Objective To find out about the allocation of large size medical facilities in Tangshan City so as to make rational use of its health resources. Methods On the spot investigations were combined with surveys through questionnaires to find out about the allocation of large size facilities in second tier hospitals and above in the city. Results There are altogether 109 large size medical facilities in the city, averaging 15.60 per million people. The allocation number is pretty high, and yet the distribution is quite irrational, with the city proper owning 70.67% of the facilities while its population and land area account for only 24.06% and 8.10%. Conclusion The allocation number has been increasing rapidly and the level of grade is rather high, and yet there lacks equity in distribution.

Objective To compare the efficacy and safety of tranexamic acid(TA)and norethisterone(NET)for the treatment of patients with ovulatory menorrhagia in China. Methods Onehundred and thirty one patients with proven ovulatory menorrhagia from gynecologic clinics of 5 teaching hospitals located in 4 different cities in China were enrolled during Jul 2004 to Dec 2006.Ameng them 128 completed the study.Patients were randomly divided into two therapeutic regimen groups:TA 1g thrice daily during menstrual cycle days(D)1-5,69 cases;or NET 5 mg twice daily on D19-26.59 cases.The drugs were administered for 2 consecutive cycles,then withdrawn and patients were followed-up for 1 more cycle.Data on menstrual blood loss [ estimated by pictorial blood assessment chart(PBAC)],length of menstrual periods,quality of life(QOL)evaluated by a 6 item health-related questionnaire were collectedbefore,during each cycle and were compared.Results Both treatments led to significant decreases of mean PBAC scores and shorter duration of menstrual periods,and improved the QOL ranking during the twotreatment cycles.The mean percentages of PBAC decrements in the TA first and second cycles were significantly greater than those in the NET corresponding cycles(35%VS 17%,P=0.004;4J4%VS 34%,P=0.04 respectively).The success rate of TA second cycle was higher than that of the NET second cycle (41%VS 24%,P=0.04).Improvement of QOL ranking in the TA first cycle was also significantly better than those in the NET first cycle ( P=0.03).The percentage of patients with at least 1 adverse event in TA group(19%)was significantly lower than that in NET group(35%,P=0.04).Patients'willingness tocontinue the treatment in the TA second and follow-up cycles(94%,79%respectively)were significantly higher than those in the corresponding cycles of NET groups(79%,59%respectively;P=0.01,P=0.02).Conclusion The regimen of TA 3 g daily during menstrual days 1-5 is a more effective and tolerable treatment than luteal phase norethisterone for patients with ovulatory menorrhagia.

OBJECTIVETo compare the therapeutic effects, toxic side effects and influence on the immune function in patients treated with TPF [docetaxel (DOC) + cisplatin (DDP) + 5-fluorouracil (5-Fu)] induction chronochemotherapy and conventional chemotherapy for locally advanced nasopharyngeal (NPC).

METHODSSeventy patients with locally advanced nasopharyngeal carcinoma were treated in our department at their first visit from April 2013 to December 2013. They were divided randomly into two groups: the chronochemotherapy group (38 patients) and conventional chemotherapy group (32 patients). All of the patients were treated with TPF regimen with 2 cycles of induction chemotherapy in a 21-28-days/cycle. The chronochemotherapy group: DOC: 75 mg/m2, i. v. gtt, d1 (03: 30-04: 30); DDP: 75 mg/m2, 10 am-10 pm, c.i.v, d1-d5; 5-Fu: 750 mg·m(-2)·d(-1), 10 pm-10 am, c. i.v., d1-d5, both chemotherapies were administered by intravenous infusion using an automatic electric pump. The conventional chemotherapy group: Both DOC and DDP were administered intravenously at a dose of 75 mg/m2 on d1. 5-Fu was given at a dose of 750 mg/m2 for 24 hours from d1-d5 with continuous infusion in a total of 120 hours. In this procedure, prescribing the conventional intravenous infusion, intensity modulated radiation therapy was used after the induction chemotherapy. The prescribed nasopharyngeal lesion dose (GTVnx) was 69.96 Gy/33 fractions for the T1-T2 nasopharygeal cancer, while 73.92 Gy/33 fractions nasopharynx lesion dose (GTVnx) for the T3-T4 nasopharyngeal cancer. The planning target volume (PTV) of positive lymph node (PTVnd) dose was 69.96 Gy/33 fractions. Concurrent chemoradiotherapy: cisplatin 100 mg/m2, i. v. gtt. d1-d2, and there were two cycles in total and 21 days each cycle.

RESULTSSixty-six patients were evaluable for the response assessment. There were 36 patients in the chronochemotherapy group and 30 patients in the conventional chemotherapy group. After the induction chemotherapy, no CR case was found in both of the two groups. The PR was 80.6% in the chronochemotherapy group and 50.0% in the conventional chemotherapy group (P=0.009). After concurrent chemoradiotherapy, the CR rate in the chronocheotherapy group was 45.5%, significantly higher than 20.7% in the conventional chemotherapy group (P=0.040). Secondly, the incidence rates of adverse reactions including bone marrow suppression, nausea, vomiting, diarrhea, constipation, oral mucositis, fatigue, anorexia in the chrono-chemotherapy group were significantly lower than that in the conventional group (P<0.05 for all). Finally, compared the two groups, the CD4+ /CD8+ ratio was significantly lower in the chronochemotherapy group than that in the conventional chemotherapy group (P<0.05). The lymphocytes CD19+ and CD4+/CD8+ were decreased and CD3+, CD4+, CD8+, CD16++CD56+ were increased in the chronochemotherapy group, while only CD3+ and CD8+ were increased in the conventional chemotherapy group.

CONCLUSIONSCompared with the conventional chemotherapy, the chronochemotherapy may be more favorable in the treatment of NPC, with a better therapeutic effects and effectiveness than that of conventional chemotherapy after induction chemotherapy, with less side effects, and can improve the immune function in the patients.

Objective To investigate the efficacy,adverse reactions and immune function of time-adjusted chemotherapy combined with intensity-modulated radiation therapy (IMRT) and conventional chemotherapy combined with IMRT for locally advanced nasopharyngeal carcinoma.Methods Random number grouping method was used to divide 66 cases of locally advanced nasopharyngeal carcinoma into 2 groups,of which 36 cases in the time-adjusted chemotherapy group and 30 cases in the conventional group.Both of them received docetaxel + cisplatin + fluorouracil regimen to induce chemotherapy for 2 cycles.The time-adjusted chemotherapy group was treated with intravenous injection of electronic automatic injection pump,the conventional group was treated with conventional intravenous infusion,and both groups were treated with synchronous cisplatin combined with IMRT.Calculated survival rate was generated by Kaplan-Meier method and long-term adverse reactions was evaluated according to CTC 3.0 criteria.Results The 3-year overall survival (OS) rate was 86.1％ and 93.3％ in the time-adjusted chemotherapy group and the regular group,the 3-year progress-free survival (PFS) was 83.3％ and 93.3％,the 3-year RFS was 88.5％ and 93.3％,and the 3-year recurrence-free survival was 94.1％ and 100％ respectively with no statistically significant difference (P ＞ 0.05).The dryness and hearing loss of the time-adjusted chemotherapy group had a decreasing trend compared with the conventional group.However,CD3 +,CD3 + CD4 +,CD3 + CD4 + CD8 +,and CD4 +/CD8 + of the time-adjusted chemotherapy group had an increasing trend compared with the conventional group.Conclusions Both time-adjusted chemotherapy and conventional chemotherapy combined with IMRT had comparable mid-term efficacy,but the former had lower adverse reactions,improved quality of life and immune function.Trial registration Chinese clinical trial registry,ChiCTR1800016809
