Pharmaceutical preparations, particularly as a "secret recipe" of traditional Chinese medicine in medical institutions, are the product of China's medical and health industry, and they are also an important means of competing of different medical institutions. Although pharmaceutical preparations have advantages and characteristics than institutes for drug and pharmaceutical companies, the quality standards of pharmaceutical preparations in medical institutions has not reached the desired level over the years. As we all know, the quality of pharmaceutical preparations is important to ensure the efficacy, especially under the environment of people pay more sttention on drug safety and effectiveness and contry increase emphasis on the stste of pharmaceutical preparations. In view of this, we will improve the grade, stability, and clinical efficacy of pharmaceutical preparations by the advanced equipment, testing instruments and the process dynamic quality control technology. Finally, we hope we can provide new ideas for the quality control of pharmaceutical preparations.

OBJECTIVETo assess the prevalence rate of Helicobacter pylori (H. pylori) in blood serum, its affecting factors and isoforms (CagA,VacA )infection in the elderly people in Beijing.

METHODS2006 residents were investigated through household questionnaire in different areas of Beijing (urban, suburban and mountainous district), who were older than 60 years old. Serum H. pylori CagA, VacA and Ureas antibody was detected by immunoblotting.

RESULTSThe total H. pylori infection rate was 83.4% and the infectious rate of I form pathogenic H. pylori was 56.0%. The incidence rate in urban or suburban district was higher than that of in mountainous district (P < 0.001). I form H. pylori infection rate in people with heavy labor or young elderly were higher than that of intelegent work or older elderly (P < 0.05 ). I form H. pylori infection rate in people of low diet was higher than that of high protein diet (P < 0.001).

CONCLUSIONThe rate of H. pylori infection in blood serum was high among the elderly people in Beijing with most of it belonged to type I . However, significant differences were noticed on the distribution of isoforms in different age groups, areas, professions and diet habit.

OBJECTIVESTo evaluate the characteristic morphology of heel spur, and to investigate the relationship of heel spur and plantar heel pain.

METHODSFrom June 2005 to April 2009, 210 cases (254 feet) with heel spur (according to Denis Pain Scale) were divided into cases group 1 (P2, n = 46), 2 (P3, n = 44), 3 (P4, n = 42), 4 (P5, n = 36) and controls group (P1, n = 42). Three-dimensional reconstruction of heel spur was performed in all groups using volume rendering based on multi-slice CT data by Super Image orthopedics edition 1.0. The characteristic morphology of heel spur was observed and the data were measured and analyzed, involving the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.

RESULTSParts of cases groups displayed coarse arcuate edge and undersurface with one or more little heel spurs adhere to heel spur, of which the numbers were greater than controls group, especially in cases group 4. No significant difference of the width of basilar part of heel spur was found among 5 groups (F = 2.32, P > 0.05). However, obvious difference was found in the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur (F = 8.23, 6.82, 5.87, P < 0.05). Compared with the controls group, the angle between heel spur and planta pedis of cases groups had higher degrees, but the difference of the other data presented irregular.

CONCLUSIONSThe characteristic morphology of heel spur varies in patients associated with plantar heel pain. No correlation is found between the severity and the morphological data, including the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.

BACKGROUNDThe Fc receptor associated pathway might improve the immune responses against hepatitis B virus (HBV) as previously described by us. In addition, the Flt3 ligand (FL) has been reported to potentiate antigen presenting cells in vivo and may act as a potential adjuvant to boost antigen-specific immune responses. In this study, the immune efficacies of a set of fusion proteins of HBsAg and Fc and/or FL were evaluated in HBsAg transgenic mice.

METHODSThe fusion proteins composed of HBsAg and the Fc domain of murine IgG1 (HBsAg-Fc) and/or the Flt3 ligand, and yeast-derived recombinant HBsAg were used as immunogen to immunize HBsAg transgenic mice, respectively. Serum and liver HBsAg levels, serum anti-HBsAg and cytokine profile, and the activities of alanine aminotransferase (ALT)/AST were investigated after immunization.

RESULTSAfter six injections, the most pronounced decrease in serum and liver HBsAg levels was observed in the HBsAg-Fc immunized group. In addition, serum Th1 cytokines and ALT/AST activities were highest in this group, indicating an effective induction of a favorable cellular immune response. Interestingly, the fusion protein containing HBsAg-Fc and the Flt3 ligand stimulated an alternative Th1-type immune response featured with high level productions of tumor necrosis factor α (TNF-α) and monocyte chemoabstractant protein 1 (MCP-1), causing a more severe cytotoxicity in hepatocytes while showed less effective in reducing serum HBsAg level.

CONCLUSIONHBsAg-Fc is effective in eliciting both the humoral and cellular immune responses against HBsAg in HBsAg transgenic mice, which makes it a potential immunogen for the immunotherapy of chronic hepatitis B.

OBJECTIVETo investigate the effect of autologous dermal-fat strip grafting in penile augmentation and elongation.

METHODSFrom May 2004 to December 2010, 24 patients underwent penile enhancement with free dermal-fat strip grafting. Through suprapubic incision, the superior suspensory ligament and part deep suspensory ligament are cutted off to lengthen the penis. The resulted dead space is filled with the autologous dermal-fat strip (6.0-9.5 cm in length, 1.2-1.5 cm in width and 0.6-0.8 cm in depth) to enhance the penis.

RESULTSPrimary healing was achieved in 23 cases. Incisional fat liquefaction happened in one case which healed after dressing change. The penile appearance was satisfactory both at rest or erection. The penile length and circumference increased by 2.5-4.8 cm (average, 3.2 cm) and 1.8-3.0 cm (average, 2.4 cm), respectively. 18 patients were followed up for 3 months to 5 years. All the patients were satisfactory on the cosmetic and functional results. No complication happened.

CONCLUSIONSIt is safe and effective for penile augmention and elongation with autologous dermal-fat strip grafting and disconnection of penile suspensory ligament.

OBJECTIVETo investigate the applied anatomy of the blood supply of the cervicoacromial crossing flap and its feasibility in clinical application.

METHODS5 fresh adult and 10 forman fixed adult cadaver specimens were used. The arteries, veins, cutaneous arteries, subdermal vascular network, and vascular network of the superficial layer of deep fascia in the cervico-acromial area were observed and studied under the microscope. The frontier border of the cervico-acromial area is clavicle, the posterior border is the spine of scapula, the outer border is acromion and the inner border is cervical base.

RESULTS(1) The perforator branches concentrate at the front edge of trapezius muscle; (2) The vessel network around the front edge of trapezius muscle is abundant. Among the anastomosis, two or three anastomosis which across the area from the base of the neck to acromion can be observed in the axial of every cervico-acromial area. Abundant vessel network can be observed in the superficial layer of deep fascia.

CONCLUSIONSThe blood supply of the cervico-acromial flap is abundant, which constains constant perforator point. The cervico-acromial crossing skin flap can be applied with the rich blood supply and abundant vessel network in the superficial layer of deep fascia.

OBJECTIVETo understand the prevalence, consequences and risk factors of falls among urban community-dwelling elderly in Beijing.

METHODSA cross-sectional study was conducted in Longtan Community, Beijing. A total of 1512 individuals aged 60 years or over were selected by stratified cluster sampling. Data regarding the frequency of falls in the previous year, as well as circumstances, consequence and related factors of falls were collected from the elderly through face-to-face interviews with questionnaires in their home.

RESULTSThe prevalence of falls was 18.0% on the average among 1512 participants, higher in women (20.1%) than in men (14.9%) (P = 0.006), and increased with age (chi2(for trend) = 10.37, P = 0.001). The total rate of falls-induced injuries among the fallers was 37.7%. Falls usually resulted in soft-tissues bruises (58.7%), fear of repeated episodes of falls (58.8%), loss of independence and confidence in movement (35.7%) and even in hip fracture. In addition to the burden of medical care, falls also generated a big economic burden. Occurrence of falls was significantly associated with both intrinsic and extrinsic factors. The related factors of falls in the elderly included age > or = 60-70 years, femininity, less physical activities, fear of future falls, living alone, severely impaired vision, health problem-impacted activities of daily living, chronic diseases (diabetes, hypertension, postural hypotension, stroke sequela, cataract, arthritis, dementia and depression), medications (psychoactive, anti-diabetic), gait imbalance, high bed and faintly-lighted stairway.

CONCLUSIONThe prevalence of falls among urban community-dwelling elderly in Beijing is closely associated with significant associated with intrinsic and extrinsic factors. Efforts to prevent falls in the elderly should be made at community level.

OBJECTIVETo explore the impact of IFN-γ + 874 polymorphisms on the outcome in HLA matched sibling HSCT.

METHODSWe used PCR-sequence-specific primer analysis (PCR-SSP) to analyze the polymorphisms of IFN-γ + 874 T/A in 80 recipient and donor pairs from October 2005 to March 2008.

RESULTSRecipients having donors who possessed IFN-γ + 874 A/A genotype had significantly earlier neutrophil recovery compared with those having donors with non-A/A genotype (15 (11 - 27) days vs 18 (12 - 30) days, P = 0.029). And IFN-γ + 874 A/A in both recipients and donors further facilitated neutrophil recovery compared with others (13 (11 - 25) days and 19 (12 - 31) days, P = 0.019). Besides, IFN-γ + 874 A/A in recipients increased the probability of grade II-IV acute graft versus disease (aGVHD) and cytomegalovirus viraemia compared with IFN-γ + 874 T/A or T/T genotype (20% vs 4% P = 0.041, 43.6% vs 16.0% P = 0.032), which lead to increased 5-year transplant-related mortality (TRM) (33.7% ± 6.8% vs 12.0% ± 6.5%, P = 0.050) and decreased 5-year event free survival (EFS) \[(58.2 ± 6.7)% vs (84.0 ± 7.3)%, P = 0.032\] compared with the latter. IFN-γ + 874 A/A in both recipients and donors also significantly increased the probability of grade II-IV aGVHD and cytomegalovirus viraemia compared with the other (21.7% vs 5.9%, P = 0.050; 45.7% vs 20.6%, P = 0.020), which caused increased 5-year TRM \[(31.6 ± 7.5)% vs (13.6 ± 6.5)%, P = 0.048\] and decreased 5-year EFS \[(56.8 ± 7.3)% vs (79.4 ± 6.9)%, P = 0.037\] compared with the other.

CONCLUSIONIn HLA-matched sibling HSCT setting, the presence of IFN-γ + 874 T allele in recipients or in both recipients and donors significantly decreased the risk of grade II-IV aGVHD and CMV infection and increased EFS. While IFN-γ + 874 A/A in donors or in both recipients and donors was associated with shorter duration to neutrophil recovery.
