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 evaluate the feasibility and efficiency of laparoscopic-guided radiofrequency ablation on advanced prostate cancer.Methods From March 2003 to December 2008,a total of 6 previous prostate cancer patients who had been diagnosed with pathological results were treated by laparoscopic-guided radiofrequency ablation.All patients underwent pre-and post-operative IPSS,serum PSA,MRI and normal blood biochemistry examination.The treatment outcome,surgery-related complications were also recorded.Results All operations were successfully completed,no serious intra-and post-operative complications happened.Although there was no significant difference of IPSS between pre-operative [ ( 19.05 + 4.28 ) scores ] and 1 month after operation [ ( 19.87 + 5.72) scores ],but there were significantly decreased in 3 months [ (9.45 ± 2.03 ) scores ] and 6 months [ (6.18 + 1.79) scores ] after operation (P ＜0.05).Also being followed up to 6 months after operation,the serum PSA was significantly decreased compared with the pre-operative value [from(24.80 ± 14.56) μ g/L reduced to( 13.79 ± 7.76) μ g/L](P＜0.05).Conclusion Laparoscopic-guided radiofrequency ablation on advanced prostate cancer is safe and feasible,and can be used as an effective treatment in selective cases.

Introduction: Bekam, an Islamic variant of cupping, is an ancient form of traditional medicine still practised today in Malaysia. There are published findings indicating that cupping benefits patients with low back pain, other musculoskeletal pain and even pain from cancer, herpes zoster and trigeminal neuralgia when pain is measured on an analogue scale. We proposed to investigate whether in addition to pain improvement on an analogue scale we could show if pain relief might be demonstrated in terms of reduction of analgesic use. Methods: We carried out a retrospective cross sectional study on subjects who had been for outpatient clinic treatment with chronic pain of at least one month and who completed at least two bekam therapy sessions. In addition to documenting a pain score before and after therapy we documented their analgesic consumption. Results: A total of 77 respondents, with overlapping symptoms of headache, backache and joint pains were included. The mean pain score before bekam therapy was 6.74±1.78, and was 2.66±1.64 after two sessions of therapy. Twenty eight respondents completed six sessions of bekam therapy and had a mean pain score of 2.25±1.32 after. Thirty-four patients consumed analgesic medication before starting bekam therapy and only twelve did so after. The consumption of analgesics was significantly lower after bekam therapy. Conclusions: Bekam therapy appears to help patients experience less pain and reduce the amount of analgesic medication they consume. Nevertheless only a randomised prospective study will eliminate the biases a retrospective study is encumbered with and we believe would be worth doing.

AIMTo develop a rapid and sensitive LC/MS/MS method for the analysis of levodropropizine in plasma and study the pharmacokinetics of levodropropizine in healthy Chinese volunteers.

METHODSLevodropropizine and zolmitriptan (internal standard, IS) were extracted from plasma samples and chromatographed on a C18 column and detected using a tandem mass spectrometer with a TurboIon Spray ionization interface. Quantitation was performed using multiple reaction monitoring (MRM) of the transitions of the m/z 237 --> m/z 120 for levodropropizine and m/z 288 --> m/z 58 for the IS.

RESULTSThe limit of quantification of the method for levodropropizine was 0.25 microg x L(-1). The assay was linear over the concentration range from 0.25 to 500.0 microg x L(-1) and intra- and inter-day precision over this range were < 11.4% with good accuracy.

CONCLUSIONThe method is shown to be accurate, and suitable for clinical pharmacokinetic study of levodropropizine.

OBJECTIVETo determine serum carnitine levels in patients with liver diseases and to investigate their significance.

METHODS25 patients with acute viral hepatitis, 34 with chronic viral hepatitis, 22 with post hepatitis cirrhosis with normal renal function, 9 with post hepatitis cirrhosis but with renal disfunction, and 40 healthy subjects (serving as controls) were enrolled in this study. An enzymatic cycling method was used to determine the serum free carnitine levels.

RESULTSThe serum free carnitine level was (48.3+/-10.2)micromol/L in the healthy control group. It was (35.2+/-13.2)micromol/L in the acute viral hepatitis group, (36.5+/-9.9)micromol/L in the chronic viral hepatitis group, (45.0+/-11.0)micromol/L in the post hepatitis cirrhosis with normal renal function group, and (83.6+/-50.4)micromol/L in the post hepatitis cirrhosis with renal dysfunction group. Serum free carnitine levels in the acute viral hepatitis and chronic viral hepatitis groups were significantly lower than those in the healthy controls. There were no significant differences in serum free carnitine levels of the post hepatitis cirrhosis group and the normal control group.

CONCLUSIONSPatients with liver diseases can have carnitine metabolism errors. One of the secondary carnitine lack causes is liver disease.
