ABSTRACT
Objective To investigate the clinical efficacy of Qiangli Pipa Syrup for the treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD),and to observe its effects on pulmonary function and interleukin 6(IL-6),C-reactive protein(CRP)and procalcitonin(PCT)levels in the patients.Methods Eighty patients with AECOPD of phlegm-heat obstructing the lung syndrome were randomly divided into the observation group and the control group,with 40 patients in each group.Patients in the control group were treated with conventional western medicine,and patients in the observation group were treated with Qiangli Pipa Syrup on the basis of treatment for the control group.Both groups were treated for 5 days.The two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores(including cough,expectoration,shortness of breath,and wheezing),pulmonary function parameters[the forced expiratory volume in one second(FEV1)and the ratio of FEV1 to the forced vital capacity(FVC)(FEV1/FVC)],blood gas indicators[arterial partial pressure of oxygen(PaO2),blood oxygen saturation(SaO2)and arterial partial pressure of carbon dioxide(PaCO2)]and the levels of the inflammatory factors of IL-6,CRP,and PCT before and after treatment.Moreover,the clinical efficacy and safety of the patients in the two groups were evaluated.Results(1)After 5 days of treatment,the total effective rate of the observation group was 95.00%(38/40),and that of the control group was 77.50%(31/40).The intergroup comparison(tested by chi-square test)showed that the therapeutic effect of the observation group was significantly superior to that of the control group(P<0.05).(2)After treatment,the TCM syndrome scores of cough,expectoration,shortness of breath,and wheezing in the two groups were reduced compared with those before treatment(P<0.05),and the reduction in the observation group was significantly superior to that in the control group(P<0.05).(3)After treatment,the pulmonary function parameters of FEV1/FVC and FEV1 in the two groups were improved compared with those before treatment(P<0.05),and the improvement in the observation group was significantly superior to that in the control group(P<0.05).(4)After treatment,the blood gas indicators of PaO2 and SaO2 levels in the two groups were increased compared with those before treatment(P<0.05),and the PaCO2 level was decreased compared with that before treatment(P<0.05).The increase of PaO2 and SaO2 levels and the decrease of PaCO2 level in the observation group were significantly superior to those in the control group(P<0.05).(5)After treatment,the serum levels of inflammatory factors of IL-6,CRP,and PCT in the two groups were lower than those before treatment(P<0.05),and the reduction in the observation group was significantly superior to that in the control group(P<0.05).(6)The incidence of adverse reactions in the observation group was 10.00%(4/40),while that in the control group was 7.50%(3/40).There was no significant difference between the two groups(P>0.05).Conclusion Qiangli Pipa Syrup exerts certain effect in treating patients with AECOPD of phlegm-heat obstructing the lung syndrome,which can effectively relieve the clinical symptoms,improve the pulmonary function and blood gas indicators,and inhibit inflammatory response of the patients,with high safety profile.
ABSTRACT
Objective:To investigate the survival rates of patients with liver cancer in Shanghai from 2002 to 2013. Methods:Data on new cases and deaths of liver cancer patients withfollow-up information from 2002 to 2013 were obtained from the Population-Based Cancer Registry and Vital Statistics System of the Shanghai Municipal Center for Disease Control and Prevention.Incidence and survival rates were stratified by year of diagnosis,gender,district,age-group and stage at diagnosis for analysis.Statistical indicators,such as case numbers,proportions,median age and mean age were calculated.The 1-to 5-year observed survival rates were calculated based on the life table method.The probabilities of surviving from 0 to 99 years old were estimated with the Elandt-Johnson model,and then cumulative expected survival rates were calculated using the Ederer Ⅱ method.Finally,the 1-to 5-year relative survival rates were calculated. Results:A total of 49 455 new cases of liver cancer were diagnosed from 2002 to 2013 in Shanghai,including 35 115 males and 14 340 females.The ratio of males to females was 2.45:1.The proportions of stage Ⅰ,stage Ⅳ and stage unknown were 3.32%,13.93%and 69.13%,respectively.The median survival time of patients with liver cancer diagnosed from 2002 to 2013 was 0.77 years,the 5-year observed survival rate was 13.23%,and the 5-year relative survival rate was 14.47%.According to the 5-year observed survival rate and 5-year relative survival rate of the cases,both survival indicators were higher in urban areas than in suburban areas,higher in males than in females,higher in cases under 45 years of age than in those over 75 years of age,higher in cases diagnosed from 2011 to 2013 than those diagnosed from 2002 to 2004.Additionally,the survival rate of cases decreased with increasing stage at diagnosis. Conclusion:With the continuous improvement of the diagnosis and treatment of liver cancer in Shanghai,the survival rate of patients with liver cancer has shown a significant upward trend over time.However,compared with various malignant tumors such as gastric cancer and breast cancer,the improvement effect of liver cancer survival rate is still not significant.Additionally,a high proportion of cases with unknown clinical stage at the time of diagnosis and a low survival rate of stage Ⅳ cases were observed.This study provides a basis for the prevention and research of liver cancer.
ABSTRACT
Objective To investigate the effect of plateau hypoxia on the blood-brain barrier after subarachnoid hemorrhage (SAH) in rats. Methods Adult male SD rats (n = 78) were randomly divided into 4 groups: sham group (sham), SAH model group (SAH), plateau hypoxia sham group (Hp sham) and plateau hypoxia SAH model group (Hp SAH). The rat model of plateau hypoxia was established through low-pressure simulation chamber (altitude 5000 m), and the SAH model was established by endovascular perforation method. At 24 hours after SAH, neurobehavior score and SAH grade were assessed. The morphological changes of neurons and apoptosis of nerve cells in the CA1 region of hippocampal were observed by the staining of Nissl and TUNEL. The expression of phosphorylated PI3K (p-PI3K), PI3K, phosphorylated Akt (p-Akt), Akt, phosphorylated nuclear factor κB (p-NF-κB), NF-κB, matrix metalloproteinase-9 (MMP-9), occludin and claudin-5 in hippocampal were detected by the method of Western blotting. The expression of occludin and claudin-5 proteins in the CA1 region of hippocampal were observed by immunofluorescent staining. Results At 24 hours after SAH, the neurobehavior score decreased significantly and SAH grade increased significantly in the SAH and Hp SAH group (P< 0.05). Neurobehavior score decreased significantly in the Hp SAH group compared with the SAH group (P < 0.05). In the SAH group, neurons in the CA1 region of hippocampus were atrophied and deformed, the arrangement were disordered, the number of neurons decreased significantly, and the apoptosis of nerve cells increased significantly(P< 0.05). Plateau hypoxia could aggravate the morphological damage of neurons and apoptosis of nerve cells. The expression of p-PI3K/PI3K, p-Akt/Akt, occludin and claudin-5 proteins decreased significantly, while the expression of p-NF-κB/NF-κB and MMP-9 proteins increased significantly in the SAH and Hp SAH group (P< 0.05). The expression of p-PI3K/PI3K and MMP-9 proteins increased significantly in Hp SAH group compared with the SAH group. The expression of claudin-5 protein increased significantly in Hp sham group compared with the sham group (P < 0.05). Immunofluorescent staining showed that the expression of occludin and claudin-5 proteins in the CA1 region of hippocampus decreased in the SAH group. Plateau hypoxia could further decreased the expression of occludin and claudin-5 proteins. Conclusion Plateau hypoxia aggravates blood-brain barrier disruption after subarachnoid hemorrhage in rats through inhibiting PI3K/Akt/NF-κB pathway.

In the era of artificial intelligence based on big data, data acquisition, storage and processing are more convenient, which provides a guarantee for accelerating the development of traditional Chinese medicine (TCM), but it has not yet achieved organic integration with TCM theory. Based on preliminary research on the supramolecular "Qi chromatography" theory of TCM, combined with the current development trend of artificial intelligence, this paper analyzed the biological intelligence attribute of the function of TCM supramolecular "imprinting template", in order to provide reference for the development of TCM drug innovation. Both the human body and Chinese materia medica are giant complex supramolecular bodies evolved from natural organisms. According to the "imprinting template", the "social molecules" are controlled step by step to form the meridians and viscera. The interaction produces the original theory of TCM, in which the self-recognition, self-assembly, self-organization and self-replication of the "imprinting template" reflect the "intelligence" function attributes:the human body uses the "imprinting template" to self-identify and sense the ingredients of TCM, and store the memory information database in the meridian and collateral organs in the form of "imprinting template", and then pass the "imprinting template". The comparison, analysis, and judgment of imprinting templates guide the self-assembly, self-organization and self-replication among "molecular society", synthesize biological machines, produce biological functions, repair or strengthen biological supramolecular bodies, and present the most basic "intelligence" attribute. This suggests that the theory of theory-method-prescription-medicine of TCM is the weak embodiment of biological "intelligence", while the human brain function is the strong embodiment of biological "intelligence". Since the intelligent function of supramolecular "imprinting template" runs through the natural world, artificial intelligence that can characterize the strong "intelligence" form of the human brain will also be integrated into all aspects of the natural world, suggesting the development direction of "intelligence" functionalization of drug innovation mode.
ABSTRACT
Gut microbiome sequencing studies have great potential to translate microbial analysis outcomes into human health research. Sequencing strategies of 16S amplicon and whole-metagenome shotgun (WMS) are two main methods in microbiome research with respective advantages. However, how sample heterogeneity, sequencers and library preparation protocols affect the sequencing reproducibility of gut microbiome needs further investigation. This study aims to provide a reference for the selection of sequencing technologies by comparing differences in microbial composition from different sampling sites. The results of three widely adopted sequencers showed that the technical repetition correlation (r= 0. 94) was high in WMS method, while the biological repetition correlation (r = 0. 69) was low. Bray-Curtis distance identified that dissimilarity from biological replicates was larger than that of technical replicates (P<0. 001). In addition, dissimilarity and specific taxonomic profiles were observed between 16S and WMS datasets. Our results imply that homogenization is a necessary step before sample DNA extraction. The sequencers contributed less to taxonomic variation than the library preparation protocols. We developed an empirical Bayes approach that " borrowed information" in calculations and analyzed batch effect parameters using standardized data and prior distributions of (non-) parameters, which may improve population comparability between 16S and WMS and provide a basis for further application to fusion analysis of published 16S and microbial datasets.
ABSTRACT
The application of modern scientific theories and technologies to explore the mechanism of Chinese medicine and its compounds is one of the key issues in realizing the modernization of traditional Chinese medicine (TCM) research. Chinese medicine and its compounds produce comprehensive pharmacodynamics through multiple components acting on multiple targets, the core of clarifying the mechanism is to solve the key scientific problems of static correlation and dynamic integration verification between the components and the target network topology. At present, the effective method to clarify the mechanism of Chinese medicine and its compounds is to statically correlate the topological network of in vitro components and targets through network pharmacology. Although there are also component-target verification studies, they often learn from research idea of single component-single target, it is urgent to establish a quantitative integration and overall verification method that conforms to the characteristics of TCM. According to supramolecular Qi chromatography theory of TCM, the microscopic mechanism of interaction between Chinese medicine and human body is actually the two supramolecular host and object groups (the active ingredient group of Chinese medicine and the target group of human body) based on imprinted template, which shows the macroscopic properties and pharmacodynamics. Based on this, the author proposes to use supramolecular Qi chromatography theory as the guidance, combined with supramolecular chemistry, network dynamics, quantitative pharmacology and other methods to quantitatively integrate and verify the compositions and the target groups with imprinted template as the core predicted by network pharmacology, looking for the optimal quality markers, greatly reducing the difficulty of multi-component-multi-target experimental verification of Chinese medicine and its compounds.
ABSTRACT
Objective:To construct the targeting evaluation method of traditional Chinese medicine (TCM) preparations based on supramolecular Qi chromatography theory, and to study the liver targeting effect of Bupleuri Radix on Pien Tze Huang. Method:The molecular connectivity index (MCI) was used to analyze the characteristics of imprinted template and liver targeting tendency of TCM mainly attributed to liver meridian and components of Pien Tze Huang, and combined with target dynamics and total statistical moment principle, aimed at the independent action characteristics of multi-component imprinted template of TCM, a method for evaluating the targeting of TCM preparations was established. Hepatoma rats in Pien Tze Huang group, Bupleuri Radix<italic> </italic>group, Pien Tze Huang+Bupleuri Radix group and blank group were tested and verified. Result:After the average value of MCI of TCM mainly attributed to liver meridian was deducted, the MCI similarity between Pien Tze Huang group and Bupleuri Radix group was 0.376 8, Pien Tze Huang+Bupleuri Radix group and Bupleuri Radix group was 0.988 2, so it was predicted that Bupleuri Radix could enhance the liver targeting of Pien Tze Huang. A system for evaluating the targeting of TCM compounds was established, including relative total uptake efficiency (RUE<sub>T</sub>), relative total concentration (RC<sub>T</sub>), relative imprinted tendency (RIT<sub>T</sub>) and relative imprinted variance (RIV<sub>T</sub>). The RUE<sub>T</sub> and RC<sub>T</sub> of liver were the highest in all tissues (RUE<sub>T</sub>=1.88>1,RC<sub>T</sub><italic>=</italic>2.30>1), and the corresponding values of other tissues were all <1, indicating that Pien Tze Huang combined with Bupleuri Radix could increase its distribution in liver and enhance liver targeting. Except for plasma, the RIT<sub>T</sub> and RIV<sub>T</sub> of other tissues fluctuated around 1.0, indicating that targeted modification did not change imprinted tendency of Pien Tze Huang and had no significant effect on the types of components. Conclusion:Under the guidance of supramolecular Qi chromatography theory, a targeting evaluation parameter system can be established to characterize the multi-component imprinted effect of TCM preparations by MCI and total statistical moment parameters, so as to realize the evaluation of targeting of TCM preparations. The addition of Bupleuri Radix can increase the liver targeting of Pien Tze Huang.
ABSTRACT
Objective:The molecular connectivity index method and total statistical moment method were used to control the quality of traditional Chinese medicine (TCM), and the stability and consistency of volatile components of Lonicerae Japonicae Flos and Lonicerae Flos were clarified. Method:Volatile oils in Lonicerae Japonicae Flos and Lonicerae Flos from different producing areas was extracted for GC-MS determination with electron bombardment ion source, ion source temperature of 230 ℃, and detection range of m/z 35-650. Then National Institute of Standards and Technology (NIST) 05 and ChemicalBook database were used for qualitative analysis of these volatile components, the peak area normalization method was used for quantitative analysis, and the total statistical moment parameters and the zero-order, first-order, second-order, third-order molecular connectivity indexes of the components were calculated. Result:Number of peaks (RSD were 28.5%, 33.4%, respectively), total zero-order moments (RSD were 55.5%, 128.9%, respectively) and total second-order moments (RSD were 15.3%, 21.5%, respectively) of 10 batches of Lonicerae Japonicae Flos and Lonicerae Flos were unstable, indicating that the types and contents of volatile components fluctuated sharply, but the total first-order moments (RSD were 7.5%, 8.8%, respectively) and the zero-order, first-order, second-order and third-order molecular connectivity indexes (RSD ranged from 8.1% to 10.3% and 4.2% to 5.5%, respectively) were relatively stable, indicating that the overall "imprinting template" of the components was similar. Statistical analysis of each parameter found that there were no significant differences in the number of peaks, total first-order moments and zero-order, first-order, second-order, third-order molecular connectivity indexes between volatile oils from Lonicerae Japonicae Flos and Lonicerae Flos. Conclusion:Under the guidance of supramolecular gas evolution "imprinting template" theory, the molecular connectivity index method and total statistical moment parameters are used to jointly characterize the "imprinting template" of TCM components in vitro, which can control the stability and consistency of TCM quality.
ABSTRACT
PURPOSE: To compare the effect of apixaban and low molecular weight heparin (LMWH) in the prevention and treatment of deep venous thrombosis (DVT) after total knee arthroplasty in older adult patients. MATERIALS AND METHODS: A total of 220 patients (average age of 67.8±6.4 years) undergoing total knee arthroplasty were randomly selected as research subjects and were divided into apixaban and LMWH groups (110 in each group). RESULTS: The incidence of DVT was lower in the apixaban group than in the LMWH group (5.5% vs. 20.0%, p=0.001). Activated partial thromboplastin times (35.2±3.6 sec vs. 33.7±2.2 sec, p=0.010; 37.8±4.6 sec vs. 34.1±3.2 sec, p<0.001; 39.6±5.1 sec vs. 35.7±3.0 sec, p=0.032) and prothrombin times (14.0±1.0 sec vs. 12.8±0.9 sec, p<0.001; 14.5±1.2 sec vs. 13.0±1.1 sec, p<0.001; 15.3±1.4 sec vs. 13.2±1.3 sec, p=0.009) in the apixaban group at 1 week after surgery, 3 weeks after surgery, and the end of treatment were higher than those in the LMWH group. Platelet and fibrinogen levels in the apixaban group were lower than those of the LMWH group. Also, capillary plasma viscosity and erythrocyte aggregation in the apixaban group at 1 week after surgery, 3 weeks after surgery, and the end of treatment were lower than those in the LMWH group. CONCLUSION: Apixaban, which elicits fewer adverse reactions and is safer than LMWH, exhibited better effects in the prevention and treatment of DVT after total knee arthroplasty in older adults.

To investigate the inhibitory effect of isobutyrylshikonin on the growth of human colon carcinoma cells and its effect on the PI3K/Akt/m-TOR pathway. MTT assay was used to detect the inhibitory effect of different concentrations (0, 6.25, 12.5, 25, 50, 100 mg·L⁻¹) of isobutyrylshikonin on the proliferation of human colon carcinoma cell HT29 at 24, 48 h. CCK-8 method was used to detect the inhibitory effect of isobutyrylshikonin on HT29, HCT116, DLD-1 and Caco-2 at 48 h. AnnexinV/propidium iodide staining was applied in detecting the apoptoticrate of HT29 cells treated with different concentrations of isobutyrylshikonin at 24 h and 48 h. Cycletest plus DNA was employed to analyze HT29 apoptosis and cell cycle after 48 h treatment with isobutyrylshikonin at different concentrations. Western blot and RT-PCR assay were used to examine the protein and mRNA expressions of PI3K, p-PI3K, Akt, p-Akt and m-TOR. The results showed that isobutyrylshikonin inhibited the proliferation of different human colon carcinoma cells, and the inhibition rate was in a dose-dependent manner. Isobutyrylshikonin induced apoptosis mainly in the early stage and blocked cells in the G₀/G₁ or G₂/M phase. Isobutyrylshikonin reduced the protein expressions of PI3K, p-PI3K, Akt, p-Akt, m-TOR and the mRNA expressions of PI3K, Akt, m-TOR in a dose-dependent manner. Isobutyrylshikonin can significantly inhibit the proliferation, induce the early apoptosis and change the cycle distribution in colon carcinoma cells.This biological effect may be correlated with the inhibition of PI3K/AKT/m-TOR pathway.
ABSTRACT
Objective To observe the clinical efficacy of Tiao Shen Jie Jing needling (regulating the mind and release spasm) in treating post-stroke upper-limb spastic palsy. Method Ninety patients with post-stroke upper-limb spastic palsy were randomized into an observation group and a control group, 45 cases each. The observation group was intervened by Tiao Shen Jie Jing needling, while the control group was given ordinary acupuncture. The Modified Ashworth Scale (MAS), short-form Fugl-Meyer Assessment (SFMA) and Barthel Index (BI) were evaluated and recorded prior to the treatment, after 2-week and 4-week treatment and 3 months later after the intervention; the serumγ-aminobutyric acid (GABA) was detected before and after the treatment. Result The total effective rate was 83.3% in the observation group versus 61.0% in the control group, and the efficacy of the observation group was superior to that of the control group (P<0.05). The scores of each scale showed improvements after the treatment in both groups (P<0.05), and the improvements in the observation group were more significant (P < 0.05). The follow-up showed continuing improvements in the scales in the observation group, which were superior to those in the control group (P<0.05); after the treatment, the content of GABA in the observation group was significantly higher than that in the control group (P<0.05). Conclusion Tiao Shen Jie Jing needling can effectively ameliorate the upper-limb spasm,as well as the motor function of the upper extremities, improve the activities of daily living and maintain a long-term efficacy, better than ordinary acupuncture. The action mechanism is related to the regulation of GABA content in serum.

Alkaloids from Ba lotus seeds (ABLS) are a kind of important functional compounds in lotus seeds. The present study was designed to determine its hypertension prophylactic effects in the L-NNA-induced mouse hypertension model. The mice were treated with ABLS, the serum and tissues levels of NO, MDA, ET-1, VEGF, and CGRP were determined using the experimental kits, the mRNA levels of various genes in the heart muscle and blood vessel tissues were further determined by RT-PCR assay. ABLS could reduce the systolic blood pressure (SBP), mean blood pressure (MBP), and diastolic blood pressure (DBP), compared to that of the model control group. After ABLS treatment, the NO (nitric oxide) contents in serum, heart, liver, kidney and stomach of the mice were higher than that of the control mice, but the MDA (malonaldehyde) contents were lower than that of the control mice. The serum levels of ET-1 (endothelin-1), VEGF (vascular endothelial growth factor) were decreased after ABLS treatment, but CGRP (calcium gene related peptide) level was increased. The ABLS treated mice had higher mRNA expressions of HO-1, nNOS, and eNOS and lower expressions of ADM, RAMP2, IL-1β, TNF-α, and iNOS than the control mice. Higher concentration of ABLS had greater prophylactic effects, which were close to that of the hypertension drug captopril. These results indicated the hypertension prophylactic effects of ABLS could be further explored as novel medicine or functional food in the future.

RESULTS AND CONCLUSION:Al the 19 patients were fol owed up for 13 months to 3 years, the leg and lumbar pain of al the patients were relieved to varying degrees. Preoperative VAS score was 7.3±1.28 points and postoperative VAS score was 2.1±0.8 points, showing significant difference between two groups (P<0.05). The excellent and good rate was up to 95%with 15 excellent results, 3 good results and 1 acceptable result depending on Macnab evaluation standard. There was no pedicle screw loosening, broken, non-fusion phenomenon. Al the lumbar interbody fusions were good. No one occurred secondary lumbar spinal stenosis. Experimental findings indicate that, lumbar pedicle screw fixation combined with interbody fusion cage for extremely lateral lumbar disc herniation, is characterized as fast symptom relief, strong fixation and good lumbar stability.
ABSTRACT
Objective: Many studies have focused on the association between the ABCB1 3435C>T polymorphism and colorectal cancer [CRC] risk. However, the results were conflicting. The aim of this meta-analysis is to evaluate the precise association between this polymorphism and CRC risk
Methods: We formally reviewed the literature at Pubmed, EMBASE and the Cochrane Library with the key words as follows: ABCB1/MDR1/P-glycoprotein, polymorphism, colorectal and cancer/neoplasm/tumor. This meta-analysis was assessed by Review manager 5.0. The fixed-effects model was used to pool the odds ratios [OR] with 95% confidence intervals [CI] for CRC risk
Results: There were 8 studies identified. The pooled OR with 95% CI of CC+CT versus TT genotype of the ABCB1 3435C>T polymorphism for CRC risk was 1.01 [0.90-1.13]. The sensitivity analysis further confirmed the result. Heterogeneity and publication bias were not observed in this meta-analysis
Conclusions: In summary, there was no significant association between the ABCB1 3435C>T polymorphism and CRC risk
ABSTRACT
<p><b>OBJECTIVE</b>To verify the clinical efficacy of shu-stream point acupuncture combined with fire needle therapy in the treatment of hand osteoarthritis.</p><p><b>METHODS</b>Eighty cases were randomized into an acupuncture group (shu-stream point acupuncture combined with fire needle therapy) and a medication group(votalin emulgel). For the 42 cases in the acupuncture group, acupuncture at shu-stream points on the three yang meridians of the hand including Sanjian (LI 3), Zhongzhu (TE 3), Houxi (SI 3) and fire needle at Ashi points were applied, the treatments were given once every other day, 15 times as a treatment course. For the 38 cases in the medication group, votalin emulgel was prescribed for local embrocation, twice a day, 30 days as a treatment course. The visual analogue scale (VAS) of arthralgia, joint function score and the duration of morning stiffness, joint tenderness, swelling were observed before and after treatment in both groups.</p><p><b>RESULTS</b>After two courses of clinical treatment, the VAS score of arthralgia, joint function score and the duration of morning stiffness, joint tenderness, swelling were statistically significant differences as compared with before treatment (all P < 0.01 ), the efficacy in the acupuncture group was superior to that in the medication group (all P < 0.01 ). The cured-markedly effective rate and total effective rate were 61.9% (26/42) and 95.2% (40/42) in the acupuncture group, and 36.8% (14/38) and 76.3% (29/38) in the medication group respectively, with statistically significant differences between the two groups (both P < 0.05).</p><p><b>CONCLUSION</b>Shu-stream point acupuncture combined with fire needle therapy achieves a significant efficacy in the treatment of hand osteoarthritis.</p>
