OBJECTIVE:To evaluate the present situation and tendency of antihypertensive drug use in the southwestern districts of China.METHODS:The sales volume,drug types,DDDs,DDDc of antihypertensive drugs from 2002 to 2004 in 62 hospitals in the southwestern districts of China were statistically analyzed.RESULTS:The sales volume of antihypertensive drugs counted 18%to 20%of total sales volume of cardiovascular drugs,with the mean annual increasing rate of 20%.The sales volumes of amlodipine and enalapril ranked the first,and the second in 2004.Among the 10 manufacturers,the sales volume of antihypertensive drugs produced by multinational companies reached 81.9%of total sales volume.CONCLUSION:The sale volumes of antihypertensive drugs and cardiovascular drugs have gone on increasing sharply,calcium antagonists and angiotensin-converting enzyme inhibitor drugs dominate in the antihypertensive drug market in the southwestern district.

OBJECTIVE:To provide reference for rational use of antineoplastic agents. METHODS:The utilization of antineo-plastic agents in 34 hospitals from Chongqing area during 2011-2013 was analyzed retrospectively in terms of consumption sum, DDDs and DDC,etc. RESULTS:The consumption sum of antineoplastic agents increased by 23.74%in 2012 compared with 2011, and increased by 36.89% in 2013 compared with 2012. DDDs of antineoplastic agents increased year by year except that of botanic antineoplastic agents decreased slightly in 3 years. The DDDs of Chinese patent medicines remained at the first place over the three years;the consumption sum of it took up the first place over the three years too. CONCLUSIONS:The consumption of antineoplas-tic agents in Chongqing is in line with the general tendency of drug consumption in China. Chinese patent medicines which have lit-tle side effect and low price occupy an important place among all antineoplastic agents in Chongqing area.

Objective To observe the efficacy and main complications of allogeneic hematopoietic stem cell transplantation(allo-HSCT)for 76 patients with hematopoietic malignancies.Methods From September 2001 to March 2007,76 patients received allo-HSCT in Department of Hematology,Xijing Hospital,Fourth Military Medical University.All cases included 24 acute myeloid leukemia(AML),15 acute lymphocytic leukemia(ALL)and 34 chronic myelogenous leukemia(CML)and 3 T cell lymphoma/leukemia.Donors were HLA-identical sibling(n=57),1 locus mismatched sibling(n=3),HLA-matched unrelated volunteer(n=9)and haplo-identical sibling(n=7).Conditioning regimen consisted of busulphan-cyclophosphamide or cyclophosphamide and total body irradiation plus Ara-c/VP-16.Graft versus-host disease prophylaxis was the standard methotrexate and cyclosporine combination.Anti-human thymocyte immunoglobulin(ATG)and CD25 monoclonal antibody was given in unrelated donor and haplo-identical HSCT.Results Totally 73 patients got sustained engraftment.Acute GVHD and chronic GVHD were found in 18/73(24.7%)and 24/73(32.9%)patients,respectively.Severe veno-occlusive disease occurred in 2 cases.Pure red cell aplasia was found in 5 patients with major ABO mismatched HSCT.With a follow-up of 3 to 76 months,43/76(56.6%))patients were still alive and 33/76(43.4%)died from leukemia relapse or transplantation-related complications.Conclusion Allogeneic heamatopoietic stem cell transplantation is an effective therapy for leukemia,especially in CML-chronic period and acute leukemia in complete remission,but there is high rate of relapse in patients with high-risk and refractory status before transplantation.

12 kinds of histochemical methods were adopted to evaluate the effects of gossypol optical isomers on the reproductive system of Wistar rats, following the administration of (?) and (+)-gossypol at a dosage of 30mg/kg daily, and(-)-gossypol at a dosage of 15 mg/kg daily, respectively for 2 or 3 weeks. (+)-gossypol has no an tifertility activity. (?) and (-)-gossypol caused kinetic disorder of spermatogemsis, and inhibited turnover of nuclear basic protein of the late, elongated spermatids in the testis. No changes in G6PDH and 30-HSDH histochmical reaction in Leydig cells, and ALP in the basement membrane of epididymis were observable reflecting that gossypol has no effect on synthesis and secretion of testosterone. Spermatozoa in the epididymis of rats treated with (?) and (-)-gossypol exhibited head and tail separation. The formazan deposits of reaction of LDH, LDH-X, MDH and ICDH located in sperm mitochondria appeared to become coarse and to reduce in quantity after (?) and (-)-gossypol treatment.

Objective To evaluate the clinical significance and prognosis of tetus with lateral ventriculomegaly.Methods We retrospectively analyzed 92 singleton pregnant women who were antenatally diagnosed with fetal ventriculomegaly by ultrasound in genetic conselling clinics,Department of Gynaecology and Obstetrics,Nanfang Hospital,Southern Medical University between August 2007 and August 2010.All participants were divided into three groups according to the width of the lateral ventricles:group A (10.0-12.0 mm,n＝50),group B (12.1-14.9 mm,n=38) and severe ventriculomegaly group (≥15.0 mm,n=4).All fetuses were followed up.Chi-square test(or Fisher's exact test),Bonfferoni method,Mann Whitney or Kruskal-Wallis test were used for statistics.Results In group A,B and severe ventriculomegaly group,18％ (9/50),65.8％(25/38)and 3/4 of fetuses were complicated with structural malformation,respectively (x2 =22.934,P =0.000),and statistical significance were found only between group A and B (x2 =20.798,P=0.000).The incidences of fetal chromosomal aberration were 4.0％ (2/50),7.9％ (3/38)and 0/4 in the three groups,respectively (x2＝0.878,P ＝ 0.645).Eventually,all four cases with severe cerebral ventriculomegaly were terminated.Among cases of mild ventriculomegaly,63 women continued the pregnancy (48 in group A and 15 in group B).The intrauterine improvement of group B was poorerthan that of group A (Z=-3.317,P =0.001).Respectively,three,ten and two cases of ventriculomegaly deteriorated,stabilized and regressed in group B,and the corresponding figures were 3,15 and 30 in group A.In group A,the prognosis of fetus with non-isolated ventriculomegaly was poorer than that of fetus with isolated ventriculomegaly (Z=-2.631,P=0.009).For neonates 14 days after birth (n=62),the rates of normal neonatal behavioral neurological assessment (NBNA) scoring were respectively 93.8％ (45/48) and 71.4％ (10/14) for groups A and B with statistical difference (Fisher's exact test,P =0.040).Bayley scales of infant development (BSID) used to evaluate infants at 12-month-old revealed that the psychomotor developmental index (PDI) between group A and group B had statistical difference (8,26 and 1 case of good,moderate and poor development in group A; one,seven and three cases in group B; Z=-2.203,P=0.043).However,the mental developmental index (MDI) between group A and B had no statistical difference.Twenty babies among the survived ones received magnetic resonance imaging (MRI) examination.The results showed that lateral ventricle width regressed in nine babies (45.0％) and progressed in one baby (5.0％).Ten cases (50.0％) did not change.The change of ventriculomegaly after birth was related to BSID evaluation.Better prognosis of fetuses were found in those with regressed ventriculomegaly (P=0.033).Conclusions Fetuses with mild ventriculomegaly (10.0 12.0 mm) have a favorable outcome.Further investigations,such as fetal development,chromosomal examination,intrauterine infection screening and MRI if necessary,are suggested for fetus with ventriculomegaly.Moreover,intensive intrauterine and postnatal follow-up is recommended.
