A novel surgical technique for spontaneous intracerebral hematoma evacuation.

Stereotactic removal of intracerebral hematoma is a routine procedure for treating hypertensive intracerebral hemorrhage, but the complex sequence of operations limits its adoption. We explored the application of a novel surgical technique for the removal of spontaneous intracerebral hematomas. The surgical technique based on computed tomography (CT) images was used in hematoma projection and surgical planning. Markers placed on the scalp based on an Android smartphone app allowed the installation of a stereotactic head frame to facilitate the selection of the best trajectory to the hematoma center for removing the hematoma. Forty-two patients with spontaneous intracerebral hemorrhage were included in the study, including 33 cases of supratentorial hemorrhage, 5 cases of cerebellum hemorrhage, and 4 cases of brain stem hemorrhage. The surgical technique combined with the stereotactic head frame helped the tip of the drainage tube achieve the desired position. The median surgical time was 45 (range 25-75) min. The actual head frame operating time was 10 (range 5-15) min. Target alignment performed by the surgical technique was accurate to ≤ 10.0 mm in all 42 cases. No patient experienced postoperative rebleeding. In 33 cases of supratentorial intracerebral hemorrhage, an average evacuation rate of 77.5% was achieved at postoperative 3.1 ± 1.4 days, and 29 (87.9%) cases had a residual hematoma of < 15 ml. The novel surgical technique helped to quickly and effortlessly localize hematomas and achieve satisfactory hematoma removal. Clinical application of the stereotactic head frame was feasible for intracerebral hemorrhage in various locations.

Multivariate weighted recurrence network analysis of EEG signals from ERP-based smart home system.

Smart home has been widely used to improve the living quality of people. Recently, the brain-computer interface (BCI) contributes greatly to the smart home system. We design a BCI-based smart home system, in which the event-related potentials (ERP) are induced by the image interface based on the oddball paradigm. Then, we investigate the influence of mental fatigue on the ERP classification by the Fisher linear discriminant analysis. The results indicate that the classification accuracy of ERP decreases as the brain evolves from the normal stage to the mental fatigue stage. In order to probe into the difference of the brain, cognitive process between mental fatigue and normal states, we construct multivariate weighted recurrence networks and analyze the variation of the weighted clustering coefficient and weighted global efficiency corresponding to these two brain states. The findings suggest that these two network metrics allow distinguishing normal and mental fatigue states and yield novel insights into the brain fatigue behavior resulting from a long use of the ERP-based smart home system. These properties render the multivariate recurrence network, particularly useful for analyzing electroencephalographic recordings from the ERP-based smart home system.

[Application of Tri-Jiao Theory in the treatment of male immune infertility].

Male immune infertility is a common disease with an incidence rate of about 10%. This article aimed to find some breakthrough clues to the etiology and pathogenesis of male immune infertility from years of relevant studies in traditional Chinese medicine (TCM). Some consensuses on the diagnosis, etiology and pathogenesis of the disease are based on limited and isolated understandings. With the Tri-Jiao Theory as the breakthrough point, we analyzed the three studies by the Xu Fu-song Group and discussed the causes, development and outcome of male immune infertility from the aspects of its positioning, transmission and syndrome differentiation. The Tri-Jiao Theory reflects the holistic thought of TCM and offers a comprehensive insight into the dynamic changes of the disease. As the basis for TCM understanding of male immune infertility, studies on the mucosal immune system have provided some new ideas for applying the Tri-Jiao Theory to TCM researches into the disease.

Each prescription was made up of 14 traditional Chinese drugs on average. The cure rate was 32% , and the effective rate was 85%. Professor Xu Fu-song advanced and proved some new theories and therapeutic methods. CONCLUSION: Professor Xu Fu-song's TCM protocols can be applied to a wide range of male diseases, mostly complicated, and are characterized by accurate differentiation of symptoms and signs, high drug compliance, and excellent therapeutic efficacy.

Acupuncture for aqueous deficiency dry eye: a randomized controlled trial. / é’ˆåˆºæ²»ç–—æ°´æ¶²ç¼ºä¹åž‹å¹²çœ¼ï¼šéšæœºå¯¹ç §è¯•éªŒ.

OBJECTIVES: To compare the clinical efficacy and safety of acupuncture and sodium hyaluronate eye drop in the treatment of aqueous deficiency dry eye. METHODS: A total of 60 patients (120 eyes) with aqueous deficiency dry eye were randomly divided into an observation group (30 cases, 1 case dropped out) and a control group (30 cases, 1 case dropped out). In the control group, sodium hyaluronate eye drop were used, one drop at a time, 4 times a day, for 14 consecutive days. In the observation group, acupuncture was applied at bilateral Shangjingming (Extra), Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5), and Tongziliao (GB 1) , once a day, treatment for 6 days with the interval of 1 day was required, for 14 consecutive days. The tear meniscus height (TMH), Schirmer Ⅰ test (SⅠT), ocular surface disease index (OSDI) score, non-invasive tear break-up time (NIBUT), and corneal fluorescein sodium staining (FLS) score were compared between the two groups before and after treatment, and the safety of the treatment of the two groups was observed. RESULTS: Compared with those before treatment, after treatment, TMH, SⅠT and NIBUT were increased (P<0.01, P<0.05), and FLS scores were decreased (P<0.01) in the two groups; the score of OSDI was reduced (P<0.01) in the observation group. After treatment, in the observation group, TMH and SⅠT were higher than those in the control group (P<0.01), and the score of OSDI was lower than that in the control group (P<0.01). No adverse reactions and adverse events were observed in the two groups. CONCLUSIONS: Acupuncture and sodium hyaluronate eye drop can both effectively treat aqueous deficiency dry eye, acupuncture has obvious advantages in improving TMH and basic tear secretion, and reducing the subjective symptoms of patients. Acupuncture for dry eye is safe.

Acupuncture promotes tear secretion by up-regulating VIP/cAMP/PKA/AQP5 signaling in guinea pigs with aqueous tear deficiency dry eye. / 基于VIP/cAMP/PKA/AQP5信号通路探讨针刺治疗水液缺乏型干眼的作用机制.

OBJECTIVES: To observe the effect of acupuncture on the ocular surface symptoms and the protein expression of vasoactive intestinal peptide (VIP) / cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) / aquaporin 5(AQP5) signaling pathway in lacrimal gland tissue of aqueous tear deficiency (ATD) type dry eye model, so as to investigate its mechanism underlying improvement of ATD. METHODS: British shorthair guinea pigs were randomly divided into blank control, model, acupuncture, sham-acupuncture and medication group, with 8 guinea pigs in each group. The ATD model was established by subcutaneous injection of scopolamine hydrobromide (0.6 mg/dose, 4 times/d for 10 days). For guinea pigs of the acupuncture group, filiform needles were inserted into bilateral "Jingming"(BL1), "Cuanzhu"(BL2), "Sizhukong"(TE23), "Taiyang"(EX-HN5), and "Tongziliao"(GB1) for 15 min. For guinea pigs of the sham-acupuncture group, a blunt filiform needle was used to repeatedly prick (not pierce) the skin of the same acupoints mentioned above. The treatment in the above two groups was conducted once daily for 14 days. The guinea pigs in the medication group received administration of sodium hyaluronate eye drops in both eyes, three times a day for 14 days. The objective tests of tear film break-up time (BUT), corneal fluorescein staining score (FLS) and phenol red thread (PRT) test were conducted before and after modeling and after the intervention. After the intervention, the lacrimal index (weight of lacrimal gland/body weight) was calculated. Histopathological changes of the lacrimal gland were observed after H.E. staining. The expression of AQP5 in the lacrimal gland were detected by immunofluorescence, and the contents of VIP and AQP5 in the lacrimal gland were measured by ELISA, the protein expression levels of VIP, cAMP, PKA, p-PKA and AQP5 in the lacrimal gland were detected by Western blot. RESULTS: In comparison with the blank control group, the PRT, BUT, lacrimal index, AQP5 immunoactivity, contents of VIP and AQP5, and protein expression levels of VIP, cAMP, PKA, p-PKA and AQP5 were significantly decreased(P<0.01, P<0.05), and FLS was obviously increased (P<0.01) in the model group . Compared to the model group, the PRT, BUT, lacrimal index, AQP5 immunoactivity, contents of VIP and AQP5, and expression levels of VIP and AQP5 in both acupuncture and medication groups, and the expression levels of cAMP, PKA, p-PKA in the acupuncture group were considerably increased (P<0.01, P<0.05), while the FLS was markedly decreased in both acupuncture and medication groups (P<0.01, P<0.05). Compared with the medication group, the acupuncture group had increased PRT (P<0.05). CONCLUSIONS: Acupuncture intervention is effective in reducing ocular surface damage and promoting tear secretion in guinea pigs with ATD, which may be related to its function in activating VIP/cAMP/PKA signaling, and promoting the expression of AQP5 in the lacrimal gland.

[Acupuncture mitigates ocular surface inflammatory response via α7nAChR/NF-κB p65 signaling in dry eye guinea pigs].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the ocular surface inflammation and α7 nicotinic acetylcholine receptor (α7nAChR) / nuclear factor kappa-B (NF-κB) p65 signal pathway in guinea pigs with dry eye, so as to explore its underlying mechanism. METHODS: A total of 32 male British tricolor short haired guinea pigs were randomized into blank control, model, EA and sham acupuncture groups, with 8 guinea pigs in each group. The dry eye model was established by subcutaneous injection of scopolamine hydrobromide solution (0.6 mg/0.2 mL each time, 4 times a day for 10 days). Guinea pigs of the EA group was treated with EA at bilateral "Cuanzhu" (BL2) and "Taiyang" (HN5), and manual acupuncture at bilateral "Jingming" (BL1), "Sizhukong" (SJ23), "Tongziliao" (GB1) for 15 min, once daily for 14 days. For animals of the sham acupuncture group, a blunt needle was used to prick the skin surface of the acupoints, the acupoint selection and stimulation time were the same as those in the EA group. Before and after modeling and after the intervention, the breakup time (BUT) of lacrimal film, sodium fluorescein coloring (Fl) state of corneal epithelium and phenol red thread (PRT) moist length were recorded for assessing the severity of dry eye. The density of activated immune cells around the corneal epithelial stromal cells was determined by corneal confocal microscopy. The contents of interleukin-4 (IL-4), IL-6, IL-10, tumor necrosis factor α (TNF-α) in the cornea and lacri-mal gland tissues were determined by ELISA, and the expression levels of α7nAChR and NF-κB p65 in the cornea and lacrimal gland were detected by immunohistochemistry and Western blot, separately. RESULTS: Compared with the blank control group, the corneal Fl, density of activated immune cells of corneal epithelium, contents of IL-6, IL-10 and TNF-α in both corneal and lacrimal gland tissues, NF-κB p65 cell positive rate and protein expression of lacrimal gland and corneal tissues were significantly increased (P<0.01, P<0.05), while the BUT, PRT and lacrimal gland α7nAChR cell positive rate considerably decreased (P<0.01) in the model group. In comparison with the model group, the level of corneal Fl, density of the activated immune cells of corneal epithelium, contents of corneal and lacrimal IL-6 and TNF-α, and corneal and lacrimal NF-κB p65 cell positive rates and protein expressions were remarkably down-regulated in the EA group (P<0.01, P<0.05), rather than in the sham acupuncture group (P>0.05) except content of corneal IL-10, lacrimal NF-κB p65 cell positive rate and lacrimal α7nAChR protein expression, whereas the levels of BUT, PRT, corneal and lacrimal IL-10 and corneal and lacrimal α7nAChR cell positive rates and protein expressions significantly up-regulated in the EA group (P<0.01, P<0.05), rather than in the sham acupuncture group (P>0.05) except corneal TNF-α and corneal NF-κB p65 protein expression. CONCLUSION: EA can improve corneal and lacrimal function in dry eye guinea pigs, which may be associated with its actions in increasing the expression of α7nAChR, inhibiting the nuclear translocation of NF-κB, and reducing the activated immune cells and inflammatory reaction.

Acupuncture combined with traditional Chinese medicine e-aid cognitive behavioral therapy for insomnia (TCM-eCBT-I) for chronic insomnia: study protocol for a randomized controlled trial.

INTRODUCTION: The incidence of insomnia is getting higher and higher. Long-term insomnia seriously affects people's health. Drug use is usually accompanied with adverse events. Both acupuncture and cognitive behavioral therapy for insomnia (CBT-I) have been proven to be safe and effective non-pharmacological treatments for insomnia. As the insomniacs' bad sleep behavior and wrong cognition have not been effectively corrected, acupuncture has a quick effect, high patient compliance but unstable long-term efficacy, while CBT-I is complex, time-consuming, and expensive; additionally, patient compliance is low, and the number of trained therapists is limited, making it difficult to carry out. Therefore, this study aims to use the insomnia TCM system to construct a convenient and feasible traditional Chinese medicine e-aid cognitive behavioral therapy for insomnia (TCM-eCBT-I) for Chinese people, and combine the advantages of acupuncture and TCM-eCBT-I for maintaining long-term efficacy, and three treatments will be evaluated to provide clinicians with a more effective clinical protocol METHODS AND ANALYSIS: This study is a single-center, open-label, randomized controlled trial. Ninety subjects will be recruited and randomly assigned to three groups: the acupuncture group, the TCM-eCBT-I group, and the acupuncture combined with TCM-eCBT-I group, in a ratio of 1:1:1. We will evaluate the Pittsburgh Sleep Quality Index (PSQI) and Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS), Insomnia Severity Index (ISI), sleep diary, Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and Fatigue Scale-14 Scale (FS-14) scales. All adverse reactions will be assessed through the ADVERSE event table. All outcomes will be evaluated online at 0 weeks, 4 weeks, 8 weeks, 16 weeks, and 28weeks. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of the Affiliated Hospital of Nanjing University of Chinese Medicine (2020 NL-018-02). Informed consent will be obtained from all the subjects. The results will be shared with sleep researchers, public, and relevant academic institutions through high-impact peer-reviewed publications. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2000032960. Registered on 17 May 2020.

[Clinical therapeutic effect on bronchial asthma by the observation of skin reaction after acupoint application based on chronic disease management platform of asthma].

OBJECTIVE: To compare the therapeutic effect on bronchial asthma between presence of skin reaction and the absence of skin reaction after acupoint application. METHODS: Sixty-one patients with bronchial asthma were treated with acupoint application during the hottest periods of summer ("dog days"). The acupoints included Dingchuan (EX-B 1), Feishu (BL 13), Xinshu (BL 15), Pishu (BL 20) and Shenshu (BL 23). The treatment was given once every 7 days, with the herbal plaster remained for 6 h each time, and 4 treatments were required totally. According to the local skin reaction after acupoint application, a skin reaction group (30 cases, 2 cases dropped off) and a non-skin reaction group (31 cases) were divided. Separately, before treatment and 1 year after treatment, using chronic disease management platform of asthma, the number of asthma attacks, the score of asthma control test (ACT) and the score of asthma quality of life questionnaire (AQLQ) were recorded online. Besides, the therapeutic effect was observed in the two groups 1 year after treatment. RESULTS: One year after treatment, the number of asthma attacks was reduced as compared with that before treatment in the patients of either group (P<0.001), the score of ACT and each domain in AQLQ, i.e. activity limitation, asthma symptoms, psychological state, reactions to stimuli and self-health care as well as the total scores of AQLQ were all increased as compared with those before treatment (P<0.001). The number of asthma attacks in the skin reaction group was less than the non-skin reaction group (P<0.05), the score of ACT and each domain of AQLQ and the total scores of AQLQ were all higher than the non-skin reaction group successively (P<0.05, P<0.01). The total effective rate was 82.1% (23/28) in the skin reaction group, better than 67.7% (21/31) in the non-skin reaction group (P<0.05). CONCLUSION: In treatment of acupoint application for bronchial asthma, the clinical therapeutic effect is better in the patients with local skin reaction after acupoint application. The chronic disease management platform of asthma is convenient for online evaluation.

Effect of Acupuncture on Cognitive Function of Insomnia Patients Compared with Drugs: A Protocol for Meta-analysis and Systematic Review.

Insomnia, one of the most common sleep disorders, is thought to have an adverse effect on cognitive function. At the same time, people with cognitive dysfunction are more prone to insomnia. At present, pharmacotherapy is the main treatment for insomnia, but there are some shortcomings such as poor long-term efficacy and potential dependence. There is some evidence that acupuncture has some advantages in alleviating insomnia and improving cognitive function. This study is aimed at investigating the effects of acupuncture and drugs on cognitive function in patients with insomnia and evaluating the efficacy and safety of these two interventions, providing strong evidence for clinical decision-making. The study will retrieve eight major databases: China National Knowledge Infrastructure, Wanfang Database, VIP Database for Chinese Technical Periodicals, SinoMed, PubMed, Web of Science, Embase, and Cochrane Library. Dissertations, conference papers, and ongoing experiments will also be retrieved for supplement. Literature screening and data extraction will be completed by two authors independently (JJ and X-QW). If there were any disagreements, they would be discussed or referred to a third person for adjudication (W-ZW). Authors will use Cochrane risk of bias tool to assess the included studies. The Review Manager Statistical (RevMan) software is used to conduct the statistical process of meta-analysis, and funnel plot is used to evaluate reporting biases. The Grading of Recommendations Assessment Development and Evaluation (GRADE) Profiler can be used to be aware of the quality of evidence.

[Effect of Tongdu Tiaoshen acupuncture on serum GABA and CORT levels in patients with chronic insomnia].

OBJECTIVE: To observe the clinical effect of Tongdu Tiaoshen acupuncture on chronic insomnia, and explore its possible mechanism. METHODS: A total of 60 patients with chronic insomnia were randomly divided into an observation group (30 cases) and a control group (30 cases, 1 case dropped off ). The observation group was treated with Tongdu Tiaoshen acupuncture at Baihui (GV 20), Yintang (GV 29), Shenting (GV 24), etc. once every other day, 3 times a week. The control group was treated with estazolam tablets (1 mg) orally before going to bed every night. The treatments of both groups were required 4 weeks. The Pittsburgh sleep quality index (PSQI) scores, serum gamma-aminobutyric acid (GABA) and cortisol (CORT) levels were observed before and after treatment in the two groups, and the clinical effect was compared. RESULTS: After treatment, the sleep quality, day dysfunction scores of PSQI in the observation group and the falling asleep time, sleep time, sleep efficiency, sleep disturbance scores and total scores of PSQI in the two groups were lower than before treatment (P<0.01, P<0.05). After treatment, the daytime dysfunction score of PSQI in the observation group was lower than that in the control group (P<0.05). After treatment, the serum GABA levels in the two groups were higher than before treatment (P<0.05), and the serum CORT levels were lower than before treatment (P<0.01). The total effective rate was 90% (27/30) in the observation group and 93.1% (27/29) in the control group, the difference was not statistically significant (P>0.05). CONCLUSION: Tongdu Tiaoshen acupuncture has the same effect as western medication estazolam tablets in the treatment of patients with chronic insomnia, and has little effect on daytime dysfunction. The mechanism may be related to the increase of serum GABA level and the inhibition of the hyperactivation of hypothalamus-pituitary-adrenal (HPA) axis.

[Effect of acupuncture at Tiaoshen acupoints on hyperarousal state in chronic insomnia].

OBJECTIVE: To observe the clinical effect of acupuncture at Tiaoshen (regulating the spirit) acupoints on chronic insomnia and hyperarousal state, and explore its possible mechanism. METHODS: A total of 60 patients with chronic insomnia were randomly divided into an acupuncture group (30 cases, 1 case dropped off) and a sham acupuncture group (30 cases, 1 cases dropped off). Both groups were given basic sleep health education. The acupuncture group was treated with acupuncture at Tiaoshen acupoints including Baihui (GV 20), Shenting (GV 24), Yintang (GV 29), Shenmen (HT 7) and Sanyinjiao (SP 6). The sham acupuncture group was treated with non-effective point shallow acupuncture. Both groups were treated once every other day, 3 times a week for 4 weeks. The Pittsburgh sleep quality index (PSQI) score, pre-sleep arousal scale (PSAS) score, hyperarousal scale (HAS) score, and serum gamma-aminobutyric acid (GABA) level before and after treatment were compared between the two groups. RESULTS: Compared before treatment, the sleep quality, time to fall asleep, sleep time, sleep efficiency, sleep disturbance, daytime dysfunction scores and total score of PSQI, various scores and total score of PSAS, and HAS score in the acupuncture group after treatment were decreased (P<0.05, P<0.01); in the sham acupuncture group, the time to fall asleep, daytime dysfunction scores and total score of PSQI, and cognitive arousal score of PSAS after treatment were decreased (P<0.05). After treatment, the sleep quality, time to fall asleep, sleep time, sleep efficiency, sleep disturbance, daytime dysfunction scores and total score of PSQI, various scores and total score of PSAS, and HAS score in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). Compared before treatment, the serum GABA level in the acupuncture group were increased (P<0.05), and the serum GABA level in the acupuncture group was higher than that in the sham acupuncture group after treatment (P<0.05). CONCLUSION: Acupuncture at Tiaoshen acupoints can obviously improve the sleep and hyperarousal state of patients with chronic insomnia, and up-regulating serum GABA content is one of its possible mechanisms.

The efficacy of acupuncture on the sleep structure of patients with insomnia: A systematic review and meta-analysis.

This study aims to evaluate the efficacy of acupuncture on the sleep structure of patients with insomnia, so as to provide a valuable basis for the effectiveness of acupuncture in the treatment of insomnia. We conducted searches based on MeSH terms and free words in Cochrane Library, PubMed, Web of science, CKNI (China Knowledge Resource Integrated Database), WanFang Database, and Chongqing VIP Information from the inception of these database until 10 July 2020 for randomized controlled trials (RCTs) that investigated acupuncture treatment in patients with insomnia, and pertinent details of the results were saved. Comprehensive analysis showed that: (1) compared with the Western medicine groups, the acupuncture groups showed significant advantages in reducing the percentage of N1 sleep stage and N2 sleep stage, as well as increasing that of N3 sleep stage and REM sleep stage. However, no significant difference was found in increasing the effective rate, reducing total PSQI score, improving the total sleep time, reducing sleep latency, and improving sleep efficiency between the Western medicine groups and the acupuncture groups. (2) Compared with the sham acupuncture groups, the acupuncture treatment showed advantages in increasing the effective rate, reducing Pittsburgh Sleep Quality Index (PSQI) score, increasing the total sleep time, and improving sleep efficiency. However, no significant difference was observed between the sham acupuncture groups and the acupuncture groups with regard to reducing sleep latency, the percentage of N1 sleep stage and N2 sleep stage, as well as increasing that of N3 sleep stage and REM sleep stage.

[Effect of Tiaoshen needling on plasma melatonin and cortisol in patients with chronic insomnia].

OBJECTIVE: To observe the clinical efficacy of Tiaoshen needling (dredging Governor Vessel and regulating mind)in the treatment of chronic insomnia (CI) and its effect on plasma melatonin (MT) and cortisol (CORT) levels, so as to explore its underlying mechanism. METHODS: Sixty patients with CI were randomly divided into the treatment group and the control group, with 30 cases in each group. Both groups were given sleep hygiene education before treatment. Patients in the treatment group received acupuncture or electroacupuncture at Baihui (GV20), Shenting (GV24), Yintang (GV29), bilateral Shenmen (HT7) and Sanyinjiao (SP6). Patients in the control group received acupuncture or electroacupuncture at bilateral Shousanli (LI10), Futu (ST32) and Feiyang(BL58). Both groups were treated every other day, 3 times a week, for a total of 4 weeks. Before and after treatment, Pittsburgh sleep quality index (PSQI) and fatigue severity scale (FSS) were used to evaluate sleep qua-lity and daytime fatigue, the plasma MT and CORT levels were measured by enzyme-linked immunosorbent assay. RESULTS: Compared with before treatment, the PSQI scores and total FSS score of the treatment group decreased significantly (P<0.01，P<0.05), and the plasma MT content increased and CORT decreased significantly in the treatment group (P<0.01)，while the sleep-onset time score, sleep disturbance score and the PSQI total score of the control group decreased significantly (P<0.05). Compared with the control group, the PSQI sleep disorder score and total score, and the total FSS score as well as plasma CORT level were significantly down-regulated (P<0.01，P<0.05), while the plasma MT content was up-regulated (P<0.05) in the treatment group. CONCLUSION: Tiaoshen acupuncture can significantly improve the sleep quality of patients with CI and relieve daytime fatigue, which may be related to the increase of plasma MT content in patients with CI, thereby inhibiting the excessive activation of the hypothalamic-pituitary-adrenal axis.

[Effect of electroacupuncture on serum melatonin and dopamine in aged insomnia].

OBJECTIVE: To observe the clinical effect of electroacupuncture (EA) on aged insomnia, and explore its possible mechanism. METHODS: A total of 60 patients with aged insomnia were randomly divided into an EA group (30 cases) and a sham EA group (30 cases, 1 case dropped off). The patients in the EA group were treated with acupuncture at Baihui (GV 20), Yintang (GV 29), Shenmen (HT 7), Sanyinjiao (SP 6), Xinshu (BL 15) and Shenshu (BL 23), and EA was used at Baihui (GV 20) and Yintang (GV 29), with intermittent wave, 2 Hz in frequency. In the sham EA group, the acupoints and the EA connection acupoints were the same as those in the EA group, 2-3 mm in depth, but no current was connected. The intervention was given 30 min each time, once every other day, 3 times a week for 4 weeks in the both groups. Before and after treatment, the Pittsburgh sleep quality index (PSQI) and Montreal cognitive assessment (MoCA) scale were used to assess sleep quality and cognitive function, and serum melatonin (MT) and dopamine (DA) levels were detected. RESULTS: After treatment, the total score and sub-item scores of PSQI in the EA group were lower than those before treatment (P<0.01, P<0.05), among them, the sub-item scores of sleep quality, time to fall asleep, sleep time and sleep efficiency, daytime dysfunction and total score were all lower than those in the sham EA group (P<0.01, P<0.05). After treatment, the MoCA score and serum MT and DA levels in the EA group were higher than those before treatment (P<0.01), and the MoCA score and serum MT level in the EA group were higher than the sham EA group (P<0.01, P<0.05). CONCLUSION: Electroacupuncture can improve sleep quality and cognitive function in aged insomnia patients, and its mechanism may be related to regulating serum MT and DA levels.

[Semen cryopreservation applied to intrauterine insemination cycles for oligospermia and asthenospermia in infertile men].

OBJECTIVE: To explore the application value of semen cryopreservation in intrauterine insemination cycles for the treatment of oligospermia and asthenospermia in infertile males. METHODS: A total of 152 cycles of intrauterine insemination were performed for 103 couples with constitutional infertility, which were divided into Groups 1 (normal semen, n=53), 2 (oligospermia and asthenospermia, n=52) and 3 (fresh combined with cryopreserved semen, n=47). Semen parameters and forward motile sperm count after processing were recorded by Makler chamber, and all were followed up for the outcome of clinical pregnancy. RESULTS: Compared with Group 2, Group 3 showed obviously lower semen volume, sperm motility and grade a sperm count before semen processing, with extremely significant differences (P < 0.01), but a higher rate of grade a sperm after semen processing, though with no significant differences (P > 0.05). There were no statistically significant differences in the pregnancy rate between Groups 2 and 3 (9.6% versus 14.9%, P > 0.05). CONCLUSION: Semen cryopreservation can improve the forward motile sperm count and pregnancy rate in oligospermia and asthenospermia patients after intrauterine insemination. Semen cryopreservation combined with intrauterine insemination seems an ideal treatment for oligospermia and asthenospermia in infertile men.

[Effect of acupuncture on expression of transfer growth factor-ß1 in lacrimal gland of rabbits with dry eye].

OBJECTIVE: To observe the effect of acupuncture on expression of transforming growth factor-ß1(TGF-ß1) in lacrimal gland of rabbits with dry eye, so as to explore its underlying mechanism in improving dry eye. METHODS: Healthy male New Zealand rabbits were randomly assigned to 5 groups (n=6 in each group), namely, blank group, model group, western medicine group, acupuncture group and sham acupuncture group. The dye eye rabbit model was estabilished by subcutaneous injection of Scopolamine Hydrobromide solution for 21 days. After modeling, rabbits in the western medicine group were treated with Flumirone eye drops in their eyes 3 times a day, one drop each time. Rabbits of the acupuncture group reveived electroacupuncture(4 Hz/20 Hz, 1 mA) at "Cuanzhu"(BL2) and "Tongziliao"(GB1) for 15 min, and received acupuncture at "Jingming"(BL1), "Taiyang" (EX-HN5) and "Sizhukong"(TE23) for 15 min, once a day. Rabbits of the sham acupuncture group received blunt acupuncture at the surface of the same acupoints once a day. All the treatments were conducted for 14 days. The changes of tear flow, tear film break-up time (BUT) and lacrimal gland morphology in each group were observed. The expression of TGF-ß1 protein and mRNA in lacrimal gland were detected by Western blot and quantitative real-time fluorescence PCR respectively. RESULTS: Following modeling, except for the blank group, the tear flow and BUT in other 4 groups decreased significantly (P<0.01). Compared with their own pretreatment, the tear flow and BUT in western medicine group and acupuncture group increased after the treatment (P<0.05). Compared with the model group, the tear flow and BUT increased in the western medicine group and the acupuncture group(P<0.05). Atrophic lacrimal epithelial cells and the stroma of mucous membrane infiltrated by lymphocytes and plasma cells were found in rabbits of the model group and the sham acupuncture group. By contrast, in the western medicine group and the acupuncture group, the structure of lacrimal epithelial cells was basically normal, and the infiltration of lymphocytes and plasma cells were scattered in the stroma of mucous membrane. In comparison with the blank group, the expression of TGF-ß1 protein and mRNA in lacrimal gland were significantly up-regulated in the model and sham acupuncture groups (P<0.01). Compared with the model group, the expression of TGF-ß1 protein and mRNA were significantly down-regulated in the western medicine and acupuncture groups (P<0.01, P<0.05). CONCLUSION: Acupuncture intervention can increase tear flow and BUT in rabbits with dry eye, which may be related to the regulation of TGF-ß1 expression in lacrimal gland.

[Effect of Tongdu Tiaoshen needling in treatment of chronic insomnia by regulating the hypothalamic-pituitary-adrenal axis].

OBJECTIVE: To investigate the clinical effect of Tongdu Tiaoshen needling in the treatment of chronic insomnia and its mechanism based on the hypothalamic-pituitary-adrenal (HPA) axis. METHODS: A total of 60 patients with chronic insomnia were randomly divided into treatment group and control group, with 30 patients in each group. In addition to the health education on sleep, the patients in the treatment group were given Tongdu Tiaoshen needling, i．e., electroacupuncture at Baihui (GV20), Shenting (GV24), Yintang (EX-HN3), bilateral Shenmen (HT7), and bilateral Sanyinjiao (SP6), and those in the control group were given superficial acupuncture at Shousanli (LI10), Futu (ST32), and Feiyang (BL58) at both sides, once every other day and three times a week for 4 consecutive weeks. Before and after treatment, the Pittsburgh Sleep Quality Index (PSQI) was used to assess the quality and efficiency of sleep, and ELISA was used to measure the serum levels of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT). RESULTS: After treatment, the treatment group had significant reductions in the total PSQI score and the score of each component of PSQI (P<0.01), and the control group had significant reductions in the total PSQI score (P<0.01) and the scores of all components except sleep duration (P<0.05); compared with the control group, the treatment group had significantly lower total PSQI score and the score of each component (P<0.01). After treatment, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.05，P <0.01), and compared with the control group, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.01，P<0.05). CONCLUSION: Tongdu Tiaoshen needling has a good clinical effect in the treatment of chronic insomnia and can significantly improve the sleep condition of patients with chronic insomnia, possibly by reducing the hormones associated with the HPA axis.

[Insomnia treated with three acupuncture combinations guided by theory of Tongdu Tiaoshen: a randomized controlled trial].

OBJECTIVE: To compare the clinical therapeutic effect and safety on insomnia among three acupuncture combinations, named Tongdu Tiaowei (promoting the circulation of the governor vessel and regulating the defensive system), Tongdu Yangxin (promoting the circulation of the governor vessel and nourishing the heart) and Tongdu Tiaozang (promoting the circulation of the governor vessel and regulating zang functions). METHODS: A total of 90 patients with insomnia were randomized into a Tongdu Tiaowei group (30 cases, 1 case dropped off ), a Tongdu Yangxin group (30 cases, 2 cases dropped off ) and a Tongdu Tiaozang group (30 cases, 1 case dropped off ). Besides electroacupuncture (EA) applied to Baihui (GV 20) and Yintang (GV 29) in all of the three groups, acupuncture was added at Shenmai (BL 62) and Zhaohai (KI 6), Shenmen (HT 7) and Sanyinjiao (SP 6) as well as back-shu points of five zang organs [Feishu (BL 13), Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20) and Shenshu (BL 23)] in the Tongdu Tiaowei group, the Tongdu Yangxin group and the Tongdu Tiaozang group successively. The treatment was given once every two days, 3 times weekly, consecutively for 4 weeks. The score of Pittsburgh sleep quality index (PSQI) before and after treatment was observed, the therapeutic effect was evaluated and the adverse reactions were recorded in the patients of each group. RESULTS: After treatment, the score of each of 6 factors, named sleep quality, sleep latency, sleep time, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score of PSQI scale were all reduced as compared with the scores before treatment in the patients of each group (P<0.05). After treatment, the scores of sleep latency and daytime dysfunction in the Tongdu Tiaowei group were lower than the other two groups (P<0.05). The score of sleep time in the Tongdu Yangxin group was lower than the other two groups (P<0.05) and the score of sleep quality in the Tongdu Tiaozang group was lower than the other two groups (P<0.05). After treatment, the total effective rates were 96.6% (28/29), 96.4% (27/28) and 96.6% (28/29) in the Tongdu Tiaowei group, the Tongdu Yangxin group and the Tongdu Tiaozang group successively, without significant difference in comparison among the three groups (P>0.05). During treatment, 1 case of mild adverse reaction occurred in each group. CONCLUSION: All of the three acupuncture combinations, named Tongdu Tiaowei, Tongdu Yangxin and Tongdu Tiaozang can effectively improve the sleep conditions in the patients with insomnia and are satisfactory in safety. The acupuncture combinations of Tongdu Tiaowei has the potential advantage in shortening sleep latency and relieving daytime dysfunction, the combinations of Tongdu Yangxin has the potential advantage in increasing sleep time and the combinations of Tongdu Tiaozang has the potential advantage in improving sleep quality.

Macrophage migration inhibitory factor promotes colorectal cancer.

A growing body of evidence implicates macrophage migration inhibitory factor (MIF) in tumorigenesis and metastasis. In this study, we investigated whether MIF expression was associated with clinicopathologic features of colorectal carcinoma (CRC), especially in tumors with hepatic metastasis, and whether neutralization of endogenous MIF using anti-MIF therapeutics would inhibit tumor growth and/or decrease the frequency of colorectal hepatic metastases in a mouse colon carcinoma model. The concentration of serum MIF was positively correlated with an increased risk of hepatic metastasis in human patients with CRC (R = 1.25, 95% confidence internal = 1.02-1.52, P = 0.03). MIF was also dramatically upregulated in human colorectal tissue, with 20-40 times as many MIF-positive cells found in the mucosa of patients with CRC than in normal tissue (P < 0.001 ANOVA). Moreover, in those patients with metastatic colorectal cancer in the liver, MIF-positive cells were similarly increased in the diseased hepatic tissue. This increased MIF expression was restricted to diseased tissue and not found in areas of the liver with normal morphology. In subsequent in vitro experiments, we found that addition of recombinant MIF to colonic cell lines significantly increased their invasive properties and the expression of several genes (for example, matrix metalloproteinase 9 and vascular endothelial growth factor) known to be upregulated in cancerous tissue. Finally, we treated mice that had been given CT26 colon carcinoma cell transplants with anti-MIF therapeutics--either the MIF-specific inhibitor ISO-1 or neutralizing anti-MIF antibodies--and observed a significant reduction in tumor burden relative to vehicle-treated animals. Taken together, these data demonstrate that MIF expression was not only correlated with the presence of colorectal cancer but also may play a direct role in cancer development.
