Exploring the causal relationship between immune cell and all-cause heart failure: a Mendelian randomization study.

Background and objectives: Heart failure (HF) is a disease with numerous genetic and environmental factors that affect it. The results of previous studies indicated that immune phenotypes are associated with HF, but there have been inconclusive studies regarding a causal relationship. Therefore, Mendelian randomization (MR) analyses were undertaken to confirm the causal connections between immune phenotypes and HF, providing genetic evidence supporting the association of immune cell factors with HF risk. Methods: We selected instrumental variables that met the criteria based on data from the results of genome-wide association studies (GWAS) of immune phenotype and all-cause HF. An evaluation of the causal association between 731 immune cell factors and HF risk was carried out using the inverse variance weighted (IVW), MR-Egger regression (MR-Egger), and weighted median (WM) analysis methods. To determine the horizontal pleiotropy, heterogeneity, and stability of the genetic variants, the MR-Egger intercept test, Cochran's Q test, MR-PRESSO, and leave-one-out sensitivity analysis were performed. Results: MR principal method (IVW) analysis showed that a total of 38 immune cell-related factors were significantly causally associated with HF. Further analyses combining three methods (IVW, MR-Egger and WME) showed that six exposure factors significantly associated with heart failure, as shown below. The effect of Dendritic cell Absolute Count, CD62l- CD86+ myeloid Dendritic cell Absolute Count, CD62l- CD86+ myeloid Dendritic cell% Dendritic cell, CD39+ CD8+ T cell% CD8+ T cell, CD3 on Central Memory CD4+ T cell on heart failure was positive. Whereas, a reverse effect was observed for CD14+ CD16+ monocyte% monocyte. Conclusion: We investigated the causal relationship between immune phenotypes and all-cause HF. According to the results, Dendritic cell Absolute Count, CD62l- CD86+ myeloid Dendritic cell Absolute Count, CD62l- CD86+ myeloid Dendritic cell% Dendritic cell, CD39+ CD8+ T cell% CD8+ T cell, CD3 on Central Memory CD4+ T cell aggravate HF, and the risk of HF is decreased by CD14+ CD16+ monocyte% monocyte. These phenotypes may serve as new biomarkers, providing new therapeutic insights for the prevention and treatment of all-cause HF.

Risk factors and a predictive model for the occurrence of adverse outcomes in patients with new-onset refractory status epilepsy.

Objectives: To determine risk factors for the occurrence of adverse outcomes in patients with new-onset refractory status epilepsy (NORSE) and to construct a concomitant nomogram. Methods: Seventy-six adult patients with NORSE who were admitted to the Department of Neurology, First Affiliated Hospital of Sun Yat-sen University between January 2016 and December 2022 were enrolled for the study. Participants were divided into two-those with good and poor functional outcomes-and their pertinent data was obtained from the hospital medical recording system. Univariate analysis was used to identify potential causes of poor outcomes in both groups and a multivariate logistic regression model was used to identify risk factors for the occurrence of poor outcomes. Using the R programming language RMS package, a nomogram was created to predict the occurrence of poor outcomes. Results: The NORSE risk of adverse outcome nomogram model included four predictors, namely duration of mechanical ventilation (OR = 4.370, 95% CI 1.221-15.640, p = 0.023), antiviral therapy (OR = 0.045, 95% CI 0.005-0.399, p = 0.005), number of anesthetics (OR = 13.428, 95% CI 2.16-83.48, p = 0.005) and neutrophil count/lymphocyte count ratio (NLR) (OR = 5.248, 95% CI 1.509-18.252, p = 0.009). The nomogram had good consistency and discrimination in predicting risk and can thus assist clinical care providers to assess outcomes for NORSE patients. Through ordinary bootstrap analyses, the results of the original set prediction were confirmed as consistent with those of the test set. Conclusion: The nomogram model of risk of adverse outcomes in NORSE adult patients developed in this study can facilitate clinicians to predict the risk of adverse outcomes in NORSE patients and make timely and reasonable interventions for patients at high risk of adverse outcomes.

Thymoma-associated autoimmune encephalitis with myasthenia gravis: Case series and literature review.

OBJECTIVES: This comprehensive review aimed to compile cases of patients with thymoma diagnosed with both autoimmune encephalitis (AE) and myasthenia gravis (MG), and describe their clinical characteristics. METHODS: Clinical records of 3 AE patients in the first affiliated hospital of Sun Yat-sen University were reviewed. All of them were diagnosed with AE between 1 November 2021 and 1 March 2022, and clinical evidence about thymoma and MG was found. All published case reports were searched for comprehensive literature from January 1990 to June 2022. RESULTS: A total of 18 cases diagnosed with thymoma-associated autoimmune encephalitis (TAAE) and thymoma-associated myasthenia gravis (TAMG) were included in this complication, wherein 3 cases were in the first affiliated hospital of Sun Yat-sen University and the other 15 were published case reports. 5/18 patients had alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor antibody (AMPAR-Ab) in their serum and cerebrospinal fluid (CSF). All of them had positive anti-acetylcholine receptor antibody (AChR-Ab). And 12/18 patients showed a positive response to thymectomy and immunotherapy. Besides, thymoma recurrences were detected because of AE onset. And the shortest interval between operation and AE onset was 2 years in patients with thymoma recurrence. CONCLUSIONS: There was no significant difference in the clinical manifestations between these patients and others with only TAMG or TAAE. TAAE was commonly associated with AMPAR2-Ab. Significantly, AE more commonly heralded thymoma recurrences than MG onset. And the intervals of thymectomy and MG or AE onset had different meanings for thymoma recurrence and prognoses of patients.

Carboxymethylcellulose hydrogels with stable carbon quantum dots: Enabling dynamic fluorescence modulation, automatic erasure, and secure information encryption.

Inspired by "disappear after reading", a time-modulated encryption hydrogel was synthesized by carboxymethyl cellulose with carbon quantum dots. Carboxymethyl cellulose in this system stabilized carbon quantum dots, which ensured the whole hydrogel worked well. The encryption/decryption of information depended on pH adjustment, application of EDTA and Cr (VI). Furthermore, an in-depth analysis of the fluorescence change mechanism uncovered that fluorescence quenching was potentially influenced by internal filtering effects and static quenching, which involved the amino, carboxyl, and hydroxyl groups present within the hydrogel.

Multifunctional Organohydrogels for pH-Responsive Fluorescent and Electrostimulus Writing.

Hydrogels have attracted widespread attention in anticounterfeiting due to their unique physical/chemical properties and designability. However, hydrogels' poor mechanical properties and sluggish response to chemical stimuli pose challenges for their wide application. A fluorescent tough organohydrogel capable of freeform writing of information is reported in this work. By incorporation of the fluorescent monomer 7-methylacryloxy-4-methylcoumarin into the polyacrylamide network in a covalently cross-linked manner while intertwining with the carboxymethyl cellulose sodium network, a fluorescent tough organohydrogel with a dual-network structure is prepared. The organohydrogel shows acid-base-mediated adjustable fluorescence through the transformation of fluorescent monomers. Ion printing and electrical stimulation design achieved free information storage and encryption. In addition, the prepared organohydrogel has good antifreezing properties and can be encrypted and decrypted at subzero temperatures. The encrypted information in the organohydrogel can be read only after UV-light irradiation. These patterned fluorescent organohydrogels should find applications in protected message displays for improved information security.

Causal associations of 25-hydroxyvitamin D with functional gastrointestinal disorders: a two-sample Mendelian randomization study.

BACKGROUND: Previous observational studies have shown associations between vitamin Ds and FGIDS[Including irritable bowel syndrome(IBS) and functional dyspepsia(FD)]. However, the association is controversial and the causality remains unknown. In this study, two-sample MR was cited to explore the causal effect on FGIDS caused by vitamin D level and serum 25-hydroxyvitamin D. METHOD: The GWASs of vitaminD and 25-hydroxyvitamin D, with 57-99 strongly related SNPs were all obtained from UK biobank. The GWASs of IBS and FD were obtained from FinnGen biobank with respectively 187,028 and 194,071 participants involved. Fixed-effect inverse variance weighted regression was used to evaluate causal estimates. Other statistical methods such as MR Egger, weighted median estimation, maximum likelihood estimation and penalty-weighted median estimation are also used to verify the accuracy of the main results. RESULTS: Measuring by the IVW method, our research indicated that no causal relationship was detected between vitamin D intake and Functional gastrointestinal disorders [IVW, OR(vitamin D-IBS) = 0.909, 95% CI 0.789-1.053, p = 0.2017); OR(vitamin D-FD) = 1.0662, 95% CI 0.9182-1.2380, p = 0.4000]. As for serum 25-hydroxyvitamin D, no causal relationship was detected on FD(IVW, OR(25-hydroxyvitamin D-FD) = 0.9635, 95% CI 0.8039-1.1546, p = 0.6869). Nevertheless, a negative causal relationship was revealed between 25-hydroxyvitamin D and IBS(IVW, OR(25-hydroxyvitamin D-IBS) = 0.832, 95% CI 0.696-0.995, p = 0.0436). Sensitive analysis supported the main findings but did not suggest bias due to pleiotropy. CONCLUSIONS: Our Mendelian randomization analyses suggest a negative causal relationship between 25-hydroxyvitamin D and IBS. For each additional SD increase of genetically determined 25-hydroxyvitamin D levels, the risk of IBS decreased by 16.8%.

mNGS facilitates the accurate diagnosis and antibiotic treatment of suspicious critical CNS infection in real practice: A retrospective study.

Whether metagenomic next-generation sequencing (mNGS) could benefit patients with suspected severe central nervous system (CNS) infection in terms of diagnosis and antibiotic treatment remains unknown. We retrospectively analyzed 79 patients with suspected CNS infection and undertook mNGS. The value of mNGS was investigated in terms of identification of pathogen and guidance for the adjustment of antibiotic treatment. The relationship between the time of initiating mNGS since onset and the Glasgow Outcome Scale (GOS) score after 90-day follow-up were analyzed. Fifty out of 79 cases with suspicious severe CNS infection were finally diagnosed. Despite previous routine laboratory tests, mNGS further promoted the accurate identification of pathogens in 23 cases (47.9%). The sensitivity, specificity, and accuracy of mNGS test in this study were 84.0, 79.3, and 82.3%, respectively. Furthermore, mNGS facilitated the adjustment of empirical antibiotic treatments in 38 cases (48.1%). The time of taking mNGS since onset had an insignificant weak positive correlation with GOS after 90-day follow-up (r = -0.73, P = 0.08). mNGS facilitated the accurate identification of pathogens in suspicious severe CNS infections and promoted the accurate antibiotic therapy even empirical antibiotics were administrated. It should be taken as early as possible to improve the clinical outcome of patients with suspicious severe CNS infection.

Gut Microbiota and Metabolites in Atrial Fibrillation Patients and Their Changes after Catheter Ablation.

The gut microbiota has been shown to be associated with multiple cardiovascular diseases, but there is little research on the gut microbiota and atrial fibrillation (AF); thus, how the gut microbiota and metabolites change in AF patients after catheter ablation is unclear. In this study, we used 16S rRNA high-throughput sequencing and nontargeted metabolomic detection to conduct horizontal and longitudinal analyses of the gut microbiota and metabolites of AF patients. Compared with a control group, species richness and diversity increased significantly in AF patients. Among them, opportunistic pathogenic bacteria, such as Klebsiella, Haemophilus, Streptococcus, and Enterococcus, were significantly increased, and symbiotic bacteria, such as Agathobacter and Butyrivibrio, were significantly reduced. After catheter ablation, intestinal symbiotic bacteria (Lactobacillus, Agathobacter, Lachnospira, etc.) were increased in most AF patients, while pathogenic bacteria (Ruminococcus, etc.) were reduced. Moreover, in AF patients, caffeine, which was negatively correlated with Klebsiella, was downregulated, and estradiol and ascorbic acid, which were positively correlated with Agathobacter, were also downregulated. After catheter ablation, citrulline, which was positively correlated with Ralstonia and Lactobacillus, was increased. Oleanolic acid, which was negatively correlated with Ralstonia was downregulated. In conclusion, our results not only show overall changes in the gut microbiota and metabolites in AF patients but also indicate their changes in the short term after catheter ablation. These data will provide novel possibilities for the future clinical diagnosis and treatment of AF. IMPORTANCE Gut microbiota and metabolites play a very important role in human health and can not only assess human health but also treat and prevent diseases. We analyzed the characteristics of the microbiota and metabolites in the human gut and found the effect of disease on gut microbiota and metabolites, which may be of important value in the pathogenesis of atrial fibrillation. At the same time, we also observed dynamic changes in gut microbiota and metabolites with the intervention of catheter ablation, which was not available in previous studies.

Simulation of the temporal resolution uniformity of a dilation framing camera.

The temporal resolution uniformity of a time-dilation framing camera is studied, and the ideal photocathode (PC) pulse curve is determined, while the temporal magnification factor is kept constant. To obtain the ideal curve, a series of linear pulses with the same slope are superposed. The variance in the temporal resolution and the number of linear pulses required are compared, while the superposition results with different slopes are used as the PC voltage. As the slope of the linear pulses decreases, the variance decreases, which means that the uniformity of the temporal resolution is improved, but the number of linear pulses required increases. In this study, linear pulses with a slope of 1 V/ps are superposed. Nine linear pulses with a front edge time of 200 ps, amplitude of 200 V, and flat top time of 1 ns are superimposed to approximate the ideal PC pulse curve with a constant temporal magnification factor of 10; the trigger times of the pulses are 0, 0, 0, 185, 200, 350, 450, 605, and 790 ps. When the superposition result is applied as the PC voltage and the measured signal is synchronized to the PC pulse at 128 ps-1 ns, the temporal resolution error is within 5%.

Fluorescent wood with non-cytotoxicity for effective adsorption and sensitive detection of heavy metals.

Heavy metal pollution is one of the primary challenges of water pollution, and the fabrication of highly effective, green and non-toxic adsorbents for heavy metals is urgently required on the basis of environmental and sustainable development strategies. Here, we report a novel fluorescent wood (FW) with effective adsorption ability (maximum theoretical adsorption capacity of 98.14 mg/g for hexavalent chromium [Cr(VI)]), good fluorescence properties (absolute quantum yield of 12.8%), non-cytotoxicity (cell viability of >90%) and high detection sensitivity and selectivity for Cr(VI). The FW was formed using a process involving delignification, infiltration with carbon dots, and free-radical polymerization with acrylic acid. Mechanistic analysis confirmed that the reconstructed 3D porous structure of the FW provided many effective sorption sites, such as amino, hydroxyl and carboxyl groups. This improved the adsorption ability and stabilized the fluorescence signal, which enhanced the detection ability. These factors give the novel FW considerable potential for use in the removal of Cr(VI) ions from wastewater.

Effect of terbutaline plus doxofylline on chronic obstructive pulmonary disease.

OBJECTIVES: This study focused on patients with chronic obstructive pulmonary disease (COPD) and aimed at investigating the effect of terbutaline plus doxofylline on their pulmonary function and quality of life. METHODS: Ninety COPD patients were divided by using a random number table into a control group (administration of doxofylline) and experimental group (administration of terbutaline combined with doxofylline), with 45 patients in each group. The therapeutic efficacy, pre- and post-treatment pulmonary function and the quality of life were compared between the control and experimental groups. RESULTS: After treatment, patients in the experimental group had lower levels of interleukin-8, tumor necrosis factor α and C-reactive protein (all P<0.001), higher forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEVl/FVC (all P<0.001), and lower total score of COPD assessment test (P<0.05) compared with the control group. CONCLUSION: Terbutaline combined with doxofylline for the treatment of COPD patients can efficiently decrease inflammatory factor levels, and bring them better pulmonary function and quality of life.

Novel fluorescent lignin-based hydrogel with cellulose nanofibers and carbon dots for highly efficient adsorption and detection of Cr(VI).

A novel fluorescent lignin-based hydrogel with cellulose nanofibers and carbon dots (CDs) was synthesized for the high-value utilization of lignin and control of hexavalent chromium (Cr(VI)). Its chemical and physical structure was characterized, and its Cr(VI) sorption performance was evaluated. The results demonstrated that 3D porous structures were constructed in this hydrogel. The maximum adsorption capacity of this hydrogel was 599.9 mg/g, and its sorption performance met Freundlich and pseudo-second-order models. Meanwhile, this novel hydrogel exhibited high sensitivity to Cr(VI), with a limit of detection of 11.2 mg/L and a wide linear range from 15 to 200 mg/L. Moreover, its mechanism for efficiently adsorbing and detecting Cr(VI) was analyzed. The results confirmed that the efficient adsorption and detection were due to these 3D porous structures generated by the lignin and cellulose nanofibers modified with CDs. The porous structures provided many active sites and ion transport channels, thereby improving the adsorption, and stabilized the fluorescence signal, thus enhancing the detection.

A 3D porous fluorescent hydrogel based on amino-modified carbon dots with excellent sorption and sensing abilities for environmentally hazardous Cr(VI).

To effectively detect and remove environmentally hazardous Cr(VI), a novel 3D porous fluorescent hydrogel was synthesised using amino-modified carbon dots and cellulose nanofibers. The synthesised fluorescent hydrogel was characterized to determine its morphology, crystalline structure, chemical composition and optical property using scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, UV-vis absorption spectroscopy and photoluminescence spectroscopy. The sorption properties of the synthesised fluorescent hydrogel were further analyzed. The maximum sorption capacity for Cr(VI) reached 534.4 mg/g, the adsorption isotherm was well fitted using Langmuir model, and the adsorption kinetics were well fitted using a pseudo-second-order model. The sensing ability of the synthesized hydrogel for Cr(VI) was also determined. Furthermore, the mechanism of Cr(VI) sorption and sensing was determined. Accordingly, this novel 3D porous fluorescent hydrogel was identified to be a promising sorbent with advantages of excellent sorption and sensing abilities for environmentally hazardous Cr(VI).

Adsorption of dichromate ions from aqueous solution onto magnetic graphene oxide modified by ß-cyclodextrin.

In this work, the ß-cyclodextrin modified magnetic graphene oxide (ß-CD/MGO) composite was fabricated by the in situ co-precipitation method and characterized by Fourier transform-infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), vibrating sample magnetometer (VSM), and particle size analysis. The adsorption behavior of dichromate ions on the ß-CD/MGO was investigated, and the mechanism of adsorption was also studied using FT-IR and XPS. The results from SEM and TEM showed that the graphene oxide (GO) layer became rough, and many fine particles were attached after compounding with ferroferric oxide and ß-cyclodextrin. The characterization results of FT-IR and XPS show that that ß-cyclodextrin and ferroferric oxide have been perfectly compounded to the graphene oxide layer and ß-CD/MGO has a particle size of about 460 nm, a specific surface area of 252.3 m2g-1, and a saturation magnetization of 73.5 emu g-1. The adsorption amount of dichromate ions on the ß-CD/MGO is affected by pH, adsorbent dosage, and adsorption time. Kinetic studies showed that the adsorption process followed a pseudo-second-order kinetic model. Equilibrium data agreed very well with the Langmuir model, the maximum adsorption amount of dichromate ions on the ß-CD/MGO was 49.95 mg g-1. After five successive adsorbent reuses, the reuse rate is still 73%, indicating the excellent potential reusability of ß-CD/MGO adsorbent. ß-CD/MGO exhibits excellent adsorption performance for dichromate ions. As an environmentally friendly magnetic adsorbent, ß-CD/MGO is suitable for the treatment of dichromate-containing wastewater.

High accuracy of quantitative fluorescence polymerase chain reaction combined with non-invasive pre-natal testing for mid-pregnancy diagnosis of common fetal aneuploidies: A single-center experience in China.

Quantitative fluorescence polymerase chain reaction (QF-PCR) may be used as a mid-pregnancy test to confirm the diagnosis of common fetal aneuploidies, but its use is controversial. The present study aimed to determine the value of QF-PCR for diagnostic confirmation of karyotyping and the impact of parental origin and meiosis stage on the detected aneuploidy. The present prospective cohort study included pregnant women (age, 21-45 years; gestational age, 17-25 weeks) who consulted between May 2015 and December 2016. Women were screened and only consecutive high-risk individuals were included (n=428). QF-PCR analysis of amniocytes was performed. Karyotype analysis was considered the gold standard. Parental karyotyping was performed if the embryo exhibited any aneuploidy. GeneMapper 3.2 was used for data analysis. There were no false-negative or false-positive QF-PCR results, with 100% concordance with the karyotype. The aneuploidy distribution (n=105) was 68.6% for trisomy 21, 19.0% for trisomy 18, 7.6% for sex chromosome aneuploidy, 3.8% for trisomy 13 and 1.0% for 48,XXX,+18. Regarding trisomy 21, most cases (86.1%) were of maternal origin, 8.3% paternal and 6.5% undefined. Trisomy 18 was 88.2% maternal and 11.8% paternal. Maternal meiosis stage errors in trisomy 21 mainly occurred in meiosis I, while the origin of trisomy 18 exhibited similar proportions between meiosis I and II. The combination of non-invasive pre-natal testing and QF-PCR may become a rapid and effective method for fetal aneuploidy detection. QF-PCR may provide more genetic information for clinical diagnosis and treatment than karyotyping alone.

Lycium barbarum (Wolfberry) Increases Retinal Ganglion Cell Survival and Affects both Microglia/Macrophage Polarization and Autophagy after Rat Partial Optic Nerve Transection.

The rat partial optic nerve transection (PONT) model has been used for studying secondary degeneration of retinal ganglion cells (RGCs) in recent years. In this study, we carried out PONT of the temporal side of rat optic nerves, whereas PONT was carried out of the superior side in the previous publication. We found that this surgery is better and easier than the previous method and can produce a repeatable and reliable model. We detected significant changes in the polarization of microglia/macrophages and the level of autophagy in optic nerves after PONT. We also used this model to detect the effects of the polysaccharides extracted from Lycium barbarum (LBP) on the survival of RGCs and the changes in the polarization of microglia/macrophages and the level of autophagy after PONT. We find that LBP can delay secondary degeneration of RGCs after temporal injury of optic nerves, promote the M2 polarization of microglia/macrophages, and down-regulate the level of autophagy after PONT. In conclusion, we find that the polarization of microglia/macrophages and the autophagy level change after PONT; LBP treatment delays secondary degeneration of RGCs; and the polarization of microglia/macrophages and the level of autophagy are also altered after LBP treatment.

The fluorescence spectra reveal that it shows an emission band in the red region. The fluorescence lifetime is 39 µsec and the quantum yield is 1.7%. The cyclic voltammetry (CV) measurement revealed one quasi-reversible wave with E1/2 = 0.30 V.

[Clinical efficacy on mental retardation in the children treated with JIN's three scalp needling therapy and the training for cognitive and perceptual disturbance].

OBJECTIVE: To explore the impacts on the cognitive level of the children with mental retardation (MR) treated with JIN's three scalp needling therapy and the training for cognitive and perceptual disturbance so as to seek the more effective therapeutic method for the treatment of MR in children. Methods Sixty-six MR children were randomized into a head-point needle-retaining therapy + training group (group A) and a training after acupuncture group (group B). Seven cases and 12 cases were dropped in the two groups respectively. Twenty-six cases accomplished the treatment in the group A and 21 cases in the group B. In the group A, the points on the head were stimulated and the needles were retained (30 min after the general acupuncture, the needles on the body points were removed; and those on the head points were retained for 1 h, including Sishenzhen, Naosanzhen, Zhisanzhen and Niesanzhen). Simultaneously, the training for the cognitive perceptual disturbance was combined. In the group B, 1 h after needle retaining at the body points and head points, all the needles were removed; the training for the cognitive perceptual disturbance was followed. The treatment was given once a day, and the treatment for 3 months was required. Before and after treatment, the Wechsler intelligence scale for children (WISC) was used for evaluation and observation of verbal intelligence quotient (VIQ) , performance intelligence quotient (PIQ) and full-scale intelligence quotient (TFIQ) and score changes of 11 items such as information, picture vocabu; lary, arithmetic, picture generalization, comprehension, etc. RESULTS: After treatment, FIQ, VIQ and PIQ scores were different significantly as compared with those before treatment (all P<0. 01). In the group A, the results of picture vocabulary, animal egg laying, maze, block design and geometric figure were all improved significantly (all P<0. 05). In the group B, the results of information, comprehension, block design and geometric figure were all improved significantly (all P<0. 05). After treatment, concerning the value difference in FIQ and PIQ of the two groups; the changes in the group A were more significant (both P<0. 01). After treatment, the results of picture vocabulary and maze were improved significantly in the group A as compared with the group B (both P<. 01). The IQ categories changed apparently after treatment in the two groups, toward the higher level in tendency generally, but without significant difference (both P>0. 05). CONCLUSION: The simultaneous treatment with head point retaining of JIN's three needling therapy and the training for cognitive and perceptual disturbance obviously improves children patients' verbal comprehension, expression ability, hand-eye coordination ability, attention, logical reasoning ability and visual perception. The efficacy is better than that in the treatment of the training after acupuncture.

[Efficacy observation on Jin's three-needle therapy for allergic rhinitis of lung qi deficiency and cold syndrome].

OBJECTIVE: To compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication. METHODS: Sixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups. RESULTS: The total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01). CONCLUSION: Jin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

[Treatment of autism children: observation on efficacy of behavior training with retention of needles on head].

OBJECTIVE: To observe the effect difference of behavior training with head needling retention and behavior training after acupuncture for autism children. METHODS: Sixty qualified autism children were divided randomly into simultaneous head needling retention and behavior training group (trial group) and behavior training after acupuncture treatment group (control group) with 30 case in each group. Retention needles on the head with simultaneous behavior training was applied for the trial group. The main acupoints included Sishen Xue, Dingshen Sanxue (3 points for mental tranquilization), Nao Sanxue (3 points for the function of brain), Shou Zhisanxue (3 points for mental activities on hand) and Zozhi Sonxue (3 points for mental activities on foot). Other points were combined according to conditions of patients. Needles on the 4 extremities were withdrawn first after 30 minutes, needles on head were remained during behavior training. While behavior training was applied to the control group when acupuncture treatment was completely accomplished. Treatments were applied once a day to both groups. And 3 months was taken as one observation cycle. Estimation was made on therapeutic effect and developing level of autism children with CARS and PEP. RESULTS: The total effective rate of the trial group was 83.3% (25/30), better than 66.7% (20/30) of the control group (P < 0.05). The CARS scores of both groups declined after the treatment. And the score of trail group was lower than the control group (all P < 0.05). While the PEP scores of both groups increased, and the score of trail group was higher than the control group (all P < 0.05). The increasing level of scores of cognitive understanding and cognitive expression were all better than the control group (all P < 0.05). CONCLUSION: The effect of behavior training with head needle retention on autism children is better than behavior training after acupuncture treatment, especially in enhancing cognition understanding and cognition expression.
