1, i.p.). YZG-330 (2 mg·kg-1, i.p.) significantly increased the phosphorylation of P38, an effect that could be attenuated by the A1R antagonist DPCPX (5 mg·kg-1, i.g.) in mouse hypothalamus. In addition, YZG-330 also prominently enhanced the expression of TRPM8, which could be blocked by SB-203580; YZG-330 (0.1-10 μmol·L-1) increased intracellular Ca2+ concetration in mouse hypothalamic cells in a dose-dependent manner, and was inhibited by the A1R inhibitor DPCPX (0.5 and 1 μmol·L-1) and TRPM8 antagonist 2 (1 μmol·L-1). In conclusion, YZG-330 exerts its hypothermic effect by activating the A1R to promote the phosphorylation of P38 protein and thereby up-regulating the expression and activity of the TRPM8 ion channel, resulting in increased intracellular Ca2+ concentration to stimulate mouse hypothalamus cells to down-regulate body temperature. All animal experiments were approved by the Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences.

ABSTRACT

OBJECTIVE@#To investigate the effect of celastrol on the proliferation and apoptosis of human multiple myeloma (MM) cell lines, reveal the relationship between IRAK4/ERK/p38 signaling pathway and celastrol regulating the proliferation and apoptosis of H929 and ARP-1 cells, and explore whether celastrol combined with bortezomib has synergistic effect. @*METHODS@#CCK-8 method was used to detect the viability of MM cell lines H929 and ARP-1 treated by different concentrations of celastrol, bortezomib, and their combination, and the synergistic effect was determined by Kim's formula. The apoptosis rate of H929 cells and necrosis rate of ARP-1 were detected by Annexin V/PI method. The expression of key proteins and apoptosis proteins in IRAK4/ERK/p38 signaling pathway were detected by Western blot. @*RESULTS@#Celastrol could significantly inhibit the proliferation of H929 and ARP-1 cells (r=0.9018, r=0.9244) and induce apoptosis in a time-dependent manner. Compared with the control group, celastrol could significantly up-regulate the expression of PARP and cleaved caspase-3 while down-regulate the expression of p-IRAK4, p-ERK, and p-p38 in H929 and ARP-1 cells. Celastrol and bortezomib alone inhibited the proliferation of H929 and ARP-1 cells. Compared with celastrol and bortezomib alone, their combination had lower cell survival rate and higher apoptosis rate (P<0.05). @*CONCLUSION@#Celastrol can inhibit the proliferation and promote the apoptosis of H929 and ARP-1 cells, which may be related to inhibiting the phosphorylation of IRAK4 and blocking the activation of IRAK4/ERK/p38 signaling pathway. Celastrol combined with bortezomib has synergistic effect, which can more effectively inhibit the proliferation and induce apoptosis of H929 and ARP-1 cells.

ABSTRACT

OBJECTIVE@#To compare the clinical effect between head acupuncture combined with exercise therapy and conventional acupuncture for nonspecific low back pain.@*METHODS@#A total of 64 patients with nonspecific low back pain were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 2 cases dropped off). In the control group, conventional acupuncture was applied at Jiaji (EX-B 2) of L1 to L3, ashi point, Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3) and Weizhong (BL 40). The observation group was treated with head acupuncture combined with exercise therapy, head acupuncture was applied at foot-motor-sensory area on the healthy side and Cuanzhu (BL 2), Tongziliao (GB 1) on the affected side, and McKenzie therapy was performed during retention. The needles were retained for 40 min, once a day, continuous treatment for 6 days with the interval of 1 day, 14 days were required in the two groups. Before and after treatment, the pain visual analogue scale (VAS) score, Oswestry disability index (ODI) score and infrared thermography temperature of pain area in the low back were compared in the two groups.@*RESULTS@#Compared before treatment, the VAS and ODI scores after treatment were decreased in the two groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). Compared before treatment, the infrared thermography temperature of pain area in the low back after treatment was increased in the two groups (P<0.01), and that in the observation group was higher than the control group (P<0.01).@*CONCLUSION@#Head acupuncture combined with exercise therapy could relieve pain, improve dysfunction and increase the local temperature of pain area in patients with nonspecific low back pain, and its curative effect is better than conventional acupuncture.
