Microbial metabolomics is a subject that chiefly studying all the low molecular weight metabolites in an organism or cells during their growing process. The progress of analytical technology promotes microbial metabolomics to make advancement. In this paper, the commonly used analytical technology, sample preparation and its application were discussed and the prospects of the analytical methods were also discussed.

OBJECTIVETo investigate and clarify the key surgical techniques and evaluate clinical effectiveness of modular cementless femoral stems(LINK MP modular stem) in complex revision hip arthroplasty.

METHODSFrom January 2002 to December 2013, 470 patients in Chinese PLA General Hospital received revision hip arthroplasties using MP stems. Among them, 246 patients were followed for an average of 5.7 years (ranged, 0.5 to 11 years). There were 148 males and 98 females, with an average age of 62.5 years old (ranged from 26 to 83 years old). The most common reason for revision was aseptic loosening of femoral stems (107 cases, 43.5%), followed by prosthetic joint infection (104 cases, 42.3%). Other reasons included unexplained hip or thigh pain, periprosthetic femoral fracture, prosthesis wear and dislocation. According to Paprosky classification of femoral deficiency, there were 171 cases of type IIIA (69.5%), 14 cases of type I, 39 cases of type II, and 22 cases of type IIIB. The average preoperative Harris hip score (HHS) was 37.4 ± 7.5. In addition, radiographic presentation, degree of patients' subjective satisfaction, and clinical effectiveness were assessed as well.

RESULTSThe average Harris score was im- proved to 87.8 ± 4.2 after operation,with significant statistical difference when compared to preoperative score (t = 92.13,P = 0.00). Analysis of patients' subjective satisfaction for leg length discrepancy, stability and overall degree of satisfaction showed that the number of patients with great satisfaction were 27, 60, 61 respectively. The most common complication was the periprosthetic fracture (intraoperatively 21 cases and postoperatively 8 cases). Other complications included infection (7 cases), dislocation (5 cases), numbness possibly caused by incomplete sciatic nerve injury (6 cases) and thigh swelling (3 cases). The X-ray taken at the final follow-up revealed that prosthesis subsidence occurred in 4 cases, 2 of which needed a second revision.

CONCLUSIONThe application of modular cementless femoral stems (LINK MP modular stem) in complex revision hip arthroplasty (especially in cases with the serious defect of proximal femoral bone) shows good results at both the short-term and long-term follow-up, especially in the revision for prosthetic infection with the high success rate. In order to avoid complications and improve clinical outcomes,the surgeons should carefully select proper surgery candidates,perform the procedure with care, and master the key surgical techniques.

Emotion theory is an important part of TCM theory. Huangdi Neijing systematically explains emotion theory and its clinical application from the aspects of physiology, pathology, treatment, and health preserving, and constructs relatively complete emotion theory system of TCM, which becomes the foundation of development of emotion theory for later generations. Deep discussion on emotion theory and adjusting methods in Huangdi Neijingis not only with important theoretical significance, but also with high clinical application values.

A 49-year-old male was admitted to Peking Union Medical College Hospital presented with fever for more than half a year. The patient was diagnosed as Sjogren′s syndrome at local hospital. After oral prednisone 60 mg per day was given, the fever alleviated, but recurred after prednisone tapered to 40 mg/d. Both blood culture and stool culture were positive for Salmonella enteritidis. Antibiotics including ceftazidime, ceftriaxone, cilastatin-imipenem were sequentially administrated for 4 weeks, yet not effective. Although there were not respiratory symptoms or certain abnormalities on high-resolution chest CT, arterial blood gas indicated hypoxemia. Serum lactate dehydrogenase and β2 micro-globulin were elevated, and the lung function test demonstrated significant impairment of diffusion function. Positron emission tomography-computed tomography (PET/CT)scan suggested that high fluorodeoxyglucose uptake was diffusely seen in both lungs. The patient was finally diagnosed as pulmonary intravascular large B-cell lymphoma (IVLBCL) by transbronchial lung biopsy. This case aims to emphasize the differentiation diagnoses of pulmonary intravascular lymphoma from common situations.

Objective To investigate the prognostic factors of cervical high-grade squamous intraepithelial lesions treated by cold knife conization with negative margin.Methods Two hundred and sixty-six women with cervical high-grade squamous intraepithelial lesions treated by cold-knife conization with negative margins at Beijing Hospital between Jan 1999 and Jan 2004 were analyzed retrospectively.All patients were followed up with cytology,high-risk human papillomavirus(HPV)test and eolposcopy if necessary.Results The cervical CIN recurrence rate was 8.6% with no incidence of invasive cervical cancer after a median follow-up of 46 months.The recurrence was related to the grade of lesions and gland involvement pathologically.One of 20(5.0%)cases with cervical intraepithelial neoplasia(CIN)Ⅱ,9 of 164(5.5%)cases with CIN Ⅲ(excluding carcinoma in situ,CIS)and 13 of 82(15.8%)cases with CIS recurred(P
