Abstract
BACKGROUND We investigate the pain relief and safety of microwave ablation (MWA) combined with percutaneous vertebroplasty (PVP) in the treatment of metastatic vertebral tumors. METHODS This prospective pilot study enrolled patients with metastatic vertebral tumors treated between January 2018 and October 2019. The participants were randomized to the PVP and MWA + PVP groups. Clinical parameters, pain visual analog scale (VAS), analgesic use scores (AUS), and quality-of-life score (QLS) were compared between groups. RESULTS Sixty-seven participants were enrolled (PVP: n = 35; MWA + PVP: n = 32). There were no differences in bone cement injection volume, extravasation, and X-ray exposure time between the two groups (p > 0.05), but treatment costs were higher for the MWA + PVP group (26,418 ± 194 vs. 15,606 ± 148 yuan; p < 0.05). There were no significant improvements in VAS from baseline to 24 hours, 72 hours, 7 days, 1 month, and 3 months in the two groups (p > 0.05); at 6 and 12 months after the operation, the improvement from baseline was significant in the two groups (p < 0.05). The VAS was lower at 6 months (2.7 ± 0.7 vs. 3.2 ± 0.7) and 12 months (3.5 ± 0.8 vs. 4.0 ± 0.7) in the MWA + PVP group (both p < 0.01 vs. PVP). The AUS and QLS were improved with PVP at 6 and 12 months (p < 0.05) and with MWA + PVP at 12 months (p < 0.05). The AUS was lower at 6 and 12 months in the MWA + PVP group (p < 0.05 vs. PVP). CONCLUSION MWA combined with PVP might be a safe and effective palliative treatment for pain from metastatic vertebral tumors.

Abstract
BACKGROUND Pacing is the most effective and dependable method for treating complete atrioventricular block (AVB). OBJECTIVE The purpose of this study is to investigate the use of His bundle pacing (HBP) in patients with atrioventricular block. METHODS Patients who underwent HBP or right ventricular pacing (RVP) were enrolled and divided into two groups: the HBP group and the RVP group, respectively. We compared baseline clinical data, fluoroscopy duration, operation duration, pacing electrode parameters during the operation or follow-up, baseline QRS duration, and pacing QRS duration. RESULTS HBP was attempted in 48 patients and was successful in 34 patients who were included in the HBP group. In addition, 30 RVP patients were included in the RVP group. Fluoroscopy duration and operation duration were significantly longer in the HBP group compared to the RVP group. Compared to the RVP group, the HBP group had a higher pacing threshold, a lower R wave amplitude, and a shorter pacing QRS duration. At 6 months of follow-up, the pacing threshold remained higher, the R wave amplitude was significantly lower, and the end-diastolic diameter of the left ventricle was smaller in the HBP group. CONCLUSION HBP was safe and effective for atrioventricular block despite the longer fluoroscopy and operation duration in the HBP group when compared to the RVP group.

Abstract
AIMS To examine the diversity of protozoa in the rumen contents of cow. METHODS AND RESULTS Protozoa that inhabit the rumen were detected by PCR using protozoan-specific primers. Libraries of protozoan rDNA sequences were constructed from rumen fluid, solid tissues and epithelium. Twenty-three clones isolated from rumen fluid fell into two genera identified as Entodinium (69.6% of clones) and Epidinium (31.4% of clones). Of the clones isolated from rumen fluid, a moderate number were unidentifiable (30.4%). CONCLUSIONS The predominant protozoan genus identified in the whole rumen belonged to the Entodinium group (81.1%). Protozoa were not detected in the rumen epithelium. SIGNIFICANCE AND IMPACT OF THE STUDY These findings suggest that rumen fluid and solid tissues contain different protozoan populations that may play specific roles in rumen function. Quantitative PCR techniques and a more specific set of phylogenetic probes that distinguish between protozoan species are needed to determine the significance of newly identified groups and to determine the distribution of identified protozoan clusters in rumen microbial communities.

Abstract
OBJECTIVE To define the cell populations contributing to inflammation-associated respiratory impairment in Pneumocystis carinii pneumonia (PCP). METHODS The host inflammation response was observed in CD4+ T cell-depleted mice and in CD4+ and CD8+ T cell-depleted mice infected with P. carinii via intratracheal inoculation. RESULTS Mice depleted of both CD4+ and CD8+ T cells developed infection with neither increased respiratory rate nor lung injury. In contrast, mice depleted of CD4+ T cells alone exhibited severe pulmonary inflammation, and increased respiratory rates. Respiratory compromise was associated with the presence of activated CD8+ cells and neutrophils in the BALF. CONCLUSION The host's inflammatory cell response to P. carinii directly impairs pulmonary function and contributes to the pathogenesis of PCP, CD8+ T cells appear to play a major role.

Abstract
The 5' upstream region of the cellulose synthase operon ( bcs operon) has been isolated by cloning from Escherichia coli. A gene encoding YhjQ is located 1.0 kb upstream of the bcs operon in E. coli. The function of YhjQ remains unknown. Insertional inactivation of the yhjQ gene causes abnormal cell division, resulting in incomplete partition of the chromosome and filamentous cells of various sizes. These results suggest that the product of yhjQ may affect normal doubling and cellular morphology.

Abstract
Aquifex aeolicus is the hyperthermophilic bacterium known, with growth-temperature maxima near 95 degrees C. The cel8Y gene, encoding a thermostable endoglucanase (Cel8Y) from Aquifex aeolicus VF5, was cloned into a vector for expression and expressed in Escherichia coli XL1-Blue. A clone of 1.7 kb fragment containing endoglucanase activity, designated pKYCY100, was sequenced and found to contain an ORF of 978 bp encoding a protein of 325 amino acid residues, with a calculated molecular mass of 38,831 Da. This endoglucanase was designated cel8Y gene. The endoglucanase has an 18-amino-acid signal peptide but not cellulose-binding domain. The endoglucanase of A. aeolicus VF5 had significant amino acid sequence similarities with endoglucanases from glycosyl hydrolase family 8. The predicted amino acid sequence of the Cel8Y protein was similar to that of CMCase of Cellulomonas uda, BcsC of Escherichia coli, CelY of Erwinia chrysanthemi, and CMCase of Acetobacter xylinum. The molecular mass of Cel8Y was calculated to be 36,750 Da, which is consistent with the value obtained from result of CMC-SDS-PAGE of the purified enzyme. Cel8Y was thermostable, exhibiting maximal activity at 80 degrees C and pH optima of 7.0 and with half-lives of 2 h at 100 degrees C, 4 h at 90 degrees C.

Abstract
The clinical severity of Pneumocystis carinii pneumonia (PCP) correlates closely with the appearance of pulmonary markers of inflammation. Therefore, a model system was developed whereby physiological studies could be performed on live mice to determine the extent to which pulmonary inflammation contributes to respiratory impairment during PCP. P. carinii-infected severe combined immunodeficient mice displayed little evidence of pulmonary inflammation and exhibited normal oxygenation and dynamic lung compliance. When comparably infected littermates were immunologically reconstituted, however, an intense immune-mediated inflammatory response was observed that resulted in significant decreases in both lung compliance and oxygenation. As the pneumonia resolved pulmonary function returned toward normal. To begin to define the cell populations contributing to inflammation-associated respiratory impairment during PCP, similar studies were performed in CD4(+) T cell-depleted mice. Mice depleted of both CD4(+) and CD8(+) cells developed infection, but they demonstrated neither abnormal lung compliance nor increased respiratory rate and displayed no markers of lung injury. In contrast, mice depleted of only CD4(+) T cells exhibited severe pulmonary inflammation and injury, decreased oxygenation and lung compliance, and increased respirations. Respiratory compromise was associated with the presence of activated CD8(+) cells and neutrophils in broncho-alveolar lavage fluid. These observations provide direct experimental evidence that the host's response to P. carinii directly impairs pulmonary function and contributes to the pathogenesis of PCP. Furthermore, CD8(+) T cells likely contribute to the respiratory compromise observed during PCP.
