Objective To investigate the effect of clinical risk factors including maternal underlying medical conditions on the development of preeclampsia (PE) in order to improve and strengthen the early assessment of high clinical risk population of PE.Methods Clinical.observational data of patients with PE in Peking University Third Hospital from November 2008 to January 2011 were analyzed.Comparative analysis was made among medical conditions with PE (M-PE) sub-group and isolated PE (I-PE) sub-group and non-PE pregnancy with or without medical conditions (control group).Results Totally 159 cases,43.09% (159/369) of total cases of PE had high clinical risk factors (multiple pregnancy and medical conditions) and 32.3% (97/300) of singleton PE accompanied with medical conditions.The incidence of PE in singleton pregnancies with medical conditions was significantly higher than those without medical conditions [ 15.0% (97/646) versus 4.45% (210/4719),P < 0.05 ].In M-PE sub-group,the average age [ ( 31.7 ± 4.5 ) versus ( 29.3 ± 5.2) year-old] and body mass index (BMI) in first trimester [ (26.0 ±5.6) versus (23.3 ± 3.7) kg/m2],the proportion with previous preeclampsia [ 11% (11/97) versus 4.9% (10/203) ] and pregnancy loss in third trimester [ 11% ( 11/97 ) versus 3.0% ( 6/203 ) ],were higher than those of I-PE sub-group ( all P < 0.05 ).The onset of preeclampsia in M-PE sub-group was earlier than I-PE ( 32.9 versus 34.4 gestation weeks,P < 0.05 ).The proportion serious cases of PE occurring before 32 gestational weeks were higher in M-PE than that of I-PE sub-group [ 45% (44/97)versus 34.0% (69/203),P <0.05].Multivariate regression analysis showed that previous history of late pregnancy loss and irregular prenatal care were clinical risk factors for early-onset PE whether early-onset was defined as < 34 or < 32 gestational weeks respectively (all P < 0.05) ; medical conditions were risk factors for PE if early-onset was defined as < 32 gestational weeks ( OR =1.718,95% CI:1.005 - 2.937,P =0.048).Conclusions Multiple pregnancies and pregnancies with medical conditions exceed one-third of total subjects of PE.The onset of PE in subjects with maternal underlying medical conditions was earlier which is the subgroup should not be ignored.The difference of early pregnancy BMI may show the maternal heterogeneity in early onset and late onset of preeclampsia.Assessment of clinical risk factors including the underlying medical disorders for preeclampsia in early trimester should be strengthened.

Objective To investigate the relationship between potential maternal risk factors between potential maternal risk factors in different level hospitals as well as different prenatal care patterns and characteristics of preeclampsia. Methods A retrospective study of 300 preeclamptic singleton patients delivered in Peking University Third Hospital was performed.Patients were divided into three groups:regular prenatal care in tertiary hospitals (n =100),regular prenatal care in primary hospitals (n=81) and without prenatal care (n=119). The onset of preeclampsia and incidence of severe preeclampsia of different groups were analyzed. Non-parametric and Chi-square test were adopted for continuous and categorical variables respectively. Results (1) In total cases of preeclampsia subgroup (I-PE subgroup) and with chronic hypertension (CH subgroup),the diagnosis of preeclampsia was later in patient with regular prenatal care in tertiary hospital (patient-TH)[100,64 and 14 cases,37.1 (4.1),37.3 (1.7) and 36.3 (2.5) weeks respectively] than those with regular prenatal care in primary hospital (patient-PH) [81,54 and 9 cases,32.9 (6.7),33.8 (6.1)and 27.9(6.3) weeks respectively] (Z=72.29,51.30 and 14.58 respectively,P<0.05) or the patient without regular prenatal care (patient-NP) [119,85 and 19 cases,31.6(6.6),31.9(6.7) and 30.3(4.7) weeks respectively] (Z=86.69,58.83 and 11.33 respectively,P<0.05).The proportion of severe preeclampsia occurred earlier than 32 weeks [13.0% (13/100) vs 55.5% (66/119),9.4%(6/64) vs 50.6%(43/85),and 35.7%(5/14) vs 89.5%(17/19); x2=43.95,29.42 and 10.17respectively,P<0.05] or earlier than 34 weeks [17.0% (17/100) vs 65.5% (78/119),14.1%(9/64) vs 61.2%(52/85) and 42.9%(6/14) vs 94.7%(18/19); x2 =47.71,31.18 and 10.61 respectively,P<0.05] were lower in patient-TH than in patient-NP.(2) In patient-NP and patientPH,onset of preeclampsia was earlier in CH subgroup compared with I-PE subgroup (Z=26.61 and 22.82,P< 0.05). In patient-NP,the proportion of severe preeclampsia occurred earlier than 32 weeks (x2 =9.11,P<0.05) or earlier than 34 weeks (x2 =7.95,P<0.05) was higher in CH subgroup than in I-PE subgroup. Conclusions Regular prenatal care in tertiary hospital might effectively delay the onset of preeclampsia or severe preeclampsia,especially in patients with risk factors for preeclampsia. Assessment of risk factors for preeclampsia in early trimester should be strengthened and individualized prenatal care plan should be established.

OBJECTIVE:
To investigate the clinical effects of the combined modality therapy for the patients with difficult-to-treat rhinosinusitis (DTRS).
METHOD:
The clinical data involving 42 patients with DTRS were analyzed retrospectively. All patients received revision endoscopic sinus surgery (ESS) and combined modality therapy systematically and individually. The clinical effects of all patients were observed 6- and 12-month following revision ESS.
RESULT:
Forty-two patients were followed up for 6 months, whereas 35 patients were followed for 12 months post operation. VAS scores of the patients significantly improved (P < 0.01) 6- and 12-month after revision ESS, but there was no statistic difference (P > 0.05) between 6- and 12-month post operation. Moreover, Lund-Kennedy scores by endoscopy significantly improved (P < 0.01) 6- and 12-month following ESS. Similarly, there was no statistic difference (P > 0.05) between 6- and 12-month postoperatively. Additionally, within 6 months follow-up, 16 of 42 patients (38.1%) were cured, 19 of 42 patients (45.2%) were improved, and 7 of 42 patients (16.7%) were ineffective. The total effective rate in all patients was 83.3% 6 months postoperatively. While within 12 months follow-up, 11 of 35 patients (31.4%) were cured, 15 of 35 patients (42.9%) were improved, and 9 of 35 patients (25.7%) were ineffective. Hence, the total effective rate in 35 patients was 74.3% after 12-month follow-up. There was no statistic difference (χ² = 1.019, P > 0.05) between 6- and 12-month postoperatively.
CONCLUSION
Appropriate revision ESS plus the combined modality therapy has been proven to be an effective method for the treatment of DTRS. The clinical effects in this study are significant and stable, and thus it is worthy of further clinical applications.

Objective To evaluate the choices and surgical skills for tension-free femoral hernia repair under local anesthesia. Methods The clinical data of 109 nonincarcerated femoral hernia patients were summarized from December 2002 to December 2009. Patients were divided into 3 groups according the time period at which the surgery was performed. 85 patients from 2002 to 2008 were divided into 2 groups,45 cases treated with preperitoneal repair ( preperitoneal group), and the other 40 cases with mesh-plug repair (plug group). The 24 cases admitted from January 2009 to December 2009 received modified preperitoneal repair. Operation time, VAS, length of hospitalization, incidence of recurrence, foreign body feelings and seroma were compared among the three groups. Results All the 109 patients were repaired under local anesthesia, and there was no perioperative death. The statistical indicator value of incidence of recurrence, foreign body sensation and seroma in preperitoneal group was lower than plug group (P <0.05). The modified preperitoneal repair was better in operation time, VAS, length of hospitalization than preperitoneal group (P < 0.05). Conclusions Modified preperitoneal repair under local anesthesia is the choice for treating femoral hernia without incarceration. Modified preperitoneal repair is faster, more minimally invasive and faster recovery.

Objective To determine the causes and risk factors of antimicrobial treatment failure in patients with community-acquired pneumonia(CAP). Methods Hospitalized adults with CAP from January 2006 to December 2006 were analyzed retrospectively. Treatment failure was defined as appearance of nonresponding pneumonia and progressive pneumonia. Patient's clinical features were analyzed. Results All of 378 patients were involved in this study. Total antimicrobial treatment failure was happened in 50 patients(32 patients with non-responding pneumonia and 18 patients with progressive pneumonia). The causes were infectious (35 patients,70% ), non-infectious (11 patients,22% ) and undetermined (4 patients,8% ).Mortality of antimicrobial treatment failure was 18%(9/50, 8 patients died of infectious cause, 1 patient had no clear cause of death). Stepwise Logistic regression analysis showed that C-reactive protein, multilobar pneumonia,albumin < 30 g/L,renal function lesion,liver function lesion were related with antimicrobial treatment failure. Independent factors of treatment failure were multilobar pneumonia (P= 0.002) ,albumin <30 g/L(P = 0.001 ) and renal function lesion (P = 0.000). Conclusion The major challenge associated with antimicrobial treatment failure in hospitalized patients with CAP is infection, most of which is infection of drug resistant strain.
