Abstract
BACKGROUND The aim of the study was to investigate whether the expression of CD27-CD38+ in interferon (IFN)-γ+CD4+ T cells stimulated by the specific antigen early secreted antigenic target-6 (ESAT-6)/culture filter protein-10 (CFP-10) could be a potential new therapeutic evaluation indicator for anti-tuberculosis (TB) treatment. METHODS Newly diagnosed active pulmonary TB patients, latent TB infection (LTBI) and healthy controls were enrolled from January 2021 to December 2021. PTB patients were treated by standard anti-TB regimen 2HREZ/4HR (2 months of isoniazid (H), rifampin (R), ethambutol (E), and pyrazinamide (Z) followed by 4 months of isoniazid (H) and rifampin (R)). The difference of CD27-CD38+ expression in IFN-γ+CD4+ T cells before treatment, 2 months after treatment, and 6 months after treatment were compared. RESULTS Total 45 PTB patients, 38 LTBI cases and 43 healthy controls were enrolled. The expression of CD27-CD38+ decreased significantly after anti-TB treatment and was comparable with that in LTBI and healthy controls when the 6-month anti-TB treatment course was completed. The decline rate of CD27-CD38+ between 6 months after treatment and baseline was positively correlated with erythrocyte sedimentation rate (r = 0.766, P < 0.0001), C-reactive protein (r = 0.560, P = 0.003) and chest computerized tomography severity score (r = 0.632, P = 0.0005). The area under receiver operator characteristic curve of CD27-CD38+ in distinguish pulmonary TB patients before and after treatment was 0.779. CONCLUSION The expression of CD27-CD38+ in ESAT-6/CFP-10 stimulated IFN-γ+CD4+T cells can well reflect the changes of the disease before and after anti-TB treatment, which is expected to be a potential new therapeutic evaluation index. Clinical Registry number chiCTR1800019966.

Abstract
Waste printed circuit boards (WPCBs) are an attractive secondary resource that is challenging to dispose of due to its complexity. Reverse flotation is an effective method to remove non-metallic particles (NMPs) to obtain metals from WPCBs. Nevertheless, the removal of NMPs is usually inadequate in the present flotation practice. Thus, to provide a clean approach to improve the removal efficiency of NMPs, the method of adding gutter oil during dry grinding process was adopted to enhance the hydrophobic sites on the surface of NMPs to improve the floatability. The surface morphology of NMPs was analyzed by SEM, the results show that the rough morphology inhibited the adhesion of bubbles, while water occupied the cracks and pores, making it challenging for collector adsorption, which result in unstable particle-bubble adhesion. The results of FTIR indicate that both NMPs and gutter oil have -CH3, -CH2, -C = O, -C-O functional groups, which promotes the adsorption of gutter oil on the surface of NMPs. The contact angle (CA) results show that the adsorption of gutter oil on the particle surface is conducive to the formation of enhanced CA. Furthermore, the flotation enhancement effect was verified by flotation kinetic experiments. The accumulated floats yield of NMPs conditioned by gutter oil during grinding is increased from 67.05% (NMPs without conditioning) to 95.02%, and the resin recovery is increased by 31.10%. It is demonstrated that dry grinding with gutter oil can strengthen the floatability of NMPs, which provides a potential approach to increase the flotation efficiency of WPCBs.

Abstract
OBJECTIVE To investigate the neuroprotective effect of electroacupuncture (EA) at "Quchi" (LI 11) and "Zusanli" (ST 36) in the rats with cerebral ischemic reperfusion and the potential mechanism of microglia pyroptosis. METHODS Sixty SD rats were randomly divided into a sham-operation group, a model group and an EA group, with 20 rats in each group. The Zea Longa method was employed to establish the rat model of the middle cerebral artery occlusion and reperfusion (MACO/R) in the left brain. In the EA group, since the 2nd day of modeling, EA was given at "Quchi" (LI 11) and "Zusanli" (ST 36) of right side with disperse-dense wave, 4 Hz/20 Hz in frequency and 0.2 mA in current intensity, 30 min each time, once a day for lasting 7 consecutive days. The reduction rate of cerebral blood flow was measured with laser Doppler flowmetry during operation. The neurological function of rats was observed using Zea Longa neurobehavioral score. The cerebral infarction volume was detected by TTC staining method. The microglia positive expression in the ischemic side of the cortex was detected with the immunofluorescence method. Under transmission electron microscope, the ultrastructure of cell in the ischemic cortex was observed. The mRNA expression levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), cysteinyl aspartate specific proteinase-1 (Caspase-1) and gasdermin D (GSDMD) in the ischemic cortex were detected using real-time PCR. RESULTS Compared with the sham-operation group, in the model group, the reduction rate of cerebral blood flow was increased during operation (P<0.001); Zea Longa neurobehavional score and the percentage of cerebral infarction volume were increased (P<0.001), the numbers of M1-type microglia marked by CD68+ and M2-type microglia marked by TMEM119+ were elevated in the ischemic cortex (P<0.001), the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was increased (P<0.001, P<0.01); the cytomembrane structure was destroyed, with more cell membrane pores formed in the ischemic cortex. Compared with the model group, after intervention, Zea Longa neurobehavioral score and the percentage of cerebral infarction volume were reduced (P<0.05), the number of M1-type microglia marked by CD68+ was reduced (P<0.05) and the number of M2-type microglia marked by TMEM119+ was increased (P<0.05); and the mRNA expression of NLRP3, ASC, Caspase-1 and GSDMD was decreased (P<0.01, P<0.05) in the EA group. Even though the cytomembrane structure was incomplete, there were less membrane pores presented in the ischemic cortex in the EA group after intervention. CONCLUSION The intervention with EA attenuates the neurological dysfunction and reduces the volume of cerebral infarction in the rats with cerebral ischemic reperfusion. The underlying mechanism is related to the inhibition of microglia pyroptosis through modulating NLRP3/Caspase-1/GSDMD axis.

Abstract
BACKGROUND This retrospective study aimed to evaluate the diagnostic value of early secretory antigenic target-6 (ESAT-6) and culture filtrate protein-10 (CFP-10) in immunoglobulin A nephropathy (IgAN) associated with renal tuberculosis (RT). METHODS Forty patients with IgAN (IgAN group), 32 patients with RT (RT group), and 52 patients with IgAN associated with RT (IgAN + RT group) were retrospectively selected for this study. A tuberculin skin test (TST) was conducted, and Mycobacterium tuberculosis (MTB) antibody levels were measured. Immunohistochemistry and western blotting were used to determine the expression of ESAT-6 and CFP-10 proteins in renal tissues. RESULTS The positive results of TST and levels of serum and urinary MTB antibodies were higher in the RT group than in the IgAN + RT group. The expression levels of ESAT-6 and CFP-10 proteins were the highest in the IgAN + RT group and lowest in the IgAN group. The receiver operating characteristic curves indicated that the area under curve (AUC) value of the ESAT-6 protein for the diagnosis of IgAN associated with RT was 0.907 and the cut-off value of the integral optical density (IOD) was 26.72. Diagnosis based on ESAT-6 protein levels showed 75% sensitivity and 94.2% specificity. The AUC value of the CFP-10 protein for the diagnosis of IgAN associated with RT was 0.8 and the cut-off value of IOD was 25.67. Detection based on CFP-10 protein levels showed 63.9% sensitivity and 84.6% specificity. CONCLUSIONS Our study provides evidence for the potential of ESAT-6 and CFP-10 proteins as candidate markers in the diagnosis of IgAN associated with RT.

Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) on modified neurological severity score (mNSS), cerebral infarction volume, expression of Lim domain kinase-1 (LIMK1) and slingshot homolog-1 (SSH1) proteins, Cofilin rod formation and neural cell apoptosis in rats with ischemic stroke (IS), so as to explore its mechanisms underlying improvement of IS. METHODS Male SD rats were randomly divided into normal, model and EA groups, with 13 rats in each group. The IS model was established by occlusion of the middle cerebral artery (MCAO) according to Zea Longa's method. EA was applied to "Quchi" (LI11) and "Zusanli" (ST36) for 30 min, once a day for 7 consecutive days. The behavioral changes of mNSS were observed before and after modeling. The volume of cerebral infarction was measured by using a small animal magnetic resonance imaging. The protein expressions of LIMK1 and SSH1 in the cerebral ischemic tissues were detected by Western blot. The density of Cofilin rod and neural cell apoptosis in cerebral ischemic area were determined by immunofluorescence staining and TUNEL staining, separately. RESULTS After modeling, the mNSS score, cerebral infarction volume ratio, expression level of SSH1, density of Cofilin rod and the number of apoptotic cells were significantly increased (P<0.01), while the expression level of LIMK1 protein was obviously decreased in the model group relevant to the normal group (P<0.01). After 7 days' treatment, all the increased and decreased levels of the indexes mentioned above were reversed in the EA group relevant to the model group (P<0.01, P<0.05). CONCLUSION EA of LI11 and ST36 can improve neurological function and reduce infarction range in MCAO rats, which may be related to its action in regulating the expression of LIMK1 and SSH1, inhibiting the formation of Cofilin rod and reducing apoptosis of neural cells.

Abstract
IG-105, N-(2, 6-dimethoxypyridine-3-yl)-9-methylcarbazole-3-sulfonamide, a novel carbazole sulfonamide, shows a potent anticancer activity in a variety of human tumor cells in vitro and in vivo. In the present study, a rapid and convenient liquid chromatography/tandem mass spectrometry (LC-MS/MS) method was developed and applied to the pharmacokinetic study of IG-105 in rats. Chromatographic separation was accomplished on a C18 column using an isocratic mobile phase of acetonitrile-water-acetic acid (56:44:0.2, v/v/v). The ion transitions of IG-105 and combretastatin A4 (internal standard) in selected reaction monitoring mode were m/z 398→154 and m/z 317→286, respectively. The assay exhibited good linearity over the range of 2-512 ng/mL. Intra- and inter-day precisions were within 8.2 %, and the accuracies ranged from -6.0 to 3.7 %. The extraction recoveries were higher than 90 %, and the matrix effects were negligible. All quality control samples were stable at different storage conditions. The validated LC-MS/MS method was successfully applied to a preclinical pharmacokinetic study of IG-105 in rats after a single oral dose of 100, 250, or 1000 mg/kg which showed tumor growth inhibition activity. The absorption of IG-105 was proved to be rapid but saturated to a certain extent into the blood circulation, from where it was distributed and eliminated gradually.

Abstract
Objective: To evaluate the clinical characteristics and the corresponding MRI and laboratory findings in patients with neuromyelitis optica spectrum disorder (NMOSD) associated with area postrema (AP). Methods: The study was a retrospective analysis of data from 120 NMOSD patients, and 18 cases were with AP out of these patients, The clinical presentation, MRI changes, serological markers and treatment outcome were reported. Results: AP occurred in 18 patients (15%, 18/120). AP was the onset symptom in 14 (14/18) patients and 3 days to 7 months (median 40 days) later, optic neuritis or myelitis was involved. One patient presented AP after optic neuritis. Three patients (3/18) had AP and myelitis or optic neuritis simultaneously. AP symptom presented as intractable nausea and vomiting, hiccups. Compared to the patients without AP (n=102), the patients with AP (n=18) had shorter duration and fewer numbers of optic neuritis(P<0.05). There was no statistical difference in sex, onset age, course of disease (relapsing or monophasic) and EDSS scores (P>0.05). The MRI revealed flake or linear lesions in medulla. Twelve patients had cervical cord lesions extending to medulla lesions (12/18). Eleven patients had long cord lesions extending more than 3 spinal cords. The AQP4-antibody did not differ in patients with or without AP (14/18 vs 75/102). The symptom of AP was successfully relieved with methylprednisolone. Conclusion: AP symptoms/signs are common in patients with NMOSD. Vomiting and hiccups can be the first symptoms. The medulla lesions and the lesions extending to upper cervical cord are unique to NMOSD. Awareness of AP presentations is helpful for early diagnosis and proper treatment to prevent further disability.

Abstract
OBJECTIVE To study the MRI features of ventricular system tuberculosis. METHODS Nineteen patients with ventricular system tuberculosis in our hospital from Mar. 2009 to Sep. 2014 were retrospectively identified. Their clinical features and cranial MRI characteristics were reviewed. RESULTS There were 13 males and 6 females, aged from 15-81 years(mean 37±16). Eight patients had intraventricular tuberculosis, with 5 long striped or irregular shaped intraventricular tuberculosis and 3 with ventricular tuberculoma. Six patients had tubercular ependymitis and 5 had intraventricular tuberculosis along with tubercular ependymitis. The lesions of 14 patients were in the lateral ventricle; 13 in occipital or temporal horn of lateral ventricle, 9 complicated by tubercular meningitis, and 10 complicated by brain tuberculoma. The lesion of 5 patients were in the fourth ventricle, 5 in the postmedian of the fourth ventricle, 5 complicated by tubercular meningitis and 4 complicated by hydrocephalus. There were 4 cases with ring-enhancement and 15 with heterogeneous enhancement. Ten cases were complicated by peripheral edema. CONCLUSIONS The diagnosis of ventricle system tuberculosis is difficult due to its low incidence. The site, cranial MRI characteristics, the patterns of enhancement and complications have certain specificity and are useful in the diagnosis of ventricular system tuberculosis.

Abstract
Numerous epidemiological and experimental animal studies have indicated that chronic psychological stress may promote tumor development. However, the underlying molecular mechanisms by which chronic stress promotes tumorigenesis remain to be fully elucidated and animal models have not yet been well established. In the present study, an established mouse model of repeated social defeat stress (RSDS), was generated and used to investigate the effect of stress on tumor growth and metastasis. C57BL/6 mice were exposed to RSDS for 10 days, followed by subcutaneousl inoculation with Lewis lung carcinoma cells for seven days. The tumor weight and volume as well as the number of the lung metastatic nodules were then determined. Vascular endothelial growth factor (VEGF) serum levels were measured using ELISAs. In addition, expression levels of VEGF receptor (VEGFR) and L1 cell adhesion molecule (L1CAM) messenger (m)RNA were confirmed using reverse transcription quantitative polymerase chain reaction. Furthermore, protein expression levels of phosphorlyated extracellular signal-regulated kinase (pERK), matrix metalloproteinase (MMP)-2 and MMP-9 were examined using western blot analysis. The results showed that RSDS significantly increased the weight and the volume of the primary tumor as well as the number of the lung metastatic nodules. Serum VEGF levels were significantly higher in the tumor-stress group compared with those of the unstressed tumor mice. In addition, tumors in stressed animals demonstrated markedly enhanced expression of VEGFR-2 and L1CAM mRNA as well as pERK, MMP-2 and MMP-9 protein expression. In conclusion, these results suggested that RSDS contributed to lung cancer progression, angiogenesis and metastasis, which was partially associated with increased VEGF secretion and therefore the activation of the ERK signaling pathway, resulting in the induction of MMP-2 and MMP-9 protein expression.

Abstract
Carcinogenic and mutagenic polycyclic aromatic hydrocarbons (PAHs) generated in coal combustion have caused great environmental health concern. Seventeen PAHs (16 high priority PAHs recommended by USEPA plus Benzo[e]pyrene) present in five raw bituminous coals and released during bituminous coal combustion were studied. The effects of combustion temperature, gas atmosphere, and chlorine content of raw coal on PAHs formation were investigated. Two additives (copper and cupric oxide) were added when the coal was burned. The results indicated that significant quantities of PAHs were produced from incomplete combustion of coal pyrolysis products at high temperature, and that temperature is an important causative factor of PAHs formation. PAHs concentrations decrease with the increase of chlorine content in oxygen or in nitrogen atmosphere. Copper and cupric oxide additives can promote PAHs formation (especially the multi-ring PAHs) during coal combustion.
