Abstract
BACKGROUND Osteonecrosis of the femoral head (ONFH) is a prevalent orthopedic issue, leading to the collapse and fragmentation of the femoral head in its advanced stages, which can severely impair patients' quality of life. Total hip arthroplasty (THA) is a clinical intervention frequently used to alleviate ONFH symptoms and reinstate hip functionality. The conventional surgical technique is invasive and comes with an extended recuperation period, posing significant challenges for patients. With the progression of medical technology, the use of the mini-incision technique in minimally invasive THA (MITHA) has become more prevalent. However, comparative studies examining the effectiveness of these two surgical procedures in treating ONFH remain scarce. Furthermore, understanding patients' psychological well-being is crucial given its profound influence on postoperative recuperation. AIM To evaluate the impact of mini-incision MITHA on ONFH treatment and to identify the risk factors associated with postoperative anxiety and depression. METHODS A retrospective study was conducted on 125 patients treated for ONFH at Xi'an Hong Hui Hospital between February 2020 and January 2022, with the term "consecutive" indicating that these patients were treated in an unbroken sequence without any selection. Among these, 60 patients (control group) underwent traditional THA, while 65 patients (observation group) were treated with mini-incision MITHA. Variations in the visual analog scale (VAS) score and the Harris hip score were monitored. Additionally, shifts in pre- and posttreatment Hamilton anxiety (HAMA) and Hamilton depression (HAMD) scale scores were recorded. Patients with both postoperative HAMA and HAMD scores of ≥ 8 were identified as those experiencing negative emotions. Logistic regression was utilized to analyze the determinants influencing these negative emotional outcomes. Comparative analyses of surgical and postoperative metrics between the two groups were also conducted. RESULTS Posttreatment results indicated a significantly higher VAS score in the control group than in the observation group, while the Harris score was considerably lower (P < 0.0001). The observation group benefited from a notably shorter operation duration, reduced blood loss, diminished incision size, and a decreased postoperative drainage time (P < 0.0001), accompanied by a reduced hospital stay and lower treatment costs (P < 0.0001). The control group had elevated posttreatment HAMA and HAMD scores in comparison to the observation group (P < 0.0001). Multivariate logistic regression revealed that being female [odds ratio (OR): 4.394, 95%CI: 1.689-11.433, P = 0.002], having a higher postoperative VAS score (OR: 5.533, 95%CI: 2.210-13.848, P < 0.0001), and having higher treatment costs (OR: 7.306, 95%CI: 2.801-19.057, P < 0.0001) were significant independent determinants influencing postoperative mood disturbances. CONCLUSION Compared to conventional THA, mini-incision MITHA offers advantages such as reduced operation time, minimal bleeding, and a shorter incision in ONFH patients. Moreover, factors such as sex, postoperative pain (reflected in the VAS score), and treatment costs significantly impact postoperative anxiety and depression.

Abstract
Objective: To investigate the association of circulating sPD-1 level and PD-1 gene polymorphisms with HBV infection and HBV infection-associated hepatocellular carcinoma. Methods: A case-control study was conducted. A total of 237 chronic HBV infection cases and 138 HBV infection-associated hepatocellular carcinoma in the Department of Infectious Diseases of the First Hospital of Shanxi Medical University from 2018 to 2021 were selected as the case group. About 250 individuals who visited a hospital physical examination center for routine physical examination during the same period were selected as the control group. Plasma sPD-1 levels were measured by using an ELISA kit and genotyping was performed by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The association of sPD-1 levels and PD-1 polymorphisms with HBV infection as well as HBV infection-associated hepatocellular carcinoma was analyzed by using logistic regression models after adjusting for age, sex, alcohol consumption, smoking, ALT and AST levels. The sPD-1 level and PD-1 polymorphisms were independent variables, and HBV infection was the dependent variable. Results: The age of 237 chronic HBV infections, 138 HBV infection-related liver cancer case subjects and 250 control subjects in the study was (49.1±10.8), (51.9±12.7) and (50.7±11.9) years, respectively. Multivariate logistic regression model analysis showed that with a 1 pg/ml increase in sPD-1 level, the OR (95%CI) values for the risk of incident HBV infection cases and HBV hepatocellular carcinoma cases were 1.92 (1.68-2.19) and 2.02 (1.69-2.40). For rs2227981, compared with the CC genotype, the TT genotype had a lower risk of HBV infection and liver cancer associated with HBV infection, with OR (95%CI) values of 0.45 (0.22-0.91) and 0.35 (0.14-0.91). For rs2227982, compared with the CC genotype, the CT and TT genotypes also had a lower risk of HBV infection [OR (95%CI) values of 0.72 (0.53-0.97) and 0.57 (0.35-0.93)] and HBV infection-related liver cancer [OR (95%CI) values of 0.64 (0.45-0.92) and 0.52 (0.29-0.93)]. Conclusions: Plasma sPD-1 levels and PD-1 gene polymorphisms are associated with HBV infection and HBV infection-associated hepatocellular carcinoma.

Abstract
OBJECTIVE To analyze the clinical effect of decompression and bone grafting on osteonecrosis of the femoral head(ONFH) at different sites of necrotic lesions. METHODS A total of 105 patients with ARCOⅡstage ONFH admitted from January 2017 to December 2018 were retrospectively analyzed. There were 71 males and 34 females, with an average age of (55.20±10.98) years old. The mean course of all patients was(15.91±9.85) months. According to Japanese Inveatigation Committee (JIC) classification, all patients were divided into 4 types:17 cases of type A, 26 cases of type B, 33 cases of type C1 and 29 cases of type C2. All four groups were treated with decompression of the pulp core and bone grafting. Visual analogue scale(VAS) and Harris hip joint score were used before and at 3, 6, 12, and 24 months after the operation, and the collapse of the femoral head was observed by X-ray examination within 2 years. RESULTS All 105 patients were successful on operation without complications, and the mean follow-up duration was (24.45±2.75) months. Harris score showed that there was no statistical difference among four groups before surgery and 3, 6 months after surgery (P>0.05);at 12 and 24 months after surgery, there were significant differences among all groups (P<0.01). There were significant differences in intragroup Harris scores at preoperative and postoperative time points among four groups (P<0.01). VAS showed that there was no statistical difference among four groups before and 3, 6 months after surgery (P>0.05);at 12 and 24 months after surgery, there were significant differences among all groups (P<0.01). There were significant differences in VAS at preoperative and postoperative time points among four groups (P<0.01). None of the patients in four groups had femoral head collapse before and 3, 6 months after surgery. At 12 months after operation, there were 3 cases of femoral head collapse in group C and 4 cases in group C2(P>0.05);At 24 months after operation, 1 case of femoral head collapse occurred in group B, 6 cases in group C1 and 8 cases in group C2(P<0.05). CONCLUSION Core decompression and bone grafting can improve the effect of ONFH and hip preservation. The effect of hip preservation for ONFH is closely related to the location of the osteonecrosis lesion, so the influence of the location of lesion on the effect of hip preservation should be considered in clinical treatment, so as to make better preoperative hip preservation plan.

Abstract
OBJECTIVE To compare clinical effect of robot-assisted core decompression and conventional core decompression in treating ARCO Ⅰ stage necrosis of femoral head. METHODS A retrospective analysis was performed on 60(unilateral operation) patients who underwent core decompression for femoral head necrosis from February 2018 to February 2020. Among them, 30 patients(30 hips) were underwent robot-assisted core decompression (RCD group), including 19 males and 11 females, aged from 17 to 58 years old with an average of(38.50±10.61) years old;30 patients(30 hips) were underwent traditional core decompression surgery (CCD group), including 20 males and 10 females, aged from 20 to 55 years old with an average of (40.63±10.63) years old. Intraoperative fluoroscopy times, intraoperative blood loss and operation time between two groups, and Harris score, visual analogue scale (VAS) before opertaion and 24 months after operation were compared. RESULTS All patients were followed up, RCD group followed up from 21 to 26 months with an average of(23.40±1.65) months, CCD group followed up from 21 to 26 months with an average of (23.30±1.66) months, and had no difference between two groups(P>0.05). The number of intraoperative X-ray fluoroscopy, intraoperative blood loss and operative time in RCD group were (9.43±1.14) times, (153.80±22.04) ml, (33.40±1.87) min, respectively;while(19.67±1.32) times, (165.04±20.41) ml and (54.75±3.46) min in CCD group respectively;and there were statistical difference between two groups(P<0.05). In addition, there were no statistical difference between two groups in Harris score and VAS at 24 months after operation(P>0.05). CONCLUSION Compared with conventional core decompression, robot-assisted core decompression could reduce the number of intraoperative fluoroscopy, shorten operation time, and reduce risk of surgery.

Abstract
Objective: To describe the clinical characteristics of pulmonary cryptococcosis(PC)coexisting with lung cancer. Methods: We reported 3 cases of PC coexisting with lung cancer confirmed by pathology in Qingdao Municipal Hospital from January 2017 to December 2021.We reviewed the literature with"pulmonary cryptococcosis" and "lung cancer" as the keywords to search Wanfang database, China HowNet and PubMed database. Results: The patients consisted of 2 males and 1 female. Two patients were diagnosed with nodular type of PC and one with diffuse mixed type of PC. One patient had underlying cardiovascular diseases and the other two had no medical history. The clinical manifestations varied including fever, cough, sputum, and no specific symptoms. All the patients received surgery and postoperative medical therapy, and all 3 patients were pathologically confirmed with adenocarcinoma. A total of 18 cases were retrieved from related literatures. To our knowledge, one of our cases was the first one with diffuse mixed type of PC coexisting with lung cancer. Conclusions: Coexistence of pulmonary cryptococcosis and lung cancer is rare and the clinical symptoms are nonspecific. When PC coexists with lung cancer, it is extremely easy to be misdiagnosed. Therefore, PC should be considered in the differential diagnosis of pulmonary nodules and multiple imaging changes.

Abstract
OBJECTIVE This study aimed to research whether anterior tibial crest is a reliable anatomical reference for rotational alignment of tibial component in TKA. METHODS The study included 122 patients who underwent computed tomography angiography (CTA) examination for unilateral lower extremity trauma with normal contralateral lower extremities, including 89 males and 33 females, with an average age of(51.4±16.4) years old(ranged 18 to 81 years old). Picture archiving and communication system (PACS) was used to mark 11 lines including the surgical epicondylar axis (SEA) connecting the most prominent points of the lateral epicondyle and the deepest point of the sulcus on the medial epicondyle of the femur, axis of medial border of patellar tendon (MEPT)connecting the middle of the posterior cruciate ligament (PCL) and medial border of the patellar tendon at the level of a standard tibial cut from 8 mm distal of the lateral tibial joint surface, transverse axis of tibia (TAT) at the level of a standard tibial cut from 8 mm distal of the lateral tibial joint surface, Akagi line connecting the projected middle of the PCL and medial border of the patellar tendon at the tibial attachment, the axis of the medial 1/3 of patellar tendon(M1/3) connecting the projected middle of PCL and the medial 1/3 of the patellar tendon at the patellar tendon attachment level, Insall line connecting the projected middle of the PCL and the medial 1/3 of tibial tubercle, the axis of medial border of tibial tubercle (MBTT) connecting the projected middle of the PCL and medial border of tibial tubercle, as well as the axis of the proximal anterior tibial crest (PATC), axis 1 of the middle anterior tibial crest (MATC1), axis 2 of the middle anterior tibial crest (MATC2) and the axis of the distal anterior tibial crest (DATC) which were marked by connecting the 4 equidistant points on the sharp anterior tibial crest and the projected middle of the PCL. The angles between TAT and SEA as well as the angles between other axes and the perpendicular to SEA were measured. Pairwise differences among the 10 tibial axes were examined using One-Way ANOVA and paired t-test. RESULTS The angles between the axes of MEPT, Akagi line, M1/3, Insall line, MBTT, PATC, MATC1, MATC2, DATC and the perpendicular to SEA were (-1.6 ±4.5)° , (1.4 ±5.0)° , (10.2±5.1)°, (11.9±5.4)°, (3.6±4.8)°, (12.0±6.9)°, (7.2±8.6)°, (7.1±10.4)°, (6.6±13.5)°, respectively. The angle between TAT and SEA was (4.1±5.3)°. MEPT was external rotation compared to SEA. M1/3, Insall line and PATC were significantly greater than Akagi line, MBTT, TAT (P<0.001). MATC1, MATC2 and DATC were also significantly greater than Akagi line, MBTT axis and TAT (P<0.001). However, MATC1, MATC2 and DATC were also significantly less than M1/3 axis, Insall line and PATC(P<0.01). There were no significant statistical differences between MATC1, MATC2 and DATC(P>0.05). CONCLUSION The middle tibial anterior crest can be used as a reference for rotational alignment of tibial component in TKA, and its reliability is better than Insall line, but worse than Akagi line, TAT and MBTT.

Abstract
OBJECTIVE To observe the clinical effect of platelet rich plasma (PRP) combined with β tricalcium phosphate bioceramic bone in the treatment of non traumatic necrosis of the femoral head in ARCO stageⅡ. METHODS From January 2017 to December 2018, 100 patients (160 hips) with ARCO stageⅡnon traumatic necrosis of the femoral head were divided into PRP group and control group. In PRP group, 50 patients (80 hips), 22 males and 28 females, aged from 18 to 65 (43.47± 7.23) years, with a course of 4 to 18 (15.8±2.9) months, underwent core decompression and bone grafting combined with PRP implantation. There were 50 cases (80 hips) in the control group, including 27 males and 23 females, aged 20 to 63 (45.72± 7.43) years, and the course of disease was 6 to 19 (14.9±3.8) months. Hip X-ay film was followed up after operation. Harris score and VAS score were used to evaluate the curative effect, and the survival rate of hip joint was recorded. RESULTS All patients had good wound healing, no infection, thrombosis and other complications. All patients were followed up for 12 to 14 (12.0±0.4) months. Twelve months after operation, the image expression of PRP group was better than that of control group(P<0.05). Harris hip score and VAS score of pain at twelve months after operation were 89.98±6.17 and 1.68±1.02 in PRP group and 81.62±5.62 and 2.52±1.13 in control group, respectively. The survival rate of 96.25% in PRP group was significantly higher than 86.25% in control group. The postoperative score of two groups was higher than that before operation(P<0.05), but PRP group was better than control group at any time point statistical significance (P<0.05). CONCLUSION Platelet-rich plasma(PRP) combined with artificialbone for core decompression and bone grafting can change the situation of simple artificial bone implantation and uncertain curative effect, improve the success rate of this operation, effectively reduce the collapse rate of femoral head necrosis in the early and middle stage, delay or even avoid hip replacement.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. However, the pathogenesis of RA is not fully understood. Here, we reported that c-Jun NH2-terminal kinase (JNK)/stress-activated protein kinase-associated protein 1 (JSAP1, also known as JNK-interacting protein 3 (JIP3)) was significantly important for collagen-induced arthritis (CIA) in mice. Mice with JIP3 knockout (JIP3-/-) showed a significant decrease in arthritis index and swollen joint count in CIA mice. The histopathology of spleen and joint was markedly alleviated by JIP3 deficiency in CIA mice. Excessive macrophage activation in CIA mice was also inhibited by JIP3 deletion. CIA-induced RANKL/RANK/OPG system mRNA expression was blocked in JIP3-knockout mice. In addition, CIA-triggered cytokine secretion and TLRs/NF-κB activation was inactivated by JIP3-deficiency. In line with the inhibition of inflammation by JIP3-knockout, it also significantly suppressed JNK pathway activation induced by CIA, as evidenced by the down-regulation of p-JNK, p-c-Jun, AFT-2 and Elk-1 in joints. In vitro, RANKL-exposed RAW264.7 cells showed a significant reduction of osteoclast formation using TRAP staining. Moreover, JIP3 inhibition reduced the RANKL-caused expression of osteoclastic genes and inflammatory regulators, as well as activation of TLRs/NF-κB and JNK signaling pathways. Importantly, we found that promoting JNK activity could abrogate JIP3 knockdown-suppressed osteoclastic genes expression, inflammatory response and NF-κB activation. These findings suggested that JIP3 could significantly impede osteoclast formation and function by regulating JNK activation, illustrating a novel therapeutic strategy for managing arthritis and preventing bone destruction.

Abstract
The aim of this study was to evaluate the clinical effect of core decompression (CD), lesion clearance, and bone graft in combination with Tongluo Shenggu decoction for the treatment of osteonecrosis of the femoral head (ONFH).A total of 75 patients (92 hips), with ONFH at Association Research Circulation Osseous (ARCO) stages II to IIIA, were studied and divided into treatment group and control group. In control group, patients were treated with the CD in combination with autologous or artificial ceramic bone graft. In treatment group, patients were treated with the above method combined with Tongluo Shenggu decoction. Patients were followed-up at 1 month, 6 months, and 24 months after surgery. The visual analogue scale (VAS) scores, Harris Hip Score (HSS), and total effective rates were measured and recorded.The total effective rate of the treatment group was significantly higher than that of the control group (97.2% vs. 89.9%, P < .05). Compared with preoperative, the VAS and HSS scores were both improved at final follow-up, and there was significant difference between 2 groups (P < .01).The combination of CD, lesion clearance, and the bone graft with Tongluo Shenggu decoction is safe and effective for the treatment of ONFH, owing to which it can provide higher postoperative functional outcomes, reduce pain, and achieve smaller osteonecrosis area and better bone changes.

Abstract
Objective: To investigate the reliability of the distance between the tip of the greater trochanter and inter-teardrop line (GT-IT) in evaluating the leg length discrepancy (LLD) in patients underwent total hip arthroplasty (THA). Methods: Patients who underwent THA in Xi'an Honghui Hospital from August 2015 to February 2016 were enrolled in this study.The patients were measured for bilateral hips anterior-posterior (AP) radiograph preoperatively and postoperatively.Four distances measured, included: GT-IT, the tip of lesser trochanter and bi-ischial line (LT-BI); LT-IT and the anterior superior iliac spine and the medial malleolus (ASIS-MM). Magnification factor was considered when calculating absolute values.Intraclass correlation coefficient (ICC) was used to detect the reliability of the measurement data.Single factor analysis and paired t test were performed to compare data among the methods. Results: The ICC values of the four groups were greater than 0.80, which showed excellent agreement in the measurements.Single factor analysis of variance showed there were no statistically significant differences in the LLDs of the four groups preoperatively and postoperatively (F=0.914, 0.886, both P>0.05). There was no significant differences in preoperative and postoperative LLD between group GT-IT and group ASIS-MM, LT-BI or LT-IT(t=-1.544-1.114, all P>0.05). The LLDs were comparable between group LT-BI, ASIS-MM and LT-IT both preoperatively and postoperatively (t=1.577, 0.976, 1.344, -0.087, all P>0.05). And the LLD in group LT-IT and ASIS-MM were equivalent preoperatively and postoperatively (t=0.130, 1.063, both P>0.05). Bland-Altman plot illustrated high level of agreements between the four methods. Conclusion: Great reliability can be obtained with the GT-IT in evaluating the LLD in patients undergoing THA.

Abstract
UNLABELLED This study compares efficacy of ALN/D5600 versus that of calcitriol in osteoporotic Chinese postmenopausal women. ALN/D5600 produced greater bone mineral density (BMD) increases, greater bone turnover marker decreases, and less vitamin D insufficiency. This study provided detailed clinical information regarding ALN/D5600 treatment versus calcitriol 0.25 μg/day. The study did not evaluate fracture risk. INTRODUCTION The aim of this study is to investigate efficacy of alendronate 70 mg/vitamin D3 5600 IU combination tablets (ALN/D5600) versus calcitriol in osteoporotic Chinese postmenopausal women. METHODS This study is a 6-month, randomized, open-label, active-comparator study with 6-month extension (clinicaltrials.gov number NCT01350934) in postmenopausal women aged >55 years with osteoporosis (low bone mineral density (BMD) with/without prior fragility fracture). Patients were randomized to ALN/D5600 once weekly or calcitriol 0.25 μg daily. The primary efficacy end point of the base study was percent change from baseline in lumbar spine BMD (month 6). Hypercalcemia and hypercalciuria were safety events of special interest. RESULTS A total of 219 patients (ALN/D5600 n = 111, calcitriol n = 108) were randomized. Baseline characteristics were similar, 30.3 % baseline 25-hydroxyvitamin D (25(OH)D) ≤15 ng/mL. At months 6 and 12, changes in lumbar spine BMD from baseline were 3.5 versus 1.6 % and 5.2 versus 2.3 % for ALN/D5600 versus calcitriol (between-group differences p < 0.001), respectively. Between-group differences for ALN/D5600 versus calcitriol were significant (p < 0.001) at months 6 and 12 for change from baseline in procollagen type 1 N-terminal propeptide (-59.1 versus -16.8 %, -68.1 versus -17.0 %) and serum C-telopeptides (-79.2 versus -27.2 %, -76.2 versus -24.2 %). Drug-related adverse events (AEs) and discontinuations due to drug-related AEs occurred in 15 (14.0 %) versus 8 (7.4 %) patients and 3 (2.8 %) versus 0 patients in the ALN/D5600 and calcitriol group, respectively. Hypercalciuria 12-month incidence (24-h urine Ca >300 mg) was 8.4 (ALN/D5600) versus 13.9 % (calcitriol) (p > 0.05). One patient (calcitriol) had hypercalcemia. CONCLUSIONS ALN/D5600 produced greater increases in lumbar spine BMD and greater decreases in bone turnover markers versus calcitriol in osteoporotic Chinese women. It is not known whether the greater increase in BMD results in fewer fractures. ALN/D5600 was generally well tolerated in Chinese patients.

Abstract
Mycoplasma mycoides subsp capri is the cause of goat "MAKePS" (Mastitis, Arthritis, Keratoconjunctivitis, Pneumonia, Septicemia) syndrome. We identified three genes (GL_ 000459; 000461; 000462) as variable lipoprotein genes in the M. mycoides subsp capri str. PG3 genome by genomic information and comparative genomic analyses. To study the role of variable lipoproteins in M. mycoides subsp capri pathogenesis and evaluate the immunogenic and protective potentials of those proteins, we constructed the expression systems and expressed the mature peptide portion of the three proteins in E. coli. We also determined the titers and opsonophagocytosis activity of total IgG antibodies and the levels of Th1 and Th2 cytokines in sera, and we ran a lymphocyte proliferation assay in mice immunized with recombinant proteins His-tag-GL000459, His-tag-GL000461, and His-tag-GL000462. These three lipoproteins induced humoral and cellular immune responses in the immunized mice. Additionally, the whole blood opsonophagocitic in vitro assay demonstrated that the antibodies produced by the immunized groups can neutralize strain PG3; consequently, these three variable lipoproteins could be the major surface antigens in M. mycoides subsp capri str. PG3.

Abstract
Background It has been suggested that the formation of osteoblasts in bone marrow is closely associated with adipogenesis, and the balance between osteogenesis and adipogenesis differentiation of MSCs (mesenchymal stem cells) is disrupted in osteoporosis. In order to improve the treatment of osteoporosis, available agents with roles of regulating the balance is highly desirable. Emodin is a natural anthraquinone derivative extracted from Chinese herbs, which have been used to treat bone diseases for thousands of years. However, the underlying molecular mechanisms of emodin in modulating osteogenesis and adipogenesis remain poorly understood. Methods The molecular mechanisms of emodin on the processes of osteogenesis and adipogenesis in ovariectomized mouse and BMSCs (bone marrow mesenchymal stem cells) have been studied. We have analyzed the effects of emodin in vivo and in vitro. Female ICR mice were assigned to three groups: sham group, ovariectomy group, emodin group. Efficacy was evaluated by H&E, immunohistochemical assay and Micro-CT. In vitro, we analyze the effect of emodin—at concentrations between 0.1 μM and 10 μM-on the processes of inducing osteogenesis and inhibiting adipogenesis in BMSCs by ALP, Oil red O staining, real time RT-PCR and western blot. Results As our experiment shows that emodin could increase the number of osteoblast, BMD (bone mineral density), BV/TV (trabecular bone volume fraction), Tb.N (trabecular number) and Conn.D (connectivity density) of OVX (ovariectomized) mice and decrease the bone marrow fat tissue and adipocytes. The genes and proteins expression of osteogenesis markers, such as Runx2, osterix, collagen type I, osteocalcin, or ALP were up-regulated. While, the genes and proteins involved in adipogenesis, PPARγ, C/EBPα and ap2 were down-regulated. Conclusion It proves that emodin inhibits adipocyte differentiation and enhances osteoblast differentiation from BMSCs.

Abstract
OBJECTIVE To probe into the mechanism of the Chinese herbs with functions of reinforcing kidney and supplementing qi for preventing knee osteoarthritis of the rabbit. METHODS Totally 72 healthy Japan long-ear white rabbits, aged 4 months, were randomly divided into 6 groups, blank group (A), model group (B), high dose Chinese herb group (C), middle dose Chinese herb group (D), small dose Chinese herb group (E), aminoglucose hydrochloride capsule control group (F), 12 rabbits in each group. All the rabbits in the groups, except the group A, were fixed with plaster cast for six weeks to establish rabbit knee osteoarthritis. At the same time of modeling, the different doses of Juanbi Capsules and aminoglucose hydrochloride capsule were administrated intragastrically in the group C, D, E, F, respectively, for 4 weeks, for preventive treatment. In the group B, the rabbit was administrated intragastrically with equal volume of normal saline to the medication groups, twice each day, in the morning and the evening, and in the group A, nothing was administrated. After modeling for 6 weeks, the joint fluid was taken and TNF-alpha, IL-1 and IL-6 contents were detected with ELISA method, and the articular cartilage was taken for macroscopic and microscopic examinations. RESULTS In all the preventive treatment groups, the articular cartilage color changed to varying degrees with formation of osteophyte and bone cyst, superficial erosion on the chondral articular surface, and the cartilage defect reached to the mid layer in a part of specimens with cartilage exfoliation, but which in the extent were significantly lower than those in the model group. There were significant differences between the group A and B in TNF-alpha, IL-1 and IL-6 contents in the joint fluid (P < 0.05), indicating that the modeling is successful; and there were significant differences as group B compared with the group C,D, E, F, showing that TNF-alpha , IL-1 and IL-6 contents are decreased in all the medication groups; and significant differences between group C, D, E suggests that the increase of Chinese herb doses strengthened the effect of reducing TNF-alpha, IL-1 and IL-6 contents in joint fluid. CONCLUSION The Juanbi Capsule prevents osteoarthritis possibly through decreasing serum TNF-alpha, IL-1 and IL-6 contents.

Abstract
AIMS To evaluate the effect of Nidus Vespae extract and chemical fractions on the viability and architecture of Streptococcus mutans biofilms. METHODS AND RESULTS The raw material was first extracted using 95% ethanol/water. Subsequent fractions were prepared from this extract using cyclohexane/ethyl acetate, petroleum ether/ethyl acetate and chloroform/methanol. The biomass dry weight and total protein of samples treated with Nidus Vespae extract and chemical fractions were significantly less than those treated with the vehicle control (P < 0.05). Biofilms treated with Nidus Vespae also resulted in lower percentage of polysaccharide composition. The pH decrease in the biofilm matrix was retarded by Nidus Vespae compared with the vehicle control. Architecture of biofilms treated with Nidus Vespae was different than in the vehicle control and 0.05% chlorhexidine. CONCLUSIONS Chloroform/methanol fraction was the most effective treatment. SIGNIFICANCE AND IMPACT OF THE STUDY The significant antibiofilm activity demonstrated by Nidus Vespae shows it to be a promising source of novel anticariogenic agents.

Abstract
OBJECTIVE To evaluate the effect of compounds of Galla chinensis on the remineralisation of initial enamel carious lesions in vitro. METHODS Sixty bovine enamel blocks with early lesions were prepared and randomly divided into six treatment groups. The lesions were subjected to a pH-cycling regime for 12 days. Each daily cycle included 4x1min applications with one of six treatments; 1000ppm F aq. (as NaF, positive control); deionized water (negative control); or 4000ppm aqueous solutions of four G. chinensis extracts (GCEs); GCE, GCE-B, GCE-B1, or GCE-B2. Surface enamel microhardness was measured on the enamel blocks before and after demineralisation, and after pH-cycling, and percentage surface microhardness recovery (%SMHR) was calculated. The enamel specimens were then sectioned (thickness ca. 80microm) and examined by polarized light microscopy. RESULTS All samples rehardened significantly compared to baseline. Fluoride had a significantly greater effect than all other treatments. In the GCEs groups, %SMHR was significantly greater than DDW for the GCE, GCE-B and GCE-B1 groups. There was no significant difference between the GCE-B2 group and DDW. Polarized light microscopy showed that the thickness of the surface layer increased obviously in all specimens including NaF group, GCE group, GCE-B group and GCE-B1 group. Negative birefringent band appeared in the lesions body and the depth of the lesions was obviously reduced. CONCLUSION The present study has demonstrated the potential of three GCEs (GCE, GCE-B and GCE-B1) to effect net rehardening of artificial carious lesions under dynamic pH-cyclic conditions.
