ObjectiveTo investigate the clinical efficacy of pricking-medicinal cupping bloodletting therapy for knee osteoarthritis.MethodSixty patients with knee osteoarthritis were randomly allocated to pricking-cupping bloodletting (treatment) and conventional treatment (control) groups, 30 cases each. In the treatment group, specific points around the knee were pricked with bloodletting needles and blood was removed by cupping with decoction. In the control group, the same points were given acupuncture and the affected part was given microwave treatment. The WOMAC score was recorded in the two groups of patients before treatment and after the end of treatment course. The therapeutic effect was evaluated by comparing the pre-and post-treatment scores between the two groups.ResultThere was a statistically significant pre-/post-treatment difference in the WOMAC total score in the two groups (P<0.01). The range of decrease in the WOMAC total score was significantly larger in the treatment group than in the control group. There was a statistically significant post-treatment difference in the WOMAC total score between the two groups (P<0.01). The WOMAC item scores decreased in varying degrees in both groups after treatment (P<0.01). The total efficacy rate was statistically higher in the treatment group than in the control group; there was a statistically significantdifference (P<0.05). The clinical therapeutic effect was statistically better in the treatment group than in the control group.Conclusion Pricking-medicinal cupping bloodletting is statistically better than conventional treatment in treating knee osteoarthritis. It can effectively relieve the pain and stiffness and improve knee function and the quality of life in the patients.

Objective:To investigate the clinical characteristics and prognosis of the patients with nocardiosis.Methods:From January 2013 to July 2019, 44 patients with nocardiosis in Department of Infectious Diseases, Huashan Hospital, Fudan University in Shanghai were enrolled, and their clinical data were retrospectively analyzed, including baseline characteristics, clinical manifestations, underlying diseases history of glucocorticoid therapy, laboratory data (blood routine examination, procalcitonin, C-reactive protein, lymphocytes subsets, etc.), imaging changes, bacterial strain identification, treatment regimens and outcomes. According to the locations of infection, patients were divided into pulmonary nocardiosis, extrapulmonary single-organ nocardiosis and disseminated nocardiosis. The Mann-Whitney U test was used for comparison between two groups, and the Kruskal-Wallis H test was used for comparison among multiple groups. Results:Among the 44 cases of nocardiosis, 14 cases were pulmonary nocardiosis, 17 cases were extrapulmonary single-organ nocardiosis (including nine cases with central nervous system infection, six cases with skin and soft tissue infection, one case with abdominal abscess and one case with urinary tract infection) and 13 cases were disseminated nocardiosis (including four cases with bloodstream infection, six cases with central nervous system and lung or skin and soft tissue infection, three cases of lung and skin and soft tissue infection). Thirty-four cases had underlying diseases, and 27 cases received glucocorticoid or immunosuppressant treatment. The main symptom of 11 patients in pulmonary nocardiosis group was productive cough, while that of the patients in other two groups was fever. Nocardia species were mainly Nocardia brasiliensis, Nocardia nova and Nocardia farcinicaia. The white blood cell counts and neutrophils proportion were normal or slightly increased in 42 cases, and the platelets were normal or slightly decreased in 41 cases. Erythrocyte sedimentation rate increased in 19 cases, procalcitonin increased in 21 cases, C-reactive protein increased in 34 cases, and ferritin increased in 18 cases. A total of 34 patients were tested for lymphocyte subsets, of which 15 had CD4 + T lymphocytes decreased, 14 had CD8 + T lymphocytes increased, seven had B lymphocytes increased, seven had B lymphocytes decreased, and eight had natural killer cells decreased. The hemoglobin of patients with pulmonary nocardiosis was higher than that of patients with extrapulmonary infection, and the difference was statistically significant ( U=0.095, P=0.025). The imaging manifestations were mainly abscess and inflammatory exudation. Forty cases were cured or improved, one case was still on treatment, and three cases died. Conclusions:The clinical manifestations of nocardiosis involving various organs are non-specific. Standardized treatment could reduce the mortality of nocardiosis.

Objective:To investigate the clinical characteristics and prognosis of cytomegalovirus (CMV) reactivation in patients with liver failure.Methods:A total of 75 patients diagnosed with liver failure and tested for serum CMV DNA between January 2016 and June 2019 in Huashan Hospital, Fudan University were retrospectively analyzed. According to the CMV DNA test results, the patients were divided into CMV DNA positive group and CMV DNA negative group. The classification of liver failure, the use of glucocorticoids, the proportions of T lymphocyte subsets of the two groups were compared and the prognosis was evaluated. Mann-Whitney U test and chi-square test were used to analyze the data. Results:Of the 75 patients with liver failure, 17 were CMV DNA positive and 58 were CMV DNA negative. Among the 17 CMV DNA positive patients, nine were acute (subacute) liver failure, and 13 were treated with glucocorticoids, which were all significantly higher than those in the CMV negative group (20.7%(12/58) and 20.7%(12/58), respectively). The differences were both statistically significant ( χ2=6.70 and 18.40, respectively, both P<0.05). The proportions of CD3 + T lymphocytes and CD8 + T lymphocytes in the CMV DNA positive group were both higher than those in the CMV DNA negative group, and the proportions of CD4 + T lymphocytes, the ratio of CD4 + /CD8 + T lymphocytes and the proportion of B lymphocytes were all lower than those in the CMV DNA negative group. The differences were all statistically significant ( U=274.50, 165.50, 273.00, 185.00 and 189.00, respectively, all P<0.05). Acute (subacute) liver failure (odds ratio ( OR)=4.3, 95% confidence interval ( CI) 1.3-12.6) and glucocorticoid use ( OR=12.5, 95% CI 3.4-38.3) were risk factors for CMV reactivation in patients with liver failure. The disease improvement rate in the CMV DNA negative group was 56.9% (33/58), and five out of 17 patients improved in the CMV DNA positive group, with a statistically significant difference ( χ2=1.99, P=0.04). Conclusions:The use of glucocorticoids increases the risk of CMV reactivation in patients with liver failure, and CMV reactivation in patients with liver failure presents immune disorders which seriously affect their prognosis. Therefore, it is important to pay attention to CMV DNA monitoring in patients with liver failure using glucocorticoids.

This study investigated the changes of CD4(+) CD25(+) regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better; and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4(+)CD25(+) Tregs among CD4(+) T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and 1 week after TACE (P<0.01), whereas, that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4(+)CD25(+) Tregs in peripheral blood. TACE did not significantly affect the level of CD4(+) CD25(+) Tregs within short time (such as 1 week). The proportion of CD4(+)CD25(+) Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.
