Objective: To investigate the effects of Zhu Yun Pill(ZYP) in the treatment of infertility due to luteal phase defect(LPD).Methods: 163 infertility patients due to LPD were randomly divided into three groups in terms of ZYP group,progesterone group and combination group(ZYP and progesterone).Then the therapeutic efficacy was judged by the pregnancy rate(PR),endometrial biopsy,the level of serum hormone and basal body temperature before and after the treatment.Result: 40 women were pregnant in ZYP group(cure rate,33.33%),8 in the progesterone group(cure rate,26.67%) and 9 in the combination group(cure rate, 69.23%).The symptomatic amelioration and total effective rate of ZYP group were obviously higher than single exogenous progesterone group(P

Objective:To investigate the association between anxiety and the change of humoral immune functions and its correlation with HLA-DQB1 polymorphisms.Methods:Total 31 resident doctors were selected randomly and tested by State-Trait Anxiety Inventory(STAI).IgG,IgA,IgM,complement C3 and complement C4 were detected with BECKMAN array360 system;HLA-DQB1*02、*03、*04、*05 and*06 alleles were individually amplified by polymerase chain reaction(PCR)using exon2 group-specific primers.The correlation between immune function and HLA-DQB1 polgmorphisms were investigated.Results:Statistical analysis showed that there was positive correlation with State Anxiety (Ta) and complement C3,either Trait Anxiety (Tc) and complement C3.There was significant difference between HLA-DQB1*02 positive and negative in Ta (P＜0.05),while no difference in complement C3(P＞0.05).There was significant difference between HLA-DQB1*04 positive and negative in Ta and Tc(P＜0.05),while no difference in complement C3(P＞0.05).Conclusion:Anxiety could change some humoral immune functions and this is related with HLA-DQB1 polymorphism.

The pathogenesis of diabetic retinopathy (DR) is more complex. For the upstream of traditional pathogenesis, to looking for unifying mechanism theory which proposed in foundation of common promoters and the latest view of DR may be the result of chronic inflammation. Both of them provide the basic and clinical theraby of DR with new direction. Therefore, there are many related issuess till needs to intensive study.

Local recurrence and distant metastasis is the major factor of impacting long-term survival for patients with esophageal carcinoma after radical resection. Postoperative radiotherapy and chemotherapy is expected to reduce the rate of local recurrence and distant metastasis, but views for the value of postoperative radiochemotherapy were inconsistent in the past. In recent years, scholars have performed much more clinical studies on postoperative radiotherapy and chemotherapy and found that the combined postoperative radiotherapy and chemotherapy after surgery significantly reduces the recurrence rate and distant metastasis rate and can enhance the survival of the patients.

Objective To investigate the effect of continuous blood purification(CBP) in the patients with severe acute pancreatitis(SAP). Methods Twenty-six patients with severe acute pancreatitis were divided into the control group and the observation group randomly. Fourteen cases in the control group were given conventional treatment only, 12 cases in CBP group were given continuous blood purification as well as the conventional treatment. The APACHE Ⅱ score and CRP of pre- and intra-treatment at the 2nd and 5th day were observed in the two groups. The duration of mechanical ventilation, the duration of ICU stay, the mortality of hospital were observed as well. Results The APACHE Ⅱ score and CRP of the second day and the fifth day of intra-treatment in the control group were 1.61±3.00,10.76±4.30, (149.71±60.06) mg/L and (101.21±33.98) mg/L, respectively, which were significantly different to those of (8.20±1.87) mg/L, (6.19±1.49) mg/L, (109.17±23.91) mg/L,(70.83±25.45)mg/L in the CBP group(P＜0.05). The duration of mechanical ventilation,the duration of ICU stay and the mortality of hospital were (13.29 ± 6.23) d, (16.00 ± 6.86) d, 21.43% in the control group, which were significantly lower than those of (8.00 ±5.27)d,(10.33 ±4.81)d,8.33% in the other group (P ＜0.05).Conclusions CBP is an effective method for the patients with severe acute pancreatitis to shorten the duration of mechanical ventilation and the ICU stay,and decrease the mortality of hospital.

In the hospital administration,the establishment and the implementation of the strategic planning of the hospital occupies a very important position.This paper,combined with the actual situation of a children's hospital in Chongqing,describes the hospital rational use of three level management system of the hospital,office,department,in order to get the full investigation of the national macro policy,the development of the medical industry and the status of the hospital and other aspects,and then supports efficient workflow to complete the hospital strategic planning.This paper also focuses on the target implementation,program implementation and project implementation of three levels,in order to illustrate the process for the implementation of the strategy to provide a reference of.hospital strategic planning formulation and implementation.

Objective To investigate the effects of hyperoxic-hyperosmotic sodium chloride solution(HHSCS) on arterial blood gas and blood lactate in rabbits with hemorrhagic shock, and evaluate the HHSCS effects on hemorrhagic shock resuscitation.Methods Hemorrhagic shock models were induced in 30 male rabbits.The median arterial pressure(MAP) was declined to 40mmHg within 10 minutes,then maintained for 60(minutes).The animals were then randomly divided into 3 groups:normal saline hyperoxic solution(NSO)group,hyperosmotic sodium chloride solution(HS)group and HHSCS group.Sixty minutes later,NSO,HS or HHSCS 6ml/kg was infused intravenously in 5 minutes.Heart rate(HR) 、respiratory rate(RR)、 MAP and urine drops(UD) before shock and after fluid infusion were recorded;blood lactate(BL) and blood gas were measured before shock,60min after shock,and 30min,60min,120min postinfusion.Finally,the(rabbits) were killed by bleeding,the lungs were observed in autopsy,and the lung coefficient was measured.Results HS and HHSCS more effectively raised MAP,enhanced heart function,and increased UD than NSO.HHSCS group significantly reduced BL.At 60,120min after infusion,SaO_2 in HHSCS group was(significantly) higher than that in HS group and NSO group(P

Objective To investigate the clinic effect of hypocellular acute myelogenous leukemia (AML) patients with CAG regimen. Methods 29 cases with hypocellular AML were treated with CAG regimen. Results There were 14 cases achieved complete remission (CR), accounting for 48.3 %; 7 cases partial remission (PR), accounting for 24.1%. The total effective rate was 72.4 %, inducing 7 cases of NR, one case dead in early time. Conclusion CAG regimen has been proved to be effective in shortening the period of reduced peripheral blood granulocytes and decreasing the death rate related to chemotherapy, hence,a secure and effective therapy in treating hypocellular AML.
