[Comprehensive therapy of traditional Chinese medicine for erectile dysfunction with damp-heat stasis: A clinical observation of 103 cases].

OBJECTIVE: To assess the clinical effect and safety of comprehensive therapy of traditional Chinese medicine (TCM) in the treatment of erectile dysfunction (ED) with damp-heat stasis. METHODS: We selected 108 cases of ED with damp-heat stasis meeting the inclusion criteria and treated with tadalafil (the control group, n = 54) or tadalafil + comprehensive TCM therapy (the trial group, n = 54) in the First Affiliated Hospital of Henan University of Chinese Medicine in the same period. After 8 weeks of treatment, we recorded the patients' scores on IIEF-5, TCM syndrome, erectile quality (EQS), 9-Item Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Scale 7 (GAD-7). At 16 weeks of our study, we collected the efficacy parameters, safety indicators and adverse reactions by telephone follow-up and compared the data obtained between the two groups of patients. RESULTS: Totally, 103 of the patients completed the study, 51 in the control and 52 in the trial group. Compared with the baseline, the IIEF-5 and EQS scores were both markedly increased after 8 weeks of treatment in the trial group (12.35±3.00 vs 18.36±2.82, P< 0.05; 39.5 ï¼»30.25－43ï¼½ vs 67.5 ï¼»54.5－76.75ï¼½, P< 0.05) and the control (11.96±2.79 vs 15.88±3.86, P< 0.05; 38.0 ï¼»29－42ï¼½ vs 56 ï¼»49－64ï¼½, P< 0.05), even more significantly in the former than in the latter (P< 0.05); the TCM syndrome and GAD-7 scores were remarkably decreased in the trial (9.5 ï¼»8－12ï¼½ vs 4.0 ï¼»2.25－5ï¼½, P< 0.05; 5 ï¼»2.25－6.75ï¼½ vs 2.5 ï¼»1－4.75ï¼½, P< 0.05) and the control group (10.0 ï¼»8－12ï¼½ vs 5.0 ï¼»3－6ï¼½, P< 0.05; 5.0 ï¼»3－6ï¼½ vs 4.0 ï¼»2－5ï¼½, P< 0.05), even more significantly in the former than in the latter (P< 0.05), so were the PHQ-9 scores (P< 0.05), but with no statistically significant difference between the two groups (P > 0.05). The IIEF-5 scores of the two groups remained significantly higher than the baseline during the follow-up (P< 0.05), even higher in the trial than in the control group (17.04±2.60 vs 14.16±3.34, P< 0.05). No obvious abnormal safety indicators or adverse events were observed during the study. CONCLUSION: Comprehensive TCM therapy combined with tadalafil is superior to tadalafil alone in the treatment of ED with damp-heat stasis, and has a better long-term efficacy and a higher safety.

[Effect of bird-induced anus-lifting surgery combined with oral Relinqing Granules on LUTS/CP with damp heat syndrome: Evaluation by infrared thermal imaging].

OBJECTIVE: To observe the clinical effect of bird-induced anus-lifting surgery (BIAL) combined with oral Relinqing Granules (RG) in the treatment of lower urinary tract symptoms / chronic prostatitis (LUTS/CP) with damp-heat syndrome using infrared thermal imaging (ITI). METHODS: This study included 165 cases of LUTS/CP with damp-heat syndrome treated in the Departments of Andrology and Urology of our hospital, which were divided into three groups of an equal number and treated by medication of oral tamsulosin hydrochloride at 0.2 mg, qd plus levofloxacin at 0.2 g bid (control), anus-lifting exercise (15 lifts once a day) combined with oral RG at 8 g tid (routine treatment) and BIAL (15 lifts once a day) combined with oral RG at 8 g tid (BIAL+RG), respectively, all for two weeks. We recorded the ITI indicators, NIH-CPSI and Self-Rating Anxiety Scale (SAS) scores of patients before and after treatment, observed adverse reactions during the treatment, and compared them among the three groups of patients. RESULTS: Compared with the baseline, NIH-CPSI and SAS scores were significantly reduced in all the three groups after treatment (P < 0.05), even more significantly in the BIAL+RG (10.49 ± 2.97 and 49.73 ± 2.79) than in the control (21.15 ± 3.56 and 52.62 ± 5.38) and routine treatment groups (15.55 ± 2.77 and 52.35 ± 3.87) (P < 0.05). The ITI temperature at the related parts of the body was remarkably decreased in the three groups after treatment (P < 0.05), even lower in the BIAL+RG group (30.47 ± 1.61, 32.14 ± 1.25, 31.16 ± 1.58, 31.97 ± 1.19) than in the control (33.39 ± 0.6, 33.64 ± 1.07, 32.78 ± 0.58, 33.18 ± 0.78) and routine treatment groups (31.93 ± 1.14, 33.06 ± 0.8, 33.08 ± 0.82, 33.17 ± 1.05) (P < 0.05), with statistically significant difference from the baseline in the BIAL+RG group after 12 hours and 24 hours of treatment (ï¼»34.26 ± 0.06ï¼½ vs ï¼»32.65 ± 0.05ï¼½ and ï¼»32.72 ± 0.09ï¼½, P < 0.05), but not between the two time points (P > 0.05). The incidence rate of adverse reactions was markedly lower in the BIAL+RG and routine treatment groups than in the control (P < 0.05) but not significantly different between the BIAL+RG and routine treatment groups (P > 0.05). CONCLUSION: Bird-induced anus-lifting surgery combined with oral Relinqing Granules can safely and significantly improve infrared thermal imaging indicators and NIH-CPSI scores in LUTS/CP patients with damp-heat syndrome.

One-step chromatographic procedure for purification of B-phycoerythrin from Porphyridium cruentum.

B-phycoerythrin (B-PE) was separated and purified from microalga Porphyridium cruentum using one-step chromatographic method. Phycobiliproteins in P. cruentum was extracted by osmotic shock and initially purified by ultrafiltration. Further purification was carried out with a SOURCE 15Q exchange column and analytical grade B-PE was obtained with a purity ratio (A545/A280) of 5.1 and a yield of 68.5%. It showed a double absorption peaks at 545 nm and 565 nm and a shoulder peak at 498 nm, and displayed a fluorescence emission maximum at 580 nm. The analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed a bulky band between 18 and 20 kDa which could be assigned to subunits α and ß and a low intensity band of 27 kDa assigned to γ subunit. Our protocol provides attractive alternative to consider for the purification procedure to obtain analytical grade B-PE at commercial level.

[Three-dimensional finite element analysis of lumbar disc herniation under different body positions].

OBJECTIVE: To campare biomechanical effects of different postural compression techniques on three-dimensional model of lumbar disc herniation (LDH) by finite element analysis. METHODS: Lumbar CT image of a 48-year-old female patient with LDH (heighted 163 cm, weighted 53 kg) was collected. Mimics 20.0, Geomagic Studio, Solidwords and other software were used to establish three-dimensional finite element model of LDH on L4,5 segments. Compression techniques under horizontal position, 30° forward bending and 10° backward extension were simulated respectively. After applying the pressure, the effects of compression techniques under different positions on stress, strain and displacement of various tissues of intervertebral disc and nerve root were observed. RESULTS: L4, 5 segment finite element model was successfully established, and the model was validated. When compression manipulation was performed on the horizontal position, 30° flexion and 10° extension, the annular stress were 0.732, 5.929, 1.286 MPa, the nucleus pulposus stress were 0.190, 1.527, 0.295 MPa, and the annular strain were 0.097, 0.922 and 0.424, the strain sizes of nucleus pulposus were 0.153, 1.222 and 0.282, respectively. The overall displacement distance of intervertebral disc on Y direction were -3.707, -18.990, -4.171 mm, and displacement distance of nerve root on Y direction were +7.836, +5.341, +3.859 mm, respectively. The relative displacement distances of nerve root and intervertebral disc on Y direction were 11.543, 24.331 and 8.030 mm, respectively. CONCLUSION: Compression manipulation could make herniated intervertebral disc produce contraction and retraction trend, by increasing the distance between herniated intervertebral disc and nerve root, to reduce symptoms of nerve compression, to achieve purpose of treatment for patients with LDH, in which the compression manipulation is more effective when the forward flexion is 30°.

Attitudes and influencing factors associated with smoking cessation: An online cross-sectional survey in China.

INTRODUCTION: Quitting smoking, the critical path to reach the global targets of reducing tobacco use, can bring major and immediate health benefits to smokers. Exploring factors that help individuals to quit smoking is of great importance. The present study explored influencing factors on smoking cessation, in order to provide comprehensive reference for tobacco control policies. METHODS: Ex-smokers and current smokers were recruited online in this cross-sectional survey, from 1 October to 31 November 2022, in China. The observational data were collected using a questionnaire to collect information with respect to sociodemographic characteristics of smokers, attitudes towards smoking cessation, details of smoking cessation, and different potential factors related to smoking cessation through open-ended questions. RESULTS: A total of 638 smokers from 30 provinces were recruited as eligible respondents, with a mean age of 37.3 ± 11.7 years and a mean smoking history of 15.9 ± 13.7 years. The percentage of males was 92.3%. Of the 638 respondents, only 3.9% had no intention to stop smoking. Among 155 subjects who had quitted smoking successfully, willpower (55.5%) was considered as the most important contributing factor. Among 365 subjects who tried to quit but failed, lack of willpower (28.2%), tobacco dependence (16.2%), influence of surrounding smokers or smoking environments (15.9%), bad moods (9.9%), stress from work or life (7.9%), habits (7.1%), socialization (4.1%), and easy availability of tobacco (2.7%) were considered as the adverse factors leading to failure in quitting smoking. CONCLUSIONS: Willpower and support from family members were the vital factors that lead to successful smoking cessation. Future tobacco control policies should also focus on addressing withdrawal symptoms and creating smoke-free environments as well as other factors.

Bradyrhizobium aeschynomenes sp. nov., a root and stem nodule microsymbiont of Aeschynomene indica.

Aeschynomene indica has a distinctive symbiosis with Bradyrhizobium in which nodulation is Nod factor-independent. In this study, we characterised three Gram-negative and rod-shaped strains (83002T, 81013 and 83012) isolated from root nodules of Aeschynomene indica in Shandong Peninsula. The major cellular fatty acids of isolates were C16:0, C18:0, C18:1 ω7c 11-methyl, summed feature 3 and summed feature 8. The major polar lipids were phosphatidylethanolamine (PE), aminolipids (AL) and phosphatidylcholine (PC). Phylogenetic analysis based on the 16S rRNA locus showed that they belonged to the Bradyrhizobium genus, and shared the highest similarity to the type strains Bradyrhizobium oligotrophicum S58T and Bradyrhizobium denitrificans LMG 8443T. As expected, analysis of concatenated sequences of six housekeeping genes (atpD, recA, glnII, dnaK, gyrB, and rpoB) and nifH gene proposed that these three strains formed a distinct clade within the genus Bradyrhizobium. The highest average nucleotide identity and DNA-DNA hybridization values of the three strains in comparison to the closest Bradyrhizobium species were 87.5% and 65.3%, respectively, which are far below the threshold of species delineation, and thus confirmed the three strains as a new species. The genome size of strain 83002T is 7.52 Mbp, and the DNA G+C content is 65.42 mol%. Strain 83002T (=KCTC 82266T=MCCC 1K04775T) was chosen as the type strain of the new species, for which the name Bradyrhizobium aeschynomenes sp. nov. was proposed.

Chemical constituents from the bulbs of Lilium davidii var. unicolor and anti-insomnia effect.

In this work, twenty-five water-soluble constituents were isolated from the bulbs of Lilium davidii var. unicolor, including two new compounds termed liliumtides A and B (1-2), and seventeen known compounds (3-4, 6-13, 15, 17, 21-25) isolated from the genus of Lilium for the first time. Their structures were established using high-resolution electrospray ionization mass spectroscopy and 1D and 2D nuclear magnetic resonance data. To confirm furtherly the absolute configuration of liliumtide A, and to accumulate enough sample to study the anti-insomnia effect, a total synthesis for liliumtide A was achieved by four steps. The pentobarbital-induced sleeping time test showed that compared with the blank control group, the liliumtide A decreased sleep latency and significantly increased the sleep time. These results suggested that liliumtide A could be investigated as a natural anti-insomnia lead compound in the pharmaceutical and food industries.

Cervical spondylotic myelopathy with syringomyelia presenting as hip Charcot neuroarthropathy: A case report and review of literature.

BACKGROUND: Charcot neuroarthropathy (CN) is a systemic disease characterized by progressive bone loss and destruction, which is usually closely related to diabetes, HIV, etc. However, CN caused by syringomyelia accounts for only 5% of CN cases; the shoulder and elbow are most often involved, and the hip joint is rarely affected. As a rare factor, cervical spondylotic myelopathy (CSM) can be associated with syringomyelia, which is scarcely reported in the literature. Here, we present the first case report to date of CN of the hip caused by syringomyelia secondary to CSM. CASE SUMMARY: We describe a 76-year-old male patient who was diagnosed with CSM due to neck pain and weakness of limbs 16 years ago. Four years ago, he noticed recurrent swelling of the right hip with pain and was diagnosed with degenerative arthritis. Recently, however, his symptoms gradually worsened, and because of progressive pain, destabilization and weakness of the right hip, he was admitted to our hospital. Through systematic physical, radiographic and laboratory examinations, we finally reached a diagnosis: CN of the right hip associated with syringomyelia secondary to CSM. After comprehensive evaluation of the patient's condition, we performed right total hip arthroplasty. During the follow-up, the patient felt well clinically and could walk independently with a knee brace. CONCLUSION: We suggest a possible etiological association between CSM and syringomyelia, which may reflect a potential pathogenesis of CN. We encourage clinicians to actively carry out a detailed medical history and comprehensive physical and imaging examinations in patients with joint lesions, especially chronic shoulder neck pain, to rule out the possibility of this association, which plays a crucial role in the early diagnosis of CN. Arthroplasty may no longer be an absolute contraindication to surgical treatment of CN. Reasonable selection of the surgical strategy can markedly improve the clinical symptoms and quality of life of patients.

[Effects of Chinese herbal medicine Yiqi Huayu Bushen Recipe on expressions of aggrecan and type X collagen mRNAs in cells from degenerated human intervertebral discs].

OBJECTIVE: To investigate the effects of serum containing Yiqi Huayu Bushen Recipe, a compound Chinese herbal medicine, on expressions of aggrecan and type X collagen mRNAs of the degenerated intervertebral disc cells in patients with cervical spondylotic myelopathy. METHODS: Six inpatients diagnosed as cervical spondylotic myelopathy and undergoing cervical decompression and fusion surgery to remove the degenerated disc tissue were enrolled in this study. Primary intervertebral disc cells were isolated using small tissue mass method. Serum containing Yiqi Huayu Bushen recipe were obtained after SD rats were fed with Yiqi Huayu Bushen recipe for 3 days. MTT method was used to detect proliferation of the first-passage cells isolated from degenerated intervertebral discs and growth curve was drawn. In the following tests, the first-passage cells were cultured with the sera containing drugs and sodium chloride (NaCl), respectively. Proliferation of intervertebral disc cells was detected by MTT method and expressions of aggrecan and type X collagen mRNAs were detected by real-time polymerase chain reaction. RESULTS: The growth curve of the first-passage cells of the degenerated intervertebral discs showed that the time of cell proliferation peak was the sixth day. Compared with the same concentrations of NaCl solution, serum containing Yiqi Huayu Bushen Recipe at 5%, 10% and 20% promoted cell proliferation and expression of aggrecan mRNA and decreased expression of type X collagen mRNA (P<0.01). 10% serum containing Yiqi Huayu Bushen recipe was more effective than 5% and 20%. CONCLUSION: Yiqi Huayu Bushen Recipe inhibits degeneration of the intervertebral disc cells by regulating collagen and proteoglycan expressions.

Recovery from prolonged disorders of consciousness: A dual-center prospective cohort study in China.

BACKGROUND: Recent innovations in intensive care have improved the prognosis of patients with severe brain injuries and brought more patients with disorders of consciousness (DoC). Data are lacking regarding the long-term outcomes of those patients in China. It is necessary to study the long-term outcomes of patients with prolonged DoC in light of many factors likely to influence crucial decisions about their care and their life. AIM: To present the preliminary results of a DoC cohort. METHODS: This was a two-center prospective cohort study of inpatients with vegetative state (VS)/unresponsive wakefulness syndrome (UWS). The study outcomes were the recovery from VS/UWS to minimally conscious state (MCS) and the long-term status of patients with prolonged DoC considered in VS/UWS or MCS for up to 6 years. The patients were evaluated using the Glasgow coma scale, coma recovery scale-revised, and Glasgow outcome scale. The endpoint of follow-up was recovery of full consciousness or death. The changes in the primary clinical outcome improvement in clinical diagnosis were evaluated at 12 mo compared with baseline. RESULTS: The study population included 93 patients (62 VS/UWS and 31 MCS). The post-injury interval range was 28-634 d. Median follow-up was 20 mo (interquartile range, 12-37 mo). At the endpoint, 33 transitioned to an emergence from MCS or full consciousness, eight had a locked-in syndrome, and there were 35 patients remaining in a VS/UWS and 11 in an MCS. Seven (including one locked-in syndrome) patients (7.5%) died within 12 mo of injury. Compared with the unresponsive group (n = 52) at 12 mo, the responsive group (n = 41) had a higher proportion of males (87.8% vs 63.5%, P = 0.008), shorter time from injury (median, 40.0 d vs 65.5 d, P = 0.006), higher frequency of vascular etiology (68.3% vs 38.5%, P = 0.007), higher Glasgow coma scale score at admission (median, 9 vs 6, P < 0.001), higher coma recovery scale-revised score at admission (median, 9 vs 2.5, P < 0.001), at 1 mo (median, 14 vs 5, P < 0.001), and at 3 mo (median, 20 vs 6, P < 0.001), lower frequency of VS/UWS (36.6% vs 90.0%, P < 0.001), and more favorable Glasgow outcome scale outcome (P < 0.001). CONCLUSION: Patients with severe DoC, despite having strong predictors of poor prognosis, might recover consciousness after a prolonged time of rehabilitation. An accurate initial diagnosis of patients with DoC is critical for predicting outcome and a long-term regular follow-up is also important.

Evolutionary transition between invertebrates and vertebrates via methylation reprogramming in embryogenesis.

Major evolutionary transitions are enigmas, and the most notable enigma is between invertebrates and vertebrates, with numerous spectacular innovations. To search for the molecular connections involved, we asked whether global epigenetic changes may offer a clue by surveying the inheritance and reprogramming of parental DNA methylation across metazoans. We focused on gametes and early embryos, where the methylomes are known to evolve divergently between fish and mammals. Here, we find that methylome reprogramming during embryogenesis occurs neither in pre-bilaterians such as cnidarians nor in protostomes such as insects, but clearly presents in deuterostomes such as echinoderms and invertebrate chordates, and then becomes more evident in vertebrates. Functional association analysis suggests that DNA methylation reprogramming is associated with development, reproduction and adaptive immunity for vertebrates, but not for invertebrates. Interestingly, the single HOX cluster of invertebrates maintains unmethylated status in all stages examined. In contrast, the multiple HOX clusters show dramatic dynamics of DNA methylation during vertebrate embryogenesis. Notably, the methylation dynamics of HOX clusters are associated with their spatiotemporal expression in mammals. Our study reveals that DNA methylation reprogramming has evolved dramatically during animal evolution, especially after the evolutionary transitions from invertebrates to vertebrates, and then to mammals.

Apoptotic effect of organophosphorus insecticide chlorpyrifos on mouse retina in vivo via oxidative stress and protection of combination of vitamins C and E.

Organophosphorus insecticide poisoning is widely investigated, and a growing number of evidence indicates its effects to cause ocular lesions, but the mechanisms of its ocular effects are not well elucidated. Here, effects of organophosphorus insecticide chlorpyrifos on mouse retina in vivo and protection of combination of vitamins C and E were reported. Cell apoptosis, lipid peroxidation and DNA damage were increased, and activities of antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase were decreased in retina of chlorpyrifos-administrated mice (63mg/kg, single treatment, via oral gavage). Pretreatment of combination of antioxidants vitamin C (250mg/kg) and vitamin E (150mg/kg) (once daily for 6 days, hypodermic injecting) significantly attenuated these effects of chlorpyrifos, demonstrating oxidative stress was involved in chlorpyrifos-induced cell apoptosis in mouse retina. Moreover, chlorpyrifos treatment inhibited acetylcholinesterase activity and promoted [Ca(2+)](i) level in mouse retinal cells, which were also attenuated by combination of vitamins C and E. These results may have implications for treatment of organophosphorus insecticide poisoning in retina with combination of vitamins C and E.

MiR-214 inhibits cell migration, invasion and promotes the drug sensitivity in human cervical cancer by targeting FOXM1.

OBJECT: MicroRNAs (miRNAs) play key roles in progression of cervical cancer. In the present study, we investigated the role of miR-214 in the process of migration, invasion and drug sensitivity to cisplatin in cervical cancer. METHODS: We detected the differential expression of miR-214 in 19 cases cervical cancer tissues and normal tissues as well as 4 cervical cancer cells and one normal cervical cells by Real-time PCR. Then, wound healing assay, transwell invasion assay and MTT were used to detect the effects of migration, invasion and sensitivity to cisplatin of cervical cancer when miR-214 was overexpressed. Western blot, immunofluorescence and Flow Cytometry were used to detect the mechanism of migration, invasion and sensitivity to cisplatin. Next, bioinformatics analysis was used to find the target of miR-214. Through the luciferase reporter assay, Real-time PCR and western blot, we confirmed the binding relationship of miR-214 and FOXM1. In cervical cancer tissues, the expression of FOXM1 was detected by western blot and Immunohistochemistry. We also knocked down FOXM1 in cervical cancer cells, wound healing assay, transwell invasion assay and MTT were performed to detect the migration, invasion and sensitivity to cisplatin abilities of FOXM1. Western blot and Flow Cytometry were used to detect the mechanism of migration, invasion and sensitivity to cisplatin by FOXM1. Finally, we performed rescue expriments to confirm the function relationship between miR-214 and FOXM1. RESULTS: 1. Our results showed that miR-214 was frequently downregulated in tumor tissues and cancer cells especially in CIN III and cervical cancer stages. 2. Overexpression of miR-214 significantly inhibited migration and invasion of cervical cancer cells and prompted the sensitivity to cisplatin. 3. FOXM1 was identified as a target of miR-214 and down-regulated by miR-214. 4. Knocking down FOXM1 could inhibited migration and invasion of cervical cancer cells and prompted the sensitivity to cisplatin. 5. FOXM1 was upregulated in tumor tissues. 6. The mechanism of migration, invasion and sensitivity to cisplatin were the resluts of changes of EMT and apoptosis. 7. The restoration of FOXM1 expression can counteract the effect of miR-214 on cell migration, invasion and sensitivity to cisplatin of cervical cancer cells. CONCLUSIONS: These findings indicate that miR-214 acts as a tumor suppressor during the process of migration, invasion and drug sensitivity through targeting FOXM1, suggesting miR-214 as a potential new diagnostic and therapeutic target for the treatment of cervical cancer.

Connecting the P300 to the diagnosis and prognosis of unconscious patients.

The residual consciousness of unconscious patients can be detected by studying the P300, a wave among event-related potentials. Previous studies have applied tones, the subject's name and other names as stimuli. However, the results were not satisfactory. In this study, we changed the constituent order of subjects' two-character names to create derived names. The subject's derived names, together with tones and their own names, were used as auditory stimuli in event-related potential experiments. Healthy controls and unconscious patients were included in this study and made to listen to these auditory stimuli. In the two paradigms, a sine tone followed by the subject's own name and the subject's derived name followed by the subject's own name were used as standard and deviant stimuli, respectively. The results showed that all healthy controls had the P300 using both paradigms, and that the P300 in the second paradigm had a longer latency and two peaks. All minimally conscious state patients had the P300 in the first paradigm and the majority of them had the P300 in the second paradigm. Most vegetative state patients had no P300. Patients who showed the P300 in the two paradigms had more residual consciousness, and patients with the two-peak P300 had a higher probability of awakening within a short time. Our experimental findings suggest that the P300 event-related potential could reflect the conscious state of unconscious patients.

[Discussion on the regular of acupoint selection of acupuncture and moxibustion for lumbar disc herniation during recent 10 years].

By taking "lumbar disc herniation", Chinese medicine", "acupuncture and moxibustion" as key words Chinese articles about acupuncture for lumbar disc herniation in recent 10 years were searched in three major Chinese databases of Wan fang database, VIP database and CNKI. Totally 546 relative articles were retrieved. After the elimination of invalid articles, 173 were included as valid articles with 49 main acupoints. The hierarchical clustering statistical method was used to analyze the possible rules among the former 20 acupoints. It turned out that there were 10 most common used acupoints on Bladder Meridian [Geshu (BL 17), Xiaochangshu (BL 27), Shenshu (BL 23), Dachangshu (BL 25), Pangguangshu (BL 28), Guanyuanshu (BL 26), Weizbong (BL 40), Zhibian (BL 54), Chengshan (BL 57), Kunlun (BL 60)], 2 on Gallbladder Meridian [Huantiao (GB 30), Yanglingquan (GB 34)], 2 on Governor Vessel [Yaoyangguan (GV 3), Shuigou (GV 26)], 2 on Stomach Meridian [Zusanli (ST 36), Juliao (ST 3)], 2 on Spleen Meridian [Sanyinjiao (SP 6), Xuehai (SP 10)], and the rest were extra points (Huatuo Jiaji) and Ashi points, so a conclusion could be drawn that the most common used acupoints were Bladder Meridian acupoints and supplemented by Gallbladder Meridian, Governor Vessel, Stomach Meridian, Spleen Meridian, extra points and Ashi points. The selected acupoints were most located on the lumbosacral region, leg and fewer located on the face, back and local part.

[Analysis of therapeutic effect of acupuncture at neiguan (PC 6) and zusanli (ST 36) on acute renal colic].

OBJECTIVE: To observe the efficacy differences among acupuncture at Neiguan (PC 6) and Zusanli (ST 36), dolantin and scopolamine in treatment of acute renal colic, and to verify the clinical effect of acupuncture at Neiguan (PC 6) and Zusanli (ST 36). METHODS: Two hundred and forty patients were randomly divided into an acupuncture group, a scopolamine group and a dolantin group, 80 cases in each group. The acupuncture group was treated by acupuncture at unilateral or bilateral Neiguan (PC 6) and Zusanli (ST 36). The scopolamine group was treated by intramuscular injection of scopolamine combined with intravenous drip of scopolamine, and the dolantin group was treated by intramuscular injection of dolantin. The clinical therapeutic effects were observed 30 min after drug administration or acupuncture, and the onset time of effect and adverse reactions were compared among the groups. RESULTS: The total effective rate of 95.0% (76/80) in the acupuncture group had a similar therapeutic effect to 92.5% (74/80) in dolantin group (P>0.05), which were both superior to 76.3% (61/80) in scopolamine group (both P<0.05). The onset time of (13.24 +/- 2.12) min in the acupuncture group was significant earlier than (23.11 +/- 6.22) min in scopolamine group and (22.17 +/- 3.15) min in dolantin group (both P<0.05), and compared with the other two groups, the adverse reactions in the acupuncture group were significant decreased (both P<0.05). CONCLUSION: Acupuncture at Neiguan (PC 6) and Zusanli (ST 36) has a good analgesic effect with a low incidence of adverse reactions, which is superior to that of dolantin and scopolamine.

[Effect of yupingfengsan on the growth of tumor and immunological function in tumor-bearing mice].

AIM: To explore the effect of yupingfengsan on the growth of tumor and immunological function in tumor-bearing mice. METHODS: The models of tumor-bearing mice were established by inoculating the healthy mice with S180 tumor carneus cells cultured in vitro. Then the ratio of tumor restriction was calculated. The phagocytosis activity of phagocytes, the level of NO secreted by phagocytes, the proliferating activity of T lymphocytes and the level of IL-2 were detected in the mice after being treated with yupingfengsan 12 days. RESULTS: yupingfengsan elevated the phagocytosis of phagocytes and the level of NO secreted by phagocytes. It promoted T lymphocytes to transform, and increased the level of IL-2 and the activity of NK cells. CONCLUSION: yupingfengsan can increase the immunological function of tumor-bearing mice and suppress the development of tumor in mice.
