In this paper, we describe mismatch, chaos, and disorder behavior during healthcare seeking. Such structural imbalances, scarcity and surplus make healthcare services less efficient. We give reasons for such phenomena in terms of long-term effects of health resource allocation policy-making and implementation, inherent de-fects within healthcare insurance, incomplete market development, and cultural issues. We then propose four policy strategies, including rational price mechanism, strict referral healthcare system, confidence in basic healthcare facili-ties, and proper healthcare cultures. These will restore orderly healthcare behavior and help realize expectations for the current healthcare reform in China.

Acute and chronic graft rejection are the major factors leading to graft non-function.There is an active expression of chemokines early after transplantation.They recruit T cells and antigen presenting cells selectively to the graft, leading to inflammatory reaction and finally to graft non-function.Accordingly,monitoring the expression status of chemokines and their receptors regularly may help to the diagnose rejection.To determine one or more chemokines or their receptors as the new targets for anti-rejection therapy will be of great clinical significance.This review focuses on the research progression in the above areas.

The folate metabolic pathway plays important roles in cellular physiology by participating in nucleotide synthesis, DNA repair and methylation, and maintenance and stability of the genome. Methylenetetrahydrofolate reductase (MTHFR) is a key regulatory enzyme involved in folate metabolism. Polymorphisms of MTHFR may change the level of homocysteine and affect DNA synthesis and methylation, leading to an increased oxidative stress and disturbed methylation reactions and consequently affecting reproductive function. This article presents an overview on MTHFR gene polymorphisms, proposing that multicentered, large-sample and long-term prospective studies are needed to reveal the relationship between MTHFR gene polymorphisms and infertility.

Objective To evaluate the surgical treatment of old patients with acute perforated gastroduodenal ulcer. Method The age, complications, duration of the disease history, operative method, systemic inflammatory response syndrome (SISR) and multiple organ dysfunction syndrome (MODS) in 89 old patients with acute perforated gastroduodenal ulcers were analyzed retrospectively. Results Simple closure operation was performed in 78 cases and subtotal gastrectomy in the other 11 cases. Twelve patients died. The mortality and complications rate were significantly lower in the patients less than 70 -year old than those in the patients more than 70-year old (P

Objective To explore the effect of Jinmaitong (JMT) on expression of Bax, Bcl-2 and Caspase-3 in hippocampal neurons culturedwith high glucose. Methods Hippocampal neurons were primarily cultured and purified from the hippocampus of new-born SpragueDawley rats. Neuron-specific enolase immunocytochemical method was adopted for the identification of the neurons. They were divided intonormal control group, high glucose group, high-dose JMT (JH) group, middle-dose JMT (JM) group, low-dose JMT (JL) group and a positivecontrol group. 72 hours later, Western blotting was adopted to detect the expression of Bax, Bcl-2 and Caspase-3. Results Comparedwith the normal control group, the expression of Bax and Caspase-3 in the high glucose group significantly increased (P<0.01), and the expressionof Bcl-2 significantly decreased (P<0.05). Compared with the high glucose group, the expression of Caspase-3 and Bax in the positivecontrol group and JH, JM, and JL groups significantly decreased (P<0.01), and the expression of Bcl-2 significantly increased (P<0.05).Compared with the positive control group, the expression of Caspase-3 and Bax significantly decreased in JH, JM, and JL groups (P<0.05),and the expression of Bcl-2 significantly increased in JH and JM groups (P<0.05). Conclusion JMT may reduce apoptosis by inhibiting theexpression of Bax and Caspase-3 and promoting the expression of Bcl-2.

Objectives:To explore the influence of nutritional support treatment on patients with the injured pancreatitis. Methods:The twenty five cases with injured pancreatitis were divided into research group (13 cases of 1997-2001, with nutrition support) and control group (12 cases of 1992-1996,without nutritional support). Blood composition, biochemistry, complications, hospitalization time and mortality were compared between two groups. Results:WBC, amylase, glucose, transaminase and BUN were beginning to decrease in two days, and reached to normal limits in 6～7 days in research group. Lymphocyte count after treatment in research group was significantly different ( P

Objective To evaluate and analyze the postoperative complications induced from the procedure for prolapse and hemorrhoids(PPH).Methods The data of the third or fourth degree hemorrhoids operated by pro- cedure for prolapse and hemorrhoids were analyzed.Results Total 224 patients with hemorrhoids were operated on by PPH,and the mean operative time was 25 minutes and mean postoperative hospital stay were 3.5 days.Postoper- ative bleeding requiring haemostatic procedures occurred in two patients.Urine retention rate was 30.36%,there were 56 eases pain scores＞5,there of re-prolapse,16 cases of residual skin tags.One case of mucocele.Conclusion The rule of PPH is individual management.

A molecular template synthetic polymer highly selective for norfloxacinum was prepared by a molecular imprinting technique. The selective binding characteristics of the template polymer was evaluated by Scatchard analysis. The multiple-sites binding model was used to calculate the maximum numher of binding sites and the dissociation constant. The results showed that the template polymer using methacrylic acid (MAA) as functional monomer could form two kinds of binding sites. The dissociation constants were estimated to be Kd1 = 2.9 × 10-5mol/L and Kd2 = 3.2 × 10-3 mol/L. The selective binding experiment for substrates indicated that the polymer gave much higher affinity and selectivity for norfloxacin than for acid pipemidic and cefalexin. It is possible to be a good adsorption and binding material in the selective enrichment and determination of trace norfloxacin in complex biosamples.
