Background Knee osteoarthritis (KOA) is a common clinical condition with a decades-long course. Long-term and personalised health management in community hospitals is the best way to prevent and treat KOA, and non-surgical treatment is an effective way to slow joint degeneration and postpone joint replacement surgery. Objective To understand the population characteristics, clinical staging and treatment modality characteristics of the population attending community hospitals for knee osteoarthritis, in order to provide a basis for optimising the treatment protocol for knee osteoarthritis at the grassroots level. Method All streets in the urban area of Beijing were randomly selected for the study using the whole cluster sampling method, and Hepingli Street in Dongcheng District, Beijing was censored for all patients who attended all community hospitals (7) belonging to the street from January to June 2022, and general information, medical history, personal history, clinical staging, K-L grading and treatment modalities were collected. Results A total of 3 615 KOA patients were included in this study, including 1 327 males (36.71%) and 2 288 females (63.29%), aged (71.8±13.3) years. There were 867 cases (23.98%) in the onset period, 2009 cases (55.57%) in the remission period and 739 cases (20.45%) in the rehabilitation period. Gender and age of patients with different clinical stages were not correlated with clinical stages (P>0.05), while BMI (K=0.235) and KL grading (K=0.406) were correlated with clinical stages (P

Objective: To observe the effect of Huogu II formula compatible with different channel ushering drugs on the homing of bone marrow stem cells of osteonecrosis of the femoral head (ONFH) induced by liquid nitrogen freezing in rabbits and discuss the mechanism for preventing and treating ONFH., Method: The ONFH model was established by liquid nitrogen freezing of 84 rabbits. They were randomly assigned to the model group and the Huogu II formula group and groups of Huogu II formula combining with Achyranthis Bidentatae Radix, Asari Radix et Rhizoma, Angelicae Pubescentis Radix, Platycodonis Radix. The remaining 14 rabbits were sham-operated. During the course of ONFH modeling, all of the rabbits were subcutaneously injected with recombinant human granulocyte colony-stimulating factor (rhG-CSF)(30 microg x kg(-1) x d(-1), for consecutively 7 days). Meanwhile, normal saline and decoction of the formulae were orally administrated respectively. WBC was counted in peripheral blood before and after the injection of rhG-CSF. HE stainings at the 2nd and the 4th weeks after the modeling were adopted to observe histopathological changes, vascular morphology was observed by ink perfusion, BrdU and SDF-1 were determined by immunohistochemical assay in femoral heads of the left hind leg., Result: Compared with the sham-operated group, the Huogu II formula group showed decrease in the ratio of empty lacuna and increase in vessel area, number of BrdU positive cells and SDF-1 level. In comparison with the model group, the Achyranthis Bidentatae Radix group displayed decreasing empty lacuna ratio and increasing vessel area at the 4th week and increasing SDF-1 at the 2nd week; the Platycodonis Radix group revealed a notably increasing empty lacuna ratio and a sharp decrease in the number of BrdU positive cells at 4th week; Asari Radix et Rhizoma and Angelicae Dubescentis Radix groups showed no remarkable change., Conclusion: Huogu II formula can promote the directional homing of bone marrow stem cell to the necrosis area. Channel ushering drug achyranthes can further boost above effects of Huogu II formula.

Objective: To learn the effects of coptis in treating neonatal jaundice and to find the index that guides the clinical administration of the medicine., Method: Clinical data of 412 cases of neonatal jaundice were studied retrospectively, and univariate and multivariate analysis were made to the factors affecting the incidence according to the Cox model which led to the establishment of the predictive equation. According to the regression coefficients, the relative risk, wald value, the coptis effects were evaluated on the incidence of neonatal jaundice., Result: Single-factor Cox model analysis shows that there are five main factors affecting the incidence of neonatal jaundice, Multivariate Cox model analysis indicates that the five main factors are also independent factors that affect the incidence, the roles of which, ranking from minor to major are, in turn, age, applied coptis, ethnic, G6PD deficiency and cesarean section. Among them, the regression coefficient is -0.259, relative risk 0.772, wald value 6.832. It sugguests that coptis may reduce the incidence of neonatal jaundice, and that it is a protective factor. The prediction equation, by regression coefficients, which has been used to establish the incidence of neonatal jaundice, is as following: h(t, x) = h0 (t) exp (- 0.022 x2 - 0.494x3 + 0.344x8 + 0.226x9 - 0.259x10)., Conclusion: Coptis is one of the important factors that affect the occurrence of neonatal jaundice, and it has a protective effect in preventing neonatal jaundice from occurrence.
