OBJECTIVETo explore clinical outcomes of posterior malleolar fractures with medial-extension type through posterioromedial and posteriorlateral incision.
METHODSFrom January 2008 to January 2011,25 patients with posterior malleolar fractures with medial-extension type were treated by hollow lag screw. Among them, 15 patients were treated through posteromedial incision,including 9 males and 6 females,aged from 21 to 67 years old with an average of 48.1 +/- 1.3; there were 5 cases with type A, 6 cases with type B and 4 cases with type C,according to Denis-Weber classification. Ten patients were treated by through posterior-lateral incision,including 6 males and 4 females, aged from 23 to 64 years old with an average of 46.9 +/- 1.5; there were 3 cases with type A, 5 cases with type B and 2 cases with type C,according to Denis-Weber classification. Operation time, blood loss, length of incision, times of X-ray exposure and complications of two groups were recorded and compared, Baird-Jackson effective evaluation were applied for evaluate clinical outcomes.
RESULTSAll patients were followed up from 12 to 49 months with an average of 20.6 months. There were significant differences in operation time, blood loss, times of X-ray exposure and complications between two group (P < 0.05). While there was no obvious meaning in clinical outcomes between two groups (P > 0.05).
CONCLUSIONTreating posterior malleolar fractures with medial-extension type through posteromedial approach can expose and fix fracture under direct vision, has advantages of shorter operation time, less X-ray exposure and blood loss, is a good choice of surgical approach.

Abstract: Objective To analyze the changes of cytokine levels in patients with sensitive pulmonary tuberculosis and drug-resistant pulmonary tuberculosis before and after anti-tuberculosis treatment. Methods The clinical data of 213 pulmonary tuberculosis patients admitted to the Eighth Affiliated Hospital of Xinjiang Medical University from August 2019 to October 2020 were collected, and divided into a sensitive pulmonary tuberculosis group and a drug-resistant pulmonary tuberculosis group, of which 141 were in the sensitive group and 72 in the drug-resistant group , and the pro-inflammatory factors tumor necrosis factor-α (TNF-α), IL-6, IL-17, interferon-γ (IFN-γ) and anti-inflammatory factors IL-10 and IL-4 in plasma before treatment, 3 months and 6 months after treatment were compared. Results Compared with the healthy group, the levels of plasma IL-6 in the sensitive group and the resistant group were significantly increased, difference was statistically significant (P<0.01). The plasma levels of IFN-γ and IL-17 in the sensitive group were increased, and the difference was statistically significant (P<0.05). Compared with before treatment, the levels of IL-6 and IL-4 in the plasma of the sensitive group after 6 months of treatment were lower than those after 3 months of treatment, and the difference was statistically significant (P<0.05), and IFN-γ was significantly decreased (P<0.001). After 6 months of treatment, the IL-10 content was lower than that before treatment, and the difference was statistically significant (P<0.05), and the IFN-γ decreased significantly (P<0.000 1). The levels of IFN-γ at 3 months were higher than those in the resistant group, and the difference was statistically significant (P<0.01). After 6 months of treatment, there was no significant difference in the content of IFN-γ between the sensitive group and the resistant group. The effective rate of CT absorption was 70% in the sensitive group and only 43.33% in the resistant group at 3 months of treatment, and there was no significant difference in the effective rate between the two groups after 6 months of treatment. Conclusions Detection of pro-inflammatory cytokines and anti-inflammatory cytokines in plasma can provide reference for host-directed therapy of pulmonary tuberculosis. Understanding this important feature of cytokines on pathogen-host interactions can provide new insights into the study of virulence mechanisms and may provide new approaches for immune intervention in pulmonary tuberculosis.

Objective To explore the therapeutic mechanism of narrow-band ultraviolet B (NB-UVB)in psoriasis. Methods Forty-two patients with psoriasis vulgaris and 20 healthy controls were enrolled into this study. All the patients received 20 sessions of NB-UVB radiation. Psoriasis area severity index (PASI)was used to evaluate the severity of psoriasis. Blood samples were collected from all the patients before and 15 cured patients after the treatment as well as from 20 healthy controls, and skin samples from 10 patients before and after the treatment as well as from 10 healthy controls. Enzyme-linked immunosorbent assay (ELISA)was performed to determine the serum levels of IL-17 and IL-22, and real-time fluorescence-based quantitative PCR to measure the mRNA expressions of IL-17 and IL-22 in skin specimens. Statistical analysis was carried out by using the two-sample t-test, paired t-test and Pearson correlation analysis. Results After 20 sessions of NB-UVB radiation, 15 out of the 42 patients were cured with a significant decrease in PASI. Compared with the healthy controls, the 15 cured patients showed a significant elevation in the levels of IL-17and IL-22 proteins(IL-17: 34.26 ± 10.05 ng/L vs. 16.34 ± 4.73 ng/L, t = 7.016, P < 0.01; IL-22: 13.72 ± 4.45 ng/L vs. 5.03 ± 1.84 ng/L, t = 8.282, P < 0.01)and mRNAs (IL-17: 13.43 ± 2.12 vs. 5.26 ± 0.87, t = 6.312, P < 0.01; IL-22:16.53 ± 2.65 vs. 7.72 ± 2.13, t = 6.823, P < 0.01)before the treatment. The PASI score was positively correlated with the levels of IL-17 and IL-22 proteins in sera (r = 0.76, 0.70, respectively, both P < 0.05)and their mRNAs in skin lesions (r = 0.65, 0.68, respectively, both P < 0.05)in these patients. The serum levels and mRNA expressions of IL-17 and IL-22 all significantly reduced in the cured patients after the treatment compared with those before the treatment(all P < 0.05). Conclusion NB-UVB may treat psoriasis by downregulating the levels of IL-17 and IL-22 in peripheral blood and skin lesions in patients with psoriasis.
