Eight patients with malignant tumors, testified by pathological examination. were treated by " Two-Route Chemotherapy" using a high dose of HD-Cisp latine in arterial infusion (AI). Among them 5 cases were primary or metastatic liver carcinoma, 3 cases were Ⅲ-Ⅳ stage breast carcinoma.One or two courses were given in each patient. The dosage of DDP in the first course was 80 - 100mg/m~2. the second was 120-150mg/m~2 with STS Ⅳ as a protective agent. The total lasted 14 courses.When DDF was given alone in AI, the serum creatine level increased temporarily, but there was no significant increase when both DDP and sodi um thiosulfate were given.Results: Among 5 cases of liver carcinomas I was complete response 3 were partial response and 1 was stable. Among 3 cases of Ⅲ-Ⅳ stage of breast carcinomas, all were partial response, giving a response rate of 8 (?) (7/8).

Topical photodynamic therapy (PDT),a highly effective,safe and non-invasive therapeutic method,exerts good therapeutic effects on various diseases in dermatology,such as actinic keratosis,condyloma acuminatum,acne,and so on.The major drawback of PDT is pain during the treatment.Some patients have to interrupt or terminate the treatment because of pain intolerance.Some progress has been made in the management of PDT-related pain.It has been revealed that multiple factors are associated with PDT-related pain,including individual factors,lesion characteristics,therapeutic parameters (such as light sources,photosensitizers).Many methods can be used to manage PDT-related pain,including local cooling,oral analgesics,two-step irradiance protocol,topical anesthesia,injection anesthesia,inhalation anesthesia,transcutaneous electric nerve stimulation,hypnosis.

Objective To investigate whether no asphyxia neonates with intrauterine distress are complicated with myocardial injury and determine the sensitive biochemical diagnostic parameters. Methods A total of 89 neonates born in the First Affiliated Hospital of Sun Yat-sen University from July 2009 to December 2009 were enrolled. Fifty-three fetal distress cases with Apgar score ＞ 7 at 1 and 5 minites were enrolled in the study group; while the rest 36 healthy neonates, whose Apgar score = 10 at 1 and 5 minites, were the control group. Umbilical artery blood samples of all cases were collected for blood gas analysis and biochemical measurement. Results(1)pH(7.23±0.07) and BE [(-4.8±3.0)mmol/L] in the study group were significantly lower than pH (7.31 ±0.03) and BE [(-2.1±1.5)mmol/L] in the control group (P＜0.05).The lactic acid of study group [(5.2±2.3)mmol/L] was higher than that of the control group [(2.3±1.1)mmol/L], and the difference was significant (P＜0.01). However, there was no significant difference between the two groups in PaO2[(16.2±7.9)mm Hg(1 mm Hg=0.133 kPa) vs. (17.5±6.7)mm Hg] and PaCO2[(54.0±11.2)mm Hg vs. (48.5±5.4) mm Hg; P＞0. 05]. (2) The level of CK-MB in neonates with fetal distress[(48 ±59) U/L] was significantly higher than that of healthy neonates [(36±27)U/L]. However, no significant difference was found in CK [(194±73)U/L vs. (162±95) U/L]and BNP levels[(519±309)ng/L vs.(481±216)ng/L;P ＞ 0.05]. (3) Spearman rank correlation analysis showed that CK-MB level was negatively correlated with pH(r=-0.296, P＜0.05) and BE (r=-0.318,P＜0.05) of umbilical artery blood,while BNP level was positively correlated with umbilical lactic acid (r=0.278, P＜0.05). No correlation was found between other parameters (P＞0.05).Conclusions Intrauterine distress without neonatal asphyxia had effect on fetal myocardial injury. CK-MB can be used as a sensitive parameter for monitoring the development of myocardial injury. The severity of myocardial injury was related to fetal acidosis.
