  • THE ADVANCES IN THE RELATION OF FEMALE HORMONE TO PRIMARY GALLBLADDER CARCINOMA

    Objective To study the effects of estrogen and progesterone and their receptors on the development of gallstone (GS) and primary gallbladder carcinoma (PGC), and probe to the relationship between the biological characteristic of PGC and female hormone and their receptors. Methods The study of PGC related to female hormone was reviewed by history document and experimental study in resently. Results The female hormone influenced human body extensively: they acted on not only the target organs, but also the nontarget organs with their receptors. The action was brought about by their receptors expression. The action intensity was dependent on not only the serum level of female hormone but also their corresponding receptors distributing in organs. The carcinogenic mechanism of estrogen was more clear with the discovery of estrogen-regulating-proteins. Conclusion The estrogen play an important role in the onset and development of GS and PGC. Estrogen and progestrone can inhance the patients′ susceptibility to the cholesterol gallstone and become a high risk factor in causing PGC through inducing their corresponding receptors expression in the gallbladder. Evaluating the effects of estrogen-estrogen receptor-estrogen-regulating-protein on biological characteristic of PGC is significant in guiding clinical endocrine treatment.

  • Efficacy and safety of tocilizumab in the treatment of active rheumatoid arthritis

    ObjectiveTo evaluate the efficacy and safety of tocilizumab for treating active rheumatoid arthritis (RA).MethodsSeventy-seven patients with active RA who treated from November 2013 to April 2015 in the Outpatient Department of Rheumatology in West China Hospital of Sichuan Universiy with follow-up data were involved. Their clinical data were retrospectively analyzed. Tocilizumab was infused every 4 weeks at a dose of 8 mg/kg and concomitant use of other disease-modifying anti-rheumatic drugs (DMARDs) was allowed. Activity and efficacy were evaluated by Disease Activity Score-28 (DAS28) and European League Against Rheumatism (EULAR) response.ResultAfter the treatment, the DAS28 devreased from the baseline 6.88±1.09 to 4.99±1.53 (4th week), 4.31±1.37 (8th week), 3.74±1.15 (12th week) and 2.66±0.68 (24th week) (P<0.05). The disease activity level assessed by DAS28 was 11.1%, and the low activity was 9.5%, and the values were 10.5%, 32.2% and 66.6%, 16.7% (P<0.05) respectively at the 12th and 24th week. EULAR good/moderate response rates were 17.5%/76.2%, 39.0%/57.4% and 66.7%/33.3% at 8, 12 and 24 weeks. The differences in the decline over time in tender joint count, swollen joint count visual analogue score, Health Assessment Questionnaire score, erythrocyte sedimentation rate and C-reactive protein before and after the treatment were statistically significant (P<0.05).

  • Evaluation of Shunting Flow Differences in Varied Conditions in a Simulated Adult Cardiopulmonary Bypass Model

    Abstract: Objective To evaluate different shunting flow in varied conditions in a simulated adult cardiopulmonary bypass (CPB) model under normothermia. Methods We established the pseudo adult patient undergoing CPB at four different shunting states with devices of heartlung machine, heatcooler, an adult membrane oxygenator and arterial filter. In state 1, purge line of the arterial filter was open alone; In state 2, purge line combined with 6.5 mm tubing hemoconcentrator shunting was open; In state 3, purge line combined with 5 mm tubing hemoconcentrator was open; In state 4, purge line combined with blood cardioplegia shunting was open. The flow of preoxygenator and postfilter was recorded with ultrasonic flowmeter, and the pressure of purge line and postarterial filter was also detected. Results At state 1, when the pump flow was invariable, the percentage of the shunting flow increased with the increase of postfilter pressure. However, when the postfilter pressure was constant, the percentage of the shunting flow decreased with the increase of the pump flow. The purge line pressure increased with the increase of the postfilter pressure at a constant pump flow under state 1. The shunting flow of state 2 was the largest among all the four states. The shunting flow of state 3 was similar to that of state 4. All the purge line pressure was lower than the postfiler pressure of the circuit in the four states. Conclusion Under states of different shunting opening, different degrees of blood flow are diverted away from the arterial line. The shunting flow increases at a lower pump flow and a higher postfilter pressure. A flow probe located in the postfilter line may be necessary to monitor realtime arterial flow.

  • Relationship Between the Bacterial Spectrum Difference of Gallbladder Mucosa and Choledochus Bile and Clinical Prognosis of Gallstone Pancreatitis

    【Abstract】ObjectiveTo study the relationship between the bacterial spectrum difference of gallbladder mucosa and choledochus bile and clinical prognosis of gallstone pancreatitis. MethodsA synchronic bacterial culture and drug sensitivity test were carried out on 48 patients with gallstone pancreatitis. ResultsThe cases of positive gallbladder mucosa and choledochus bile were 13 (27.1%) and 31 (64.6%) respectively. The cases of double positivity were 12 (25.0%). The cultural strains of gallbladder mucosa and choledochus bile were significantly different. Some strains were only found in choledochus bile,whereas in gallbladder mucosa L-form bacteria predominated.ConclusionThe most common causative strain of gallstone pancreatitis is Bacterium coli. The drug-resistant strain emerges maybe due to bacterium immigration and delitescence in gallbladder mucosa. L-form bacteria should be considered when using antibiotics, because L-form bacteria have close relationship with the prognosis of gallstone pancreatitis.

  • Idiopathic inflammatory myopathies associated interstitial lung disease

    Idiopathic inflammatory myopathies are a group of connective tissue diseases characterized by nonsuppurative inflammation of the striated muscle. At present, the diagnostic criteria for polymyositis/dermatomyositis classification proposed by Bohan and Peter in 1976 is mainly used clinically. In clinical observations, it is found that myopathy involves not only skin and muscle but also affects many systems of the body. Interstitial lung disease occupies an important part, and it is an important cause of death of patients with inflammatory myopathy. Patients with idiopathic myositis should be examined as early as possible by high-resolution CT to improve the detection rate of myositis-associated interstitial lung disease and start treatment as soon as possible. At the same time, the patients with myositis have different clinical manifestations due to specific antibodies in the serum; some specific antibodies may indicate poor prognosis and poor treatment response. Timely screening of patients with positive myositis-specific antibodies in patients with the pulmonary interstitial disease can help the patient’s diagnosis and treatment process.
