RESUMEN
ObjectiveIn the treatment of acute gouty arthritis （AGA）， western medicine is mostly used for anti-inflammatory and analgesic purposes to control the blood uric acid level， but some patients are still at risk of poor control and recurrent attacks. Chinese medicinal prescriptions， potent in resisting inflammation and relieving pain， are able to stabilize the blood uric acid level， reduce acute attacks， and improve the clinical efficacy of western medicine. However， there is a lack of evidence to support their use as evidence-based medicine. This study employed network Meta-analysis （NMA） to evaluate the efficacy and safety of common Chinese medicinal prescriptions in the treatment of AGA， aiming to provide evidence-based medical evidence for the clinical use of Chinese medicinal prescriptions in the treatment of AGA. MethodChinese and English databases were searched for prospective cohort studies and randomized controlled trials （RCTs） on Chinese medicinal prescriptions against AGA from database inception to December 1， 2022. Stata software and Review Manager were used for statistical analysis. ResultForty-four papers with 3 564 cases involved were included in the current NMA. In terms of reducing blood uric acid， the cumulative probability results showed that Mahuang Lianyao Chixiaodou Tang showed optimal efficacy （87.60%）. In terms of relieving joint pain， Danggui Niantongtang and Guizhi Shaoyao Zhimutang showed optimal efficacy （92.00% and 82.30%）. In terms of improving erythrocyte sedimentation rate （ESR）， Simiaowan was superior to other prescriptions （87.00%）. In terms of reducing C-reactive protein （CRP）， Simiaowan and Baihutang modified with Guizhitang showed superior efficacy （76.00% and 66.10%）. In terms of safety， except for the basic treatment group， Mahuang Lianyao Chixiaodou Tang had the lowest probability of adverse events， and Danggui Niantongtang had the highest probability of adverse reactions during treatment. According to the results of cluster analysis， Mahuang Lianyao Chixiaodou Tang and Simiaowan are effective and safe. ConclusionAccording to the results of NMA， Chinese medicinal prescriptions can assist in the treatment of AGA and improve the effectiveness of western medicine. For patients with AGA， clinicians can choose Mahuang Lianyao Chixiaodou Tang or Simiaowan as an auxiliary drug for routine western medicine treatment.

Objective:To analyze the laboratory tests in newly hospitalized patients with COVID-19 and their predictive values for the severity of the disease.Methods:83 patients, including 54 males and 29 females, with median interquartile range of 63(53-70)years diagnosed with covid-19 who were managed by Fujian medical team from January 27, 2020 to February 20, 2020 in Wuhan JinYinTan Hospital were studied retrospectively. According to the severity of the disease, they were divided into common, severe and critical groups. White blood cell (WBC), lymphocyte (LYM), loctate dehydrogenase (LDH), interleukin-6 (IL-6), procalcitonin (PCT), serum ferritin (SF), erythrocyte sedimentation rate (ESR), hypersensitive C-reactive protein (hs-CRP) and D-Dimer (D-D) on admission were analyzed retrospectively. And the predictive value of each indicator for critical group was analyzed by Logistic regression.Results:On admission, in common, severe and critical groups, WBC (×10 9/L) values were 7.10±3.88, 7.73±3.77 and 9.07±5.61, respectively ( F = 1.315, P=0.274); IL-6 (μg/L) values were 11.76(9.42-15.18), 11.93(10.15-15.63) and 11.24(8.06-13.75), respectively( Z=0.591, P=0.744);D-D (mg/L) values were 0.70(0.48-1.12), 1.67(1.07-7.14) and 1.96(0.71-8.18), respectively( Z=3.363, P=0.186).There were no significant differences among three groups. On admission, in common, severe and critical groups, LYM(×10 9/L) values were 1.10±0.33, 0.80±0.35 and 0.66±0.32, respectively( F=11.415, P<0.001); SF(μg/L) values were 470.83±283.43, 835.66±819.43, and 1341.15±949.54, respectively ( F=7.98, P=0.001); ESR(mm/h) values were 30.76±15.70, 42.55±22.51 and 51.04±25.09, respectively( F=5.181, P=0.008); LDH(U/L) values were 314.71±105.46, 325.69±109.85 and 444.03±181.07, respectively( F=7.17, P=0.001); hs-CRP(μg/L)values were 16(7.20-19.90), 31.00(20.00-87.60) and 80.50(33.70-113.00), respectively( Z=12.185, P=0.002);PCT(μg/L) values were 0.025(0.02-0.05), 0.05(0.02-0.13) and 0.09(0.05-0.39), respectively( Z=9.694, P=0.008). There were significant differences among three groups. Pairwise comparison showed that the LYM value in common group was higher than those in severe and critical groups, and the hs-CRP values in severe and critical groups were higher than that in common group,while SF, ESR, LDH and PCT values in critical group were all higher than those in severe and common groups( P<0.05). Conclusions:On admission, WBC, LYM, ESR and LDH are helpful to predict the severity of COVID-19. Although the level of IL-6 is increased, it may not be meaningful to judge the severity of COVID-19.

OBJECTIVE:To establish the method for simultaneous determination of 9 common inorganic anions in Huanglian shangqing tablet. METHODS:The accelerated solvent extraction-ion chromatography was adopted. Inorganic anions were deter-mined by Ion Pac AS11-HC anion exchange column,protected by Ion Pac AG11-HC column and eluted by hydroxide potassium so-lution(gradient elution)at the flow rate of 1.2 mL/min. The column temperature was set at 30 ℃,elution time was 18 min,and sample volume was 25 mL. RESULTS:The linear ranges of fluorinion,formate ion,nitrite ion,bromide ion,nitrate ion,sulfate ion,oxalate ion and phosphate ion were 0.1-5 mg/L(r=0.9990-0.9999). The limits of quantitation were 0.020,0.078,0.030, 0.058,0.052,0.068,0.084,0.064,0.074 mg/L,and the limits of detection were 0.005,0.024,0.008,0.017,0.015,0.022, 0.026,0.020,0.021 mg/L,respectively. RSDs of precision,stability and repeatability were all lower than 4.0%;recoveries were 80.00%-125.08%(RSD ranged 0.97%-2.47%). CONCLUSIONS:The method is simple,precise,stable and repeatable,and can be used for 9 common inorganic anions in Huanglian shangqing tablet.
RESUMEN
BACKGROUND: To prepare a novel biological material that can be implanted into the lesion of bone tuberculosis, keep sustained release of anti-tuberculosis drugs around bone tuberculosis tissues for a long time, and enhance the effect on bone repair has become a hot spot for clinical studies on bone tuberculosis.OBJECTIVE: To prepare the adipose-derived mesenchymal stem cells (ADMSCs)/sustained-release rifampin-loaded microsphere complex, and to preliminarily study its effects in a rabbit model of spinal tuberculosis.METHODS: Rifampin-chitosan-calcium alginate sustained-release microspheres were synthesized, and co-cultured with ADMSCs to prepare an anti-tuberculosis composite for bone tissue engineering. Forty New Zealand rabbits were used to make lumbar L6 tuberculosis models. Thereafter, rat models were randomly divided into four groups and given rifampin by gavage in rifampin group, ADMSCs by paravertebral injection+rifampin by gavage in stem cell group, rifampin by gavage+implantation of the anti-tuberculosis composite material in experimental group, and no treatment in control group.The duration time of rifampin administration was 8 weeks. The anti-tuberculosis effect of the composite material was evaluated by X-ray and CT scanning observation.RESULTS AND CONCLUSION: In the control group, obvious damage to lumbar vertebrae L5 and L6 was apparent; inflammatory granulation tissues formed; and the intervertebral space was narrowed. In addition, two rabbits in the control group showed obvious kyphotic deformity and five showed pasoas major swelling with low-density dark region in the psoas muscle. In the rifampin group, there were five rabbits with moderate damage of the lumbar vertebrae L5 and L6,and two rabbits with pasoas major swelling. In the stem cell group, there were two rabbits with moderate damage of the lumbar vertebrae L5 and L6, three rabbits with mild damage of the upper part of the lumbar vertebra L6, and three rabbits with pasoas major swelling. In the experimental group, only four rabbits suffered from mild damage of the upper part of the lumbar vertebra L6 but with no changes in the intervertebral space between the L5 and L6, and without pasoas major swelling. These results indicate that the composite material of ADMSCs combined with sustained-release rifampin-loaded microspheres can inhibit mycobacterial growth effectively, and reduce vertebral bone destruction,thereby giving some therapeutic actions for the animal models with spinal tuberculosis.
