Establishment and evaluation of a nomogram model of systemic inflammatory response syndrome after percutaneous nephrolithotomy / 医学研究生学报

Objective The main cause of systemic inflammatory response syndrome(SIRS) after percutaneous nephrolithotomy(PCNL) was still unclear. The purpose of this study was to investigate the risk factors associated with SIRS after PCNL and establish the nomogram model. Methods A retrospective analysis of 213 cases of PCNL patients due to upper urinary calculi admitted to urology department in affiliated hospital of guilin medical college from December 2017 to December 2018 was performed. According to the occurrence of SIRS, patients were divided into SIRS group (SIRS patients) and control group (patients without SIRS). Logistic regression was used to analyze the risk factors of SIRS after PCNL, and a nomogram model was established based on logistic regression model. Results There were 54 cases in the SIRS group and 159 in the control group. Gender(OR=2.547, 95%cl:1.229-5.275), diabetes (OR=5.027, 95%cl: 1.442-17.525), calculi surface area (OR=2.657, 95%cl: 1.206-5.853), NLR immediately after surgery (OR=3.793, 95%cl: 1.749-8.02), operation time (OR=2.985, 95%cl: 1.305-6.826), and blood transfusion (OR=12.50, 95%cl: 12.50). 1.954-80.056) were the risk factors of SIRS after PCNL (P<0.05). Based on the results of the logistic multi-factor regression model mentioned above, visualized display of the model was achieved by using column and diagram. As the NLR ratio, operation time and stone surface area increased immediately after the operation, the score gradually increased, and the risk of SIRS gradually increased. The nomogram model established according to logistic regression model has good differentiation and model consistency (c-index =0.791). Conclusion According to the risk factors, such as gender, diabetes history, stone surface area, immediate postoperative NLR, the constructed nomogram model has good predictive efficacy, which is of guiding significance for clinical practice.

Comparative study of heat-sensitive moxibustion in the treatment of knee osteoarthritis / 中国针灸

<p><b>OBJECTIVE</b>To verify the clinical efficacy of heat-sensitive moxibustion in treatment of knee osteoarthritis (KOA).</p><p><b>METHODS</b>Sixty cases of KOA were randomly divided into a heat-sensitive moxibustion group and a conventional moxibustion group, 30 cases in each one. Dubi (ST 35), Yanglingquan (GB 34), Zusanli (ST 36) and Heding (EX-LE 2) on the affected side were selected in two groups. In heat-sensitive moxibustion group, the techniques of circling moxibustion, sparrow-pecking moxibustion, moving moxibustion and mild moxibustion were applied. In conventional moxibustion group, the mild moxibustion was used, 2 to 3 cm far from the skin of the acupoints selected. Lysholm scale for the assessment of knee joint function was adopted to evaluate the efficacy. The scores of joint pain, morning stiffness, joint swelling and walking ability were compared before and after treatment in two groups.</p><p><b>RESULTS</b>The scores of joint pain, morning stiffness, joint swelling and walking ability after treatment were all apparently improved as compared with those before treatment in either group (all P < 0.05). The improvement in the above-mentioned indices in heat-sensitive moxibustion group was much more apparent as compared with that in conventional moxibustion group (all P < 0.01). The effective rate was 90.0% (27/30) in heat-sensitive moxibustion group and was 73.3% (22/30) in conventional moxibustion group. The effective rate in heat-sensitive moxibustion group was obviously superior to that in conventional moxibustion group (P < 0.01).</p><p><b>CONCLUSION</b>The efficacy of heat-sensitive moxibustion is superior to that of conventional moxibustion in the treatment of KOA. This therapy can more significantly improve the symptoms and physical signs of the patients with KOA.</p>

Correlation between the liver meridian and the frontal lobe in depression by needling at taichong (LV3): a resting-state fMRI study / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the mechanism of depression treatment by needling at Taichong (LV3) and the correlation between the liver meridian and the frontal lobe.</p><p><b>METHODS</b>Forty-two patients with moderate depression at the first attack in line with Diagnostic and Statistical Manual of Mental Disorders (4th ed) by American Psychiatric Association were assigned to the fluoxetine group, the needling + fluoxetine group, and the needling group, 14 in each. The therapeutic course for them all was one month. Resting fMRI scanning was performed before and after treatment using 3.0 T magnetic resonance. Data were analyzed using fractional amplitude of low frequency fluctuations (fALFF). Paired t-test was used for comparison. Correlation analysis was performed in the fALFF images after treatment and Hamilton's depression scale.</p><p><b>RESULTS</b>Compared with before treatment, fALFF values in the left frontal lobe (BA6, BA9, BA48), the right frontal lobe (BA4, BA46), the bilateral inferior parietal lobules (BA40, BA48), the precuneus (BA7), the posterior cingutate (BA31), the left occipital lobe (BA17), and the right occipital lobe (BA18) of the needling +fluoxetine group were lowered (P<0.05). fALFF values in the right inferior parietal lobule (BA40) and the right occipital lobe (BA17) of the fluoxetine group were lowered (P<0.05). fALFF values in the left frontal lobe (BA10), the right frontal lobe (BA45), the left occipital lobe (BA19), the right occipital lobe (BA17), the left precuneus (BA7), and the posterior cingutate (BA31) were lowered in the needling group (P<0.05). Hamilton's depression scale was positively correlated with the fALFF value in the left frontal lobe of the needling +fluoxetine group and the needling group, while Hamilton's depression scale was positively correlated with the fALFF value in the left middle frontal gyrus, the left parietal lobe, and the left occipital lobe in the fluoxetine group.</p><p><b>CONCLUSIONS</b>Combination of needling and antidepressive agents was superior to needling or antidepressive agents alone. Changes of the frontal lobe functions were correlated with the severity of depression. More extensive correlation existed between the liver meridian and the frontal lobe, which might be the antidepressive mechanism of needling Taichong (LV3).</p>

Study on corresponding areas the liver and lung channels in brain with fMRI / 中国针灸

<p><b>OBJECTIVE</b>To explore distribution of the Liver and Lung Channels in the brain so as to provide imaging basis for construction of channel theory in the brain.</p><p><b>METHODS</b>Sixty healthy student volunteers were randomly divided into a Liver Channel group (I) and a Lung Channel group (II), and the each group was further divided into five subgroups with 6 volunteers in each subgroup, based on five-shu-point principles which, were Dadun (LR 1, I 1), Xingjian (LR 2, I 2), Taichong (LR 3, I 3), Zhongfeng (LR 4, I 4), Ququan (LR 8, I 5), Shaoshang (LU 11, II 1), Yuji (LU 10, II 2), Taiyuan (LU 9, II 3), Jingqu (LU 8, II 4), and Chize (LU 5, II 5), respectively. In order to observe the brain activating patterns during acupuncture at the different acupoints, functional magnetic resonance imaging (fMRI) technique was adopted. All image data were then analyzed with SPM 2 software. The statistical parameter gram was composed of the pixel P < 0.01, and anatomic location was made according to Talairach coordinate, attaining experimentally activated areas, and the commonly activated area of five-shu-point of each channel was considered as the brain distribution of the Liver and Lung Channels.</p><p><b>RESULTS</b>The common areas activated by the five-shu-points of the Liver Channel were homolateral Brodmann area (BA) 34, BA 47, red nucleus, contralateral BA 19, BA 30, BA 39, the superior parietal lobule, cerebellum decline, and bilateral BA 3 and culmen. The common areas activated by the five-shu-points of the Lung Channels included homolateral BA 2, BA 18, BA 35, and contralateral BA 9 and substania nigra.</p><p><b>CONCLUSION</b>There are relatively specific corresponding brain areas for the Liver and Lung Channels, indicating that there is possible relatively specific connection between channels and the brain.</p>

Hypothesis on "all the 12 channels entering the brain" / 中国针灸

Out of the 20 channels in the channel and collateral system, only 5 enter the brain, with unclear circulation pathway in the brain. Electrophysiologic and imaging studies indicate that the signal induced by acupuncture at acupoints can enter the brain no matter whether the channel connecting the acupoint enters the brain. Therefore, the authors put forward the hypothesis of "all the 12 channels enter the brain", i.e., the hypothesis of "channels and collaterals in brain". In the theory system of channels, less channels enter the brain with unclear circulation pathway. This possibly is related with that sensation is main way for descovery of channels. In future, we should adopt modern scientific and technical ways and strengthen the study on circulation of channels in the brain, so as to perfect the channel theory.

A quantitative study of the relationship between levels of liver fibrosis markers in sera and fibrosis stages of liver tissues of patients with chronic hepatic diseases / 中华肝脏病杂志

<p><b>OBJECTIVES</b>To study the quantitative relationship between the levels of serum liver fibrosis markers and fibrosis stages of liver tissues in patients with chronic hepatic diseases.</p><p><b>METHODS</b>In 118 patients with chronic hepatitis, fatty liver or cirrhosis, their Serum levels of LN, HA, PCIII and CIV were investigated by EIA and their liver histological changes were studied. The relationship between the levels of serum LN, HA, PCIII and CIV and the degrees of liver tissue fibrosis was analyzed quantitatively by using the SPSS11.0.</p><p><b>RESULTS</b>A correlation between the levels of serum LN, HA, PCIII and CIV and the histologically assessed grades of inflammatory activity was found (r = 0.394, 0.449, 0.443, 0.351, respectively, P <0.01). The correlation between the levels of serum LN, HA, PCIII and CIV and the histological assessed stages of liver fibrosis was strong (r = 0.456, 0.564, 0.476, 0.421 respectively, P <0.01). The levels of serum LN, HA, PCIII and CIV of the patients with a stage 2 liver fibrosis were 110 ng/ml, 110 ng/ml, 100 ng/ml and 70 ng/ml respectively, with sensibilities of diagnosing stage 2 liver fibrosis at 70%, 79%, 79% and 74% respectively. Their specificities in diagnosing stage 2 liver fibrosis were 68%, 72%, 64% and 73% respectively. The levels of LN, HA, PCIII and CIV in serum of these patients diagnosing cut-off value in stage 4 liver fibrosis (early cirrhosis) were 130 ng/ml, 140 ng/ml, 120 ng/ml and 70 ng/ml respectively. Their sensibility of diagnosing liver cirrhosis was 79%, 93%, 79% and 86% respectively. Their specificity of diagnosing liver cirrhosis was 66%, 82%, 72% and 61% respectively. As shown by the ROC curves in these patients, differentiating patients with cirrhosis or without cirrhosis, serum HA level was more valuable than LN, PCIII, CIV (the areas under the curves = 0.938 vs 0.775, 0.787, 0.791 ) When serum HA was higher than 190 ng/ml, the veracity of diagnosing liver cirrhosis was 93%.</p><p><b>CONCLUSIONS</b>There is a certain quantitative relationship between the levels of LN, HA, PCIII and CIV in serum and the degrees of liver tissue fibrosis. The level of HA in serum is an important reference datum for early diagnosing liver cirrhosis.</p>
