Chinese Journal of Postgraduates of Medicine 2017;40(3):196-199
Objective To study the effect of gamma globulin on serum immune index in neonates with neonatal pneumonia. Methods One hundred neonates with neonatal pneumonia were selected, and they were divided into control group and observation group by random digits table method with 50 cases each. The control group was treated with conventional treatment, and the observation group was treated with conventional treatment combined with gamma globulin. The treatment efficacy, various signs disappearing times, length of stay in hospital and immune indexes were compared between 2 groups.Results The total effective rate in observation group was significantly higher than that in control group:96.00% (48/50) vs. 72.00% (36/50), and there was statistical difference (χ2 = 10.71, P<0.01). The disappearing times of cough, crackles, perioral cyanosis and fever and the length of stay in hospital in observation group were significantly shorter than those in control group:(4.39 ± 1.46) d vs. (6.32 ± 1.61) d, (4.21 ± 0.93) d vs. (5.36 ± 1.08) d, (0.83 ± 0.15) d vs. (1.16 ± 0.22) d, (2.53 ± 1.04) d vs. (4.47 ± 1.13) d and (7.68 ± 0.87) d vs. (10.03 ± 1.18) d, and there were statistical differences (P<0.01). The IgG, IgA, IgM, CD4+and CD4+/CD8+levels after treatment in observation group were significantly higher than those in control group: (10.32 ± 2.86) g/L vs. (6.88 ± 0.83) g/L, (1.14 ± 0.13) g/L vs. (0.91 ± 0.25) g/L, (0.94 ± 0.21) g/L vs. (0.85 ± 0.27) g/L, 0.516 ± 0.068 vs. 0.385 ± 0.063 and 1.89 ± 0.35 vs. 1.57 ± 0.33, but the CD8+was significantly lower than that in control group:0.303 ± 0.046 vs. 0.349 ± 0.048, and there were statistical differences (P<0.05). Conclusions The gamma globulin can not only significantly improve the curative effect in neonates with neonatal pneumonia and promote the recovery of the clinical symptoms, but also improve the efficiency of cell immunity and humoral immunity ability. It is a kind of effective treatment.

Objective To investigate the effect of the aqueous extracts from Dioscorea nipponica Makino (AEDN) against the carbon tetrachloride (CCl4)-induced mice acute liver injury by regulating TLR4/MyD88 signal pathway.Methods 60 mice were randomly divided into control group, model group, low, medium and high dose AEDN groups according to radom number table with 10 mice in each group. Mice in low, medium and high dose AEDN groups were adiminstrated with 50, 100 and 200 mg/kg AEDN, in control and model groups were adiminstrated with solvent once a day for 7 consecutive days. Two hours after the last administration, mice were intraperitoneal injected with with 0.3% CCl4 olive oil solution to induce acute liver injury model, except for the mice in control group. Twenty-four hours after injection, the expressions of TLR4, MyD88 and NF-κB in liver tissue were evaluated by Western blot, mRNA levels were evaluated by PCR, and the AST and ALT levels in serum were also detected.Results Compared with model group, the serum AST (98.00 ± 17.75 U/L, 57.49 ± 9.66 U/L, 39.60 ± 9.49 U/Lvs. 113.40 ± 9.71 U/L) and ALT levels (76.00 ± 14.73 U/L, 50.70 ± 9.35 U/L, 35.25 ± 9.93 U/Lvs. 95.42 ± 11.64 U/L) were significantly decreased in low, medium and high dose AEDN groups (P<0.01); MyD88 (0.67 ± 0.21vs. 1.74 ± 0.42), NF-κB p65 (0.51 ± 0.09vs. 1.76 ± 0.31) and TLR4 (0.97 ± 0.25vs. 2.99 ± 0.72) levels were down-regulated in high dose AEDN group (P<0.01); the mRNA levels of IL-6 (2.22 ± 0.25, 1.76 ± 0.31vs. 5.20 ± 0.60), IL-1β (1.96 ± 0.35, 1.47 ± 0.23vs. 7.37 ± 0.99)、TNF-α (2.06 ± 0.25, 1.34 ± 0.33vs. 2.98 ± 0.50) in medium and high dose AEDN groups significantly decresed (P<0.01).Conclusions The AEDN has protective effect against CCl4-induced acute liver injury in mice via adjusting TLR4/MyD88 signal pathway.

Objective To evaluate the clinical efficacy of early enteral nutrition combined with additional parenteral nutrition (EEN + PN) versus TPN (total parenteral nutrition) in patients after conventional pancreaticoduodenectomy (PD).Methods From January 2009 to January 2013, 340 consecutive patients who underwent conventional PD with Child's reconstruction at the First Affiliated Hospital of Xi'an Jiaotong University were enrolled into this single-center retrospective comparative study.There were 87 patients in the EEN + PN group and 253 patients in the TPN group.The preoperative baseline characteristics,histopathological types, intraoperative parameters and postoperative outcomes were recorded and compared between the two groups.Results There were no significant differences in the preoperative general characteristics data, pathological patterns, and intraoperative details.There were significantly higher rates in delayed gastric emptying (DGE), morbidity (15.9% vs 6.7%, P < 0.05), and pneumonia (10.3% vs 3.6%, P < 0.05);significantly prolonged nasogastric tube removal time (5.6 ± 0.2 days vs 3.9 ± 0.1 days, P<0.05), and increase in hospitalization expenses (65 397.0 ± 861.2) Yuan vs (50 663.9 ± 239.2) Yuan, P < 0.05) in the EEN + PN group when compared with the TPN group.Conclusions EEN + PN after conventional PD was associated with increased rates of DGE and pneumonia, prolonged nasogastric tube removal time, longer EN duration and increase in hospitalization expenses.Hence, EEN should only be performed prudently and selectively.

A case of cicatricial female pattern hair loss was reported. A 36-year-old female patient presented with gradually aggravated hair loss for more than 10 years. Skin examination showed diffuse hair thinning on the scalp, thin and soft hairs, and some pencil eraser-sized areas of focal atrichia. TrichoScan examination revealed markedly decreased hair density on the forehead, variability in hair diameter greater than 20%, and increased proportions of vellus hairs. Dermoscopic examination showed increased numbers of vellus hairs, plenty of focal atrichia areas measuring 3 - 5 mm in diameter, loss of some follicular ostia, and confluent white dots. Histopathological examination of vertical and transverse scalp sections showed predominantly distributed miniaturized hair follicles with lichenoid folliculitis around the infundibulum and isthmus, concentrically layered perifollicular fibrosis, a marked decrease in the number of hair follicles compared with healthy people of the same age, increased proportions of vellus hairs, a large number of miniaturized hair follicles and follicular streamers, and formation of follicular micro-scars. The patient was diagnosed with cicatricial female pattern hair loss. She received topical treatment with 5% minoxidil liniment once a day, and alternate treatment with topical tacrolimus ointment and clobetasol propionate ointment, as well as oral spironolactone at a dose of 20 mg twice a day and compound glycyrrhizin capsules at a dose of 50 mg thrice a day. After half a year of treatment, there was no marked aggravation of hair loss, and the follow-up continued.

A case of fibrosing alopecia in a pattern distribution (FAPD) and its clinicopathological, dermoscopic and TrichoScan features were reported to improve the understanding of FAPD. A 23-year-old male patient presented with progressive hair loss on the forehead and top of the head for 10 years, local hair thinning and softening, and occasional scalp itching. Skin examination showed diffuse sparseness of hair from the forehead to the top of the head, frontal hairline recession, focal thinning and softening of hair, some follicular keratotic papules and perifollicular erythema on the alopecic area, with no obvious scales. TrichoScan examination revealed markedly decreased hair density and increased proportions of vellus hairs. Dermoscopy showed loss of some follicular ostia and confluent white dots. Histopathological examination of the scalp showed lichenoid lymphocytic infiltration around the infundibulum and isthmus of hair follicles, concentrically layered perifollicular fibrosis, hair follicle destruction, formation of follicular micro-scars, markedly increased variation in the diameter of residual follicles, and some vellus hairs. The patient was diagnosed with FAPD. FAPD is easily misdiagnosed as androgenetic alopecia, and early diagnosis and treatment are needed.
