Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Along with increasing degree of population aging globally， senility， good health and long life have become the focus of the world. Guided by Qiluo doctrine， an essence， Qi and spirit theory is proposed as below， essence is the origin of life， Qi is the impetus of life and spirit is the embodiment of life. Based on holistic view of kidney deficiency involving the five internal organs and injuries of the five internal organs definitely affecting the kidney， a mechanism of aging is proposed as below， deficiency of kidney essence is the foundation of aging， deficiency of promordial Qi is the key of aging and physical and spiritual loss is the manifestation of aging. It provides a theoretical guidance for anti-aging study of rejuvenating the elderly and making the strong person stronger. By virtue of the experiences in kidney-tonifying medication accumulated for more than two thousand years， Bazi Bushen capsules has been developed， which has anti-aging efficacy， including tonifying kidney， replenishing essence， coordinating Yin and Yang， supplementing primordial Qi and nourishing body and spirit. Experimental researches have demonstrated that Bazi Bushen capsules can improve overall aging and systemic aging， as well as prevent and treat aging related diseases. Preliminary clinical studies demonstrate that this capsules can enhance athletic ability and improve sexual function， and is expected to become a representative Chinese patent medicine of anti-aging. This paper addresses aging and anti-aging on the basis of Qiluo doctrine， in the hope of helping prevention and treatment of aging related diseases.

The decline of body function and senile diseases caused by aging seriously affect human health and life span， which is an important topic in the field of life science. Bazi Bushen capsules is a representative Chinese patent medicine for tonifying essence， invigorating Qi and anti-aging， guided by Qiluo doctrine， and essence， Qi and spirit theory. Previous pharmacological and clinical studies have confirmed that this preparation has the comprehensive advantages of anti-aging， and prevention and treatment of aging-related diseases. Among them， pharmacological studies showed that Bazi Bushen capsules had the effect of improving the appearance status of mice， improving the level of sex hormones， inhibiting the formation of atherosclerosis， improving cardiac function， improving learning and memory cognitive ability， improving neurological function， improving osteoporosis and muscle function， improving sperm count and quality. The mechanism was related to the up-regulation of the recombinant sirtuin （SIRT6） level， down-regulation of the levels of aging-related proteins p53 and p16， up-regulation of telomerase reverse transcriptase level， and alleviation of inflammation and oxidative response. Clinical studies have proved that it can improve the symptoms of patients with kidney essence deficiency， improve exercise ability， and improve the sexual function of impotence patients. Anti-aging research of Bazi Bushen capsules based on Qiluo doctrine fully embodies the new mode of academic innovation and transformation of traditional Chinese medicine （TCM） with the combination of "theory-new drug-experiment-clinic"， which has made a demonstration for the anti-aging research of TCM.

OBJECTIVE: To compare the effect of moxibustion combined with basic treatment and simple basic treatment on the clinical symptoms, renal function and hypercoagulable state in patients with idiopathic membranous nephropathy (IMN) of low to medium risk with spleen-kidney deficiency and blood stasis. METHODS: A total of 60 patients with IMN of low to medium risk with spleen-kidney deficiency and blood stasis were randomized into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 1 case dropped off). In the control group, the conventional basic treatment of anti-hypertension, regulating blood lipid and anti-coagulation was adopted. On the basis of the control group, moxibustion was applied at Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4), Zusanli (ST 36) and Sanyinjiao (SP 6) in the observation group, once a day, 5 days a week continuously with 2 day interval. The treatment of 6 months was required in the both groups. Before treatment and 3 and 6 months into treatment, the total TCM syndrome score, the renal function indexes (24-hour urinary protein quantity [UTP], albumin [ALB], urea nitrogen [BUN] and creatinine [Scr]), the blood coagulation indexes (fibrinogen [FIB], D-Dimer [D-D], p-selection and von Willebrand factor [vWF]), total cholesterol (TC) and triacylglycerol (TG) levels were observed, and the therapeutic efficacy was evaluated on 3 and 6 months into treatment in the two groups. RESULTS: The effective rates of 3 and 6 months into treatment were 78.6% (22/28) and 89.3% (25/28) in the observation group, which were higher than 62.1% (18/29) and 75.9% (22/29) in the control group respectively ( CONCLUSION Moxibustion combined with basic treatment can effectively improve the clinical symptoms, renal function and renal microcirculation in patients with idiopathic membranous nephropathy of low to medium risk with spleen-kidney deficiency and blood stasis, the therapeutic effect is superior to the simple basic treatment.

BACKGROUNDThe properties of subchondral bone influence the integrity of articular cartilage in the pathogenesis of osteoarthritis (OA). However, the characteristics of subchondral bone alterations remain unresolved. The present study aimed to observe the dynamic alterations in the microarchitecture, mineralization, and mechanical properties of subchondral bone during the progression of OA.

METHODSA medial meniscal tear (MMT) operation was performed in 128 adult Sprague Dawley rats to induce OA. At 2, 4, 8, and 12 weeks following the MMT operation, cartilage degeneration was evaluated using toluidine blue O staining, whereas changes in the microarchitecture indices and tissue mineral density (TMD), mineral-to-collagen ratio, and intrinsic mechanical properties of subchondral bone plates (BPs) and trabecular bones (Tbs) were measured using micro-computed tomography scanning, confocal Raman microspectroscopy and nanoindentation testing, respectively.

RESULTSCartilage degeneration occurred and worsened progressively from 2 to 12 weeks after OA induction. Microarchitecture analysis revealed that the subchondral bone shifted from bone resorption early (reduced trabecular BV/TV, trabecular number, connectivity density and trabecular thickness [Tb.Th], and increased trabecular spacing (Tb.Sp) at 2 and 4 weeks) to bone accretion late (increased BV/TV, Tb.Th and thickness of subchondral bone plate, and reduced Tb.Sp at 8 and 12 weeks). The TMD of both the BP and Tb displayed no significant changes at 2 and 4 weeks but decreased at 8 and 12 weeks. The mineral-to-collagen ratio showed a significant decrease from 4 weeks for the Tb and from 8 weeks for the BP after OA induction. Both the elastic modulus and hardness of the Tb showed a significant decrease from 4 weeks after OA induction. The BP showed a significant decrease in its elastic modulus from 8 weeks and its hardness from 4 weeks.

CONCLUSIONThe microarchitecture, mineralization and mechanical properties of subchondral bone changed in a time-dependent manner as OA progressed.

OBJECTIVEFabry disease is a rare lysosome storage disease featuring X-linked recessive inheritance. The study was to explore potential mutations of alpha-galactosidase A (GLA) gene and their correlation with clinic manifestations in three Chinese pedigrees with Fabry disease.

METHODSAll exons and flanking sequences of GLA gene were amplified with PCR. Potential mutations were detected with bidirectional DNA sequencing. Correlation between particular mutations and clinic features were analyzed.

RESULTSA unreported missense mutation, c.797A>C (D266A) in GLA exon 5 was identified in pedigree 1. Also in exon 5, a missense mutation c.644A>G (N215S) was found in pedigree 2. In pedigree 3, a nonsense mutation c.355C>T (Q119X) was found in exon 2. The c.797A>C mutation was not detected in 200 unrelated male controls. The probands of pedigrees 1 and 3 had presented mainly with skin damage and chronic renal insufficiency, whilst the proband of pedigree 2 had presented with hypertrophic cardiomyopathy.

CONCLUSIONThe unreported c.797A>C (D266A) mutation is the sixth missense type mutation of the 266th codon of GLA gene, and all other 5 missense mutations reported previously had been confirmed to be responsible for Fabry disease. The c.797A>C mutation, not found in 200 unrelated male controls, may be the causative mutation in pedigree 1. The c.644A>G and c.355C>T mutations were first detected in Chinese patients. Variable phenotypes of Fabry disease may be in part attributed to the natures of particular mutations of GLA gene.

OBJECTIVETo timely summarize past experience and to provide more pertinent reference for control and prevention in A/H1N1 cases in influenza season.

METHODSDuring May 25 to 31, 2009, 2 secondary community cases caused by a influenza A/H1N1 imported case. In the close contacts of 3 A/H1N1 cases, 14 had some aspirator symptoms onset, such as fever (> or = 37.5 degrees C), cough, sore throat and etc. Laboratory tests excluded the infection of A/H1N1 influenza. For throat swab test for the 14 cases, 7 were tested for seasonal influenza virus. A face-to-face or telephone interview was conducted by CDC staff to collect information of 62 close contacts.

RESULTSOf 14 fever cases, there was no significant by differences by age[15-age group: 19.2% (5/26), over 25-age group: 25.0% (9/36); chi(2) = 0.287, P = 0.592]; by sex group [24.0% (6/25) for male and 21.6% (8/37) for female; chi(2) = 0.048, P = 0.826], by working units [dressing and design, photograph, saleroom and others, consumer group: 42.1% (8/19), 27.3% (3/11), 12.5% (2/16) and 6.3% (1/16); chi(2) = 7.653, P = 0.054], by dormitory style [dormitory style = 33.3% (4/12), non-dormitory style = 29.4% (10/34); chi(2) = 0.699, P = 0.403]. All the cases had fever (37.5 - 37.9 degrees C), no case had diarrhea. One in 3 A/H1N1 cases had diarrhea. All the 14 cases were negative result for A/H1N1 RNA. Six from 7 cases were positive for seasonal influenza test.

CONCLUSIONThis was a seasonal influenza outbreak happened in the close contacts of first confirmed A/H1N1 cases in community in mainland China. It showed that we should exclude the seasonal influenza in the investigation of A/H1N1 cases in the seasonal influenza period in some time. It is necessary to take effective measure to strengthen the control and prevention of seasonal influenza.
