ABSTRACT

BACKGROUND: Insulin autoimmune syndrome (IAS) is a severe manifestation of spontaneous hypoglycemia. It is characterized by elevated levels of immune-reactive insulin and highly potent insulin autoantibodies (IAAs), which are induced by endogenous insulin circulating in the bloodstream. It is distinguished by recurring instances of spontaneous hypoglycemia, the presence of IAA within the body, a substantial elevation in serum insulin levels, and an absence of prior exogenous insulin administration. Nevertheless, recent studies show that both conventional insulin and its analogs can induce IAS episodes, giving rise to the notion of non-classical IAS. Therefore, more attention should be paid to these diseases. CASE SUMMARY: In this case report, we present a rare case of non-classical IAS in an 83-year-old male patient who present with symptoms of a psychiatric disorder. Upon symptom onset, the patient exhibited Whipple's triad (including hypoglycemia, blood glucose level less than 2.8 mmol/L during onset, and rapid relief of hypoglycemic symptoms after glucose administration). Concurrently, his serum insulin level was significantly elevated, which contradicted his C-peptide levels. After a comprehensive examination, the patient was diagnosed with exogenous insulin autoimmune syndrome. Considering that the patient had type 2 diabetes mellitus and a history of exogenous insulin use before disease onset, it was presumed that non classical IAS was induced by this condition. The PubMed database was used to search for previous cases of IAS and non-classical IAS to analyze their characteristics and treatment approaches. CONCLUSION: The occurrence of non-classical IAS is associated with exogenous insulin or its analogs, as well as with sulfhydryl drugs. Symptoms can be effectively alleviated through the discontinuation of relevant medications, administration of hormones or immunosuppressants, plasma exchange, and lifestyle adjustments.

ABSTRACT

AIMS: The commonly used treatments of adult degeneration scoliosis (ADS) were posterior long segment screw fixation with osteotomies. Recently, lateral lumbar intervertebral fusion combined two-stage posterior screw fixation (LLIF + PSF) as a new strategy without osteotomy. Herein, this study aimed to compare the clinical and radiological outcomes among LLIF + PSF and pedicle subtraction osteotomy (PSO), posterior column osteotomies (PCO). METHODS: Totals of 139 ADS patients underwent operation with 2 years longer follow-up visit between January 2013 and January 2018 in Ningbo No.6 Hospital were enrolled into this study. 58 patients were included in PSO group, 45 in PCO group and 36 in LLIF + PSF group, The clinical and radiological data were reviewed from medical records. Baseline characteristic, perioperative radiological data (sagittal vertical axis (SVA), coronal balance (CB), Cobb angle of Mian curve (MC), Lumbar lordosis (LL), pelvic tilt (PT) and pelvic incidence-lumbar lordosis mismatch (PI-LL)), clinical outcomes (VAS of back and leg, Oswestry disability index (ODI) and Scoliosis Research Society 22-question Questionnaire (SRS-22)) and complications were evaluated and compared. RESULT: There were no significantly difference in baseline characteristics, preoperative radiological parameters and clinical outcomes among three groups. LLIF + PSF group was significantly shorter in operation time than other two groups (P < 0.05), whereas significant longer hospital stay was observed in LLIF + PSF group (P < 0.05). As for radiological parameters, LLIF + PSF group had significantly improvement in SVA, CB, MC, LL and PI-LL (P < 0.05). Moreover, LLIF + PSF group achieved significantly less correction loss in SVA, CB and PT than PSO and PCO group (1.5 ± 0.7 VS 2.0 ± 0.9 VS 2.2 ± 0.8, P < 0.05; 1.0 ± 0.4 VS 1.3 ± 0.5 VS 1.1 ± 0.7, P < 0.05 and 4.2 ± 2.8 VS 7.2 ± 3.1 VS 6.0 ± 2.8, P < 0.05). Significantly recovery in VAS of back and leg, ODI score and SRS-22 were found among all groups, however, LLIF + PSF shown significant better clinical therapy maintain at follow-up visit than other two groups (P < 0.05). There were no significantly difference in complications among groups (P = 0.66). CONCLUSION: Lateral lumbar interbody fusion combined two-stage posterior screw fixation (LLIF + PSF) can achieve comparable clinical therapy for adult degeneration scoliosis as osteotomy strategies. However, furthermore more studies need be taken for verifying the effect of LLIF + PSF in the future.

ABSTRACT

Objective: We attempted to clarify the effect of lncRNA MSC-AS1 on carcinogenic and development of nasopharyngeal carcinoma (NPC) and the related mechanisms. Methods: The levels of MSC-AS1 and miR-429 were estimated in NPC tissues and cells using qRT-PCR. Correlation analysis, dual-luciferase report, and RNA pull down assay assessed the action association of MSC-AS1 and miR-429. MTT, colony formation, cell wound scratch, and transwell assays were used to assess the proliferation, invasion, and migration of C666-1 cells. Metastasis-related protein expressions and activation of the JAK1/STAT3 pathway were confirmed by western blot and immunohistochemistry. Results: The expression of MSC-AS1 presented significant upregulation, and miR-429 expression was markedly downregulated in NPC tissues and cells. The level of MSC-AS1 had negative relation to the miR-429 level. Knockdown of MSC-AS1 suppressed the proliferation, invasion, and migration of C666-1 cells. On the contrary, overexpressing of MSC-AS1 exerts the opposite effects on C666-1 cell growth and migration. miR-429 was determined as functional downstream of MSC-AS1. The suppressive function of MSC-AS1 knockdown was predominately abolished by the miR-429 inhibitor. miR-429 was an antitumor gene inhibiting NPC growth and metastasis through JAK1/STAT3 pathway. In C666-1 cells, the elevated cell growth and migration induced by the miR-429 inhibitor were significantly reversed by si-JAK1 transfection. Conclusions: High expression of MSC-AS1 exerted a carcinogenic effect on NPC cell growth and metastasis by inhibiting miR-429 and activating the JAK1/STAT3 pathway.

ABSTRACT

OBJECTIVE: To observe the effect of horizontal penetration needling at vertigo auditory area and balance area on residual dizziness after successful repositioning maneuver in patients with benign paroxysmal positional vertigo (BPPV). METHODS: Sixty-six patients with residual dizziness after successful repositioning maneuver for BPPV were randomly divided into an observation group (34 cases, 1 case dropped off) and a control group (32 cases, 2 cases dropped off). The patients in the observation group were treated with horizontal penetration needling at vertigo auditory area and balance area, once every other day; three times were taken as a course of treatment, and two courses of treatment were given. The patients in the control group received no acupuncture and medication. The dizziness handicap inventory (DHI) and visual analogue scale (VAS) scores were observed before treatment and after 1 and 2 courses of treatment. RESULTS: Except for the emotional score of DHI in the control group after 1 course of treatment, the sub item scores and total scores of DHI and VAS scores in the two groups after treatment were lower than those before treatment (P<0.01, P<0.05). After 1 and 2 courses of treatment, the function scores, emotion scores, total scores of DHI and VAS scores in the observation group were lower than those in the control group (P<0.01). CONCLUSION: Whether acupuncture or not, residual dizziness after repositioning maneuver for BPPV can be relieved within 2 weeks; horizontal penetration needling at vertigo auditory area and balance area could improve dizziness symptoms and shorten the course of disease.

ABSTRACT

AIMS: The preclinical evaluation of innovative drugs plays an important role in the new drugs development. As a derivative of pirfenidone (PFD), mefunidone (MFD) has shown better anti-fibrosis and anti-inflammatory activity in both cell lines and animal models. To support the clinical investigations of MFD, the metabolic characterization of MFD was initially evaluated in preclinical models. MAIN METHODS: The potential metabolites of MFD were analyzed by LC-MS/MS methods. The induction effect of MFD on CYP1A2, CYP2B6, and CYP3A4 was performed in primary human hepatocytes, and the inhibition of CYP enzymes by MFD was also evaluated in human liver microsomes. Finally, the pharmacokinetic profiles of MFD were assessed in SD rats after the rats had received multiple doses (62.5 mg/kg) of MFD. KEY FINDINGS: MFD was metabolized in three pathways including oxidation, N-demethylation, and hydroxylation. Except for slight inhibition on the activity of CYP2D6, MFD exerted no effect on other CYP enzymes. Moreover, drug accumulation of MFD was not observed in rats after repeated dosing of MFD. SIGNIFICANCE: MFD was first discovered in preclinical investigations without inducing and inhibiting metabolic enzymes. This work provides some important information about the metabolic characterization of MFD for its further clinical investigations.

ABSTRACT

Cancer is a common disease threatening human health, chemotherapy is widely used in clinical treatment of cancer, but chemotherapy-induced peripheral neuropathy (CIPN) has a relevant impact on life quality of cancer patients. Administration of gastrodin can relieve chronic pain to cancer patients with CIPN and attenuated the inflammatory response by reducing the expression of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). However, its exact molecular mechanisms remain unclear. In this study, we established an animal model of CIPN using Walker-256 breast cancer cell and vincristine. We found that the mechanical and thermal pain threshold of rats was decreased with treatment of vincristine. Using gastrodin could restore the mechanical and thermal threshold without interfering anti-tumor effect of vincristine. Gastrodin relieved CIPN by inhibiting activation of spinal microglia through Fractalkine (CX3CL1) and its receptor CX3CR1, then inhibited P38/mitogen-activated protein kinase (MAPK) signaling pathway and reduced the expression of inflammatory factor TNF-α and interleukin-1ß (IL-1ß). Taking together, our study demonstrated that gastrodin is a potential drug for the treatment of CIPN and likely to improve cancer patient's life quality.

ABSTRACT

Fabricating nanostructures and doping engineering are beneficial to tailor the photocatalytic activity of semiconductor materials, and the semiconducting photocatalysis is deemed to be one of the potential protocols to handle the environmental pollution and energy crisis issues. Herein, rodlike Cd-doped ZnWO4 Zn1-x Cd x WO4 nanoarchitectures were triumphantly prepared by a template-free strategy. The crystal structure, chemical state, optical, and photocatalytic features of the Zn1-x Cd x WO4 nanoarchitectures were studied using a variety of characterizations. The Zn1-x Cd x WO4 nanoarchitectures exhibit glorious photocatalytic performance compared with pristine ZnWO4 for the degradation of methyl orange in sewage. Mechanistic studies were executed for getting insights into the photocatalytic degradation process, and the remarkable photocatalytic property of the doped ZnWO4 nanoarchitectures is attributed to the boosted optical absorptive efficiency and the valid segregation and transmission of photogenerated charge carriers deriving from doping effects. The doped nanoarchitectures of this work have promising applications in the territories such as environment and energy chemistry, and the insight proposed in this work will contribute to develop other functionalized nanoarchitectures.

ABSTRACT

By analyzing Fu 's subcutaneous needling phenomenon, the attribute of Fu 's subcutaneous needling therapy in traditional acupuncture, the innovation and the role in the development of traditional acupuncture were demonstrated. The authors believe that the de-meridian in Fu 's subcutaneous needling therapy is similar to the connotation of meridian before the Han dynasty, the de-acupoint phenomenon in Fu 's subcutaneous needling therapy reproduces the acupoint evolution, and the sites of needle insertion of this therapy are partially overlapped with the location of traditional acupoints. In manipulation, the technique of Fu 's subcutaneous needling therapy is derived from the traditional acupuncture technique and it is also in reference to the theory and the method of modern medicine, such as muscle energy technology and fasciology. The needle device and the sweeping technique are the most essential innovation of Fu 's subcutaneous needling therapy. Fu 's subcutaneous needling therapy has the distinct attribute of traditional acupuncture.

ABSTRACT

The problems of the syndrome differentiation of migraine in acupuncture treatment were collected, e.g. inconsistency of syndrome differentiation, unclear staging of syndrome differentiation, lack of standardization in comparison between syndrome differentiation and non-differentiation, insufficient research on the factors of syndrome differentiation. In view of the exiting problems, focusing on two aspects of migraine, namely syndrome differentiation and acupuncture effect, the clinical treatment and research are conducted in migraine treated with acupuncture based on syndrome differentiation. It is believed that the comprehensive observation of the relationship between syndrome differentiation and acupuncture effect, as well as the analysis of the relevant factors of syndrome differentiation of migraine should be the focus in future research.

ABSTRACT

The manipulation and key points of professor FAN Gang-qi 's horizontal penetration needling method for headache were introduced. This acupuncture method selects local acupoints of head, including occipital acupoint group, temporal acupoint group, frontal acupoint group and vertex acupoint group. The needles are shallowly and horizontally inserted at acupoints, with needle end towards the focus or headache site. The needle retaining time is long (6 h). This method is commonly used in the treatment of migraine, cervicogenic headache and tension-type headache. The manipulation is standard with better repeatability.

ABSTRACT

PURPOSE: Extracorporeal shock wave therapy (ESWT) has been reported as a new therapy for carpal tunnel syndrome (CTS). However, few studies have compared ESWT with the local corticosteroid injection (LCI). METHODS: In this study, a randomized controlled trial comparing 30 patients with ESWT and 25 patients treated with LCI was conducted. The clinical outcomes were obtained with tests including the visual analog scale (VAS) for pain and paresthesia, the Boston Carpal Tunnel Questionnaire (BQ), and a nerve conduction study, before the study started and at three, nine, and 12 weeks after the start of the treatment. RESULTS: Significantly greater improvement in the VAS and BQ scores was noted for the ESWT group than for the LCI group (P < 0.05). For the nerve conduction study, there was a significant improvement in the median nerve sensory nerve action potential distal latency at the nine and 12-week follow-ups for the ESWT group. CONCLUSIONS: ESWT is a useful noninvasive short-term treatment for mild to moderate carpal tunnel syndrome and elicits a better recovery than LCI does, but more research is needed to test the clinical outcomes of ESWT.

ABSTRACT

Banana trees, citrus fruit trees, pome fruit trees, grapevines, mango trees, and stone fruit trees are major fruit trees cultured worldwide and correspond to nearly 90% of the global production of woody fruit trees. In light of the above, the present manuscript summarizes the viruses that infect the major fruit trees, including their taxonomy and morphology, and highlights selected viruses that significantly affect fruit production, including their genomic and biological features. The results showed that a total of 163 viruses, belonging to 45 genera classified into 23 families have been reported to infect the major woody fruit trees. It is clear that there is higher accumulation of viruses in grapevine (80/163) compared to the other fruit trees (each corresponding to less than 35/163), while only one virus species has been reported infecting mango. Most of the viruses (over 70%) infecting woody fruit trees are positive-sense single-stranded RNA (+ssRNA), and the remainder belong to the -ssRNA, ssRNA-RT, dsRNA, ssDNA and dsDNA-RT groups (each corresponding to less than 8%). Most of the viruses are icosahedral or isometric (79/163), and their diameter ranges from 16 to 80 nm with the majority being 25-30 nm. Cross-infection has occurred in a high frequency among pome and stone fruit trees, whereas no or little cross-infection has occurred among banana, citrus and grapevine. The viruses infecting woody fruit trees are mostly transmitted by vegetative propagation, grafting, and root grafting in orchards and are usually vectored by mealybug, soft scale, aphids, mites or thrips. These viruses cause adverse effects in their fruit tree hosts, inducing a wide range of symptoms and significant damage, such as reduced yield, quality, vigor and longevity.

ABSTRACT

The continuing emergence of drug-resistant Helicobacter pylori (HP) drives the ongoing need for the development of new and effective anti-HP drugs. Urease inhibitor has now gained strong interest as an alternative approach for HP infections. 3-Chlorophenyl-3-hydroxypropionylhydroxamic acid (CPH), a novel urease inhibitor identified in our group, shows impressive potency, which was optically separated for a further exploration. Here, we report in vitro/in vivo pharmacological evaluation of (±)-CPHs and the enantiomers. The raceme and the individual enantiomers significantly suppress gastritis at 32 mg/kg b.i.d dose with lower toxicity to mammalian cells (with CC50s ≥ 3.16 mM) and mice (LD50s ≥ 2338 mg/kg) than the clinically used agent acetohydroxamic acid. Furthermore, a significant increase of eradication of HP is observed for the combination of (±)-CPHs or the enantiomers with an antimicrobial. These studies revealed that CPH is a promising candidate for an alternative treatment of HP-dependent conditions by targeting virulence factor urease, and CPH may be used as a raceme.

ABSTRACT

Electroacupuncture (EA) has been extensively used in clinical treatment of obesity. The effectiveness relies not only on the correct diagnosis and rational treatment, but also on the voluntary cooperation of patients, that is the satisfactory compliance. The patient compliance refers to his/her submissiveness and executive ability to medical advice, which is the indispensable factor for the clinical efficacy. The strength of it depends on the patient himself/herself, and moreover is improved through some therapeutic strategies. Based on the emphasis of individual treatment in the real world, the practical randomized controlled trial (RCT) study pays attention to patient's compliance at the beginning of trial design. In this paper, in terms of the influential factors and control strategies, the compliance of simple obesity patient in the practical RCT study was summarized systematically.

ABSTRACT

This study aims to develop a method for determination of beta-elemene, curcumol, germacrone and neocurdione in the volatile oil of Curcuma phaeocaulis, and to provide the basis of the quality control method for the volatile oil of C. phaeocaulis and the related preparations. Based on GC-MS, the 4 main compounds were simultaneously determined, with the internal standard n-tridecane. The Agilent 19091S-433 column (0.25 microm x 250 microm x 30 m) was adopted at the temperature of 250 degrees C, the programmed temperature method (60 degrees C for 1 min, 5 degrees C x min x to 110 degrees C for 5 min, 1 degrees C x min(-1) to 140 degrees C, 5 degrees C x min(-1) to 160 degrees C, 10 degrees C x min(-1) to 240 degrees C) was used. Helium gas was used as the carrier gas at a constant flow rat of 1 mL x min(-1), with an injection volume of 1 RL. Mass spectra were taken at 70 eV; the ion-source temperature was 200 degrees C. The relation time and character acteristic ions for each target compound were determined by full scan mode and SIM, and m/z 85.1, 93.1, 121.1, 107.1 and 180.1 were the detection ions of n-tridecane, beta-elemene, curcumol, germacrone and neocurdione. As a result, beta-elemene, curcumol, germacrone and neocurdione were all detected with good separation. They were all in a good linear relationship within each concentration scope. The average recovery rates were in the range of 98.2%-101%. So, the method can be used to control the quality of the volatile of C. phaeocaulis Val. and the preparations related.

ABSTRACT

OBJECTIVE: To explore the epidemiological status and risk factors of hyperuricemia in rural area of the Three Gorges. METHODS: A cross-sectional survey was carried out in rural area of Yiling District, Yichang City, which was located north-west bank of Xiling Gorge in 2007. A standard structure questionnaire was used to collect demographic data, social-economic status and life-style features. Fasting venous blood was collected and serum uric acid (SUA) was determined. Hyperuricemia was defined as SUA levels ≥ 417 µ mol/L (70 mg/L) in men and ≥ 357 µmol/L (60 mg/L) in women. Multiple logistic regression analysis was used to analysed the risk factors of hyperuricemia. RESULTS: A total of 9354 participants aged 35 and above were included, 19.9% (1866/9354) participants were the Three Gorges migrants. Serum uric acid level in men was significantly higher than that in women [(285.1 ± 80.2) µmol/L vs. (210.3 ± 65.0) µmol/L,P < 0.01].Serum uric acid level increased significantly in both genders in proportion to increase of age, and was higher in men than in women in all age groups (all P < 0.01). The age-adjusted prevalence was significantly higher in men than in women (5.6% vs. 3.3%, P < 0.01), and was also higher in men aged 35-44 and aged 45-54 than in women (both P < 0.01). There was no significance in prevalence of hyperuricemia in both men and women aged 55-64 and aged ≥ 65. After adjusting age, gender, educational level, migration and occupation, the multiple logistic regression analysis showed that the prevalence of hyperuricemia was higher in alcohol drinking participants than that of non-alcohol drinking participants (OR = 2.06, 95%CI:1.59-2.67, P < 0.01), and in participants used to consume less green vegetables and fruits than in participants consuming more green vegetables and fruits (OR = 1.77, 95% CI:1.27-2.47, P < 0.01). CONCLUSIONS: The prevalence of hyperuricemia is relatively low in rural area of the Three Gorges.Alcohol drinking and low intake of green vegetables and fruits are the risk factors of hyperuricemia in this population.
