One hundred cases of vocal nodules and vocal polypswere treated with the Powder with an effective rate of36%.mitigated rate of 27%.the total effective ratebeing 63%.The effective rate was related to the TCMtyping of syndromes,types,sizes and colors of vocalpolyps and has nothing to do with the locations of thelesion.After 3 months of treatment,the abnormalhemorhe ologicaal changes in vocal noddules an sessilevocal polyps were markedly improved.

Objective To explore the effects of Chinese herbal compound Tangbikang on the expressions of p38 MAPK of sciatic nerve and plasma TNF-α in diabetic rats. Methods Ten of the sixty male SD rats were selected randomly as normal group, and the rest were fed with high-fat diet and low-dosage STZ was used to induce type Ⅱdiabetic rat models. Model rats were randomly divided into model group, mecobalamine group and Tangbikang low-, medium-, and high-dosage groups, 10 rats in each group. Each medication group was intervened with relevant medicine. Rat unilaterals sciatic nerves were taken after 16 weeks. The content of TNF-α in plasma was determined by radioimmunoassay. Western blot method was used to detect the expressions of p38 and p-p38 MAPK protein of sciatic nerve. Results Compared with normal group, the expressions of p38 and p-p38 protein and content of TNF-αin model group significantly increase (P<0.05, P<0.01). Compared with the model group, the expressions of p-p38 protein and the content of TNF-α significantly decreased after medicine intervention in different doses Tangbikang groups and mecobalamin group (P<0.05, P<0.01). The expression of p38 protein in Tangbikang high-dose group significantly decreased (P<0.05), with statistical significance (P<0.05). Conclusion Tangbikang can reduce the expression of p38 and p-p38 MAPK protein of the rat sciatic nerve, and reduce the content of TNF-α protein in rat plasma, which may be one of the effective targets of neuroprotection and abirritation of diabetic peripheral neuropathy.

ObjectiveTo observe the effect of 99Tc-methylene diphosphate (99Tc-MDP, Yunke) combined with rehabilitation on ankylosing spondylitis (AS).Methods118 AS patients were randomly divided into the treatment group (n=58) and control group (n=60). The treatment group was treated with meloxicam, sulfasalazine and vein injecting Yunke combined rehabilitation. The control group was treated only with meloxicam and sulfasalazine. The changes of both clinical and experimental indexes of two groups before and after treatment were analyzed.ResultsAfter two therapeutic courses, a much better result was obtained in the treatment group compared with the control group at the respects of releasing arthralgia, shortening morning stiffness, improving range of spinal motion, and decreasing the levels of ESR, CRP, PLT and IgM, ect (P<0.05～0.01) without obvious side effects.ConclusionThe effect of Yunke combined with rehabilitation on AS is evident.

Objective:To investigate the variation of reference ranges of hemodynamic parameters in normal pregnancy and their relation to maternal basic characteristics.Methods:A total of 598 healthy pregnant women who underwent regular prenatal examination at the Third Affiliated Hospital of Guangzhou Medical University from January to December 2023 were prospectively enrolled, and noninvasive hemodynamic monitors were used to detect changes in hemodynamic parameters of the pregnant women with the week of gestation, including cardiac output (CO), stroke volume (SV), thoracic fluid content (TFC), systemic vascular resistance (SVR), mean arterial pressure (MAP), and heart rate (HR). Relationships between hemodynamic parameters and maternal basic characteristics, including age, height, and weight, were analyzed using restricted cubic spline.Results:(1) CO ( r=0.155, P<0.001), TFC ( r=0.338, P<0.001), MAP ( r=0.204, P<0.001), and HR ( r=0.352, P<0.001) were positively correlated with the week of gestation, and SV was negatively correlated with the week of gestation ( r=-0.158, P<0.001). There was no significant correlation between SVR and gestational age ( r=-0.051, P=0.258). (2) CO exhibited a positive correlation with maternal height and weight (all P<0.001). The taller and heavier of pregnant women, the higher their CO. A linear relationship was observed between maternal weight and SV, MAP and HR (all P<0.01). As maternal weight increased, SV, MAP and HR showed an upward trend. Furthermore, there was an inverse association between maternal age and SVR ( P<0.001). (3) There was a significant nonlinear association observed between TFC and body mass index during pregnancy ( P<0.05). Additionally, a nonlinear relationship was found between SVR and MAP in relation to maternal age (all P<0.05). Notably, when the age exceeded 31 years old, there was an evident upward trend observed in both SVR and MAP. Conclusions:The hemodynamic parameters of normal pregnant women are influenced by their height, body weight, and age. It is advisable to maintain a reasonable weight during pregnancy and give birth at an appropriate age.

OBJECTIVE To predict the in vivo bioequivalence of lenvatinib mesilate capsules and reference preparation by using the parallel artificial membrane permeability analysis. METHODS Based on the biopharmaceutics classification system classification of lenvatinib mesilate and the parallel artificial membrane permeation model, the in vitro dissolution permeation rate test model of lenvatinib mesilate capsules was established, through real-time monitoring of the dissolution and penetration of lenvartinib mesylate capsules and reference preparations in fasting gastric juice, intestinal fluid and postprandial intestinal fluid, the flux and total penetration of drugs through the membrane were calculated. RESULTS In fasting state and fed state, the 90% confidence interval of geometric mean ratio of two key quality parameters (permeation flux and permeation amount) of the preparation A all were in the range of 80.00%−125.00%, the preparation B did not fall into this interval. CONCLUSION This research method can predict the bioequivalence of renvartinib mesylate capsule and reference preparation, and has a certain correlation in vivo and in vitro.
