Abstract
Objective: To explore and compare the reference ranges of four coagulation tests in normal pregnant women during early and late pregnancy and the influence of age. Methods: Values of four coagulation tests from 4 974 pregnant women, who gave single birth at Peking University First Hospital, Obstetrics and Gynecology Hospital of Fudan University, West China Second University Hospital, Peking University Third Hospital and Shengjing Hospital of China Medical University from February 2017 to July 2020, were measured and analyzed in this study, including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and thrombin time (TT). The four normal reference ranges of coagulation during early and late pregnancy phases were expressed as P2.5-P97.5. The difference of two pregnancy phases was compared by non-parametric test of two related samples. And the difference between pregnant women of advanced and non-advanced age in the same pregnancy phase was compared by independent sample non-parametric test. Chi-square test was used to compare the incidence of pregnancy complications in different coagulation reference ranges. Results: The reference ranges of PT of normal pregnant women's early and late pregnancy were 10.0-13.9 s and 9.6-12.3 s, the reference ranges of APTT were 22.6-35.3 s and 22.4-30.9 s, the reference ranges of Fib were 2.4-5.0 g/L and 3.0-5.7 g/L, the reference ranges of TT were 12.0-19.0 s and 11.5-18.4 s. Compared with early pregnancy, PT, APTT and TT shortened significantly, while the Fib significantly increased in late pregnancy (all P<0.001). PT, APTT and TT of advanced and non-advanced age pregnant women were significantly different (all P<0.01). Compared with the ranges of non-pregnant population, more pregnant women were included in the normal pregnant reference ranges of PT in early pregnancy and APTT in the early and late pregnancy, while the incidence of pregnancy complications had no significant differences (all P>0.05). The incidence of fetal distress was higher and the incidence of preterm birth was lower in the reference range of PT in late pregnancy. The incidence of gestational diabetes mellitus was higher in the early and late gestational Fib reference ranges, and the incidence of hypertensive disorders in pregnancy was higher in the late gestational Fib reference range (all P<0.05). Conclusions: The coagulation function of pregnant women increases significantly with the growth of pregnancy, and there is a significant difference between advanced significantly and non-advanced age pregnant women. The recommended ranges of normal pregnant women's early and late pregnancy PT are 10.0-13.9 s and 9.6-12.3 s, the recommended ranges of APTT are 22.6-35.3 s and 22.4-30.9 s, the recommended ranges of TT are 12.0-19.0 s and 11.5-18.4 s. The appropriate ranges of normal pregnant women's early and late pregnancy Fib still need further exploration.

Abstract
Objective: To investigate the clinicopathologic features and outcome of myositis in patients with advanced non-small cell lung cancer treated with immune checkpoint inhibitors. Methods: The patients diagnosed with immune checkpoint inhibitor-related (ICI) myositis in the database of Respiratory Pathology Center of The First Affiliated Hospital, Guangzhou Medical University from June 2019 to December 2020 were retrospectively analyzed. We reported the muscle histology and main clinical manifestations of the patients in this study. Seven patients with advanced non-small cell lung cancer and ICI related myositis were examined; all of the patients were male, with a median age of 64 (range 42-79) years. Results: All seven patients developed myositis under therapy (three for pembrolizumab, three for sintilimab, and one for camrelizumab). Median delay between ICI initiation and myositis onset was 45 (range 15-176) days. Clinical manifestations were dominated by acute or subacute myalgia and limb weakness. Four patients had evidence of myocarditis. In all of the 7 patients, creatine kinase levels were elevated (median 2 354.4, range 468.6-19 709.2 U/L), while myositis-associated antibodies Ro-52 were positive in four patients. Muscle biopsy showed evident multifocal necrotic myofibers and infiltration of inflammation in two patients. Other patients only showed non-specific endomysial inflammation. Infiltration of inflammation mainly consisted of CD8+ T cells and CD68+ histocytes. After the identification of ICI related myositis, ICI treatment was withdrawn in all patients; 6 patients received corticosteroids therapy. All patients had shown marked clinical improvement. Conclusions: ICI myositis presents with remarkably homogeneous and unique clinicopathologic features, and half of the patients exhibit heightened risk for adverse cardiovascular events, which can be life-threatening if not treated in time. Timely identification of these patients, ICI withdrawal and rapid initiation of corticosteroids therapy can significantly improve patient outcome and/or save patients' lives.

Abstract
Duplex polymerase chain reaction with lateral flow dipsticks (duplex PCR-LFD) was developed for the simultaneous detection of beta-lactamase Klebsiella pneumoniae carbapenemase (blaKPC ) and beta-lactamase New Dehli metallo-beta-lactamase (blaNDM ) genes in body fluid samples. This method was validated using well-characterized isolates. The assessment of the specificity of duplex PCR-LFD showed that there was no cross-reactivity with other targets. The detection limit of the duplex PCR-LFD assay was 20 CFU per ml for blaKPC and blaNDM . Among 177 sterile body fluid samples tested by the duplex PCR-LFD assay, 40 were blaKPC -positive and five were blaNDM -positive. The results obtained from 122 corresponding Gram-negative bacteria which were isolated from these clinical samples and tested by duplex PCR-LFD assay showed that there were 37 strains carrying blaKPC genes in 40 blaKPC -positive samples and three strains carrying blaNDM genes in five blaNDM -positive samples. Statistical analysis indicated that there was no significant difference between the direct detection of blaKPC and blaNDM genes in clinical sterile body fluid samples and their corresponding clinical isolates. Therefore, duplex PCR-LFD can be effective for the simultaneous detection of blaKPC and blaNDM in clinical isolates and directly from clinical samples, which may be helpful for the administration of appropriate antimicrobial treatment.

Abstract
Objective: To evaluate the value of transbronchial lung cryobiopsy (TBCB) in pathological diagnosis for diffuse lung disease. Methods: The clinicopathological data of 173 patients from the first affiliated hospital of Guangzhou medical university between Jaunary 2017 and June 2019 with transbronchial lung cryobiopsy of diffuse lung disease were retrospectively analyzed and summarized with review. Among 173 cases, TBCB and conventional transbronchial lung biopsy (TBLB) were performed in 54 patients. The size of biopsy samples and diagnostic yield were compared. Results: Among 173 cases, the diagnostic yield was 85.54% (148/173) , 160 (92.49%) cases provided definite diagnosis and valuable pathological results, according to age, sex, occupation, past history, contact history, smoking history, laboratory serology and imaging findings. Among 160 cases, there were 72 cases of known etiology (45.00%), 27 cases of idiopathic interstitial pneumonia (16.88%), 7 cases of granulomatous lesions (4.38%) and 54 cases of other types (33.75%). With TBCB and TBLB in 54 patients, the specimens sizes of TBCB and TBLB were (3.3±1.3) mm(2) and (1.0±0.3) mm(2) respectively (t'=12.67 P<0.01) . The diagnostic yields of TBCB and TBLB were 81.48% (44/54) and 42.59% (23/54) respectively (χ(2)=17.33, P<0.01) . The diagnostic yields of TBCB and TBLB for interstitial lung diseases were 48.15% (26/54) and 5.56% (3/54) respectively (χ(2)=24.94, P<0.01) . However, the diagnostic yields of TBCB and TBLB for the other diffuse lung disease except interstitial lung diseases were 33.33% (18/54) and 37.04% (20/54) respectively, with no significant difference (χ(2)=0.1624, P=0.687). Conclusion: Compared with TBLB, TBCB has obvious advantages and application value in the diagnosis of diffuse pulmonary diseases, especially interstitial pulmonary diseases.

Abstract
Objective: To improve the clinical recognition of eosinophilic granulomatosis with polyangiitis(EGPA) in clinical manifestations, diagnosis and treatment. Methods: The clinical manifestations, pathological characteristic, imaging manifestations, diagnosis and the therapy of three patients with EGPA were presented. Results: These 3 patients had asthma-like symptoms and extrapulmonary manifestations of systemic vasculitis. They were 20, 40 and 44 years old. All of them were female.They denied exposure or contact. Chest radiographic examination showed that the most common features were nodule shadow and tree-in-bud in the lung. The pathological manifestation was characterized by hypereosinophilia, high total IgE(over 300 KU/L) and high CRP(over 14.1mg/L). The FeNO of 2 patients was over 100ppb. The ANCA of these 3 patients was negative. The pulmonary pathology was observed had eosinophil infiltration in the alveolar, interstitial and vessel for 3 cases. The clinical manifestations were nonspecific. All patients were treated by glucocorticoid and immune-inhibitor(alkylating agents or purine synthesis inhibitors) therapy. Because patients were complicated with other organs involved, they needed long-time treatment. Conclusions: This disease is diverse and complex, with a lack of pathognomonic symptoms. We should highly suspect eosinophilic granulomatosis with polyangiitis, when the patients present severe asthma and eosinophilia. Early detection, early treatment, and the prognosis could be better.

Abstract
Oxaliplatin is commonly used in managing malignancy, including colorectal cancer. While treatment often fails due to decreased drug sensitivity, the mechanisms involved are not clear. In this study, we investigate how exosomal miR-19b participates in oxaliplatin sensitivity and then prove that miR-19b down-regulates oxaliplatin sensitivity of sw480 cells. We found that suppressing the secretion of exosomal miR-19b with gw4869 promotes sw480 cell oxaliplatin sensitivity. Our combined results demonstrate for the first time that miR-19b regulates the oxaliplatin sensitivity of sw480 cells and provides a unique mechanism mediated by gw4869 to modulate oxaliplatin sensitivity by suppressing exosomal miR-19b release.

Abstract
Objective: To report a case of the pulmonary surfactant protein(SP) adenosine triphosphate-binding-cassette-A3 (ABCA3) gene mutations in infant congenital interstitial lung disease(ILD), and review the related literature, to investigate the relationships of ABCA3 gene mutation associated with ILD in infants. Method: A 6-months-old boy was hospitalized in the department of Pediatrics of the First Affiliated Hospital of Guangzhou Medical University. The clinical, radiological, histological information from transbronchial lung biopsy (TBLB) and genetic testing in this case was analyzed; 12 reports retrieved on literature search at Pubmed, OVID databases from 2004 to 2015 by using the ABCA3 as keyword were reviewed and analyzed. Result: (1)The patient, a 6-months-old boy, had progressive tachypnea and dyspnea since 4 months old. Physical examination on admission revealed respiratory rate of 78 times/min , heart rate of 187 times/min, SpO2 0.93(mask oxygen-inspiration with 6 L/min), scattered fine moist crackles could be heard over the both lungs, clubbing fingers were found. High-resolution computed tomography(HRCT) revealed diffuse ground-glass opacity, interlobular and intralobular septal thickening. Lung biopsies showed evidences of the alveolar cavity atelectatic changes and interstitial fibrosis. SP-A and SP-B were negative in immunohistochemical stainting. SP-related gene sequence analysis found that there was compound heterozygous missense mutation of ABCA3 gene in c. 1942A>G, c.2701-33G>C and c. 991-105C>A. (2)The review of related literature found that totally 12 cases were reported. The main manifestations were progressive tachypnea and dyspnea, age of onset was between birth and 4 years of age. The imaging characteristics of chest HRCT revealed diffuse infiltration or diffuse ground-glass pattern in the lung. PROGNOSIS 6 cases died, and 6 cases survived, including 4 cases with pulmonary function disturbance to different degrees; 12 cases had ABCA3 gene mutations, 9 cases had composite ABCA3 gene mutations, in 11 cases the mutation occured in the exon of coding region, in 1 case in the intron, 9 cases had heterozygous mutations, 3 cases had homozygous mutations. Conclusion: The main phenotypes of ABCA3 mutation associated with ILD were full term neonatal respiratory distress syndrome or progressive tachypnea or dyspnea unexplained in infants. The chest HRCT showed two diffuse pulmonary interstitial changes. ABCA3 mutation mainly was multi-site composite mutations and heterozygous mutations in the exon of coding region.

Abstract
This study evaluates the relationship between the genotype and milk protein components in goats. Milk samples were collected from cloned goats and normal white goats during different postpartum (or abortion) phases. Two cloned goats, originated from the same somatic line of goat mammary gland epithelial cells, and three sexually reproduced normal white goats with no genetic relationships were used as the control. The goats were phylogenetically analyzed by polymerase chain reaction-restriction fragment length polymorphism. The milk protein components were identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis. The results indicated that despite the genetic fingerprints being identical, the milk protein composition differed between the two cloned goats. The casein content of cloned goat C-50 was significantly higher than that of cloned goat C-4. Conversely, although the genetic fingerprints of the normal white goats N-1, N-2, and N-3 were not identical, the milk protein profiles did not differ significantly in their milk samples (obtained on postpartum day 15, 20, 25, 30, and 150). These results indicated an association between milk protein phenotypes and genetic polymorphisms, epigenetic regulation, and/or non-chromosomal factors. This study extends the knowledge of goat milk protein polymorphisms, and provides new strategies for the breeding of high milk-yielding goats.

Abstract
OBJECTIVES Psychotic symptoms are commonly observed among heroin users. Low serum brain-derived neurotrophic factor (BDNF) levels have been reported in schizophrenia and psychosis; however, studies assessing the relationship between serum BDNF levels and psychotic symptoms in heroin dependence are lacking. METHOD A total of 31 heroin-dependent patients who had never experienced psychotic symptoms during heroin consumption and 21 patients with a history of psychotic symptoms were consecutively recruited. We measured by enzyme-linked immunosorbent assay (ELISA) serum BDNF levels during early abstinence. A gender- and age-matched sample of healthy controls was also recruited and underwent measurement of BDNF. RESULTS BDNF levels were significantly lower in patients with psychotic symptoms than in those without psychotic symptoms (P<0.001). BDNF levels were not found to be correlated with sex, age, age of onset, duration of heroin use, average daily dose of heroin use, frequency of heroin use, SDS scores, BAI scores and BDI scores in the psychotic subsamples (all P>0.05). CONCLUSIONS Our findings suggest that heroin-dependent patients with psychotic symptoms share some of the neurotrophic insult that characterizes schizophrenia and psychosis.

Abstract
The functional effect of platelet membrane glycoprotein Ia ( GPIa) gene 807C/T polymorphism in unstable angina pectoris (UAP) pathogenesis was investigated in Chinese Han individuals. Collagen type I-induced platelet aggregation was measured in 33 healthy subjects. Plasma levels of α-granule membrane protein (GMP-140) were measured in 33 healthy subjects and in 35 patients with recentonset angina at rest within 24 h of hospitalization. Platelet membrane GPIa gene 807C/T polymorphism was determined in all subjects. Lag-time before 30% platelet aggregation was significantly longer in CC genotype than in TC genotype healthy subjects, although there was no significant difference in maximal platelet aggregation between healthy subjects with either genotype. Plasma GMP-140 levels were significantly higher in TC genotype patients compared with CC genotype patients or healthy subjects; a significant difference was also observed between the latter two groups. It was concluded that rapid initiation of collagen-induced platelet aggregation may be associated with the platelet membrane GPIa T807 allele, which may be important in UAP pathogenesis.

Abstract
The aims of this study are to investigate the cytokine, chemokine and adhesion molecule profiles in cerebrospinal fluid from patients with neuropsychiatric systemic lupus erythematosus and systemic lupus erythematosus with central nervous system infection. Experimental sets were established which included 108 patients and 132 cerebrospinal fluid samples. The patients were grouped as neuropsychiatric systemic lupus erythematosus (n = 54), systemic lupus erythematosus with central nervous system infection (n = 16), systemic lupus erythematosus controls (n=20), and non-inflammatory neurological disease (n=18). The dynamic changes of 21 patients in the neuropsychiatric systemic lupus erythematosus group before and after induction therapy were further analyzed. IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, TNFα, IFNγ, IP-10, MCP-1, RANTES, VCAM-1, and P-selectin were measured in cerebrospinal fluid samples by using a fluorescent bead-based assay. Cerebrospinal fluid levels of IL-8, MCP-1, P-selectin and VCAM-1 were significantly increased in neuropsychiatric systemic lupus erythematosus compared with systemic lupus erythematosus controls. IL-6, IL-17, IL-8 and VCAM-1 were higher in systemic lupus erythematosus with central nervous system infection than in systemic lupus erythematosus controls. Among systemic lupus erythematosus with central nervous system infection, the IL-6, IL-17, IL-8 and IP-10 levels were higher than those in neuropsychiatric systemic lupus erythematosus. After sufficient induction therapy, IL-8, MCP-1, P-selectin, VCAM-1 and IL-6 in patients with neuropsychiatric systemic lupus erythematosus decreased significantly. Levels of all molecules tested in non-inflammatory central nervous system disease were not different from those of systemic lupus erythematosus controls. From our data, the intrathecal cytokine/chemokine profile is different among patients with neuropsychiatric systemic lupus erythematosus, systemic lupus erythematosus complicated with central nervous system infection and systemic lupus erythematosus controls. IL-8, MCP-1, VCAM-1, P-selectin and IL-6 in cerebrospinal fluid are effective parameters to monitor neuropsychiatric systemic lupus erythematosus disease activity and response to treatment. Significantly elevated IL-17, IL-6, and to a lesser extent, IL-8, favors central nervous system infection in systemic lupus erythematosus. Lupus (2010) 19, 689—695.

Abstract
OBJECTIVE Antikinectin autoantibody has recently been identified as a potential biomarker in Behçet's disease (BD). Here, we established an enzyme-linked immunosorbent assay (ELISA) and an indirect immunofluorescent assay (IFA) for detecting this antibody. The clinical significance of antikinectin was investigated. METHODS Partial or full-length cloning for human kinectin in prokaryotic or eukaryotic system was carried out. Three fragments covered kinectin coding sequence were used to establish ELISA. Full-length kinectin overexpressed HepG2 cells were used as a substrate for IFA. Serum samples from BD (n = 46), systemic lupus erythematosus SLE, n = 16), rheumatoid arthritis (RA, n = 160, ankylosing spondylitis (AS, n = 14), primary Sjörgen syndrome (pSS, n = 12), mixed connective tissue disease (MCTD, n = 8), and healthy donors (n = 51) were examined. RESULTS Good measurement consistency between IFA and ELISA (p < 0.001) and previous immunoprecipitation assay (p = 0.011) was found. Antikinectin was found not only in 32.6% (IFA) to 41.3% (ELISA) BD patients but was also identified in pSS, SLE, MCTD, and RA with prevalence ranging from 12.5% to 25%. Nevertheless, the titer of antikinectin (ELISA) is statistically higher in BD compared to other autoimmune connective tissue diseases (p = 0.0286). Antikinectin was found exclusively among complete form of BD (p < 0.001), but there was no correlation with specific clinical manifestations. CONCLUSIONS We confirmed the previous observation that antikinectin is related to BD, especially in the complete form of disease. The specificity and predictive values are moderate.

Abstract
The purpose of our study was to clarify the prognosis of lymphoepithelioma-like carcinoma (LELC) of the lung, which is rare. We analyzed the clinicopathologic features of 32 cases of pulmonary LELC and compared the cases with 84 cases of pulmonary non-LELC with available long-term follow-up information. The results show that LELC of the lung as a distinct entity has a better prognosis than non-LELC. We found a significant difference in the survival rates between patients with LELC and patients with non-LELC in stage II and stages III and IV, respectively. Tumor recurrence and necrosis (5% or more of tumor) are associated with a poor prognosis. It seems that the histologic typing (Regaud type and Schmincke type) of pulmonary LELC is of no clinical value.

Abstract
A prospective echocardiographic and clinical study was performed on 84 Chinese patients with systemic lupus erythematosus (SLE) and 99 controls to investigate the prevalence and the mechanism of pulmonary hypertension (PH) in SLE. Comparison between Doppler estimation and catheterization measurement was made in 12 cases to validate the predictive method. Compared to normal subjects, lupus patients had significantly increased systolic pulmonary artery pressure (SPAP) (29.59 +/- 12.52 vs 19.64 +/- 5.82, P < 0.001), mean pulmonary artery pressure (MPAP) (15.11 +/- 7.36 vs 10.21 +/- 4.72, P < 0.001) and total pulmonary resistance (TPR) (315.85 +/- 190.65 vs 220.37 +/- 55.92, P < 0.001). Nine of the 84 patients presented PH, defined as SPAP < 30 mmHg and MPAP > 20 mmHg. Pulmonary hypertensive patients had higher serum endothelin (ET) than non-pulmonary hypertensive patients, were more commonly in active stages, and presented Raynaud's phenomenon and rheumatoid factors. ET level was correlated with echocardiographic pulmonary pressure. Pulmonary hypertension commonly occurs in Chinese patients with SLE (11%), and it correlates with the lupus activity and the elevation of serum endothelin.

Abstract
The Lidar In-Space Technology Experiment (LITE) was flown on STS-64 in September 1994. The LITE employed a Nd:YAG laser operating at 1064, 532, and 355 nm to study the Earth's lower atmosphere. In this paper we investigate the nighttime stratospheric aerosol and temperature measurements derived from the 532- and 355-nm channels. The observations are compared with lidar observations obtained at Arecibo Observatory, Puerto Rico, and Starfire Optical Range, New Mexico, and with balloonsondes launched from the San Juan and Albuquerque airports. The backscatter ratios derived from the LITE and Arecibo data between 15 and 30 km differ by less than 5%. The Angstrom coefficients of the stratospheric aerosols derived from the 532- and 355-nm LITE channels exhibited only slight variation in altitude. The mean value between 15 and 30 km derived from three different orbital segments at approximately 20 degrees N and 35 degrees N was 1.7. The mean standard deviation was approximately 0.3. Temperature profiles were derived from the LITE data by correcting the 355-nm channel for aerosol scattering with the 532-nm signal and an assumed Angstrom coefficient. The rms differences between the corrected profiles and the balloonsonde data were as low as 2 K in the 15-30-km height range. The results were not particularly sensitive to the choice of the Angstrom coefficient and suggest that accurate temperature profiles can be derived from the LITE data in the upper troposphere and lower stratosphere provided that the aerosol loading is light.

Abstract
Labial salivary gland biopsy (LSG-B) along with Schirmer test and kerato-conjunctival staining with fluorescein dye was performed in 196 patients with suspected Sjogren's syndrome (SS). Of the 196 patients, 117 were found to have 2 or more lymphocytic focus scores (LFS/4mm2) on their LSG-B specimens. 92 of them having keratoconjunctivitis sicca (KCS) as well met the diagnostic criteria of SS. Among the cases (25) without KCS, 16 with another CTD were diagnosed as secondary SS. 9 cases were classified as probable primary SS in this study because they had clinical manifestations of SS. Of the 11 cases with KCS only, 6 with another CTD were diagnosed as secondary SS; 5 befitted primary SS for abnormal findings on sialography. We also found that lymphocytic infiltration in LSG-B was much more severe in primary SS than in secondary SS; this could be attributed to the use of immunotherapy for the accompanying CTD in secondary SS. There was good association in our study between the severity of lymphocytic infiltration and systemic involvement.

Abstract
By using immunoblotting technique (IBT) and salt extracts of rabbit thymus powder as antigen, we detected autoantibodies against polypeptides of extractable nuclear antigen (ENA) in 358 patients with different rheumatic diseases. It was found that antibodies against polypeptides with molecular weights of 13,900 dalton (designated as D') and 11,500 dalton (designated as E) could be detected only in mixed connective tissue disease (MCTD) with a positive rate of 19.1%. These antibodies were termed collectively as anti-D'E polypeptide in this paper and shown to have high specificity for the diagnosis of MCTD (P < 0.001).

Abstract
Schizencephaly is a neuronal migration malformation characterized by a cleft traversing the cerebral hemisphere. The cleft is lined by heterotopic gray matter, and the lips of the cleft may be fused or separated. Often associated with anomalies of the septum pellucidum or corpus callosum, and polymicrogyria, schizencephaly has characteristic CT findings. Of 17 patients with this lesion detected by CT 2 had bilateral schizencephaly.

Abstract
To test the hypothesis that rheumatoid arthritis in patients in China is milder in severity than that in patients in a western country, a comparison was made of 2 series of consecutive outpatients with definite or classic rheumatoid arthritis who were attending referral centers in Melbourne, Australia and Shanghai, China. This paper reports the findings on radiographs of the wrists and hands. Making allowances for age and duration of disease, changes were more frequent and severe in the Australian patient series, particularly at the metacarpophalangeal joints.

Abstract
A comparison was made of two series of consecutive outpatients with a presumptive diagnosis of rheumatoid arthritis (RA) attending referral centres in Melbourne and Shanghai. No significant differences were observed in disease onset, course, presence of antinuclear antibodies (ANA), or seropositivity. In the Australian series there was a higher frequency of nodules, Raynaud's phenomenon, carpal tunnel syndrome, and 'classical' in comparison with 'definite' disease, and a lower frequency of lymphadenopathy and hepatomegaly. Joint tenderness and soft tissue swelling tended to be more marked in the Chinese series, while deformity and limited range of movement were less severe. Drug therapy was similar overall but influenced by drug availability. Peptic ulceration was recorded in 28% of the Australian series but in only 6% of the Chinese; although 25% of the Chinese were receiving antacids and 6% antiulcerants. X-rays of hands and feet showed more severe disease in the Australian series. The older age group and longer duration of the disease in the Australian patients, who had more chronic and less active disease, may have influenced some of these results.
