Objective To analyze the clinicopathological characteristics of patients with gastrointestinal malignant tumor in some parts of Hainan province and alien patients outside of Hainan province. Methods Three hundred and fifteen patients who were diagnosed by pathological confirmation were selected in Hainan Branch of PLA General Hospital from Jun 2012 to June 2016, clinicopathological parameters including age, gender, tumor location, cancer cell differentiation, body mass index (BMI), body surface area (BSA), value of preoperative tumor markers, TNM stages, microsatellite state, human epidermal growth factor receptor 2 (Her-2) staining, Ki-67 index and risk factors were collected and compared between local and alien patients. Results In contrast with patients outside of Hainan province, a significant lesser BMI [colorectal cancer: (23 ± 3) kg/m2 vs. (24 ± 4) kg/m2, t=-3.69, P< 0.05; gastric cancer: (21.50 ± 3.15) kg/m2 vs. (23.00 ± 3.61) kg/m2, t=-2.11, P=0.04] and BSA [colorectal cancer:[(1.73 ± 0.18) m2 vs. (1.82 ± 0.18) m2, t=-3.46, P<0.05;gastric cancer:(1.73 ± 0.16) m2 vs. (1.81 ± 0.18) m2, t=-2.09, P=0.04] were found in local patients. Local patients with colorectal cancer were much more younger [(57 ± 13) years old vs. (62 ± 13) years old, t=-2.30, P=0.02], with corresponding elevated positive rate of preoperative CEA (χ2=4.56, P= 0.03), T stages (χ2 = 8.31, P= 0.04) and TNM stages (χ2= 11.19, P= 0.01), however, no such difference was detected in gastric cancer patients (all P>0.05). Conclusions Patients with gastrointestinal cancer in some parts of Hainan province, in particular, colorectal cancer patients, present some exceptional clinicopathological features, which are marked by younger age at diagnosis, low level of BMI and BSA. In addition, preoperative level of CEA would be of important for these patients.

Objective To study effect of drug treatment in polycystic ovary syndrome patients withhyperprolactinemia.Methods We retrospectively studied 63 women with polycystic ovary syndrome and hyperprolactinemia from the Reproductive Medicine Center,Provincial Hospital between January 2005 andMarch 2007.According to the beginning time of bromocriptine,all women were divided into two groups.Group Ⅰ was composed of 48 cases who received bromocriptine administration before induction of ovulation cycles,and the dose of bromocriptine was modulated depending on the level of serum prolactin.When serum prolactin was controlled at normal levels,we decreased the dosage of bromocriptine step by step(1.25 mgonce),and then continued the treatment at maintenance dosage for no less than 3 weeks.After a baselineultrasonographic examination on day 3,patients were treated with clomiphene citrate at a dosage of 100 mg (2 tablets/day)for 5 days of a normal cycle or progesterone-induced bleeding.On day 9,we monitored the growth conditions of follicles routinely with trans-vaginal uhrasound.If there was no dominant follicle,we added human menopausal hormone(hMG,75 U/d)to the protocol.Human chorionic gonadotropin(hCG,6000-10000 IU)was given intramuscularly when the mean diameter of a follicle reached at least 18 mm.At the same time we instructed the patients to have sexual intercourses or carried out artificial inseminationsbefore and after ovulation.Group Ⅱ were 15 cases in which induction of ovulations were commenced almostsimultaneously with beginning of bromocriptine.The same protocol was given to patients in group Ⅱ.The procedures of ovulation induction and the outcomes of treatment were analyzed and compared.Results Compared with groupⅡ.the days of using hMG in Group Ⅰ was shorter by instructing the time of sexualintercourse.The difference was significant(P=0.004).And there were similar results in the artificial insemination cycles(P=0.009).The rate of pregnancy in group Ⅰ(40%,19/48)was higher than that in groupⅡ(27%,4/15),but the difference was not obvious(P=0.525).Conclusion Bromocriptine administration before the stimulated ovulation therapy can decrease the total dosage and treatment course of ovulating drugs.Induction of ovulations simultaneously with start of bromocriptine therapy can shorten the treatment time of infertility.

Objective To confirm the clinical diagnosis of complete androgen insensitivity syndrome (CAIS) by molecular genetic testing in a large family. Methods PCR was performed to amplify the coding region of androgen gene, followed by direct sequencing in the patients with CAIS and relatives in this family. Results A missense mutation Arg773His was identified in the patients (homozygous) and carriers(heterozygous). Conclusions Mutation Arg773His in the AR gene leads to CAIS in this family. Molecular genetic testing of CAIS facilitates not only prenatal genetic diagnosis but also preimplantation genetic diagnosis and offers genetic counseling for future pregnancies to abandon the transmission of the mutated X chromosome to the coming generation.
