Abstract
Objective: To explore the influencing factors of health-related quality of life (HRQoL) in patients with knee osteoarthritis, and to analyze the non-surgical treatment of knee osteoarthritis. Methods: Demographic variables, treatment modalities, imaging data, and 12-item short form health survey (SF-12) scores of patients with knee osteoarthritis in orthopedic outpatient departments of five hospitals in Beijing from December 2017 to November 2018 were collected to analyze influencing factors of HRQoL and non-surgical treatment. Results: A total of 2 034 patients were included. There were 530 males (26.1%) and 1 504 females (73.9%), with a mean age of (59.17±10.22) years. In terms of physical quality of life, female patients with knee osteoarthritis had lower physical components summary (PCS) compared with male patients (β=-0.521, P=0.036); patients aged ≥64 years had lower PCS than those aged<55 years (β=-0.636, P=0.026). Patients with an education of more than 12 years had higher PCS than those with less than 10 years (β=1.063, P<0.001). Compared to patients with mild clinical symptoms, the PCS of patients with moderate clinical symptoms was lower (β=-0.860, P=0.002), while the PCS of those with severe clinical symptoms was much lower (β=-1.126, P<0.001). Patients treated with combination therapy had higher PCS than untreated patients (β=0.731, P=0.005). In terms of mental quality of life, compared to patients engaged in sedentary work, the mental components summary (MCS) of patients engaged in mild manual labor jobs was lower (β=-0.712, P=0.015); Compared to patients with a Charson comorbidity index of 0, patients with a Charlson comorbidity index ≥ 2 had lower MCS (β=-1.183, P=0.007). In the past 12 months, 648 (31.9%), 143 (7.0%), 406 (20.0%), 680 (33.4%), 343 (16.9%), 681 (33.5%), 170 (8.4%) patients had used non-steroid anti-inflammatory drugs (NSAIDs), acetaminophen, glucosamine/chondroitin formulations, physical therapy, articular cavity puncture injection, traditional Chinese medicine treatment and exercise therapy, respectively. Total of 451 patients (22.2%) received monotherapy and 889 patients (43.7%) received combination therapy. Conclusions: The major non-surgical treatment methods for patients with knee osteoarthritis in Beijing are NSAIDs, physiotherapy and traditional Chinese medicine. Combination therapy is used more frequently than monotherapy. Physical quality of life is related to gender, age, education, severity of symptoms and treatment, while mental quality of life is related to occupational labor and comorbidities.

Abstract
BACKGROUND SCARA5 has been demonstrated to be a tumor suppressor gene, with its expression downregulated in many cancer types. However, only few studies have investigated its role in colorectal cancer (CRC). The current study evaluated SCARA5 expression levels in CRC and its potential value as a diagnostic biomarker for CRC. METHODS Data were downloaded from the TCGA, GEO, and Oncomine databases to evaluate SCARA5 mRNA expression levels in CRC. The prognosis value of SCARA5 was assessed using the online tool Cutoff Finder via the Kaplan-Meier plotter (n = 484). Immunohistochemistry was performed to analyze and compare the SCARA5 protein expression levels in CRC and normal tissues from 67 CRC clinical specimens. Relevant CRC CNV data were downloaded from TCGA and cBioPortal for Cancer Genomics databases to assess the associated genetic alterations. GSEA was used to explore the underlying molecular mechanisms of SCARA5. The correlation between SCARA5 mRNA levels and cell cycle-associated genes was explored using GEPIA database. RESULTS SCARA5 mRNA levels were found to be downregulated in CRC tissues compared with normal tissues. Survival analysis showed that low SCARA5 expression was associated with poor prognosis. These results were validated in clinical specimens, wherein the SCARA5 protein levels were significantly downregulated in CRC tissues compared with paracarcinoma tissues. Deep deletion was the most common genetic alteration and was consistent with the downregulated SCARA5 expression in CRC tissues. GSEA indicated that the gene sets of CELL CYCLE, G2M CHECKPOINT, and E2F TARGETS were negatively related to SCARA5 mRNA expression. GEPIA indicated that the mRNA expression of some cell cycle-associated genes was negatively correlated with that of SCARA5 in CRC. CONCLUSIONS Thus, SCARA5 may act as a human cancer suppressor gene in CRC, and its expression level may be a reliable adjuvant parameter to diagnose CRC and predict tumor metastasis and prognosis.

Abstract
To study the key aroma components and flavor profile differences of Cheddar cheese with different maturity and from different countries, the flavor components of 25 imported commercial Cheddar cheese samples in the China market were determined by gas chromatography-mass spectrometry. The quality and quantity of 40 flavor compounds were analyzed by gas chromatography-olfactometry among 71 aroma compounds determined by gas chromatography-mass spectrometry. Combined with odor activity value calculation, principal component analysis (PCA) was conducted to analyze the relationship among 26 flavor compounds with odor activity values >1 and the maturity of Cheddar cheese. The PCA results showed significant differences between the group of mild Cheddar cheese and the groups of medium Cheddar cheese and mature Cheddar cheese, and no significant differences were observed between medium Cheddar cheese and mature Cheddar cheese. According to the results of PCA and consumers' preference test, representative Cheddar cheese samples with different ripening times were selected for the flavor profile analysis. Partial least squares regression analysis was conducted to obtain the relationship between sensory properties and flavor compounds of different Cheddar cheeses. Based on partial least squares regression analysis, 1-octen-3-one, hexanal, acetic acid, 3-methylindole, and acetoin were positively correlated with milky, sour, and yogurt of mild Cheddar cheese. Dimethyl trisulfide, phenylacetaldehyde, ethyl caproate, octanoic acid, and furaneol and other compounds were positively correlated with fruity, caramel, rancid, and nutty notes of the medium and mature Cheddar cheeses.

Abstract
Objective: To investigate the microbiological test, antibiotic sensitivity and surgical treatment of periprosthetic joint infection(PJI) cases in post total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Methods: A retrospective cross-sectional survey was conducted on 318 patients who underwent THA or TKA in 9 clinical centers in Beijing from January 2014 to December 2016.The data of microbiology, antibiotic sensitivity and surgical treatment were collected.The average age of patients was (62.3±13.1) years old (range: 21-86 years old), including 145 males and 173 females.The body mass index was (25.6±3.8) kg/m (2) (range: 15.6-38.1 kg/m(2)). Results: In total, 318 patients had microorganisms detected by periprosthetic tissue culture or synovial fluid culture, 209 cases (65.7%) had Gram-positive bacteria, 29 cases (9.1%) had Gram-negative bacteria, 10 cases (3.1%) had fungi, 3 cases (0.9%) had non-tuberculous mycobacteria, 72 cases (22.6%) were negative, 69 cases (21.7%) had methicillin-resistant bacteria. The antibiotic sensitivity results showed that the overall resistance rate of penicillin, cefuroxime, amoxicillin+clavulanic acid was 79.9%, 69.9%, and 68.1%, respectively; meropenem, vancomycin, and linezolid resistance rate was 0. For the treatment methods of hip and knee PJI, two-stage revision surgery acounted for 72.9% (108/148) and 64.1% (109/170), respectively. One-stage revision surgery accounted for 21.6% (32/148) and 7.6% (13/170), and open debridement surgery accounted for 4.7%(7/148) and 26.4% (45/170). Conclusions: Gram-positive bacteria was still the main pathogen of PJI.The methicillin-resistant bacteria and rare bacteria should be payed attention to. The Majority of hip and knee PJI cases were treated by two-stage revision surgery.

Abstract
OBJECTIVE To evaluate the accuracy and analysis of the influencing factors of the tibia prosthetic coronal alignment after total knee arthroplasty without tibia extramedullary cutting guide. METHODS In the study, 76 patients (96 knees) who had primary total knee arthroplasty in Peking University First Hospital from February 2012 to April 2016 were selected retrospectively. All of the cases were performed by the same experienced orthopedic surgeon team. The patients were divided into 2 groups randomly: tibia cutting without guide group and tibia cutting with extramedullary guide group. Lower extremity standard anterior and posterior X-ray films of the knees were taken before and after surgery, and the anatomical tibial angle (AT), the posterior slope angle (PSA) before and after surgery, the tibia component angle (TCA) were measured in the X-ray films. We also recorded the beginning and finishing time of the operation, the operation sequence of the day respectively at the same time. The data were analyzed by correlation analysis, t test and chi square test between the two groups. RESULTS The age, gender, body mass index, AT/PSA before the surgery and TCA/PSA after the surgery of the two groups were no significant differences (P>0.05). The rate of 90-TCA≥ 3° was 31.5% (17 knees) and 31% (12 knees) respectively, there were no significant differences (P=0.956) between the two groups. The postoperative TCA of two groups was not correlated with age, gender, body mass index (BMI), operation side (P>0.05), there was also no correlation between the postoperative TCA and the start time of the operation, the whole operation time, and the operation sequence of the day (P>0.05). The two groups were divided into subgroups according to 90-AT before the operation (0°≤90-AT<3°, 3°≤90-AT<5°, 5°≤90-AT<8°, 90-AT≥8°), and there was no difference among them. But we found there was a much higher rate of 90-TCA<3° in the group without cutting guide than the group with extramedullary guide when 90-AT≥8° before the surgery (the rates were 71.4 % and 42.9%, P<0.05). CONCLUSION There is no significant difference of the tibia prosthetic coronal alignment accuracy between the tibia cutting without guide and the traditional extramedullary guided bone cutting by experienced surgeons. Only if when patients already have suffered severe malformation of knee joint (90-AT≥8°) before the operation, tibia cutting without cutting guide is more effective to rectify the tibia prosthetic coronal alignment.

Abstract
OBJECTIVE To investigate whether endogenous hydrogen sulfide (H2S) was involved in the pathogenesis of osteoarthritis (OA) and its underlying mechanism, to detect H2S and its synthases expression in knee cartilage in patients diagnosed with different severity of OA, and to explore the transcription and expression of gene MMP-13 in chondrocytes treated with IL-1β or H2S. METHODS Synovial fluids of the in-patients with different severity of OA hospitalized in Peking University First Hospital were collected for measurement of H2S content using methylene blue assay. Articular cartilages of the patients who underwent knee arthroplasty were collected for the cell culture of relatively normal chondrocytes. The chondrocytes were cultured to the P3 generation and H2S molecular probes were used for detection of endogenous H2S generation in the chondrocytes. Immunocytochemistry was used to detect the localization of H2S synthases including cystathionine β-synthase (CBS), cystathionine-γ-lyase (CSE), and mercaptopyruvate sulfurtransferase (MPST) in OA chondrocytes. Western blot was used to quantify the protein expressions of CSE, MPST, and CBS in cartilage tissues of the patients who were diagnosed with OA and underwent knee arthroplasty. The relatively normal human chondrocytes were cultured to passage 3 and then divided into 4 groups for different treatments: (1)the normal control group, no reagent was added; (2)the IL-1β group, 5 μg/L of IL-1β was added; (3)the IL-1β+H2S group, 200 μmol/L of NaHS was added 30 min before adding 5 μg/L of IL-1β;(4)the H2S group, 200 μmol/L of NaHS was added. The transcription and expression of gene MMP-13 in chondrocytes of each group were determined with Real-time PCR and Western blot, respectively. And the total NF-κB p65 and phosphorylated NF-κB p65 in chondrocytes were detected with Western blot. RESULTS The content of H2S in the synovial fluid of degenerative knee was (14.3±3.3) μmol/L. Expressions of endogenous H2S and its synthases including CBS, CSE and MPST were present in the cytoplasm of chondrocytes.CSE protein expression in Grade 3 (defined by outerbridge grading) cartilage tissues was significantly increased as compared with that of Grade 1 cartilage tissues (1.67±0.09 vs. 1.26±0.11, P< 0.05). However, no significant difference of CBS or MPST expression among the different groups was observed. The expression of MMP-13 protein in the IL-1βgroup was significantly higher than that in the normal chondrocytes (1.87±0.67 vs. 0.22±0.10, P<0.05), and that in the IL-1β+H2S group was significantly decreased than that in the IL-1β group (0.55±0.11 vs. 1.87±0.67, P< 0.05), and that in the H2S group had no significant difference compared with that in the normal control group. The transcription of MMP-13 protein in the IL-1β group was significantly higher than that in the normal chondrocytes (31.40±0.31 vs. 1.00±0.00, P<0.05), and that in the IL-1β+H2S group was significantly decreased than that in the IL-1β group (24.41±1.28 vs. 31.40±0.31, P<0.05), and that in the H2S group had no significant difference compared with that in the normal control group. The total NF-κB p65 in the IL-1β group was significantly higher than that in the normal chondrocytes (2.13±0.08 vs. 0.73±0.08, P< 0.05), and that in the IL-1β+H2S group was significantly decreased than that in the IL-1β group (1.24±0.13 vs. 2.13±0.08, P<0.05), and that in the H2S group had no significant difference compared with that in the normal control group. The phosphorylated NF-κB p65 in IL-1β group was significantly higher than that in the normal chondrocytes (1.30±0.13 vs. 0.19±0.04, P<0.05), and that in IL-1β+H2S group was significantly decreased than that in the IL-1β group (0.92±0.26 vs. 1.30±0.13, P<0.05), and that in the H2S group had no significant difference compared with that in the normal control group. CONCLUSION H2S affected the cartilage degeneration by partly inhibiting the degradation of extracellular matrix.

Abstract
The shikimate pathway enzyme 5-enopyruvylshikimate-3-phosphate synthase (EPSPS) is the target of the broad spectrum herbicide glyphosate. A novel aroA gene encoding an EPSPS from Pantoea sp was identified and subcloned into the pET-28a vector to construct the recombinant pET-AroAPantoea sp plasmid. Amino acid sequence analysis indicated that AroAPantoea sp is a class I AroA enzyme. When expressed in Escherichia coli, it conveyed high tolerance to glyphosate. AroAPantoea sp may be used to generate transgenic glyphosate-tolerant plants.

Abstract
OBJECTIVE To investigate the efficacy of single time intra-articular different concentration of allogeneic bone marrow mesenchymal stem cells (BM-MSCs) injection in the treatment of Sprague-Dawley (SD) rat model of osteoarthritis (OA). METHODS In the study, 32 SD rats were equally randomized into 4 groups: control group, high concentration group (1×10(7)/mL BM-MSCs), low concentration group (5×10(6)/mL BM-MSCs) and high vs. low concentration group. The two knees of each rat were set up to a pair. The induction of OA was performed surgically randomly at one side in model group, and bilaterally in the other groups, which were through anterior cruciate ligament transaction (ACLT) and medial meniscus excising. After the operation, the SD rats were allowed free movement. Four weeks later, different concentrations of allogeneic BM-MSCs isolated from the SD rats, expanded in vitro and suspended in phosphate buffered solution (PBS) were delivered in the articular cavity of both knees; PBS was used as the control. After injection, we excised the femoral nerve and sciatic nerve to disuse the low limb. The cartilage histological sections of knees were scored by Mankin scoring system to assess the severity of the pathology. mRNA of collagen II was detected by real time polymerase chain reaction (RT-PCR). eGFP was detected by fluorescence microscope. Assessments were carried out 4 weeks after the operation in model group, and 3 weeks after injection in the other groups. RESULTS Mankin scores of the BM-MSCs side and control side were 6.60±0.40 vs. 10.00±0.32 in low concentration group (P<0.05), and 5.40±0.51 vs. 9.60 ±0.51 in high concentration group (P<0.05). Mankin scores of high vs. low concentration group were 6.40±0.51 vs. 7.60±0.75 (P>0.05). mRNA expression of collagen II of the BM-MSCs side in low concentration group was 106%±1% in contrast to the control side. As in high concentration group it was 108%±1%, and 102%±1% in high vs. low concentration group. Labeled BM-MSCs were detected unexpectedly in the synovial membrane but not in cartilage tissue three weeks from injection. CONCLUSION BM-MSCs could promote cartilage repair and inhibit OA progression through a trophic mechanism. There was no difference between the two concentrations.

Abstract
We have surgically treated two patients with cerebral cysticercosis, which were pre-operatively unexpected due to unusual CT and MRI manifestations. A 24 year old chinese farmer with intermittent severe headache for 6 years was examined by CT and MRI. A huge cystic lesion with same density or intensities to CSF occupied retroclival posterior fossa to upper cervical spinal canal and displaced neural structures backwardly. By suboccipital craniectomy, watery clear cyst fluid of 44ml was aspirated and the shrunken cyst was pulled out with ease. It was unable to predict until an electron microscopic study, which revealed a larva with three layers of microvilli, vesicular tegmentum and infrategmental muscle bundles and vesicles. The findings were same to those of racemose cysticercus of human brain. Giant cysts of cysticercosis were infrequently present supratentorially, although infratentorial or basal cysticercosis were racemose and small. The present case may be the first case of a huge cyst of cysticercosis in posterior fossa. A 44 year old Japanese businessman with 15 years history of general convulsion underwent craniotomy due to a small, but growing cystic granulomatous mass in right inferior frontal gyrus. The CT scan examined at 3 years after his first general convulsion revealed a small round low density mass, 5mm in diameter, in right frontal lobe and its wall was weakly enhanced by contrast media. The follow-up CT scans and MRIs revealed that the enhancing cystic mass became thick and deformed, and perifocal edema came to evident and progressed stepwise by attacks of general convulsions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Carbon fiber electrodes combined with semi-differential voltammetry were used to determine endogenous monoamine metabolites and ascorbic acid (AA). These electrodes treated by a new electrochemical procedure (30 microA for 30 s, then -2 V for 10 s) showed a significant improvement on the sensitivity and selectivity. In the rat corpus striatum, these electrodes allowed a distinct separation and continuous detection of AA, 3, 4-dihydroxyphenylacetic acid (DOPAC), and 5-hydroxyindoleacetic acid (5-HIAA) simultaneously. The normal striatal levels of AA, DOPAC, and 5-HIAA were found to be 168.2 +/- 19.5, 21.4 +/- 3.9, and 3.3 +/- 0.5 mumol.L-1. Our method is credible for detecting the changes of monoamine metabolite contents induced by pharmacologic manipulations.
